Embodiment Construction

[0005] 1. When the natural water temperature in the sea area is 26-28° C. (in September every year), utilize the existing technology to pick altar laver spore seedlings behind the net curtain and grow them in the sea. After the 4th or 5th harvest is completed, when the natural water temperature in the sea area drops to 13-15°C (in late December every year), the breeding is terminated and the net curtain is withdrawn.

[0006] 2. When the natural water temperature in the sea area is 22-23°C (from mid-October to early November every year), the concospore seedlings of Porphyra variegata are collected and refrigerated behind the net curtain for later use.

[0007] 3. After the altar laver cultivation is completed, the refrigerated net curtain can be put into the sea by using the existing technology, sea area and cultivation racks to grow Porphyra variegata. Breeding until early March of the following year, about 3-5 harvests can be completed.

Abstract

The present invention relates to algae cultivating technology, and is especially the method of cultivating Porphyra haitanensis and Porphyra yezoensis alternately in the laver cultivating area. The method can raise the utilization of cultivation area and cultivation apparatus and raise production.

Description

technical field [0001] The invention relates to seaweed cultivation technology, in particular to a method for rotation cultivation of algae laver and laver laver. technical background [0002] Altar seaweed is a warm-temperate species, and it is the main seaweed culture species in the East my country Sea region of China. The main production areas are the coasts of Zhejiang and Fujian. Porphyra zebra is a cold-temperate species, and it is the main species of seaweed cultured in the Yellow and Bohai Sea regions of my country. The main production areas are the coastal areas of Jiangsu and Shandong. At present, a single species is cultivated in all sea areas, and there are three defects: ①The utilization rate of sea areas and breeding facilities is not high; ②The yield per mu is low; ③The time to provide raw materials for the processing link is too short. Contents of the invention [0003] The purpose of the present invention is...
