Problems solved by technology

[0002] After the closure of most acid mines in the south, soil fertility decreased, soil erosion was serious, soil degradation and desertification intensified, soil ecological environment deteriorated, and soil ecological functions declined. Deficiency. According to the soil survey, the organic matter content and the nutrient elements necessary for plants are seriously lacking, which is not conducive to the recovery and growth of plants. Therefore, effective measures must be taken to improve the nutritional status of the soil.
[0003] At present, there are many types of mine soil remediation substrates, but all of them can only solidify heavy metals in the soil or improve the soil temporarily, and cannot achieve the purpose of long-term improvement of mine soil

Embodiment 1

[0019] An acidic mine restoration matrix improver, comprising the following components by weight: 45kg of red mud, 30kg of organic fertilizer, 3kg of plant ash, 1kg of high molecular weight polyacrylamide, 0.2kg of compound microbial bacteria, 3kg of sepiolite, 1kg of EDTA , limestone 3kg and potassium dihydrogen phosphate 0.2kg.

[0020] Preferably, the organic fertilizer includes chicken manure, mushroom dregs, straw and wheat straw, and the chicken manure, mushroom dregs, rice straw and wheat straw are mixed in a weight ratio of 5:2:2:1. Mushroom slag is the waste left over from the production of mushrooms. The main components are plant materials such as crop straws, which contain a large amount of crude protein and cellulose. After fermentation, most of the crude protein and fiber are completely decomposed.

Abstract

The invention discloses an acid mine repair matrix improver and a preparation method thereof. The acid mine repair matrix improver is prepared from the following components in parts by weight: 45-50 parts of red mud, 30-35 parts of an organic fertilizer, 3-5 parts of plant ash, 1-2 parts of high polymer polyacrylamide, 0.2-0.5 part of composite microbial flora, 3-5 parts of sepiolite, 1-2 parts ofEDTA, 3-5 parts of limestone and 0.2-0.5 part of monopotassium phosphate. Various nutrients in soil can be effectively increased by adopting the acid mine repair matrix improver, the character of thesoil matrix is enhanced for a long time, and thus a good external environment is provided for plant growth and recovery.

Description

technical field [0001] The invention relates to the technical field of mine restoration matrix, in particular to an acidic mine restoration matrix modifier and a preparation method. Background technique [0002] After the closure of most acid mines in the south, soil fertility decreased, soil erosion was serious, soil degradation and desertification intensified, soil ecological environment deteriorated, and soil ecological functions declined. Deficiency, from the soil survey, the organic matter content and the essential nutrients of plants are seriously lacking, which is not conducive to the recovery and growth of plants. Therefore, effective measures must be taken to improve the nutritional status of the soil. [0003] At present, there are many types of mine soil remediation substrates, but all of them can only solidify heavy metals in the soil or improve the soil temporarily, and cannot achieve the purpose of long-term improvement of mine soil. Contents of the invention...
