Embodiment

sea water pearls cultural method, is divided into the harvest stages of pearl shell artificial breeding stage, female shellfish forming stage, nucleus insertion and pearl stage, recuperation period stage, the stage phase of growing cultured pearls, pearl.

in the pearl shell artificial breeding stage.Nursery work is from selecting shellfish, namely be select some shellfish bodies healthy and strong according to need of production, sexual gland is plentiful, ripe individuality does close shellfish, post-mortem method is adopted manually to draw the way of smart ovum or induced spawning fertilization to obtain a large amount of young, when after embryonic development about 19 hours, statistics larva amount is by the density of cultivating water body 1-2/ML, move on to seedling rearing room to cultivate, first three days adds water, the fresh filtering sea of later irrigation and drainage every day, after changing water, throw in unicellular in right amount, essence algae, single algae and yeast, larva is allowed to grow up strong and sturdy, throw in seafood process, clean lamina affixad is hung in nursery pond, when seedling grows up to about about 2CM on lamina affixad, start to receive seedling, then by seedling wash clean, be loaded on respectively and hand over silk screen to protect in cage, in sea area hanging culture.

at female shellfish forming stage.Seedling after the hanging culture of sea area to inserting running check seedling cage before core, remove mud and end marine growth, and change mud depending on growth of seedling situation and time-division seedling, sucking-off seedling, children shellfish and the cultivation density becoming shellfish, lower water cultivates 3 months can up to 2CM, and cultivation half a year can up to 4-5CM, 1 anniversary that cultivated can up to about 6CM, and 2 anniversaries can up to about 7CM.Can be used as female shellfish and be used for nucleus insertion and pearl, breeding way adopts buoyant raft and multigun type to hang down hanging culture.

nucleus insertion and pearl.As everyone knows, pearl is the outer embrane of shellfish, be subject to the exotic entered in body, friction as the grains of sand, parasite etc. stimulates, or the pathology of itself comes off, and is absorbed in connective tissue by epidermal cell, and autotomize propagation, or the deformity propagation of outer embrane epidermal cell forms pearl sac, secretion nacre, the coprecipitation coating of the multiple one deck of layer and the ball bead that formed.According to the principle that natural peral is formed, to female Bei Jinhang operation, then pearl core is inserted soft material, subsequently, transplant one piece of mantle piece, make it be close to pearl core and carry out In vivo culture.The outside epidermal cell of small pieces to come off and to be stained with pearl core surface mobile from base film layer, constantly breeds, forms pearl sac gradually, be precipitated as nacre at core exocrine secretion nacre, a bright pearl of congealing in the course of time.

nucleus insertion and pearl operates by following program:

step one: female shellfish gives pre-treatment, performing the operation around the Spring Festival first three ten to four ten days, when water temperature 17 to 18 is spent, cleans out female shellfish, loads in process cage; Cage surrounding hole is little, reduces current, reduces appetite, causes anoxic, thin soon, every cage 110-130, depending on female shellfish Individual Size: 30 grams of shellfishes 130,35 grams of shellfishes 110,100,40 grams of shells; Then vinyl cover is covered, in right up and down sea area hanging culture, the depth of water 2.5 to 3 meters, winter, water temperature was low, and plastics cage periphery should add plastic film and surround; Suppress the female shellfish vigor of adjustment, untreated female shellfish outer embrane is transparent thick, and after process, then outer embrane is thin in white;

step 2: hasten parturition, discharge smart ovum, because the plentiful female shellfish of sexual gland is unfavorable for that executing art inserts core, execute art reluctantly, ovule tail is many, effect extreme difference, hastening parturition is a large amount of oxygenation in the sink, and carry out under promoting water temperature 2-3 degree condition, clean up through processed good female shellfish, load in square plastic cage, every cage 240-250, tiling is put in hastens parturition in groove, vertically-arranged is put in a suitable place to breed, the superiors' shellfish cage is not added a cover, after rear ejaculation puts ovum, during draining feculence, start draining, pour water simultaneously, keep water level balance, clarify to water colour, when essence ovum drains only, then the female shellfish of injection of ozone process, its objective is sterilizing and reduce the death of female shellfish and enteric infection, after two to three hours, discharge seawater in tank, shift out female shellfish, pearl cage groove of hastening parturition can be seamed into square with plastic color strip cloth, additional plank is fixed, heat up with hot water, aerating machine is used to carry out oxygenation,

