Effect of morphological traits on weight traits of juvenile populations with two different shell colors in the white breeding line of Hyriopsis cumingii CHENG Xiaoling, ZHAO Weihua, ZHU Mingxing, ZHANG Genfang, LUO Yu 2025, 66 (8):  1809-1818.  DOI: 10.16178/j.issn.0528-9017.20250338 Abstract ( 42 )   HTML ( 13 )   PDF (3872KB) ( 87 )   Hyriopsis cumingii can be used for pearl cultivation, its soft body is edible and its shell can also be made into pearl nuclei. It is the most important pearl cultivating shellfish for freshwater pearls in China. To investigate the effects of morphological traits on weight traits of juvenile populations with two different shell colors in the white breeding lines of H.cumingii and to optimize the breeding strategies for mussels, and its application in different breeding scenarios, a total of 171 individuals each from the green-shelled white and yellow-shelled white lines were randomly selected. Four morphological traits (shell length, total height, shell height, and shell width) as well as three weight traits (live weight, shell weight, and soft body weight) were measured, and subsequently processed by covariance analysis, correlation analysis, path analysis, and stepwise multiple regression analysis. The results showed that there were certain differences in the morphological traits of juvenile populations with two different shell colors, and the traits were extremely significantly correlated (P<0.01), and the coefficient of variation of their weight traits was higher than that of morphological traits. The path analysis using weight traits as the dependent variable revealed that for the green-shelled white line, shell width has the greatest direct effect on both live weight and shell weight, while shell length has the greatest direct effect on soft body weight. For the yellow-shelled white line, total height has the greatest direct effect on all weight traits. The results of determination coefficient of the morphological traits on weight traits of juvenile populations with two different shell colors were consistent with the results of path analysis. The estimated values of the optimal regression equations of juvenile populations with two different shell colors constructed by stepwise multiple regression were not significantly different from the actual values, indicating that the optimal regression equations can be applied in practical breeding work. In conclusion, there are differences in the morphological traits of juvenile populations with two different shell colors of H. cumingii, and the core morphological traits affecting the live weight, shell weight and soft body weight are different. During the breeding process of H. cumingii, it is necessary to distinguish the shell color phenotypes and combine specific breeding scenarios to make the breeding work scienjpgic and reasonable.

The results showed that the crude protein content, essential amino acid content, delicious amino acid content and mineral (Na, K, Mg, Ca, Mn, Se) content of the Taihu Lake 2 were significantly higher than those of native species (P<0.01), while the crude fat content and several unsaturated fatty acid (C18∶1, C20∶1, C20∶4 n-6 and monounsaturated fatty acid) content were significantly lower than those of native species. In addition, the proportion of delicious amino acids of Taihu Lake 2 was significantly higher than that of native species. It is confirmed that genetic factors are the main factor affecting the muscle nutritional value of introduced species of Macrobrachium nipponense, while the rice-shrimp co-cultivation environment has no significant effect on the nutritional components of introduced species. Taihu Lake 2 has better performance in protein quality, delicious degree and mineral nutrition, has higher food value and health benefits, and can provide scienjpgic basis for the promotion of improved varieties of Macrobrachium nipponense and the development of integrated rice-shrimp co-cultivation model.

Effect of integrated rice-fish farming system on soil microbial diversity and function REN Jindong, SUN Yuan, CUI Yanyan, WEI Xiaoming, TANG Yong 2025, 66 (8):  1829-1834.  DOI: 10.16178/j.issn.0528-9017.20240517 Abstract ( 19 )   HTML ( 9 )   PDF (3860KB) ( 69 )   To investigate the impact of integrated rice-fish system on soil microbial diversity, this study conducted a comparative analysis of soil microorganisms under integrated rice-fish and rice monoculture systems using 16S sequencing technology. The results revealed significant differences in the relative abundances of Chloroflexi and Acidobacteriota in soil samples during the first and second months. At the genus level, the relative abundance of Acidobacteriales was significantly lower during the first and second months under the integrated rice-fish system than under the rice monoculture system. Notably, the abundance of Bacillus under the integrated rice-fish system system significantly decreased by the fourth month compared with rice monoculture, whereas Clostridium sensu stricto increased throughout all periods. Diversity and functional enrichment analyses demonstrated that the chao diversity index of soil microorganisms under the integrated rice-fish system increased dramatically from the first to the fourth month, surpassing the improvement observed in the rice monoculture system. Furthermore, significant functional differences were idenjpgied in metabolic pathways such as chemoheterotrophy, aerobic chemoheterotrophy, fermentation, nitrogen fixation, methylotrophy, hydrocarbon degradation, methanotrophy, and animal parasites or symbionts. Specifically, the integrated rice-fish system exhibited enhanced enrichment of nitrogen-fixation and fermentation functional microorganisms. These findings indicate that integrated rice-fish system significantly enhances soil microbial diversity, fertility, and improves soil ecological benefit benefits.

