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...
