Agent for rapidly repairing vegetation in plateau environment and modifying sandy soil matrix

Abstract

The invention relates to a plateau environment vegetation rapid restoration and desertification soil matrix modifier, which is prepared by mixing the following materials in parts by weight: 4 to 6 parts of hydroxymethyl cellulose, 60 to 100 parts of organic fertilizer, 20 to 40 parts of activated sludge and 10 to 30 parts of charcoal powder. The invention relates to an environment-friendly building material, which is prepared from the following raw materials in parts by weight: 5 to 20 parts of bentonite or diatomite or industrial flour or siliceous fossil powder or coal gangue powder or coal ash, 5 to 20 parts of stone powder or zeolite powder or montmorillonite powder or kaolin, 20 to 40 parts of plant fiber, 1 to 5 parts of wood vinegar or bamboo vinegar, 0.1 to 0.5 part of cationic polyacrylamide and 0.01 to 0.05 part of plant polysaccharide. The invention aims to provide the amendment for rapidly repairing the vegetation in the plateau environment and the desertification soil matrix, which can be used for greening the water-deficient plateau environment and the high-altitude and large-angle slope land with the height of 4500 meters or above, and meanwhile, can well promote the growth of plants and enable the survival rate of the plants in the next year to be high.

Description

technical field [0001] The present invention relates to a highland environment vegetation rapid restoration and sandy soil matrix modifier. Background technique [0002] Common re-greening techniques in the prior art include soil-covering planting, hanging net spraying, ecological bag re-greening, step (slope rate) re-greening technology, etc. However, these several methods of re-greening have certain limitations. When the slope is greater than 45 degrees, it is difficult to construct, and when the slope is large, the construction investment cost is high, and the rock mass needs to be reinforced by other auxiliary means before construction. The cost of re-greening the ecological bag is high, and the later maintenance cost is large. In the plateau environment with high altitude and water shortage, the time suitable for plant growth is short, and the regreening project needs to shorten the germination time as much as possible to promote plant growth to ensure the survival rat...
