Embodiment 1

[0032] The present embodiment provides the preparation method of acidic soil conditioner of the present invention, specifically:

[0033] Step 1. Organic matter fermentation: carry out alkaline fermentation of animal and plant humus, adjust the organic matter content after the fermentation is completed, and dry until the water content is 7%;

[0034] Step 2. adding the animal and plant humus treated in step 1 to the microorganisms, the ratio of actinomycetes, bacillus subtilis, bacillus lateralis, paenibacillus jelly-like, and bacillus amyloliquefaciens in the microorganisms is in accordance with the effective live bacteria Calculated as 20:8:8:6:15, mix evenly, pack, that is to say.

[0035] The organic matter content of the acidic soil conditioner prepared in this embodiment is ≥ 45%, the total content of N, P and K ≥ 5%, and the effective viable bacteria number is not less than 500 million / g.

Embodiment 2

[0037] The present embodiment provides the preparation method of acidic soil conditioner of the present invention, specifically:

[0038] Step 1. Fermentation of organic matter: Alkaline fermentation of animal and plant humus, adjustment of organic matter content after fermentation, and drying until the moisture content is 5%;

[0039] Step 2. adding the microorganisms through the animal and plant humus treated in step 1, the ratio of Bacillus subtilis, Bacillus lateralis, Paenibacillus jelly-like, and Bacillus amyloliquefaciens in the microorganisms is 1 according to the effective live bacteria: 15:2:20, mix evenly, package, and get ready.

[0040] The organic matter content of the acidic soil conditioner prepared in this embodiment is ≥ 45%, the total content of N, P and K ≥ 5%, and the effective viable bacteria number is not less than 500 million / g.

Embodiment 3

[0042] The present embodiment provides the preparation method of acidic soil conditioner of the present invention, specifically:

[0043] Step 1. Organic matter fermentation: carry out alkaline fermentation of animal and plant humus, adjust the organic matter content after the fermentation is completed, and dry until the water content is 10%;

[0044] Step 2. Add the animal and plant humus treated in step 1 to the microorganism, and the ratio of actinomycetes, Bacillus subtilis, Paenibacillus jellylike, and Bacillus amyloliquefaciens in the microorganisms is 30:15 in terms of effective live bacteria : 10: 10, mix evenly, pack, ready to serve.

[0045] The organic matter content of the acidic soil conditioner prepared in this embodiment is ≥ 45%, the total content of N, P and K ≥ 5%, and the effective viable bacteria number is not less than 500 million / g.

Abstract

The invention discloses an acid soil conditioner and a preparation method thereof and solves the problem that the prior art is undesirable in soil pH improvement, little in soil organic matter contentincrease and incapable of improving soil heavy metal pollution. The acid soil conditioner comprises alakaline organic matter and microorganisms, the microorganisms are selected from one or multiple of actinomycetes, bacillus subtilis, bacillus laterosporus, paenibacillus mucilaginosus and bacillus amyloliquefaciens, organic matter content is greater than or equal to 45%, N, P and K total contentis greater than or equal to 5%, and active viable count is not less than 0.5 billion / g. The acid soil conditioner can effectively improve soil pH, can increase soil organic matter content, supplementorganic nitrogen, phosphorus and potassium and mineral elements, increase soil beneficial microorganism flora amount and dissolve, adsorb and sediment soil heavy metal pollutants.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to an acidic soil conditioner and a preparation method thereof. Background technique [0002] Acidification of farmland soil is an inevitable result of intensive agricultural production. Large-scale acidification of farmland soil caused by irrational fertilization is a typical problem caused by high-yield and high-input agriculture in China. The general acidification of farmland soil in China is very serious, especially in the south. According to the analysis of 9.02 million soil sample test data from 2005-2011 soil testing and formula fertilization, compared with the second soil census 30 years ago, the pH value of cultivated land in the country has dropped by 0.13-1.3 units. Among them, 15% of the soil in our country is between PH4.5-5.5, and 5% of the soil is treated below PH4.5. The country found 22.85 million mu of cultivated land below PH4.5, and the top 10 ...
