Embodiment Construction

[0022] An acid treatment type laver full-floating culture method,

[0023] 1) Make acid

[0024] (1) The acid used is an organic acid, industrial waste acid is not allowed, formic acid or citric acid is generally used;

[0025] (2) Add about 10cm of seawater to the working boat, pour the acid into the seawater according to the mass ratio of 3%-10%, test the pH value of the acid solution with pH test paper, and adjust the pH value of the acid solution to 2.0-2.4;

[0026] (3) Due to the thin water quality in some sea areas, nitrogen or phosphorus fertilizers are added at a mass ratio of 5-30%;

[0027] 2) soaking or spraying

[0028] (1) Use the soaking method, the method is as follows: soak the laver net curtain into the acid solution for 8-10 seconds, and then put the net curtain into seawater for deacidification;

[0029] Or use the spray soaking method, the method is as follows: use laver acid treatment equipment to spray and soak the laver net curtain for 8-10 seconds; ...

Abstract

Provided is an acid treatment type full-floating laver culture method. According to the method, by the utilization of high desiccation tolerance of laver, organic acid is utilized, appropriate nitrogenous fertilizer or appropriate phosphate fertilizer is added, acid soaking or spraying soaking is carried out on a laver seedling net, then the effect for getting rid of wild seaweeds and diatoms is achieved, and the aim of being equal to physical drying out is achieved. Compared with an ordinary full-floating laver culture method, the acid treatment type full-floating laver culture method has the advantages that no wild seaweed erodes, the laver is free of the diatoms, the quality of the laver is high, and the growing period is long. Compared with an ordinary laver inserted rod type culture method, the acid treatment type full-floating laver culture method has the advantages that the productivity is higher by 20%, the harvesting intervals are short, and the working intensity is low. Compared with a semi-floating type laver culture method, the acid treatment type full-floating laver culture method has the advantages that the laver culture can be carried out in deep water areas, and the productivity is high.

Description

technical field [0001] The invention relates to a laver cultivation technology, in particular to an acid treatment type laver full-floating cultivation method. Background technique [0002] There are two main cultivation methods of seaweed cultivation, which are rod insertion type and semi-floating type. The specific features are as follows: [0003] Porphyra cultivation is also known as pillar-type raft cultivation. Porphyra is used to dry laver. Compared with full-floating cultivation, the cultivation water is deeply limited, only 3-8 meters; the quality is better. It is one of the current mainstream farming methods. [0004] Porphyra semi-floating culture, also known as semi-floating raft culture, refers to the cultivation of laver in the intertidal zone. It is characterized by floating on the water surface during high tide and drying out during ebb tide. The cultivation is limited by the area and location of the tidal flat, and the quality is better. It is one of the ...
