木霉生防菌对大豆幼苗的促生作用及对根腐病的防治效果OA
The Promoting Effects and Control of Root Rot on Soybean by Trichoderma Biocontrol Strains
[目的]研究木霉菌对大豆幼苗的促生作用及对根腐病的防治效果.[方法]用6株木霉菌剂处理土壤进行盆栽试验,测定大豆植株的形态指标及根腐病的发生情况.[结果]供试木霉菌株均能促进大豆植株生长,其株高、茎粗、根长、干物质积累均比对照增加.木霉菌株制剂均可减轻根腐病的发生,当浓度为5×108个/g时防效均在70％以上.不同菌株对大豆植株的促生和对根腐病的防治效果不同.[结论]木霉菌能促进大豆的生长和降低根腐病的发生.
