试验就荒漠地区葡萄灌溉方式、灌溉量对葡萄生长发育的影响进行了初步研究。试验表明 ,荒漠地区使用滴灌比沟灌能够减少用水量 5 0 %以上 ,产量提高 17% ,含糖量提高 1.9%。经过相同时间后 ,滴灌土壤含水量高于沟灌 1.9%～ 2 .5 %。通过观察水分在土壤中的运动 ,确定葡萄单次的最佳灌溉量。

The experiment of the effects of different irrigation methods and water volume on the growth and development of grapes in arid-desert areas was preliminarily conducted. The result showed that drip irrigation could save water by 50% as compared with ditch irrigation, and fruit output increased by 17%,sugar content increased by 1.9%. After same time, soil moisture could rise by 1.9%-2.5% compared with ditch irrigation. By watching the movement of water in soil, we can decide proper irrigation quota of one time.
