Description
Technical field
The present invention relates to a kind of sargassum kjellmanianum Yendo propagation reef and using method, belong to marine alga multiplication technique field.
Background technology
Sargassum kjellmanianum Yendo (Sargassummuticum) is under the jurisdiction of Sargassaceae, Sargassum, belongs to perennial large-scale brown alga, and the Huanghai Sea and the Bohai Sea that are extensively distributed in the China north are littoral. Frond length is generally at more than 1m, and big frond can reach about 2m. Frond has a large amount of air bags at blade and branch end, can grow from seabed to offshore floating, often forming bigger algae field on the seabed cay of the less gulf of stormy waves and neritic region, it mainly acts on can cultivate feed, the raw material extracting algin and ocean fix tool algae kind as young ginseng.
Sargassum kjellmanianum Yendo propagation algal reef at present more adopts concrete member, be conducive to being fixed on subtidal zone, but the alkaline matter also using concrete member when collecting seedling easily affects the growth of frond seedling, often needs long time treatment, and too heavy, the inconvenience when carrying. In addition, algal reef is generally be permanently secured to propagation place, causes maintenance management inconvenient, and especially sargassum kjellmanianum Yendo growth ecological niche is at subtidal zone, will regularly remove the impact of assorted algae and animal, maintenance management of diving under water only for a long time.
Summary of the invention
Technical problem to be solved by this invention provides a kind of sargassum kjellmanianum Yendo propagation reef and using method, this propagation reef is except the base portion of reef body, spatfall part is light material, and can dismantle, be conducive to frond to safeguard, avoid the destruction to frond in conventional algal reef throwing reef process in use, and after matrix input, algal reef rest part is reusable, it is to increase utilising efficiency and providing cost savings.
The present invention is achieved through the following technical solutions:
A kind of sargassum kjellmanianum Yendo propagation reef, comprises a propagation reef matrix in hollow dome type, and hollow structure is conducive to matrix to adapt to the uneven environment in seabed, and matrix is dome type, surface is smooth, and such structure is unfavorable for the attachment of assorted algae; The bottom of described propagation reef matrix slightly angle be interspersed with three supports, three supports form equilateral triangle structures, are conducive to being stuck in seabed; Being interspersed with 10-15 root anchor in the middle part of the edge of described propagation reef matrix, the top horizontal of propagation reef matrix is covered with the vinylon net curtain of 70 strands, and the edge of vinylon net curtain hangs to be lived with band or tether system on anchor, after open and flat tension.
Above-mentioned sargassum kjellmanianum Yendo propagation reef also has the seedling collector for adhering to sargassum kjellmanianum Yendo seedling, and seedling collector band or tether tie up on vinylon net curtain; Described seedling collector is polyethylene disk, disk diameter 25-30cm, thickness 0.4-0.6mm; The convex surface hairbrush brush of disk spatfall is coarse, around with the aperture of 6-8, tapping and plugging machine brill, diameter 0.5-0.8mm.
The material of above-mentioned propagation reef matrix is concrete and the carbonate cement of engineering, and its weight ratio is 10:1; In order to avoid reinforcing bar in construction process to be corroded, the normal concrete of engineering is that strong basicity, pH are more than 12 usually, the object adding carbonate cement in concrete makes the pH of propagation reef in neutral, preventing matrix long period of soaking from diffusing alkaline matter in marine site, sargassum kjellmanianum Yendo seedling and mariculture area water surrounding can be caused harm by alkaline matter.
The specification of above-mentioned propagation reef matrix is: diameter 1.8-2m, edge thickness 20-25cm, whole height 40-50cm, weight 250-300kg, and the matrix function of this kind of specification meets the requirement of wind and wave resistance, can save again man power and material.
Above-mentioned support and the material of anchor are waste and old reinforcing bar, both can be cost-saving, are rationally recycled by waste again; Whole propagation reef can be fixed on seabed by support, and its length is 30-40cm; The effect of anchor is fixing vinylon net curtain, and length is 8-10cm.
Above-mentioned vinylon net curtain, the specification in net curtain hole is 15-20cm �� 15-20cm, and mesh crosses the little assorted algae that easily overgrows, and excessive is unfavorable for that the disk having seedling is fixed.
The angle that above-mentioned support interts is 15 ��.
The present invention also provides a kind of method using above-mentioned sargassum kjellmanianum Yendo propagation reef to carry out artificial breeding, comprises the steps:
(1) propagation reef matrix and laying bracket, anchor is made: the method making hollow dome according to building, engineering field, multiple planks of width 20-25cm are vertically surrounded and connects by level connection joint component between circle, plank, prepare the mould of a diameter 1.8m, high 20cm; Then in mould, fill reef body material form propagation reef matrix, concrete and the carbonate cement of reef body material to be weight ratio be 10:1; Inserting 10-15 root anchor in the middle part of propagation reef matrix border, anchor head exposes 8-10cm; Equidistant insertion 3 supports bottom propagation reef matrix, the angle of support insertion is 15 ��; After making, place 1 month, often sprinkle water so that it is solidify solid;
(2) sargassum kjellmanianum Yendo spatfall: by coarse for the convex surface hairbrush brush of seedling collector spatfall, around with the aperture of 6-8, tapping and plugging machine brill, diameter 0.5-0.8mm; In indoor, seedling collector is carried out soaking disinfection process, put it into after soaking disinfection and sargassum kjellmanianum Yendo nursery pond is adopted attached juvenile sporophyte; In spatfall process, indoor employing half flowing water mode is cultivated, cultivate 18-22 days, seed carry out marine propagation when growing to 0.5-0.8cm;
(3) pre-treatment is thrown in: cover the seedling collector with seedling with wet cloth wet from sea water, on morning or the bank that at dusk seedling collector and each parts of propagation reef are transported propagation marine site; The edge of vinylon net curtain is hung and lives with band or tether system on anchor, after open and flat tension; Seedling collector band or tether are tied up on vinylon net curtain;
(4) breed reef to throw in and final-period management: with ship, propagation reef is transported to input place and throws in, regularly checking frond growing state by frogman, first 15 days, within every 5 days, diving is observed once, the disk not good by growing state or net curtain take off, and more renew in time; After treating nursery season, net curtain taken off in every 1 month and it is put into bank and removes assorted algae and food algae animal.
Marine propagation described in step 2, propagation marine site is the nearly bank subtidal zone of inner bay, and the stormy waves breeding place is less, substrate is comparatively smooth.
Traditional algal reef is all cement components substantially, the main shortcoming that there are three aspects, and one is drop into seabed after frond adheres to, and no matter adhesion effect quality just can not change again; Two are, spatfall attachment base used is also cement components, and in fact cement components is bigger for the infringement of frond especially seedling; Three is throwing owing to algal reef all to be transported to bank in advance in reef process, and dry dew and sunlight irradiate and frond is had infringement, and collide with unavoidably.
Sargassum kjellmanianum Yendo propagation reef and the tradition of the present invention are bred compared with reef, mainly contain the advantage of four aspects, and one is that frond attachment material changes polyethylene disk into, to algae seedling and breeding environment without any infringement; Two is to dismantle, and attachment material is all light material, safeguards very convenient; Three is to reuse, and after algal reef matrix is thrown in, rest part can be dismantled at any time, reuses; Four is can first throw in matrix when throwing reef, is then fixed on matrix by spatfall material again, and the time is flexible.
