| 摘 要： | 对当今我国广泛应用的覆盖种植技术─秸秆覆盖免耕和薄膜覆盖栽培研究表明,在这两种耕作栽培措施下每年可节水20～40mm.节水数量虽然不大,但苗期的土壤水保持着较高能量水平,为提高产量打下良好基础,而从水利用效率角度分析,实际节水每年可达60～200mm,效益更为显着.

| Abstract: | The research on straw mulching by no-tillage and on film mulching declared that 20-40mm water was saved per year.This was a small quanlity,but the soil water potential at the early stage of plant growth was kept higher,and this provided a good condition for high yield.From viewpoint of water using efficiency,the water quanlity saved reached 60-200mm. |

| Keywords: | straw mulching by no-tillage film mulching cultivation soil water balance water using efficiency |
