淡水养殖珍珠是水产珍品生产的一个项目,为仿照天然成珠原理育成。即取河蚌外套膜表皮制成细胞小片,用手术的方法植入宿主蚌的外套膜上;或把用贝壳质做成的珠核插入,并随同植入细胞小片与核密切,使细胞小片依赖宿主蚌的结缔组织供以营养,增殖成珍珠囊。由珍珠囊分泌珍珠质沉积于囊内或核上,经2—3年的培养,即形成珍珠。只植细胞小片的生成无核珍珠;插核植片的生成有核珍珠。珍珠因其独道的药理作用和装饰价值,驰名于国内外市场,且需要量很大。北方有一定的生产潜力。为了增加出口,支援四化建设,我们于1977年冬在贾庄公社鱼种场开展了北方
Freshwater cultured pearls are a project of aquatic treasures production, which is modeled on the principle of natural beading. Take the mussel epidermis made of small pieces of cells, surgically implanted into the host mussel mantle; or made of shellfish made of beads inserted, and with the implantation of small pieces of cells close to the nucleus, the small pieces of cells Relying on the host mussels connective tissue for nutrition, proliferation into pearl sac. Nacre secretion by the pearl capsule deposited in the cyst or nucleus, after 2-3 years of culture, that is, the formation of pearl. Only the formation of small pieces of cell-free seedless pearls; nucleus inserted nucleus pearl nucleus. Pearl because of its unique pharmacological effects and decorative value, well-known in domestic and foreign markets, and in great demand. The north has a certain production potential. In order to increase exports and support the building of the four modernizations, we conducted the northern part of Jiazhuang Commune fish farm in the winter of 1977
