“四统一”,即节水、省肥、高产、简化的统一。经试验研究和大面积示范证明,亩产量指标500～550公斤的前提下,与传统的高产栽培技术实现同样的产量指标相比,每亩节省灌溉水100立方米,养分施入总量低32.7％～50.3％。氮素当季利用率达60％左右,氮肥当季利用率较全国平均值提高50%左右。现将此栽培技术介绍如下:1 底墒水调节土壤贮水 两米土体是小麦的根系带。播前,通过灌水使 “Four unities,” that is, water conservation, fertilizer, high yield, simplified unity. The experimental research and large-scale demonstration shows that under the premise of yield of 500-550 kg per mu, compared with the traditional high-yield cultivation techniques to achieve the same yield index, the irrigation water saved per 100 mu is 100 cubic meters and the total amount of nutrients applied is 32.7 % ~ 50.3%. Nitrogen utilization rate of about 60% of seasonal utilization of nitrogen fertilizer season than the national average of about 50%. Now this cultivation techniques are as follows: 1 at the end of moisture water regulation soil water two meters of soil is the root system of wheat. Before sowing, make it through irrigation
