摘　　要：从作物根际土壤中分离筛选出4株对水稻纹枯病菌、油菜菌核病菌、棉花枯萎病菌、棉花黄萎病菌和番茄青枯病菌等重要土传病原菌有较强拮抗作用的拮抗菌,其中芽孢杆菌Bacillus.spp.2发酵液处理西瓜后,具有显著的防病增产作用。Several bacteria strains were isolated from different plant rhizosphere soils,of which 4 strains showed antibiotic activities to 5 kinds of phytopathogens,such as Rhizoctonia solani, Sclerotinia sclerotiorum, Fusarium oxysporium f. sp. vasinfectum,Verticillium dahliae and Ralstonia solanacearum. The antagonism Bacillus.spp.2 greatly increased the yields of watermelon according to the field experiments.
