 摘要： In the context of "high-quality development" construction,the establishment and operational status of the national-level scientific research platforms at provincial universities—specifically,the large-scale instrument sharing platforms—are critically linked to the production of scientific research outcomes and the development of interdisciplinary talents.This study focuses on the public platform of the State Key Laboratory of Tea Plant Germplasm Innovation and Resource Utilization,aiming to innovate the management system,establish a technical platform,effectively integrate resources,and actively engage graduate students in the platform management.While ensuring the efficient operation of the large-scale instrument platform at state key laboratories,it offers a novel approach to cultivating graduate students into versatile talents.

 摘要： Based on questionnaire surveys and field interviews conducted with various types of agricultural production organizations across five districts and four counties in Daqing City,this study combines relevant theoretical frameworks to systematically examine the evolution,performance,and influencing factors of governance mechanisms within these organizations.Using both quantitative and inductive analytical methods,the paper proposes innovative designs and supporting measures for improving governance mechanisms.The findings reveal that,amid large-scale farmland circulation,the governance mechanisms of agricultural production organizations in Daqing City are evolving from traditional to modern structures.However,challenges remain in areas such as decision-making efficiency,benefit distribution,and supervision mechanisms.In response,this study proposes innovative governance designs focusing on decision-making processes,profit-sharing mechanisms,and risk prevention.Corresponding policy recommendations are also provided to support the sustainable development of agricultural modernization in China.

 摘要： Under the background of "Digital Commerce for Rural Vitalization",rural E-commerce has experienced rapid development.However,agricultural products like strawberries,often produced by small-scale,fragmented,and less competitive individual farmers,struggle to meet the compliance and scalability demands of E-commerce,thereby constraining high-quality local economic development.Aiming to address this issue,this paper,guided by relevant policies and strategies,employs case analysis and logical deduction to explore the industrialization path of the "Cooperative+E-commerce" model for the strawberry industry.The research finds that by optimizing the cooperative’s organizational structure,implementing multi-channel E-commerce strategies,upgrading the supply chain (including cold chain and quality traceability),and engaging in collaborative brand building,a robust industrial system can be formed.Supplemented by benefit evaluation,policy support,and regulatory oversight,this system can effectively bridge small-scale production with the broader market.This study concludes that this pathway can enhance the added value of the strawberry industry,increase farmer incomes,and provide practical insights for promoting high-quality local economic development.

 摘要： The water conservancy construction and soil and water conservation projects in New China have reshaped the tea industry landscape in Xinyang City of Henan Province from multiple dimensions.In terms of hydraulic technology,engineering systems represented by the Nanwan Irrigation District redefined the watershed irrigation pattern,while the application of modern agricultural technologies such as sprinkler and electric irrigation accelerated the shift from traditional experience to scientific management in tea garden practices.Ecologically,systematic soil and water management significantly improved growing conditions,making it possible for tea cultivation to break through the traditional geographical limitation of "tea does not grow north of the Huai River." This integrated governance model not only laid the foundation for the northward expansion of Xinyang’s tea industry across the Huai River but also facilitated the transition toward scale and intensification through improved irrigation infrastructure and the breeding of cold-resistant tea varieties.Ultimately,driven by the tripartite interactive mechanism of "engineering governance-ecological improvement-spatial expansion," the tea industry in Xinyang achieved a historic leap from traditional production to modern intensive development.

 摘要：  [Objectives]To explore the effect of selenium (Se) on inhibiting embryo abortion and enhancing seedling cultivation quality of Red sandalwood (Pterocarpus santalinus).[Methods]Based on prior cultivation practices and experimental research,three categories comprising 13 forest soil nutrient management schemes were designed to investigate the synergistic effects of Se,NPK compound fertilizers,and enzyme-microbe fermented organic fertilizers (EFOF) on embryo abortion,winged pod development,and seedling quality of Red sandalwood.[Results]Increasing the Se content in the soil,particularly in the form of selenite/Se(IV),within one month following the harvest of Red sandalwood pods and within two months prior to flower withering,significantly reduced embryo abortion percentage (EAP),and consequently improved seed quality and yield per plant.The effect of Se application was markedly greater than that of the single application of nitrogen (N),phosphorus (P),potassium (K),boron (B) fertilizers,or organic fertilizers.Furthermore,when Se was applied in combination with NPK compound fertilizers and EFOF,these beneficial effects were significantly enhanced.When Se(IV) was applied individually,the EAP decreased by 62.4%,reaching 24.8% at 8 weeks after flower withering (compared to 65.9% in the unmanaged control,UMC).Following winged pod maturation,the percentage of empty winged pods (PEWP) declined by 65.2% to 16.8% (UMC:48.2%),the average individual winged pod weight (IWPW) increased by 69.1% to 0.690 g per fruit (UMC:0.408 g),and the winged pod yield (WPY) rose by 214.8% to 4.03 kg (UMC:1.28 kg).Additionally,the blasted seed percentage (BSP) was reduced by 51.2% to 29.9% (UMC:61.3%),and the 100-seed weight (HSW) increased by 96.0% to 8.37 g (UMC:4.27 g).Following sowing in the nursery,the seedling emergence rate (SER) increased by 6.57-fold,reaching 59.8% (UMC:7.9%).Additionally,the whole plant biomass of 6-month-old seedlings increased by 52.9%,attaining 1.56 g (UMC:1.02 g).The combined application of EFOF+NPK+Se(IV) significantly reduced the EAP,PEWP,and BSP by 56.5%,46.0%,and 56.3%,respectively,compared to the single application of Se(IV).Furthermore,these percentages decreased by 79.7%,78.9%,and 71.8%,respectively,relative to the single application of NPK compound fertilizers,and by 79.0%,74.5%,and 72.1%,respectively,compared to the single application of EFOF.Additionally,the SER increased by 34.6%,141.0%,and 287.0%,respectively,when compared to the single application of Se(IV),NPK compound fertilizers,and EFOF.[Conclusions]Enhancing the nutrient status of forest soils,particularly the concentration of Se(IV),constitutes a critical technical approach to improving the resistance of Red sandalwood to low-temperature stress during its flowering and fruiting stages,thereby preventing embryo abortion.

