Problems solved by technology

However, at present, the cost of obtaining the attachment base with suitable specifications in batches is relatively high.
[0005] (2) The single shells laid flat on the bottom of the pool in the traditional cultivation method lack efficient cleaning management methods
The shell attachment base needs to be regularly washed and managed to remove the algae on the surface of the attachment base during the filament cultivation stage. Due to the limited area of ​​the single shell, in order to meet the production needs, the amount of single shell is huge, and the current cleaning method is difficult to completely remove the surface of the attachment base. Algae, easy to cause algae cross-contamination
[0006] (3) The deployment of the shell attachment base has the problem of high labor cost consumption
In the traditional cultivation method, after the cleaning of the shell attachment base is completed, the cleaned shells need to be evenly and neatly placed on the bottom of the pool, and the filaments on the shells are not resistant to drying out, so the shell attachment base layout needs to be done in a short time. It needs to be completed within a short time, which requires the cooperation of many skilled workers, and the cleaning of shells is mainly done manually by manpower, which requires a lot of labor costs
In addition, during the cultivation process, uneven illumination at each corner of the cultivation pond will lead to asynchronous growth of the filaments on the shells. At this time, it is necessary to adjust the location of the shell attachment base in the cultivation pond in time. Position adjustment also depends on manpower

Abstract

The invention discloses an adhesion substrate for artificial cultivation of porphyra yezoensis conchocelis. The adhesion substrate comprises a cement base, oyster shells, and auxiliary handles; the cement base main body is made of cement; the oyster shells are closely connected and distributed on the adhesion substrate; a surface with a pearl layer of each oyster shell faces upwards; the rough surface of each shell is embedded into the cement base; the auxiliary handle is embedded into the cement base; and two ends of the cement base are respectively provided with one auxiliary handle, and themain function is to assist the movement and distribution of the adhesion substrate. A mode of integration and fixing of the shells is adopted in the application, the size and specification limitationof raw materials of adhesion substrates is broken through, and the utilization rate of the shells is improved. The adhesion substrate with the cement base can be cleaned with the match of high-pressure water-flow washing, meanwhile, displacement of the adhesion substrate is avoided, and the cleaning efficiency is improved, so that the labor cost is reduced. The utilization area of a single adhesion substrate is effectively increased; and compared with the area of conventional adhesion substrates, the area is increased by 15-30 times, so that the breeding efficiency is remarkably improved, andthe production management cost is reduced.

Description

technical field [0001] The invention relates to the preparation and use method of an attachment base suitable for cultivating Porphyra zebra filaments, in particular to the preparation and use method of an attachment base for artificial cultivation of Porphyra zebra filaments, belonging to the field of seaweed cultivation. Background technique [0002] Porphyra zebra is a kind of red algae with high economic value, its output value accounts for about half of the total output value of laver, and it is mainly cultivated in northern my country. Porphyra variegata has a long history of artificial cultivation. Since 1970, Porphyra variegata has been successfully cultivated in the northern coastal areas, and the artificial seedling cultivation and cultivation technology system of Porphyra variegata has been gradually established and improved. Porphyra zebra can generally be divided into two different generations: fronds and filaments. The attachment base for artificial cultivation...
