    To address the issue of low fruit setting rates caused by low temperatures and insufficient sunlight during the flowering period of Myrica rubra Dongkui,this study investigated the effects of pruning period and foliar nutrition on fruit setting rate and fruit quality of Myrica rubra.The results showed that under spring pruning treatment,the fruit setting rate reached 14.44%,which was significantly(p<0.05)higher than the no pruning treatment by 4.87 percentage points. Compared with spraying clear water(CK),foliar spraying of potassium dihydrogen phosphate+Cuikanghuaguoling (nutrient solution) under spring pruning can significantly increase fruit setting rate by 5.29 percentage points. The single fruit weight and soluble solids content were 24.84 g and 12.14%,respectively,which were significantly increased by 16.13% and 1.20 percentage points than those of CK. The fruit had good nutritional quality in terms of total sugar,total acid,vitamin C,total amino acids,and anthocyanin content. The yield per plant was 82.46 kg,which was 115.41% higher than that of CK. The commercial fruit rate was 78.56%,and the premium fruit rate was 63.91%. The experiment suggests that the pruning period and foliar nutrition are the key factors affecting the fruit setting rate of Myrica rubra. Spring pruning combined with foliar nutrition can improve fruit quality,increase yield,and ensure the continuous bountiful harvest of Myrica rubra Dongkui.

    2026, 67 (6):  1342-1348.  DOI: 10.16178/j.issn.0528-9017.20260244
    Abstract ( 54 )   HTML ( 1 )   PDF (484KB) ( 50 )  

    To evaluate fruit characteristics of the Morella nana resources in Guizhou,five fruit samples from the natural state were used as materials,and indicators such as single fruit weight,longitudinal and transverse diameters,fruit shape index,edible rate,color,and contents of soluble solids,total soluble sugar,titratable acid,total phenols,flavonoids,anthocyanins and vitamin C were measured and compared. The results showed that the single fruit weight of Morella nana was 3.30-5.57 g,and the edible rate was 75.05%-77.93%,both of which were significantly(p<0.05)lower than those of control(Huotan and Biqi);the anthocyanin content of the fruits was only 1.81-18.79 mg?kg-1,which was significantly lower than that of control,and the lightness value(L*)and yellow and blue value(b*)of color were significantly higher than those of control;the soluble solid content was 6.48%-8.52%,and the total soluble sugar content was 1.23%-2.27%,both of which were significantly lower than those of control;the titratable acid content was 4.31%-5.63%,and the the total phenol content was 9.42-11.17 mg?g-1,both of which were significantly higher than those of the control;the flavonoid content was 0.63-0.93 mg?g-1,with only one sample being significantly higher than control. The contents of fructose,glucose and sucrose contents were 0.99-2.42 mg?g-1,1.08-2.24 mg?g-1,and 2.32-5.92 mg?g-1,respectively,all of which were significantly lower than those of control;the contents of citric acid,malic acid and vitamin C contents were 30.68-40.55 mg?g-1,1.96-3.47 mg?g-1,and 0.15-0.24 mg?g-1,respectively,all of which were significantly higher than those of control. Therefore,the main characteristics of Morella nana fruits in the natural state are low sugar,low anthocyanin and high citric acid content. This study preliminarily reveals the fruit quality characteristics of Morella nana and provides a theoretical basis for the later selection of excellent strains and the development of functional foods.

    Elucidating the regulatory effects of potassium-solubilizing bacteria on the fruit quality of Chinese bayberry can provide theoretical basis and technical support for the development of novel functional microbial agents. In this study,using Dongkui Chinese bayberry as the test material,root irrigation experiments were conducted with two potassium-solubilizing bacterial strains(Gottfriedia sp. G1 and Priestia sp. P1)after flowering to investigate their effects on fruit appearance quality,sugar and acid components,and nutritional composition. The results showed that compared with the control,the two strains significantly (p<0.05) increased the soluble solids content of the fruit by 1.58 and 1.17 percent point,respectively,and significantly increased the contents of total soluble sugar,sucrose,and glucose. Meanwhile,the two strains significantly reduced the titratable acidity by 0.37 and 0.24 percentage points,respectively. Strain G1 exhibited a more pronounced effect on reducing citric acid and malic acid,resulting in a 57.6% increase in the sugar-to-acid ratio. In terms of nutritional composition,both strains significantly increased the total flavonoid content in the fruit. Strain G1 significantly increased the free amino acid content,whereas strain P1 significantly decreased it. Furthermore,the two strains had no significant effects on single fruit weight,transverse and longitudinal diameters,firmness,or coloration. In conclusion,Gottfriedia sp. G1 is a promising novel strain with the potential to enhance both the flavor and nutritional quality of Chinese bayberry.

