根据欧盟项目的总体研究计划 ,在室内和围隔实验中研究了海带幼孢子体在不同温度条件下的生长情况和光合作用曲线 ,得出幼孢子体在 15°C下生长情况最好 ,而且其长度和重量的日增加量均和温度有线性相关关系。 Pm 值在 15℃时为 5 79mol O2 / (g DW· h) ,围隔实验中为 6 4 2 (mol O2 / (g DW· h)。由于围隔实验海区的光照强于室内 ,使得围隔中海带的光合作用曲线其光饱和点高于室内实验海带的光饱和点。海带光饱和参数 (Ik)与温度有线性相关关系 (R2 =0 .736 7,p<0 .0 5 )。5℃时 ,Ik 值平均为 96μE/ (m2 · s) ,10℃时为 71μE/ (m2 · s) ,15℃时为 31μE/ (m2 · s)。呼吸速率 R值在 5℃时最低 ,为 5 4μmol O2 / (g DW·h) ,10℃、15℃和围隔中均高于 5℃时的呼吸速率 ,并且在 10℃达到最高。本次实验研究得出的生长和光合作用参数将有助于合理确定桑沟湾中海带的养殖容量。
This work is based on an EU project which intends to conduct research work on the carrying capacity for aquaculture and environmental in two semi-enclosed and shallow bays in North China, Jiaozhou Bay and Sanggou Bay. Sanggou Bay is located at 37°01′~37°09′N, 122°2′~122°35′E with an area of about 133km~2, which is fully exploited by aquaculture activities, and 1/3 of the total surface is dedicated to the culture of kelp and shellfish. Kelp grows on ropes in the field from October to April-May. Kelp yield re...
