Based on the supervision and sampling inspection data of 3 507 crop seed batches in Zhejiang Province during the 14 th Five-Year Plan，this paper analyzed three quality indicators：purity，germination rate and moisture content. The results indicated that the overall qualification rate of crop seed quality in the province remained between 92.6% and 96.9% during this period，showing a steady improvement compared with the 13 th Five-Year Plan period. Specifically，the average five-year qualification rate for grain and oil crop seeds was 98.3%，for vegetable and melon crop seeds was 89.2%. Excessive moisture content was the primary limiting factor for unqualified crop seeds，followed by germination rate. On the basis of elucidating the current quality status and its causes，this paper proposed improvement strategies from four aspects：strengthening policy support and safeguards，enhancing seed quality testing capabilities，tightening seed market supervision，and promoting the expansion and strengthening of enterprises. This study aimed to provide a reference for seed quality supervision and the high-quality development of the seed industry during the 15 th Five-Year Plan period.

Effects of seedling age and planting density on the growth period and yield of indica-japonica hybrid rice Chunyou 801 under machined-transplanting cultivation YI Jianqun, DONG Zhiyun, LI Yun, LI Chengyong, XU Nanchang, WANG Honghang 2026, 67 (7):  1601-1606.  DOI: 10.16178/j.issn.0528-9017.20250278 Abstract ( 39 )   HTML ( 1 )   PDF (432KB) ( 124 )   To investigate the effects of different seedling ages and planting densities on the growth period and yield of Chunyou 801，seedling age and planting density tests were conducted. The seedling age test employed a split-plot design with two factors，using three sowing periods，June 25（A1），June 30（A2），and July 5（A3），as the main treatments and three transplanting periods，July 20（B1），July 25（B2），and July 30（B3），as the sub-treatments. The single factor randomized block design was used in planting density test with four cultivation densities：27.8×104 hills per hectare（C1），23.8×104 hills per hectare（C2），20.8×104 hills per hectare（C3）and 18.5×104 hills per hectare（C4）. The results showed that seedling age had a significantly（p0.05）effect on whole growth period and yield under machined-transplanting cultivation. When the sowing period was the same，as the seedling age increased，the days from sowing to heading period prolonged，the days from heading to maturity period shortened，and the whole growth period prolonged. The yield was the highest at 25 d seedling age. The planting density had no significant effect on the growth period. There was no significant difference among treatments in 2021. However，in 2022，the C1 treatment had the highest yield and was significantly higher than the C4 treatment. Overall，Chunyou 801 is suitable for planting as double-cropping late rice in Quzhou. The appropriate seedling age of mechanical transplanting is 25 d，and the planting density is 27.8×104 hills per hectare，which is easy to obtain high yield.

Influence of rice variety and water-fertilizer management combination on rice yield and quality JIANG-XU Yuxuan, ZHANG Junpeng, NI Di'an, SUN Huifeng, ZHANG Jining, WANG Cong, JIANG Zheng, ZHANG Xianxian, ZHOU Sheng 2026, 67 (7):  1612-1618.  DOI: 10.16178/j.issn.0528-9017.20250485 Abstract ( 42 )   HTML ( 2 )   PDF (504KB) ( 96 )   To investigate the comprehensive effects of different combinations of agronomic practices on rice yield and quality，a multifactorial randomized block experiment was conducted using rice varieties，water-saving irrigation，and fertilizer management as factors. Water-saving drought-resistant rice and conventional flooded rice were used as experimental materials，with two irrigation methods，conventional flooding and water-saving irrigation，being established，combined with organic fertilizer application. The study examined rice yield and quality under different combinations. The results indicated that the yield of water-saving drought-resistant rice under water-saving irrigation was comparable to that of traditional rice under conventional flooding（straw returning combined with nitrogen fertilizer application）. Moreover，water-saving drought-resistant rice enhanced the milling quality of rice，including brown rice rate，milled rice rate，and head rice rate. However，the effects on appearance and eating quality of rice were inconsistent. Specifically，protein content was higher，while amylose content was significantly （p0.05） lower，which had a certain impact on cooking quality of rice. Additionally，the cultivation model combining water-saving irrigation，organic fertilizer application，and water-saving drought-resistant rice varieties could maintain relatively high rice yields while improving milling quality. Future research should further optimize the combinations of different agronomic practices（e.g.，irrigation methods and fertilization strategies）to achieve synergistic improvement in both rice yield and quality，thereby providing a scientific basis for green and high-quality development of agriculture.

