Description

Technical Field

[0001] The present invention relates to the field of agricultural technologies, and in particular to a preparation process for a high-quality liquid fertilizer prepared from abamectin and vitamin B12 waste liquid. Background Art

[0002] Liquid fertilizer, as the name implies, is a kind of liquid fertilizer, which is a direct spraying on the leaf surface or root of plants after chelating and compounding various elements and organic matters with water, so that the plants can absorb it more quickly. Due to its advantages of quick solubility and uniformity, it is the preferred fertilizer for fertilization by irrigation equipment. Due to its ready-to-use property without stirring and dissolving, it is very suitable for automated fertilization. In countries where irrigation technology and automated fertilization are popularized, liquid fertilizers are widely used.

[0003] Liquid fertilizers are more comprehensive in nutrition than traditional chemical fertilizers. After crops are applied with them, they grow more evenly, the resistance to stress and diseases increases significantly, the growth is vigorous, the yield and quality of crops can be significantly improved, the soil micro-ecology can be improved, the soil can be activated to promote root growth and resist continuous cropping, and they have the characteristics of high content, safety and no pollution. They are one of the development trends in the future fertilizer field.

[0004] Abamectin waste liquid is a by-product produced by fermenting to produce abamectin. Abamectin waste liquid is the residue remaining after fermenting soybean dregs liquid, peanut dregs liquid, starch, vitamins, etc. to produce abamectin. The organic matter of the dehydrated substance of this waste liquid is more than 75%, the contents of N, P, and K reach more than 4%, and it contains 0.2 - 0.4% abamectin. The abamectin liquid medicine can be directly applied to the roots of crops such as vegetables, green onions, ginger, and garlic. It is both a high-quality organic fertilizer and can kill a variety of underground pests. Vitamin B12 waste liquid is the production wastewater of producing vitamin B12, which is rich in organic acids, proteins, polysaccharides and other decomposition products and is a high-quality raw material for producing fertilizers. However, there are few reports in the prior art on preparing liquid fertilizers from abamectin waste liquid and vitamin B12 waste liquid together.

[0005] For example, the Chinese invention patent with the authorization announcement number CN102040430B discloses a production method of a composite microbial fertilizer with insecticidal effects. This method includes the preparation of a liquid bacterial agent, granulating abamectin waste liquid with inorganic fertilizers to form granular organic fertilizers, and compounding the granular organic fertilizers with the liquid bacterial agent. When compounding, the bacterial agent is added in a weight ratio of 0.5 - 1.5% of the finished composite microbial fertilizer, and then it is air-dried or dried in the shade. This invention breaks new ground and divides the production method of the granular composite microbial fertilizer into two steps: granulating organic fertilizers and coating the organic fertilizer granules with bacterial agents, while maintaining a certain activity. The composite microbial fertilizer product has achieved a breakthrough from powder to granule, laying a foundation for its large-scale promotion. At the same time, it also provides a method for resource utilization of abamectin waste liquid. However, it does not combine vitamin B12 waste liquid to make a liquid fertilizer, does not have the advantages of liquid fertilizers, and its fertilizer efficiency still needs to be further improved.

[0006] It can be seen that developing a preparation process for high-quality liquid fertilizer prepared from avermectin and vitamin B12 waste liquid, which has good fertilizer efficiency, can effectively promote the growth of crops, and has a significant effect on preventing insect pests, meets the market demand, has broad market value and application prospects, and is of great significance for promoting the development of the field of harmless treatment of tylosin and tiamulin waste liquid.
