YE Hong wei (Qingyang Institute of Agricultural Sciences, Xifeng, Gansu 745000, China)
Aiming at the characteristics of water shortage, unevenly distributed precipitation and large amount of evaporation in dryland farming area, this paper has summarized a series of techniques including; early plowing, deep plowing,slope land terracing, furrow planting, contour planting, year around plastic film mulching, moisture keeping by harrowing and rolling, chemicals application, etc. The practice of these techniques functions positively in stabilizing dryland agriculture development by conserving rainfall and restraining moisture evaporation.
