Moisturizing and soil moisture preserving soil remediation fertilizer

Abstract

The invention discloses moisturizing and soil moisture preserving soil remediation fertilizer. The fertilizer is prepared from, by weight, 35-36 parts of rice straw, 6-8 parts of flammulina velutipes dregs, 10-12 parts of intestine and feather meal, 8-10 parts of bentonite, 4-5 parts of ammonium dihydrogen phosphate, 2-3 parts of sodium hydrogen sulfite, 39-41 parts of sugar beet pulp, 14-18 parts of siderite slag, 14-18 parts of limonite slag, 52-55 parts of orange peels, 3-6 parts of EM compound microbial agents and an appropriate amount of water. The organic waste residues are used as main raw materials of the soil remediation fertilizer and are reasonably matched with the bentonite, the microbial agents and the like, and physical and chemical properties of soil are improved; the organic filler of the appropriate percentage can increase the dialysis speed and the total porosity of the soil, increase the content of related saline ions, and improve the microbial activity and is beneficial to nutrient conversion and circulation and moisturizing and soil moisture preservation of the soil, and a good environment is provided for crop growth after remediation.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a moisture-retaining soil repair fertilizer. 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 heat treatment me...

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.
