Embodiment 1

[0041] (1) Preparation of decomposed mixed bacteria: Inoculate the activated Bacillus subtilis and Bacillus thermophilic licheniformis into the culture medium of the Erlenmeyer flask respectively, the inoculation amount is 3-5% (V / V), and inoculate them after 12 hours of cultivation until fermentation Expand the tank culture medium until the number of viable bacteria reaches 10 8 cfu / mL to get Bacillus subtilis culture fluid and thermophilic Bacillus licheniformis culture fluid;

[0042] Among them, the medium components of Bacillus subtilis are based on mass percentage content: glucose 6%, yeast extract 1%, peptone 0.2%, CaCO 3 1%, the rest is water; culture temperature is 28-32℃;

[0043] The medium components of the thermophilic Bacillus licheniformis culture medium are calculated by mass percentage: 0.5% yeast extract, 0.5% peptone, 5% brown sugar, 0.1% Tween-80, 0.05% sodium chloride, 0.05% dihydrogen phosphate Potassium, 0.05% magnesium sulfate, 0.05% calcium carbona...

Embodiment 2

[0056] (1) Preparation of decomposed mixed bacteria: use the steps in the example (1) to obtain the Bacillus subtilis culture solution and the thermophilic Bacillus licheniformis culture solution; Mixed at 1.5:1 to obtain decomposed mixed bacteria;

[0057](2) Preparation of feces straw decomposed clinker: mix pig manure and wheat straw powder evenly at a mass ratio of 3:1 to obtain fermentation raw materials; add decomposed mixed bacteria with an inoculum amount of 8% (g / g) to the fermentation raw materials , adjust the moisture content to 50%, loosely place it in the fermentation tank, and ferment under the condition of 40-45 ° C. During the fermentation process, turn the pile once every 3 days, and ferment for 15 days until it reaches maturity, that is, the decomposed clinker;

[0058] (3) Preparation of culture solution for pathogen-inhibiting bacteria of sugarcane perennial dwarf disease: expand the activated Bacillus thuringiensis according to the method of step (3) in E...

Embodiment 3

[0063] (1) Preparation of decomposed mixed bacteria: use the steps in the example (1) to expand culture to obtain Bacillus subtilis culture fluid and thermophilic Bacillus licheniformis culture fluid; Mixed at 2.5:1 to obtain decomposed mixed bacteria;

[0064] (2) Preparation of feces straw decomposed clinker: mix pig manure and wheat straw powder evenly at a mass ratio of 2.5:1 to obtain fermentation raw materials; add decomposed mixed bacteria with an inoculum amount of 12% (g / g) to the fermentation raw materials , adjust the moisture content to 53%, loosely place it in the fermentation tank, and ferment it under the heat preservation condition of 50-55°C. During the fermentation process, turn the pile once every 3 days, and ferment for 11 days until it reaches maturity to obtain the decomposed clinker;

[0065] (3) Preparation of culture solution for pathogen-inhibiting bacteria of sugarcane perennial dwarf disease: expand the activated Bacillus thuringiensis according to ...

Abstract

The invention discloses a compound microbial-fermented organic fertilizer. The compound microbial-fermented organic fertilizer is prepared through the following steps: mixing pig manure and straw powder, inoculating well-composted mixed bacteria to the mixture, and carrying out compost fermentation, so as to obtain a well-composted material; carrying out amplification culture on bacillus thuringiensis so as to obtain a culture solution for pathogen inhibiting bacteria for perennial root dwarf disease of Saccharum officinarum; carrying out amplification culture on streptomyces globisporus, actinomycetes and brown spherical azotobacteria, and carrying out proportioning mixing, so as to obtain a plant probiotics mixed solution; proportionally mixing bamboo charcoal, diatomite and zeolite powder, so as to obtain a soil amendment; and uniformly mixing the well-composted material, the culture solution for the pathogen inhibiting bacteria for the perennial root dwarf disease of the Saccharum officinarum, the plant probiotics mixed solution and the soil amendment proportionally, and carrying out drying, crushing, sieving and granulating, thereby obtaining the microbial-fermented organic fertilizer. The organic fertilizer provided by the invention is high in fertility, can be used for truly effectively inhibiting the incidence of the perennial root dwarf disease of the Saccharum officinarum and can also be used for amending soil, improving the activity of the soil, increasing the yield of the Saccharum officinarum and shortening the ripening period of the Saccharum officinarum, thereby having very high economic and social benefits.

Description

technical field [0001] The invention relates to the field of fermented organic fertilizers, in particular to a compound microbial fermented organic fertilizer and a preparation method thereof. Background technique [0002] my country is a large agricultural country, with arable land area of ​​about 2.03 billion mu, ranking fourth in the world. As we all know, the development of agricultural production is inseparable from fertilizers, but in recent years, due to excessive agricultural production and unscientific use of chemical fertilizers in my country, the organic matter and trace elements in the soil are seriously deficient, resulting in soil compaction, a decline in the utilization rate of fertilizers, and a decline in the quality of agricultural products. At the same time, adverse phenomena such as environmental pollution and high incidence of pests and diseases have also appeared. [0003] At present, the fertilizers on the market are divided into inorganic fertilizers,...