In recent years, the vigorous development of plastic industry produced serious environmental pollution. Microplastics can enrich in aquatic products through the food chain and harm human health. This review summarized the widely used methods for digesting aquatic product tissues and their removal effects on biological tissues, introduced the conventional methods for separating and staining the solution density of digested aquatic product tissues and briefly introduced the advantages and disadvantages of using electron microscopy, Fourier infrared spectrometer, Raman spectrometer, the Py-GC/MS for idenjpgying microplastic. Finally, the rapid analysis methods proposed in recent two years were collected. Spectroscopy as a classical detection method, often used to idenjpgy microplastic larger than 50 μm in size, as a supplementary method to the thermal cracking of temperament method can accurately idenjpgy 50 μm to nanoscale plastic particles, within the scope of implementation in μg reliable quantitative. However, the sample preparation and analysis time of instrumental analysis methods is relatively long, and their applicable scopes are different. Therefore, future study and development should be more in the direction of high throughput, more flexible and easier to operate. Figures and Tables | References | Related Articles | Metrics

The "Tonglu Model" of integrated rice-turtle farming—key technologies and promotion demonstration of ex-situ symbiosis LI Hong, GUO Kefan, HUANG Fuyong, TANG Jinyu, LIANG Xiao, ZHOU Yanping 2025, 66 (8):  1858-1861.  DOI: 10.16178/j.issn.0528-9017.20250364 Abstract ( 21 )   HTML ( 3 )   PDF (1121KB) ( 74 )   The ex-situ symbiosis of rice and turtle is a new integrated rice-turtle farming model, which has advantages such as “small area proportion, easy farming and management, high survival and recovery rate, and good comprehensive benefits”. It is called the “Tonglu Model” because it was first promoted on a large scale in Tonglu County, Zhejiang Province, and achieved remarkable results. This paper systematically expounds the core points of this technology, including key technologies such as the optimization of environmental conditions, the construction of field engineering, the refined management of rice planting, the standardized breeding of Chinese soft-shelled turtles and the recycling treatment of tail water. Results showed that scienjpgic environmental selection and field engineering design are the foundation of technology implementation. The collaborative management of rice and turtles (such as fertilizing fields with Chinese soft-shelled turtle manure) can significantly reduce the use of chemical fertilizers, lower agricultural non-point source pollution, enhance soil fertility and biodiversity, and form an ecological cycle system of “mutual benefit between planting and breeding”. Empirical analysis showed that this model can increase land utilization rate by 15% to 20%, raise the added value of rice and turtle products by more than 50%, and achieve a comprehensive income of over 10 000 yuan per 667 m2. At present, Tonglu County has promoted and demonstrated an area of 848.33 hm2, achieving synergy among the economy, ecology and society, and providing a replicable practical model for the green transformation of agriculture. The results can provide important references for the standardized promotion of the rice-turtle ex-situ symbiosis technology and the sustainable development of agriculture.

Effects of microplastics on the growth and cadmium accumulation of Brassica chinensis L. PAN Qianxuan, GUO Liang, GUO Jingjie, ZOU Lei, ZHENG Yining 2025, 66 (8):  1882-1890.  DOI: 10.16178/j.issn.0528-9017.20250235 Abstract ( 20 )   HTML ( 6 )   PDF (4108KB) ( 77 )   The combined pollution of microplastics (MPs) and cadmium (Cd) in soils is becoming increasingly prevalent, posing potential threats to agricultural product safety. However, the interaction mechanisms and ecological risks between these pollutants remain unclear. In this study, a pot experiment was conducted with different concentrations of polypropylene (PP) MPs (0.25% and 1.00%) and Cd (0.649 mg·kg-1) in single and combined treatments to investigate their effects on growth parameters, photosynthetic characteristics, and Cd accumulation in Brassica chinensis L.. The results demonstrated that PP alone exhibited concentration-dependent inhibitory effects on plant growth and photosynthesis, while Cd alone promoted plant growth. The combined exposure showed synergistic inhibitory effects and significantly enhanced Cd accumulation in both the aboveground and underground parts of Brassica chinensis L., with the effects intensifying at higher PP concentrations. This study revealed the toxic effects of individual and combined MPs-Cd pollution on Brassica chinensis L., providing important scienjpgic evidence for ensuring agricultural product safety and managing soil combined pollution.