    2026, 67 (6):  1355-1359.  DOI: 10.16178/j.issn.0528-9017.20250480
    Abstract ( 36 )   HTML ( 1 )   PDF (434KB) ( 52 )  

    In order to optimize the existing cultivation techniques for Myrica rubra,this study used Biqizhong Myrica rubra as the test material to systematically compare the effects of greenhouse mulching with film,ground mulching with weed-control fabric,reflective film,and geotextile on the micro-environment and economic traits of Myrica rubra. The results showed that greenhouse mulching with film increased air and soil temperature,while reduced air and soil humidity. Ground mulching with geotextile decreased soil temperature and humidity. The highest commercial fruit rate of Myrica rubra was 80.46% under greenhouse mulching with film,followed by ground mulching with geotextile and reflective film,both significantly (p<0.05) higher than 61.72% in open-field cultivation. Compared with open-field cultivation,ground mulching with geotextile significantly improved fruit hardness,soluble solids content,and solid acid ratio. Considering the costs of different mulching methods,geotextile has low cost,solid and durable properties. Ground mulching with geotextile enhanced the commercial fruit rate of Myrica rubra, and its fruit quality was significantly better than other treatments,making it a key technical measure for open-field cultivation of Myrica rubra.

    NI Xiaojun, LIANG Senmiao
    2026, 67 (6):  1360-1365.  DOI: 10.16178/j.issn.0528-9017.20250872
    Abstract ( 33 )   HTML ( 1 )   PDF (437KB) ( 51 )  

    Taking the Biqi variety of bayberry in mountainous facilities as the test object,a 0.66 hm2 integral multi-span arched greenhouse was vertically divided by plastic film into three(upper,middle and lower)or two(upper and lower)individual greenhouses,thereby changing the internal microclimate and achieving the goals of increasing yield,improving quality,and enhancing benefits. The results shows that the film partition is conducive to increasing the temperature and relative humidity of individual greenhouses. Specifically,compared with the non-partitioned treatment(CK),the temperature and humidity in the upper individual greenhouse can be raised by 1.2-7.8 ℃ and 0.8-12.4 percentage points,respectively. The maturity period is advanced by 5 to 8 days,and the harvest and supply period is extended by at least 1 to 2 days. Compared with CK,the single fruit weight of the film-partitioned treatment significantly(p<0.05)increased by 14.26%-17.63%,and the soluble solid content significantly increased by 1.26-2.35 percentage points. For the film-partitioned treatments,intrinsic qualities such as total sugar,flavonoids,and vitamin C contents were significantly improved. In the treatment divided into three individual greenhouses,the contents of these three components were 119.38 mg·g-1,0.95 mg·g-1 and 295.37 μg·g-1,respectively,which were 31.17%,26.67% and 27.76% higher than those in CK. Total acid decreased by 21.09%-22.61%. There was no significant difference in average yield between the film-partitioned treatments and CK,while the commercial fruit rate and premium fruit rate were 85.81%-90.25% and 66.55%-72.34%,respectively,which were significantly higher than those of CK by 10.14-14.58 percentage points and 12.86-18.65 percentage points. The output value of the film partition treatments was 777 800-791 900 yuan·hm-2,which was 43.11%-45.70% significantly higher than that of CK. The film partition of facilities for mountain bayberry production is simple,resulting in stable yield,excellent quality,and high benefits,thereby making it suitable for promotion in mountainous areas.

