Tidal range automatic drying cultivation method for laver culture

Abstract

The invention provides a tidal range automatic drying cultivation method for laver culture. The automatic drying cultivation method comprises a culture net field composed of multiple horizontal floating ropes and vertical floating ropes, and drying device sets and culture net sets are arranged between adjacent vertical floating ropes; each column of drying device sets is composed of multiple automatic drying devices, and each automatic drying device comprises a hollow pick-up rod and a floating rod; one ends of the hollow pick-up rods are perpendicularly connected with the middle portions of the floating rods, and a plurality of tail wings for stabilizing the hollow pick-up rods are evenly arranged at the other ends of the hollow pick-up rods in the peripheral direction of the rods; big floats are arranged on the hollow pick-up rods between the tail wings and the floating rods in a sleeving mode, inclined pull ropes are arranged between both ends of the big floats and the floating rods, and drying cables which can cooperate with the big floats to shoulder the floating rods are arranged in the hollow pick-up rods in a penetrating mode. According to the tidal range automatic drying cultivation method for laver culture, with the arrangement of the automatic drying devices, automatic drying and automatic water falling of the culture nets are achieved, and drying labor intensity is reduced; with the arrangement of the tail wings and the inclined pull ropes, the balance performance of the pick-up rods is improved; natural tides are fully utilized to achieve automatic drying of the laver culture net field, mechanized harvest is achieved, and the method can be used for culture in deep seas and open seas.

Description

[0001] This application is a divisional application with an application date of June 13, 2014, an application number of 201410262845.8, and an invention titled self-drying device for laver cultivation, cultivation device and tidal range self-drying method. technical field [0002] The invention relates to a laver cultivation technology, in particular to a tidal range self-drying cultivation method for laver cultivation. Background technique [0003] As coastal pollution continues to increase and expand, farming intensity continues to increase, nutrients are increasingly lacking, and laver blights are increasing. Coupled with the need for seaport construction, offshore farming has become increasingly impossible. From semi-floating seaweed cultivation in the intertidal zone, it has developed to pole-inserted laver cultivation; from the initial use of a pole of 7-8 meters, it has grown to 16-17 meters. However, the length and strength of the strut must be limited, which cannot ...

AI Technical Summary

Problems solved by technology

However, the length and strength of the struts must be limited, which cannot meet the needs of deeper sea areas.

[0004] The existing methods of fully floating raft culture laver include a "U" type full floating raft drying method, a tripod type full floating raft drying method and a flipping full floating raft drying method, and these methods have the following Defects in several aspects: first, the above-mentioned breeding methods all require manual operation, which is labor-intensive and difficult to operate at sea.

The manually operated drying device is only fixed on the buoy in the laver cultivation area. As the laver field floats as a whole, there is no connection and fixed control between itself and the seabed. Therefore, the impact load on the root cable of the laver field is heavy, and the resistance to wind and waves is poor. , the floating raft made by manual operation, when supporting the net curtain, only supports the two end points of the net curtain. The force on the two points of the floating raft is unstable, and it is easy to roll over or tilt under the impact of wind and waves. It is not suitable for use in sea areas with strong wind and waves. The device Its own wind and wave resistance is also poor; third, the work is not thorough

When the manual operation is done, the wind and waves will cause the device to be unstable. Therefore, the center of gravity of these devices must be lowered. Under the action of the waves, the laver will not be dried completely; fourth, the mechanized vegetable picking cannot be carried out, and the efficiency is low.

The above-mentioned manual operation is to dry out the full-floating laver cultivation method. The vegetable picking boat cannot enter under the net curtain to harvest laver, and it is blocked by the raft frame. Manual picking is required, which consumes a lot of labor and has low efficiency.

At the same time, it is difficult to control the length of laver on the net curtain after harvesting

When the vegetables are picked next time, they will be old and tender, which will affect the quality of laver; fifth, the manual operation of drying out the net curtain is one-time out of the water, and the load is heavy. High farming cost and low yield