Effects of combined application of bio-organic fertilizer and microbial agents on soil properties and tomato quality in greenhouse continuous cropping obstacle HE Qinling, CAI Peiwen, YUE Cong, FENG Xiaolu, MA Haoyu, WANG Zhe, WU Xiangyu, ZHOU Xiaoyu, JIN Yue, ZHANG Xiancui, LI Peng, ZHAO Mingxing, WU Choufei 2025, 66 (8):  1905-1909.  DOI: 10.16178/j.issn.0528-9017.20250251 Abstract ( 21 )   HTML ( 6 )   PDF (2488KB) ( 78 )   Tomato (Solanum lycopersicum), as an important economic crop, is widely and intensively cultivated. However, large-scale cultivation has led to soil continuous cropping obstacles, which directly threaten the sustainable and stable development of the greenhouse industry. Studies have shown that microbial agents can significantly improve soil quality and mitigate the toxicity of heavy metals and pesticides. This study conducted a five-year experiment on tomato fields under long-term continuous cropping, applying conventional fertilization and microbial fertilizer treatments. The evaluation indicators included soil nutrient content, enzyme activity, allelopathic substances content, and tomato yield. The results indicated that long-term continuous cropping led to a decrease in soil nutrient content, an increase in allelopathic substance content, and a reduction in tomato yield. However, microbial fertilizers and microbial agents were found to alleviate the soil continuous cropping obstacles and improve soil health. Additionally, we observed significant correlations between tomato yield and soil organic matter, total nitrogen content, available potassium, and POX enzyme activity, with correlation coefficients of 0.720, 0.645, 0.701, and 0.596, respectively. In conclusion, microbial agents can effectively regulate soil health and mitigate tomato continuous cropping obstacles. The findings of this study provide scienjpgic evidence for soil health management and the prevention of tomato continuous cropping obstacles.

Biological agents developed by biotechnology, with high efficiency, low toxicity and specific typical characteristics, are widely used in the preparation of modern pesticides, fertilizers and bio-products active substances. Scienjpgic assessment of the safety and ecological application potential of biological agents is conducive to the optimization of the green production of intensive tea gardens and the promotion of high-quality development of the tea industry. Through reviewing relevant research literature at home and abroad, we analyzed the development history, functional role, main types and residue risk of chemical pesticides from the perspective of chemical replacement and environmental ecological protection in tea gardens, and explored the efficacy, application and potential of biological agents in green prevention and control of tea gardens, so as to provide support for the ecological application of biological agents in the green prevention and control of tea gardens. It was found that the overuse of chemical agents increased resistance of plant pathogens, jeopardized human and animal health, and caused serious impacts on the ecological environment, while biological agents originated from living organisms or their metabolites, and were ideally suited to inhibit fungi, bacteria, viruses, and nematode control in tea gardens. From the perspectives of product monitoring and biodiversity assessment, integrated prevention and control system and resistance management, and ecological risk assessment, it was proposed to establish safety control measures for biological agents. And from the perspectives of product quality enhancement, application timing and conditions, and application technology, it was proposed to improve the application efficiency of biological agents. Finally, from the perspectives of publicity and education, business model innovation, policy support and supervision, as was as research and development of related functional biomaterials and green inputs, it was proposed to strengthen the application and promotion of biological agents. Therefore, the application of biological agents instead of chemical agents is conducive to solving environmental risks and realizing green prevention and control.

Study on the control of toxin contamination from Fusarium head blight SHOU Linfei, LI Chunyuan, ZHU Jianzhen, QIU Haiping, CHAI Rongyao, ZHANG Zhen 2025, 66 (8):  1938-1943.  DOI: 10.16178/j.issn.0528-9017.20240099 Abstract ( 16 )   HTML ( 3 )   PDF (1185KB) ( 81 )   Fusarium head blight (FHB) not only directly reduces wheat yield but also contaminates wheat grains with toxin produced by its pathogens, posing significant food safety risks. Therefore, improving FHB management and advancing toxin mitigation technologies are critical. This study evaluated the efficacy of mainstream FHB control agents in both disease suppression and toxin reduction. Two-year trials demonstrated that spraying 40% prothioconazole·tebuconazole suspension concentrate (600 mL·hm-2) or a combination of 200 g·L-1 pydiflumetofen suspension concentrate (900 mL·hm-2) and 250 g·L-1 propiconazole emulsifiable concentrate (600 mL·hm-2) at the early flowering stage achieved over 77.0% control efficacy against FHB. These treatments restricted deoxynivalenol (DON) and zearalenone (ZEN) levels below 700 μg·kg-1 and 200 μg·kg-1, respectively. A second application 7 days after the initial treatment did not significantly enhance control efficacy but further reduced toxin levels in epidemic years. Additionally, pre-harvest spraying of 25% phenamacril suspension concentrate (1 500 mL·hm-2) further decreased Fusarium toxin content in grains, though effectiveness varied between years, with more pronounced reductions during FHB epidemics. These findings provide practical insights for managing Fusarium toxins in wheat. Figures and Tables | References | Related Articles | Metrics

