Micro-nano organic fertilizer

Abstract

The invention belongs to the technical field of fertilizers with shapes as characteristics and in particular relates to a micro-nano water-soluble organic fertilizer of which the particle size is 80nmto 20[mu] m. The organic fertilizer is high in absorption rate by plant cells, outstanding in fertilizer effect and capable of increasing yields, improving effects, reducing cost and improving quality. The organic fertilizer is high in solid content, does not burn seedlings, in addition is remarkable in fertilizer effect, is free of chemical residue, and is capable of reducing the rate of insects, the lodging rate and the seedling burning rate, improving soil environments, improving the fertilizer effect and inhibiting growth of weeds. The organic fertilizer is free of emission of "three wastes" in the production process, is small in floor space and short in production cycle, is not limited by seasons and can be produced all over the year, the production cost can be greatly reduced, and the yield of the organic fertilizer is high.

Description

technical field [0001] The invention belongs to the technical field of fertilizers characterized by shapes, and in particular relates to a micro-nano organic fertilizer. Background technique [0002] With the improvement of living standards and the change of dietary structure, the proportion of livestock and poultry products in the dietary structure is gradually increasing. Therefore, the breeding industry has also developed rapidly. The rapid development of the large-scale breeding industry has brought serious environmental pollution problems while meeting the needs of human beings for meat, eggs and milk. A large amount of livestock and poultry manure pollutants are discharged into the natural environment at will, which has brought huge pressure to the ecological environment and seriously polluted the water, soil and atmosphere. Therefore, the reduction, harmless and resourceful treatment of livestock and poultry manure to prevent and eliminate the pollution of livestock ...

AI Technical Summary

Problems solved by technology

Among them, high-temperature composting has the advantages of short time consumption, less odor, sufficient decomposition of organic matter, relatively dry, easy packaging, and can be made into organic fertilizers. However, composting generally has the following five problems: (1) Fermentation is not standardized

The correct method for the treatment of organic waste mainly composed of feces should be: high-temperature fermentation, medium-temperature fermentation, low-temperature fermentation, alcoholization and drying. , discharge and reduce harmful gases, decompose harmful substances, and activate various nutrients. At present, more than 80% of organic fertilizer factories cannot do this. Some factories pile up livestock, poultry, and human excrement naturally for a period of time before using them in farmland; Some factories pull back the livestock and poultry manure and mix it with some weeds, straw or coal dry stone powder, etc., and bury it for a period of time, crush it and then pack it into bags for sale, which not only has poor fertilizer efficiency, but also causes secondary pollution; (2) the particles are large, low absorption rate

Most (more than 95%) organic fertilizer factories produce organic fertilizers with large particles (small 1-3 mm, large 3-5 mm, or even larger particle size), low absorption rate (absorption rate is less than 20%), and some The effect of applying fertilizer to 800-1000kg per mu of land is not obvious; (3) Low solid content: some organic water-soluble fertilizer factories blindly pursue small particles, and use high-pressure homogeneous extraction of organic fertilizer, the concentration is too high to enter 1-3 mm The homogeneous machine hole can only pass through by increasing the amount of water and diluting the concentration. As a result, the solid content of the water-soluble organic fertilizer produced is less than 10%, and the fertilizer efficiency is poor; (4) There are chemical residues in the production process

In order to pursue the small particle size of the fertilizer, some companies use "chemical cracking" (burning with alkali first, then neutralizing with acid) to reduce the material, and then extract it with a high-pressure homogenizer, which inevitably produces chemical residues. Burn leaves and roots on crops, causing user disputes; (5) Take the "petrochemical agricultural route"

Some companies process phosphate rock, potassium ore, and nitrogen elements into nano-fertilizers, and some companies use waste plastic bags and other materials to produce nano-coated fertilizers. This is not conducive to solving the problems of soil acidification, deterioration, and compaction in our country, let alone It is in line with the current policy of "reducing chemical fertilizers" in China and the general trend of organic agriculture in the world
