Method for preparing organic boron fertilizer for engineering wound soil remediation and prepared organic boron fertilizer
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.
1. A method for preparing an organic boron fertilizer for engineering wound soil remediation, comprising steps of:
(1) adding at least one member selected from a group consisting of chitin oligosaccharide, wormcast and silkworm excrement, with a weight percentage of 30%-70%, into a first reaction kettle; then adding at least one member selected from a group consisting of water and hydrogen peroxide, with a weight percentage of 30%-70%, into the first reaction kettle for dissolution; stirring at 30-90° C. for 0.3-2 hours, and obtaining a first sample;
(2) adding at least one member selected from a group consisting of sodium alginate, triethanolamine and glycerol, with a weight percentage of 15%-40%, into a second reaction kettle; dissolving by water with a weight percentage of 15%-40%; then adding at least one member selected from a group consisting of hydrogen peroxide, sodium chlorate and ethanolamine, with a weight percentage of 1%-15%, into the second reaction kettle for dissolution; stirring at 30-90° C. for 0.2-3 hours; adding at least one member selected from a group consisting of boric acid and borax, with a weight percentage of 30%-65% into the second reaction kettle; boiling at 80-130° C. for 0.5-6 hours, and obtaining a second sample; and
(3) compounding the first sample, the second sample, sodium alkyl benzene sulfonate and polysorbate respectively with weight percentages of 5%-20%, 70%-90%, 0-6% and 0-6%, and obtaining the organic boron fertilizer.
