Embodiment Construction

[0024] Select the algae, and collect the algae in the intertidal zone of the natural sea area at the mature stage of the algae, and select the algae with obvious growth, uniform thickness, moderate length, bright color, strong algae, and just emerging reproductive trays as the adult. Algae, put it in the indoor holding pool in advance for holding temporarily.

[0025] For algae clipping, choose polyethylene fiber blended rope, all of which are made of three strands, with a diameter of 8-10mm, suitable for tightness, and a length of 2m. There are 2-4 seedlings in each cluster, and the distance between clusters is 5-10cm. There are 18-20 clusters of seedlings per rope. Soak the seedling rope in seawater before clamping the seedlings, so that the seedling rope is in a moist state.

[0026] Select the temporary breeding pond, use the cultivation pond or other ponds in the abalone nursery workshop or bait cultivation workshop, the cultivation workshop requires natural light, and t...

Abstract

The present invention provides a sargassum thunbergii seed-vegetable artificial-ripening condition controlling method, which can resolve the problems that the maturation of the male seed vegetable and the female seed vegetable is not synchronous and the developing time of the homosexual seed sargassum thunbergii in the sexual reproduction breeding process. The present invention uses the conditions that can be artificially controlled to achieve the artificial ripening of the seed vegetable in the seedling breeding process and can provide an excellent-quality seed vegetable for the seedling of the sargassum thunbergii. The technical proposal of the present invention comprises the selection of the adult sargassum thunbergii, gripping of the adult sargassum thunbergii, the selection of the temporary-cultivation pool and the controlling of the conditions for cultivation. Adopting the method of the present invention, the lighting time on the adult sargassum thunbergii is prolonged, the lighting strength is increased, the influence of the severe environment on the frond is reduced, the maturation of the pyrenium is relatively concentrated, the maturation of the male and the female pyrenium becomes synchronous and a plenty of concentrated fertilized eggs are achieved, which is beneficial for the success of the one-off seedling collection.

Description

technical field [0001] The invention relates to a method for controlling artificial ripening conditions for growing seaweed vegetables, in particular to a control method for artificially promoting ripening conditions for growing sargassum vegetables. Background technique [0002] Sargassum is a common wild species of brown algae in the coast of my country. In my country, it is distributed from the Liaodong Peninsula in the north to the Leizhou Peninsula in the south. Its traces are all over Liaoning, Shandong, Jiangsu, Zhejiang, Fujian, Guangdong and other provinces. With the deepening of its research in recent years, some important functions of Sargassum have been gradually discovered: in addition to occupying an important position in the marine ecosystem, it also has many possibilities in medicine, health care, aquaculture, chemical industry, and food industry. development potential. [0003] Sargassum is rich in polysaccharides, and is often used as an immune enhancer in...