Performance of conventional japonica rice in demonstration trials and under different cultivation methods ZHANG Qiyan, MENG Huabing, ZHOU Jinting, SUN Li 2026, 67 (7):  1619-1624.  DOI: 10.16178/j.issn.0528-9017.20250283 Abstract ( 40 )   HTML ( 0 )   PDF (415KB) ( 92 )   To investigate the adaptability and advantages of different conventional japonica rice varieties，and to provide a reference for the promotion and planting of different varieties in Wuxing District，this study analyzed the planting performance of 17 conventional japonica rice varieties in Wuxing District from the perspectives of growth period，effective panicle number，filled grain number per panicle，thousand-grain weight，theoretical yield，measured yield，and resistance. To further explore the trait performance and yield characteristics under different cultivation modes，this study used Zhejing 100 as the test variety and carried out three cultivation trials：mechanical transplanting，hole seeding，and unmanned aerial vehicle（UAV）direct seeding. The results showed that varieties such as Zhejing 78 and Xiushui 134 exhibited good overall field performance，with characteristics such as high yield and strong lodging resistance，making them suitable for promotion in pursuit of yield improvement. Varieties such as Changxiangjing 1813，Nanjing 46，and Zhehexiang 2 showed moderate lodging resistance and yield performance but had better rice quality，requiring certain cultivation techniques and water and fertilizer management measures，and were suitable for farmers aiming to develop the high-quality rice market. Under the three cultivation modes，Zhejing 100 performed best in terms of yield，lodging resistance and other indicators under mechanical transplanting，worst under UAV direct seeding，and intermediate under hole seeding. The hole seeding mode is a relatively suitable cultivation method for rice farmers who cannot meet the equipment and facility requirements for seedling raising and mechanical transplanting.

Effects of spraying gibberellin（GA）and epibrassinolide（epi-BR）on flowering time of japonica male sterile lines in three-line hybrid rice seed production SHI Yang, NI Suhong, SHAN Chengyan, LUO Yechong, DING Zhengquan, PAN Yueyun, HUANG Haixiang, SHAO Jie 2026, 67 (7):  1625-1631.  DOI: 10.16178/j.issn.0528-9017.20260301 Abstract ( 33 )   HTML ( 1 )   PDF (535KB) ( 89 )   To clarify the regulatory effects of gibberellin（GA）and its combination with epibrassinolide（epi-BR）on floret opening time traits of japonica rice male sterile lines，and to alleviate the problem of floret opening time asynchrony in indica-japonica hybrid rice seed production，a field experiment was conducted at the heading stage using the long-grain japonica rice male sterile line Jiahe 112A as material. The experiment included treatments with different GA mass concentrations，spraying time，and GA/epi-BR mixing ratios，and the regulatory patterns of these factors on floret opening time and durations of different flowering stages were systematically analyzed. The results showed that exogenous GA significantly advanced floret opening time in a concentration-dependent manner，with the 0.100 mg·L-1 treatment exhibiting the optimal effect. Meanwhile，GA significantly shortened the early floret opening process and total flowering duration，but had no significant effect on the late floret opening process. Spraying time significantly affected the regulatory effect：spraying GA at 17：00 on the day before investigation showed a significantly stronger effect on advancing floret opening time than morning treatments on the day of investigation，while morning spraying was more conducive to shortening the total flowering duration. The combination of GA and epi-BR exhibited a synergistic effect；the optimal promoting effect was achieved when GA and epi-BR were mixed at a mass concentration ratio of 3∶1（with GA at 0.100 mg·L-1 and epi-BR at 0.033 mg·L-1），which was significantly superior to both the single GA treatment and the control，and the effect was optimal when sprayed at 17：00 on the day before investigation. Collectively，spraying the GA/epi-BR mixture prepared at a mass concentration ratio of 3∶1 at 17：00 on the day before investigation is the optimal regulatory strategy to achieve efficient and synchronous advancement of floret opening time for Jiahe 112A. This study provides an innovative and promising technical strategy for addressing floret opening time asynchrony in indica-japonica hybrid rice seed production.

