大面积提高粮食单产:理论逻辑、现实制约与实现路径
Large-scale increase of grain yield per unit area:theoretical logic,realistic constraint and realization path
摘要
Abstract
To comprehensively consolidate the foundation of food security means ensuring food security at a higher level and with higher quality.In the era when the grain planting area is at a historically high level,it is necessary to attach great importance to the grain yield per unit area in improving grain production capacity and ensuring national food security,and to strengthen the rele-vant research in this field.At the policy level,there is a theoretical logic to increase grain yield in a large area,mainly including security logic,economic logic and scientific logic,which means there is demand at the security level,value at the economic level,and realiablity at the scientific and technological level.The important restricting factors are multi-dimensional including five as-pects:low-quality and degraded cultivated land,poor development and popularization of high-qulity seeds,insufficient technical support,less promotion of advanced agricultural machinery,and the weak policy system to encourage grain yield increase.In view of the constraints existing in reality,it is necessary to fully stimulate the positive role of"good farmlands,good seeds,good methods,good machinery and good system"to realize the substantial increase of grain yield per unit area through the combination of"five good",thus achieving a new round of 100 billion tons of grain production capacity.关键词
