Laver breeding method

Abstract

The invention discloses a laver breeding method, which includes the following steps: (10) fixing floating balls on cross rods to form floating ball carriers; (20) arranging a plurality of floating ball carriers transversely along the length direction of a breeding net; (30) in a pair of cables, respectively tying, by a first cable and a second cable, with a front floating ball carrier, and tying the free ends of the two cables together to form a first connection knot; and in other pair of cables, respectively tying, by a first cable and a second cable, with a rear floating ball carrier, and tying the free ends of the two cables together to form a second connection knot; (40) respectively connecting two third cables with the first and second connection knots; (50) planting laver seedlings in the breeding net; (60) respectively fixing the free ends of the two third cables on front and rear column piles, with the floating ball carriers on the upper side and the breeding net on the lower side; and (70) during the breeding period, hooking and lifting the distal ends of the cross rods of the front or rear floating ball carriers to one side of people by manually adopting a pull rod on oneside of the breeding net every day, so as to enable the floating ball carriers to rotate to turn over the breeding net to expose the laver seedlings to sunlight for a certain period of time.

Description

technical field [0001] The invention belongs to cultivation of laver, and relates to a method of cultivating laver, more specifically, it is a method that can realize the flipping of the cultivation net by operating the floating ball, so that the laver can dry out and carry out photosynthesis at the same time. Background technique [0002] Seaweed, as an economic crop, is favored by consumers for its delicious taste, rich in protein and various elements needed by the human body. In recent years, a large number of tidal flats have been continuously reduced due to engineering construction, and grid farming in shallow sea areas has become more and more respected by people. [0003] In seaweed cultivation, seaweed seedlings need to be continuously soaked in seawater and dried out of sea level to receive sunlight, which makes large-scale grid cultivation of seaweed very hard and troublesome. In particular, the labor intensity of workers is high when the grid is pulled back to the...

Problems solved by technology

[0003] In seaweed cultivation, seaweed seedlings need to be continuously soaked in seawater and dried out of sea level to receive sunlight, which makes large-scale grid cultivation of seaweed very hard and troublesome. In particular, the labor intensity of workers is high when the grid is pulled back to the land to be exposed to the sun. It takes a long time and is very inefficient

[0004] With the development of the economy and the advancement of technology, people try to use the power mechanism to drive the adjustment rod through the pull rope, and let the adjustment rod drive the floating ball to rotate to control the ups and downs of the grid. This method can reduce a lot of labor, but it will greatly increase The cost of farming, and the mechanism is prone to failure in wind and waves, which increases the maintenance cost of the mechanism
