Problems solved by technology

Make the bacteria in the bacterial agent easily mutate and reduce the fertilizer efficiency in the process of metabolism and reproduction
[0006] (3) After the bacterial agent is mixed with inorganic fertilizers and additives, in addition to easily changing the pH value and carbon-to-nitrogen ratio of the original bacterial agent, it also changes the composition of the bacterial agent medium, making it difficult for the bacteria to reproduce and reducing the survival rate of the bacteria.
This process increases the mortality rate of the viable count of the strain

Embodiment 1

[0033] Get 850kg of inoculum produced by Beijing Century Arms Biotechnology Co., Ltd., the inoculum of Bacillus cereus is powdery, with a fineness of 100% passing through a 60-mesh sieve, and moisture≤25%. Take 150kg of auxiliary material talcum powder, the auxiliary material is powdery, and the fineness is 100% and passes through a 120 mesh sieve, firstly mixed manually, and put into a mechanical mixer to mix until uniform, then transported to the granulator, and then added separately The aqueous solution of binder plastic methyl cellulose is carried out spray granulation (the solution of binder is 8% aqueous solution), and the consumption of aqueous solution is 228kg. The granulated material is sent into the drum dryer for co-current drying with hot drying gas and the material, and the drying time of the material is fixed at 18 minutes. The water content of the product is controlled within the range of 12-16%, and the dried material is sent to the cooler to cool to room temp...

Embodiment 2

[0038] With embodiment 1, wherein bacterium agent 850kg, auxiliary material is bentonite, and consumption is 175kg; The concentration of binder aqueous solution is 5%, and the consumption of aqueous solution is 230kg.

Embodiment 3

[0040] With embodiment 1, wherein bacterial agent is 900kg, and auxiliary material is silicon bath soil, and consumption is 86kg, and binding agent is starch aqueous solution, and concentration is 2%, and consumption is 184kg.

[0041] The composition of granule bacterial agent is as table 2 (dry basis) in each example

[0042] Table 2

[0043]

[0044] The bacteria agent provided by the invention has high strength, convenient and flexible use. The production method is more economical and fast, shortens the granulation time, saves granulation water, and reduces the drying load.

Abstract

The present invention provides a granular microbial preparation and its production method. Its compositions include 65-89.95 wt% of microbial preparation, 10-30 wt% of auxiliary material and 0.05-5 wt% of binding agent, in which the optimum binding agent is plastic methyl cellulose and starch, at the same time said invention also provides production method of said microbial preparation. Said microbial preparation is high in strength and flexible and convenient for application.

Description

technical field [0001] The invention relates to a microbial fertilizer, in particular to a granular microbial agent and a production method thereof. Background technique [0002] Microbial fertilizers have a history of more than 100 years in the world, and 50 years in our country. Especially in the ten years from the mid-1980s to the present, it is the fourth development climax. However, the microbial fertilizers in my country are basically powdery, and the technology is basically that the liquid bacterial liquid is adsorbed with peat that contains a large amount of organic matter in a powdery substance. The product after adsorption is called bacterial agent, also called microbial fertilizer. There are two types of so-called microbial fertilizers. One is pure bacterial agent fertilizer, called AA-grade microbial fertilizer. Most of the AA-grade microbial fertilizers sold in the market in my country are powdery, and there are very few granular products. The other is micro...
