Abstract
A method for preparing an organic manganese fertilizer for engineering wound soil remediation includes a step of: effectively compounding chitin oligosaccharide or/and wormcast or/and silkworm excrement, water or/and hydrogen peroxide, an organic manganese element solution, polysorbate and sodium carboxymethyl cellulose under certain conditions. The present invention has significant effects on improving physical and chemical properties of engineering wound soil, enhancing availability of manganese element in the soil, preventing plants from physiological diseases caused by lack of manganese, and promoting growth and development of the plants.
