该文着重研究了旱作农业的首要矛盾和解决旱作麦田的指导思想和入手点.研究资料得出:不论在丰年、平年、歉年,在相同的降雨条件下,县际、社际、队与队、相邻地块之间,甚至同一块地不同地段之间,产量却广泛存在显著差异,其根本原因在于肥.连年施用有机肥的高肥地,比多年不施肥的白茬地,平均单位水量的生产效率提高80-150%,大大提高了水分的利用效率.地 This paper focuses on the primary contradiction of dry farming and the guiding ideology and starting point to solve the problem of dry wheat field.Research results show that in the same year rainfall, The fundamental difference between the team and the team, between adjacent plots, and even between the same plots and the different plots is that there is a wide range of yield differences. The fundamental reason for this is that the high-fat land with organic fertilizers in successive years is more fertile than the non-fertilized stubble , The average unit of water production efficiency increased by 80-150%, greatly improving the water use efficiency.
