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 CN101624523 discloses "a kind of saline-alkali improver", which is prepared by mixing aluminum sulfate, ferrous ammonium sulfate and magnesium sulfate according to different weight ratios. It needs a large amount of chemical raw materials to make the improver, instead of using Industrial waste, high cost
Chinese patent CN1664064A discloses "an alkaline soil improver" which mainly uses phosphogypsum, straw and urea in different proportions to make a soil improver; High element content will cause heavy metals and harmful trace elements in the improved soil to exceed the allowable value of the national standard
[0005] In general, the disadvantages and technical problems of the prior art are: complex process, high cost, and unsatisfactory effect

Abstract

The invention relates to a conditioner for severely alkaline soil and a processing method of the conditioner. The conditioner for the severely alkaline soil comprises the following raw materials in parts by weight: 88-92 parts of desulfuration waste, 1-3 parts of inorganic accelerator and 5-11 parts of organic accelerator. According to the conditioner for the severely alkaline soil, calcium ions in the desulfuration waste are used for replacing exchangeable sodium on a soil colloid, so that the alkalisation degree of the soil is reduced; an excellent pore structure and physical properties of the organic accelerator are used for improving physical characteristics and a granular structure of the soil; the pH value of the soil is decreased; the soil fertility is increased; the inorganic accelerator also can improve the granular structure of the soil; an inorganic fertilizer and an organic fertilizer are additionally adopted to further increase the soil fertility; and nutritional ingredients are provided for crop growth. In a word, the conditioner can effectively overcome nutritional element unbalance in the soil, increase the soil fertility, loosen the soil, improve the fertilizer efficiency and fundamentality control soil salinization gradually.

Description

technical field [0001] The invention relates to a chemical reagent used on soil, in particular to a heavily alkalized soil improver and a processing method thereof, 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 the land, deep plowing and drying, loosening the soil in ti...
