| Abstract: | The review on crop water use efficiency (WUE) is summarized in this paper. On the basis of elaborating the connotation of crop WUE, The influencing factors of crop WUE including crop, environment, chemical material, planting and other farming measures are analyzed. Among them, the soil and chemical material are discussed in detail. The improvement ways of crop WUE are also discussed, including optimizing growing pattern, selecting species with water-saving & yield-high; farmland mulching; coupling of irrigation water and fertilizer; chemistry regulation and controlling technology; irrigation technology and so on. |
