摘要
通过查阅大量文献资料,综述了滴灌与覆膜滴灌技术在国内外的应用情况,结合野外试验分析与探讨了(覆膜)滴灌条件下的土壤水盐运移特征、(覆膜)滴灌对植物根系的影响,最后针对塔里木河下游极端干旱区滴灌防护林种植中节水、压盐灌溉技术的难点及需要解决的问题提出了展望,认为为提高极端干旱区防护林成活率等,可以将覆膜技术与滴灌技术相结合用于1~3年的防护林种植中。该研究希望能为干旱、半干旱区绿洲的可持续发展提供理论依据。
On the basis of a great deal of scientific literatures, the application of drip irrigation anti nmlch drip irrigation technology at home and abroad were reviewed. Soil water-sah transport characteristics under （much-cover） drip irrigation condition and the effect of the （ much- cow^r） drip irrigation on plant root were analyzed based on a great deal of scientific literatures and field experiment. In the end, this paper put forward the prospects relating to the technology difficuhy in shelterbelt planting in the extreme arid areas in lower reaches of Tarim River. Re- search suggested that to enhance the survival rate of shelterbelt in extreme arid areas, the coated technology combined with drip irrigation tech- notngy can be applied in the planting of I -3 -year shelterbelt, which aimed to provide a theoretical basis for the sustainable development of arid and semi-arid area oasis.
