Composite microbial granular preparation as well as preparation method and application thereof

Abstract

The invention belongs to the technical field of microbial fertilizer preparation, and particularly relates to a composite microbial granular preparation as well as preparation and application thereof.Pig manure, kelp residues, mushroom residues and bran are used as initial raw materials for fermentation to form an organic material; humic acid powder is added into the organic material for granulation; a certain amount of mixed fermentation liquor of bacillus subtilis and bacillus mucilaginosus is sprayed on the particles to finally obtain the composite microbial particle preparation. Results show that the preparation method provided by the invention is simple to operate and easy for mass production. The composite microbial granular preparation not only can promote the rhizosphere development of crops and provide comprehensive nutrition for the crops, but also can improve the disease resistance of the crops, and has certain quality-improving and yield-increasing effects on the crops.

Description

technical field [0001] The invention belongs to the technical field of microbial fertilizers, and in particular relates to a composite microbial granule preparation and a preparation method and application thereof. Background technique [0002] With the continuous improvement of people's living standards, my country's livestock and poultry breeding industry is developing rapidly in the direction of scale and intensification. But at the same time, large-scale farms produce a large amount of manure per day, about 3.8 billion tons of manure per year. Its treatment and storage have become important factors restricting the development of the breeding industry, posing a significant threat to the ecological environment and human health. At present, there are many treatment schemes for pig manure, but there are still many problems. For example, CN105309323 proposes a method for recycling pig manure and urine from polluted agricultural waste without efflux, which involves crushing he...

Problems solved by technology

But at the same time, large-scale farms produce a large amount of manure per day, about 3.8 billion tons of manure per year. Its treatment and storage have become important factors that limit the development of the breeding industry, and pose a significant threat to the ecological environment and human health.

At present, there are many treatment schemes for pig manure, but there are still many problems. For example, CN105309323 proposes a method for recycling pig manure and urine from polluted agricultural waste without efflux, which involves crushing herbal agricultural waste into powdery debris step by step. Segmental debris, then it is mixed with fermented material and pig manure, and the air is continuously fed into it for fermentation. This method has a bad smell and still has problems for environmental pollution; another example is CN108640780, which proposes a resource utilization of pig manure and The treatment method is to separate the solid and liquid of pig manure, spray microbial reagents, dry it, and finally form organic fertilizer. Although it can solve the problem of resource utilization of pig manure, the separation equipment is complicated and cumbersome, and more auxiliary materials are used in the separation process. The operation is cumbersome, the cost is high, and it is not conducive to mass production

[0003] At present, the use of microbial organic fertilizers has become a research hotspot. Although traditional microbial organic fertilizers can promote crop growth to a certain extent, the preparation is complicated and costly, and it is not conducive to mass production.

For example, CN201810390758.9 proposes a method of using kelp slag to prepare organic fertilizer. The kelp slag, chicken manure, and wheat bran are processed by a steam explosion device, and then steam sterilized, and soybean ethanol solution is added to form a conical shape. Although the organic fertilizer produced can promote and regulate the growth of crops, the treatment process of the steam explosion device is complicated, the input cost is high, and it is not suitable for mass production

As another example, the Chinese patent CN201811373677.4 proposes a bio-organic fertilizer production process based on mushroom dregs, using mushroom dregs, wheat bran, peanut bran, etc. after fermentation, adding functional bacteria to continue fermentation, and then granulating to obtain bio-organic fertilizer. Although this bio-organic fertilizer can release the phosphorus and potassium fixed by the soil from the soil, thereby promoting plant growth, the scheme is fermented twice, and the time is long, which is not conducive to mass production; Temperature will also affect the effective number of viable bacteria in the product, resulting in unstable number of viable bacteria
