摘要
根据苜蓿地下滴灌土壤水分变化 ,并以常规沟灌为对照 ,对苜蓿田间地下滴灌的适宜埋深和灌水量进行了研究。结果表明 ,地下滴灌比常规沟灌的苜蓿 ,鲜草出草率高 ;滴灌带埋深 3 5 比埋深 10 的苜蓿长势好 ,鲜草产量高 ,并初步拟定了苜蓿地下滴灌的灌溉制度。因此 ,苜蓿田实施地下滴灌是可行的 ,在新疆具有推广应用价值和发展潜力。
In this paper,suitable buried depth and irrigation water quantity of underground drip irrigation in clover field are researched according to the soil moisture change of underground drip irrigation of clover field,through comparison with that of conventional furrow irrigation. The results show that the grass production of underground drip irrigation is higher than conventional furrow irrigation; the growth and production of clove of drip irrigation at the buried depth of 35 cm are better than those of 10 cm. Meanwhile,the irrigation schedule of underground drip irrigation of clover is drawn out. Thus,it is feasible to implement underground drip irrigation in clover field,and the technique has a high extension value and a good development potential.
