浙江省象山港紫菜轮栽及其品质分析的研究

STUDY ON ROTATION CULTURE OF LAVER AND THEIR QUALITY ANALYSIS IN XIANGSHANGANG OF ZHEJIANG PROVINCE

作者在浙江省象山港进行了紫菜的轮栽试验以及条斑紫菜的品质分析。由于浙江省是坛紫菜的北限海域，条斑紫菜的南限海域，对轮栽具有地域上优势，试验结果亩产可达１０３．２ｋｇ。通过对条斑紫菜的光合作用色素、粗蛋白、游离氨基酸、全糖、游离糖等含量的测定和综合分析认为质量偏低。试验结果表明，象山港轮栽的条斑紫菜产高质次，品质改善有待于进一步试验和研究。

It is shown by the experiments that Xiangshangang has the geographical advantage in the lavers cultue, for it is the most northrn culture ground for Porphyra haitanensis and the most southern culture groundfor P.yezoensis. Rotation culture does not only increase the output but also improve the utilization ratio of processing machine. So the economic benefits can be increased. According to the analysis of variations in contents of photosynthetic pigments, crude protein, total sugars, free amino acids and free sugars, it is concluded that dried laver of Xiangshangang is not of high-quality. So its quality need to be further improved.
