| 摘 要： | 对１１株根际细菌进行自然病土温室防治大豆孢囊线虫筛选试验，得到防效较高菌株４株，防效为：ＪＮＪＱ１－Ｐ（１），７１．８％（ｐ＝０．０１）；ＪＮＪＱ１－Ａ５－１，６９．３％（ｐ＝０．０１）；ＳＹ－ＮＳ，６５．８５％（ｐ＝０．０５）；ＱＳＧ－ＬＤ－６，５７．５％（ｐ＝０．０５），前３株菌的除菌发酵液对大豆孢囊线虫二龄幼虫致死率在９９．６％以上。

| Abstract: | Some rhizobacteria were chosen to test their ability to suppress soybean cyst nematode in matural soil which had been infested by SCN for several years (50 cysts/100g dry soil) in the greenhouse. Four of them, namely JNJQ 1-P(1),JNJQ 1-A 5-1 , SY-NS and QSG-LD-6, showed promising control efficacy, the number of SCN on soybean roots was re ducedover 71.8% (p=0.01),69.3% (p=0.01), 65.8% (p=0.05) and 57.5% (p=0.05) by those 4 isolates. The second stage juveniles of SCN were killed when treated with fementation solution of four bacteria above 93.3%. |
