摘要
从西瓜和柑桔等作物根际中分离到的 B11、B14、B19和 B2 4等芽孢杆菌菌系对水稻纹枯病菌的生长和菌核的萌发有较强的抑制作用。其中 B11和 B14对水稻纹枯病的防治有一定的效果。它们在室内的防效分别是 6 0 .5 %和 6 7.4% ,在大田的防效分别为 5 4 .6 %和 5 2 .1%。
bacteria strains (Bacillus sp.), isolated from rhizosphere of water melon and citrus, inhibit the growth and sclerotia germination of Rhizoctonia solanii These strains were also tested as a biocontrol agent against sheath blight of rice in the greenhouse and field. The result showed that the disease was reduced by 60.5% and 67 4% in greenhouse and 54.6% and 52.1% in the field by B 11 and B 14 respectively.
