Abstract
A method for preparing an organic complex microelement fertilizer for engineering wound soil remediation includes compounding chitosan oligosaccharide or/and earthworm dung or/and silkworm sand, water or/and hydrogen peroxide, an organic complex trace element solution, polyethylene glycol octyl phenyl ether, and polysorbate under certain conditions. The present invention can significantly improve physical and chemical properties of engineering wounds, enhance effectiveness of trace elements in soil, and prevent plant physiological diseases due to lack of trace elements, and promote plant growth and development.