    ZHANG Jianbin, WU Yuyong, YING Zhengzheng, SUN Li, ZHANG Shuwen, YANG Han, LI Jiasheng, YU Qiaomei
    2026, 67 (6):  1371-1377.  DOI: 10.16178/j.issn.0528-9017.20260330
    Abstract ( 46 )   HTML ( 0 )   PDF (516KB) ( 56 )  

    To investigate the effects of Rhodobacter sphaeroides metabolites on fruit quality of Chinese bayberry,Myrica rubra Dongkui was used as the experimental material. The concentrated metabolites diluted 50-,100-,and 200- fold were applied via root irrigation during the fruit expansion stage,with water treatment as the control. The effects of each treatment on spring shoot growth and fruit quality of Chinese bayberry were compared and analyzed,and the active components in the metabolites were detected using non-targeted metabolomics and hormone quantitative analysis. The results showed that compared with the control,none of the treatments significantly affected spring shoot length,spring shoot diameter,or leaf SPAD value,but they significantly(p<0.05)increased leaf thickness and single fruit weight. Among them,the 50-fold and 200-fold dilution treatments increased single fruit weight by 35.64% and 38.70%,respectively. Regarding fruit quality,all treatments significantly increased soluble solids content,with the 100-fold dilution treatment showing the greatest increase(2.11 percentage points). The 200-fold dilution treatment significantly increased total sugar content,while the 50-fold dilution treatment significantly reduced titratable acid content,thereby significantly increasing the sugar-acid ratio. In addition,the 100-fold dilution treatment significantly increased total flavonoid content in fruit by 45.83%. Metabolite analysis revealed that the metabolites of Rhodobacter sphaeroides contained γ-aminobutyric acid(0.90 μg·mL-1)and relatively high concentrations of auxins(e.g.,indolepropionic acid at 79.33 ng·mL-1). In conclusion,the metabolites of Rhodobacter sphaeroides can synergistically improve the flavor and nutritional quality of Chinese bayberry by regulating the sugar-acid metabolic network and promoting the accumulation of functional components. This effect may be related to the synergistic regulation of γ-aminobutyric acid and auxins present in the metabolites. This study provides a theoretical basis and practical reference for the application of microbial metabolites in high-quality cultivation of Chinese bayberry.

    Abstract ( 36 )   HTML ( 0 )   PDF (1899KB) ( 52 )  

    To implement effective green control measures for fruit flies in Chinese bayberry,a study was conducted from May to July 2025 in an open-air Chinese bayberry orchard in Chashan,Ouhai District,Wenzhou City,Zhejiang Province. The field trapping effects of four attractants(homemade sugar-vinegar liquid,HZ,QZ,ZJ)and five types of traps(wide-mouth bottle with black cap,wide-mouth bottle with yellow cap,mineral water bottle-type,egg-type,and cup-type)on fruit flies were compared. The results showed that the primary fruit fly species in the Chashan Chinese bayberry orchard were Drosophila melanogaster and Drosophila suzukii. In the comparison of attractants,the total trapping numbers of fruit flies ranked as follows:homemade sugar-vinegar liquid>HZ>ZJ>QZ. The homemade sugar-vinegar liquid achieved the highest total trapping numbers for both D. melanogaster and D. suzukii. In the comparison of traps,the two wide-mouth bottle-type traps captured more fruit flies than the other three types. The trapping effectiveness for D. melanogaster was wide-mouth bottle with black cap>wide-mouth bottle with yellow cap>mineral water bottle-type>egg-type>cup-type. For D. suzukii,the trapping effectiveness was wide-mouth bottle with yellow cap>wide-mouth bottle with black cap>egg-type>mineral water bottle-type>cup-type. In summary,the homemade sugar-vinegar liquid demonstrated excellent trapping performance against fruit flies and was cost-effective,making it a viable effective attractant. The wide-mouth bottle-type traps(with either black or yellow caps)exhibited superior trapping capabilities compared with other types. It was recommended that Chinese bayberry orchards in the Wenzhou region adopt the combination of "homemade sugar-vinegar liquid + wide-mouth bottle-type trap" for green control of fruit flies,with the option to adjust the trap type based on the occurrence patterns of different fruit fly species.

