preparation example Construction

[0024] A preparation method for treating soil salinization composite particles, the preparation method comprising the following steps:

[0025] (1) In terms of parts by weight, take 120-130 parts of water, 40-50 parts of slag, 32-36 parts of diatomaceous earth, 16-18 parts of polyglutamic acid, 12-16 parts of ammonium bicarbonate, 10- 13 parts of water-based polyurethane, 6-9 parts of additives and 3-5 parts of dispersant;

[0026] (2) Put water, slag, diatomaceous earth, ammonium bicarbonate and dispersant into the container, oscillate ultrasonically for 30 minutes, then add polyglutamic acid, water-based polyurethane and additives, and place at 35-45°C, stir 1 to 3 hours, freeze-dried, crushed at 500r / min for 15 minutes to obtain the carrier material, and set aside;

[0027] (3) In terms of parts by mass, take 78-82 parts of water, 40-45 parts of wheat straw, 23-26 parts of mixed manure, 18-24 parts of peat soil, 11-16 parts of sucrose, 6-8 parts of additives and 2-4 parts...

Abstract

The invention belongs to the technical field of soil remediation and specifically relates to a soil alkalization treating compound particle preparation method. According to the preparation method disclosed by the invention, coal ash, vermiculite, clam shell and steel slag are prepared into a slag material; the slag material and kieselguhr are mixed, so that the kieselguhr is modified, and soil humidity adjusting capacity of the kieselguhr is improved; meanwhile, ion exchange channel performance of the kieselguhr is improved; furthermore, the mixed particles can effectively separate out calciumions, so that an exchangeable sodium ion content in salinity soil is reduced, soil exchangeable sodium percentage is reduced, soil granular structure formation is promoted, and a soil bulk density isreduced. According to the preparation method disclosed by the invention, wheat straw, mixed excrement, peat soil and the like are mixed and fermented; nutrient substances and microorganisms are gathered through granular adsorbent load; as organic matter can generate varieties of organic acid in a soil decomposing process, negative ion solubility in the soil is improved; furthermore, microorganismeffects are utilized to further adjust the soil, and a treating effect is improved.

Description

technical field [0001] The invention belongs to the technical field of soil treatment, and in particular relates to a preparation method of composite particles for controlling soil salinization. Background technique [0002] Soil salinization is one of the types of soil degradation. It is a global problem. It not only causes the destruction of soil resources and soil degradation, but also directly affects crop yield. Today, with the increasing population and decreasing arable land, it seriously restricts the social economy. development and progress. [0003] At present, for the control of saline-alkali soil, chemical improvement is a relatively traditional and widely used measure. Chemical improvement is the application of some acidic salts to improve the properties of saline-alkali land, reduce the pH of the soil, increase the cation exchange capacity of the soil, and reduce the salinity of the soil. The time required for chemical improvement is short, the improvement eff...
