Fertilizer for repairing soil contaminated by snow-melting agents

Abstract

The invention discloses fertilizer for repairing soil contaminated by snow-melting agents. The fertilizer is prepared from, by weight, 30-34 parts of mushroom bran, 8-12 parts of seaweed meal, 14-16 parts of cattle bone powder, 10-12 parts of bean pulp, 6-7 parts of sepiolite powder, 3-4 parts of pyroligneous liquor, 2-3 parts of copper sulfate, 36-38 cow dung, 16-18 parts of siderite slag, 16-18 parts of limonite slag, 60-65 parts of orange peel, 4-6 parts of EM compound microorganism bacterium agents and a proper amount of water. According to the fertilizer for repairing soil, for soil hardening and salinization caused by inorganic snowmelt agents which are current used, the breathability and water binding capacity of soil are improved through adding of organic materials, salt in the snow-melting agents is adsorbed and neutralized in match with the sepiolite powder, the pyroligneous liquor and the like, contamination of underground water is eliminated, meanwhile composition of soluble salt is adjusted, the fertility of the contaminated soil is enhanced, and the fertilizer has important practical value on the aspect of soil repair of green belts along highways.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer for repairing snow-melting agent polluted soil. Background technique [0002] With the rapid development of the economy and the advancement of industrial technology, the adverse impacts of industrial and agricultural production on the environment have been increasing. Due to the continuous accumulation and dumping of solid waste on the soil surface, harmful waste water has continuously penetrated into the soil, harmful gases and dust in the atmosphere It also continues to fall into the soil with rainwater, causing soil pollution. It 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 h...

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.
