摘　　要：利用免耕垄作覆盖技术提高耕地抗旱能力是解决灌溉问题的又一条途径。根据水稻采用免耕垄作覆盖技术进行全旱栽培，能在一般干旱下免灌取得高产的初试成果，证明该技术能建立和保持良好土壤结构状态，充分储蓄利用天然降雨，减少蒸发，防止水土流失，从而提高耕地自肥能力和抗旱能力．实现稳产增收和省水、省肥、省工。The rain-feed and ridge culture covering technology for enhancing drought resistant capacity of cultivated land and another way for solving irrigation problem. According to the experiments, the all dry culture of rice by using of the rain-feed and ridge culture covering technology can be used in a normal dry year and a high yield can also be achieved. The experiments show that the fine soil structure can be established and maintained, natural rainfall can be stored and sufficiently used, evaporation can be reduced, and water and soil erosion can be avoided so that the self-fertilized and drought resistant capacity can be enhanced and the multi-benefit of stable yield and water, fertilizer and work-days savings can be reached.
