2005年3月～2007年12月,通过系列实验比较了术前处理和养殖模式对三角帆蚌和褶纹冠蚌培育附壳造型珍珠效果的影响。结果表明:1)术前处理能显著提高三角帆蚌及褶纹冠蚌的成活率、成珠率和优珠率(P<0.05)。2)三角帆蚌及褶纹冠蚌鱼蚌混养组的成活率、成珠率和优质珠显著大于对照组(P<0.05)。手术蚌处理的合适密度为3000只/667m2,透明度5060cm,处理时间2030d;蚌鱼混养的草鱼和鲮鱼放养密度为50～70尾/667m2,鲢鱼20～30尾/667m2,鳙鱼50～60尾/667m2,三角帆蚌或褶纹冠蚌放养密度1200只/667m2。
From March 2005 to December 2007, a series of experiments were conducted to compare the effect of pre-treatment and culture modes on the pearl-shell pearl cultivation of Hyriopsis cumingii and Pleurotus ostreatus. The results showed that: 1) Pretreatment significantly increased the survival rate, the rate of pearl formation and the rate of excellent pearl (P <0.05). 2) The survival rate, pearl yield and quality beads of Hyriopsis cumingii and Pleurotus ostreatus were significantly higher than those of the control group (P <0.05). The suitable density of operation mussels is 3000 / 667m2, the transparency is 5060cm and the treatment time is 2030d. The stocking density of grass carp and bighead carp is 50-70 / 667m2, 20-30 / 667m2 of silver carp and 50 ~ 60 tail / 667m2, Hyriopsis cumingii or Plicata cremoris stocking density of 1200 / 667m2.
