Problems solved by technology

However, due to the lack of specific organic zinc fertilizers with good application effects, commercially purchased zinc fertilizers for farmland soil are still used in the process of engineering wound soil remediation, resulting in unreasonable fertilizer use, uncoordinated nutrient supply, A series of production problems such as low fertilizer utilization rate lead to inconspicuous effects of soil fertilization and vegetation restoration on engineering wounds

Embodiment 1

[0010] Put the chitosan oligosaccharide with a component weight percentage of 50% into a reaction kettle, add water with a component weight percentage of 50% to dissolve, and stir at 90°C for 0.3 hours to prepare a chitosan oligosaccharide solution for use. Put glycine with a component weight percentage of 25% into the reactor, dissolve it with water with a component weight percentage of 30%, then add hydrogen peroxide with a component weight percentage of 5% to dissolve, and stir at 90°C for 0.2 Hours; then, add zinc sulfate with a component weight percentage of 40% into the reaction kettle, boil it at 100°C for 0.5 hour, and prepare an organic zinc element solution for future use. The final product is obtained by compounding the chitosan oligosaccharide solution, 90% organic zinc element solution, 2% polysorbate and 3% carboxymethyl cellulose sodium in component weight percent respectively.

Embodiment 2

[0012] The operating procedure was the same as in Example 1 during preparation. Just change the type, quantity, dissolution temperature, stirring time and boiling time of raw materials within the scope specified by the operating procedures of the present invention, and still prepare a special organic zinc fertilizer for engineering wound soil repair of the present invention.

Abstract

The invention provides a preparation method of organic zinc fertilizer special for engineering wound surface soil remediation. The organic zinc fertilizer special for engineering wound surface soil remediation is prepared by effectively compounding raw material components of chitin oligose or / and wormcast or / and silkworm excrement, water or / and hydrogen peroxide, a solution containing organic zinc, polysorbate and sodium carboxymethylcellulose under certain conditions. The organic zinc fertilizer special for engineering wound surface soil remediation has significant effects in aspects of improving engineering wound surface soil physical and chemical characteristics, enhancing effectiveness of zinc element in soil, controlling physiological diseases caused by zinc deficiency of plants and promoting growth and development of the plants.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a method for preparing an organic zinc fertilizer specially used for engineering wound soil restoration. Background technique [0002] In the construction of railways, highways, mines, water conservancy, electric power and other projects, it is often necessary to excavate slopes and damage the ground surface, forming a huge number of engineering wounds. The formation of engineering wounds has severely damaged the original soil vegetation cover, resulting in a large number of secondary bare land, resulting in the continuous deterioration of the regional ecological environment. This not only reduces the regional environmental quality, but also poses a threat to the sustainable development of social economy. For engineering wounds with very special habitats, the soil remediation measures of stacking soil on engineering wounds in a specific way and revegetating are effective ways for modern engineeri...
