Research Progress on Effects of Mixed Fertilization on Maize Production and Soil Ecology
Excessive fertilizer use has shown diminishing returns on maize yield.Improving fertilizer utiliza-tion,enhancing soil quality while maintaining stable yields,and ensuring sustainable agricultural development have become pivotal in the National Agricultural Strategy Action Plan.This paper systematically sorted out the current re-search on the application of straw,new organic fertilizers and various organic nutrients in maize cultivation.It com-prehensively reviewed the effects of various organic measures on maize yield and farmland soil under the condition of fertilizer reduction,providing basic research support for the advancement and dissemination of integrated fertiliza-tion technologies.Finally,at the technical and policy level,suggestions were put forward to improve the comprehen-sive productivity of cultivated land,rely on technology to lead the efficient utilization of fertilizer,and do a good job in regional fertilizer management according to the potential of increasing production.It was emphasized that organic fertilizer after harmless disposal of manure should be included in the priority procurement products of local govern-ment's farmland return implementation projects,so as to promote the sustainable development of local circular agri-culture.