The main plots consisted of four planting densities：5 500 plants per 667 m2（D1），6 500 plants per 667 m2（D2），7 500 plants per 667 m2（D3），8 500 plants per 667 m2（D4）．The subplots comprised three fertilizer application rates：15 kg per 667 m2 of compound fertilizer as base fertilizer and 10 kg per 667 m2 of compound fertilizer as topdressing（M1），15 kg per 667 m2 of compound fertilizer as base fertilizer and 20 kg per 667 m2 of compound fertilizer as topdressing（M2），and 15 kg per 667 m2 of compound fertilizer as base fertilizer and 30 kg per 667 m2 of compound fertilizer as topdressing（M3）. Results showed that under different planting densities，the D2 treatment had the highest yield and was significantly （p0.05）higher than D3 treatment and D4 treatment. Under different fertilization application rates，the M3 treatment had the highest yield and was significantly higher than M1 treatment. Under the interaction between planting density and fertilizer application rates，the D2M2 treatment had the highest yield，which reached 597.50 kg per 667 m2 and was significantly or highly significantly （p0.01） higher than other treatments，except that the D2M3 treatment showed no significant differences compared with D2M2. Therefore，the proper planting density of Huangjin Xiaoyumi was 6 500 plants per 667 m2. Under this density，applying 15 kg compound fertilizer as base fertilizer and 20-30 kg compound fertilizer per 667 m2 as topdressing could obtain a better yield.

The results showed that Ascomycota was the dominant phylum in all crop rotations. The relative abundances of Mortierellomycota，Mortierellomycetes，and Humicola in healthy plants were higher than those in diseased plants across all crop rotations，indicating that the soil fungal community abundance of Baitiao Codonopsis pilosula plants with root rot showed a decreasing trend. FUNGuild predicted the nutritional types and functional groups of rhizosphere soil fungi，revealing that the relative abundance of plant pathogens in all crop rotations was consistently higher in diseased plants than in healthy plants. Comparing the incidence rate of all crop rotations，we found that the incidence rate of root rot of wheat-broad bean-Codonopsis pilosula was the lowest，followed by maize-wheat-Codonopsis pilosula. Overall，crop rotation of wheat-broad bean-Codonopsis pilosula can effectively reduce the incidence of root rot，which may be related to increasing soil microbial abundance.

Diagnosis of drought stress in lilies based on chlorophyll fluorescence parameters JIANG Yuanjun, YANG Yiping, FU Manman, WU Chao 2026, 67 (7):  1725-1733.  DOI: 10.16178/j.issn.0528-9017.20240944 Abstract ( 38 )   HTML ( 0 )   PDF (1036KB) ( 87 )   Water and photosynthesis are key factors regulating plant growth，and drought stress induces stomatal closure in leaves，thereby impairing plant photosynthetic performance. To clarify the changes in chlorophyll fluorescence parameters of lily ‘Sunderland’ under drought stress，this study analyzed chlorophyll fluorescence parameters under varying photosynthetically active radiations and temperatures，and calibrated the functional relationship between photosynthetic rate and chlorophyll fluorescence parameters. Additionally，data collected during drought stress and after stress relief were used to examine changes in chlorophyll fluorescence parameters before and after rewatering. The results showed that with an increase in photosynthetically active radiation，the quantum yield of chloroplast photosystem Ⅱ（PSⅡ） photochemistry（Φ2）exhibited a decreasing trend，while the quantum yield of regulated energy dissipation（ΦNPQ）showed an increasing trend. The quantum yield of non-regulated energy dissipation（ΦNO）remained essentially unchanged across different temperatures and was negatively correlated with ΦNPQ. Lily plants achieved the maximum Φ? when photosynthetically active radiation was 0. The coefficient of determination （R2） between predicted and actual values of Φ? was 0.95，with a relative root mean square error（rRMSE）of 3.15%. For the fraction of open PSII reaction centers（qL），the R2 was 0.86 and the rRMSE was 6.15%. For ΦNPQ，the R2 was 0.95 and the rRMSE was 9.58%. With increasing drought stress intensity，ΦNO and ΦNPQ increased，while the net photosynthetic rate at saturating light（Pn，max），Φ2，qL，and the maximum photochemical efficiency of PSII（Fv/Fm）decreased. Furthermore，the carbon assimilation capacity per electron（s）and dark respiration rate（Rd）were also reduced. After 10 days of rewatering，Pn，max and \Phi ? of lily plants under a soil water potential of -20 to -15 kPa were essentially consistent with those under -10 to -4 kPa. These findings provide a reference for evaluating the growth of lily under drought stress. Figures and Tables | References | Related Articles | Metrics

