Preparation method of pure natural efficient pond clearing tea meal solution

Abstract

The invention discloses a preparation method of a pure natural efficient pond clearing tea meal solution and relates to the technical field of aquaculture. The preparation method mainly comprises thefollowing steps: 1) cleaning; 2) impregnation: adding water 6-8 times as much as the total weight into cleaned tea meal and tea seed shells to be impregnated for 12 h to obtain an impregnated product;3) decocting and filtering: carrying out first decoction on the impregnated product, finishing the first decoction, and then, carrying out filtration while being hot to obtain a decoction and filterresidues; adding water into the filter residues, then, carrying out secondary decoction, finishing the secondary decoction, then, carrying out filtration while being hot to obtain a decoction and filter residues; 4) decoction mixing and filtering: mixing the decoction obtained by first decoction with the decoction obtained by secondary decoction, carrying out uniform stirring, and then, sieving the mixture by using a 100-mesh sieve to obtain a filtrate; and 5) concentration: precipitating the filtrate for 12 h, then, extracting a supernatant, and carrying out concentration until the weight accounts for 2% of the original weight. Tea saponin is effectively extracted by deeply processing the tea meal and the tea seed shells so as to be favorably used on a large area and high in drug effect exertion speed, environment-friendly and safe.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for preparing a pure natural and high-efficiency clear pond tea dregs solution. Background technique [0002] Tea saponin, also known as tea saponin, is a kind of glycoside compound extracted from tea tree seeds (tea seeds, tea seeds). Tea saponin is a hemolytic toxin that can dissolve red blood cells of fish and can be used in aquaculture , mainly for the killing of wild fish, snails, loach, eels and some aquatic insects in aquatic ponds; tea saponin is environmentally friendly, non-toxic, and quick and convenient to use. It is a substitute for pesticides and is worth studying. and promoted products. [0003] Tea leaves contain tea saponin, which can be used in the development of tea saponin products, but the existing utilization of tea leaves is in the form of rough processing, tea leaves are crushed and packaged for use; when tea leaves are used, the dosage Larg...

Problems solved by technology

[0003] Tea leaves contain tea saponin, which can be used in the development of tea saponin products, but the existing utilization of tea leaves is in the form of rough processing, tea leaves are crushed and packaged for use; when tea leaves are used, the dosage Large, it is easy to cause excessive microorganisms in the water body, which will have an adverse effect on the water quality of fish ponds, and is not suitable for large-scale use; moreover, rough processing of tea meal is not conducive to storage, and it is easy to deteriorate, which is not conducive to transportation and promotion
