It was found: 1 The film restrained evaporation surface intensity and had obvious function of rising and keeping moisture, 2The drip irrigation could supply water according to growing requirement and augment of water conflux intensity around crop root, it also had strongly controllable operation and wasted fewer water.

覆膜抑制了土壤表面的蒸发面汇，具有明显的提墒保墒作用，滴灌能随时根据作物生长需要及作物根系汇流强度的增大而补充汇流源，可控性很强，水的浪费率很低。

In order to know the effects of mulch-drip irrigation on soil enzyme activities of saline-sodic soil with shallow water table, activities of alkaline phosphatase, urease, and invertase around the dripper, within 30 cm in horizontal direction and 40 cm in vertical direction from the dripper during the reclamation process, were investigated. Changes and distribution of soil enzyme activities, also their relationships with principal soil environment factors were studied.

为了解地下水浅埋区重度盐碱地覆膜滴灌对土壤酶活性的影响，测定了重度盐碱地在滴灌利用过程中距离滴头不同水平位置（0～30 cm）和垂直深度（0～40 cm）的土壤碱性磷酸酶、脲酶和蔗糖酶活性，并对土壤酶活性的变化、空间分布特征及与土壤环境因子之间的相关关系进行分析。
