摘要
基于监测数据及统计资料,总结分析了近30年河南省小麦主要病虫草害发生演变特点。结果表明,河南省小麦病虫草害种类多,主要病虫害发生为害严重。1991年以来,小麦纹枯病、白粉病、蚜虫、麦蜘蛛等持续发生为害较重,赤霉病、叶锈病等上升为主要病害,条锈病近年呈回升态势,地下害虫、吸浆虫等发生为害呈下降趋势。此外,在黏虫、黑穗病等病虫基本得到有效控制的同时,茎基腐病、孢囊线虫病等新病虫出现、发生范围扩大。麦田杂草发生为害严重、优势种群发生变化。根据病虫害发生为害的新特点,提出了针对性的监测预警措施。
The spatial and temporal trends of the main wheat diseases, pests, and weeds in Henan Province in the past 30years were analyzed with systematic monitoring data. There was a wide variety of wheat diseases, insect pests, and weeds in Henan, and the major of them had caused serious losses. Since 1991, wheat sheath blight, powdery mildew, aphids, and wheat mites have continued to occur seriously, and head blight and leaf rust have become the main diseases. Stripe rust showed a resurgence in recent years while the occurrence of underground pests and wheat midge declined. New diseases,insect pests, and weeds continue to appear. Wheat weeds caused severe damage, and the dominant populations have changed. According to the occurrence pattern of diseases and pests, the monitoring and early warning measures towards wheat pests were put forward.
