- Abstract:
- Soil erosion is the main restricting factor on agricultural development in northern arid area of China. The study on soil and water conservation of conservation tillage measures has an important guidance to the northern arid areas. In this study, soil water storage, water balance and water use efficiency of different conservational tillage measures were examined through field experiment, and then the effects of water and soil conservation of different tillage measures were evaluated comprehensively. The results showed that the water storage of cross slope tillage, cross slope cultivation, deep loosing+ridge tillage, ridge tillage, deep loosing tillage and no-till tillage was equivalent to 112.6%, 110.8%, 107.0%, 104.9%, 103.8% and 102.5% of conventional tillage respectively. Cross-slope tillage and ridge tillage could reduce runoff and soil erosion efficiently on the slope, play an important role in soil and water conservation, provide favorable soil moisture environment for crop growth.
