Application of moderate alkaline soil modifier

Abstract

The invention relates to an application of a moderate alkaline soil modifier to soil improvement. The moderate alkaline soil modifier comprises, by weight, 80 to 90 parts of desulfation wastes, 3 to 5 parts of inorganic accelerators and 8 to 15 parts of organic accelerators. According to the moderate alkaline soil modifier, calcium ions in the desulfation wastes are utilized to replace exchangeable sodium on soil colloid, so that the alkalinity of the soil is reduced; simultaneously excellent pore structures and physical properties of the organic accelerators are utilized, so that the physical properties and the granular structure of the soil can be improved, the potential of hydrogen (pH) value of the soil can be reduced, and the soil fertility is increased; the granular structure of the soil can be improved as well by the aid of the inorganic accelerators; and the soil fertility can be further improved by the aid of inorganic fertilizers and organic fertilizers, and nutritional ingredients can be provided for crop growth. In a word, the moderate alkaline soil modifier has the advantages that the unbalanced nutrition elements in the soil can be effectively avoided, the soil fertility can be improved, the soil can be loosened, the fertilizer efficiency is increased, and the soil salinization and alkalization can be gradually and radically treated.

Description

technical field [0001] The invention relates to a chemical reagent used on soil, in particular to a moderately alkalized soil improver and its processing method, and the application of the moderately alkalized soil improver, belonging to the field of soil improvement. Background technique [0002] Domestic soil improvement, especially the methods and technologies of saline-alkali land improvement can be summarized as follows: (1) Physical improvement: leveling the land, deep plowing and sunning, loosening the soil in time, raising the terrain, and micro-area improvement of the soil; (2) Water conservancy improvement: irrigation (3) Chemical improvement: application of gypsum, phosphogypsum, superphosphate, humic acid, peat, vinegar residue, etc.; (4) Biological improvement: planting rice , planting salt-tolerant plants, such as tianjing, or using micro-bacterial fertilizers, etc. [0003] These improved technologies and methods include ancient technologies, such as leveling...

AI Technical Summary

Problems solved by technology

If the particle size of the modifier after crushing is large, it is not conducive to the ion exchange reaction, and the improvement effect is poor; if the particle size of the modifier is small after crushing, it will consume a lot of energy, making the cost of soil improvement too high for farmers to bear

Chinese patent application CN101624523A discloses "a saline-alkali improver", which is prepared by mixing aluminum sulfate, ferrous ammonium sulfate and magnesium sulfate according to different weight ratios. A large amount of chemical raw materials are required to make the improver, instead of using Industrial waste, high cost

[0005] In general, the disadvantages and technical problems of the prior art are: complex process, high cost, and unsatisfactory effect
