Embodiment Construction

[0025] The invention discloses a method for improving the soil in a rare earth mining area, which comprises the following steps: S1100): improving the surface soil of the mining area, so that the surface of the mining area is suitable for growing grass; Pond, first filled with mixed soil, then filled with raw red soil on the mixed soil, and planted Camellia oleifera on the red soil; S1300): deep plowing is carried out from November to the end of April of the next year, and the grown grass is turned over to form humus, and spread grass seeds on the ground where white camellia oleifera is not planted on the ground to re-grow grass buds on the ground; S1400): repeat overturning and growing grass cover for 3-5 years, until a 0.3-meter-thick soil is formed on the ground in the mining area layer.

[0026] In this method, the surface soil of the mining area is firstly improved for the purpose of growing grass cover normally on the surface. The surface of the mining area is weathered ...

Abstract

A rare earth mining area soil improving method comprises the following steps that S1100, mining area ground surface soil improving is carried out, so that the mining area ground surface is suitable for sod growth; S1200, uniform pond punching is carried out according to the 3m*3m distance, composite soil filling is firstly carried out, the composite soil is filled with raw red soil, and white flower tea-oil trees are planted on the red soil; S1300, deep harrowing is carried out from November every year to the end of April of the next year, growing grass is turned and pressed, humus is formed, grass seeds are sown on the ground where the white flower tea-oil trees are not planted, and grass shoots grow out again on the ground surface; S1400, repeated turning and pressing and growing of sod are carried out for 3-5 years till a soil layer with the thickness of 0.3 m is formed on the mining area ground. Compared with other methods, the rare earth mining area soil improving method has the advantages of being low in cost and good in soil improving effect.

Description

technical field [0001] The invention relates to the field of soil improvement, in particular to a soil improvement method in a rare earth mining area. Background technique [0002] The mining of rare earths has aggravated the deterioration of the ecological environment in mining areas, and the ecological environment of abandoned lands formed by long-term mining of rare earths is not conducive to vegetation restoration. Therefore, how to restore the vegetation of the abandoned land of rare earth mining has become a major issue that needs to be solved urgently by the environmental science community. The management measures of abandoned mine land mainly include engineering measures and plant measures. Engineering measures can solve the problem of geological disasters within a certain range, but there are disadvantages such as high cost and secondary pollution in the treatment process. Plant measures can make up for the shortcomings of engineering measures. It has the advanta...
