Embodiment 1

[0036] A microbial composite inoculum, the raw materials of which are composed of the following components in parts by weight: 40 parts of Bacillus subtilis fermentation broth, 25 parts of Bacillus mycoides fermentation broth, 15 parts of Coral Xenocarpus fermentation broth , 15 parts of functional bacteria, 70 parts of carrier;

[0037] The specific preparation method is as follows:

[0038] Step 1. Prepare Bacillus subtilis seed liquid, Bacillus mycoides seed liquid and Coral Xenocarpa seed liquid respectively;

[0039] Step 2. Preparation of Bacillus subtilis fermentation broth

[0040] The mulberry leaf, silkworm excrement and fish meal are uniformly mixed according to the mass ratio of 10:3:1 and then ground into powder, and then passed through an 80-mesh sieve to obtain the mixed raw material powder; the mixed raw material powder, wood vinegar liquid and water according to 15:1: Mix evenly with a mass ratio of 20 to obtain Bacillus subtilis culture medium;

[0041] Inoculate the...

Embodiment 2

[0052] A microbial composite inoculum, the raw materials of which are composed of the following components in parts by weight: 50 parts of Bacillus subtilis fermentation broth, 30 parts of Bacillus mycoides fermentation broth, and 10 parts of Coral Xenocarpus fermentation broth , 10 parts of functional bacteria, 60 parts of carrier.

[0053] The preparation method is the same as in Example 1, except that the formula is changed to the formula of the microbial composite inoculum of Example 2, and the moisture content of the prepared microbial composite inoculum is 10%.

Embodiment 3

[0055] A microbial composite inoculum, the raw materials of which are composed of the following components in parts by weight: 30 parts of Bacillus subtilis fermentation broth, 20 parts of Bacillus mycoides fermentation broth, and 20 parts of Coral Xenocarpus fermentation broth , 20 parts of functional bacteria, 80 parts of carrier.

[0056] The preparation method is the same as in Example 1, except that the formula is changed to the formula of the microbial composite inoculum of Example 3, and the moisture content of the prepared microbial composite inoculum is 8%.

[0057] It should be noted that the number of effective viable bacteria in the fermentation broth of Bacillus subtilis, the number of effective viable bacteria in the fermentation broth of Bacillus mycoides, and the number of effective viable bacteria in the fermentation broth of Xenocarpus corallinea are all ≥10 11 cfu / mL;

[0058] The functional inoculum is a mixture of nitrogen-fixing bacteria and rhizobia in a mass r...

Abstract

The invention discloses a complex microbial inoculant. The complex microbial inoculant comprises, by weight, 30-50 parts of bacillus subtilis fermented liquid, 20-30 parts of bacillus mycoides fermented liquid, 10-20 parts of coral nocardiaceae fermented liquid, 10-20 parts of functional microbial inoculants and 60-80 parts of carriers. The invention further provides a preparation method and application of the complex microbial inoculant. The prepared complex microbial inoculant has the advantages that the complex microbial inoculant contains enough effective viable bacteria and can take effect stably and efficiently; by the complex microbial inoculant, the soil organic matter and the content of nutritional elements such as nitrogen, phosphorus and potassium can be increased remarkably, nutrient conversion rate and the number of beneficial microorganisms in products can be also increased, soil remediation can be promoted, soil fertility can be improved, and consumption of chemical fertilizer can be reduced; disease resistance of crops can be enhanced, crop quality can be improved, investment can be reduced, and yield and income can be increased.

Description

Technical field [0001] The invention belongs to the technical field of agricultural microorganisms, and specifically relates to a microbial composite microbial agent and a preparation method and application thereof. Background technique [0002] Agricultural fertilizers include chemical fertilizers and microbial fertilizers. Microbial fertilizer is a product that results in a specific fertilizer effect due to the action of microbial life activities. It is essentially different from traditional chemical fertilizers and organic fertilizers. Microbial fertilizer is made by mixing microbial inoculants and microbial fertilizer formula. It has low production cost, convenient use, good application effect, improves the soil environment, does not pollute the environment, and not only increases production after application, but also improves the quality of agricultural products and reduces the amount of fertilizer applied. [0003] After the problems of soil compaction, fertility decline, so...
