Review of the Motivation and Management of"Non-grain"Cultivated Land in China from the Perspective of Agricultural Power
The phenomenon of"non-grain conversion"of cultivated land appears to different degrees in the main grain producing area,main grain marketing area and the production and marketing balance area,which seriously affects the food security of our country and hinders the construction of China's agricultural power.The systematic summary is made by using literature analysis,policy interpretation and induction,in order to provide reference for the formulation of China's agricultural policy theory,help the construction of an agricultural power,and provide help for later academic research.The results suggest that the definition of the concept of"non-grain"of cultivated land has not yet reached a conclusion.This paper proposes that the"non-grain"of cultivated land can be divided into broad and narrow.The"non-grain"of cultivated land in a broad sense refers to the agricultural management behavior that agricultural operators change the use of cultivated land from food pro-duction to all non-grain planting due to economic,political,natural,social and other factors.The"non-grain"of cultivated land in the narrow sense refers to the agricultural production behavior that agricultural operators choose to plant cash crops or other crops on cultivated land in-stead of food crops because of the impact of economic comparative benefits.The driving factors include low comparative benefit of grain farm-ing,industrial and commercial capital to the countryside,land transfer,upgrading of residents'consumption structure and improving educa-tion level of the new generation in rural areas.The rectification measures include adhering to and improving the grain subsidy system,strictly implementing the priority order of cultivated land utilization,guiding and supervising industrial and commercial capital to the countryside,im-proving cultivated land"non-grain"in different regions and following the"Big Food Concept"to optimize the distribution of grain production.
