Golden yellow seawater pearl cultivation methodTechnical Field
The invention belongs to the technical field of seawater pearl cultivation, and particularly relates to a cultivation method of golden yellow seawater pearls.
Background
Pearls are precious jewelry that is biomineralized in molluscs and generally classified into seawater pearls and freshwater pearls. Compared with fresh water pearls, most seawater pearls have high roundness, strong luster and more delicate hand feeling, and have more appreciation and medicinal values. In the prior art, seawater pearl cultivation is mainly performed by nucleus insertion cultivation, pearl nuclei are implanted into shells such as Pinctada martensii dunker through an operation and then placed into a suitable cultivation environment, and pearl nuclei are wrapped by a pearl layer secreted by the Pinctada martensii dunker through natural cultivation to form pearls. At present, because the color of the pearl is closely related to the color of the shell of the pearl donor, the pearl produced by the Margaritifera pearl oyster through mariculture has single color, only one color is on a single bead, and the appearance is monotonous. In order to obtain multicolor effect commercially, the pearl nucleus dyeing or finished pearl dyeing can only be carried out, and the artificial color-adding effect is always achieved, so that the pursuit of people cannot be met.
Disclosure of Invention
The invention aims to provide a method for cultivating golden seawater pearls, which can cultivate golden seawater pearls.
In order to achieve the purpose, the invention provides the following technical scheme: a cultivation method of golden yellow seawater pearls is characterized in that: the method comprises the following steps: s1, selecting yellow pearl oyster with the shell inner layer, obtaining connective tissues in the center of the mantle of the pearl oyster, and cutting to obtain small cell pieces; s2, selecting a healthy mature nacre with yellow inner layer, implanting a pearl nucleus into the pearl nucleus site through surgery, and sending the cell slice obtained in the step S1 into the nucleus site and attaching the cell slice to the pearl nucleus; s3, placing a plurality of Pinctada martensii shells implanted with pearl nuclei and cell slices into a seawater pond for resting for 25-35 days; after the recuperation is finished, removing dead shellfish and cleaning attachments on the nacre, and continuously culturing according to a conventional method; s4, after 2-3 months of cultivation, removing dead shellfish and cleaning attachments on the nacre; s5, executing the step S4, repeating for 4-5 times, and finishing the cultivation process.
Further, in the step S3, after the pearl oyster is completely incubated, the pearl oyster with the attachments cleaned is firstly identified and screened by an X-ray machine, and then the pearl oyster with the nucleus is continuously cultured.
Further, the nacre is recuperated before the nucleus implanting operation, and the specific operation is as follows: and (5) hanging and culturing the nacre selected in the step (S2), doubling the number of the nacre in each hanging and culturing cage compared with the number of the nacre in the normal hanging and culturing, and continuing culturing for 8-12 days. Specifically, the water temperature of the culture seawater which is recuperated before the operation is kept at 16-27 ℃, and the dissolved oxygen is 6-10 mg/L.
Compared with the prior art, the invention has the following beneficial effects: by adopting the cultivation method, mantle cell pieces are obtained from the pearl shells with yellow inner surface layers of the shells, the pearl shells are transplanted into nucleus positions of the yellow pearl shells with yellow inner surface layers of the shells through cell transplantation and pearl nucleus transplantation, and during cultivation, the pearl shells are subjected to endocrine decomposition and melting to form pearl sacs and form golden pearl shells, so that golden pearls are produced.
Whether the nucleuses are left after the recuperation is further distinguished through an X-ray machine, the seedless nacre can be re-seeded and then cultured continuously, the pearl production rate is improved, and the culture cost is reduced.

Detailed Description
In order to make those skilled in the art understand the technical solutions of the present invention well, the following description of the present invention is provided with reference to the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.
As shown in figure 1, the cultivation method of the golden yellow seawater pearl comprises the following steps.
S1, selecting yellow pearl oyster with the shell inner layer, obtaining connective tissues in the center of the mantle of the pearl oyster, and cutting to obtain small cell pieces; and subjecting the cell pellet to a sterilization treatment.
S2, selecting a healthy mature nacre with yellow inner layer, implanting a pearl nucleus into the pearl nucleus site through surgery, and sending the cell slice obtained in the step S1 into the nucleus site and attaching the cell slice to the pearl nucleus; ensuring that the cell sheet and the pearl nucleus are together resident in the nuclear site.
S3, putting a plurality of operated nacre into a group, and putting the nacre into a seawater pond for resting for 25-35 days; the specific rest time can be set according to the actual situation as long as the rest time is within the interval, such as 28 days and 30 days. And after the rest cultivation is finished, removing dead shellfish, cleaning attachments on the nacre, and continuously cultivating according to a conventional method.
And S4, after 2-3 months of cultivation, removing dead shellfish, cleaning attachments on the nacre, and continuing cultivation.
And S5, executing the step S4, repeating the step 4 or 5 times, and finishing the cultivation process.
Preferably, some pearl nuclei are spitted out in the cultivation process after the nucleus planting, and if the cultivation is carried out again, pearls are not produced, so that the cultivation cost is increased indirectly. In contrast, after the nacre is retired, the nacre with the attachments cleaned is firstly screened out by an X-ray machine, and then the nacre with the cores is continuously cultured. Through the steps, whether the nucleuses are reserved in the nucleuses of the nacre can be identified through an X-ray machine, and the nacre-producing body without the nucleuses can be found in time. Thus, the pearl producing shell bodies without the preserved pearl nuclei can be removed after the rest period, and the subsequent hanging-cultured pearl producing shell bodies are ensured to contain nuclei; the pearl yield of the cultivation is improved; the pearl producing shell body without the pearl nucleus can be cultured and planted with the pearl nucleus again; effectively reducing the breeding cost.
In addition, the nacre (pearl producing shell) can be recuperated before the nucleus planting operation, so that the success rate of the nucleus planting operation can be increased. The specific operation is as follows: and (5) putting the nacre selected in the step (S2) into a seawater pond for suspension culture, doubling the number of the nacre in each suspension culture cage compared with the number of the nacre in the normal suspension culture, and continuously culturing for 8-12 days. Wherein the water temperature of the culture seawater which is recuperated before the operation is kept at 16-27 ℃, and the dissolved oxygen is 6-10 mg/L. After the pearl oyster is recuperated before an operation, the physiological growth of the pearl oyster is inhibited, the gonad of the pearl oyster is not too full, the nucleus planting effect is good, the pearl oyster can be quickly recovered after the nucleus planting, the death rate after the nucleus planting is reduced, and the nucleus planting success rate is improved.
The present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents and are included in the scope of the present invention.
