Description
Technical field
The present invention relates to sea grass bed restoration of the ecosystem field, specifically a kind of semi-submersible type sea grass breeding apparatus and breeding method.
Background technology
The sea grass in flakes of large area is referred to as sea grass bed, and sea grass bed is that the rare marine organisms such as dugong, green turtle, hippocampus take
It eats ground, habitat, nursery or protects place, be called " aquafarm ", be the high marine characteristics ecology of littoral productivity
System plays important ecological functions, with coral in fixed substrate, protection seashore, improvement water quality and the biological young of breeding etc.
Coral reef and mangrove are known as the littoral three big ecosystems.But it is disliked recently as the continuous expansion of mankind's activity range and environment
Change, sea grass bed decline situation getting worse, therefore, carries out the recovery of sea grass bed for protecting existing sea grass resource, protect ocean
Ecological environment has a very important significance.
Traditional sea grass bed restoration methods mainly have Habitat pattern method, the seed law and grafting.Habitat pattern method is to pass through
Protection, improvement or simulation habitat, to achieve the purpose that gradually to restore, are a time cycles by the natural procreation of sea grass
Veryer long process；And the seaweed seeds of the seed law are not easy to acquire, and are after planting easy to lose, germination rate is low；Grafting is divided into grass
The advantages of pico farad, grass block method and root-like stock method, root-like stock method grafting be adopt grass careless source is destroyed it is smaller, be at present more often
Method.Although the application of grafting plays good effect to the reparation of damaged sea grass bed, there is also some disadvantages, lead to
The mode for crossing transplanting is repaired, and the introduces a collection for finding sea grass, the plant of transplanting is needed to be difficult to have effect very little, is transplanted too much to introduces a collection
Ground sea grass resource can cause larger destruction again, a large amount of from provenance under the overall background of existing sea grass bed slump of disastrous proportions
Transplanting sea grass is simultaneously infeasible, and it is a kind of feasible method that the sea grass of provenance is bred proliferation on suitable beach, but
It is very difficult that the beach that one piece can breed as sea grass is found under the serious environment of natural water front scarcity littoral zone artificial destruction,
And by the plant of indoor culture, the ability for adapting to field is again poor, and therefore, research is a kind of to utilize less sea grass introduces a collection, passes through
The mode that field is cultivated obtains the relatively large method that can be used for repairing sea grass bed sea grass resource, aobvious to marine ecology repair
It obtains particularly important.
Invention content
The technical problem to be solved by the present invention is to：Less sea grass introduces a collection can be utilized by providing one kind, be cultivated by field
Mode obtain it is relatively large can be used for repair sea grass bed sea grass resource sea grass breeding apparatus and breeding method.
The technical solution adopted in the present invention is：There is provided a kind of semi-submersible type sea grass breeding apparatus, including braced frame, floating
System, sinker and anchor system, the floating system include float and connecting rope, and anchor system includes anchor and connecting rope, floats and is attached to support frame
Frame upper end, sinker and anchor are attached to braced frame lower end；The cultivation for cultivating sea grass is provided in the braced frame
Layer is cultivated and is equipped with the coating with sieve pore above layer.
The braced frame includes bottom plate and frame, and the bottom plate is band sieve pore degradation resistant material, and sieve diameter is small
In 0.5cm, the frame is set to bottom plate surrounding, and supporting layer is set on bottom plate.
The cultivation layer is the soft free of contamination biomaterial of concrete dynamic modulus seawater corrosion resistance.
The coating is the nylon rope net of 3 ~ 5cm of sieve diameter.
The present invention also provides a kind of breeding methods for cultivating sea grass using above-mentioned apparatus, include the following steps：
1）Whole device is placed on the outside of beach to be repaired at deep water, by anchor, system is fixed；
2）The sinker for removing braced frame makes braced frame float on the surface in the case where floating system acts on；
3）The root system for transplanting sea grass is filled in from the sieve pore of netting, is inserted into and cultivates in layer, the walk of 3 ~ 5cm of sea grass tether panel,
Walk external application degredation plastic film wraps up, and the spacing between sea grass in supporting layer is 20 ~ 25cm；
4）Sinker is connected in braced frame, braced frame is made to sink to 30 ~ 0.5 times of transparencies under sea；
5）After the completion of sea grass is cultivated, sinker is removed, braced frame climbs up on top of the water, and removes nylon rope net, and removal is cultivated layer, will be cultivated
Sea grass transplanting to beach to be repaired on.
The beneficial effects are mainly as follows the following aspects：
（1）Device is placed on deeper sea area near area to be repaired, and environmental quality is close with area to be repaired, the sea grass of cultivation
It is more easily adapted to conform to than the breeding of indoor or strange land.
（2）Semi under water within the scope of 30cm ~ 50cm, can prevent sea grass seedling by alluvion death, and can
Ensure sufficient illumination.
（3）The nylon rope net in the apertures 3 ~ 5cm, you can to ensure that sea grass is smoothly planted, and can be when harvest opens net not
Damage sea grass.
（4）The Tideland resources of suitable sea grass growth need not be found, it is applied widely.
（5）It is high in the slightly remote marine site seawater transparency of offshore, be conducive to sea grass photosynthesis.
（6）Sea grass can pass through root system and absorb N, P in seawater in the higher summer and autumn growth of water temperature when breeding growth
Deng, the nutrient concentration in reduction coastal seawater, purifying sea water water quality.