The results showed that treatments 2 and 3 exhibited superior control efficacy against Fusarium head blight and powdery mildew in wheat compared with untreated plots and conventional chemical treatments. Notably, their control efficacy against powdery mildew was particularly significant, with treatment 2 and 3 achieving 99.79% and 99.80%, respectively. Both treatments also demonstrated 85.71% efficacy against Fusarium head blight. Treatment 2 showed moderate efficacy (66.67%) against sharp eyespot, while treatment 3 achieved complete control (100.00%). Therefore, treatment 3 is recommended for fields with severe sharp eyespot outbreaks. All treatments increased wheat yield by 7.36%-11.98%, with economic benefits rising by 124.88-203.29 yuan per 667 m2 compared to the control, likely due to the yield-enhancing effects of the plant growth regulators in treatments 2 and 3. The two combination treatments effectively controlled multiple wheat diseases, promoted pesticide reduction and efficiency, and improved yield, demonstrating potential for broader application.

Analysis of the current status and variation trend of the cultivated land quality in Zhejiang Province under long-term location monitoring LIAN Zhenghua, CHEN Yiding, KONG Haimin, CHEN Hongjin 2025, 66 (8):  2002-2007.  DOI: 10.16178/j.issn.0528-9017.20240618 Abstract ( 34 )   HTML ( 10 )   PDF (1671KB) ( 79 )   Based on the monitored data of cultivated land quality from the monitoring sites during the period of 2009-2022, this study performed analysis of the current status of the soil quality of cultivated land in Zhejiang Province, and evaluated the variation trend of the contents of soil nutrients in the cultivated land. The results showed that the average contents of soil organic matter and total nitrogen in the topsoil at the monitoring sites were at a high level, with high levels of available phosphorus and medium levels of available potassium. Among them, for the paddy field monitoring sites, the average contents of soil organic matter, total nitrogen, and available phosphorus were at a relatively high level, while the available potassium was at a medium to lower level. For the dryland monitoring sites, the average contents of soil organic matter and total nitrogen were at a relatively high level, while the average contents of available phosphorus and available potassium is at a high level. In addition, the results of 14 years of consecutive monitoring showed that as a whole, soil fertility of paddy field performed a stable and upward trend, however, deficiencies of phosphorus and potassium commonly occurred. Besides, we found an improvement in soil fertility of dryland field, especially an obvious increase in soil organic matter and enrichment of soil phosphorus and potassium content. Howerer, the acidification degree of drylands was higher than that of paddy fields, and it had a tendency to intensify. Therefore, it is necessary to carry out works (e.g., soil testing and formula fertilization, and fertilizer quota system) to achieve a balance of soil nutrients. At the same time, soil acidification management is needed to suppress the acidification process of cultivated land. Figures and Tables | References | Related Articles | Metrics

