Special bio-organic fertilizer for beta vulgaris and preparation method of bio-organic fertilizer

Abstract

The invention discloses a special bio-organic fertilizer for beta vulgaris and a preparation method of the bio-organic fertilizer. The special bio-organic fertilizer for the beta vulgaris comprises the following components, in parts by mass: 25-30 parts of beta vulgaris tail roots, 25-35 parts of a sugar refinery residue mixture, 20-30 parts of cow and sheep dung, 3-5 parts of an activation biological fermentation liquid, 3-5 parts of a synergist, 8-10 parts of a yeast urea sulfate concentrate, and 0.2-0.5 part of concentrated bacterial powder. The preparation method comprises the following steps: (1) performing mixing under stirring; (2) performing fermentation culture; (3) performing aging decomposition; (4) performing drying; (5) performing granulation; and (6) performing coating. The method provided by the invention has the beneficial effects of realizing comprehensive utilization of the beta vulgaris tail roots, the sugar refinery residue and the yeast concentrate in a sugar refinery, solving the difficult problem of treatment of the three major waste, avoiding pollution to the environment by the three major waste, effectively utilizing multiple nutrient elements contained inthe three major waste, and forming the special bio-organic fertilizer capable of ameliorating soil, improving the sugar content of the beta vulgaris and increasing the yield of the beta vulgaris for the beta vulgaris.

[0004] Beet is the main source of sugar except sugarcane. Beet tail and sugar filter sludge are the main wastes of sugar beet sugar enterprises at present; The tail root and the attached soil of the beet are generally 0.5% of the total weight of the beet, and about 50 tons of waste beet tail root are produced by processing 10,000 tons of beet raw materials; %, the pH value is about 6.4, and it also contains other beneficial nutritional elements; at present, the treatment of beet tail roots is generally carried out by digging trenches and filling them or directly returning them to the field without any treatment. If the pathogenic bacteria carried on the beet tail roots are directly returned to the field Invade crops again and increase the chance of crop disease; at the same time, because the beet tail root contains a large amount of organic matter, due to poor ventilation and the action of microorganisms during the accumulation process, it is very easy to deteriorate and smell, pollute the air, and affect environmental sanitation

[0005] Sugar filter sludge is a by-product of sugar beet in the process of sugar production, using lime and carbon dioxide as clarifying agents to clarify sugar juice, and it is also a bulk waste of sugar beet sugar enterprises. According to calculations, 10,000 tons of sugar beet is used as raw material About 5,000 tons of sugar filter sludge waste should be discharged; the main components of sugar filter sludge include organic matter, various minerals and medium and trace elements, etc., of which the pH value is about 9.8, the water content is 27.5%, and the organic matter content is ≥ 5.5%. Nutrients ≥ 5%, medium and trace elements are mainly calcium, and there are also various medium and trace elements such as magnesium, iron, manganese, copper, zinc, etc. Currently, the treatment of sugar filter sludge is generally carried out by digging trenches for landfill or directly returning to the field , the way of digging and filling not only takes up a lot of land, but also the cost of machinery and transportation for digging and filling are high. In addition, because it contains a variety of organic and sugar substances, it is easy to mold, smell, and breed flies. , pollute the air, affect the soil environment, and its leachate will also pollute the groundwater; at the same time, due to its high pH value, it will aggravate the alkalinity of the soil after returning to the field, hinder the growth of crops, and even cause the crops to fail to grow

[0006] Sugar beet sugar enterprises produce a large amount of molasses every year. The molasses contains a large amount of natural plant polysaccharides, monosaccharides, potassium, and trace elements. It is the raw material for the production of dry yeast powder or yeast extract and other products. It is the waste liquid after yeast fermentation and transformation. After testing, the yeast concentrated liquid has a pH value of about 6.5, organic matter content ≥ 20%, total nutrient ≥ 8%, brix ≥ 47%, betaine ≥ 6%, dry matter It is about 47%, and contains a variety of mineral nutrients that are beneficial to the growth of beet, such as sodium ions and magnesium ions. It is a high-quality nutrient liquid; Sewage discharge or direct farmland irrigation, due to the high COD value of the yeast concentrate, that is, the high content of organic matter, salts, etc., directly discharging the yeast concentrate with the sewage will cause eutrophication of the water body, making the water hypoxic and water quality Deterioration, extinction of fish and shrimp, stink of river water, pollution of drinking water sources, affecting human health; if the yeast concentrate is directly used for farmland irrigation, the concentration of organic matter, salts and other substances in the yeast concentrate will be higher than that in crops, In turn, it will cause the water in the crop cells to reverse osmosis from the crops to the soil through the cell membrane, causing the crops to wither or even "burn to death"

[0007] Sugar beet is a crop that requires more fertilizer and nutrients. During the growth process, it is necessary to apply fertilizers according to the needs of beet for nutrients. Although there are many types of fertilizers on the market, there is a lack of fertilizers based on the needs of beet growth. Special fertilizers produced by formula, such as blind fertilization by farmers, will not only reduce the yield and content of sugar beet, but also aggravate the disease of sugar beet cropping, which will affect the economic benefits of beet sugar enterprises and farmers
