Embodiment 1

[0035] Preparation of improver component A: Take 5% Trichoderma viridans, 5% Candida tropicalis, 8%-15% Bacillus megaterium, and 8% Bacillus colioids to expand culture respectively according to the volume ratio, and obtain four cultures respectively Then inoculate the culture solution into the fermenter according to the volume of 10% to carry out liquid culture respectively, the culture temperature is 25 ℃, and the culture time is 24h, respectively to obtain four kinds of bacterial suspensions; the four kinds of bacterial suspensions: 2% cellulase Liquid, 3% lignin enzyme liquid, 2% protease liquid, 67% biochemical fulvic acid liquid can be mixed according to the ratio of component A of the improver.

[0036] Preparation of improver component B: Mix 65.5% temperature-sensitive hydrogel and 2% hydrogel synergist evenly. Under the protection of an inert atmosphere, pass 100°C water vapor into high temperature treatment for 20 minutes, and then cool down at 10°C / min to 10°C and k...

Embodiment 2

[0045] This embodiment is basically the same as Embodiment 1, the difference is:

[0046] (1) Improver component A includes: 5% cellulase liquid, 5.5% lignin enzyme liquid, 5% protease liquid, 7.5% Trichoderma viride suspension, 7.5% Candida tropicalis suspension according to volume percentage Liquid, 11.5% Bacillus megaterium suspension, 10% Bacillus colloidus suspension, 48% biochemical fulvic acid solution;

[0047] (2) Improver component B includes 13.5% water-soluble lubricating liquid, 8% water-soluble metal chelating agent, 3% hydrogel synergist, 4% carbon dioxide foaming agent, 1% dispersant, 11% Biomass extract, 59.5% thermosensitive hydrogel particles.

[0048] (3) The water-soluble lubricating fluid is a chitosan-type lubricating fluid.

[0049] (4) Take corn as the test object. Before planting, plow the saline-alkali land 45cm deep and turn over the soil. According to the dosage of 20L per mu, add the amendment component B to 43°C water to dilute 40 times, and us...

Embodiment 3

[0056] This embodiment is basically the same as Embodiment 1, the difference is:

[0057] (1) Improver component A includes: 8% cellulase liquid, 8% lignin enzyme liquid, 8% protease liquid, 10% Trichoderma viride suspension, 10% Candida tropicalis suspension according to volume percentage liquid, 15% suspension of Bacillus megaterium, 12% suspension of Bacillus colioids, 29% biochemical fulvic acid solution;

[0058] (2) Improver component B includes 15% water-soluble lubricating liquid, 9% water-soluble metal chelating agent, 4% hydrogel synergist, 5% carbon dioxide foaming agent, 1.5% dispersant, 10% ~12% biomass extract, 535% thermosensitive hydrogel particles.

[0059] (3) The water-soluble lubricating fluid is an aloe-type lubricating fluid.

[0060] (4) Take tomato as the experimental object. Before planting, plow the saline-alkali land 50cm deep and turn over the soil. According to the dosage of 20L per mu, add the improvement agent component B to 45°C water to dilut...

Abstract

The invention discloses a saline-alkali land soil biological improvement agent as well as a preparation method and application thereof. The improvement agent comprises an improvement agent component Aand an improvement agent component B, wherein the improvement agent component A comprises the following components in percentage by volume: 2 to 8 percent of cellulase, 3 to 8 percent of ligninase, 2to 8 percent of protease, 5 to 10 percent of trichoderma viride bacterial suspension, 5 to 10 percent of candida tropicalis bacterial suspension, 8 to 15 percent of bacillus megatherium bacterial suspension, 8 to 12 percent of bacillus mucilaginosus bacterial suspension and the balance of biochemical fulvic acid liquid; the improvement agent component B comprises the following components in percentage by volume: 12 to 15 percent of water-soluble lubricating liquid, 7 to 9 percent of water-soluble metal chelating agent, 2 to 4 percent of hydrogel synergist, 3 to 5 percent of a carbon dioxide foaming agent, 0.5 to 1.5 percent of a dispersing agent, 10 to 12 percent of biomass extracting liquid and the balance of temperature-sensitive hydrogel particles. The microorganisms and the temperature-sensitive hydrogel are cooperatively applied before and during planting of plants, so that the condition of the saline-alkali land can be improved and the yield of plants can be increased.

Description

technical field [0001] The invention belongs to the technical field of soil restoration and improvement, and in particular relates to a saline-alkaline soil biological improver and its preparation method and application. Background technique [0002] The problems of soil salinization and secondary salinization are widespread in the world, especially in arid and semi-arid areas, where the problem is more serious. According to incomplete statistics from UNESCO and FAO, the area of ​​saline-alkali land in the world is 954 million hectares, of which 99.13 million hectares is in China. China has a large amount of saline-alkali land, distributed in Northwest China, North China, the western part of Northeast China and the coastal areas. Land salinization not only endangers the soil conditions on which crops rely for survival, but also inhibits the growth and development of crops, resulting in lack of seedlings, reduced production, and death. hinder the development of agricultural ...
