[Ecological effects of multifunctional micro-flora agent in environment].
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.
