中国粮食增产潜力主要影响因素分析

该文从增加粮食播种面积与提高粮食单产两方面,综合分析了影响我国粮食增产潜力的11个主要因素。研究结论认为:粮食单产依然是今后几年影响我国粮食生产的最重要因素;粮食播种面积对粮食生产的影响程度在逐年加强,有可能在不久的将来,替代单产成为第一主要因素。自然环境因素、有效灌溉面积、国家政策、农业劳动力素质、农业机械化水平、生物防控技术和化肥使用量等,也都是影响我国粮食生产的重要因素。

ANALYSIS OF MAJOR FACTORS INFLUENCING GRAIN YIELD INCREASING POTENTIAL OF CHINA

From the 2 aspects of increasing grain sowing areas and improving grain yield per unit area,this paper analyzes 11 major factors influencing grain yield increasing potential in China.Research conclusion indicates that the grain yield per unit area is still an important factor influencing future grain production in China.The influencing degree of grain sowing areas to grain production is increasing year by year.It may probably replace yield per unit area and becomes the Number one factor in the near future.Nature environment factor,effective irrigation area,state policy,quality of agriculture labor force,level of agriculture mechanization,bio-control and prevention technology and quantity of chemical fertilizer application,etc.are also important factors influencing grain production in China.
