农作物在生长发育过程中,既需要肥料供给养分,又需要农药控制病虫危害。农药化肥混用既能收到事半功倍、一举多得的效果,又是农业三高(即高产量、高质量、高效益)低耗生产的有效措施。 农药化肥混用,既要发挥药效又要发挥肥效;既不能影响药肥的理化性质,又不能对作物产生有害影响。因此,施用时不能牵强,要做到对症下药、合理施肥。
Crops in the process of growth and development, both need fertilizer to provide nutrients, but also pesticides to control pests and diseases. Mixture of pesticides and fertilizers can not only receive the multiplier effect with multiple benefits, but also the effective measures of low production of three high agricultural (ie high yield, high quality, high efficiency) production. Mixture of pesticides and fertilizers, it is necessary to play a pharmacological effect but also to play a fertilizers; neither can affect the physical and chemical properties of fertilizer, but also can not have a detrimental effect on crops. Therefore, the application can not be far-fetched, to be the right medicine, rational fertilization.
