【摘要】 选择稻-麦轮作模式秸秆还田短期定位试验田块，于2016—2019年连续施用由棘孢木霉、黑曲霉、黑根霉、青霉4种不同微生物菌分别与枯草芽孢杆菌组合制成的秸秆腐熟剂，于2018和2019年分别调查不同秸秆腐熟剂处理的小麦赤霉病病情。结果表明，小麦抽穗扬花期的降雨量是赤霉病发生程度的决定性因素；与秸秆不还田相比，短期秸秆还田对赤霉病的发生并未表现出明显加重趋势；在赤霉病重发生年份，棘孢木霉和解淀粉芽孢杆菌组合可明显减轻赤霉病的发生。更多还原

【Abstract】 A short-term positioning test field of straw returning in rice wheat rotation mode was selected and the straw was treated with straw ripening agent made of four different microbial bacteria including Trichoderma echinospora,Aspergillus niger,Rhizopus Niger and Penicillium combined with Bacillus subtilis from 2016 to 2019.The disease of wheat scab treated with different straw ripening agents was investigated in 2018 and 2019,respectively.The results showed that the rainfall in the period of heading and flowering of wheat was the key factor.Compared with no straw returning, straw returning had no significant effect on the occurrence of FHB.The combination of Trichoderma echinosporum and Bacillus amyloliquefaciens could reduce the occurrence of FHB to a certain extent in the year of serious occurrence.更多还原
