Abstract

The invention relates to a method for culturing fresh water large-nucleus pearls, which includes pearl nucleus picking, pearl nucleus inserting and pearl culturing, wherein the pearl nucleus inserting is divided into two steps, including culturing cell tissue mantle or biological cell that has multiplication capacity, adhering to the pearl nucleus, then putting the pearl nucleus into the nucleus site in the mantle and the visceral sac of an anodonta and harvesting pearls from the anodonta after 10 to 20 months' culturing for the first step; inserting the pearl nucleus with a diameter of above 15 mm into the pearl sac and conserving pearl for 30 to 50 months; the culturing of the cell tissue mantle or the biological cell thereof requires the preparation the balanced salt solution and the culture medium. The method is characterized in easy operation, high survival percent, large pearl diameter and thick pearl layer. Pearls of gem grade with the diameter of above 20 mm can be cultured.

Description

technical field

[0001] The invention relates to a method for cultivating pearls, in particular to a method for cultivating freshwater large-core pearls. Background technique

[0002] Now, in the general method of cultivating pearls in freshwater mussels, small pieces of cells made of the mantle are inserted into the mantle of the mussel, and the late pearls cultivated by this method are called non-nuclear pearls, and their diameter is small. The market price is low, and the economic benefit is not high. The production of nucleated pearls in China is mainly based on seawater nucleated pearls. The reason is that the seawater mother-of-pearl is relatively large, and the core insertion site is not located in the mantle but mainly in the visceral sac. It is difficult to insert cores in freshwater mussels, whether it is in the mantle or the visceral sac. It has not been practically applied in large-scale production, because there are problems such as high mortality rate, high nu...
