| 摘 要： | 选择不同熟性的棉花品种,分别设置不同灌水量和灌水次数,进而确定河西走廊棉区最适宜种植的棉花品种熟性及最有效的灌水方式.结果表明,全生育期灌6次水会引起中、晚熟棉花品种贪青晚熟和减产,灌2-3次水不能满足各棉花品种生育期对水分的需求.以中熟品种灌4次水产量达2335.5kg/hmz,经济收益29865.3:g/hm2为最佳处理,与其它处理相比可节水1100-2100m3/hm2,达到了较好的经济收益和节水效应.

| Abstract: | In this study,we selected different maturity cotton varieties and different irrigation times,for choice appropriate cotton varieties and irrigation times in Gansu Hexi cotton cultivated area.The results showed that 6 times irrigations leaded to low yield and extended the growing days of middle and late maturity cotton varieties.2 or 3 times irrigation could not satisfied water need of cotton growing.4 times irrigation is appropriate for middle maturity cotton variety which yield is 2335.5 kg/hm2 and economi... |
