Cultivation of Nanzhu in Nanzhu

Seawater pearls adopt the technology of "nuclear insertion culture".

From 65438 to 0965, Hepu Pearl Farm in Guangxi cooperated with Nanhai Institute of Oceanography to achieve successful artificial seedling raising, which was the first successful artificial seedling raising of Pinctada fucata in China. Since then, the propagation and breeding of pearls have all been carried out manually, which has improved the situation that natural Pinctada Hepu was facing extinction at that time. "Artificial cultivation of shellfish fry" won the 1976 National Science Conference Award. Pearl collection was changed to artificial culture. Only 1965, Hepu harvested 33 kilograms of pearls.

1966, Hepu pearl farm adopted scientific methods to cultivate pearls, which shortened the cultivation cycle of artificial pearls from the past three years to more than one year, and increased the output from about 10,000 pearls 10 kg to more than 24 kg. Since then, the pearl breeding industry has entered a brand-new development period, and the marine pearl breeding industry in China has turned a new page, and Nanzhu has begun to glow again. Since the end of last century, artificial breeding technology has been quite mature. Pearl farms in the southern coastal areas of China have not only mastered advanced scientific breeding technology, but also constantly summed up experience, pioneered and innovated, and developed new varieties. After more than ten years' exploration, Beihai Renshi has cultivated colorful pearls such as rose, emerald green and sea blue with black butterfly, white butterfly and Malpighia as mother shells by biotechnology. And applied for a patent for invention. Through expert appraisal, this technology fills the international gap. An old bead farmer in Hepu also cultivated beads.

Since the beginning of this century, pearl farmers, after experiencing the experiences and lessons of rough, poor quality and low price in previous years, have carried out intensive cultivation, done a good job in rare planting of pearls, and vigorously promoted a series of high and new technologies such as deep-water pearl cultivation, preoperative treatment, perspective nuclear insertion, large nuclear insertion, single nuclear insertion and colored pearls, and achieved good results. The output of pearls has been greatly improved, and the pearls produced are thick and shiny, with a commodity rate of 95%.
