摘　　要：为了确定4种生物制剂Y1、Y2、Y4和Y5对大豆根腐病的田间防效和对大豆叶片生理指标的影响,通过田间小区试验,从对大豆根腐病病情指数和生理指标方面进行考察。结果表明,4种生物制剂苗期防治效果分别在40%～75%、45%～50%、38%～48%和40%～50%之间,与对照比,大豆叶片中游离氨基酸(TFA)、可溶性糖(SS)和叶绿素含量(CC)都有显著增加,而脯氨酸(Pro)的含量下降。Using field plot test, the antagonism of four Biological reagents（ Y1 ,Y2 ,Y4 and Y5 ）on Soybean root rot and the effect of soybean leaf physiological index were tested from soybean root rot disease index and physiological index.The results suggested that the control effects were 5%-40% ,45%-50% ,38%~48% and 40%-50%, and the contents of free amino acids,soluble sugar and chlorophy 11 were higher by comparing with control, the content of free praline were lower.
