Description

A kind of sea-plant breeding arrangement
Technical field
The utility model relates to marine algae cultivation field, especially relates to a kind of sea-plant breeding arrangement.
Background technology
Grow thickly in tangleweed intertidal zone inferior segment and seabed, subtidal zone phytal zone between middle and high latitude marine site, as supporting plant and other planktons, necton and zoobenthos and the envirment factor that coexists with it forms the offshore ecosystem jointly.Be that the sea jungle supported has very high primary productivity with tangleweed, form complicated animals and plants food web can the eutrophication such as enrichment of N, P salt simultaneously, restrains " red tide " outburst, protect the marine environment.The economic worth that sea jungle is created is very large, and marine alga itself has industry, edible, medical value, the place that sea jungle more provides fish forage, keeps away enemy, lays eggs.But show according to nearest observed result, sea jungle disappears, seaweed bio diversity declines simultaneously.
Reparation at present with regard to sea jungle has some researchs, mainly contains and sets up nature reserve, reduce the destruction of human activity; Carry out the biological research of artificial propagation and related work, as room heat source and seed intermediate rearing.During artificial breeding, gather ripe kind algae more in laboratory, carry out Spawning, zygote sprouting, be attached on adhesive substrate, grow seedling, though juvenile sporophyte adheres to good on the adherance such as shell, rock, not easily by it input in the seawater; Vinylon rope is made seedling curtain and is kept hanging on sea, but seedling strain growth is unhealthy and strong, and management is inconvenience comparatively; Directly on the rock of intertidal zone, spray spore fluid, spore is successfully sprouted and the probability of set growth is too little.
Utility model content
The utility model be in order to overcome in prior art in sea jungle, breed marine alga time; cause marine alga survival rate low to the initial stage protection deficiency of marine alga seedling; the deficiency of management inconvenience; provide one and be convenient to marine alga seedling apposition growth; marine alga seedling for early growth period provides better protection, is convenient to concentrate throw in and the convenient sea-plant breeding arrangement managed while improving marine alga survival rate.
To achieve these goals, the utility model is by the following technical solutions:
A kind of sea-plant breeding arrangement of the present utility model, comprise float connected by stay cord successively, two bracing frames and balancing weight, two bracing frames are vertically connected, described bracing frame comprises center-pole, the sliding sleeve be slidably connected with center-pole and some fan-shaped support plates around center-pole circumferential directions, fan-shaped support plate is provided with some algae culture bricks, the bottom of described center-pole is provided with Connection Block, described fan-shaped support plate and Connection Block are rotationally connected on vertical plane, support bar is hinged with respectively between sliding sleeve and each fan-shaped support plate upper surface, connected by extension spring between described sliding sleeve and Connection Block, the corresponding lateral edges of adjacent fan-shaped support plate is close to mutually when sliding sleeve is in sliding stroke top dead centre, described float is provided with vent valve, the top of described float is provided with opening up storage tube, the recovery cable being provided with small floating ball in storage tube and being connected with small floating ball.Float, bracing frame are connected by stay cord with breeding block, can put in seawater easily, by float and balancing weight effect, bracing frame is made to be in suspended state, be convenient to carry out observing and managing, algae culture brick is in seawater region at the middle and upper levels, is convenient to marine alga and obtains sufficient sunlight and nutrient.When sliding sleeve is in sliding stroke top dead centre, fan-shaped support plate is mutually drawn close and is close to, and is convenient to marine alga seedling apposition growth on algae culture brick, improves the survival rate of marine alga seedling, plays better protective effect.When after seaweed growth, weight constantly increases, fan-shaped support plate rotates around Connection Block under gravity, the elastic force making sliding sleeve overcome extension spring moves down, realize the expansion of fan-shaped support plate, gap between fan-shaped support plate increases, be separated from each other, the marine stream inside and outside bracing frame is more convenient, improves the growth rate of marine alga further.Discharged by air in float by vent valve effect, bracing frame can sink, and the small floating ball simultaneously in storage tube floats, so that manager identifies thus salvages in time.
