海带筏间养殖裙带菜的试验

EXPERIMENTS ON INTERCULTURE OF UNDARIA PINNATIFIDA(HARV)SUR.WITH LAMINARIA JAPONICA ARSCH

摘要:

裙带菜的室内水池简易育苗获得成功后,生产苗种的技术基本可以满足养殖生产的要求,目前,如何提高裙带菜的养殖技术就成为需要解决的重要课题。根据裙带菜孢子体的生长、发育与温度的关系的研究中提出:裙带菜的养殖方式可以采用与生长期长及养殖期较长的藻类配合进行间作来生产裙带菜的嫩菜,也可以采用裙带荣的成菜与嫩菜轮养或者连养两茬成菜等方式,开展海面筏式全人工养殖。裙带菜虽然是一种鲜美的食用海藻,但我国人民除朝鲜族和北方沿海个别地区外还没有食用的习惯。所以在开展裙带菜的养殖事业中先采取与海带间养作为海带养殖的副业进行经营,我们认为这是一条切实可行的途径。因此,裙带菜的养殖应该尽先研究间作的技术。

Abstract:

1.Experiments were conducted at Shantung Marine Cultivation Station, 1963,on the interculture of Undaria pinnatifida(Harv.)Sur.on the bamboo rafts used primarily for the cultivation of Laminaria japonica Arsch.It was proved that the method of interculture was successful in the increase of pro- duction. 2.It was reported that for a short period of 60 days'interculture,the influence to Laminaria's growth was very slight and temporary,and it was possible to produce 850 kgs.of Undaria,about equivalent to 17% of Laminaria per mou. 3.In the event of extending the intercultural period to 80 days,the yield of Undaria could be increased to 1,000～1,200 kgs.,about equivalent to 20～24% of Laminaria per mou.Although the extension of time somewhat hindered the growth of Laminaria,yet one month after the harvest of Undaria, normal growth would soon be recovered. 4.It was concluded that the intercultural method provided a favorable means for developing commercial cultivation of Undaria,inasmuch as its ex- clusive culture was not considered to be economical.
