| 摘 要： | 通过嘉峪关工务段黑山湖防沙工区铁路防风固沙林二白杨、灌木柳等树种的地下滴灌试验,对其灌水量、水分运动等指标进行了计算与分析,初步确定了合理的灌水量、灌水时间和灌溉周期.试验结果表明:滴灌每次灌溉时间为10 h,每公顷防风固沙林带地下滴灌年灌水定额为6 135 m3,每次灌溉定额306.75 m3;全年灌水时间分别为4～9月每月灌溉3次,10月下旬灌越冬水1次,灌溉时间为20 h.

| Abstract: | This paper,based on the trials using drip-irrigation on sand-fixation species Populus gansuensis and bush-willow in Heishanhu section of Lanxin railway,analyzed the irrigation quota and water movement of the species,and preliminarily specified the rational irrigation quota,duration and frequency.The results showed: for sand-fixation windbreaks,10 hours are needed in each irrigation using drip-irrigation,the annual irrigation quota is 6 135 m~3/hm~2 and the irrigation quota for each time is 306.75 m~3.The species should be irrigated from April to September and 3 times in each month.Winter irrigation is in the late of October and it needs lasting 20 hours. |
