摘　　要：新疆自治区实行膜上灌的实践证明：膜上灌与膜侧沟灌相比节水３０％～５０％，且各种作物增产都在１０％以上。目前推广膜上灌的主要形式有：开沟扶埂膜上灌、平铺打埂膜上灌、翘边扶埂膜上灌、河内膜上灌、膜缝灌、平铺压边小块田内膜上灌等。膜上灌水技术，适应范围广泛。应用这种灌水方法，作好平整土地，施足基肥，进行化学除草，化学药控株高，入膜流量的控制，适时打孔增眼及余水的处理，则是膜上灌节水增产的技术保证。It has been proved through the extension of rrigation over pored plasticfilm practice that irrigation over pored plastic film can save 30%～50%of irrigation water with the yield increase of over 10%as compared with furrow irrigation by side poredplastic film. At present,the major patterns over pored plastic film are irrigation byopening ditches with pored plastic film mulching the ridges,irrigation by supportingpored plastic film mulching ridges,irrigation through ditches with proed plastic filmsand irrigation in the plots with pored plastic mulching,etc.Irrigation over pored plasticfilm is adaptable to a wide range. Accordingly,levelling the land,applying more basefertilizer to the land,controlling weeds and plant heights by chemicals and increasingholes by punching in time,and treating excessive water over pored plastic film multch-ing are the technical guarantee for water-saving irrigation.
