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.

[0050] In the course of further research, in order to prepare a reusable cement substrate. The present invention also provides a preparation method of an assembled seaweed seedling-raising substrate, which includes the following steps: designing a special concrete cover plate mold, and a plurality of shell-shaped protrusions are evenly distributed above the mold; and then pre-embedding in the special concrete cover plate mold Metal screw, and then prefabricate the foamed cement at one time to form a shell fixing plate, fix the shell outline and metal screw on the main structure of the cement base plate, remove the mold after pouring is completed, and maintain and arrange the cement plate.

[0051] In an example, a reusable cementitious substrate was prepared. From the cultivation of laver seed cells to the formation of laver seedlings, the shell growth base has completed the parasitic mission, and the next laver seed cell breeding cycle will not be reused, and new shells need ...

[0069] In embodiments N1-N3, large shells are fixed in plastic molds; in embodiments N4-N6, small shells are fixed in plastic molds. In Examples N1-N6, the cement is PO52.5 Portland cement; the particle size of the fine sand is less than 1mm; the particle size of the ceramsite is 0.5-1.5; the organic foaming agent is Sodium Lauryl Sulfonate Foaming Solution.

[0070] When N=1, the water reducer is a TPEG type carboxylic acid water reducer, and its structural formula is as follows:

[0071]

[0072] Wherein, M is a metal ion combined with a carboxylate; n is 30-60, m is 30-60; x and y are positive integers, and x:y=1:(2-3); the organic polymer polymer The product is hydroxymethyl cellulose organic polymer.

[0073] When N=2, the water reducer is a modified carboxylic acid water reducer. The specific synthesis process can be found in the patent (patent number: 201510308918.7), and its structural formula is as follows:
