Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
embodiment mono-
The bottom culture device of a kind of tangleweed that Fig. 1 provides for the present embodiment, comprises seabed raft frame and spatfall device.Every raft frame consists of two parallel floating well ropes 1, and on every floating well rope 1, with the fixing float 4 of some of rope, described floating well rope 1 connects anchor hawser 6, and anchor hawser 6 is fixed on seabed by anchor 5.By the number of increase and decrease float 4, can change the buoyancy of raft frame in water, coordinate the length of adjusting anchor hawser 6 simultaneously, can the adjusting raft frame end off sea and the distance on sea level, thereby can be according to the different cultivars of tangleweed of cultivation and the different vegetative stages of same kind the demand to light, adjust the residing water layer of raft frame.
In the present embodiment, two ends and centre position at described floating well rope 1 are connected with anchor hawser 6, by anchor 5, be fixed on seabed, adopt 3 fixing modes, can make the fixing more firm of raft frame, setting based on float 4 simultaneously, raft frame is subject to buoyancy upwards, thereby can guarantee the abundant stretching, extension of raft frame in seawater.In the present embodiment, anchor 5 can be made of timber or cement stone roller, to produce enough large gravity, reduces manufacturing cost simultaneously.
Spatfall device in the present embodiment consists of spatfall base 2 and fixed part 3.Fixed part 3 parallel interval are laid between two floating well ropes 1, and every fixed part 3 comprises two parallel static lines.On every fixed part, interval is in series with a plurality of spatfall bases 2.
As shown in Figure 2, floor map for the spatfall base that proposes in the present embodiment, in the present embodiment, spatfall base is circular configuration, at the two ends up and down of spatfall base, be symmetrically arranged with respectively two retainer rings 3, two retainer rings 3 of every end are horizontal, two static lines of described fixed part are respectively from the left and right sides from top to bottom through described retainer ring 3, to guarantee that the spatfall base on same fixed part can and not be wound around mutually by current upset.
On spatfall base, be provided with the parallel preformed hole 2 of many rows, the number of every row's preformed hole 2 is two; In addition, the center of described spatfall base is also provided with a preformed hole 2.Other parts on spatfall base outside retainer ring 3 and preformed hole 2 form the plate 1 of collecting seedling, and the plate 1 of collecting seedling is for directly adhering to tangleweed seedling.By the setting of preformed hole 2, can reduce the pressure of current to spatfall base, thereby reduce destruction and the impact of current on spatfall base and whole raft frame, can make the marine alga seedling on spatfall base fully contact seawater simultaneously, be more conducive to its growth.
In addition, spatfall base is made by shaggy frivolous polyethylene material, is conducive to directly adhering to of tangleweed seedling, and the reusable and frivolous characteristic of polyethylene material, has guaranteed the low cost cultivating and the ease for operation of forming rear harvesting work simultaneously.
The bottom culture of sargassum kjellmanianum Yendo of take is below example, and the operating process of using the bottom culture device that the present embodiment provides is described.
First according to the transparency situation of culture zone seawater, the demand in conjunction with sargassum kjellmanianum Yendo growth to illumination, determines the water layer that raft frame need be placed.Diver is fixed on seabed anchor and anchor hawser, according to the default anchor hawser length of required water layer, afterwards floating well rope being undertaken at 3 by anchor hawser fixes, and on floating well rope the fixing float of some, make whole raft frame full extension, the number that should control float, makes the buoyancy making progress of its generation unlikely excessive simultaneously.Collect seedling plate in workshop or cofferdam through fertilized egg adhere to, two processes of intermediate rearing, when the appended sargassum kjellmanianum Yendo growth of seedling of the plate of collecting seedling is to length approximately (3-5) cm, density (1-2) strain vertical branch/cm
2time, the spatfall of a plurality of plates of collecting seedling is faced up, interval (30-40) cm, with fixed part, conspire to create a string, by diver, the spatfall base of bunchiness is fixed on the floating well rope in seabed one by one again, in the time of fixing, between every two string spatfall bases, keep certain interval, about 70cm left and right, with winding and the shading between avoiding mutually.When sargassum kjellmanianum Yendo grows to certain length, by diver, hauling out sea with the bunchiness spatfall base of sargassum kjellmanianum Yendo, on fishing boat, in the mode of cutting, gathered in the crops, and retain root and be again fixed on seabed raft frame.This kind of breeding way do not need too much sea management, and can Multiple harvests, can when saving human and material resources, realize largeizationr of economic benefit.
embodiment bis-
As shown in Figure 3, the difference of the present embodiment and embodiment mono-is, on spatfall base, also there is seedling rope 4, the two ends of every offspring rope 4 are through two preformed holes 2 in same row, and fixing in the another side knotting of spatfall base, the size of knot 5 is as the criterion to be greater than preformed hole, and this can guarantee that whole offspring rope can be tightened to be fixed on and collect seedling on plate.By the setting of seedling rope, can on spatfall base, cultivate the tangleweed that the plate that is unsuitable for collecting seedling adheres to.In the present embodiment, seedling rope adopts vinylon and polyethylene mixed materials, and vinylon material is easy to spatfall, and polyethylene material can increase seedling rope intensity, and this mixed materials has guaranteed the low cost of cultivation and formed the ease for operation of rear harvesting work.
The bottom culture of agar of take is below example, and the operating process of using the bottom culture device that the present embodiment provides is described.
First according to the transparency situation of culture zone seawater, the demand in conjunction with agar growth to illumination, determines the water layer that raft frame need be placed.Diver is fixed on seabed anchor and anchor hawser, according to the default anchor hawser length of required water layer, afterwards floating well rope being undertaken at 3 by anchor hawser fixes, and on floating well rope the fixing float of some, make whole raft frame full extension, the number that should control float, makes the buoyancy making progress of its generation unlikely excessive simultaneously.The plate of collecting seedling is not used in collecting seedling of agar, and uses seedling rope.After seedling rope is collected seedling, be behind about 2cm through intermediate rearing to growth of seedling to length, seedling rope adhered to one of agar seedling and face up to be fixed on and collect seedling on plate, the two ends of seedling rope are through preformed hole, and in the another side knotting of spatfall base.The spatfall of a plurality of plates of collecting seedling is faced up, keep at a certain distance away that it is a string with fixed part, to conspire to create, then by diver, the spatfall base of bunchiness is fixed on the floating well rope in seabed one by one.After agar is formed, can adopt directly the Miao Shengcong mode of dissociating on plate of collecting seedling is gathered in the crops.
The present embodiment is by the setting of seedling rope, can on spatfall base, cultivate the tangleweed that the plate that is unsuitable for collecting seedling adheres to, thereby make the utlity model has higher applicability.
To one skilled in the art, can make other various corresponding changes and deformation according to technical scheme described above and design, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
