Problems solved by technology

However, due to the lack of targeted and effective special organic copper fertilizers, copper fertilizers purchased on the market 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, stir at 80°C for 0.5 hours, and prepare a chitosan oligosaccharide solution for use. Put tartaric acid with a component weight percentage of 25% into the reactor, dissolve it with water with a component weight percentage of 30%, then add ethanol with a component weight percentage of 5% to dissolve, and stir at 80°C for 0.5 hours; Then, copper sulfate with a component weight percentage of 40% was added into the reaction kettle, and boiled at 100° C. for 1 hour to prepare an organic copper element solution for future use. The final product is obtained by compounding 10% chitosan oligosaccharide solution, 80% organic copper element solution, 3% polyethylene glycol octyl phenyl ether, and 2% tea saponin by weight percentage. .

Embodiment 2

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

Abstract

The invention provides a preparation method of an organic copper fertilizer dedicated to engineering destroyed surface soil repairing. The fertilizer is prepared by effectively blending the raw materials including chitin oligose or / and earthworm cast or / and silkworm excrement, water or / and H2O2, a solution containing organic copper element, polyethylene glycol octylphenol ether, and tea saponin under a certain condition. The fertilizer has significant effect of modifying physical and chemical properties of the engineering destroyed surface soil, increasing availability of copper in soil, preventing and treating physiological disease caused by copper deficiency in plants, and promoting growth and development of plants.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a method for preparing an organic copper fertilizer specially used for engineering wound soil restoration. Background technique [0002] The rapid development of infrastructure construction such as roads, railways, and water conservancy has produced a large number of engineering wounds, which have changed the original topography and destroyed the original natural soil and vegetation. Engineering wounds not only affect the safety of infrastructure, but also lead to the deterioration of the natural environment, which requires timely ecological restoration. Soil remediation of engineered wounds is the basis for vegetation restoration of engineered wounds and the main task of ecological restoration of engineered wounds. 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 moder...
