Microorganism-containing fertilizer produced by mycoderm method and production method of fertilizer

Abstract

The invention provides to a microorganism-containing fertilizer produced by a mycoderm method and a production method of the fertilizer. In the prior art, microorganism bactericides, organic matters, chemical fertilizer and the like are mixed according to a preset formula, and the mixture is subjected to granulation, high-temperature drying, screen separation, cooling and the like so as to produce a finished product. In the production method provided by the invention, the fertilizer without bactericides is granulated, dried, screened and cooled; active bacterium powder is coated on the outer surface of the fertilizer particles at the tail end of the production line by using a film technology; and the microbial content of the whole fertilizer when in detection reaches the technical standard of national regulation so that a film fertilizer is formed. The method provided by the invention is used for producing the fertilizer with active bacterium.

Description

Technical field: [0001] The invention relates to an organic fertilizer, an inorganic fertilizer or a compound fertilizer with active bacteria and a preparation method thereof. Background technique: [0002] In order to produce organic fertilizers or organic-inorganic compound fertilizers containing active microorganisms, the usual method is: mix microbial agents, organic matter, chemical fertilizers and other materials according to preset formulas, and then go through granulation, high-temperature drying, screening, cooling and other processes Made into a finished product. The problem with this production process is that in the process of processing, multiple processes will cause damage to microorganisms in varying degrees, resulting in death, especially in the high temperature drying process, which often causes a large number of microorganisms to die due to high temperature, and the number of deaths is difficult to determine and control, resulting in different microorganism...

AI Technical Summary

Problems solved by technology

The problem with this production process is that in the process of processing, multiple processes will cause damage to microorganisms to varying degrees, resulting in death, especially in the high temperature drying process, which often causes a large number of microorganisms to die due to high temperature, and the number of deaths is difficult to determine and control, resulting in different Bacteria counts vary greatly between batches of products, making it difficult to maintain stable and consistent product quality

However, the problems of the improved process are: the price of low-temperature drying equipment such as fluidized bed is high, the power consumption is large, and the equipment capacity is low, which increases the investment in equipment and the production cost of products.

Such a large amount of crude bacterial agent can only be added when batching
