摘要
田间试验结果表明 ,在茯苓栽培时采用纱网片阻隔、敌敌畏凝胶缓释、敌敌畏硅藻土缓释、辛硫磷硅藻土缓释、辛硫磷毒沙及纱网套袋等方法都能有效控制茯苓喙扁蝽Mezira (zemira)poriaicolaLiu种群数量。其中 ,尤以纱网片阻隔法最好。该方法简便易行 ,可完全不用化学农药 ,而且纱网可使用多年 ,对害虫预防效果持久 。
The result of experiment in the field showed that when the Poria cocos was cultured, population amount of Mezira (zemira) poriaicola Liu could be controlled effectively by many methods, such as obstruction with a slice of yarn net, DDVP gel slow release; DDVP diatomaceous earth(E.D) slow release, phoxin D.E slow release , phoxin poison sand, the covering bag of yarn net and so on . Among them obstruction with a slice of yarn net is especially the best.This method is simple and need not use any pesticide and has long effect of the pest prevention. At the same time, it has no bad influence on the growth of hypha and sclerotia of Poria cocos.
