At the earliest, people used the method of preoperative treatment to inhibit the physiological vitality of implanted shells to reduce the occurrence of "vomiting" nuclei. In recent years, technical measures such as adhesive wound bonding and surgical suture wounds have been used to prevent the occurrence of "vomiting" nuclei. , but the effect is not satisfactory

Embodiment 1
[0029] Embodiment 1: the nuclear fixer is made of base and solid nucleus rod.
[0030] Such as figure 1 As shown in -4, the base is composed of a seat body, a fixed steel sheet 4, a movable steel sheet 5, bolts 6, pointed bolts 7, and nuts 8, and the seat body is composed of a bottom plate 1, a side plate 2 and an upper plate 3 , the bottom plate 1, side plate 2, and upper plate 3 can be made of a stainless steel plate through processes such as cutting, bending, and polishing to make a U-shaped structure, and the fixed steel sheet 4 is welded on the side plate 2, so that the upper plate 2 The inner surface is on the same plane as the top of the fixed steel sheet 4, drill holes on the bottom plate 1, the fixed steel sheet 4, and the movable steel sheet 5, and then weld the nuts 8 to the drilling positions of the bottom plate 1 and the fixed steel sheet 4 respectively, and weld them to the bottom Spike bolts 7 are screwed into the nuts 8 of the plate 1, and the movable steel s...
Embodiment 2
[0038] Embodiment 2: the nuclear fixer is made of base and solid nucleus rod.
[0039] Such as Figure 5 As shown in -8, the base is composed of a base plate 1, a fixed steel sheet 4, a movable steel sheet 5, a bolt 6, and a nut 8. The base plate 1 and the fixed steel sheet 4 can be made of a stainless steel plate by cutting, bending, polishing, etc. , drill holes on the fixed steel sheet 4 and the movable steel sheet 5, and weld the nut 8 at the drilling position of the fixed steel sheet 4, then connect the movable steel sheet 5 and the fixed steel sheet by the bolt 6 and the nut 8 on the fixed steel sheet 4 Piece 4 is connected.
[0040] Such as Figure 10 As shown, one end of the rod body 10 of the solid core rod adopts an elbow structure, and the end is provided with a sheet-shaped pressing block 11, and the other end is provided with an operating handle 9.
[0041] Utilize the nuclear-fixing device of embodiment 2 to cultivate the mandatory nucleation method of nucleat...

Abstract
The invention discloses a forced nucleus retention method in nucleated pearl cultivation and a nucleus retainer used in the method. The nucleus retainer comprises a nucleus retaining bar and a base, wherein the nucleus retaining bar is used for retaining a nucleus, and the base is used for fastening the nucleus retaining bar to a pearl shell. The method includes: fastening the base to the edge of the pearl shell through bolts or fastening the base to the outer side of the pearl shell in an adhered manner, extending one end of the nucleus retaining bar into an outer holding cavity of the pearl shell, exerting certain pressure to hold the nucleus retaining bar onto the outer side of a visceral sac at the position of the nucleus, and fastening the other end of the nucleus retaining bar onto the base; placing the pearl shell in culture water for 10 to 15 days of temporary culture, and removing the nucleus retainer; and forcedly retaining the nucleus which is implanted and has a wound healed in the pearl shell without 'exposure'. The forced nucleus retention method and the nucleus retainer are effective in nucleus fixation, nucleus retention rate of nucleus implanted shells can reach 100% under experimental conditions, and the problem that a nucleus of a large nucleated pearl is 'exposed' during culturing is solved.
Description
technical field [0001] The invention relates to a method for cultivating large nucleated pearls, in particular to a forced nuclei retention method for cultivating nucleated pearls and the utensils used in the method. Background technique [0002] As we all know, the nucleation operation method of cultivating nucleated pearls is: use an open knife to make an incision at a suitable part of the epidermis of the viscera sac of the pearl oyster, and then use a nuclei feeder and a slicer needle to separate a round bead nucleus and a piece of mantle. The small piece is implanted into the visceral sac of the pearl oyster through this incision, and the nacre-secreting side of the mantle piece is close to the bead nucleus; the mantle piece tissue proliferates around the bead nucleus in vivo to form a pearl sac, and the nacre secreted by the pearl sac cells is deposited on the pearl nucleus. Nuclear pearls are formed on the surface of the nucleus. Therefore, whether it is cultivating ...
