I. Harvesting pearls (a) The time for the culture of pearls is 2~3 years (generally 3 summers and 2 winters). The larger pearls will exceed the load of the mantle, which will cause shedding or the formation of shell beads. From the point of view of non-nuclear pearls, the one-year-old pearls are rod-shaped for farming, and few are made into rounds; ovals or rounds are produced for two years of breeding; rounding increases for three years. (ii) Pearl harvesting should be conducted during the harvest season, and it can also be done in spring. However, since the growth of pearls has almost stopped throughout the winter, in order to shorten the cycle of breeding and save manpower and material resources, it is still best to harvest after the dense layer of pearls is formed in the early winter season. (3) The method of harvesting will transport the oyster-cubes to the room, cut the adductor muscles with a slicing knife, and dig out the pearls with scorpions, hooks or hands. However, in order to make better use of the cultured pearls for the cultivation of the regenerated beads, it is possible to carry out the live picking of the beads, which is particularly suitable for the first time when the beads are cultured with large particles, good luster and high quality. When taking the bead, you should drain, open the shell, stopper, wash, then use a probe to open a wound, use a curved crest to force the pearl out of the wound with proper force; or use a top fork to first hold the pearl, gently horizontally Push it, and the other hand uses a needle to draw a cut in the pearl contact on the epidermis and push the pearl out. After the pearl is pressed out, the pearl sac is generally returned to its original position. It is best to use a rounder and other tools to sort the wound so that the pearl sac is not exposed. Second, the processing of pearls (1) Wash the pearls first with a surface cleaner, such as detergent, and rinse them with running water. Then dry them with white silk turpentine. Wipe the surface of the pearls to make the pearl luster shine, and then grade the packaging. (b) Processing of pearls 1. Use pearls to make a variety of jewelry, such as necklaces, rings, bracelets, earrings, corsages, hair accessories and so on. 2. Pearls processed into fine powder can be used as raw materials for proprietary Chinese medicines. Hydrolyzate can be used as a component of pearl wine, pearl cream, eye drops, anti-aging drugs. 3. Abnormal pearl processing: After grinding all kinds of deformed beads into round or near-circular shape with vermiculite, mix it with soaked sawdust, put it in a cloth bag, rub it and polish it, until the pearl crystal shines, and finally remove the pearl wash. Net, dry.
Knitting Woven bale wrap netting can be also made into width 1.3m, length can be 2000m,3000m,3600m, etc.
The Bale Wrap netting must be strong enough during the bale processing, no broken or fracture.
As the silage bale usually be stacked outdoor, the bale wrap netting should also be UV-resistance, ageing resistance.
