In recent years,unreasonable application of chemical fertilizers has brought many soil environmental problems.Studies have shown that organic fertilizer application can not only solve the problem of resource utilization of livestock and poultry breeding waste,but also increase soil organic matter while reducing the application of chemical fertilizers.The application amount of organic fertilizer per mu is large,and the corresponding fertilization equipment needs to be equipped.In view of the current situation that there are many kinds of organic fertilizers with complex physical characteristics and low technical level of application equipment,this paper focuses on the current situation of research and development and application of organic fertilizer application equipment at home and abroad,analyzes the main problems existing in organic fertilizer application equipment in China,summarizes the applicability and characteristics of existing organic fertilizer application equipment,and puts forward reasonable suggestions from the technical and policy levels.The development trend of organic fertilizer application equipment is prospected,which provides a reference for the rational selection of supporting equipment for organic fertilizer application and a certain reference for the high-quality development of organic fertilizer application technology and equipment in the future.
