Long stem grape caulerpa industrial cultivating method

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...

AI Technical Summary

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 organic floating mud, and the excessive heavy metal ions accumulated in the floating mud are enriched and concentrated by the algae, so that this high-end product, which is mainly eaten fresh, cannot meet the quality standards. On the other hand, nylon mesh and plastic mesh are used as the attachment base, which causes the growth rate and weight of rhizoids to far exceed the weight of vertical stems and sea grapes. As a result, rhizoids have obvious growth advantages, and the vertical stems of sea grapes become relatively short. An important criterion for measuring the quality of sea grapes is the vertical height of algae beads, so this method cannot obtain ideal commercial results.
