摘　　要：以美国红提葡萄为试材,根据其在不同生育期的需水规律,以灌水次数、灌水周期、灌水定额为试验因素,对非耕地日光温室葡萄滴灌灌溉制度进行了研究。温室葡萄全生育期为228d,各生育期的灌水定额设有150、300和450m^3/hm^2 3个水平,灌溉周期设置16、20和25d3个水平,试验共设6个处理,每个处理3个重复,共设18个试验小区。经过灌水要素的优化选择,在滴灌条件下全生育期内最优平均灌水次数为14次,灌水周期为16d,次均灌水量310.71m^3/hm^2,适宜灌溉定额4 350m^3/hm^2,产量达到3.49万kg/hm^2。Based on water requirement law of grapes in different growth stages, this paper studied drip irrigation schedule of grape with different irrigation times, cycle and irrigation quota by complete combinational design in the sunlight greenhouse. The growth stage of grapes in the sunlight greenhouse continued 228 days. The irrigation quota of each growing period was respectively set to be 150, 300, and 450 m3/hm2 , the irrigation cycle was respectively set to be 16, 20 and 25 d. The test was conducted with 6 treatments, 3 times repeat and total 18 plots. The optimal irrigation scheme is 14 watering times, 16 days irrigation cycle with the irrigation quota of 310. 71 m3/hm2 and irrigation norm of 4 350m3/hm2 during the whole period. The production can reach 34 900 kg/hm2.
