Abstract

The invention discloses a preparation method of desulfurized gypsum capable of being used for loosening paddy soil. The desulfurized gypsum is concretely prepared from the following ingredients in parts by weight: 500 to 800 parts of desulfurized gypsum powder, 50 to 80 parts of plant ash, 30 to 50 parts of wood shavings, 30 to 50 parts of fine sand, 15 to 20 parts of amino acid, 25 to 35 parts of phosphoric acid and 15 to 30 parts of azotobacters. Compared with conventional desulfurized gypsum, the desulfurized gypsum prepared by the preparation method of the desulfurized gypsum capable of being used for loosening paddy soil provided by the invention has the advantages that the plant ash, the wood shavings, the fine sand, the amino acid and the desulfurized gypsum powder are sufficiently and uniformly mixed and are then made into particles; the effects of the desulfurized gypsum in the paddy field is enhanced; meanwhile, phosphorous acid is used for neutralizing the alkalescence of the plant ash; in addition, the azotobacters are added so as to reduce the influence of the plant ash on the survival quantity of the paddy field azotobacters; the survival of the azotobacters is effectively maintained.

Description

technical field [0001] The invention belongs to the technical field of planting, and more specifically relates to a method for preparing desulfurized gypsum capable of loosening paddy field soil. Background technique [0002] The main component of desulfurization gypsum is the same as natural gypsum, which is calcium sulfate dihydrate crystal in powder form. However, desulfurized gypsum has a high water content, is slightly soluble in water, and has strong viscosity. It is necessary to add soil loosening agent when desulfurized gypsum is used for improving paddy fields, but the effect is not obvious. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a method for preparing desulfurized gypsum that can loosen paddy field soil. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A method for preparing desulfurized gypsum capable of lo...