step 3: female shellfish recuperation, the female shellfish after hastening parturition has a delicate constitution, after shifting out with hastening parturition, should load in recuperation cage in time, about every cage 100-120, after adding a cover, move on to right up and down sea area hanging culture 7 to 14 days, rejuvenate female shellfish, being used for executing art during sexual gland translucent, to insert core best, general recuperation about 10 days, and about 80% is qualified, current are fast, process two days less; Water temperature is low, and current are slow, multiprocessing two days;

step 4: execute art and insert core, executes preoperative, the necessary strict sterilization of all operational tool, and female Bei Bixu cleans out,

first carry out bolt mouth, with opener, female shellfish bivalve is strutted, fill in chock after allowing and insert core in order to executing art, then outer embrane is cut, piece shell should select shell pearl layer to be silvery white in color, pink, blue health 2 years shellfishes, first insert from ventral margin after piece shell with scalpel, cut off closed shell flesh, shellfish body is divided into two, then the shellfish cheek is pushed aside, below lip from cheek end cut outer embrane base or its in pad, in order to avoid bending effect of contraction chip rate and quality, then mantle piece is made, aim at colo(u)r streak, finishing outer embrane, along in colo(u)r streak outer four six the slitting shape of ratio, dip in filtering sea with degreasing cotton again and wipe mucus, then with the red Gong Shui dyeing of 2%-3%, sterilization, be cut into the blockage of 2 to 3 millimeters, depending on pearl core size, general small pieces size is 1/3rd of core footpath, drip upper several filtering seas for subsequent use, finally carry out executing art and insert core, female shellfish is placed on operating table, the cheek leaf on the right core limit of female shellfish is pushed aside with dull and stereotyped pin, check whether and meet standard, pearl core can be inserted, then an arc incision is cut at sufficient base portion, a passage is done to inserting core position along otch, send into by core position with nucleus sending device picking pearl core immediately, generally send two pearl cores, i.e. left and right bag, macronucleus inserted by left bag, small nut inserted by right bag, difference 0.25mm, 30 grams of shellfishes insert 5.5-6mm pearl core, 40 grams of shellfishes insert 6-6.5mm pearl core, 45 grams of shellfishes insert 6.5-7mm pearl core, core position is delivered to along passage again and pearl core is close to small pieces pin picking mantle piece, sending during sheet to lean on the one side of shell pearl layer to be attached on pearl core in small pieces front, in order to avoid form Su Zhu, return small pieces pin immediately, namely operation accuses complete.

in the recuperation period stage, it is characterized by: female Bei Shi is postoperative puts into recuperation cage, 130, every cage, in right up and down sea area hanging culture 30 days, allow its healing of wound as early as possible, form pearl sac, secretion nacre, regularly inspection in 3-5 days simultaneously tells core, death condition, process in time of pinpointing the problems.

growing cultured pearls stage phase.Female shellfish after recuperation, loads the taper cage of diameter 38CM, 35, every cage.Hanging culture, after 14 days, does X-ray examination, removes and tells core shellfish, use rectangular pieces cage, 60, every cage, in the Sea Area Off hanging culture that current are unimpeded, raft along the line, cultivation water layer about 1 meter, receives the pearl previous moon, about four meters water layers, temperature stabilization, reduce infrared radiation, how white pearl matter is simultaneously, good luster, pearly shellfish rinses once for 10 to 15 days, remove attachment and end marine growth, wash Becquerel to promote that pearl shellfish shrinks, increase secretion nacre, be careful during operation, avoid strenuous vibration, grow cultured pearls about 1 year phase, pearl more than layer 0.6mm.

pearl harvest stages.General in February in December to next year, because severe winter water temperature is low, nacre secretion is slow, pearl color and fineness good, the smooth exquisiteness of pearl layer, glittering and translucent, lovable, receive pearl and adopt post-mortem method, kill shellfish and get pearl, focus on, first wash with clear water, then embathe with soap or liquid detergent, again with 40 degree of warm water cleanings, soft cloth is dried, after sifting sort, be packaged to cabinet with cloth bag to preserve, do deep processing or sale more as required.
