Problems solved by technology

However, the microbial organic compound fertilizers currently on the market are mainly made of weathered coal, lignite, etc. as organic raw materials, and then added some chemical fertilizers. Although weathered coal, lignite, etc. contain a large amount of organic matter, such substances are generally water-soluble and The physiological activity is very low, and the decomposition is slow after being applied to the soil. It is not easy for crops to absorb, and cannot change the soil structure and enrich the organic matter of the soil.

Embodiment Construction

[0017] The microbial organic compound fertilizer of the present invention uses fermented and decomposed cow dung and rice bran powder as organic raw materials, adds chemical fertilizers and mixes them, then uses low temperature (65-70°C) roller extrusion to granulate, and then sprays the granules with amino acids Envelope, 700 to 900 million / g microbial agents are implanted on the envelope, including plant growth-promoting bacteria, bacillus and actinomycetes.

[0018] The formula of organic-inorganic compound fertilizer is as follows:

[0019] Decomposed cow dung and rice bran powder (organic raw materials) 29 ~ 36kg;

[0020] Ammonium sulfate 4 ~ 9 kg;

[0021] Urea 15 ~ 19 kg;

[0022] Monoammonium phosphate 8 ~ 11 kg;

[0023] Bio-phosphate fertilizer 11-13 kg;

[0024] MSG leftovers 13 ~ 17kg;

[0025] Ammonium chloride 6 ~ 15kg.

[0026] The fermentation process is as follows:

[0027] 1) Mixing of raw and auxiliary materials: add 26% to 31% of straw or husked cha...

Abstract

The invention relates to a microbial organic composite fertilizer. The microbial organic composite fertilizer is prepared by mixing organic raw materials with a chemical fertilizer, then carrying out double-roll extrusion and granulation at a low temperature (65 to 70 DEG C), carrying out guniting and coating on obtained particles by using amino acids, and inoculating a coating film with 0.7 to 0.9 billion of microbial inocula per g of the film, wherein the microbial inocula comprise plant growth-promoting rhizobacteria, Bacillus spp and actinomyces. The microbial organic composite fertilizer provided by the invention integrates an organic fertilizer, the chemical fertilizer and microbes together and has the advantages of strong and long-lasting fertility, high utilization rate, capacity of repairing and improving soil structures, enriching organic matters in soil, improving crop quality and increasing output, etc.

Description

technical field [0001] The invention relates to a microbial organic compound fertilizer. Background technique [0002] At present, the application of microbial organic compound fertilizer is becoming more and more common. However, the microbial organic compound fertilizers currently on the market are mainly made of weathered coal, lignite, etc. as organic raw materials, and then added some chemical fertilizers. Although weathered coal, lignite, etc. contain a large amount of organic matter, such substances are generally water-soluble and The physiological activity is very low, and it decomposes slowly after being applied to the soil. It is not easy for crops to absorb, and cannot change the soil structure and enrich the organic matter of the soil. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings, provide microbial bacteria organic compound fertilizer, which is convenient for crops to absorb nutrients, ...
