Method of recovering and reconstructing vegetation of mining land

Abstract

The invention relates to a method of recovering and reconstructing vegetation of mining land, which comprises the following steps: clearing float stones and flattening broken stones; laying reticular fiber ecological mats along the slope; and punching holes on the laid ecological mats, mixing and uniformly stirring grass seeds, shrub seeds and loam soil, sowing the mixture into the holes, and then covering the holes by sun-shading nets. The invention can protect water and soil, i.e. prevent soil which is artificially covered on the slope of the broken stones from losing by covering the reticular fiber ecological mats, balance temperature, improve efficiency and prevent sand and dust from blowing.

Description

Technical field: [0001] The invention belongs to a technique for restoring and rebuilding vegetation, in particular to a method for restoring and rebuilding vegetation in mining ruins. Background technique: [0002] Due to the accelerated pace of urban construction, business opportunities have been created for the mining industry, resulting in disorderly and excessive mining of sand and stone mines, resulting in large-scale mountain damage, vegetation destruction, soil erosion, sand and dust, and other ecological and environmental problems. [0003] According to the actual conditions of the gravel flow slope of the mining site, artificial dam abutments, blasting and excavation, and foreign soil planting were adopted; large container seedlings, Pt mycorrhizal fungi, ABT rooting powder, SAP water-retaining agent, and plastic film were used to preserve moisture; drought-resistant Plant materials, trees (colour-leaf coniferous trees), shrubs, grasses, climbing vines and other en...

Problems solved by technology

[0010] Problems and deficiencies: After 5 years of continuous treatment, the tree has survived, the gravel slope of the mining site has been initially contained, and the landscape effect has been improved to a certain extent

However, because the mountains are full of rocks and no soil, and the spaces between the trees are full of gravel, the temperature is as high as 60-70°C under the sun at noon, and the saplings planted alive are like growing in flower pots and lack nutrients and water. It is difficult to maintain life in dry weather, and there is basically no growth

If the environmental conditions for tree growth are not fundamentally improved as soon as possible, even if the trees increase the maintenance cost, it will inevitably cause some trees to dry up and die
