A kind of prefabricated seaweed seedling raising substrate and using method thereof

Abstract

The invention discloses an assembled laver seedling raising substrate and a using method thereof, belonging to the field of aquaculture. Includes shell fixing plate and fixing groove. Among them, the shell fixing plate is a rectangular cement plate prefabricated by foamed cement substrate; the fixing grooves are evenly distributed on the shell fixing plate, and its shape is adapted to the outer contour of the shell; The method is fixedly installed in the fixed groove, and when the next cycle is completed, the shell is removed and a new shell is replaced. In the present invention, the base plate of the assembled laver seedlings is used without destroying the parasitic growth base of the laver seed cells, and only the parasitic growth base shells of the original laver seed cells are embedded in the light and strong ceramsite foam by means of industrialization. On the cement substrate, it solves the problems of multiple times of loose assembly, bulk, cleaning, labor-intensive, time-consuming, and low efficiency in the traditional process, and the bolts are pre-embedded on the substrate, which solves the economic problem of only replacing the shells in a cycle without replacing the fixing plate. .

Description

technical field [0001] The invention belongs to the field of aquaculture, in particular to an assembled laver seedling-raising substrate and a method for using the same. Background technique [0002] Seaweed cultivation has been widely developed in the eastern coastal areas of my country. Its seaweed products are also deeply loved by consumers. The market is full of vitality, but the seedling raising process in the initial stage of seaweed cultivation is very cumbersome, inefficient, and backward in technology, which is far from meeting the market demand. It is an urgent problem to be solved today to develop a new seedling substrate that is not only ecologically friendly but also greatly improves the efficiency, and can also adapt to the ecological environment required for the development and growth of laver seedlings. [0003] The spore seeds of Porphyra are very tiny and can usually be observed under a microscope. In the marine environment, the spores of Porphyra organis...

AI Technical Summary

Problems solved by technology

[0004] After research by the applicant, it is found that the existing laver seedling raising process has the following problems and deficiencies: the traditional laver seedling raising process needs to artificially arrange the seed growth base shells in the seedling pond, and this labor process will be scattered and a large amount of The concentrated placement of shells will inevitably consume a lot of labor, and in the six months from the initial planting to the harvesting of seedlings, due to the need to clean the dirt on the surface of the shells, it is necessary to repeatedly cycle the shells from breaking up and reorganizing to breaking up and reassembling cycle (4~6 times)

Each single cycle consumes a lot of labor, and the cumulative labor consumption during the entire seedling growth period is even more

[0005] It can be seen that the current laver seedling cultivation process is complicated, backward, inefficient, and consumes too much labor. This is the problem and deficiency of the current laver seed seedling cultivation.
