Abstract
The invention discloses a kind of ecological culture pond for improving crab cultivation yield, described culturing pool bottom surrounding is provided with multiple tracks zanjon, it is in Back Word type between the zanjon, culturing pool is set to be divided into multiple tracks profundal zone and phytal zone, in the phytal zone, the corresponding water surface is set up plant floating bed, the water-bed laying artificial aquatic weed in phytal zone, submerged plant is planted in profundal zone.Pond waters is divided into by multiple alternatively distributed profundal zones and phytal zone by zanjon, when water body is contaminated, when water transparency reduces, new shelling environment close to the water surface is provided for crab using phytal zone, lift the survival rate of crab, the cultivation density of crab is provided simultaneously, increases the crab yield of unit area.
Description
Technical field
The present invention relates to technical field of aquaculture, and in particular to a kind of ecological culture pond for improving crab cultivation yield.
Background technology
It is very high to propagate requirement of the crab to plant artificially, cultivates the pond of crab at present, it is desirable to which area is typically in 1-5
Mu is advisable, and crab pond condition is had abundant water resources, and water quality is good, and Inlet and outlet water is convenient, and the depth of water is typically preferably 1-1.5 rice.Crab bottom of pond quality
Preferably sandy loam, gravel soil, venting capability is good, is advantageous to pasture and water, bottom is dwelt the growth and breedings of animals and plants, can provide day for river crab
Right feed, bottom of pond silt depth are usually no more than 5 centimetres.
Crab likes the water body environment that water quality is peace and quiet, transparency is larger into crab, and optimum is grown thickly in pasture and water, what bait enriched
Survived in water body, thus more options pond, lake, river are swung and the cultivation base of the Freshwater ecosystems as crab such as rice field.So
And in recent years because extensive seining cultivation year after year, the water body of many cultivation bases are caused water by different degrees of pollution
Body is degenerated, and submerged plant largely reduces, and water transparency reduces so that the growth and breeding of crab is influenceed and limit by certain
System, yield also decline therewith.On the other hand, crab is in growth course, can grow up into crab after multiple shell, and crab
Level can be minimized in the survival ability in shell stage, the death rate is high, and in order to ensure the shell of crab, crab agriculture is needed to water
Body launches a large amount of pasture and water, and this has aggravated the water pollution of Yangcheng Lake, and the cultivation for steamed crab is more unfavorable.
The content of the invention
The invention provides a kind of ecological culture pond for improving crab cultivation yield, from the angle lifting of protection crab shell
The survival rate of crab, while the cultivation density of crab is provided, increase the crab yield of unit area.
The present invention is achieved by the following technical solutions：
A kind of ecological culture pond for improving crab cultivation yield, multiple tracks zanjon, institute are provided with described culturing pool bottom surrounding
It is in Back Word type to state between zanjon, culturing pool is divided into multiple tracks profundal zone and phytal zone, and in the phytal zone, the corresponding water surface, which is set up, plants
Thing floating bed, the water-bed laying artificial aquatic weed in phytal zone, submerged plant is planted in profundal zone.
Wherein, described deep water sector width is in 1-1.5m, and shallow water sector width is in 0.7-1m, profundal zone and phytal zone depth phase
Poor 0.5-0.8m.
Wherein, the depth of water of described phytal zone is in 0.8-1.3m.
Wherein, the area ratio of the profundal zone and phytal zone is 1:0.3-0.6.
Wherein, the described plant floating bed kickboard unit by being connected with each other is formed, and floating bed basketry is installed in kickboard unit, its
Middle plantation emergent aquactic plant.
Wherein, described emergent aquactic plant includes the stem or leaf of cattail, Chinese celery, wild rice stem Xun, cattail or iris.
Wherein, described submerged plant includes eel grass, waterweed, watermifoil or hydrilla verticillata.
The present invention has the beneficial effect that：
Compared with prior art, the present invention plants pasture and water, so as to increase by setting back-shaped deep water ditch at pond bottom in deep water ditch
Add the optimum plot size that crab is cultivated in pond, realize the high-density breeding of crab in pond, divided pond waters by zanjon
For multiple alternatively distributed profundal zones and phytal zone, when aquatic environment is preferable, crab can inhabit phytal zone, can during shelling
To inhabit in the pasture and water of profundal zone, when water body is contaminated, water transparency reduces, and the submerged plant of profundal zone degenerates can not
In the case of providing effective shell environment for crab shell, the new shelling ring close to the water surface is provided for crab using phytal zone
Border, while floating bed plant has interception, and dark environment can be provided for crab shell, coordinates the water-bed artificial water in phytal zone
Grass, strengthen the disguise of shell environment, avoid to water body and launch excessive pasture and water and aggravate the phenomenon of water pollution.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Close specific embodiment and the present invention is expanded on further.
A kind of ecological culture pond for improving crab cultivation yield, described culturing pool bottom surrounding is provided with multiple tracks depth
Ditch, it is in Back Word type between the zanjon, culturing pool is divided into multiple tracks profundal zone and phytal zone, in the corresponding water surface frame in the phytal zone
If plant floating bed, the water-bed laying artificial aquatic weed in phytal zone, plantation submerged plant eel grass, waterweed in profundal zone.
Deep water sector width is set to differ 0.8m, shallow water with phytal zone depth in 0.8m, profundal zone in 1.2m, shallow water sector width
For the depth of water in area in 1m, the area ratio of profundal zone and phytal zone is 1:0.6
The described plant floating bed kickboard unit by being connected with each other is formed, and floating bed basketry is installed in kickboard unit, wherein plantation is endured
Water plant iris.
