摘要
针对宁夏引黄灌区严峻的缺水问题,开展了水稻节水高产控制灌溉技术应用研究。在当地气候条件下,分析了灌溉水量、稻田土壤温度、地下水埋深、土壤水分、水稻产量构成因素等,形成了节水条件下的灌溉模式。结果表明:应用节水控制灌溉技术,可节水36 9%～46 6%,增产10%。
This paper presents water saving and high output control and irrigation technology for nice farmland,which aims at resolving the problem of short water in Ningxia Yinghuang Irrigation District.It analyzes irrigation quanlity,earth temperation the depth of water under earth,moisture of earth and rice preduction etc.at the condition of local weather and it farms irrigation model of water saving.Based on the analysis,it can save water 369%～466% increase output 10% as using water saving irrigation technology.
