Method for constructing manually controlled submarine algae field

Abstract

The invention provides a method for constructing a manually controlled submarine algae field. The method comprises the steps of selection and treatment of seaweed substrates, culture of seedlings of seaweeds, sowing and the like, wherein the seaweed substrates are breeding screens formed by weaving reddish brown ropes; the step of culture of seedlings of seaweeds comprises the substeps of collection of seedlings of seaweeds and management of culture of seedlings; after the water density of the collected spores during release in the substep of collection of seedlings of seaweeds reaches 10-15 zoospores in the field of 100-times microscope, the seaweed substrates are put in the seawater to adhere; and the adhesion density is 20-30 embryo spores in the field of 100-times microscope. The method has the following advantages and beneficial effects: the variety, density, place and sowing time of the submarine algae field achieve manual control; the fixed substances of the algae, such as C, N, P and the like, are taken from the sea to the land by harvesting the seaweed, so the effect on solving the ecological problems is longer; the cost is far lower than that of the artificial reefs; thenatural submarine geomorphology is not damaged; and the submarine algae field can be formed in a shorter time, thus rapidly increasing the resource quantity.

Description

technical field [0001] The invention relates to an artificially controlled seabed algae field construction method. Background technique [0002] The impact of forests on the terrestrial environment has long been valued by people, and the impact of marine algae, as forest trees in the ocean, on the marine ecological environment has also been valued by marine workers. The bioremediation effect of macroalgae on marine ecology is a consensus in the marine ecology community: algae absorb CO in water 2 , participate in the global carbon cycle and consume atmospheric CO 2 effect to achieve the goal of controlling greenhouse gases; the O emitted by algae photosynthesis 2 It increases the dissolved oxygen content in the water body and improves the water quality; the algae absorb inorganic salts such as N and P, which can solve the problem of marine eutrophication and reduce the resulting marine ecological crises such as red tides and the explosive proliferation of Enteromorpha; Th...

AI Technical Summary

Problems solved by technology

[0005] In view of the problems in the prior art that artificial algae reefs are difficult to achieve long-term fixation of C and N, the cost is too high, the time-consuming is long, and the seabed landform will be destroyed, the present invention provides a method for artificially controlling the construction of seabed algae farms. The present invention directly puts large-scale economical seaweed seedlings into the seabed, artificially and actively places seaweed seedlings into the seabed at a fixed point, quantitatively, at a fixed time, and types, and builds a seabed algae field using economical algae to obtain economic benefits; the present invention fixes C and fixes N The effect is good; the cost is low, the investment is small; the natural landform of the seabed is not destroyed; and the seabed algae field can be formed in a short period of time
