Embodiment 1

[0030] A pearl oyster culture natural pearl method, comprising the following steps:

[0031] 1. Prepare shell powder.

[0032] Take shells, process them into nanoscale shell powder (particle size: 50nm), sterilize, and add sterilized and filtered seawater according to the amount of 10g shell powder and 100ml seawater, stir to make shell powder paste, and set aside;

[0033] 2. Prepare pearl oysters.

[0034] Take the pearl oyster, wash it, and place the oyster mouth down for a period of time to let the water and impurities in the oyster flow out of the body to make the oyster meat clean. After anesthesia with drugs, the oyster mouth is fully opened and the oyster is ready for injection.

[0035] Three, injection.

[0036] Then use a syringe to inject a small amount of (about one drop, 0.05ml) shell powder paste into the middle of the designated thin edge membrane on both sides of the most curved part of the shell junction of the pearl oyster body edge membrane (such as figu...

Embodiment 2

[0044] A method for cultivating natural pearls from pearl oysters, which is basically the same as the method in Example 1, the only difference being that the cultured pearl oysters in this embodiment are white butterfly pearl oysters, the particle diameter of the shell powder is 90nm, the cultivation time is 1 year, and the survival rate is 60% %, the particle size of the resulting tiny pearls is 1-2mm.

Abstract

The invention relates to a method for breeding natural pearls through pearl oysters and obtained pearls, and belongs to the technical field of pearl breeding. The method includes the following steps that shells are taken and processed into nanometer shell powder, the nanometer shell powder is sterilized, sterilized and filtered seawater is added into the nanometer shell powder, and shell powder paste is prepared for usage; the pearl oysters are taken, oyster openings of the pearl oysters are formed downwards so that water and impurities in pearl oyster bodies can flow out of the pearl oysters,and through medicine anesthesia, all the oyster openings of the pearl oysters can be open for usage; an appropriate amount of shell powder paste is injected into vela of the pearl oyster bodies and the shells; the oyster openings of the pearl oysters into which the shell powder paste is injected are upward, standing is performed, then the pearl oysters are placed into seawater for breeding, and the pearls can be collected after the pearls grow up. According to the method for breeding the natural pearls through the pearl oysters, cell tab transplanting is not needed, substances containing calcium carbonate are directly injected into the vela, and nacre are formed by the utilization of the vela of the oyster bodies. According to the method for breeding the pearls, investment is small, benefits are high, the dead rate during breeding of the oysters is small, and return is large.

Description

technical field [0001] The invention relates to the technical field of pearl cultivation, in particular to a pearl oyster cultivation method for natural pearls and the obtained pearls. Background technique [0002] There are two traditional methods of artificially cultivating pearls using pearl oysters: the first method is to artificially cut the cell membranes of the same type of pearl oysters into small pieces and insert them into the organs of other live oysters that do not affect life to form pearls. It is called cell beads, which are pearls without nuclei; the second type of artificial cultured pearls is often called free pearls. The culture method is to use sand grains containing calcium carbonate, usually shells, to grind into a round nuclei as the bead nucleus. The nucleus is inserted into the position of the organ that does not affect the life of the pearl oyster, and a small piece of the same pearl oyster cell is transplanted and adhered to the surface of the pearl...
