我师冬小麦种植面积占粮食作物面积的70%以上,五十和六十年代,亩产徘徊在200—300斤,亩耗水量300—350方.近年来,随着生产水平的不断提高和小麦大面积稳产丰产田的不断涌现,小麦的亩灌水次数和灌水量也随之增加,但水的有效利用系数较低.因此,探明冬小麦中产栽培条件下的灌溉问题,对提高小麦产量和灌溉水效益十分重要. My teacher winter wheat acreage accounted for more than 70% of the area of ​​food crops in the 1950s and the 1960s, hovering at 200-300 pounds per mu, mu of water consumption 300-350 side.In recent years, with the continuous improvement of production levels and wheat Large area of ​​stable yield and high yield fields continue to emerge, the wheat acres of irrigation times and irrigation volume also increased, but the effective utilization coefficient of water is low.Therefore, to explore the winter wheat cultivation under conditions of irrigation problems, to improve wheat yield and irrigation Water efficiency is very important.
