Nucleus inserting and pearl culturing method for self-absorbing pearl nucleus of pearl shell

Abstract

The invention relates to a nucleus inserting and pearl culturing method for a self-absorbing pearl nucleus of a pearl shell, and belongs to the technical field of sea (fresh) water pearl cultivation. The method comprises the following steps of: selecting a nucleus inserted shell which opens naturally; fixing an open angle of the nucleus inserted shell; opening a pallium and a gill tissue by using a small piece; respectively inserting one or more self-absorbing pearl nuclei on the pearl layers of two shells, wherein the self-absorbing pearl nuclei are hemispherical or pictographic and the bottoms of the self-absorbing pearl nuclei are provided with sucking discs; fixing the sucking discs inside a shell body; closing the nucleus inserted shell; and placing the nucleus inserted shell into water. The invention is improvement on a method for inserting a nucleus of a pearl which is attached to the shell. Due to the adoption of the self-absorbing pearl nucleus which is attached to the pearl layer, the method has the characteristics of simple operation, high work efficiency, fixed absorption without a pearl discharging or displacement phenomenon; the nucleus inserted out of water is substituted by being inserted in water, so that a vital function of the nucleus inserted shell is not affected basically; survival rate and pearl remaining rate are high; pearl quality is uniform; and cultivation benefit is remarkable.

Description

technical field [0001] The invention relates to a method for inserting and nurturing pearl oyster self-absorbing pearl nuclei, and belongs to the technical field of sea (fresh) water pearl cultivation. Background technique [0002] At present, domestic sea (fresh) water pearls have formed a whole set of methods for cultivating pearls by inserting nuclei. In addition to cultivating free pearls, they also culture pearls with shells. Generally, 502 glue is used to paste the bead nucleus for cultured shell beads, or shell drilling and stringing are used to reinforce the bead nucleus. Except that the smell of 502 glue stimulates the shellfish to cause phytotoxicity, these two methods of inserting nucleus have long operation time out of water and work The efficiency is low, the recovery of the oyster is slow, the pearls are deformed, and there are few complete pearls, which hinder the development of the pearl breeding industry.

Problems solved by technology

[0003] The present invention overcomes the shortcomings in the prior art, and solves the problem of high shellfish death rate, low bead retention rate, poor pearl quality and low breeding benefits caused by the current shellfish glue sticking and drilling and stringing to fix the bead core culture with shell pearls To solve the problem of pearl culture, provide a pearl oyster self-absorbing bead core insertion nucleation bead cultivation method
