Abstract

The invention discloses artificial soil suitable for slope vegetation restoration of high-altitude areas and a preparation method thereof. The artificial soil comprises, by weight, 20-30 parts of calcium based bentonite, 10-15 parts of diatomite, 10-15 parts of citric acid, 10-20 parts of ceramic powder, 5-8 parts of potassium dihydrogen phosphate, 15-30 parts of peat soil, 10-15 parts of sodium humate, 5-10 parts of zinc oxide, 10-15 parts of bamboo fiber, 5-8 parts of compound fertilizer, 5-10 parts of polyacrylamide, 5-15 parts of super absorbent resin and 15-30 parts of microbial residue.The artificial soil prepared by the method has excellent buffering ability to temperature change and can enhance plant survival rate.

Description

technical field [0001] The invention belongs to the technical field of slope vegetation restoration, and in particular relates to an artificial soil suitable for slope vegetation restoration in high-altitude areas and a preparation method thereof. Background technique [0002] The rock slope has steep slope, hard surface, no soil, no vegetation, impermeable, no water storage, and the site conditions are very bad. The emergence of rocky slopes will not only aggravate soil erosion and damage the natural landscape, but also cause adverse effects on the regional ecological environment. In nature, the survival of most higher plants is inseparable from the soil. For the vegetation restoration of exposed rocky slopes, it is not only necessary to build and stabilize the guest soil layer on the surface of the rocky slope, but also to establish suitable Plant communities that survive on rocky slopes. In view of the limitation of factors such as slope slope and construction cost, and...
