球孢白僵菌 HFW-05菌株在土壤中宿存研究初探
The Preliminary Study of Beauveria bassiana Survived in Soil
摘要
Abstract
In order to research the Beauveria bassiana HFW-05 strain in soil in persistent storage,the soil mix bacteria method had carried on the preliminary exploration.Initial bacterial biomass was 1.0 ×10 7 spore /mL con-centrations.Continuous observation 60 d,the results showed that Beauveria bassiana in soil persistent within two months,a number of colonies showed a downward trend involatility,slower rate of decline,in the release of 30 -60 d,Beauveria bassiana in a stable state of fluctuation,CFU continued in the 10 6 cfu/g.At the same time,the num-ber of soil microorganism population had little effect.There was no significant difference before and after the re-lease,the virulence of Beauveria bassiana against Plutella xylostella,didn′t destroy the original ecological balance.关键词
