针对北方井灌区种粮农民投入高收益低的问题,在工程节水的前提下,采取农艺节水技术,以大田实测资料为依据,分析了小麦6个品种在特旱低温灾害年型的生理生态耗水特性和产量性状及节水高效栽培组合模式。试验表明1.63hm2示范田平均浇3.5次水,产量8253.75kg,水分生产率为2.988kg/m3,产出投入比4.11:1,比对照田成本减少11.14%,增产28.35%,耗水量下降23.85%,水分生产率提高69.77%,产投比是对照田的2.96倍,纯收入是对照田的5.86倍,实现了农业增产,农民增收和农村经济走上可持续发展的致富道路。
Aiming at the problem of low income of high-yielding grain farmers in northern well irrigation area, under the premise of water-saving project, agronomic and water-saving technologies were adopted. Based on field measured data, the effects of six types of wheat on physiological Ecological water consumption characteristics and yield traits and efficient water-saving cultivation combination mode. The results showed that the average irrigation water input rate of 1.63hm2 was 3.525kg / m3, output was 8253.75kg, yield was 2.988kg / m3, input-output ratio was 4.11: 1, output decreased by 11.14%, output increased by 28.35%, water consumption decreased by 23.85% Water productivity increased by 69.77%, production-to-investment ratio was 2.96 times of that of the control field and net income was 5.86 times of that of the control field, thus realizing a road to prosperity for agricultural production, rural incomes and sustainable development of the rural economy.