    Abstract ( 34 )   HTML ( 0 )   PDF (570KB) ( 54 )  

    The Chinese bayberry industry is critically constrained by a harvest peak which coincides with the plum-rain season,resulting in severe pre-harvest losses(fruit cracking,drop and decay),fruit-fly infestation and high post-harvest wastage. Protected cultivation has emerged as a strategy to mitigate these issues through environmental control. This review systematically synthesized recent advances in Chinese bayberry protected cultivation,detailing the technical features and field performance of four main cultivation models:insect-proof netting,rain-shelter,forcing,and delaying cultivation. The dynamics of temperature,humidity,and light inside facilities were systematically examined. Their regulatory mechanisms on tree photosynthesis,growth,development,fruit quality and yield were elucidated. Current challenges,including high implementation costs,suboptimal management efficiency,and significant energy consumption,were discussed. Future research directions were proposed,such as deciphering plant-environment interactions,developing cost-effective and intelligent equipment,establishing precision predictive models,and breeding adapted cultivars. This review aims to provide a scientific basis for enhancing the productivity and sustainability of the Chinese bayberry industry.

    YANG Haiqin, YE Tingyun, HU Zefan, MA Liya, CHEN Zhaoming
    2026, 67 (6):  1438-1442.  DOI: 10.16178/j.issn.0528-9017.20250318
    Abstract ( 33 )   HTML ( 0 )   PDF (435KB) ( 50 )  

    A field experiment was conducted to investigate the effects of urea side-deep application on the yield and nitrogen use efficiency of double-season rice,and to provide a theoretical basis for efficient nitrogen fertilizer utilization in double-season rice production in southern Zhejiang Province. Four treatments were established:1)no nitrogen fertilizer(CK);2)conventional fertilization(CF);3)urea side-deep application(UD1);4)urea side-deep application with 10% nitrogen reduction(UD2). The results showed that compared with the CK treatment,nitrogen fertilization significantly (p<0.05)increased the yield of early-season rice and late-season rice by 31.7%-41.6% and 42.9%-47.9%,respectively. Compared with the CF treatment,urea side-deep application significantly increased the yield of early-season rice,while no significant difference in double-season rice yield was observed between the UD1 and UD2 treatments. Under urea side-deep application treatments,both grain nitrogen uptake and total nitrogen uptake of early-season and late-season rice were significantly higher than those under the CF treatment. Compared with the CF treatment,urea side-deep application significantly increased the apparent nitrogen use efficiency and nitrogen contribution rate of early-season rice,as well as the apparent nitrogen use efficiency of late-season rice. In addition,the UD2 treatment significantly increased the agronomic efficiency and partial factor productivity of nitrogen fertilizer for early-season rice,and the partial factor productivity of nitrogen fertilizer for late-season rice. Therefore,the adoption of urea side-deep fertilization technology in double-season rice production in southern Zhejiang Province can achieve the goals of high and stable rice yield and efficient nitrogen fertilizer utilization.

    Abstract ( 32 )   HTML ( 0 )   PDF (1536KB) ( 48 )  

    Currently,tobacco variety breeding primarily focuses on macro-level aspects such as agronomic traits,whereas the flavor characteristics of cigar tobacco leaves depend on the accumulation levels of metabolites during the early growth stage and their subsequent transformation during post-harvest processing. Therefore,breeding cigar tobacco varieties with abundant metabolite accumulation and superior agronomic traits is of paramount importance. This study employed derivatized gas chromatography-mass spectrometry (GC-MS) and headspace-solid phase microextraction-gas chromatography-mass spectrometry(HS-SPME-GC-MS)techniques to analyze major agronomic traits and detect volatile and aroma-contributing metabolites in nine cigar tobacco varieties cultivated in Xuancheng,Anhui Province. Differential metabolites were identified for subsequent metabolic pathway analysis. The results demonstrated that T11 exhibited the best agronomic traits. Metabolic profiling revealed that 63.0% of differential metabolites were upregulated in T11,with these upregulated metabolites correlating positively with tobacco aroma,flavor profile,and smoking quality. In summary,T11 not only demonstrates outstanding agronomic characteristics but also possesses a richer repertoire of beneficial metabolites,indicating its potential for developing high-yield and premium-quality cigar tobacco varieties.

