Problems solved by technology

Copper algae plants are tall, with luxuriant branches. They grow on the shallow sea rocks beyond the dry tide line and float in pieces on the water surface. They are called "sea forests" and are one of the preferred species for marine ecological environment restoration. artificial breeding technology is in the initial stage of development

Embodiment Construction

[0005] 1. Collect seedlings: Copper algae are dioecious. Under natural conditions, in the first half of each year, before June, when the water temperature in the sea area is 13-18°C, it is the peak growth period of copper algae sporophytes. When the water temperature in the sea area rises to about 15°C and the reproductive receptacle of the copper algae gradually matures, the mature and complete algal bodies can be collected in time as seedlings, and the ratio of the number of male to female plants is 2:1.

[0006] 2. Indoor cultivation: Seedlings are moved into the nursery for indoor cultivation. Clamp the seedlings in the seedling rope, such as vinylon rope, and place them on the water surface in the nursery pond. The control parameters in the pond are: the depth of the pond is 40-80cm, the water temperature is 18-24°C (increase by 1°C every 5 days), and the light intensity is 1500-5000Lux , the salinity is 29-31‰, and the daily water change is 10-20%. Cultivate until the f...

Abstract

The invention relates to the artificial breeding technique of sargassum horneri, belonging to the technical field of the fingerlings of algae. The artificial breeding is implemented by the four stages of seedling collection, indoor cultivation, artificial seeding and indoor culture. The invention has the advantages of easy mastery of the technique, small investment simple facilities and other advantages.

Description

technical field [0001] The invention belongs to the technical field of algae seedlings, in particular to the artificial seedling cultivation technology of copper algae Sargassum horneri (Turn.) Ag. Background technique [0002] Copper algae is a large brown algae discontinuously distributed along the coast of my country, and it is a unique warm temperate seaweed in the western North Pacific Ocean. Copper algae is a high-quality raw material for the seaweed industry. It is widely used in medicine, food, feed and organic fertilizers, and has high commodity value. Copper algae plants are tall, with luxuriant branches. They grow on the shallow sea rocks beyond the dry tide line and float in pieces on the water surface. They are called "sea forests" and are one of the preferred species for marine ecological environment restoration. The artificial breeding technology is in the initial stage of development. Contents of the invention [0003] The purpose of the present invention...
