Embodiment 1

[0029] A method for large-scale cultivation of copper algae based on nutrient rapid propagation of the present invention comprises the following steps:

[0030] (1) Test site

[0031] The test sea area is the sea area of ​​Shanhaitian Tourist Resort, Quangouzi Village, Liangcheng Street, Rizhao City, Shandong Province. The seawater depth in this area is about 18m, which is shallow sea, without industrial pollution and a large amount of fresh water, with few predatory organisms, seawater transparency of 0.8m, and water flow. The speed is about 40cm / s, the salinity is 31-35‰, the wind and waves in this sea area are small, the sediment is sandy and muddy, the bottom is stable, the tide is smooth, and the minimum temperature in winter is not lower than 2℃.

[0032] (2) Collection and transportation of copper algae vegetables

[0033] On November 10, 2015, floating copper algae were collected in the sea area of ​​Lidao Town, Rongcheng City, Shandong Province as a cultured seed. Th...

Abstract

The invention discloses a scaled cultivation method of sargassum horneri based on nutrient rapid propagation and belongs to the technical field of seaweed breeding. The method comprises the following steps of: 1) selecting a cultivation sea region; 2) collecting sargassum horneri main weeds and transporting and collecting floating sargassum horneri and conveying the same to the cultivation sea region; 3) gripping and sea cultivation: gripping the sargassum horneri on seedling ropes and hanging the seedling ropes on a raft rack; 4) daily management and harvesting: selecting the main weeds, then performing cultivation and harvesting; 5) main weed conservation and aestivation: continuously breeding and aestivating the main weeds in a region which is deep, large in flow and low in temperature; and 6) planting and cultivation of the main weeds again: continuously collecting the main weeds, gripping the same, and cultivating the same to obtain the main weeds and harvesting the sargassum horneri. The method for vegetative propagation by means of nutritional branches of the floating sargassum horneri has the characteristic of yearly growth, sargassum horneri can be cultivated on a large scale conveniently and rapidly, and the method is simple to operate, time- and labor-saving and high in growing speed, is not limited by manure main weeds, a lot of main weeds can be cultivated anytime, a phenomenon of seedling elimination is avoided, and the survival rate is high.

Description

technical field [0001] The invention belongs to the technical field of copper algae cultivation, in particular to a large-scale cultivation method of copper algae based on nutrient rapid propagation. Background technique [0002] The copper alga Sargassum horneri belongs to the genus Sargassum, with tall algae plants and luxuriant branches and leaves. It is an important part of the offshore marine ecological environment. It can not only provide foraging and habitat for economic fish, but also absorb eutrophic substances in seawater. As a tool for restoring the offshore ecological environment, seaweed is an important economic brown algae. In recent years, with the gradual deepening of research on it, the bioactive substances such as alginate, fucoxanthin, dietary fiber and polysaccharide rich in copper algae have attracted widespread attention at home and abroad, and have been widely used in medicine and food. , feed and organic fertilizers. With the development and utiliza...