The results showed significant （p0.05） differences in biomass and growth indicators among provenances，revealing obvious geographical variation. However，there was no significant difference in the root-shoot ratio among provenances，indicating that Q. acutissima maintains a relatively stable biomass allocation pattern across different geographical environments. Regarding seed traits，seed length was the most conservative，while 100-seed weight showed substantial variation. Overall，the Yantai and Qingdao provenances exhibited better seedling growth performance；whereas the Laiwu provenance performed poorly in most growth indicators. These findings provide a scientific basis for selecting superior provenances and regionalized cultivation of Q. acutissima. Figures and Tables | References | Related Articles | Metrics

The results showed that O. sauteri feeding on eggs of M. separata，M. loreyi and M. brassicae could successfully complete the generation development. The total nymphal development durations of the three treatments were 12.72，13.08 and 13.19 d，respectively，with no significant difference among them. The adult acquisition rates reached 88.33%，86.67% and 88.33%，respectively，which were significantly （p0.05） higher than those in the treatments with A. segetum eggs（11.67%）and X. c-nigrum eggs（10.00%）. In terms of fecundity，O. sauteri fed on M. separata eggs had the the shortest pre-oviposition period（2.98 d）and the highest oviposition amount per female（98.25 eggs），and the longest female adult longevity（27.76 d）. Very few nymphs of O. sauteri feeding on A. segetum and X. c-nigrum eggs could complete emergence，which failed to meet the requirements for their normal growth and development.In conclusion，eggs of M. separata，M. loreyi and M. brassicae can all be used as suitable prey for large-scale artificial rearing of O. sauteri，among which M. separata eggs present the optimal rearing effect. M. loreyi and M. brassicae eggs have raw material advantages for large-scale breeding，and can be used as alternative prey for the industrial production of O. sauteri.

Effects of soybean meal reduction on performance and egg quality of intensive caged laying hens WANG Baiqing, SUN Yan, YAN Feifei, BIAN Sushu, QIAN Lisha, LIU Lijun, QIAN Dinghai 2026, 67 (7):  1752-1757.  DOI: 10.16178/j.issn.0528-9017.20250253 Abstract ( 41 )   HTML ( 0 )   PDF (472KB) ( 87 )   At present，the feed for laying hens in China mainly consists of corn and soybean meal. As a by-product of soybean oil extraction，soybean meal has a large price fluctuation，which has a negative impact on the livestock and poultry breeding in China. Therefore，seeking the diversification of energy feed and reducing the use of soybean meal will be an inevitable trend in the future development of laying hen feed. This experiment aims to study the effects of wheat replacing corn and reducing the amount of soybean meal on the production performance and egg quality of Hy-line Brown laying hens. The results showed that when wheat completely replaced corn and the amount of soybean meal was reduced from 25% to 15%，there were no significant differences in the laying rate，average egg weight and feed-to-egg ratio of laying hens. When wheat replaced corn and the amount of soybean meal was reduced to 18%，the average egg weight can be significantly （p0.05） increased. After wheat replaced corn，the egg quality indicators such as yolk ratio，albumen height and Haugh unit were significantly improved；however，there was no significant effect on eggshell strength and eggshell thickness. It can be seen that replacing corn with wheat and reducing the amount of soybean meal not only did not reduce the laying performance of laying hens，but also significantly enhanced some egg quality of laying hens. This experiment provided theoretical and practical support for the application of wheat in laying hen breeding and reducing the use of soybean meal，and also provided an alternative solution for the policy of reducing and replacing corn and soybean meal.

