preparation example Construction

[0022] The preparation method of the mixed biological liquid is as follows: adjust the water content of the peat soil to 70-80%, place it naturally for 2-4 days, collect the peat soil after being placed, and take 120-150 parts of water, 40-45 parts by weight. 1 part of peat soil after standing, 20-25 parts of beef extract, 10-15 parts of sucrose, 3-6 parts of sodium chloride, stir and mix, place at 25-35°C for 30-35 hours, and use sulfuric acid solution to adjust the pH to 3.0 ~4.0, after placing, filter and collect the filtrate to obtain the mixed biological fluid;

[0023] The nutrient solution is calculated in parts by mass. Take 160-180 parts of water, 30-35 parts of peptone, 18-23 parts of yeast extract, and 10-15 parts of glucose, stir and mix, sterilize, and obtain the nutrient solution;

[0024] The preparation method of the additive is as follows: in parts by mass, 140-170 parts of water, 20-25 parts of vermiculite, 10-15 parts of Bacillus subtilis, 6-8 parts of gluco...

Abstract

The invention belongs to the technical field of soil conditioning and particularly relates to a preparation method of a saline-alkaline soil bio-conditioner. The preparation method includes: using leaf mold having developed pores and rich organics as a raw material, activating the raw material with a surfactant, extruding the activated material with additives, tightly combining the additives and the raw material by adding, allowing sulfur in the additives to form sulfides during pre-charring, retaining the sulfides during extrusion, allowing the sulfides to be well sucked to pre-charred particles through magnetic iron oxide, mixing the sucked sulfides with a mixed biological liquid to well suck and support microbes in the mixed biological liquid, subjecting enzymes and bacteria in the microbes to crosslinking and curing via Genipin, and mixing with additives. The additives help effectively improve water-holding performance of soil, and other auxiliaries help improve the soil conditioning effect.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a preparation method of a saline-alkali land biological improver. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization It is generally higher, and plants in severe saline-alkali soil areas can hardly survive. 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 improvemen...
