Abstract

The invention relates to a modifier for mildly alkalized soil and a processing method thereof. The modifier for mildly alkalized soil comprises the following raw materials in parts by weight: 70-80 parts of desulfurized waste, 5-10 parts of inorganic accelerator and 10-20 parts of organic accelerator. According to the modifier for mildly alkalized soil, exchangeable sodium on soil colloid is replaced by calcium ions in the desulfurized waste, thereby reducing the alkalization degree; because of the fine pore structure and physical property of the organic accelerator, the physical behavior of the soil and the crumb structure of the soil are improved, the pH value of the soil is reduced, and the fertility of the soil is increased; the inorganic accelerator can also improve the crumb structure of the soil; and an inorganic fertilizer and an organic fertilizer are added to further increase the fertility of the soil and provide nutrient contents for the growth of plants. In a word, the invention can effectively avoid the nutrient element unbalance in the soil, improve the productivity of the soil, loosen the soil, enhance the fertilizer efficiency and thoroughly control the soil salinization phenomenon step by step.

Description

technical field

[0001] The invention relates to a chemical reagent used on soil, in particular to a mild 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 roughly summarized as follows: (1) Physical improvement: leveling the land, deep plowing and sunning, loosening the soil in time, raising the terrain, and micro-area soil improvement; (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 time...
