Problems solved by technology

However, the organic-inorganic 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, the decomposition is slow after being applied to the soil, the crops are not easy to absorb, and it cannot change the soil structure and enrich the organic matter of the soil

Embodiment Construction

[0017] The organic-inorganic 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, and adopts low-temperature (60-65° C.) roller extrusion to granulate, and then sprays the granules with amino acids. The membrane is implanted with 600-800 million / g of microbial agents on the envelope, and the microbial agents include 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) 28-35kg;

[0020] Ammonium sulfate 3-8 kg;

[0021] Urea 14-18 kg;

[0022] Monoammonium phosphate 7-10 kg;

[0023] Bio-phosphate fertilizer 10-12 kg;

[0024] MSG leftovers 12-16kg;

[0025] Ammonium chloride 5-14kg.

[0026] The fermentation process is as follows:

[0027] 1) Mixing of raw and auxiliary materials: add 25% to 30% ...

Abstract

The invention relates to an organic and inorganic compound fertilizer, which is characterized by being prepared by the steps of: adding chemical fertilizer into an organic raw material, mixing and then granulating by adopting opposite roller extrusion at low temperature (60-65 DEG C), spraying slurry to encapsulate the granules by amino acid; and implanting a microbial agent to the encapsulation film according to 6-8 hundred million of bacteria per gram, wherein the microbial agent comprises plant growth promoting bacteria, bacilli and actinomycetes. The organic and inorganic compound fertilizer provided by the invention integrates organic fertilizer, the chemical fertilizer and microorganism into one and has advantages of strong fertility, durable fertilizer, high fertilizer utilization rate, capabilities of repairing and improving soil structure, enriching organic substances of soil, improving crop quality and increasing output and the like.

Description

technical field [0001] The invention relates to an organic-inorganic compound fertilizer. Background technique [0002] At present, the application of organic and inorganic compound fertilizers is becoming more and more common. However, the organic-inorganic 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 object of the present invention is to overcome the above disadvantages and provide an organic-inorganic compound fertilizer, which is convenient for crops to absorb nutrients and can ...
