Description

Technical Field

[0001] The invention relates to the technical field of fertilizer preparation, in particular to a biological organic fertilizer using tobacco powder as a carrier and supplemented with deep-sea enzymatically hydrolyzed fish protein and a preparation method thereof. Background Art

[0002] The rapid development of livestock and poultry farming in my country has significantly improved the agricultural economic level, but has also produced a large amount of livestock and poultry manure, which has become one of the sources of agricultural pollution. At present, the production of green and efficient organic fertilizer from livestock and poultry manure through aerobic composting and application to the soil is an important link in the organic combination of livestock and poultry farming and ecological agriculture. However, organic fertilizer products have a series of problems such as low fertilizer efficiency, slow effect, and difficulty in promotion, which seriously restrict the application of organic fertilizers.

[0003] At the same time, in order to solve the problems of organic fertilizer utilization rate and ecological environment pollution, many scientific research institutions at home and abroad have developed corresponding organic compound fertilizers with slow-release functions and compound microbial fertilizers according to local conditions, the growth laws and fertilizer requirements of different crops, and have achieved good social, economic and ecological benefits through promotion and application. It has shown relatively ideal results in the long-term effectiveness of fertilizers, improvement of fertilizer utilization rate, soil loosening, soil fertility improvement, prevention of soil-borne diseases and insect pests, and improvement of fruit quality and yield. Especially in the case of the gradual reduction of rural labor force, the labor-saving and labor-saving "base fertilizer one-step clearing" fertilization is deeply welcomed by farmers.

[0004] However, the results show that the release of inorganic nutrients in bio-organic fertilizers is closely related to the type, quantity, fineness of organic materials and the degree of adsorption of inorganic nutrients by organic matter after dissolution during the production process. The greater the specific gravity of organic materials, the higher the content, the finer the fineness and the more inorganic nutrients adsorbed by organic matter, the slower the fertilizer disintegration speed, the longer the delay time of nutrient release, and the fertilizer effect has an obvious slow-release effect. On the contrary, the rapidity of its fertilizers is getting worse and worse. Therefore, the poor rapidity of nutrients in organic fertilizers and compound microbial fertilizers seriously restricts their development and affects the use effect. However, the slow-release characteristics of bio-organic fertilizers play an important role in reducing the amount and loss of chemical fertilizers, slowing down the release rate of inorganic nutrients in fertilizers and delaying the release time of nutrients, and reducing the amount of labor used in topdressing in crop cultivation. How to improve the utilization rate of bio-organic fertilizer products, prevent or inhibit a variety of soil-borne diseases, increase yields, improve quality, and accelerate the pace of bio-organic fertilizers replacing chemical fertilizers are issues that need to be urgently addressed. Summary of the invention

[0005] The present invention aims to solve the deficiencies in the prior art and provide a biological organic fertilizer using tobacco powder as a carrier and supplemented with deep-sea enzymatically hydrolyzed fish protein and a preparation method thereof.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] The present invention provides a biological organic fertilizer using tobacco powder as a carrier and supplemented with deep-sea enzymatically hydrolyzed fish protein, which is calculated by weight:

[0008] 35-45 parts of organic fertilizer, 6-15 parts of composite microorganisms, 5-10 parts of medium element fertilizer, 1-2 parts of trace element fertilizer, 0.1-1 parts of xanthan gum and sulfur suspension, 30-35 parts of outer layer fertilizer, 0.1-0.5 parts of anti-caking agent; the organic fertilizer is tobacco powder, meat meal, bone meal, deep-sea enzymatic fish protein.

[0012] Preferably, the anti-caking agent is an alkylamine acetate cationic surfactant.

