辽宁省玉米化肥减量增效施肥技术模式研究

Fertilizer Reduction and Efficiency Increase Technology of Corn Fertilizer in Liaoning Province

针对辽宁省玉米生产中化肥施用量高,利用率低,施肥差异大等问题,提出了减量施肥关键技术,包括总量控制、配方施肥和水肥一体化,从秸秆机械粉碎腐熟还田、增施有机肥、增施碳基肥料几方面,介绍了土壤改良培肥技术。

According to the problems of high fertilizer application,low utilization ratio and great fertilization differences,we put forward the key technology of fertilizer reduction and efficiency increase,including total quantity control,prescription fertilization,and integration of water and fertilizer. Soil improvement fertility technology was introduced from the aspects of straw mechanical crushing and rotten for field returning,applying organic manure,increasing carbon fertilizer application and so on.
