棉花膜下滴灌节水技术的推广,改变了大水淹灌条件下的棉花生产方式和棉田的生态环境,提高了棉花的产量、品质。但是,增加了棉花害虫防治工作的难度。因此,生产中应根据棉花膜下滴灌技术的特点,因地制宜地调整棉花害虫防治技术,才能有效地控制棉花害虫,充分发挥滴灌技术效应,促 The popularization of cotton drip irrigation and water saving technology has changed the production mode of cotton and the ecological environment of cotton under the condition of flooded irrigation and increased the yield and quality of cotton. However, it has increased the difficulty of cotton pest control. Therefore, cotton production should be based on the characteristics of drip irrigation technology, according to local conditions to adjust the cotton pest control technology in order to effectively control cotton pests, give full play to drip irrigation technology, and promote
