山区公路建设开山劈岭,形成了大量高陡、瘠薄裸露边坡,植被种子在坡面极难附着、出苗、成活、生长。利用水泥钢材灌注工程治理,成本高,山区不可能实现大面积完全治理。本试验示范通过优选出山区公路边坡适合生长的草灌复合种子组合,播前种子处理、浸种、粘合剂使用、带土带肥播种和播种后无纺布覆盖,使播种种子在坡面上能很好附着、出苗、存活、生长。并通过使用本地野生种子资源及采用人工播种等措施大大降低治理成本,实现了对山区高陡、贫瘠公路边坡的低成本、快速、高效的大面积治理。
The construction of mountain road slopes, forming a large number of steep, barren bare slopes, vegetation seeds extremely difficult to attach in the slope, emergence, survival and growth. The use of cement steel infusion project management, high cost, mountainous area can not be achieved in a full area of complete governance. The experiment demonstrated that the sowing seed can be planted on slope by optimizing the combination of grass and irrigated grass suitable for growing slope in the mountainous area, pre-sowing seed treatment, soaking seeds, using of adhesive, sowing with seeding fertilizer and non- On the very good attachment, emergence, survival, growth. Through the use of local wild seed resources and the use of artificial seeding and other measures to greatly reduce the cost of governance, to achieve high mountain steep, barren highway slopes low-cost, fast and efficient large-scale management.
