近年来,玉米栽培技术水平的不断提高,施肥对玉米产量的影响已经越来越大,掌握玉米合理施肥的原则和方法对提高施肥水平及玉米高产增收起着至关重要的作用。1%施肥的原则1.1%有机肥与化肥配合施用原则有机肥与氮磷钾化肥配合施用,不仅增产,而且能够培肥地力,提高农田中氮磷钾养分含量,有利于稳步、持续和协调地提高粮食产量。施用氮磷钾等化肥,除补足当季作物吸收带走的养分外,还使土壤中速效养分含量增加。1.2%合理施用氮磷钾比例原则据多年来高产地块农户施肥状况调查及肥效
In recent years, the level of corn cultivation technology continues to increase, the impact of fertilization on corn production has become increasingly larger, master the principles and methods of corn fertilization to improve fertilization and increase yield of corn plays a crucial role. 1% Principle of Fertilization 1.1% Principle of Compounding Application of Organic Fertilizer and Chemical Fertilizer The combination of organic fertilizer and NPK fertilizer not only increases yield, but also fertilizes soil fertility and increases NPK nutrient content in farmland, which is conducive to steady, consistent and coordinated development Increase food production. Nitrogen, phosphorus, potassium and other fertilizers, in addition to make up seasonal nutrients to absorb nutrients, but also to make available soil nutrient content increased. 1.2% Reasonable application of nitrogen, phosphorus and potassium ratio principle According to years of high yield plots of fertilizers survey and fertilizer efficiency
