摘　　要：回顾了覆盖技术在国内外的发展现状,并对目前在农业生产中应用较多的砂石覆盖、秸秆覆盖、地膜覆盖进行了总结和比较。较详细地列举了不同覆盖技术对土壤水、热、盐的影响。指出了目前覆盖技术中存在的问题及发展方向,旨在促进覆盖技术在农业生产中能够合理地应用。The development status of mulching technology at home and abroad is reviewed, and sand mulching widely used in agricul- tural production and straw mulching and plastic film mulching are analyzed in detail and compared in this paper. In addition, the in- fluence of water, heat and salt in soil by mulching technology is expounded. Meanwhile, some existing problems and related develop- rnent trend in the future of the current mulching technology are pointed out for promoting even more rational use of mulching technol- cv in aricultural production.
