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 (SBDI) 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.

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45 mm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）（P<0.05）；WUE在灌水定额为45 mm时达到最大值0.94 kg·m-3；因此，试验区附近浅埋式滴灌苜蓿适宜的灌水定额为45 mm、灌水周期7~10天。
