Vertical seedling device of laver shell conchocelis and application method thereof

Abstract

The invention discloses a vertical seedling device of laver shell conchocelis. The device comprises a seedling pond, a hanging rod of which the direction is identical to the water flow direction of circulating water is arranged on the top of the seedling pond in an erected mode, and multiple strands of shells which are inoculated with carpospores or conchocelis are hung on the hanging rod; a transparent plastic pipe which is distributed in an S-shaped mode, is parallel to the hanging rod in the vertical direction and is prevented from being corroded by sea water is fixed to the bottom of the seedling pond, and the transparent plastic pipe and the hanging rod are arrayed at intervals; two ends of the transparent plastic pipe are connected with a power supply and a control pile which are notin contact with sea water, a plurality of wires penetrate through the transparent plastic pipe in an insertion mode, a plurality of LED lamps are in serial connection with the wires, the wires are connected with a light time controller in the control pipe, and a separate switch is arranged on the control pile, of each wire. The vertical seedling device of laver shell conchocelis is simple in structure, the using method is simple and easy to operate, the step of manual shell replacement is omitted, meanwhile, the device is suitable for porphyra haitanensis and porphyra yezoensis, the requiredarea of a seedling room can be decreased by dozens of times, and the land resource is greatly saved.

Description

technical field [0001] The invention belongs to the technical field of laver cultivation, and in particular relates to a vertical seedling cultivation device for laver shell filaments and an application method thereof. Background technique [0002] Porphyra is the largest large-scale economic seaweed in my country. According to the statistics of "China Fishery Statistical Yearbook", it is about 900,000 mu. The types of laver cultivated in my country mainly include altar laver and zebra. The scale of altar laver cultivation is about 300,000 mu, and the scale of laver cultivation is about 600,000 mu. Altar laver is a warm-temperate species, mainly cultivated in Fujian and Zhejiang, and Guangdong also has a certain scale of cultivation. Porphyra zebra is a cold-temperate species, which is mainly cultivated in Jiangsu Province, and there is also small-scale cultivation in Rizhao, Shandong Province. Due to the warming of the climate, in recent years, algae laver has tried to mo...
