摘要/Abstract

摘要： 从蔬菜地黄瓜根围土壤中经分离筛选,得到两个对黄瓜枯萎病菌(Fusarium oxysporum f.sp.cucumerinum)有抑制作用,并能明显促进黄瓜生长的菌株ZJY-1(Brevibacillus brevis)和ZJY-116(Bacillus subtilis).将这两菌株与一株毒死蜱降解菌DSP3(Alcaligenes faecali)按照不同组合处理黄瓜种子,以研究多功能菌群在环境中发挥生态效应的可行性.结果表明,这两株具有生防和促生功能的菌株与DSP3按不同组合混合后,对黄瓜的防病促生作用均不受影响.同时对黄瓜根围土中毒死蜱含量检测分析发现,DSP3与这两株细菌混和施用后其降解率与单独施用相比没有明显差异.实验初步证明,不同功能的菌株混合施用后可以发挥其生态效应.

Abstract: In this paper,strains ZJY-1(Brevibacillus brevis)and ZJY-116(Bacillus subtilis)with evident inhibitory effect on Fusarium oxysporum f.sp.cucumerinum and with promotion effect on plant growth were screened from cucumber rhizosphere,and the feasibility of exerting the ecological effects of multifunctional micro-flora agent was studied by treating cucumber seeds with the two strains singly or mixed with chlorpyrifos-degrading strain DSP3(Alcaligenes faecali).The results showed that the two strains could keep their functions in suppressing disease and promoting plant growth when mixed with DSP3,and the chlorpyrifos-degrading effect of DSP3 had no significant difference when DSP3 was applied singly or mixed with the two strains.This study testified the feasibility of applying multifunctional micro-flora agent in the environment.

Key words: Biocontrol agent, Plant growth-promoting microorganism, Pesticide-degrading microorganism, Multifunctional micro-flora
