摘要： 通过田间试验研究了膜下滴灌对棉田生态环境状况及棉花生长发育及产量形成的影响。结果表明，膜下滴灌与常规灌溉相比，覆膜滴灌改变了棉花田间水分环境，为棉花的生长创造了良好的水、肥、气、热条件,有利于棉花生长发育；同时，可以减少地面蒸发,减少灌溉水的深层渗漏, 保持土壤肥力, 提高水分利用率, 增加作物产量，具有良好的经济、生态和社会效益。

Abstract: Field experiments were carried out to study the effects of drip irrigation under mulch film (DIUMF) on soil ecology environment and growth of cotton. The results showed DIUMF changes humidity environment of cotton in the field, creates Beneficial water, fertility, air, hot Condition for the cotton's growth, Comparing with normal irrigation, DIUMF is helpful to decrease soil surface evaporation, increase soil water content, reduce deep leakage, hold soil fertility, enhance water use efficiency, and improve vegetable yield. Have the good economy, ecosystem and social performance.
