分析了宁夏引黄自流灌区示范应用水稻控制灌溉技术的节水高产效果。结果表明 ,1961.1hm2 的控灌水稻的产量比常灌水稻增产 519kg/hm2 ,增产幅度为 5.3 % ;灌水次数平均减少 16次 ,灌溉定额平均减少 70 57 5m3/hm2 ,节水 38 4 % ,水分生产效率提高了 65.3% ;稻米粗蛋白含量提高了 0 .2 1% ,整精米率提高了 1.59% ,垩白率和垩白度降低了 1.12 %和 0 .2 9%。此技术的进一步推广可实现宁夏回族自治区 8.67万hm2 水稻田的高产稳产 ,年可增收 790 7.9万元 ,具有显著的节水效果和经济效益 The water-saving and high-yielding effect of demonstration irrigation rice control irrigation technology in Ningxia Yellow River gravity irrigation area was analyzed. The results showed that the yield of 1961.1 hm2 paddy rice was increased by 519 kg / hm2 and the rate of increase was 5.3%. The average number of irrigation was reduced by 16 times. The irrigation quota was reduced by 70 575m3 / hm2, the water saving was 38.4% The production efficiency increased by 65.3%. The crude protein content in rice increased by 0.221%, the milled rice rate increased by 1.59%, the chalkiness rate and chalkiness decreased by 1.12% and 0.29% respectively. The further promotion of this technology can realize a high and stable yield of 86,700 hm2 paddy fields in Ningxia Hui Autonomous Region, with an annual increase of 790.99 million yuan, with significant water saving and economic benefits
