Embodiment 1

[0035] Preparation of modifier component A: Take 5% Trichoderma viride, 5% Candida tropicalis, 8%-15% Bacillus megaterium, and 8% Bacillus glacius respectively for expansion culture according to the volume ratio to obtain four cultures respectively. Then the culture solution was inoculated into the fermentor according to the volume of 10% for liquid culture. The culture temperature was 25℃ and the culture time was 24h to obtain four bacterial suspensions; the four bacterial suspensions: 2% cellulase Mix the liquid, 3% ligninase solution, 2% protease solution, and 67% biochemical fulvic acid solution according to the ratio of the modifier component A.

[0036] Preparation of modifier component B: 65.5% temperature-sensitive hydrogel and 2% hydrogel synergist are mixed uniformly. Under the protection of an inert atmosphere, 100 ℃ water vapor is introduced for high temperature treatment for 20 minutes, and then the temperature is reduced at 10 ℃ / min Heat to 10°C and keep for 10 minu...

Embodiment 2

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

[0046] (1) Component A of the modifier includes 5% cellulase, 5.5% ligninase, 5% protease, 7.5% Trichoderma viride suspension, 7.5% Candida tropicalis suspension, 11.5 % Bacillus megaterium suspension, 10% Bacillus mucilaginous suspension, 48% biochemical fulvic acid solution;

[0047] (2) Improver component B includes 13.5% water-soluble lubricating fluid, 8% water-soluble metal chelating agent, 3% hydrogel synergist, 4% carbon dioxide foaming agent, 1% dispersant, 11% by volume percentage Biomass extract, 59.5% temperature-sensitive 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, deep plough the saline soil 45cm and turn the soil. According to the amount of 20L per mu, add the modifier component B to 43℃ water to dilute 40 times, and use the ultrasonic bubbler to carry out ...

Embodiment 3

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

[0057] (1) Improver component A includes 8% cellulase, 8% ligninase, 8% protease, 10% Trichoderma viride suspension, 10% Candida tropicalis suspension, 15% by volume percentage. % Bacillus megaterium suspension, 12% Bacillus mucilaginous suspension, 29% biochemical fulvic acid solution;

[0058] (2) Improver component B includes 15% water-soluble lubricating fluid, 9% water-soluble metal chelating agent, 4% hydrogel synergist, 5% carbon dioxide foaming agent, 1.5% dispersant, and 10% by volume percentage ~12% biomass extract, 535% temperature-sensitive 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, deep plow 50cm of saline-alkali land and turn the soil. According to the amount of 20L per mu, add the modifier component B to 45℃ water to dilute it by 50 times, and use an...

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 specifically relates to a saline-alkali soil biological amendment and a preparation method and application thereof. Background technique [0002] The problems of soil salinization and secondary salinization are widespread worldwide, especially in arid and semi-arid areas, where the problem is more serious. According to incomplete statistics from the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the Food and Agriculture Organization (FAO), the world's saline land area is 954 million hectares, of which 99.13 million hectares are in China. China has a large amount of saline-alkali ground, which is distributed in the northwest, north China, western northeast and coastal areas. The salinization of land not only harms the soil conditions on which crops depend, but also inhibits the growth and development of crops, resulting in lack of seedlings, r...
