摘　　要：利用生防菌生产菌剂是目前防治根结线虫的重要措施之一。单一菌剂的施用易受土壤中复杂生态因子的影响,各种生防菌相互作用可提高根结线虫防治效果的稳定性。研究了芽孢杆菌B16对根结线虫生防真菌厚垣普可尼亚菌ZK7产孢能力的影响,并初步分析了相关信号物质。结果表明,芽孢杆菌B16能显著提高厚垣普可尼亚菌ZK7的产孢能力,B16发酵液与ZK7发酵液共培养产生的丁内酯能促进ZK7产孢,产生的甲苯对ZK7的产孢能力没有促进作用。Biocontrol agent is one of the most important measures to control Meloidogyne spp..The application of single biocontrol agent is easily affected by the complex ecological factors in the soil,and the interaction of various biocontrol agents improves the stability of Meloidogyne spp.control effect.In this paper,we studied the effects of Bacillus nematocida B16 on the sporulation capacity of Meloidogyne spp.biocontrol fungi Pochonia chlamydosporia ZK7,and preliminarily analyzed the correlation signal substances.The results show that B.nematocida B16 can significantly increase the sporulation capacity of P.chlamydosporia ZK7.The sporulation of ZK7 can be increased by butyrolactone produced in the co-culture of B.nematocida B16 fermentation broth and P.chlamydosporia ZK7 fermentation broth,but toluene has no promotion effect on the sporulation capacity of P.chlamydosporia ZK7.
