Problems solved by technology

[0003] The pond cultivation method of the prior art has low yield per unit, poor color formation of algae, many miscellaneous algae, high probability of algae beads being damaged by predators such as fish, shrimp, and crabs, and low production efficiency;
[0004] In the prior art, although the yield per unit area and the cultivation stability of the intensive cultivation method have been significantly improved, because natural seawater is used, the substrate is sea mud, and the algae attachment base is made of nylon mesh or plastic mesh, resulting in the fineness of the algae. There is no difference from pond cultured products. The algae are attached with a large amount of organi

Embodiment 1

[0019] Step A, implant the rhizoids of the Botrytis elongatum used for cultivation into a block-shaped attachment base made of polyurethane sponge with a thickness of 5 cm, ensuring that the incision end of the rhizome is wrapped in the middle of the polyurethane sponge, The density between beads can reach 2cm*2cm, which ensures a higher unit density;

[0020] Step B, adjusting the light in the sea grape cultivation factory area to 2500lux through the light control system;

[0021] Step C, the water depth of the cultivation pool is 1.8m, and the water temperature during the cultivation period is ensured to be 28°C through the flowing water and ventilation system, so that the algae are in a high-speed growth state;

[0022] In step D, the cultivated seawater is precisely processed and purified, and all nutrients are manually configured to ensure the nutritional needs of algae growth and ensure the quality, safety and stability of the product. The concentration of nutrient salt...

Embodiment 2

[0025] Step A, implant the rhizoids of the Botrytis elongatum used for cultivation into a block-shaped attachment base made of polyurethane sponge with a thickness of 5 cm, ensuring that the incision end of the rhizome is wrapped in the middle of the polyurethane sponge, The inter-bead density is 2cm*2cm, ensuring a higher unit density;

[0026] Step B, adjusting the light in the sea grape cultivation factory area to 3500lux through the light control system;

[0027] Step C, the water depth of the cultivation pool is 2m, and the water temperature during the cultivation period is ensured to be 30°C through the running water and ventilation system, so that the algae are in a state of high-speed growth;

[0028] In step D, the cultivated seawater is precisely processed and purified, and all nutrients are manually configured to ensure the nutritional needs of algae growth and ensure the quality, safety and stability of the product. The concentration of nutrient salt N is 15ppm, t...

Embodiment 3

[0031] Step A, implant the rhizoids of the Botrytis elongatum used for cultivation into a block-shaped attachment base made of polyurethane sponge with a thickness of 5 cm, ensuring that the incision end of the rhizome is wrapped in the middle of the polyurethane sponge, The density between beads can reach 2cm*2cm, which ensures a higher unit density;

[0032] Step B, adjusting the light in the sea grape cultivation factory area to 3000lux through the light control system;

[0033] Step C, the water depth of the cultivation pool is 3m, and the water temperature during the cultivation period is ensured to be 30°C through the running water and ventilation system, so that the algal body is in a state of high-speed growth;

[0034] In step D, the cultivated seawater is precisely processed and purified, and all nutrients are manually configured to ensure the nutritional needs of algae growth and ensure the quality, safety and stability of the product. The concentration of nutrient...

Abstract

The invention provides a long stem grape caulerpa industrial cultivating method. The long stem grape caulerpa industrial cultivating method includes the following steps that step A, rhizoid of long stem grape caulerpa to be cultivated is implanted in a massive adherence made of polymeric sponge, and it is guaranteed that a cut end of the rhizoid is wrapped in the middle of the polymeric sponge; step B, light ray of a sea grape cultivating factory is adjusted to 2500-3500 lux through a light ray regulation control system; step C, the water depth of a cultivating pool is not lower than 1.8 m, the water temperature ranges from 28 DEG C to 30 DEG C, and the growth of caulerpa body is guaranteed; step D, nutritive salt is obtained after accurate processing and purification are performed on sea water for cultivating, and the nutritional requirement of the growth of the caulerpa body is guaranteed. The long stem grape caulerpa industrial cultivating method uses eutrophic sea water to cultivate the sea grape, the discharged waste water is actually sea water cleaner than cultivating water, the cultivating method by adopting the cultivating pool achieves land cultivation of the long stem grape caulerpa, a large number of sea areas are saved, and therefore the cultivating process of the long stem grape caulerpa is convenient to manage.

Description

technical field [0001] The invention belongs to the industrialized production of V. elongatus and other algae, in particular to the industrialized production of marine macroalgae under controllable environmental conditions. Background technique [0002] Botrytis elongatus is a high-value large edible algae. At present, it mainly relies on the collection of natural resources, and a small amount of artificial cultivation. Existing artificial cultivation method the one, pond extensive formula cultivation method, the 2nd, cement pond cultivation method. The intensive artificial cultivation currently implemented in Putian, Fujian and Hainan generally uses nylon mesh or plastic mesh as the substrate for algae, and the cultivation density and yield per unit area of ​​sea grapes have been significantly improved compared with pond cultivation. [0003] The pond cultivation method of the prior art has low unit yield, poor color formation of algae, many miscellaneous algae, high proba...
