Embodiment 1

[0020] Such as figure 1 , 2 Shown in and 3; Breeding device comprises seedling rope, cover net and supporting processing device; Processing device is the hard cylinder segment of hard trumpet-shaped segment and two ends opening.

[0021] The small opening end of the hard trumpet-shaped opening section is connected with the hard cylinder section through a first fastener; the hard cylinder section 2 is installed at a height of 1.0-1.5 meters through at least one second fastener. on the base.

[0022] The total length of the hard trumpet-shaped opening segment and the uniform hard cylinder segment is 0.6-3.0 meters; the inner diameter of the hard cylinder is 200-400 mm, and both ends are open; the horn-shaped segment is open at both ends, large The inner diameter of one end of the opening is 400-600 millimeters, the inner diameter of one end of the small opening is consistent with the hard cylinder, and the vertical distance between the large opening and the small opening is 10...

Embodiment 2

[0030] In the processing device, the inner diameter of the large opening of the hard trumpet-shaped section is 400 mm, the inner diameter of the small opening is 200 mm, and the inner diameter of the cylindrical section is 200 mm. The middle is connected by a fastener steel hoop, and the base is 1.2 meters high.

[0031] The seedlings are Kappa longicardium, and the seedlings are divided to 100g / plant; the length of the seedling rope is 5 meters, and the distance between seedlings is 200 mm. The net mesh is 20 mm, the caliber is 300 mm, and the wire diameter is 0.1 mm.

[0032] Assemble 10 aquaculture facilities according to the assembly method of the above example, and fix them on the raft frame at the surface of the Sanggou Bay sea area in Rongcheng to realize artificial cultivation; continuous cultivation and observation for 20 days showed that the algae grew well, and no algae were observed due to water flow. Loss phenomenon, the fresh weight of harvested algae was 90 kg. ...

Abstract

The invention belongs to the field of red alga culture and particularly relates to an asparagus and kappaphycus alvarezii sinking-rope raft culture device and an assembling method. The culture device comprises seedling ropes, a cover net and a matched processing device. The processing device includes a hard horn-shaped open section and a hard cylindrical section with two open ends. A cover net protection part is added, achievement is promoted through a matched processing facility, asparagus and kappaphycus alvarezii plant loss in the culture process can be effectively reduced, an asparagus culture period can be prolonged, and culture benefits can be increased.

Description

technical field [0001] The invention belongs to the field of red algae cultivation, and in particular relates to a submerged rope raft culture device and an assembly method of asparagus and kappa. Background technique [0002] Asparagus and Kappa are important economical red algae for gum production. At present, the culture methods of the two kinds of seaweed are mainly based on the vegetative propagation characteristics of the budding mode, and the vegetative branches are used for propagation. The cultivation of asparagus requires a fixed site in the bay. After piling or anchoring, use a float to float the rope for clamping seedlings. Usually, 1 seedling is clamped at an interval of 200 mm. The length of the clamping rope depends on the layout of the sea area. 400-600 mm, both ends are fixed with bamboo poles or directly fixed on the kelp raft, when the vegetable body grows to 500-800 mm, it must be harvested in time, otherwise the vegetable body will be broken by strong w...