Regulatory effects of different fertilization methods on nitrogen and phosphorus loss via runoff in paddy fields XIE Qigan, HONG Qinghong 2026, 67 (7):  1758-1763.  DOI: 10.16178/j.issn.0528-9017.20250939 Abstract ( 40 )   HTML ( 2 )   PDF (896KB) ( 91 )   To explore optimal fertilization strategies for rice production and non-point source pollution control，a fixed-site experiment was conducted under an early rice-late rice rotation system in a paddy soil area of Wuyi County. Four treatments were established：conventional fertilization，key-factor optimization，integrated optimization，and a blank control. The results showed that cumulative rainfall during the experimental period was 1 406?mm，which induced 11 runoff events with a runoff coefficient of 0.10，indicating significant water retention capacity of the paddy field. The nitrogen and phosphorus inputs from rainfall were 1.67 and 0.024 kg per 667 m2，respectively. After fertilization，differences in nitrogen and phosphorus losses were observed among treatments. The conventional fertilization treatment exhibited the highest total nitrogen and total phosphorus losses（0.23 and 0.006 9 kg per 667 m2，respectively）. The key-factor optimization treatment，which applied stabilized compound fertilizer，reduced total nitrogen loss by 17.4% compared to the conventional fertilization treatment. The integrated optimization treatment，involving the combined application of commercial organic fertilizer and stabilized compound fertilizer，maintained total nitrogen loss at a level comparable to that of the key-factor optimization treatment，while reducing nitrate nitrogen loss by 33.3% compared to the conventional fertilization treatment and keeping phosphorus loss at a relatively low level. The study demonstrates that the combined application of organic manure and stabilized chemical fertilizers can effectively mitigate nitrogen and phosphorus losses via runoff，thereby providing technical support for non-point source pollution control in rice-growing regions of southern China.

Threshold response and synergistic driving mechanism of soil organic carbon to environmental factors in Jinyun County，Zhejiang Province LYU Yongjie, HAO Ruixin, CHEN Junhong, XU Mingxing, CHENG Min, MA Junwei, WU Shaohua 2026, 67 (7):  1775-1782.  DOI: 10.16178/j.issn.0528-9017.20260216 Abstract ( 33 )   HTML ( 0 )   PDF (623KB) ( 81 )   Soil organic carbon（SOC）responses to environmental factors are commonly nonlinear and threshold-dependent，yet most studies remain limited to importance ranking and fail to identify regulatory boundaries and triggering mechanisms，constraining precise carbon management. This article took the hilly area of Jinyun County，Zhejiang Province as an example，used soil sampling points and multiple environmental variables to construct a random forest model，and combined SHAP（SHapley Additive exPlanations）partial dependence diagram and sensitivity fitting curve to propose a "contribution-response consistency" criterion to identify the high-impact intervals of the main control factor，and constructed a comprehensive impact intensity index（SⅡ）to characterize the strength of the synergistic effect of multiple factors. The results revealed that SOC spatial heterogeneity was not driven by single factor continuous driving，but exhibited obvious interval control characteristics. Aspect（0 °-100 °），evapotranspiration（880-920 mm），ground surface temperature（17-19 ℃），and slope（0 °-10 °）form a sensitivity interval of SOC response. Significant （p0.05） SOC responses occurred only when multiple factors simultaneously fall within this interval，whereas single factor alone was insufficient to trigger variation. The SII further indicated SOC in hilly area was regulated by multi-factor threshold synergy rather than additive effects. This study revealed the environmental regulation boundary of SOC formation from the perspectives of interval and synergy，providing a theoretical basis for the transformation of carbon sequestration management in hilly areas from "factor optimization" to "condition matching".

