Problems solved by technology

[0003] At present, the commonly used substances for improving acidic soil mainly include quicklime, phosphogypsum, fly ash, green manure, etc. These substances can only temporarily change the soil pH value, and the soil is prone to acidification again. Therefore, the improvement effect is poor; and the commonly used improvement The acid soil method is a long-term and slow process, and the deacidification improvement process takes a long time

preparation example Construction

[0040] The present invention also provides the preparation method of above-mentioned soil conditioner, comprises the following steps:

[0041] (1) Bacillus glial bacillus is inoculated in the aseptic seed culture liquid, cultivates, obtains the seed liquid that bacillus glial bacillus produces;

[0042] (2) inoculate the seed liquid of bacillus colloidus described in step (1) in the production medium, cultivate, and obtain bacterial agent;

[0043] (3) Wheat bran powder and bone meal are mixed and sterilized to obtain an adsorption matrix;

[0044] (4) Spray the bacterial agent described in step (2) on the adsorption matrix described in step (3), to obtain fermented material;

[0045] (5) mixing the fermentation material described in step (4) with calcined ore powder, light calcium carbonate and plant ash to obtain a soil conditioner;

[0046] The steps (1) (2) and (3) are not in chronological order.

[0047] The present invention inoculates the colloid bacillus in the asepti...

Embodiment 1

[0060] (1) The effective number of viable bacteria for preparing bacillus coliformis is 6×10 9 CFU / mL of bacterial agent;

[0061] (2) Mix wheat bran powder and bone meal in a ratio of 3:2 to obtain an adsorption matrix;

[0062] (3) Spray the bacterial agent on the adsorption substrate according to the mass ratio of 1:20 to obtain the fermented material.

[0063] (4) Mix fermented material, ore powder, light calcium carbonate and plant ash in a mass ratio of 7:7:4:2, extrude and granulate to obtain a soil conditioner.

[0064] The pH value of the soil improver is 11, the organic matter content is 15%, and the number of live bacteria is 300 million / g.

Embodiment 2

[0066] (1) The number of effective viable bacteria for preparing bacillus coliformis is 3×10 9 CFU / mL of bacterial agent;

[0067] (2) Mix wheat bran powder and bone meal in a ratio of 2:1 to obtain an adsorption matrix;

[0068] (3) Spray the bacterial agent on the adsorption substrate according to the mass ratio of 1:25 to obtain the fermented material.

[0069] (4) Mix fermented material, ore powder, light calcium carbonate and plant ash in a mass ratio of 7:6:4:3, extrude and granulate to obtain a soil conditioner.

[0070] The pH value of the soil improver is 10, the organic matter content is 15%, and the number of viable bacteria is greater than or equal to 0.5 billion / g.

Abstract

The invention belongs to the technical field of microbial preparations, and particularly relates to a soil conditioner as well as a preparation method and application thereof. The soil conditioner isprepared from, by mass, 25-35 parts of calcined ore powder, 15-20 parts of light calcium carbonate, 15-20 parts of wheat bran powder, 10-20 parts of bone meal, 10-15 parts of plant ash and 2-5 parts of a microbial inoculum. The microbial inoculum comprises bacillus mucilaginosus. The acid soil conditioner provided by the invention can be used for quickly and effectively improving acid soil; the problems of soil hardening and continuous cropping can be solved, the soil fertility is improved, the resistance of crops is enhanced, and diseases are reduced.

Description

technical field [0001] The invention belongs to the technical field of microbial preparations, in particular to a soil conditioner and its preparation method and application. Background technique [0002] Nowadays, my country's agricultural industry is developing rapidly, and intensive agriculture based on plastic vegetable greenhouses and solar greenhouses has developed rapidly, and has achieved good economic and social benefits. Due to planting habits, technical limitations and market reasons, farmers often plant a single crop in the same greenhouse for a long time, coupled with unreasonable water and fertilizer management and crop pest control technology, the ensuing soil acidification, salinization, element imbalance, lingering Problems of soil degradation such as soil disturbance and pollution have become increasingly prominent, seriously restricting the development of land productivity, affecting environmental quality, and endangering human health. Acidic soil in my c...
