摘要
在旱坡地上采取隔坡集蓄径流水平沟的整地方法营建枣园,集蓄坡面径流,增加枣园土壤含水率,有效地控制水土流失;通过对枣园土壤水分连续3年的定点观测,掌握了枣园土壤水分动态的变化规律。分析结果表明,所采取的集水工程集水效果较好。
Arid slopes are the typical site of jujube, Ziziphus jujuba .orchards in the loess hilly areas of Northern China. In our study we applied alternate contour trenches to soil preparation to catch the runoff flow on the slope. This practice enabled the soil moisture to increase by 32. 10 percent as compared with the check plot. Besides,soil erosion was effectively controlled thanks to this water collecting approach.
