Porphyra haitanensis shell conchocelis ripening and seedling collecting method

Abstract

The invention aims at providing a porphyra haitanensis shell conchocelis ripening and seedling collecting method. The method comprises the following steps: (1) cultivating shell conchocelis before ripening, (2) ripening shell conchocelis, (3) synchronously diffusing conchospore and (4) collecting the conchospore. The porphyra haitanensis shell conchocelis ripening and seedling collecting method is simple to operate, shortens the transportation process, and can produce the spatfall porphyra haitanensis with good quality. Therefore, the production mode of improving synchronous diffusion of the porphyra haitanensis conchospore becomes an approach of relieving seedling cultivation and seedling collection of the porphyra haitanensis with good quality and reducing seedling cultivation cost. The porphyra haitanensis shell conchocelis ripening and seedling collecting method is simple and practicable and good in effect. Compared with the traditional technology, labor strength is reduced, working procedures are reduced, the quality of the porphyra haitanensis spore is good, and production efficiency is obvious.

Description

technical field [0001] The invention belongs to the technical field of algae genetics and breeding, and in particular relates to a method for promoting ripening and collecting seedlings of algae shell filaments. Background technique [0002] Altar seaweed, as a kind of edible large seaweed, not only has high protein content (generally about 34%) but also rich vitamin content, and also contains a variety of amino acids and mineral nutrients, which have good effects on preventing heart disease, cancer, constipation, and lowering cholesterol. Features. [0003] In the past 40 years, due to the improvement and popularization of artificial seedling breeding technology, the rapid development of algae laver breeding industry has been promoted. In particular, the method of inoculating shells with fruit spores and free filaments, cultivating shell filaments, promoting ripening, releasing conchospores, and obtaining seedlings has obvious advantages, and this technology has been widel...

Problems solved by technology

[0006] However, the synchronous release of Porphyra laver in the natural state is generally completed during the high tide. In order to promote the synchronous release of conchospores, people often place the shell filaments in the sea, and realize the synchronous release through the dynamic stimulation of the tide. Often such Operation takes 2-4 days

In order to disperse synchronously, the traditional method is to carry out the repeated work of "exiting shell filaments from the warehouse-transporting-stimulating the sea area overnight-transporting-collecting seedlings-changing water" every day, purely to promote synchronous dispersal and cannot produce Any benefit, and it needs to be transported from land to offshore, from indoor to sea, which is labor-intensive, and shells are prone to drying out and damage during transportation, which affects the release of conchospores and the growth of seedlings, and the conchospores cannot be concentrated Dispersion, quality and other issues, seedling farmers often attribute the reasons to the climate or sea area
