Biological soil restoration fertilizer

Abstract

The invention discloses a biological soil restoration fertilizer. The fertilizer is prepared from, by weight, 32-36 parts of biogas slurry, 4-5 parts of saccharomyces cerevisiae, 6-9 parts o brown sugar, 3-4 parts of calcium powder, 1-2 parts of copper sulphate pentahydrate, 26-30 parts of flax fiber bundles, 15-17 parts of siderite slag, 15-17 parts of limonite slag, 68-70 parts of orange peels, 3-6 parts of an EM compound microbial agent and a defined amount of water. By means of the biological soil restoration fertilizer, biological activity of soil can be effectively improved, growth and expanding of plant roots are facilitated, water permeability and air permeability of the soil are improved, the soil is prevented from being eroded by bacteria and pests, healthy growth of plants is promoted, meanwhile, heavy metal can be subjected to a precipitation reaction, a chelation reaction and other reactions in the soil, bio-availability of the heavy metal is lowered, the absorbing capacity of the crops for the heavy metal is reduced, quality of agricultural products is improved, and the ecological environment of the soil is restored.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a biological soil restoration 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 metho...

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.
