Repair method of high and steep slope
The invention discloses a method for repairing a high and steep slope, which comprises the following steps of: performing step type slope cutting on the high and steep slope, forming an intercepting ditch on a step platform, and forming a water guide groove on a step slope surface; nutrient soil is laid on surface soil on the surface of the high and steep slope to form a planting layer; respectively sowing plant seeds on the bottom layer, the middle layer and the surface layer of the planting layer; according to the remediation method, multi-family plants such as shrub, herbaceous, woody, gramineae and rosaceae are combined with one another, and the competition of the plants for nitrogen, phosphorus, potassium, other trace elements, space, sunlight and water is slowed down through layered sowing and staggered plant growth nodes, so that intraspecific competition and interspecific competition of the plants are reduced, and the survival rate of the plants is remarkably increased; meanwhile, each plant emerges at different time, so that the influence of natural rainfall on the soil moisture content can be reduced, and the risk of collective large-area death of seedlings caused by short-time drought in the seedling stage is greatly reduced.
本发明公开了一种高陡边坡的修复方法，所述修复方法包括如下步骤：对高陡边坡进行台阶式削坡，在台阶平台上开设截水沟并在台阶坡面上设置引水槽；在高陡边坡表面的表层土上铺设营养土，形成种植层；在种植层的底层、中层和表层分别播种植物种子；本发明修复方法利用灌本、草本、木本、禾本科、蔷薇科等多科植物相互结合，并通过分层播种，错开植物生长节点，减缓植物对氮、磷、钾、其他微量元素以及空间、阳光、水分的竞争，进而减少植物种内竞争及种间竞争，显著提高了植物存活率；同时各植物不同时间出苗，能够降低自然降雨对墒情的影响，大大降低苗期因短时间干旱而造成的幼苗集体大面积死亡的风险。
