摘要
为探索云南数百万亩坡耕地的科学利用措施,在云南宣威15°坡耕地上设置试验小区,连续两年系统研究了9m、13m、17m三水平草带间距与水土保持和土壤理化性状的关系。结果表明,在坡耕地上种植草带能有效防止水土流失,草带间距越小越有利于水土保持,但从控制水土流失和有利种粮耕作两方面综合考虑,草带间距以13m为宜。
The scheme of the research was conducted over the impact of different intervals between pasture belts on water and soil conservation as well as on physical and chemical characteristic of soil on the sloping arable land with the elevation of 150. The results indicated that water and soil erosion could be effectively controlled by planting pasture in belts on the sloping land. The shorter the interval between pasture belt was, the better results it would be in terms of erosion control. However, if considered the balance of soil erosion control and crops cultivation for proper land utilization, it was suggested that the interval between pasture belts should be 13 meters.
