我国河蚌资源丰富,分布地域广,用来进行人工培育珍珠的河蚌种类较多,就安微省现况而言,有三角帆蚌、褶纹冠蚌、背角无齿蚌等,但常用的育珠河蚌乃是三角帆蚌和褶纹冠蚌。以三角帆蚌为例,在一般情况下,生产单位培育珍珠时,是用一只三角帆蚌做制片蚌(即“供体”蚌),另一只三角帆蚌做育珠蚌(即“受体”蚌)。然后用人工方法将制片蚌的小片移植到育珠蚌的外套膜中,经过三年左右的培育便可形成珍珠。在珍珠生产中,常常出现一些天然的彩色珍珠。这些彩色珍珠的产生因素是多方面的。一般认为,是与制片蚌小片的特性有关,也就是说,制片蚌小片的“颜色”决定了以后经人工移植后所形成的珍珠的颜色(注:实际上小片是无色的,小片有没有“颜色”,是看外表皮下方的珍珠层有没有颜色,若珍珠层是紫色,那么此处珍
Our mussel is rich in resources and widely distributed. There are many species of mussel used to artificially cultivate pearl. In terms of current situation in An-Pei province, there are Hyriopsis cumingii, Cristaria plicata, Commonly used Yubeizhu mussels are clam mussels and crest clam. In the case of Hyriopsis cumingii, in general, when pearl production is nurtured by a production unit, a Hyriopsis cumingii (“donor” clam) “Receptor” clam). Then a small piece of mussel was transplanted into the mantle of pearl mussel by hand, and after about three years of cultivation, pearl could be formed. In the production of pearl, there are often some natural colored pearls. The production of these colored pearl is multifaceted. Is generally believed that the film is related to the characteristics of small pieces of mussels, that is, the production of small clam pieces of “color” determines the color of pearl after the formation of the post-transplant (Note: In fact the small pieces are colorless, small pieces There is no “color” is to see whether there is no color pearl layer below the outer skin, if the pearl layer is purple, then Jane