 摘要： [Objectives]To establish an HPLC method for the quantitative determination of multiple phenolic acid components in Tetracera asiatica medicinal material,providing a basis for establishing its quality standards.[Methods]An Inertsil ODS-C₁₈ column (250 mm×4.6 mm,5 μm) was used.The mobile phase consisted of acetonitrile-0.2% phosphoric acid solution (10：90).The flow rate was 1.0 mL/min.The detection wavelength was 274 nm.The column temperature was 25 ℃.The injection volume was 10 μL.The content of three components,gallic acid,protocatechuic acid,and protocatechualdehyde,was determined in 13 batches of T. asiatica.[Results]Gallic acid showed good linearity within the range of 0.020-6.400 μg/mL,protocatechuic acid within 0.201-6.432 μg/mL,and protocatechualdehyde within 0.202-6.464 μg/mL (r>0.999 0).The average recovery rates ranged from 98.61% to 101.17%,with RSDs between 1.21% and 2.69%.[Conclusions]The quantitative determination method established in this study is simple and feasible,and can provide a basis for the quality evaluation of T. asiatica.

 摘要： [Objectives]To explore the effects of high soil temperature stress on microorganisms utilizing different carbon sources in the rhizosphere of pepper seedlings.[Methods]Using seedlings of the main pepper cultivar ‘Reyin 1’ as experimental materials,five soil temperature gradients (25,30,35,40,and 45 ℃) were established.After a 96 d cultivation,soil nutrient content and soil microbial functional diversity were measured to elucidate the impact of high soil temperature on the soil microenvironment.[Results]As soil temperature increased,the contents of total nitrogen,alkaline hydrolyzable nitrogen,available phosphorus,and rapidly available potassium generally showed a decreasing trend.However,under the 45 ℃ treatment,the contents of total nitrogen,available phosphorus,and rapidly available potassium were the highest among all treatments,although the alkaline hydrolyzable nitrogen content was significantly lower compared to the other treatments.BIOLOG analysis revealed that with increasing soil temperature,the average soil microbial absorbance value and the Shannon diversity index decreased significantly.In contrast,the Shannon evenness index and the Simpson dominance index showed no significant differences across the different temperature treatments.This indicates that as soil temperature rises,the carbon source utilization capacity of the soil microbial community decreases,leading to reduced overall carbon metabolic activity and microbial functional diversity,while the dominant microbial populations remained unchanged during this process.Principal component analysis further confirmed effective separation among the different temperature treatments,suggesting that high soil stress significantly altered the structure of the soil microbial community.[Conclusions]In practical production,appropriate measures should be taken to decrease soil temperature to create a favorable rhizosphere microenvironment and thereby promote crop growth.

 摘要： [Objectives]Based on spectrophotometry,a method for determining the total flavonoid content in milk powder was established by optimizing sample pretreatment conditions,and method validation was performed.[Methods]Total flavonoids in milk powder were extracted with ethanol using 45 ℃ water bath ultrasonication for 60 min.Flavonoids contain a benzopyran ring structure and react with aluminum nitrate in a potassium acetate environment to form a yellow complex.The absorbance of this complex was measured at 420 nm for quantitative determination.[Results]The method exhibited a good linear relationship within the range of 0.2-1.0 mg.The limit of detection (LOD) was 0.05 g/100 g,and the limit of quantification (LOQ) was 0.3 g/100 g.When the spiked amount of total flavonoids was in the range of 0.3% to 1.0%,the spike recovery rates were 99.3% to 103.4%,and the relative standard deviations (RSDs) were less than 3.0%.[Conclusions]This method offers advantages such as rapidness,accuracy,good stability,and high sensitivity,and can be used for the detection of total flavonoid content in milk powder.
