Caulerpa stolon induction method

Abstract

The invention belongs to the technical field of seaweed cultivation, and particularly relates to a caulerpa stolon induction method which comprises the following steps: fixing caulerpa to a cultivation plate by using a fixing assembly, enabling the caulerpa to penetrate through adjusting holes, and enabling stolons to be positioned below the cultivation plate; according to induction requirements, adjusting the position of caulerpa through the fixing assembly so as to adjust the cultivation density of the caulerpa; turning on a light supplementing lamp; when the vertical length of the stolons reaches 3 cm or above, starting an injection pump, adjusting water flow, and guaranteeing that the stolons are in a rapid growth state. According to the scheme, the growth advantage of the stolons and the weight ratio of the stolons in algae can be remarkably improved, meanwhile, growth of spheroids is inhibited, the stolons can have better flow resistance and toughness through adjustment of water flow and nutritive salt concentration caused by the injection pump, and by means of the characteristics, necessary conditions are created for field planting and growth of the caulerpa in a marine ranch; and the cultivation density of the caulerpa can be properly adjusted, and favorable conditions are created for reliable cultivation of the caulerpa.

Description

technical field [0001] The invention belongs to the technical field of seaweed cultivation, and in particular relates to a method for inducing stolons of fern algae. Background technique [0002] In the existing cultivation technology of Pteridophyta, the growth of stolons, erect stems and spheroids is greatly affected by factors such as water quality, microgravity, light and water flow. The main purpose of artificial cultivation on land is to obtain more spheroids , so the proportion of stolons produced by conventional culture methods is low, and the stability of algae strains is relatively weak. [0003] Defects: As the main fixed organ of algal strains, stolons play an important role in resisting external forces. Due to the large volume of fern algae, the buoyancy and water flow resistance in the water body are also large, and the ability of algal strains to resist external shocks is very weak , fern algae is a kind of macroalgae that is very suitable as the structure of...

[0002] In the existing cultivation technology of Pteridophyta, the growth of stolons, erect stems and spheroids is greatly affected by factors such as water quality, microgravity, light and water flow. The main purpose of artificial cultivation on land is to obtain more spheroids , so the proportion of stolons produced by conventional culture methods is low, and the stability of algae strains is relatively weak

[0003] Defects: As the main fixed organ of algal strains, stolons play an important role in resisting external forces. Due to the large volume of fern algae, the buoyancy and water flow resistance in the water body are also large, and the ability of algal strains to resist external shocks is very weak , fern algae is a kind of macroalgae that is very suitable as the structure of the algae farm in the South China Sea marine ranch, but the water flow and wind waves in the open sea have a great impact on the effective attachment of the algae. How to ensure the survival rate in marine ranching or open sea areas has become a problem that must be solved first
