摘　　要：通过田间试验评价了生物肥料"宁盾"对大豆疫霉病的防效及对毛豆的促生作用。结果表明,与对照组相比,不同用量"宁盾"处理后,大豆出苗率无显著差异,甲霜灵锰锌处理则降低了大豆的出苗率。"宁盾"不同用量对A地大豆疫霉病均有一定的防治效果,以450L/hm^2用量防效最好,为36.54%。"宁盾"对大豆亦有较好的促生作用,尤以450L/hm^2用量最佳,A地和B地叶面积平均增量19.04%,株高平均增量23.40%,产量平均增量89.32%。化学农药甲霜灵锰锌对大豆疫霉病基本没有防治效果,对毛豆也没有促生作用。The control efficiency on Phytophthora sojae and growth promoting effect on soybean of bio-fertilizer ＂Ningdun＂ were studied in field.The results showed that there were no significant difference between CK and ＂Ningdun＂ treatments of different dosage on soybean seedling emergence rate,but the rate of metalaxyl mancozeb treatment was lower.Different dosage of ＂Ningdun＂ on Phytophthora sojae had certain control efficiency in A field,and 450 L/hm2 treatment had the best control efficiency with 36.45%.There were also better growth promoting effect on soybean of ＂Ningdun＂,especially the 450 L/hm2 treatment had the best effect.The average increment of leaf area,plant height,yield of A and B field were 19.04%,23.40%and 89.32%respectively.There were no control efficiency on Phytophthora sojae and no growth promoting effect on soybean of metalaxyl mancozeb.
