Problems solved by technology

Existing powdery bio-organic fertilizers have many disadvantages: 1, powdery bio-organic fertilizers have a relatively high water content (> 30% or even higher) due to no drying procedure, resulting in short product shelf life (less than 6 months), It cannot be stored for a long time and deteriorates (such as agglomeration, mildew, etc.); 2. Due to the high water content of the powdered bio-organic fertilizer, the microorganisms contained in it will germinate or even die in large quantities during the storage period of the product, causing the product to lose its due value. 3. Due to the characteristics of organic matter itself (such as black color, impurities, smell, etc.), some users do not like to use powdery bio-organic fertilizers, and even refuse to use them because they think they are garbage or fakes; 4. Powdery bio-organic fertilizers Organic bio-fertilizers are not suitable for spreading, especially in areas with strong winds, so they can only be mixed into water or flushed; 5. Powdered bio-organic fertilizers cannot be broadcast by machine, and cannot be applied to modern agriculture that is heavily used by mechanization
However, most of the existing bio-organic fertilizers are still in the form of powder, and cannot be made into granules by high-temperature (generally 100-150°C) granulation and drying methods, because the effective living bacteria of microbial agents in organic fertilizer raw materials will During the high-temperature granulation drying process and the loss of physiological activity due to the high inorganic salt content in the raw material formula, the number of effective viable bacteria in the finished fertilizer cannot reach the industry standards for bio-organic fertilizers of NY884-2004 and compound microbial fertilizers of NY798-2004 Technical standard greater than or equal to 20 million pieces / gram

Abstract

The invention discloses a granular biological organic fertilizer and a preparation method thereof. The fertilizer is prepared from the following raw materials in parts by weight: 400-650 parts of a nutritional organic material, 5-10 parts of a microbial agent, 0-200 parts of an inorganic fertilizer, 0-250 parts of kaolin and 0-200 parts of peat cube, wherein the nutritional organic material is prepared from waste yeast fermentation broth and rice bran in the weight ratio of (0.8-1.2):(1.2-0.8); and the microbial agent is prepared from bacillus lateraporus powder, zeolite powder and bentonite in the weight ratio of 1:(0.3-0.7):(0.7-0.3). The preparation method comprises the following steps of: (1) uniformly mixing the waste yeast fermentation broth with the rice bran, and fermenting to obtain the nutritional organic material; (2) uniformly mixing the bacillus lateraporus powder, zeolite powder and bentonite to obtain the microbial agent; and (3) uniformly mixing the raw materials, pelletizing an obtained mixture, drying at the temperature of 100-150 DEG C, and screening to obtain a finished product. The quantity of viable bacteria in the fertilizer can reach the technical standard of more than or equal to two million of pieces per gram specified by a relevant industrial standard.
