Acidified soil restoration fertilizer

Abstract

The invention discloses acidified soil restoration fertilizer. The acidified soil restoration fertilizer is prepared from, by weight, 18-20 parts of dead leaves, 29-31 parts of potato straw powder, 6-7 parts of loofah powder, 1-2 parts of calcium cyanamide, 3-4 parts of sodium polyphosphate, 5-6 parts of dolomite powder, 28-30 parts of red gum bark, 19-21 parts of siderite slags, 19-21 parts of limonite slags, 65-70 parts of orange peels, 3-4 parts of EM compound microorganism bacterium agent and an adequate amount of water. According to the acidified soil restoration fertilizer, the soil acidification condition can be improved, the soil fertility disorders derived from soil acidification is relieved, a soil-borne disease caused by soil acidification is controlled, calcium ions in the soil are supplemented by adding the calcium cyanamide and the dolomite powder, a calcium ion leaching phenomenon caused by the soil acidification is relieved, various microelements are supplemented adequately, and restoration of acidified soil is achieved economically and effectively.

Description

Technical field [0001] The invention relates to the technical field of fertilizers, in particular to an acidified soil restoration fertilizer. Background technique [0002] With the rapid economic development and the advancement of industrial technology, the adverse effects of industrial and agricultural production on the environment are increasing. As solid wastes are continuously stacked and dumped on the soil surface, hazardous waste water continues to penetrate into the soil, and harmful gases and dust in the atmosphere It also continued to fall into the soil with rain, causing soil pollution. Not only reduces the yield and quality of crops, but also indirectly harms human health. [0003] The control of soil pollution is mainly through engineering remediation methods and phytoremediation methods. The engineering remediation methods mainly include soil modification, electric remediation, soil leaching and heat treatment. Engineering treatment measures are usually applied to sm...

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.