Study on the effects of different thermophilic microorganisms on high-temperature composting of pig manure WANG Yafei, WANG Jingbang, GUO Rui, ZHU Fengxiang, ZHANG Tao, HONG Chunlai, YAO Yanlai 2025, 66 (8):  2015-2024.  DOI: 10.16178/j.issn.0528-9017.20250305 Abstract ( 14 )   HTML ( 3 )   PDF (6881KB) ( 75 )   High-temperature composting of biomass waste materials such as livestock and poultry manure to prepare organic fertilizer is the main utilization method of livestock and poultry manure. Thermophilic microorganisms can significantly enhance composting efficiency. However, current research remains limited regarding the effects of different thermophilic microbial strains and their combinations on livestock manure composting. This study systematically investigated the impacts of single or compound inoculations of thermophilic bacteria on pig manure composting. Three thermophilic strains (Ureibacillus thermosphaericus Z2-1, Ureibacillus sp. Z4-4, and Geobacillus proteiniphilus H3-1) were employed to establish seven treatment groups and one control group (CK) for high-temperature composting experiments. The results demonstrated that all microbial inoculations elevated composting temperature, reduced nitrogen loss, and improved seed germination rate of final products. Notably, treatment G inoculated with the three-strain consortium achieved the highest temperature (77.2 ℃) and longest duration above 70.0 ℃ (5 days), enhancing harmless efficiency. Besides, microbial activities promoted organic matter degradation, the organic matter content of treatment G decreased the most, and the total nitrogen content decreased the least, indicating a better nitrogen retention effect. The germination index (GI) values of all treatments exceeded 80.0% at the end of composting, with treatment G reaching 100.1%, higher than CK (85.6%). Additionally, the compound inoculated with the bacterial agent compounded from three thermophilic bacteria increased the relative abundance of Bacillota in the compost community, accelerating organic matter decomposition. These findings indicate that compound thermophilic inoculants effectively promote organic matter transformation, enhance compost quality, and improve maturation efficiency in pig manure composting systems.

Meanwhile, phosphorus mining resources are limited and can't be reproduced. There could be a seriously potential phosphorus crisis in the future with the increasing of the population and the demand for food. Therefore, activating the insoluble phosphorus in soil, improving the phosphorus bioavailability of soil and efficiently utilizing potential phosphorus resources in soil are of great significance to the sustainable development of agriculture. In this review, the changes of phosphorus components, phoD and pqqc gene abundance and phosphatase in soil with different fertilization patterns in farmland in the past five years were summarized. In order to provide a theoretical basis for analyzing the relevant mechanism of phosphorus conversion, reducing phosphorus loss and improving phosphate fertilizer utilization, the key influencing factors of soil phosphorus conversion were sorted out, the microbial mechanism of phosphorus conversion by different fertilization patterns and the regulatory factors of microbial phosphorus activation process were compared, and the influence of different phosphorus sources on the soil environment was analyzed.

Structural and adsorption properties of different biochar derived from agricultural and forestry wastes YING Hong, LUO Yan, JIN Shuquan, ZHOU Jinbo, WANG Minghu 2025, 66 (8):  2039-2046.  DOI: 10.16178/j.issn.0528-9017.20240971 Abstract ( 20 )   HTML ( 6 )   PDF (11344KB) ( 73 )   In order to explore the properties of four kinds of biochar materials (RSBC, MSBC, WSBC and SDBC), derived from rice straw, maize straw, walnut shell and branch sawdust, respectively, their chemical composition, morphology, aperture structure and functional groups were analyzed. The adsorption capacity of different biochar was also investigated with heavy metal Cu2+ as the study object. The results showed that the carbon content of different biochar was within the range of 42.04%-81.07%, all of which contained abundant oxygen-containing functional groups and chemically stable C-H and aromatic rings. The morphology of biochar was different, and the specific surface area was SDBC>WSBC>MSBC>RSBC. Four kinds of biochar exhibited different adsorption capacities for Cu2+, and the adsorption rates of WSBC and SDBC were related to the concentration of Cu2+, while the adsorption processes of Cu2+ on RSBC and MSBC were mainly controlled by chemical action, and the adsorption capacity was ranked as RSBC>MSBC>WSBC>SDBC. The adsorption mechanisms of Cu2+ on different biochar were related to their surface negative charges, oxygen-containing functional groups, specific surface area and inorganic mineral components, among which the abundant oxygen-containing functional groups on RSBC surface was the important key for its best adsorption performance.

While promoting agricultural development and increasing farmers' income, we must also protect the environment and ensure the green and pollution-free nature of agricultural products. This article systematically summarizes the main practices, achievements, and innovative measures of agricultural green development in Zhejiang Province in recent years, analyzes the problems existing in agricultural green development work, and proposes countermeasures and suggestions for continuously promoting agricultural green development. The green development of agriculture in the new era requires the government to promote policies and assessments in an integrated manner, clarify work carriers, and innovate the integrated system. Specifically, it should be implemented in the prevention and control of agricultural non-point source pollution, coordinated efficiency reduction and carbon reduction in agricultural production, ecological restoration and protection of agriculture, and transformation of agricultural green development. Vigorously promoting green development in agriculture is a key measure to implement the concept of green development in the new era, an important gripper to promote the structural reform of the agricultural supply side, and an inevitable choice for sustainable and high-quality development of agriculture. It is of great significance for promoting the strategy of rural revitalization, improving the growth mode of agricultural economy, and enhancing the competitiveness of China's agricultural product market.
