Abstract

A vegetation concrete improved microbial agent comprises the following raw materials in parts by weight: a mixed microbial fermentation powder, bentonite, diatomite, magnesium sulfate, zinc sulfate and boric acid, wherein the mixed microbial fermentation powder is prepared by the steps of carrying out press filtration, flash evaporation and drying of amplified cultured azotobacter chroococcum, bacillus megatherium and bacillus mucilaginosus, to respectively obtain dry powders of azotobacter chroococcum, bacillus megatherium and bacillus mucilaginosus, and mixing the dry powders according to a certain proportion. The vegetation concrete improved microbial agent and the preparation method thereof provided by the invention can solve the problem that the number and types of microorganisms cannot be increased as soon as possible; through the proportion of different beneficial microorganisms, a physicochemical environment of soil is changed, the biological chemical activity of the soil is improved, the fertilizer utilization ratio and the use effect are improved, ultimately, the growth of plants is promoted, and the purpose of the vegetation concrete fertility sustainability is achieved.

Description

technical field [0001] The invention relates to the technical field of microbial bacterial agents, in particular to an improved microbial bacterial agent for vegetation concrete and a preparation method thereof. Background technique [0002] With the rapid development of domestic infrastructure, the excavation of slopes caused by large-scale engineering activities can be seen everywhere, which has brought a series of negative impacts on the ecological environment and has become an important factor restricting engineering construction. How to realize the sustainable development of regional economic development on the basis of protecting the ecological environment has become the focus of attention in the engineering field, and a wide variety of slope protection technologies have emerged as the times require. Traditional engineering slope protection technology can provide support and reinforcement measures for slopes, but lacks ecological effects. Ecological slope protection t...
