Soil remediation fertilizer for newly-exploited farmland of mining area

Abstract

The invention discloses a soil remediation fertilizer for newly-exploited farmland of a mining area. The soil remediation fertilizer is prepared from, by weight parts, 44-48 parts of bagasse, 9-11 parts of fish bone meal, 6-7 parts of river sand, 2-4 parts of calcium chloride, 1-2 parts of aluminum potassium sulfate, 1-3 parts of magnesium oxide, 50-55 parts of bombax ceiba shell, 16-18 parts of siderite residue, 16-18 parts of limonite residue, 37-41 parts of orange peel, 5-6 parts of EM compound microorganism bacterium agent and an appropriate amount of water. According to the soil remediation fertilizer, according to the characteristics of high heavy metal and dust content in the newly-exploited farmland of the mining area, pollution adsorption is performed through highly active magnetic charcoal; the content of organic humus ingredients in the soil is greatly improved after the fish bone meal is become thoroughly decomposed, a physicochemical state of the farmland soil is improved, the soil fertility is improved quickly, and the productivity of the newly-exploited farmland is improved.

Description

Technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer for soil restoration of newly cultivated farmland in mining areas. Background technique [0002] With the rapid economic development and the advancement of industrial technology, the adverse effects of industrial and agricultural production on the environment are increasing. As solid wastes are continuously stacked and dumped on the soil surface, hazardous waste water continues to penetrate into the soil, and harmful gases and dust in the atmosphere It also continued to fall into the soil with rain, causing soil pollution. Not only reduces the yield and quality of crops, but also indirectly harms human health. [0003] The control of soil pollution is mainly through engineering remediation methods and phytoremediation methods. The engineering remediation methods mainly include soil modification, electric remediation, soil leaching and heat treatment. Engineering treatm...

Not only reduces the yield and quality of crops, but also indirectly endangers human health

[0003] The control of soil pollution is mainly through engineering restoration methods and phytoremediation methods, of which engineering restoration methods mainly include soil improvement methods, electric restoration, soil leaching and heat treatment methods, etc. Engineering treatment measures are usually suitable for small polluted areas and serious pollutants. And the effect of the soil that is easy to spread is more obvious, which can fundamentally improve the soil, but the cost of treatment is high, and it is easy to form secondary pollution, and may damage the soil structure, which may easily lead to a decline in soil fertility

Phytoremediation technology is usually low-cost and can improve soil organic matter content and soil fertility, but plants have limited tolerance to heavy metal pollutants and are only suitable for moderately polluted soil remediation. At the same time, a plant can usually only remediate a certain heavy metal pollution Soil, and it is possible to activate other heavy metals in the soil. It is not effective for the compound pollution of various metals and organic substances. Hyperaccumulators grow slowly, and the restoration period is usually long, which is difficult to meet the requirements of rapid restoration of soil pollution.