[0013] The present invention adopts pure natural organic raw material (tobacco powder) as a carrier because tobacco powder is rich in organic matter and multiple nutrients, such as organic carbon, total nitrogen, total phosphorus and potassium elements, etc. These components can improve the fertility and water content of soil, improve soil structure, and increase the water retention capacity and fertility of soil; the nitrogen, phosphorus, potassium and other nutrient elements in tobacco powder can be directly absorbed and utilized by plants to promote the growth and development of crops; tobacco powder will produce organic acids and other substances during the composting process, change the physical properties of soil, increase soil porosity, enhance air permeability and water retention, and thus improve soil structure; tobacco powder contains rich microbial species and quantities, which can increase the number of beneficial microorganisms in soil, promote the ecological balance of soil, and reduce the occurrence of soil diseases and insect pests; certain components in tobacco powder, such as nicotine and nicotine, have a certain killing effect on underground pests, enhance the disease resistance of plants, and improve the yield and quality of crops.

[0014] The biological organic fertilizer provided by the present invention also includes meat meal, bone meal, and deep-sea enzymatic fish protein. Meat meal is rich in crude protein, organic nitrogen, phosphorus, potassium and other elements, which are essential for the growth and development of crops. The crude protein in meat meal not only contains rich nitrogen, but also contains other essential amino acids and other nutrients, which can provide the required nutrients for crops and promote the healthy growth of crops. Bone meal is rich in phosphorus, calcium, magnesium, iron and other nutrients, which are essential for plant growth. Phosphorus is an important element that promotes plant root development, flower bud differentiation, fruit ripening and other processes; calcium helps the formation and maintenance of plant cell walls and enhances the plant's ability to resist diseases and pests. Deep-sea enzymatic fish protein Fish protein is rich in organic matter and a variety of trace elements. After being applied to the soil, it can be quickly utilized by beneficial microorganisms, promote microbial reproduction, optimize soil structure, and improve the soil's ability to retain fertilizer and water. It is rich in nutrients such as polypeptides, oligopeptides, and free amino acids, which can regulate and balance the growth and development of plants, promote the balanced absorption of required nutrients by crops, and enhance the efficiency of photosynthesis. Its nutrients can increase the content of unsaturated fatty acids and proline in crop membrane lipids, stabilize membrane structure, and improve the cold resistance of crops. It performs well in activating the soil and improving the soil's ability to retain fertilizer and water, which helps prevent the loss of nutrients and improve the utilization rate of fertilizers by plants.

[0015] The present invention selects Bacillus licheniformis, Paenibacillus gelatinus, Bacillus subtilis, and Bacillus amyloliquefaciens, ferments them separately, and prepares high-purity, high-count bacterial powder raw materials by spraying powder, while retaining a variety of effective metabolites in the fermentation liquid. After being applied to the soil, the functional microorganisms multiply and grow in large quantities, which can improve the number and structure of rhizosphere soil microbial communities, increase the soil microbial biomass, and improve the diversity of soil microorganisms; form dominant bacterial communities in the rhizosphere of crops, thereby inhibiting the growth and reproduction of other harmful microorganisms, producing antagonistic effects on harmful pathogens, and reducing the occurrence of diseases; functional microorganisms can induce crops to produce peroxidase, polyphenol oxidase, glucanase, etc. to participate in the plant's defense response to harmful microorganisms, and improve the adaptability of crops to adverse environments.

[0016] The present invention stabilizes the cell membrane structure of crops, stimulates cell elongation, accelerates root growth and development, enhances crop photosynthesis, activates key enzymes of physiological metabolism in crops, and promotes the growth and development of crops by adding secondary elements.

[0017] The present invention stabilizes the normal physiological metabolic function of plants by adding trace elements, promotes the growth and development of plants, and avoids problems such as poor growth and development, reduced production, and reduced quality caused by nutrient deficiency in the late growth period of plants.

[0018] The present invention adds raw materials with quick-acting and slow-release nutrition engineering during the preparation process, and sprays xanthan gum and sulfur suspension, outer fertilizer, and anti-caking agent, so as to achieve instant fertility replenishment, enable crops to continuously absorb rich organic nutrients, and form a hydrophobic film on the surface of fertilizer particles to prevent the surface of the particles from absorbing moisture, dissolving and recrystallizing, thereby improving the agglomeration property of the fertilizer.