    Abstract ( 48 )   HTML ( 0 )   PDF (446KB) ( 47 )  

    To explore the optimal cultivation measures for one-time harvest of upper leaves of tobacco variety NX212,this study conducted a three-factor three-level orthogonal experiment on leaf retention number,nitrogen application rate,and planting density in purple soil in Nanxiong City,Guangdong Province. The results demonstrated that planting density had the biggest impact on agronomic traits and appearance quality. The planting density of 1 000 plants per 667 m2 achieved optimal agronomic traits and appearance quality of tobacco leaves. Nitrogen application rate showed the strongest influence on chemical composition,with nicotine content,potassium content,and nitrogen-to-nicotine ratio reaching peak values at a nitrogen application rate of 180 kg·hm-2. Leaf retention number had the biggest impact on sensory quality. With an increase in leaf retention number,the scores for tobacco aroma,aftertaste,off-flavors,irritancy,and overall sensory quality evaluation exhibited a trend of initial decline followed by improvement. The optimal sensory quality was achieved when the leaf retention number reached 19. In summary,the three factors influencing the comprehensive quality of tobacco leaves followed this order of importance:nitrogen application rate> leaf retention number> planting density. Furthermore,based on range analysis,the optimal cultivation measures for one-time harvest of upper leaves of tobacco variety NX212 grown in purple soil in Nanxiong,Shaoguan include:planting 1 000 plants per 667 m2,applying 180 kg·hm-2 of nitrogen,and retaining 19 leaves per plant. This study provides crucial support for developing integrated cultivation strategies for one-time harvest in Guangdong's flue-cured tobacco production areas.

    This study aimed to investigate the effects of nitrogen application rate and planting density on seed oil yield and fatty acid composition of flue-cured tobacco Dashubazhiba,providing cultivation technical references for reducing the cost of its seed oil. A split-plot design was adopted,and the agronomic traits,seed yield traits,seed oil yield,and fatty acid composition of the seeds were compared under three nitrogen application rates(90.0,135.0,180.0 kg·hm-2)and three planting densities(18 180,22 230,27 780 plants per hectare). The results showed that the agronomic traits of Dashubazhiba were affected by nitrogen application rate,while seed yield and seed oil yield increased with increasing nitrogen application rate and planting density. The fatty acid composition of seed oil remained consistent across different treatments,but their contents showed slight variations. To obtain high-yield and high-quality seed oil of Dashubazhiba,the optimal nitrogen application rate was 180.0 kg·hm-2 and planting density was 27 780 plants per hectare. Under these conditions,seed yield reached 2 325.15 kg·hm-2,seed oil yield reached 962.60 kg·hm-2,and the contents of total fatty acids,monounsaturated fatty acids,polyunsaturated fatty acids,linoleic acid,and oleic acid were all at relatively high levels.

    Abstract ( 27 )   HTML ( 0 )   PDF (452KB) ( 46 )  

    Irregular tobacco-wheat intercropping adversely affects tobacco growth and leaf quality. To promote the coordinated development of integrated grain and tobacco production and further improve tobacco quality,a technical regulation for tobacco-wheat relay intercropping in central Henan Province has been developed based on scientific research projects. This regulation emphasizes tobacco as the primary crop,aims to enhance leaf quality,and specifies key aspects including spatio-temporal crop arrangement,variety selection,and corresponding cultivation techniques for tobacco. Demonstration results from seven sites in major tobacco-growing counties of central Henan Province showed that this regulation improves tobacco growth,reduces the incidence of major diseases,and enhances yield stability. The appearance quality,chemical composition,and sensory quality of the tobacco leaves were generally comparable to or approached those of monocropped tobacco,and were significantly better than those under traditional local intercropping practices. Compared with monocropped tobacco,the comprehensive output value increased by 1 106.7 yuan per 667 m2,with a net income increase of 709.4 yuan per 667 m2. Compared with traditional local intercropping,the comprehensive output value increased by 409.4 yuan per 667 m2,with a net income increase of 447.9 yuan per 667 m2. The application of this technical regulation serves as a demonstration model for promoting tobacco quality improvement in tobacco-wheat intercropping systems within integrated grain and tobacco production.

