北方用维尼纶苗帘培育海带夏苗的实验研究
Experimental research on summer seedling cultivation of Saccharina japonica using vinylon rope breeding screen in North China
摘要
Abstract
According to differences in seedling rope used in South and North China, this study was conducted at the State Seed Breeding Farm of Kelp in Yantai using vinylon and palm rope breeding screens in the same workshop. Gamete development and young sporophyte growth were continuously monitored for detecting the difference be-tween the two types of breeding screens. The results indicated that the rates of gamete development and sporophyte growth were significantly faster using the vinylon screen than using the palm screen (P < 0.05). After sporophyte formation, from breeding days 15 to 31, the relative growth rate of sporophytes was significantly higher using the vinylon screen than using the palm screen (P < 0.05). On breeding day 55, the mean length of the sporophytes using the vinylon screen increased to 1.53 cm± 0.13 cm and reached the size to be fostered out of the workshop on the sea, whereas that of the sporophytes using the palm screen only increased to 0.47 cm ± 0.03 cm on an average. When seedling cultivation ended on breeding day 70, the sporophytes on the palm screen increased to 1.78 cm± 0.19 cm on an average, whereas those on the vinylon screen had a mean length of 7.87 cm± 1.35 cm. The general cost for cultivating 10, 000 seedlings using the vinylon breeding screen was 23 yuan RMB, with 600000 seedlings/1-m3 seawater being produced; in contrast, the general cost for cultivating 10000 seedlings using the palm breeding screen was 31 yuan RMB, with 400000 seedlings/1-m3 seawater being produced. In conclusion, the use of vinylon breeding screens for cultivating summer seedlings of kelp in North China is practical and feasible and can reduce the cost by 25.8％.关键词
