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

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.

Abstract: A method for preparing organic multi-micro-fertilizer with water retention function is provided, including: effectively remixing substance containing organic multiple trace elements, attapulgite powder, sodium p-toluenesulfonate, vermiculite and perlite under certain conditions. The present invention has obvious effects on enhancing soil water-holding performance, preventing physiological diseases of crops caused by lack of trace elements, and promoting growth and development of the crops.

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

Abstract: The present invention provides a special fertilizer for cut side slope soil remediation in high altitude areas, which is prepared by effectively compounding raw material components of a yak manure-containing compost, an organic micro multi-element fertilizer, a chemical fertilizer, attapulgite powder and sodium alginate under certain conditions. The special fertilizer has obvious effects on the aspects of improving the physicochemical properties of artificial soil at cut side slope wounds in the high altitude areas, increasing the fertilizer efficiency and promoting vegetation restoration.
