对55个不同地域的珍珠养殖基地的水质、底泥、珍珠色泽调查结果进行生物学分析与统计。结果表明:浅色珠是我国淡水珍珠的主流;三角帆蚌(Hyriopsis cum ingii)分泌浅色珠珠质的能力较强,平均月产珠量达0.70g/只;水体中元素的含量与底泥中的元素的含量基本呈正相关;珍珠的呈色与水体中不同元素的含量直接相关。
Biological analysis and statistics were conducted on the survey results of water quality, sediment and pearl color of pearl cultivation bases in 55 different regions. The results showed that light colored beads were the main stream of freshwater pearl in China. Hyriopsis cum ingii had a strong ability to secrete light-colored nodular beads with an average of 0.70g per month. The content of elements in water was similar to that of the bottom The contents of the elements in the mud are basically positive correlation; the color of the pearls is directly related to the content of different elements in the water.
