近年来,我国珍珠养殖业有了飞速发展,海水珍珠年产量由1988年首次突破2吨大关已提高到现在的15至20吨;淡水珍珠发展速度则尤为惊人,1992年产量为300吨,据有关资料介绍现在已达到800至1000吨。尽管我国珍珠产量大,但我国珍珠优化加工技术相对落后,国内优化仅指漂白,很少涉及前处理和后处理,加工出的产品普遍存在
In recent years, with the rapid development of pearl aquaculture in China, the annual output of seawater pearl has exceeded 15,000 tons for the first time since it passed the 2-ton mark in 1988. The production rate of freshwater pearl is particularly alarming. In 1992, the output was 300 tons, According to the introduction of relevant information has now reached 800 to 1,000 tons. Although China’s pearl production is large, but our pearl optimization processing technology is relatively backward, domestic optimization refers only to bleaching, rarely involved in pre-treatment and post-processing, processed products are ubiquitous
