Through many years of effort, the building of agricultural standardization system in Zhejiang Province has made significant achievements, effectively giving play to the technology supporting role of agricultural standardization in adjusting agricultural industrial structure, and promoting the transformation and upgrading of industrial structure. But with the acceleration of the development of modern agriculture in Zhejiang Province, the building of agricultural standardization system poses new opportunities and challenges. This article describes the development course of the building of agricultural standardization system in Zhejiang Province, analyzes the current situation, characteristics and problems, and finally puts forward the following recommendations: improving and coordinating the working mechanism; improving standard system; focusing on demonstration and promotion; improving test and supervision system; focusing on human resources building; increasing capital input.展开更多
