| 为提高我国刺参的健康生态养殖水平,文章分析韩国红刺参与中国刺参的杂交,通过优势性状的定向选择育种,获得具有集优性状的刺参新品系,兼具韩国红刺参和中国刺参的品质优势,充分发挥韩国红刺参耐高温、夏眠时间短、生长速度快和体壁厚实等优点。养殖实验和研究结果表明:刺参杂交组比刺参对照组的生长速度提高超过25%,成活率提高超过24%;温度和盐度对杂交刺参稚参生长发育的影响显著,稚参阶段的最适温度为20℃~25℃,最适盐度为28~30;刺参杂交组的夏眠时间延迟,内脏未完全消退。根据基础研究结果,应进一步熟化技术,以企业为载体,开展控温室内育苗工作。 |

| Abstract: |
| In order to improve the level of healthy and ecological breeding of sea cucumber in China,this paper analyzed the hybridization of Korean sea cucumber and Chinese sea cucumber,to obtain a new line of sea cucumber with superior traits,by the selective selection of dominant traits,which has both advantages of Korean sea cucumber and China sea cucumbers,with full play of the advantages of Korean red sea cucumbers,such as high temperature resistance,short aestivation time,fast growth rate and thick body wall.The experimental study of China′s transformation culture found that the growth rate of hybrid was over 25% higher than that of control group,and the survival rate was over 24%.Temperature and salinity had significant effects on the growth and development of hybrid,and the optimum temperature was 20℃-25℃,and the optimum salinity was 28-30.The aestivation time of the sea cucumber hybrid group was delayed,and the internal organs did not completely disappear.According to the results of basic research,the technology should be further matured and the work of controlling seedlings in greenhouse should be carried out with enterprises as carriers. |
