The crop cultivation technique of ridge-furrow with plastic film mulching can significantly increase the yield and water-use efficiency. This paper reviewed the development and current situation of technology of ridge-furrow cultivation with plastic film mulching， discussed its effects on the yield of several major crops and its mechanisms， and proposed the future development. It was expected to promote the further development of the technology and provide reference for the relevant researches. In the technique of ridge-furrow cultivation with plastic film mulching， a ridge is created， then covered with plastic film; crops are planted between the ridges. The advantages of this technique promotes its application， which are: 1) it improves the effectiveness of soil water. Film mulching over the ridge inhibits surface evaporation and increases soil water content by collecting rain water and condeation of soil water. 2) It regulates the ground temperature. Ridge mulching increases soil temperature， especially at the crop seedling stage， increasing emergence and seedling rates; it also decreases soil temperature during high temperature period， promoting crop growth and development. 3) It improves soil physical and chemical properties， improves soil structure， adjusts soil enzyme activity， and provides a good soil environment for crop growth. However， the mulching film cultivation mode also has certain deficiencies: 1) the development and promotion of the ridge laminating machine is relatively backward. 2) Mulch film cre
