Preparation method of high-efficient decay-promoting agent

Abstract

The invention discloses a preparation method of a high-efficient decay-promoting agent. The preparation method comprises the three steps of activation and purification of bacteria, enlarged culture of a liquid shaking table and preparation of solid bacterial powder, and comprises the concrete steps of inoculating fungi, actinomycetes and bacteria on respective culture media, and carrying out streak culture; picking single colonies of the bacteria and the actinomycetes or mycelia or spores of the fungi to inoculate into respective prepared liquid culture media, and culturing through the liquid shaking table; finally inoculating each bacterium of each liquid culture medium into a prepared culture material according to the proportion, dry-curing, mixing the dry-cured bacteria according to the proportion, and preparing the high-efficient decay-promoting agent with high fertility. The invention provides the preparation method of the high-efficient decay-promoting agent, which has the characteristics of capability of enabling the decomposing speed of straw or farmyard manures to be improved remarkably, high degradation ability, high decay promoting efficiency, and good effect.

Description

technical field [0001] The invention belongs to the technical field of corrosion accelerators, and in particular relates to a preparation method of high-efficiency corrosion accelerators. Background technique [0002] Using straw or farmyard manure to make organic fertilizer or directly composting and returning straw or farmyard manure to the field requires the addition of rot accelerators to make the raw materials decompose quickly. The process of straw or farmyard manure to promote decay mainly involves microorganisms and enzymatic degradation processes. The bacteria continuously decompose and transform straw and farmyard manure. The degradation products of straw or farmyard manure are rich in nutrients such as nitrogen, phosphorus and potassium, which can be used for crop growth. This means that the higher the activity of the beneficial bacteria in the rot accelerator, the faster it can promote the rot of straw and farmyard manure, and the better the effect of the rot acc...

Problems solved by technology

Although it is disclosed that the preparation of various bacterial strains is prepared by inoculating the bacterial strains into the prepared respective liquid medium for cultivation, the bacterial strains cultivated in these mediums are not highly active, and the preparation method is to directly inoculate the various bacterial strains The first-level culture seed liquid and the sub-inoculation liquid culture were mixed in proportion and carried out shaker culture to obtain the second-level culture solution. The first-level culture was cultured on a shaker without streak culture, and single colonies were not isolated and selected. The primary culture has not been purified, so the bacteria in the secondary culture are not high in purity and activity

Although it can degrade the straw remaining in the farmland, the obtained bacterial agent degrades the straw slowly, and the efficiency of promoting decay is low.
