Embodiment 1

[0039] A method for synchronously drying altar laver, comprising the following steps:

[0040] (1) Construct a checkerboard-shaped rod frame:

[0041]Select the cultivation tidal level suitable for Porphyra laver, and arrange the inserting rods 3 in rows from the high tide level to the low tide level, consistent with the direction of seawater flow; Looking down, it forms a checkerboard shape; on the outer beach surface of the outermost insertion rods of the rows of insertion rods, a plurality of adjustment piles 1 are set up, and the adjustment piles correspond to the insertion rods one by one;

[0042] A quarter of the upper part of the insertion rod is fixed with a suspension ring 8, which is a movable pulley;

[0043] The distance between the inserted rods in a row is 2.8 to 3.3 times the length of the struts;

[0044] The distance between the inserted rods in a row is 1.1 to 1.3 times the length of the struts;

[0045] There are 20 inserting rods in each column, 10 in e...

[0062] A method for synchronously drying altar laver, comprising the following steps:

[0063] (1) Construct a checkerboard-shaped rod frame:

[0064] Select the cultivation tidal level suitable for Porphyra laver, and arrange the inserting rods 3 in rows from the high tide level to the low tide level, consistent with the direction of seawater flow; Looking down, it forms a checkerboard shape; on the outer beach surface of the outermost insertion rods of the rows of insertion rods, a plurality of adjustment piles 1 are set up, and the adjustment piles correspond to the insertion rods one by one;

[0065] A quarter of the upper part of the insertion rod is fixed with a suspension ring 8, which is a movable pulley;

[0066] The distance between the inserted rods in a row is 2.8 to 3.3 times the length of the struts;

[0067] The distance between the inserted rods in a row is 1.1 to 1.3 times the length of the struts;

[0068] There are 18 inserting rods in each column, 8 in e...

Abstract

The invention discloses an inserted-bar type synchronous dry-out method for porphyra haitanensis. Suspension rings are added to the places where stay bars, inserted bars and lifting ropes are connected, and the lifting ropes can slide freely relative to the stay bars and the inserted bars, so that a linkage type sliding device is formed; when observed from the side face, each lifting rope is in vertical serial connection between the corresponding inserted bars and the corresponding stay bars and can slide freely, therefore when the web position height is adjusted, adjustment of the height of each whole row of web curtain can be completed by only retracting or extending one end of the corresponding lifting rope, and particularly when the lifting ropes are operated during rising tide, simpleness is achieved, and labor intensity is low; due to the fact that a whole raft rack is consistent in material, growth of porphyra haitanensis is basically synchronous, from the mechanical angle, the suspension rings of the identical inserted bars and stay bars are the same in stress, only the lifting rope at one end is tightened or loosened, time control over synchronous water-in and dry-out can be achieved, the dry-out and water-in time can be controlled artificially, and synchronism is good; by means of a device adopted according to the method, the structure of culture facility is slightly changed, investment is small, cultured laver is good in quality and high in output, and production benefits are remarkably increased.

Description

technical field [0001] The invention relates to a method for drying algae laver, in particular to a method for synchronously drying algae laver by inserting rods, and belongs to the technical field of seaweed breeding. Background technique [0002] my country's altar laver cultivation area exceeds 300,000 mu, and has become an important source of income for coastal fishermen. Porphyra naturally grows on intertidal reefs, that is, when the tide is high, it is submerged in sea water, and after low tide, it is exposed to the air. Drying out has a very important effect on the growth of laver, removing diseased and rotten cells in time, and reducing the adhesion of algae hazards and improve penetration resistance. Therefore, when Porphyra is introduced into artificial cultivation, it is necessary to adjust the space position of the cultivation raft and the cultivation net curtain in time according to the different physiological conditions and climate changes of Porphyra, and adj...
