Background technology
Mariculture is the important component part of China's Coastal Areas economy.But the eutrophication that pond seawater animal-breeding causes causes disease and red tide to take place frequently, contaminated environment not only, and jeopardize aquaculture, the economic loss heaviness.Particularly water hypoxia and NH
3Deng harm be the main problem that cultivating pool faces.Utilize fragrant plant mentioned in ancient texts to absorb nutritive salt such as N, P in the water body, emit O simultaneously
2, supply with cultivated animals, can suppress the anaerobic bacteria activity, reduce CH
4, H
2S, NH
3Wait the generation of some toxic and harmfuls, create good breeding environment, strengthen the cultivated animals premunition, improve growth rate.By artificial results marine alga the nutriment in the water body is migrated out system, reach the purpose of alleviating and eliminating eutrophication.This biological restoration approach has become the preferred version of the solution environmental problem of praising highly in the world.But at home and abroad there is no method and technology at the system of subtropics cultivating pool mariculture eutrophication biological restoration.Fragrant plant mentioned in ancient texts is in the past cultured the form that adopts the end to broadcast, but for the depth of water, the pond that water transparency is low, as piscina, because a little less than the light of bottom, the fragrant plant mentioned in ancient texts poor growth, even can't survive.
The utility model content
The utility model aims to provide a kind of bank base fragrant plant mentioned in ancient texts that is mainly used in subtropics cultivating pool eutrophication biological restoration and hangs foster bamboo raft.
The utility model is provided with at least 3 poles that are arranged side by side, the end of pole is connected into support body by rope or support, be provided with the tether that is used to place the biological restoration plant between the pole, support body is provided with at least 1 suspended substance, the heavy part of support body tenesmus that links to each other with suspended substance, be used to keep support body to suspend in water,, support body is fixed on the fixture by at least 1 stationary rope.
The pole that is arranged side by side is parallel to each other, and can select nonmetallic materials such as bamboo, wood or plastics for use, or the light metal material, is preferably tube, and its length is chosen as 2～10m, best 3.5～5m.
Said support body preferably is rectangle, and support body length is preferably 50～70m greater than 10m; Width is preferably 4～5m greater than 2m.Suspended substance can be selected the plastic foam body for use, and heavy part can be selected basic brick, stone etc. for use, but connects the rope and the stationary rope coupling of pole end, and fixture can be selected dead lever for use, stake etc.
Utilize the utility model mainly can implement biological restoration to the cultivating pool of subtropics eutrophication, culture radial striations fragrant plant mentioned in ancient texts or the numerous principal deformation kind of Gracilaria tenuistipitata in raft frame mode, by the results fragrant plant mentioned in ancient texts nutritive salt is constantly migrated out system, the pond eutrophication is alleviated, improved the integrated culture economic benefit simultaneously.
When implementing biological restoration, at first select to be used for the plant of pond, subtropics eutrophication biological restoration, can be selected from fragrant plant mentioned in ancient texts, for example at least a kind in radial striations fragrant plant mentioned in ancient texts (Gracilaria lichenoides) or the numerous principal deformation kind of Gracilaria tenuistipitata (Gracilaria tenuistipitata.var.liui) etc.The plant that will be used for pond, subtropics eutrophication biological restoration hangs the raft frame of supporting at pond water, and its initial hanging is supported density less than 300kg/ mu, is preferably 100～200kg/ mu; Gathered 1 time every 15～35 days, restrict between preferably and gather, promptly every two adjacent seedling ropes are gathered 1, and the seedling rope after gathering covers seedling, and cultivation density is preferably 200～600kg/ mu less than 600kg/ mu.
The utility model can adopt the reparation biology of the different growth comfort zones that are suitable for winter and summer, realizes annual uninterrupted the reparation.Can pass through the degree of depth under water of any adjusting raft frame of rope length of connection raft frame upper rack posts and plastic foam body, be suitable for the pond culture water body of different transparencies.Rope is gathered in the crops between the utility model employing, a rope is filled the gaps with seedlings method, can keep that an amount of reparation biology is arranged in the water body at any time.It is practical, and is easy and simple to handle, be easy to promote.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the plant that is used for pond, subtropics eutrophication biological restoration is selected from the radial striations fragrant plant mentioned in ancient texts.Hanging raft culture frame is provided with 12 bamboo poles that are parallel to each other 1, the end of bamboo pole 1 is connected into support body by rope 2, be provided with the seedling rope 3 that is used to hang health thing rehabilitation plant between the bamboo pole 1, support body is provided with plastic foam ball 4, be used to keep support body to suspend in water, the bottom of the plastic foam ball 4 basic brick 7 that drops, support body is fixed in the bamboo stake 6 by 4 stationary ropes 5.The length of bamboo pole is chosen as 4.2m.Support body is rectangle, and support body length is 60m; Width is 4.2m.
The plant radial striations fragrant plant mentioned in ancient texts that will be used for pond, subtropics eutrophication biological restoration hangs the raft frame of supporting at pond water, and it is initial to hang that to support density be 200kg/ mu.
When water temperature is higher than 22 ℃, can select for use the radial striations fragrant plant mentioned in ancient texts biological as repairing, when water temperature is lower than 30 ℃, biological as repairing with the numerous principal deformation kind of Gracilaria tenuistipitata.The two covers annual lasting reparation in conjunction with forming.
The length of fragrant plant mentioned in ancient texts hanging raft culture frame and the length in pond are approaching, general 50～70m.Each connects 1 plastic foam ball 4 with rope bamboo pole 1 two ends, and the basic brick 7 that drops is fixed on 0.3～0.5m depths under water with the row's of putting in order bamboo raft, and rope 2 two ends are fixed in the bamboo stake 6 on bank.Distance 0.5～1m between adjacent raft frame.
When the reparation biology was put in a suitable place to breed, the fragrant plant mentioned in ancient texts seedling pressed from both sides seedling with rope, and the seedling rope adopts the plastic ties of diameter 5～6mm, every interval 15～20cm folder cluster fragrant plant mentioned in ancient texts, every bunch of fragrant plant mentioned in ancient texts weighs 10～15g, and the seedling rope is hung on the bamboo raft, hang a seedling rope every 30～40cm, keep the seedling rope to be positioned at 30～50cm place under water.
Hang rope results between foster fragrant plant mentioned in ancient texts employing, the mode that a rope is filled the gaps with seedlings is regulated fragrant plant mentioned in ancient texts density.Initial the hanging of fragrant plant mentioned in ancient texts supported the about 150kg/ mu of density, first fragrant plant mentioned in ancient texts of gathering behind the 30d, and rope is gathered between employing, and every two adjacent seedling ropes are gathered 1, keep 1, and the seedling rope after gathering is by the density covering fragrant plant mentioned in ancient texts seedling of 75kg/ mu.After this gather 1 time every 25d, the fragrant plant mentioned in ancient texts of gathering is the fragrant plant mentioned in ancient texts of not receiving last time, and the density with 75kg/ mu covers the fragrant plant mentioned in ancient texts seedling equally again.If the day growth rate of fragrant plant mentioned in ancient texts is in 3%, the about 100kg of the fragrant plant mentioned in ancient texts amount of gathering for the first time then, the about 300kg of the amount of the gathering second time, the about 250kg of the amount of gathering at every turn later on.The cultivation density of fragrant plant mentioned in ancient texts is 230～490kg/ mu under the normal condition.
