Problems solved by technology

That is, the cultivation period is relatively long, and the bead rate is low, which increases the cost of bead farmers in disguise and reduces the production efficiency.

Embodiment 1

[0017] (1) Breeding mussel selection: According to the applicant's application on March 3, 2009 and the published "Freshwater Cultivating Pearl Mussel Family Establishment and Its Breeding Method" (publication number is CN101491222), the mussels bred as breeding mussels, Carry out self-breeding or hybridization, and the small mussels cultivated are used as candidates for surgical inoculation of mussels or small mussels;

[0018] (2) Selection of surgically inoculated mussels and small mussels: Among the above-mentioned alternative mussels, select the same batch of 12cm-long mussels in the same batch of 1st instar mussels as the reselected mussels and small mussels, and select the same full length in the reselected mussels , but the whole weight is 20% larger than the average weight of the same batch of small mussels as candidate mussels, and then select the small mussels whose shell width is 15% larger than the average shell width of the same batch of small mussels from these c...

Abstract

The invention discloses a breeding method of an ultra-large nuclear-free pearl with good quality, comprising the following steps: selecting a raw oyster, selecting an operation raw oyster and a cluster oyster, inoculating, recuperating the operation raw oyster which is operated, injecting after operation recuperation, and culturing pearls. The invention overcomes the disadvantages of relatively long culturing period of freshwater ultra-large pearls, low ball rate and the like, which namely increases the cost of pearl farmers and lowers production benefit. The ratio of ultra-large nuclear-freeripe pearl cultured with the method of the invention is above 85%, and high-quality rate is above 60%. The pearl cultured with the method of the invention has big granule and favorable quality, so that selling price is high; thus, the breeding method of the invention improves the input-output ratio of culturing pearls, greatly improves the income of pearl farmers and is favorable for development of pearl breeding industry.

Description

technical field [0001] The invention relates to a method for growing freshwater pearls, in particular to a method for growing super-large seedless high-quality pearls. Background technique [0002] my country is one of the earliest countries in the world to catch pearls, and it is also the first country to cultivate pearls artificially. However, during the nearly 800 years from the 13th century to the 1960s, artificial cultivation of pearls stagnated, basically relying on natural pearls. In 1962, Professor Xiong Daren succeeded in artificially cultivating seedless pearls from river mussels. After 1964, freshwater pearl cultivation was successively carried out all over the country, especially in Jiangsu, Zhejiang, Hunan and other provinces. After the 1970s, my country carried out research on the artificial reproduction technology of river mussels and made breakthroughs, especially the successful artificial breeding of Hyriopsiscumingii and Hyriopsiscumingii and Hyriopsiscum...
