preparation example Construction

[0032] The preparation method of the above-mentioned tissue extract of the donor body is as follows: the outer mantle fluid of the donor body is extracted by a syringe, that is, a thin layer of translucent fluid-like substance exists between the mantle and the shell, and the outer mantle fluid is in the Here it is used as a dissolving carrier (i.e. solvent) for polyvinylpyrrolidone, calcium gluconate or cobalt chloride.

[0033] Step 3. Rehabilitation: put the pearl oysters after the operation into a clean seawater site for recuperation, and regularly disinfect the wound; 20 to 30 days after the operation, transfer the pearl oysters after the operation to a marine culture area rich in food , after 1 to 2 years of cultivation, colorful seawater pearls can be obtained.

[0034] The above-mentioned seawater site refers to clean seawater that has not been fed with any feed, nor has Pinctada martensii been cultured; the above-mentioned seawater culture area refers to seawater that ...

Embodiment 1

[0040]The cultivation method of the colorful seawater pearl of the present embodiment comprises the following steps:

[0041] (1) Film production: choose Panda abalone as the donor body, which is required to be intact, physiologically healthy, aged 1 year, and body length 3cm; take the mantle of the donor body, remove the color line, and then perform purification and disinfection treatment: first use Rinse the mantle with deionized water for 4 times, then soak with 5% iodophor in seawater solution for 1 min;

[0042] Then tear off the outer skin of the attached shell and cut it into small pieces with a size of 2mm×2mm. The above process of tearing and slicing is completed within 3 minutes.

[0043] (2) Operation: Select Pinctada martensii as the pearl oyster, which requires intact, healthy physiology, underdeveloped gonads, 2 years old, and 9 cm in body length; insert the shell opener into the gap of the pearl oyster, and then fix it with a plug. Use an open knife to incise 3...

Embodiment 2

[0047] The cultivation method of the colorful seawater pearl of the present embodiment comprises the following steps:

[0048] (1) Film production: choose Emerald mussels as the donor body, which is required to be intact, physiologically healthy, 1.5 years old, and 7cm in length; take the mantle of the donor body, remove the color line, and then perform purification and disinfection treatment: first use Rinse the mantle with deionized water for 4 times, then soak with 5% iodophor in seawater solution for 1 min;

[0049] Then tear off the outer skin of the attached shell and cut it into small pieces with a size of 3 mm × 3 mm. The above process of tearing and slicing is completed within 4 minutes.

[0050] (2) Operation: Select Pinctada martensii as the pearl oyster, which requires intact, healthy physiology, underdeveloped gonads, 2 years old, and 9 cm in body length; insert the shell opener into the gap of the pearl oyster, and then fix it with a plug. Use an open knife to i...

Abstract

The invention belongs to the pearl cultivation field, and particularly relates to a cultivation method of colorful seawater pearls. The cultivation method of the colorful seawater pearls includes: implanting small slices formed by cutting palliums of abalones or mussels in gonad of pinctada martensii; then, tightly attaching pearl nuclei to the small slices so as to implant the pearl nuclei; cultivating the pinctada martensii in seawater after recuperation so as to obtain the colorful seawater pearls. The cultivation method of the colorful seawater pearls uses the characteristic of being bright in nacre color of the abalones or the mussels, uses the abalones or the mussels to produce the pearls for slice bodies of the small slices, can obtain the seawater pearls having colorful effects, can improve survival rate and pearl obtaining rate of the pearly shellfish and production rate of high quality pearls through synergistic action of appropriate operation steps and parameters, and is simple in operation process and convenient to use widely.

Description

technical field [0001] The invention belongs to the field of pearl cultivation, and in particular relates to a method for cultivating colorful seawater pearls. In the method, small pieces cut from the mantle of abalone or mussel are implanted into the gonads of Pinctada martensii, and then the small pieces are planted tightly. The pearl nucleus is put into the seawater culture after recuperation, and colorful seawater pearls are cultivated. Background technique [0002] Pearls are the product of biomineralization in molluscs. They are precious organic jewels. They are generally divided into seawater pearls and freshwater pearls. Seawater pearls are mainly produced in pearl oysters, white butterfly shells, and black butterfly shells. The shape, size, and luster are better than freshwater pearls. Most of them are perfectly round, and the grains are shining, beautiful and elegant. It has always been believed in the world that "the western pearl is not as good as the eastern pea...
