笔者从北京市植物保护站获悉,水肥药一体化技术是将灌溉与施肥、施药融为一体的农业新技术。其借助压力系统,将可溶性固体或液体肥料、农药,通过管道和滴头形成滴灌,均匀、定时、定量的注入土壤,进而被作物吸收,以达到营养作物、防治病虫害的目的。同时其也具有节水、节药、省工的特点,能够减少农业面源污染,满足农业节水需要。 The author learned from Beijing Plant Protection Station, water and fertilizer integration technology is irrigation and fertilization, pesticide application of new agricultural technologies. It uses pressure system to inject soluble solids or liquid fertilizers and pesticides into drip irrigation through pipelines and drippers and inject them evenly, regularly and quantitatively into the soil, which are then absorbed by crops to achieve nutritious crops and control pests and diseases. At the same time, it also has the characteristics of water saving, medicine saving and labor saving, which can reduce agricultural non-point source pollution and meet the needs of agricultural water saving.