    Abstract ( 36 )   HTML ( 0 )   PDF (1097KB) ( 47 )  

    To clarify the characteristics of dry matter accumulation and the patterns of nitrogen,phosphorus,and potassium uptake and distribution in a sorghum-rapeseed rotation system,and to provide a theoretical basis for precision fertilization,a field positioning experiment was conducted from September 2020 to August 2022. Whole-plant sampling was performed at key growth stages of sorghum and rapeseed to determine dry matter accumulation and nitrogen,phosphorus,and potassium contents in different organs. The results showed that dry matter accumulation in both sorghum and rapeseed followed a "slow then fast" pattern. At maturity of sorghum,dry matter accumulation ranked as grain > stem and leaf > root;at maturity of rapeseed,dry matter accumulation ranked as stem and leaf > grain > pod shell > root. Nutrient uptake exhibited significant stage specificity:for sorghum,the critical period for phosphorus and potassium uptake was 39-64 d(accounting for 67.0% and 57.7% of demand,respectively),and the core period for nitrogen uptake was 65-100 d(accounting for 54.2% of demand);for rapeseed,the demand for phosphorus and potassium both exceeded 30% during 119-148 d,and nitrogen demand reached 49.7% during the mature stage(168-217 d). In the sorghum-rapeseed rotation system,the nitrogen,phosphorus,and potassium required for grain production were 35,11,and 46 g·kg-1 in average,respectively,among which sorghum grain accounted for 24,7,and 31 g·kg-1,and rapeseed grain accounted for 45,15,and 60 g·kg-1. This study clarifies the nutrient demand characteristics at each growth stage of the sorghum-rapeseed rotation system,providing data support for scientific fertilization in this system.

    Abstract ( 32 )   HTML ( 1 )   PDF (387KB) ( 49 )  

    This research was carried out to ensure the quality and safety of strawberry,explore new ways of green prevention and control in strawberry cultivation,improve the yield and quality of strawberry,and promote the efficient and healthy development of the strawberry industry. In this experiment, strawberry variety Yuexiu were used as the test materials,and two plant immune elicitors,Shouchengwang and Ainuosen,were introduced. By comparing the application of plant immune elicitors with that of conventional fertilizers,the growth indicators,fruit characteristics of strawberries,as well as their different impacts on strawberry disease resistance,were analyzed. The experimental results showed that,compared with conventional fertilization,the two plant immune elicitors could,to a certain extent,promote growth,improve taste and increase yield. Their performance in strawberry pest and disease resistance was similar to that of conventional fertilization. When the two plant immune elicitors were compared,Shouchengwang was more effective in increasing yield,while Ainuosen was more effective in improving taste. This proves that the introduction of plant immune elicitors in the strawberry cultivation process,combined with the reduction of conventional fertilizers and the adoption of green prevention and control technologies,that is,the production mode of "fertilizer reduction + plant immune elicitor + green prevention and control technologies(traps,color plates,predatory mites,etc.)" can,to a certain extent,achieve the effects of fertilizer reduction,environmental friendliness,yield increase and quality improvement,as well as green safety.

    2026, 67 (6):  1539-1542.  DOI: 10.16178/j.issn.0528-9017.20250966
    Abstract ( 33 )   HTML ( 1 )   PDF (388KB) ( 51 )  

    In this experiment,herbicides including 36% diuron diflufenican suspension concentrate(Fengqu),50% isoproturon suspension concentrate(Sumailong),3.6% mesosulfuron-methyl & iodosulfuron-methyl sodium water-dispersible granule(Kuoshima),and 55% diflufenican & isoproturon suspension concentrate (Jichu)were selected for weed control in barley fields to evaluate their efficacy and safety. The results showed that Jichu exhibited the best control effect against the weeds of Gramineae,with plant control efficacy and fresh weight control efficacy reaching 67.9% and 75.5%,respectively. Moreover,it was safe for barley and increased yield by 8.9%. Although the mixed treatment of Fengqu and Sumailong as well as the Kuoshima treatment showed good weed control efficacy,both caused phytotoxicity and resulted in yield reduction. The mixed treatment of pinoxaden and carfentrazone-ethyl and the single application of isoproturon showed poor control efficacy. This study provides a basis for selecting appropriate herbicides for scientific weed control in barley fields in the Jiangsu-Zhejiang region.

