Description
Technical field
The invention belongs to ecological restoration technical fields, and in particular to a kind of discarded shrimp pool restoration of the ecosystem for simulating natural deduction
Method.
Background technique
The shrimp pool is discarded to have become the common problem that global shrimp farming faces.It is driven by economic interests, prawn culturing working
Person pursues high-density breeding, and disease is caused to take place frequently, and cultivates success rate sharp fall；Residual bait and excrement accumulation deteriorate water quality, into
One step aggravates disease, and the shrimp pool is often just discarded after using several years, therefore in improvement, and common method formula is red by planting
The woods transform a part on the shrimp pool as mangrove and administer.
In existing discarded shrimp pool restorative procedure, the method for being able to use restoration of the ecosystem is repaired only by plantation mangrove
Multiple, repairing effect is slowly unobvious, while in otherwise repairing and treating, often carries out auxiliary using chemical substance and repairs
It is multiple, secondary hazards not only are caused to environment, while increasing the cost for the treatment of, can not accomplish the effect that ecological circulation is administered, because
A kind of discarded shrimp pool ecological restoring method for simulating natural deduction is provided in this present invention.
Summary of the invention
It is above-mentioned to solve the purpose of the present invention is to provide a kind of discarded shrimp pool ecological restoring method for simulating natural deduction
The problem of being proposed in background technique.
To achieve the above object, the invention provides the following technical scheme: a kind of discarded shrimp pool ecology for simulating natural deduction
Restorative procedure, comprising the following steps:
Step 1: coastal area receive naturally tide seawater aquaculturing pond mouth at be arranged arc protective net, the radius of protective net is about
It is 2~5 times of sluice gate width, mesh aperture will be convenient for the discharge of fish-egg, while prevent juvenile fish from escaping, about 20~50 mesh；
Step 2: according to the water level feature of local mean low-water, prawn pool pool bottom is transformed, and constructs beach and waters,
And a certain number of tidal creeks are excavated in Coastal Area.
Step 3: loose heavy by launching the deposition feeding habits zoobenthos such as clam worm, fiddler crab, Phascolosoma, razor clam of hanging
Product object, improves benthic environment quality geological state.
Step 4: will be close to the non-Coastal Area near sluice gate and dig deeply, and water fender is arranged near sluice gate, the height of water fender
Degree retains the depth of water of 0.5m~1m when should ensure that ebb tide.
Step 5: the deposition feeding habits benthon such as clam worm, Phascolosoma, capitellid, razor clam of hanging is launched, the shrimp pool is transformed
Sediment quality repairs the Sediment environment of seawater aquaculturing pond, has reached the purpose that nature repairs substrate situation.
Step 6: in the ecological region planting native country strand plant that the shrimp pool is padded, according to beach elevation and plant ecological position feature,
Construct purebred woods or mixed forest.
Step 7: launching the economic animals seeds such as crab, mudskipper in beach, rationally control cultivation density and cultivation type,
To reach three-dimensional culture and ecologic breeding effect.
Step 8: the economic animals seeds such as fish, shrimp are launched in waters, control cultivation density and cultivation type, rationally to reach
To three-dimensional culture and ecologic breeding effect.
Preferably, in the step 1, selection is along the sea shrimp pool, or selection can be by tidal creek according to natural tide prawn
The pool carries out diversion and draining.
Preferably, in the step 4, prawn pool bottom configuration is transformed, and a part is suitable for planting mangrove, and one
Part is suitable for sea-farming, can distinguish the different function of flood tide or ebb tide period.
Preferably, in the step 5, prawn pool substrate situation is transformed, including but not limited to perinereis aibihitensis Grube, mud
The zoobenthos such as worm, razor clam of hanging further include the similar animal with corresponding function.
Preferably, in the step 6, the region of mangrove is planted after the topography reform of the shrimp pool, can be not limited to purebred woods
Or mixed forest, drawing also can be used and close the rapid mangrove kinds of growths such as wood, but should ensure that species are controllable.
Preferably, the mangrove includes Avicennia marina, paulownia, Rhizophora stylosa, and Plant plane is 1m × 1m, and shrimp pool mangrove is covered
Lid rate is 40~60%.
Preferably, in the step 7, appropriateness launches the economic animals seed such as Scylla paramamosain and mudskipper, can also fit
Degree launches the species such as Penaeus Vannmei, economic fish, the cultivation density rationally customized
Preferably, described, further include that will select vacant lot by the selected shrimp pool, remove weeds, plough deeply soil, level land bedding, furrow are wide by 4
~5m opens up groove, 30~35cm of ditch groove width, 30~35cm of ditch depth, for planting sea water vegetable, the kind packet of vegetables between furrow
Include red witloof, luxuriant apricot, wild cabbage, extra large asparagus, haiying cuisine.
Compared with prior art, the beneficial effects of the present invention are: the present invention using bottoms such as perinereis aibihitensis Grube, mud worms by being dwelt
Animal changes shrimp pool geological state, reduces the use of the chemical substances such as pesticide, chemical fertilizer, avoids secondary environmental pollution, simultaneously
The cost of improvement is greatly reduced, while water is changed to increase the zoobenthos such as perinereis aibihitensis Grube, mud worm according to tide spontaneous fluctuation
Food source reduces bait and launches, reduces the cost of cultivation, while introducing simulation natural deduction process, the growth of mangrove,
For the various economic living seeds launched entirely by growing naturally, high density large capacity is not pursued in the sufficiently simulation naturally survival of the fittest,
So that the growth of economic living is healthier, more naturally, design through the invention not only repairs the discarded shrimp pool ecosystem, together
When increase mangrove area, increase carbon storehouse capacity so that administer ecology.
