上周，由于高溫少雨造成棉苗病蟲害發(fā)生較快，目前田間以蚜蟲為主，棉農(nóng)的主要任務(wù)是噴灑農(nóng)藥控制病蟲害的發(fā)生。據(jù)當(dāng)?shù)孛揶r(nóng)表示，截至目前，棉農(nóng)已噴灑農(nóng)藥2-4次，棉苗病蟲害得到控制，有減輕跡象，棉苗生長正常。
本周，據(jù)天氣預(yù)報顯示，最高溫度周一晴34攝氏度、周二晴37攝氏度、周三多云36攝氏度、周四多云32攝氏度、周五多云29攝氏度、周六雷陣雨25攝氏度、周日小雨28攝氏度，未來幾日持續(xù)高溫，棉農(nóng)仍需繼續(xù)加強田間管理，主要是噴灑農(nóng)藥控制病蟲害的加重對棉花生長的影響，從而保證棉花的正常生長。
