Description

Technical Field

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

[0002] The long-term and large-scale use of traditional chemical fertilizers will not only lead to soil degradation problems such as soil acidification and salinization, but also pollute water and air, thus affecting the sustainable development of the ecological environment. Therefore, the development and application of green and environmentally friendly biofertilizers has become an important direction for the sustainable development of agriculture.

[0003] Biofertilizer is a type of fertilizer with microorganisms or their metabolites as the main ingredients. It can promote the increase of beneficial microorganisms in the soil, improve soil structure, and increase soil fertility through the growth, reproduction and metabolic activities of microorganisms, thereby promoting the healthy growth of crops. Compared with chemical fertilizers, biofertilizers have the advantages of not polluting the environment, not destroying soil structure, and improving crop quality.

[0004] Tea seed meal is a byproduct of oil extraction from camellia seeds. It is rich in bioactive substances such as tea saponin, tea seed polysaccharides, and tea protein. Tea saponin has good antibacterial, antiviral, and antioxidant biological activities, and can enhance the disease resistance of crops. Tea seed polysaccharides and tea protein can serve as carbon and nitrogen sources for microorganisms, promoting their growth and reproduction. However, the direct application of tea seed meal has certain limitations, such as its macromolecular substances are difficult to be directly absorbed by crops, and are easily affected by environmental factors, which reduces the fertilizer efficiency.

[0005] At present, there are many methods for preparing biofertilizers on the market, but the following problems are common: first, the preparation process is complicated and the cost is high, which is not conducive to large-scale production and promotion and application; second, the fertilizer effect is unstable and is greatly affected by factors such as soil environment and climatic conditions; third, the ingredients are relatively simple and it is difficult to meet the needs of crops for multiple nutrients at different growth stages. Therefore, it is of great practical significance and broad application prospects to develop a biofertilizer with simple preparation process, low cost, stable fertilizer effect and comprehensive nutrition.

[0006] The present invention aims to prepare a tea seed meal extract enhanced biofertilizer by utilizing the effective ingredients in tea seed meal and combining multiple ingredients such as composite microbial agents, organic fertilizer matrix, trace elements and slow-release nitrogen sources. The fertilizer can not only enhance the disease resistance of crops and improve soil structure, but also provide comprehensive nutritional elements to meet the growth needs of crops, thereby effectively improving the yield and quality of crops.
