Abstract

The invention provides a sinking and floating seaweed cultivating device. The device comprises a cultivating net screen and a floating rope or an edge rope. The device is characterized in that the device also comprises a desiccation device; the desiccation device comprises a column; an upper floater, a lower floater and a sinker are respectively arranged on the column from top to bottom; the sinker is connected with the lower end of the column via a rope; the floating rope or edge rope is connected on the upper part or the upper floater of the column; and the cultivating net screen is connected on the floating rope or edge rope via the rope. The device has more reasonable structure, is convenient to use, is hardly limited by water depth and is suitable for wider offshore areas, especially the deepwater gulfs away from wind. The device adopts the natural tidal range for desiccation, is beneficial to mechanical harvesting and has good capability of resisting wind and waves. Popularization and application of the device give a great push to the development of the coastal seaweed cultivation industry in China.

Description

technical field [0001] The invention relates to a cultivation device suitable for laver in deep water areas, in particular to a floating laver cultivation device. Background technique [0002] Porphyra belongs to intertidal organisms, in order to exclude other competitors, it needs to be dried frequently. Porphyra cultivation can be carried out in intertidal or subtidal zones. Aquaculture in the subtidal zone is faced with the problem of artificial drying. At present, the most commonly used method is the rod insertion type, also known as the pillar type, which is to insert bamboo poles on the seabed, hang the net curtain on it, and adjust the appropriate height, so that the net curtain floats on the water surface at high tide and dries out at low tide. . At present, the commonly used moso bamboo has a diameter of 10-14cm and an available length of 10-14m. Since the tidal range is 4-5m, moso bamboo needs to be inserted into the seabed by 1-2m, so the water depth of the pl...
