【摘要】 1985年5月从菲律宾引进了异枝麒麟菜(Eucheuma striatunl)并在海南岛进行了实验生态学和栽培方法的研究。实验结果表明,适温在26°C左右、光强在140μE/(m~2·s)左右时,生长较快,日生长率可达10％左右。经两年的实验,找出了适宜于海南岛区域的水下筏式养殖法,目前正在实验推广中。更多还原

【Abstract】 Since cultivation of good quality and productive highly species is an effective way toincrease production, a rapid growing species--Eucheuma striatum was introduced to Hainanlsiand from the Philippines in 1985 by the Institute of Oceanology, Academia Sinica and a 2-year study showed promising results. The average daily growth in weight reached 10% at a favourable temperature of about 26℃. Experimental results showed that timely cutting of the plant accelerated growth and was an effective way to obtain new cuttings for cultivation, because of the improved light condition. New cottings of 50 g in weight is suggested to be used as "seeds" and old part of the plant should be harvested. E. striatum grows fast but the thalli are easily broken and lost. In regions with strong wind like Hainan Island, a key point is the selection of the cultivation methods. It is suggested that the under-water raft method is applicable in such places. At present, artificial cultivation with this type of raft will expand to other regions in Hainan Island.By the end of 1986, 90 mu of the seaweed were cultivated in Qionghai and Chengmai Counties. Evaluation of the underwater raft method shows annual production may reach 400 kg dry weight per mu with a net income of about 600 yuan/mu.更多还原
