摘要
裙带菜藻体较大,是一种味道鲜美的食用海藻,浙江称“海芥菜”。由于生长期短,在冬季及早春生产,这种藻类既适于生鲜食用,也可以加工制成干品。我国北方冬季主要依靠几种秋菜的储藏,缺乏足够的新鲜蔬菜,而这期间,正是裙带菜嫩菜生产的季节,因此,生产裙带菜来增添冬季蔬菜的种类,对改善人民生活有着一定的意义。裙带菜广泛地分布在我国东海及黄海沿岸。多年以前,在大连和青岛就曾经进行过大量的投石增殖这种海藻,但迄今亦尚未进行全人工养殖。在一些不适于海带养殖的海区,裙带菜可能是一种很好的养殖对象。
1.Rapid growth of Undaria pinnatifida(Harv.)Sur.occurs at 5-15℃which is regarded as the favorable temperature for its growth.When the length of lamina is over 60 cm rapid growth also occurs even at a lower temperature.So the effect of tempera-ture on growth is different at different frondal lengths.2.The favorable temperature for development of sporangia is 10-20℃.Below 10℃,the large Undaria frond may develop and a little above 20℃,the little one de-velops may also develop.Thus the temperature for development is associated with the length of fronds.3.On the basis of the results of this experiment,it was suggested that:1)at Tsingtao,as well as at other places along the North China coast,cultivation of first crop of the Undaria by artificial method may be made from November to Feb-ruary when the temperature drops from 10℃to 0℃and then rises up to 3℃,and from March to June when the temperature rises from 3℃to 15℃cultivation of second crop may be effected.2)because of the short-growing period of Undaria,the method of cultivation may be varied,and cultivation may be effected between the rows of the raft of Laminaria.3)owing to the fact that the smaller fronds of Undaria develop sporangia at higher temperature,it seems desirable to cultivate special late maturation strains of this Undaria in the months of July and early August.
