We set out to explore and innovate in terms of the natural form of pearls, making the shape of pearls from round to massive and to line segments. After more than three years of hard work, the product beads were produced. Passed the market test, the result is satisfactory. The pictographic bead not only shortens the production cycle by two years compared with conventional beads, but also has a market price of 1,400 to 2,000 yuan per kilogram of the bead, which is 3 to 4 times the conventional round price and a considerable net profit.
First, preoperative preparation
1. Preoperative training Surgical fistula cultivation requirements for the end of the mud, and can not use chemical fertilizers and water management (we use the pig farm biogas digester fertilizer). Surgical procedures need to be meticulously cultivated and managed for 12 years before they can be used as surgical tools.
2. Surgical gills Select surgery gills require the body length of 10 cm or more, the edge of the clam shell is soft, closed shell, shrinking foot reaction is sensitive, strong water spray, plump and thick, feel heavy.
3. To promote the cultivation of the grafts before surgery, from the bottom to the hanging cultivation, carry out intensive cultivation, and promote the thickness of the mantle. This process is also a preferred finishing process. The crickets that meet the surgical conditions are kept in batches. We use a long-belt (10003000) centimeter X15 centimeter clip for hanging. Aquaculture water quality requires fertilizer, live, tender and cool. The hanging depth should be controlled within 20 to 30 cm from the water surface. The water layer is rich in plankton and is conducive to the rapid fattening of the surgical gills.
4. Hanging up for 10 to 15 days after hanging up for surgery. If you hang up for too long, it will cause excessive body fat, axe and other internal organs too large, brittle film, cut a small piece easy to roll and increase the difficulty of surgery to reduce the quality of inoculation.
5. Surgical season selection According to our practice of breeding pearls, the best period for the inoculation surgery season should be the Lunar Valley rain to the summer solstice, and then select the second half of the lunar autumn equinox to frost. The larvae that were inoculated at this time period not only had high survival rate, but also had fast bead molding, good bead shape, and good quality. If it is too early or too late, the water temperature is relatively low and pearls are slow to form, which can easily lead to unfavorable factors such as frozen beads and rot. In the hot season, it is easy to cause surgical trauma and death, and the survival rate is low. .
6. On the day of the operation, the cervix should be cleaned and the beads and lice should be randomly sorted. In the same batch of cockroaches, the selected clams were relatively larger than the cockroaches, the cocoon shells were intact and the marginal film growth lines were obvious. With the test, points are held separately and held in their respective flow sinks (pools).
Second, production
1. The surgical tools are basically the same as the ones used for inoculating conventional beads. Only the channel needles are slightly different. The total length of the channel needles is about 20 cm, half of which is rounded and the other half is long and flat; the head is slightly pointed and the back As the tongue slowly widens, the widest point is 0.2 cm or 0.3 cm. It is slightly arced and made of stainless steel. It is used for opening and styling and for film feeding. Cork 2 per group, each cork thickness 0.7 cm.
2. The specific method of filmmaking is tear film method. Surgical procedures and. Disinfection methods, etc. are consistent with inoculation of conventional beads. The difference is that we create a combination of small pieces and style. For example, when producing pictograms, the small pieces are cut into strips. The length and width of the strips are determined according to the length and width of the strokes. The width of the small pieces is 0.2 to 0.3 cm and the length is 2 to 4 cm. The button beads cut the small pieces. Into a prism.
Third, then planted tablets
1. Prepare open shells to gently open the double hulls of the cultured pearls, then place a cork on the front and rear ends of the larvae, and then use a stencil to set the stalks of the larvae and axe to one. Side, ready to implant.
2. The position of the graft is selected in the central membrane of the posterior half of the corpus callosum.
3. The number of implants such as "+", "#", "Feng", and "No" are on each side; there are three teeth on each side such as toothpick beads, button beads, and bullets.
4. At the beginning of grafting, first use a crochet hook to open the incision, then use a channel needle to shape it, and then send it to the tablet. Gently place the pearls that have been implanted into the holding water tank (pool), and wait for the hatchery to be transferred to the culture tank in time.
Fourth, pearl aquaculture and management
1. Pearl ponds require that the aquaculture ponds have a water depth of 150 cm or more, and the area is better.
2. Breeding stocking density of pearl stocking density 800 to 1000 per mu.
3. Recovery period water quality Pearl pipa just finished the surgery, there is a recovery process of rest and recuperation, at this time the aquaculture pond water quality requirements relatively thin, transparency should be greater than 40 cm.
4. Recovery period management According to our experimental results, the water temperature in the pre-operative period (Gu Yu) is relatively low, so the water depth for hanging should be 10 to 35 cm. By the end of the surgery (summer solstice), the temperature of the water is getting higher, and the depth of water for hanging should be 50 cm. ,
5. The management of production period After about one month of recovery period of aquaculture management, pearl aquaculture has entered normal production period management, and the depth of hanging cultivation is adjusted according to the temperature. In general high temperature or cold days, the depth of hanging is 50-60 cm. In other periods, it can be raised to 25-30 cm.
6. Eco-management Yuzhu Lake adopts suitable amount of white plover, flower scorpion, squid, grass carp and other fish species, and can also stock a small amount of green prawn species. Generally, the production of mu fish is 75 to 100 kilograms and shrimp production is about 20 kilograms.
7. The Pearl River pond water quality regulation and management The Pearl River pond water body requires a transparency of 30 cm, and the water color is yellow-green. Water quality management is mainly accomplished through measures such as fertilization, application of lime, flushing, and water change, and the water quality is adjusted in time according to phenomena such as water transparency and daily changes in water color. And regularly pouring lime slurry, lime consumption of 10 kilograms per acre, each year in the beginning of April to mid-November, every 12 to 20 days splashing once.
8. Health inspections Carry out occasional health checks during the cultivation period so that problems can be found and problems solved. After careful cultivation and management of the two summers and two winters, you can use the beads.
