| 摘 要： | 为了探明新疆阿勒泰地区浅埋式滴灌(Shallow buried drip irrigation SBDI)苜蓿(Medicago sativa‘Algonquin’)的适宜灌溉制度,进行了定周期、变定额的浅埋式滴灌试验,结果表明:浅埋式滴灌处理(shallow buried drip irrigation treatments SBDIT)中灌水定额45mm和52.5 mm的苜蓿干草产量及灌溉水利用系数(Water use efficiency WUE)均显著高于地面灌(Flood irrigation FI)(P0.05);WUE在灌水定额为45mm时达到最大值0.94kg·m-3;因此,试验区附近浅埋式滴灌苜蓿适宜的灌水定额为45mm、灌水周期7~10天。

| Abstract: | Field irrigation experiments with fixed irrigation frequency and changed irrigation quota were carried out to ascertain proper irrigation program of alfalfa irrigated with shallow buried drip irrigation (SB-DI) in Altay Xinjiang.The results showed that:The hay yield and water use efficiency of 45 mm and 52.5 mm irrigation quota of SBDIT were significantly higher than that of flood irrigation (FI) (P＜0.05).Water use efficiency (WUE) of SBDIT reached the highest (0.94 kg · m-3) when irrigation quota was 45 mm.Appropriate irrigation quota of alfalfa irrigated with SBDI nearby the experimental site should be 45 mm,and appropriate irrigation frequency should be 7～10 days. |
