Abstract
The limiting factors for getting high yield of crop in dry-land are the fertilization and soil moisture shortage. Experiments were carried out with straw mulch method. The results showed that straw mulch could improve soil fertility, decrease soil volumetric weight, raise soil moisture content, reduce soil erosion, water use efficiency (WUE) increased by 25.5%. Water consumption decreased by 8.6 %, Promote crop growth, crop yield increased by 14.7 %, and raises the benefit of economy, ecology and society.
