preparation example Construction

[0030] The preparation method of described attapulgite soil conditioner, comprises the following steps:

[0031] S1: After drying the corn stalks, mix the ore soil filler and coal stalks, put them into a pulverizer and grind them, and pass through a 50-mesh sieve to obtain the mixed material A;

[0032] S2: Mix the mixed material A with the mixed grass powder, stir evenly at a speed of 200-300r / min, add compound microorganisms and humic acid to ferment, ferment at a temperature of 50-60°C, and ferment for 15-20 days to obtain Mixture B;

[0033] S3: Weigh dimethyl diallyl ammonium chloride in proportion, dissolve it in water at 55-65°C, quickly add attapulgite, then add 2 parts of sulfuric acid, stir at constant temperature for 1-2h, then wash with ethanol Wash and centrifuge, then put it into a muffle furnace for calcination for 2 hours, and crush it to 200 mesh to obtain modified attapulgite;

[0034] S4: Mix mixed material A, mixed material B, modified attapulgite, urea, am...

Abstract

The invention discloses an attapulgite soil conditioner and belongs to the technical field of soil conditioners. The attapulgite soil conditioner comprises the following raw materials of ore soil filler, coal gangue, maize straws, mixed grass meal, compound microorganisms, humic acids, urea, ammonium dihydrogen phosphate, potassium chloride, flue gas desulfurization gypsum, attapulgite, dimethyl diallyl ammonium chloride, calcium carbonate and polyacrylic acid ultra-porous hydrogel particles. The attapulgite soil conditioner disclosed by the invention has the advantages that the pH value of the soil improved by the attapulgite soil conditioner is more suitable for plant growing, and the survival rate and year increment of the plant are promoted by applying a reinforcing system consisting of dimethyl diallyl ammonium chloride, calcium carbonate and polyacrylic acid ultra-porous hydrogel particles to the attapulgite soil conditioner.

Description

technical field [0001] The invention belongs to the technical field of soil improvers, and in particular relates to an attapulgite soil improver and a preparation method thereof. Background technique [0002] Soil improver is an additive that can improve soil properties. Soil improver was originally only studied for some saline-alkali lands and desertified areas where it is difficult to grow plants, but now it is mainly used for soil pollution and farmland degradation. Domestically produced soil improver raw materials are mainly composed of natural minerals, industrial by-products, agricultural waste, organic fertilizers, organic waste, biomass, artificial polymers and other materials, which contain rich and high-value active bacteria and have the effect of improving soil structure . Part of the soil improver is composed of a variety of probiotics, which can greatly increase the beneficial bacteria in the soil and restore the diversity of soil microbial communities, enhance...
