在二点委夜蛾重发地,小麦收获后立即用玉米秸秆还田机将麦残体分别粉碎1遍和2遍后还田,以小麦收获后麦秸直接散落在田间为对照( CK),研究了粉碎麦秸对夏玉米田二点委夜蛾的防治效果。结果表明:粉碎麦秸人为破坏了二点委夜蛾成虫的活动和产卵环境,能明显降低田间幼虫数量,对二点委夜蛾的防治效果达到85%以上,是1项防治二点委夜蛾简便、易行、省工、节时、有效的农业措施,且利于秸秆腐烂和农事操作。麦秸粉碎1遍对二点委夜蛾就有较好的防治效果(87.85%),粉碎2遍效果(90.38%)更佳。
在二點委夜蛾重髮地,小麥收穫後立即用玉米秸稈還田機將麥殘體分彆粉碎1遍和2遍後還田,以小麥收穫後麥秸直接散落在田間為對照( CK),研究瞭粉碎麥秸對夏玉米田二點委夜蛾的防治效果。結果錶明:粉碎麥秸人為破壞瞭二點委夜蛾成蟲的活動和產卵環境,能明顯降低田間幼蟲數量,對二點委夜蛾的防治效果達到85%以上,是1項防治二點委夜蛾簡便、易行、省工、節時、有效的農業措施,且利于秸稈腐爛和農事操作。麥秸粉碎1遍對二點委夜蛾就有較好的防治效果(87.85%),粉碎2遍效果(90.38%)更佳。

The experiment site was selected in P.lepigone seriously-occurance area.Wheat residue crushing machines were used to crush wheat residue one and two times instantly after wheat harvesting.The objectives of this study were to investigating the control effect of crushing wheat residue on P.lepigone, compared with straw directly return to fields ( CK) .The results showed that crushing wheat residue could disturb spawning environment of P.lepigone and also declined the number of larvas in the fileds, the control effect could reach 85% or higher. Residue crushing was an easy, labor-saving, time-saving and effective agricultural measurement, crushing one time could reach a good control effect (87.85%) and crushing two times could reach higher (90.38%) .
