preparation example Construction

[0027] A preparation method of coastal saline-alkali soil improver, comprising the steps of:

[0028] S1. Weigh the straw, polyacrylamide, humus, wood vinegar, microbial agent and inorganic salt according to the mass ratio, mechanically crush the straw into debris and evenly mix with the humus;

[0029] S2, dilute the concentrated wood vinegar according to the ratio of 1:200, fully and uniformly mix and react with the straw and humus;

[0030] S3, dissolving polyacrylamide in water, and evenly spraying it on the above-mentioned mixed debris of straw and humus;

[0031] S4. Add microbial agent and inorganic salt, mix uniformly, granulate, and dry to obtain coastal saline-alkaline soil improver.

[0032] Its on-site preparation and application methods specifically include the following steps:

[0033] A. Take the straw, polyacrylamide, humus, wood vinegar, microbial agent and inorganic salt according to the size of the field and convert the mass ratio; break the straw and spre...

Abstract

The invention provides a coastal saline-alkali soil improver, which is prepared from the following ingredients in parts by mass: 20 to 40 parts of straw, 10 to 20 parts of polyacrylamide, 20 to 50 parts of humus, 2 to 5 parts of wood vinegar, 5 to 10 parts of a microbial agent and 5 to 10 parts of an inorganic salt, and the the wood vinegar is concentrated again after plant distillation and pyrolysis; and the microbial agent is prepared from bacillus megatherium, bacillus subtilis, pseudomonas, saccharomycetes and brevibacterium halotolerans. The natural humic acid matrix and the wood vinegar are mixed, humic acid nutrients in the humic acid matrix are primarily activated, then the humic acid matrix is slowly decomposed for a long time through the compound microbial agent, humic acid is slowly released, and the problem that the sandy soil of the coastal saline-alkali land does not retain fertilizer is effectively solved.

Description

technical field [0001] The invention relates to a coastal saline-alkali soil improver and a preparation method thereof. Background technique [0002] At present, soil salinization has become a global resource and environmental problem. my country's existing saline-alkali land area is about 99 million hectares, including 5 million hectares of coastal saline-alkali land. With the implementation of the eastern coastal development strategy, the area of ​​newly reclaimed tidal flats is still growing. It is known as the most valuable reserve land in the central and eastern regions of my country. resource. In coastal saline-alkali land, due to the influence of the source of soil-forming parent material and the soil-forming process, the salt content in the soil is relatively high. Generally, the salt content of newly reclamated coastal saline-alkali land is between ten and thirty thousandths; the soil is solid and structural. And the permeability is poor, the soil nutrient content ...
