Porphyra conchospore seeding collection and net-attachment system and seeding collection method thereof

Abstract

The invention provides a porphyra conchospore seeding collection and net-attachment system and a seeding collection method thereof. The porphyra conchospore seeding collection and net-attachment system comprises a collection device, the collection device comprises a collection ship and an automatic conveying device, the collection ship is provided with at least one collection barrel and a cabin, the collection barrels are installed in the cabin, and shells are placed in the collection barrels; the automatic conveying device is communicated with the collection barrels and the outside, the automatic conveying device comprises a water inlet pump and a water outlet pump, the water inlet pump conveys sea water to the collection barrels to stimulate shell conchospores disperse, and the water outlet pump discharges water of the conchospores in the collection barrels to a net curtain. Therefore, porphyra haitanensis all-floating culture and offshore intensive seeding collection are achieved through an automatic seeding collection and net-attachment technology, and technical support is provided for popularization of a novel ecological and efficient porphyra haitanensis culture mode.

Description

technical field [0001] The invention relates to the technical field of algae seedling collection, in particular to a net-attached system for collecting seedlings of laver conchospores and the seedling picking system. Background technique [0002] Altar seaweed (Pyropia haitanensis) belongs to Rhodophyta, Rhodophyceae, Rubiaceae, Rubiaceae, Porphyra, it is delicious, nutritious, rich in a variety of amino acids, vitamins and trace elements necessary for the human body , so it is very popular. Porphyra laver is a unique variety of laver in my country. The cultivation area spans Fujian, Zhejiang and Guangdong, and its output accounts for more than 75% of the national laver production. [0003] At present, there are three main cultivation methods of altar laver in the country: pillar type, semi-floating raft type, and full-floating raft type. Pillar farming is to fix the net curtain on the pile wood, which cannot rise and fall with the tide, and is easily affected by wind, wav...

AI Technical Summary

Problems solved by technology

[0004] One of the factors affecting the success of full floating cultivation of algae laver is that the net curtains are poor in seedling picking, and the management in the later stage cannot keep up, which leads to the inconspicuous cultivation benefits, which affects the economic benefits of cultivation

The full-floating flow net curtain picking is the same as the traditional rod-inserting (or pillar) seedling picking method. Due to the long time of picking seedlings and hanging on the net, the conchospores are lost and dead, which affects the effect of full floating flow cultivation.
