摘要
为解析不同拌种处理对大豆苗期质量、生育中后期农艺性状及最终产量构成的调控效应,为构建环境友好型大豆高产栽培技术体系提供理论支撑,本研究以9个主栽大豆品种(东农豆253、东生37和北豆40等)为材料,分别使用了3种微生物种衣剂组合对种子进行处理,T1(哈茨木霉+娄彻氏链霉菌复合菌剂绿施达,配壳聚糖粘合剂亮御,1亿活菌·g^(-1)),T2(枯草芽孢杆菌+地衣芽孢杆菌复合菌剂,配壳聚糖钙镁硼钼微肥粘合剂妙无限,1亿活菌·g^(-1)),T3[解淀粉芽孢杆菌+枯草芽孢杆菌复合菌剂,配壳聚糖粘合剂(亮御),1亿活菌·g^(-1)],同时设置两个对照处理,分别为化学种衣剂对照(CK1)和空白对照(CK2)。系统比较了不同微生物种衣剂处理后大豆根冠比、叶面积指数、叶绿素含量、净光合速率和产量的变化情况。结果表明:T2处理的大豆根冠比、叶面积指数、叶绿素含量、净光合速率和产量均显著优于其他处理。由于不同品种之间和不同微生物菌株功能之间存在特异性,沃豆19表现出对化学种衣剂CK1的特异性响应,T3处理下垦豆310也表现出特异性响应,其根冠比显著高于其他处理。T3在鼓粒期表现出较弱的持效性,处理后的垦农18和合农85叶面积指数接近CK1。特别是T2的东农豆253的根冠比、叶面积指数、叶绿素含量、净光合速率和产量整体上均高于其他品种×处理组合。综上,微生物种衣剂与东农豆253的组合为最优方案,建议在当地优先推广。
To analyze the regulatory effects of different seed treatments on soybean seedling quality,mid-late growth stage agronomic traits,and final yield components,and to provide theoretical support for constructing an environmentally friendly high-yield soybean cultivation system,this study was conducted as follows.Nine major soybean varieties(Dongnongdou 253,Dongsheng 37 and Beidou 40,et al.)were used as materials,and three combination of microbial seed coating agents Heilongjiang Jiaxiang Agriculture,Bayer,and Moon Bioscience were applied for seed dressing,T1(Trichoderma harzianum+Streptomyces rochei compound microbial agent Lüshida,combined with chitosan binder Liangyu,1×10^(8) CFU·g^(-1)),T2(Bacillus subtilis+Bacillus licheniformis compound microbial agent,combined with chitosan-based calcium-magnesium-boron-molybdenum micronutrient fertilizer binder Miaowuxian,1×10^(8) CFU·g^(-1)),T3[Bacillus amyloliquefaciens+Bacillus subtilis compound microbial agent,combined with chitosan binder(Liangyu),1×10^(8) CFU·g^(-1)],and two control treatments,chemical seed coating control(CK1)and blank control(CK2)were set up.The effects of different microbial seed coating agent treatments on the root shoot ratio,leaf area index,chlorophyll content,net photosynthetic rate and yield of soybeans were comparatively analyzed.Results are as follows:the root shoot ratio,leaf area index,chlorophyll content,net photosynthetic rate and yield of soybean processed by treatment T2 have significant advantages over other treatments.Due to the specificity among different varieties and the functions of different microbial strains,Wodou 19 treated with the chemical seed coating agent CK1 showed a specific response to the chemical seed coating agent.While Kendou 310 treated with treatment 3 also showed a specific response to treatment T3,its root shoot ratio is significantly higher than that of other treatments.The treatment 3 showed a relatively weak persistence in the R6 stage.The R6 leaf area index of Kenong 18 and Henong 85 after treatment T3 was close to CK1.In particular,the root-shoot ratio,leaf area index,chlorophyll content,net photosynthetic rate and yield of Dongnongdou 253 treat ed with treatment T2 were generally higher than those of other variety×treatment combinations.In conclusion,microbial seed coating agent×Dongnongdou 253 combinations are the optimal solutions,and it is recommended to give priority to promotion in local areas.
