Abstract

The invention relates to a granular type compound microbial bacterial agent which comprises the following components in percentage by weight: 80-90 percent of powdered compound microorganism bacterial agent, 8-14 percent of phosphate rock powder and 2-6 percent of trace element, wherein the powdered compound microorganism bacterial agent is prepared by adsorbing zymocyte fluid with a single strain respectively with a medical stone, and the strains are bacillus subtilis, bacillus megateria and bacillus mucilaginosus. The invention also provides a preparation method and application of the granular type compound microbial bacterial agent. The invention provides a good carrier for the production of microbial bacterial agent granules; the medical stones have various characteristics of good adsorbability, leachability, mineralization, bioactivity, and the like and provide good carriers for the adsorption of the microbial bacterial agent; a produced fertilizer has better appearance, and the intensity of the fertilizer is obviously enhanced; and the invention greatly improves the utilization rate and the long-term effectiveness of the fertilizer and is beneficial to storing and transporting products.

Description

【Technical field】

[0001] The invention relates to a granular composite microbial bacterial agent and a production method thereof, in particular to a composite microbial bacterial agent using medical stone as an adsorption carrier for microbial fermentation liquid, a production method and application thereof. 【Background technique】

[0002] Medical stone is a loose layered, veined, and lenticular structure formed by the original rock through alteration and weathering. It contains a variety of mineral elements that are beneficial to plant growth and development. It has a large specific surface area and has a porous and Sponge-like structure, at the same time, in these structures, tetrahedrons and octahedrons are arranged alternately, and Al in the lattice 3+ instead of Si 4+ As a result, excess negative charges appear, and additional cations are needed to balance the negative charges. These cations are loosely combined with the crystal lattice, so medical stone has good adsor...
