This invention discloses a high-humicity microbial fertilizer and its preparation method, belonging to the field of microbial fertilizer technology. The method involves adding a mixed carrier, a protective agent, and fermentation broth to a stirred tank in a specific ratio, followed by shaking and adsorption, filtration, and drying with forced air until the moisture content of the absorbent resin powder reaches 30-35%. The powder is then continuously granulated using a granulator and sieved to obtain microbial agent granules with a particle size of 2-5 mm. The microbial agent granules and sodium humate are mixed at a mass ratio of 1-2:10 to obtain the high-humicity microbial fertilizer. The aggregated short fibers, under the adhesive and physical entanglement effects of the protective agent, increase the internal space of the microbial agent granules while improving structural stability, providing a stable growth and reproduction environment for microorganisms, and improving the long-term storage of the fertilizer and the survival rate of microorganisms after application. The enlarged microbial agent granules provide support, increasing soil looseness and providing a good respiratory environment for crop roots.

The utility model provides a chestnut garden soil improvement deep ploughing device. The chestnut garden soil improvement deep ploughing equipment comprises a supporting plate, a box body is fixedly mounted at the top of the supporting plate, and a balancing weight is arranged in the box body; the sliding rod is installed on the supporting plate in a sliding mode, and a fixing block is fixedly installed at the bottom end of the sliding rod; the sleeve shell is fixedly installed on the fixing block through a bolt, and a deep ploughing plough used for improving the soil of the Chinese chestnut garden is fixedly installed on the sleeve shell. The chestnut garden soil improvement deep ploughing device solves the technical problems that due to the fact that an existing deep ploughing device cannot conduct fertilization in the soil ploughing process, fertilization needs to be conducted additionally or manually if fertilization needs to be conducted after deep ploughing, and then the soil improvement efficiency is affected.
