摘要
砒砂岩区水土流失十分严重,不仅产沙量大,而且粗沙比例高,对黄河危害极大。通过多年的探索,总结出沙棘治理砒砂岩的布局:沟坡布设沙棘护坡林、沟道坡脚布设沙棘挡沙坝、沟底布设沙棘拦沙坝。沟底拦沙坝布局根据沟道洪水大小确定。同时在砒砂岩沟道使用沙棘种植专用工具,提高沙棘种植工效3~5倍,同时提高了沙棘种植的质量,在寸草不生的砒砂岩上,沙棘种植成活率可达90%以上。
Soil erosion in soft rock area is very serious, it not only producing large amount of sand, but also got a high percentage of rough sand. This is extremely harmful to Yellow River. Based on many years study, we find out a layout of governance soft rock by seabuckthorn. At the same time, by special sea buckthorn planting tool in soft rock channel can improve the plant efficiency for 3 to 5 times therefore improve the planting quality. Seabuckthorn survival rate can reach over 90%.