Identification，cultivation characteristics of an isolated wild Taiwanofungus camphoratus strain and the capacity of producing asexual spores ZHANG Lu, KE Binrong, ZHENG Shizhong, WEI Qi, ZHANG Weirui, LIU Shengrong 2026, 67 (7):  1783-1788.  DOI: 10.16178/j.issn.0528-9017.20250378 Abstract ( 30 )   HTML ( 0 )   PDF (1724KB) ( 86 )   Taiwanofungus camphoratus is a precious medicinal fungus endemic in Taiwan，China. This study identified an isolated wild Taiwanofungus camphoratus strain and examined its mycelial growth characteristics under liquid culture conditions. Morphological and ITS（Internal Transcribed Spacer）phylogenetic analysis identified the strain Ac-NF2 as Taiwanofungus camphoratus. For strain Ac-NF2，the suitable single carbon source in liquid culture was maltose，while the optimal combined carbon source was a combination of glucose and maltose. The appropriate single nitrogen source was yeast extract，and the preferred combined nitrogen source was a combination of peptone and yeast extract. The optimal pH value of the medium was between 5 and 6，and the temperature range of 25 and 27 ℃ was desirable for the mycelial growth. The strain produced easily asexual spores in liquid cultures，and the density of asexual spores reached 3.2×107 mL-1. The present study not only broadened the germplasm source of Taiwanofungus camphoratus，but also provided reference for the application of this strain in liquid fermentation production of mycelium and active ingredients.

Effects of seeding rate and rhizobium inoculation on yield and soil fertility enhancement inChinese milk vetch（Astragalus sinicus L.） ZHOU Miao, CAI Wei, XU Jiezhang, LIU Xiaoxia, LIN Baoyi 2026, 67 (7):  1796-1800.  DOI: 10.16178/j.issn.0528-9017.20250719 Abstract ( 35 )   HTML ( 0 )   PDF (442KB) ( 92 )   Chinese milk vetch（Astragalus sinicus L.），as an important green manure crop in southern rice-growing regions，exhibits significant variations in yield and soil improvement effects under key agronomic practices such as seeding rate and rhizobium inoculation. Independent field experiments conducted in typical rice-growing areas of Zhejiang Province demonstrated that when the seeding rate was maintained within 1.5-2.5 kg per 667 m2，the fresh grass yield of Chinese milk vetch remained stable above 1 500 kg per 667 m2，with significant （p0.05） enhancements in soil organic matter，total nitrogen，available phosphorus，and available potassium contents. However，increasing the seeding rate to 2.5 kg per 667 m2 provided no additional yield benefits. Rhizobium inoculation significantly promoted plant growth and nutrient accumulation，increasing fresh grass yield by 18.97% and 28.24% for Zhejiang Ningbo Daqiao and Jiangxi Yujiang Daye varieties， respectively，while raising nodule numbers by 42.96% and 47.96%， respectively. The inoculated plants showed significantly improved nitrogen，phosphorus，and potassium contents，further enhancing soil fertility after incorporation. In conclusion，combining a seeding rate of 1.5-2.0 kg per 667 m2 with rhizobium inoculation was recommended for Chinese milk vetchproduction to achieve synergistic improvement in both yield and soil fertility，providing technical support for efficient green manure utilization in southern rice-growing regions.

