Problems solved by technology

Because peat contains high humic acid, especially when the granular compound microbial agent is mixed with urea and compound fertilizer for mechanical fertilization, a chemical reaction will occur, and crystal water will be released, and humate mucus will be produced at the same time, which will compound Microbial agent particles are bonded with compound fertilizer or urea to form a wet and sticky material, which can reach a slimy state. When used for mechanical fertilization, the feeding port will be blocked and the fertilizer cannot be spread normally. At the same time, it is not convenient to fertilize by other methods.

Embodiment 1

[0019] The powdery composite microbial bacterial agent (Bacillus cereus and silicate bacteria, produced by Beijing Century Arms Biotechnology Co., Ltd.) accounts for 68% of the total weight, and each batching takes 680 kg.

[0020] The binder attapulgite (fineness greater than 120 mesh) accounts for 25% of the total weight, and each batching takes 250 kg.

[0021] Urea (agricultural use) accounts for 7% of the total weight, and each batching takes 70 kilograms.

[0022] A total of 1,000 kg, after mixing evenly, add water to granulate, dry, cool, and sieve.

[0023] The particle diameter of the prepared composite microbial bacterial agent particle is 2-4.75 mm, the surface is smooth and the strength is high. When the above-mentioned granular compound microbial inoculum is used during mechanical fertilization, no bonding occurs.

Abstract

The invention provides a production method for a granular composite microbial inoculant, which comprises the following steps: 65 to 80 weight percent of powdery composite microbial inoculant, 5 to 30 weight percent of an adhesive and 5 to 15 weight percent of carbamide or mixture of carbamide and ammonium hydrogen carbonate are weighed; the materials are then mixed, granulized by adding with water, dried, cooled and sieved to be made into the granular composite microbial inoculant. As the granular composite microbial inoculant obtained by adopting the production method of the invention does not bond or react with various fertilizers when in mixing, the granular composite microbial inoculant is suitable for mechanical fertilizing.

Description

technical field [0001] The present invention relates to a production method of a granular composite microbial bacterial agent and its products, in particular to a granular composite microbial bacterial agent that does not bond or chemically react when mixed with various chemical fertilizers and is suitable for mechanical fertilization. Production methods and their products. Background technique [0002] There are generally two types of appearances of the existing agricultural solid composite microbial inoculum: one is powdery, and the other is granules with a diameter of 2-4.75 mm that are mechanically manufactured with the powdery microbial inoculum. At present, the carriers used in solid composite microbial bacterial agents are basically peat. Existing granular compound microbial bacterial agents on the market are manufactured by mixing powdery compound microbial bacterial agents and binders through granulation, drying, and sieving, which are completely physical changes. ...
