Description

Technical Field

[0001] The invention belongs to the technical field of fertilizers, and in particular relates to a novel tea dregs extract composite biological organic fertilizer and a preparation method thereof. Background Art

[0002] With the development of modern agriculture, the limitations of traditional fertilizers have gradually become apparent. Due to their single nutrient supply and rapid release characteristics, they often lead to low fertilizer utilization and serious nutrient loss, which in turn causes soil and water pollution problems. Long-term reliance on traditional fertilizers may also destroy soil structure, reduce soil microbial diversity, and affect the long-term fertility of the soil and the healthy growth of crops. In addition, traditional fertilizers do not directly enhance the resistance of crops to pests, making pest control a major challenge in agricultural production and requiring additional application of pesticides, which not only increases production costs but also creates additional pressure on the environment. In view of the above limitations of traditional fertilizers, the development of new fertilizers has become an inevitable choice for the green and sustainable development of agriculture.

[0003] Tea seed meal extract is rich in tea saponin, tea seed polysaccharide and tea protein, and has a wide range of application potential. Tea saponin, as a natural non-ionic surfactant, not only has insecticidal and antibacterial effects, but also can improve the disease resistance of crops. Tea seed polysaccharide and tea protein provide crops with essential organic nutrition, promote growth and increase yield.

[0004] Microbial agents, such as Bacillus licheniformis, Bacillus thuringiensis and Bacillus laterosporus, have been proven to effectively improve the quality of agricultural products, enhance crop resistance, and increase fertilizer utilization. They secrete antibiotic substances and active enzymes to inhibit pathogenic bacteria and reduce the occurrence of diseases. At the same time, they promote the dissolution and release of insoluble nutrients in the soil and improve the soil's nutrient supply capacity.

[0005] Amino acids, such as alanine, arginine and aspartic acid, and seaweed extracts, including fucoidan, fucoidan, alginate and mannitol, all have the function of biostimulants. They can regulate the metabolism and physiological functions of crops, promote root growth, increase biomass, improve crop yields, and alleviate pests and diseases and prevent abiotic stresses such as frost damage and drought.

[0006] Humic acid, derived from soil or coal, is a polycondensate of polyvalent phenolic aromatic compounds and nitrogen compounds, rich in a variety of active functional groups. It can improve soil structure, increase soil aeration and water retention, and is beneficial to the growth of plant roots. Humic acid can also complex a variety of trace elements, providing plants with stable chelated mineral elements that are quickly absorbed and utilized by plants.

[0007] Therefore, the development of new tea seed meal extract composite bio-organic fertilizer is of great significance for improving soil environment, enhancing crop resistance to insects and increasing crop yield. Summary of the invention

[0008] The invention specifically relates to a novel tea dregs extract composite biological organic fertilizer and a preparation method thereof. The composite biological organic fertilizer can not only improve the soil environment, but also increase the insect resistance and yield of crops.

[0009] To achieve the above object, the present invention provides the following technical solutions:

[0010] The first aspect of the present invention is to provide a novel tea meal extract composite biological organic fertilizer, comprising the following components: 50-70 parts of tea meal extract, 5-15 parts of microbial agents, 10-20 parts of amino acids, 5-15 parts of seaweed extract, 1-5 parts of trace elements, and 5-10 parts of humic acid.

[0011] As a further technical solution, the tea dregs extract is tea saponin, tea seed polysaccharide and tea protein.

[0012] As a further technical solution, the microbial agent is any one or more of Bacillus licheniformis, Bacillus thuringiensis, and Bacillus laterosporus.

[0013] As a further technical solution, the amino acids are alanine, arginine, and aspartic acid.

[0014] As a further technical solution, the seaweed extract is any one or more of fucoidan, fucoidan, alginate, and mannitol.

[0015] As a further technical solution, the trace elements are iron, manganese, zinc and copper.

[0016] As a further technical solution, the humic acid is any one or more of soil humic acid and coal humic acid.

[0017] The second aspect of the present invention is to provide a method for preparing a novel tea seed meal extract composite bio-organic fertilizer, comprising the following steps:

[0018] (1) crushing the tea seed meal extract to a particle size of less than 100 mesh;

[0019] (2) mixing the crushed tea seed meal extract with a microbial agent, adjusting the moisture content to 40-50%, and fermenting the mixture at a temperature of 55-60° C. for 10-14 days, with the fermentation pile turned every 4-7 days;

[0020] (3) uniformly mixing the amino acid and the seaweed extract to form an amino acid seaweed complex;

[0021] (4) adding trace elements in a chelated state or a salt state to the amino acid seaweed complex to form a trace element complex;

[0022] (5) crushing and sieving the humic acid to obtain a crushed material with a particle size of 30 to 100 meshes;

[0023] (6) mixing the fermented tea seed meal extract, the trace element complex, and the humic acid uniformly;

[0024] (7) granulating the mixture to a particle size of 2-5 mm, and then drying the mixture to a moisture content of less than 10%;

[0025] (8) The dried fertilizer is packaged to obtain a novel tea seed meal extract composite bio-organic fertilizer.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. Improve soil environment: The addition of humic acid can optimize soil structure, improve soil permeability and water retention capacity, and thus promote the development of plant roots. In addition, microbial agents actively participate in nutrient circulation through vigorous life activities. While reproducing, they can improve soil compaction and have the effect of fertilizing the land and improving the soil.

[0028] 2. Improve crop resistance to insects: Tea saponins and microbial agents can produce antagonistic effects and reduce the damage of pests and diseases to crops. Tea saponins, as a natural non-ionic surfactant, have the dual effects of insecticide and antibacterial, which can improve the disease resistance of crops. At the same time, microbial agents can effectively inhibit the growth of pathogens, reduce the frequency of diseases, and enhance the natural defense mechanism of crops by producing antibiotic substances and active enzymes.

[0029] 3. Increase crop yields: Tea seed polysaccharides and tea proteins provide key organic nutrients for plant growth, which helps promote plant growth and increase yields. Specific amino acids and seaweed extracts, as biostimulants, regulate plant metabolic activities and physiological processes, stimulate root development and biomass accumulation, and thus increase crop yields. At the same time, humic acid provides plants with easily absorbed mineral forms by chelating a variety of essential micronutrients, further improving crop growth efficiency and yields.
