摘　　要：通过对高寒干旱区甜菜膜下滴灌的灌溉制度的试验研究,摸索出生育期有效降雨量在467.5mm以上湿润年膜下滴灌综合效果最好的是生育期灌一水的处理,滴灌定额30m3/667m2,灌水时间为4月20日,其次是灌二水处理。鉴于不同水文年甜菜的灌溉制度有所不同,尚需进一步研究明确。Through experiments on drip irrigation under film mulching of sugarbeet, we found that the best treatment was irrigating once in growing period of rainy year when effective rainfall was more than 467.5 mm, drip irrigation quota 30 m3/667m2, and irrigation time on April 20; second treatment is irrigating twice. Further research will be need further because of the irrigating system was different in different hydrological years.
