河套灌区膜下滴灌研究进展

Advances in the Study of Mulched Drip Irrigation in Hetao Irrigation District

河套灌区是我国3个特大型灌区之一,也是国家重要的商品粮基地。近年来随着灌溉面积的逐年增加和引黄水量的减少,土壤盐渍化和水资源紧缺的矛盾日益突出。膜下滴灌作为一项先进的节水灌溉技术,在我们西北旱区的农业节水和盐碱地治理中发挥着重要的作用,然而该技术在河套灌区的应用和研究还相对较少。在分析河套灌区农业节水现状的基础上,综述了膜下滴灌技术在该地区的研究进展,重点探讨了膜下滴灌在河套灌区应用前景和下一步研究重点。

As one of the three ultra-large irrigation districts,the Hetao Irrigation District is an important commodity grain base of China.Currently,due to the increase of irrigation area and decrease of water supply from the Yellow River,the contradiction between soil salinization and water scarcity is increasingly becoming outstanding.Mulched drip irrigation,an advanced water-saving irrigation technology,has been playing an important role in the agricultural water saving and saline-alkali soil improvement in arid areas in Northwest China.However,this technology is not very popularly applied and studied in the Hetao Irrigation District.Based on the current situation of agricultural water saving in the Hetao Irrigation District,in this paper,the study advance in mulched drip irrigation is summarized and its application prospects and future research in this irrigation district are mainly discussed.
