反坡梯土保水保肥及增产效果研究

Study on Conservation of both Moisture and Fertility and Incresing Effect of Terraced Farmland Construction on the Arid Hillside Land

连续 6年的试验研究表明 ,在旱坡地上修建反坡梯土 ,具有保水、保土、保肥和增产的作用 ,能够将旱坡地面上的冲刷水变成地下渗透水 ,确保反坡梯土内的肥水肥土不被冲刷流失 ,把“三跑土”变成“三保土” 。

A six year study on the hold moisture,conservation soil,and conservation fertility and incresing effect of terraced farmland construction on the arid hillside land, the results showed that soil?water and fertility can be conserved; turn surface water into underground water; conservation of both moisture and soil , improved the grain yield.
