Abstract

The invention relates to a method for processing a mantle piece and for improving the quality of sea-pearl. The method is characterized as follows: chitobiose after isolation and purification is selected and is prepared into solution with the density of 0.5 to 3 percent by degerming seawater; the outer margin of non-pigment particles of the mantle which has strong fissionability is cut from the mantle piece shell, after the mantle piece is soaked for 5 to 10 minutes or placed for about 10 minutes after being applied with solution with similar density, the mantle piece is cut into a mantle piece with the length and width of both 4.5 to 5.5mm; the mantle piece which is processed by the chitobiose solution and a pearl core are put into a pearl culture bag that cultures pinctada margaritifera, and after 15 days, the pearl culturing shell which is implanted with the pearl core and the mantle piece which is processed by the chitobiose solution is transferred to mariculture water to culture pearl. The method can promote the division of the cell of the mantle piece effectively, can fasten the formation of the pearl sac and inhibit bacterial infection of operation, and the survival rate of the pear culturing shell, the core reserving rate and the excellent pearl rate can be increased by 20 percent, 15 percent and 15 percent respectively. The method has the advantages of simple implementation and obvious effect.

Description

A kind of method of handling mantle piece raising quality of sea water pearl

Technical field

The present invention relates to a kind of method that mantle piece improves quality of sea water pearl of handling.

Background technology

China is since nineteen sixty-five is successfully carried out the artificial breeding of pteria martensii, and the sea water pearls aquaculture development is rapid, becomes one of mariculture pillar industry of Guangdong, the coastal some areas in Guangxi and Hainan.Obviously descend thin layer pearl, dirty pearl, lopsided pearl, the high phenomenon of small-sized pearl rate be on the rise (Wang Aimin, Shi Yaohua, 2003) yet in recent years, pearly shellfish inserts nuclear back lethality height, receive pearl index, commodity pearl and high quality pearl ratio.Though the research topic at aspects such as the growth of pinctada and build sizes has been subjected to relevant departments and scholar's attention, and many fruitful researchs have been obtained, but, on the important links of growing cultured pearls such as processing of mantle piece and pearl nuclear, also do not make great progress, somatotropin etc. are handled behind the mantle piece the action effect of pearly shellfish survival rate, core-remaining rate and excellent pearl rate etc. significantly (Jin Qizeng etc., 1998; Illiteracy is encouraged U.S. etc., and 1996).

Summary of the invention

In order to overcome survival rate, core-remaining rate and the low defective of excellent pearl rate of existing mantle piece treatment technology, the purpose of this invention is to provide a kind of method that mantle piece improves quality of sea water pearl of handling, less demanding in the operation, can not cause additional injury to shellfish, can effectively promote the division of mantle piece cell, quicken the formation of pearl sac, improve pearly shellfish survival rate, core-remaining rate and excellent pearl rate.

The technical solution adopted for the present invention to solve the technical problems is:

Select chitosan oligosaccharide (Chitosan oligosaccharide, molecular weight≤5000, the molecular formula: (C of separation and purification ₆H ₁₁NO ₄) _n, chemical name: β-1,4-oligomerization-D-glucosamine, or chitin oligo saccharide, amino-oligosaccharide), be mixed with the solution that concentration is 0.5-3% with the degerming seawater.

Cut the peripheral edge portion that has the outer embrane than the outer embrane non-pigment particle of strong splitting ability from the mantle piece shellfish, soak mantle piece after 5-10 minute, perhaps similar concentration solution is smeared the back and was placed about 10 minutes, is cut into the mantle piece of long and the wide 4.5-5.5 of being millimeter again.

The mantle piece and the pearl nuclear of chitosan oligosaccharide solution-treated are implanted in the bag of growing cultured pearls of pinctada together, recuperated after 15 days, the pearly shellfish of implanting the mantle piece of pearl nuclear and chitosan oligosaccharide processing is transferred in the marine culture water grows cultured pearls.

Described degerming seawater is mixed with the solution that concentration is 1.0-2.5%, soaks mantle piece 6-9 minute.

The invention has the beneficial effects as follows, can effectively promote the division of mantle piece cell, accelerate the formation of pearl sac, suppress the operation bacterial infection, pearly shellfish survival rate, core-remaining rate and excellent pearl rate improve 20%, 15% and 15% respectively.Using method is simple, and effect obviously.

Embodiment

Embodiment 1:
