Long-acting carbon-reducing soil restoration fertilizer

Abstract

The invention discloses a long-acting carbon-reducing soil restoration fertilizer which is prepared from, by weight, 12-15 parts of tobacco powder, 6-7 parts of pine pollen, 38-40 parts of plant ash, 6-7 parts of boronic acid, 1-2 parts of sodium sulphide, 1-2 parts of sodium bismuthate, 26-28 parts of deal, 14-16 parts of siderite slag, 14-16 parts of limonite slag, 74-76 parts of orange peel, 4-5 parts of an EM composite microbial agent and a proper amount of water. According to the long-acting carbon-reducing soil restoration fertilizer, a structure of biochar solid-supported organic matter is adopted, the fertilizer has good corrosion resistance and can form aggregate together with mineral substances in soil, the function of microorganisms on biochar is weakened, and the fertilizer can stay in the soil for a long time. The surface adsorbs dissolvable organic carbon to promote formation of soil particles wrapped by organic matter, the mineralization function of the organic carbon of the soil is reduced, emissions of CO2 are reduced, and the aims of soil restoration, carbon sequestration and emission reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a long-acting carbon-reducing 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 hea...

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.
