特旱低温灾害年小麦节水高效栽培模式试验

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.

The Plant Pattern of Wheat with Water Saving and High Efficiencyin Year of Severe Drought and Low Temperature

to solve the problem of High input and low income in northern well irrigation area, we applied Agriculturally water saving technique based on the data from the field and analyze water using and yield characteristics of 6 varieties of wheat on physiological and ecological level. The results showed that in the field of 1.63hm2, watering 3.5 times yield of 8253.75kg is obtained, and the ratio of water producing is 2.988kg/m3. The rate of yield to input is 4.11:1. The cost of money is 11.14% lower and the water needed is 23.85% lower than CK, while its yield is 28.35% higher and the ratio of water producing is 69.77%higher. The ratio of income to input is 2.96 times higher than CK, and the pure income is 5.86 times higher. This result actualized increase of agricultural production.
