通过不同电导率灌溉水棉花膜下滴灌试验，观察了棉花在生长和产量方面的变化。结果表明，随着灌溉水电导率的增大，棉花的生长呈逐渐变差的趋势，产量也有规律地减少。利用实测资料构建了棉花产量与灌溉水电导率的函数关系，在对其分析的基础上推导出塔里木盆地咸水滴灌对棉花产量影响的阈值。
通過不同電導率灌溉水棉花膜下滴灌試驗，觀察瞭棉花在生長和產量方麵的變化。結果錶明，隨著灌溉水電導率的增大，棉花的生長呈逐漸變差的趨勢，產量也有規律地減少。利用實測資料構建瞭棉花產量與灌溉水電導率的函數關繫，在對其分析的基礎上推導齣塔裏木盆地鹹水滴灌對棉花產量影響的閾值。

The under-mulch drip irrigation experiment has been applied to the cotton fields with water containing different degrees of mineralization (DOM) ,through which to seek some laws on the effect of growth ,quality and yield of cotton in arid land ,Tarim Ba‐sin .The results indicate that the growth ,quality and yield of cotton get worse as DOM of irrigation water gets thicker .The function about the yield of cotton-the DOM of water is constructed according to experimental data .The threshold of the DOM of irrigation water is concluded by analyzing the function .
