| 摘 要： | 为探索牧草有机生产模式下的粘虫(Mythimna separata Walker)防治,对有机牧草种植区和非有机牧草种植区的5种牧草,通过生物农药BT、农业防治即时刈割利用牧草和化学合成农药溴氰菊酯、辛硫磷处理,进行草地上的粘虫防治试验。结果表明:生物农药BT防效与常规农药校正防效无显著差异,校正防效达到91.67%～98.59%;其次为即时刈割利用牧草,校正防效达到52.78%～81.35%,该法与有机生产理念高度吻合,可作为有机牧草生产中首选的防治方法之一。

| Abstract: | To explore the controlling methods of Mythimna separata Walker under a forage organic producing mode,different treatments such as biological control(biopesticide BT),cultural control(immediately mowing),chemical control(pesticides deltamethrin and phoxim) were investigated using comparative experiments in five kinds of forage grass field.Results indicated that the adjusted controlling efficiency of Mythimna separata using biopesticide BT was 91.67%~98.59% which is similar to that using chemical pesticides.T... |
