Example Embodiment

[0022] Example 1 (Tea residue fermentation to produce special organic fertilizer for tea gardens): The fermented actinomycete strains were evenly added to the tea residue, and the temperature was 35~50℃ and the water content was 55% in the tea residue environment. Aerobic treatment for three days each, in which the tea residues need to be regularly turned every 24 hours during aerobic fermentation; the fermented tea residue fertilizer is dried at 60°C for 4.5 hours, granulated with a granulator, and the granulated tea residues are measured The organic matter of the fertilizer product is 37.2%, the total amount of available nitrogen, phosphorus, and potassium is 5.5%, the water content is 12%, and the appearance of the product is brown particles.

Example Embodiment

[0023] Example 2 (Tea residue fermentation to produce special organic fertilizer for tea gardens): The fermented mold strains are evenly added to the tea residue, and the temperature is 35~50℃ and the water content is 65% in the tea residue environment anaerobic and aerobic Treated for three days each. During aerobic fermentation, the tea residues need to be turned regularly every 24 hours; the fermented tea residue fertilizer is dried at 60°C for 5.0 hours, granulated with a granulator, and the granulated tea residue fertilizer product is measured The organic matter is 36.0%, the total amount of available nitrogen, phosphorus, and potassium is 6.3%, the water content is 13%, and the appearance of the product is brown particles.

Example Embodiment

[0024] Example 3 (Tea residue fermentation to produce special organic fertilizer for tea gardens): The fermented actinomycete strains were evenly added to the tea residue, and the temperature was 35~50℃ and the water content was 50% in the tea residue environment. Aerobic treatment for three days each, in which the tea residues need to be turned regularly every 24 hours during aerobic fermentation; the fermented tea residue fertilizer is dried at 60°C for 3.0 hours, granulated with a granulator, and the granulated tea residues are measured The organic matter of the fertilizer product is 35.5%, the total amount of available nitrogen, phosphorus, and potassium is 5.9%, the water content is 13%, and the appearance of the product is brown particles.

Abstract

The residue is produced into organic fertilizer or organic-inorganic composite fertilizer specially for tea garden through the process of microbial fermentation, anaerobic and aerobic fermentation, drying, and pelletizing. When it is applied in tea garden, amino acid and other macro molecular matters are absorbed directly by tea tree, and the tea polyphenol can inhibit the activity of the urease to raise the utilization of inorganic nitrogen fertilizer.

Description

technical field [0001] The invention relates to the manufacture of fertilizer, which is a method for fermenting tea dregs to produce special fertilizer for tea gardens. Background technique [0002] Since the output of tea beverages in my country has increased exponentially in recent years, the annual production of tea dregs has reached more than 100,000 tons. In addition to the tea waste produced by tea beverage manufacturers, dozens of other tea polyphenol manufacturers are also facing this problem. Most of these tea residues are treated as urban waste and are paid by the manufacturers to be handed over to the environmental protection department for disposal. Natural stacking will cause serious environmental pollution and a huge waste of resources. [0003] The protein content in the tea dregs is relatively high, the crude protein content is as high as 18%-20%, the amino acid composition is relatively reasonable, the lysine and methionine content...
