Problems solved by technology

Conventional microbial fertilizers are available in liquid and solid (powder) formulations. Although the production cost of liquid fertilizers is relatively low, they have a short shelf life, are prone to qualitative changes, and have disadvantages such as liquid leakage and inconvenient transportation.
Although solid fertilizers have a longer shelf life, are less likely to undergo qualitative changes, and are more convenient to transport than liquid fertilizers, when powders are applied, they tend to disperse with the wind and cause dust to fly, which can easily cause the human body to inhale excessive powders; in addition, the application is easily restricted by the terrain factors that affect the efficiency of use

Embodiment Construction

[0019] see figure 1 As shown, it is a step of an embodiment of the present invention. The manufacturing method of a kind of biological fertilizer granule preparation of the present embodiment, it comprises the following steps.

[0020] Step A is the liquid state fermentation of strains, which inoculates a microorganism to carry out fermentation to mass-produce microbial spores. Phosphorus or algae. In step A, a fermentation vessel can be used to contain a liquid medium, which is inoculated with the microorganism after being sterilized, wherein the fermentation vessel can be a Erlenmeyer flask, a serum bottle, a fermenter or other vessels that can be used for liquid fermentation. The sterilization procedure of step A is to put the liquid culture medium into the fermentation vessel, and then sterilize it by high temperature and high pressure sterilization method or boiler steam sterilization method.

[0021] Step B is to make half of the finished bacterial powder. First, the ...

Abstract

A preparing method of biological fertilizer bacterium granules is disclosed. Microbial spores are produced by liquid fermentation by utilization of a bacterium strain, and are then collected. A semi-finished bacterium powder product is prepared by freeze-drying, powder milling, and other steps, or semi-finished bacterium powder is prepared by directly spraying drying. The semi-finished bacterium powder comprises an excipient and an extender, and is prepared into the biological fertilizer bacterium granules by using a granulator.

Description

technical field [0001] The invention relates to a method for manufacturing a biological fertilizer granule, in particular to a method for manufacturing a biological fertilizer granule that can protect the ecological environment, has high stability, is resistant to storage and is convenient for transportation. Background technique [0002] Chemical fertilizers and chemical pesticides are mostly used in the cultivation of crops. Long-term application of chemical fertilizers or chemical pesticides will easily acidify and solidify the soil or drastically reduce the number of beneficial microorganisms and earthworms in the soil, resulting in damage to the soil texture, water storage and conservation. Fertilizer capacity is reduced, which affects the growth of crops. The ability of crops that absorb excessive chemical fertilizers to resist diseases and adversities will also decrease, leading to increasingly serious crop diseases and insect pests, and the application of chemical pe...