    BAI Peixian, SHI Daliang, AO Cun, ZHAO Yun, CUI Hongchun
    2026, 67 (6):  1543-1550.  DOI: 10.16178/j.issn.0528-9017.20250911
    Abstract ( 30 )   HTML ( 0 )   PDF (516KB) ( 53 )  

    The high maturity and poor uniformity of machine-harvested tea leaves pose considerable challenges to the production of high-quality black tea,making process optimization crucial. In this study,13 tea samples were prepared from machine-harvested fresh leaves by using different processing parameters,including withering method,rolling duration,fermentation conditions,drying method,and fine cutting treatment. The sensory quality and key biochemical components were systematically evaluated. The results show that fine cutting treatment improves sensory scores and promotes the dissolution of soluble components. Shaking withering improves aroma quality,rolling for 1.5 h gives the best comprehensive quality,and fermentation at 30 ℃ for 3 h produces the optimal sensory quality. Charcoal baking outperforms hot-air drying and electric drying in all evaluated indices. An optimized processing system centered on shaking withering,rolling for 1.5 h,fine cutting treatment,and fermentation at 30 ℃ for 3 h is established. Considering both quality and cost factors,hot-air drying is recommended for continuous production in practical application,as it can achieve near-optimal comprehensive quality at a lower cost. This study provides a reliable technical basis for improving the quality of black tea from machine-harvested leaves.

    2026, 67 (6):  1551-1555.  DOI: 10.16178/j.issn.0528-9017.20250776
    Abstract ( 33 )   HTML ( 2 )   PDF (425KB) ( 52 )  

    The experiment aims to investigate the effects of Pomacea canaliculata on growth performance,carcass quality,and meat quality of Shaoxing ducks. 240 5-week-old Shaoxing ducks were selected and randomly divided into 2 groups,with 4 replicates in each group. The control group was fed with a corn-soybean meal basic diet,while the experimental group contained 3% chilled Pomacea canaliculata(crushed with shell,calculated as air-dried matter). The energy and protein content of the two diets were the same. The results showed that compared with the control group,the final weight and total weight gain of Shaoxing ducks in the experimental group were significantly(p<0.05)increased by 4.4% and 11.3%,respectively,and the feed-to-weight ratio was significantly reduced by 10.0%. Compared with the control,the apparent digestibility of crude protein,crude fiber and calcium in the experimental group was increased by 3.64,4.17,and 2.57 percentage points,respectively. The eviscerated yield rate,leg muscle rate,chest muscle rate and abdominal fat rate of Shaoxing ducks in the experimental group were significantly increased by 2.8,0.4,1.1,and 0.8 percentage points,respectively. Meanwhile,the muscle redness value a* and lightness value L* were significantly higher than those in the control group. The experiment results showed that the addition of chilled Pomacea canaliculata to the feed could significantly improve the growth performance,feed absorption and utilization rate,carcass quality and meat color of Shaoxing ducks.

    Analysis of agricultural green total factor productivity in the Yangtze River Economic Belt:considering data factor input
    FENG Dengkui
    2026, 67 (6):  1556-1562.  DOI: 10.16178/j.issn.0528-9017.20250199
    Abstract ( 30 )   HTML ( 0 )   PDF (952KB) ( 51 )  

    The development of data factor has injected new vitality into agricultural green development,promoted agricultural innovation,and facilitated the process of agricultural modernization. Based on panel data of 11 provinces(municipalities)in the Yangtze River Economic Belt from 2013 to 2022,this paper introduces data factor as a new input variable and adopts the input-oriented super-efficiency SBM-GML model to measure agricultural green total factor productivity(GTFP)and analyze its spatiotemporal evolution characteristics. The findings show that the agricultural GTFP in the Yangtze River Economic Belt grew at an average annual rate of 3.7%,with technological progress being the main driving factor,while regional heterogeneity in technical efficiency and scale efficiency is significant. Spatially,it presents a complex pattern characterized by “high technological level in the east and low in the west,scale expansion in the west and stagnation in the east,and efficiency depression in the central region”. Guizhou,Shanghai,and Chongqing ranked the top three,while Jiangxi was the only region with negative growth. The input of data factor has strengthened the role of technological progress in improving agricultural GTFP. This study provides empirical evidence for the coordinated development of agricultural green transformation and data factor in the Yangtze River Economic Belt,and offers policy implications for optimizing regional resource allocation and promoting the deep integration of data factor with agriculture.
