Description

Folding type laver culturing device

Technical Field

The invention belongs to the technical field of aquaculture, and particularly relates to a folding type laver culture device.

Background

With the continuous increase of offshore pollution, the culture strength is continuously enhanced, the sea reclamation is carried out according to the requirements of harbor construction, and the traditional culture on offshore mudflats is increasingly impossible. The laver cultivation mode is also developed from intertidal zone semi-floating laver cultivation to inserted rod laver cultivation due to the change of cultivation environment.

At present, common laver culture methods mainly include an inserted-rod floating raft type, a semi-floating raft type and a turnover type.

The insertion rod float raft type cultivation is that a net curtain is hung between mao bamboos deeply inserted into a sea area, the net curtain can float up and down within a certain range along with the rise and fall of tides, but the labor intensity of the insertion rod is high, a large amount of mao bamboos need to be consumed, the cost is high, the environment protection is not facilitated, in addition, the cultivation area is limited, and the influence of stormy waves, tides and the like is easily caused. Meanwhile, since the laver needs to be sunned when growing, the laver needs to be pulled up at intervals, which wastes time and labor.

Semi-floating raft culture is that a raft frame floats on the sea surface when tide rises, and is exposed on a beach after tide falls off, so that the application range is very limited, once green algae harm occurs, a curtain needs to be disassembled and the raft frame needs to be transferred to the shore, the labor intensity is greatly increased, mechanical damage can be caused to laver, and the growth of the laver is influenced.

The turnover raft frame cultivation is to turn over the whole row of laver raft frames by means of the impact force of a ship or artificial measures, so as to realize the exposure, and the defects are that the loss of raft frame equipment and laver is overlarge. The present document thus provides a folding type laver culturing device for solving the above-mentioned problems.
