新疆化肥投入量与粮食增产潜力的研究

随着新疆人口不断增长,对粮食的消费也在不断增加,根据新疆1980~2004年化肥施用量和作物产量,以粮食作物为主要研究对象,从不同年份单位播种面积的粮食产量和肥料施用量变化,求出相应的单位播种面积可能达到的粮食生产潜力,并以此为基础计算出新疆单位播种面积的粮食增产潜力。并为保证新疆的粮食安全提出了相应的对策。研究表明:新疆粮食单产与单位面积施肥量之间呈现显著的相关关系,粮食单产还有一定的增产潜力,增施化肥的增产效率也较高。

Research of Fertilizer Inputs and Grain Yield Potential in Xinjiang

With the continuous growth of the population in Xinjiang,the grain consumption has also been increased.According to chemical fertilizer and crop yield of Xinjiang in 1980-2004,grain is regarded as a major research object.The grain prduction potential was calculated based on change of grain yield and fertilizer application in different years.Meanwhile,in order to guarantee food security in the region,it was suggested that appropriate measures should be taken.The research showed that there is significant correlation between fertlizer application and grain yield per unit area.The grain yield potential is high,increased fertilizer yield is higher effectively.
