Development process and trend of medium and low yield field reconstruction in Shaanxi Province

The transformation of medium and low yield grain fields is an important part of cultivated land regulation, which is basically consistent with the requirements of high standard farmland construction. The cultivated land consolidation has experienced from overcoming the single limiting factor to exploring the integrated factors combining the adjustment of ownership and then to the ecological landscape construction target, which has put forward different requirements on the engineering construction, land capacity improvement and management organization innovation integration of cultivated land consolidation. At present, the concrete measures of land leveling, irrigation and drainage, field road and forest protection network have been studied in the field engineering construction of medium and low yield grain fields in Shaanxi province. In the aspect of soil fertility improvement, effective measures such as ditch treatment, soil fertility improvement, soil layer recombination and crop optimization were studied. In the aspect of management organization innovation, the research of property right model combining different yield reform mode and different cultivated land consolidation mode has promoted the optimization and transformation of medium and low yield grain fields in different degrees.
