Method of soil reclamation pellet for rice crop of saline soil using gypsum and organics sludge

摘要

The present invention is a seasoning plant for the waste gypsum (Gypsum, CaSO ₄ , 2H ₂ O) and other wastes produced in the process of manufacturing phosphate (P ₂ O ₅ ) fertilizer and paper waste pulp sludge and thermal power plant incinerator Fly-ash seasoning plant Fermentation compost of complex soil improver and organic waste containing gypsum and organic matter, silicic acid, active phosphoric acid, lime and zinc needed to improve reclaimed paddy soil by granulating and drying granules from food factories such as fermented wastewater (Amino acid) as an adhesive It provides granular composition used as a moisture control material (bulking agent, bulking agent) and its manufacturing method, and supplies rice to the reclaimed land at low cost, contributing to the production of grains (rice), conserving the environment and contributing to the sustainable economic development. It is an environmentally friendly useful invention.;International competitiveness is provided by providing a viable complex improvement system to the reclaimed paddy soil, which is being expanded by the government's reclamation project for the self-sufficiency of grain for rice in preparation for international food weaponization in the era of infinite competition under the WTO agreement and UR. It is a national invention that contributes to the development of self-sufficiency for rice production and rice production and government food policy.
