摘　　要：从多种作物根际土壤中分离的167个菌株及收集的4个细菌菌株中,获得对荸荠枯萎病菌有抑制作用的拮抗菌53株,其中拮抗细菌48株,占90.6%,拮抗真菌5株,占9.4%。选出抑菌圈直径大于30mm的37号、50号、52号3个细菌菌株进一步进行盆栽防病试验,防治效果分别为44.8%、35.5%、34.6%。167 isolates were isolated from different soil samples and 4 bacterial isolates were collected. 53 isolates showed antagonistic activity on Fusarium oxysporum, the pathogen of wilt disease in water chestnut. The number of bacteria isolates amounted to 48 and made up 90.6% of all antagonistic microorganisms. Other isolates were antagonistic fungi, making up 9.6% of all. 3 bacterial isolates with inhibition zone over 30mm were selected to conduct pot-culture in greenhouse tests for water chestnut wilt control...
