摘要: 【目的】探究小麦种子复合微生物种衣剂的制备及其应用效果,为开发高活性复合微生物种衣剂提供参考。【方法】以小麦种子为试验材料,设置复合微生物种衣剂1(贝莱斯芽孢杆菌SSF6+枯草芽孢杆菌LU5)和复合微生物种衣剂2(贝莱斯芽孢杆菌SSF6+枯草芽孢杆菌LU5+长枝木霉)两个处理,以清水为对照(CK),进行种衣剂、包衣种子制备,测定不同复合微生物种衣剂理化性质及其对小麦发芽率和幼苗生长的影响,并筛选复合微生物种衣剂的最佳组成及比例。【结果】两个复合微生物种衣剂的最佳性质为:pH值7.38~7.39、包衣均匀度≥90%、脱落率<8%,低温(4 ℃)和热贮(54 ℃)稳定性良好,均符合相关标准。两个复合微生物种衣剂的小麦种子发芽率均显著高于CK(P<0.05);复合微生物种衣剂1在药种比为1∶75时发芽率最高,复合微生物种衣剂2在药种比为1∶50时发芽率最高,与CK相比分别提高52.98%和56.39%。盆栽试验表明,两个复合微生物种衣剂均可促进小麦幼苗生长;与CK相比,复合微生物种衣剂1的地上部幼苗高度、地下部根长分别提高17.54%和16.90%,小麦地下部干重、地上部干重和根冠比分别提高25.00%、21.05%、6.68%;复合微生物种衣剂2的地上部幼苗高度、地下部根长分别提高25.73%和25.35%,小麦地下部干重、地上部干重和根冠比分别提高62.50%、47.37%、21.69%。【结论】贝莱斯芽孢杆菌SSF6+枯草芽孢杆菌LU5+长枝木霉在药种比为1∶50时具有稳定性和促生长能力,能够提高小麦的发芽率,可作为小麦种子较优的种衣剂。

Abstract: 【Objective】To investigate the preparation and application effects of compound microbial seed coating agents for wheat seeds,providing a reference for the development of highly active compound microbial seed coating agents.【Methods】Wheat seeds were used as experimental materials. Two treatments were set up:compound microbial seed coating agent 1(Bacillus velezensis SSF6+B. subtilis LU5)and compound microbial seed coating agent 2(B. velezensis SSF6+B. subtilis LU5+Trichoderma longibrachiatum),and distilled water was used as the control(CK). Seed coating agents and coated seeds were prepared. The physicochemical properties of different compound microbial seed coating agents and their effects on wheat germination rate and seedling growth were determined,and the optimal composition and ratio of the compound microbial seed coating agents were screened.【Results】The optimal properties of two compound microbial seed coating agents were:pH 7.38-7.39,coating uniformity≥90%,shedding rate<8%,and good stability at low temperature(4 ℃)and heat storage(54 ℃),all in compliance with relevant standards. The germination rates of wheat seeds treated with both compound microbial seed coating agents were significantly higher than that of CK(P<0.05). Compound microbial seed coating agent 1 had the highest germination rate at an agent-to-seed ratio of 1∶75,and compound microbial seed coating agent 2 had the highest germination rate at an agent-to-seed ratio of 1∶50,with an increase of 52.98% and 56.39%,respectively,compared with CK. Pot experiments showed that both compound microbial seed coating agents promoted wheat seedling growth. Compared with CK,aboveground seedling height and belowground root length of compound microbial seed coating agent 1 increased by 17.54% and 16.90%,respectively;belowground dry weight,aboveground dry weight,and root-to-shoot ratio increased by 25.00%,21.05%,and 6.68%,respectively;aboveground seedling height and belowground root length of compound microbial seed coating agent 2 increased by 25.73% and 25.35%,respectively;belowground dry weight,aboveground dry weight,and root-to-shoot ratio increased by 62.50%,47.37%,and 21.69%,respectively.【Conclusion】B. velezensis SSF6+B. subtilis LU5+T. longibrachiatum at an agent-to-seed ratio of 1∶50 shows stability and growth-promoting ability,can improve wheat germination rate,and may serve as a superior seed coating agent for wheat seeds.