Rhizosphere microbial community characteristics of perennial Hangbaishao in the genuine producing area JIN Yi, LI Haishen, SUN Jian, ZHOU Chaobin, JIANG Ling, HU Chunli, ZHAN Jianyong, WANG Zhi'an 2026, 67 (7):  1801-1811.  DOI: 10.16178/j.issn.0528-9017.20250201 Abstract ( 29 )   HTML ( 1 )   PDF (2119KB) ( 84 )   To investigate the changes in the composition and structure of soil bacteria，fungi，and archaea under different planting durations in the genuine producing area of Hangbaishao，and to screen for beneficial microbial strains in the rhizosphere of Hangbaishao in this area，rhizosphere soil samples of Hangbaishao aged 1，2，3，and 4 years were collected from Dongyang City，Zhejiang Province. Microbial community structure analysis was conducted to elucidate the microbial composition characteristics and succession patterns in the rhizosphere soil during Hangbaishao colonization. Functional predictions of the microbial communities were performed using the EggNOG，KEGG，and CAZy databases. The results showed that the microbial composition of Hangbaishao soil was dominated by bacteria（85.561%-91.680%），archaea（0.481%-2.804%），fungi（0.018%-0.030%），and viruses（0.022%-0.117%），with other microorganisms accounting for 7.516%-11.500%. As planting duration increased，some inferior microbial groups gradually disappeared，and microbial diversity decreased. The relative abundance of bacteria increased from 85.561% in the 1-year-old rhizosphere soil to 91.680% in the 4-year-old soil. The relative abundances of archaea and viruses declined from 2.804% and 0.117%（1-year-old）to 0.481% and 0.022%（4-year-old），respectively. The relative abundance of fungi first increased and then decreased，from 0.018%（1-year-old）to a peak of 0.030%（3-year-old），and then dropped to 0.024%（4-year-old）. Furthermore，CandidatusRokubacteria and Nitrospira were identified as signature taxa in the rhizosphere soil in the genuine producing area. These results indicate that with increasing planting duration in the genuine producing area of Hangbaishao，microbial diversity decreases，while characteristic taxa such as CandidatusRokubacteria and Nitrospira are recruited and enriched.

This paper focuses on the practical work of cultivated land quality monitoring in Zhejiang Province. Based on a special survey conducted in 11 prefecture-level cities across the province，it provides an in-depth analysis of the achievements and existing problems of the cultivated land quality monitoring system in Zhejiang Province，and proposes countermeasures and suggestions for optimal layout. The results show that the cultivated land quality monitoring system in Zhejiang Province is characterized by a relatively complete monitoring network and a sound management system，but also faces issues such as insufficient representativeness of some monitoring points and difficulties in long-term operation and maintenance. To address these problems，this paper proposes countermeasures including optimizing the layout of the cultivated land monitoring network，strictly controlling the quality of sample collection and testing，encouraging counties and districts to add long-term positioned monitoring functional areas for cultivated land quality，and strengthening the construction of a tiered professional talent team. These suggestions aim to provide scientific references for improving the accuracy and effectiveness of cultivated land quality monitoring in Zhejiang Province and consolidating the foundation of food security.

Effects of long-term different land use patterns on farmland soil ecosystem multifunctionality and microbial diversity RONG Zhizhuo, WU Chunyan, TANG Xiangyu 2026, 67 (7):  1816-1828.  DOI: 10.16178/j.issn.0528-9017.20250247 Abstract ( 37 )   HTML ( 2 )   PDF (2862KB) ( 88 )   To reveal the differences in ecosystem multifunctionality and microbial diversity among different land use patterns and provide scientific basis for farmland soil management and sustainable development，five types of farmland soils（orchard，cornfield，soybean field，greenhouse，and abandoned land）were selected as research objects. Soil physicochemical properties，enzyme activities，and microbial diversity were analyzed，and the differences in ecosystem multifunctionality and microbial diversity among different land use patterns were compared. The results showed that there were significant （p0.05）differences in soil ecosystem multifunctionality indicators among different land use patterns. Correlation analysis revealed that soil pH value，available nitrogen content，total nitrogen content，total phosphorus content，available phosphorus content，organic matter content，and the activities of β-glucosidase，N-acetyl-β-glucosaminidase，cellulase，polyphenol oxidase，and peroxidase were significantly correlated with ecosystem multifunctionality. Analysis of variance indicated that orchard soil had the highest ecosystem multifunctionality，whereas cornfield soil almost lost its ecosystem multifunctionality under the 75% threshold. High-throughput sequencing results showed that orchard soil had the highest bacterial diversity，and bacterial communities had a more significant impact on soil ecosystem multifunctionality than fungal communities in farmland soil ecosystems. In conclusion，protecting farmland soil bacterial diversity should be the core strategy for improving farmland soil ecosystem multifunctionality. The high ecosystem multifunctionality of orchard soil verifies the positive feedback mechanism of microbial diversity on ecosystem function，making it the most recommended land use pattern.
