山丘区的水土保持,是水利发展战略的一项重要内容,丘陵区的坡改梯,是节水、改土增产的一项重要战略措施。坡耕地改成水平梯田,能够保水、保土、保肥,亩产可望翻番。本文通过对淮北丘陵区的增产潜力、低产根源的分析,阐述了坡改梯和节水、改土增产的关系,探讨了坡改梯节水、改土增产的措施,对淮北地区坡改梯增产效益进行了预测。
Soil and water conservation in the hills and valleys is an important part of the water conservancy development strategy. The slope-climbing and grazing in the hilly areas is an important strategic measure for saving water and improving soil yield. Sloping farmland into a horizontal terrace, able to water, soil, fertilizer, is expected to double per mu. Based on the analysis of potential yield increase and low yield root cause in hilly area of Huaibei, the paper expounds the relationship between slope improvement and water saving and soil improvement and yield increase. The measures of slope water improvement and soil improvement are discussed. Prediction of yield increase.
