Embodiment 1

[0014] For cultivation: as shown in Figure 2, the light-weight anti-wind and wave laver cultivation raft is set in the intertidal zone, and the floating bamboo and the net are arranged alternately, with a structure of 3 legs; The method is replaced with the side rope 2 of net curtain 6, and the stake cable 1 at both ends is a single structure, with the polypropylene rope of diameter 1.2~1.4cm, depends on the size of wind and waves (the diameter of present embodiment adopts the polypropylene rope of 1.2cm). Propylene rope), the floating bamboo diameter is 4~5cm (the present embodiment diameter is 5cm), and the floating bamboo spacing is 4m; Supporting leg structure is the same as conventional raft frame.

[0015] When this embodiment is used for cultivation, 6 single-layer net curtains are used to hang, to reduce the resistance of wind and waves with light weight to improve the wind and wave resistance performance, and it is far lighter than the traditional raft frame during app...

Embodiment 2

[0017] For raising seedlings: with the pile cable rope of embodiment 1 light-duty anti-storm laver cultivation raft frame, the floating bamboo diameter, the floating bamboo spacing difference are: the pile cable 1 at two ends uses the polyethylene rope of diameter 1.4cm, and floating bamboo diameter is 4cm, and floating bamboo The spacing is 6m, and the net curtains are overlapped and hung during the seedling raising period;

[0018] In this embodiment, the number of layers of the net curtain 6 can be 6 to 18 layers when it is used for seedling cultivation, especially with 6 to 12 layers of net curtains overlapped and hung, the effect is very good, and 8 batches of 30 mu of laver seedling nets have emerged. The density has all reached the standard of high-quality seedling nets. The production operation of the seedling raising is the same as that of the conventional seedling raising raft, but it is far lighter than the conventional seedling raising raft (the material cost is on...

Abstract

The light wind wave resisting laver culturing rafts without side cable are set intertidal zone and are connected with nets. The light wind wave resisting laver culturing rafts have single pile cable structure with cable of polypropylene or polyethylene and floating bamboos of 4-5 cm diameter and 4-6 m interval. The light structure has reduced wind wave resistance and raised wind wave resisting performance, and the single pile cable makes the raft turnable for mechanical collecting. Compared with available raft structure, the present invention is light, low in cost, easy in operation, high in wind wave resistance and suitable for mechanical collecting.

Description

technical field [0001] The invention relates to a laver cultivation technology, in particular to a light-weight anti-wind and wave laver cultivation raft and its application. Background technique [0002] For a long time, my country's seaweed cultivation industry has mainly developed in the intertidal sea area, with a total area of ​​more than 20,000 hectares (300,000 mu) of cultivation, and a square-shaped frame structure raft is generally used (see Figure 1). , installed in the intertidal zone, the two pile cables 1 at both ends are connected with the side cables 5 on both sides, using polypropylene or polyethylene ropes with a diameter of 1.6 to 2.2 cm, the diameter of the floating bamboo 4 is 6 to 10 cm, and the spacing is 2 to 4 m. The two ends of 4 are bound with supporting legs 3 to form a complete frame raft structure. Generally speaking, the equipment used is too bulky, the resistance in the wind and waves is huge, the work at sea is difficult, and the cost of materi...
