Description
Technical field
The present invention relates to technical field of aquaculture, more particularly to a kind of leech hatching apparatus.
Background technology
Leech is commonly called as leech, leech, ox leech etc., and the alias of various regions is very much, and most peasants both know about, and leech is always
Be grown in rice terrace, pond, among creek, it is a kind of well sold and in short supply rare traditional Chinese medicine raw material both at home and abroad, has blood-breaking promoting menstruation,
Disperse accumulation dissipates the effect of stasis of blood, subdhing swelling and detoxicating and induced abortion.Research in recent years finds, leech to tumour, hepatitis and angiocardiopathy all
There is significant curative effect.
Known leech has kind more than 600 in the world, and just there are tens kinds, but medicinal mainly expanded letter gold thread in wherein China
Leech, hiruto and doctor leech, the artificial breeding of these three leech at present has obtained initial success, but still suffers from many deficiencies.Mesh
The breeding oviposition of preceding leech be all using it is imitative it is wild have a cubic metre of earth formula, i.e., in hirudiniculture environment, manually built and be higher by with soil
The oviposition platform of the water surface, allows leech voluntarily to pierce mating in the soil of oviposition platform, oviposition.After leech lays eggs 10 ~ 20 days, people
Work excavates platform soil, takes out the ovum cocoon of leech production, then ovum cocoon is concentrated to hatch and is come.
The following many drawbacks of this mode with the presence of local products ovum：Need to spend a large amount of human and material resources chessons and build
Make oviposition platform；In irrigation and drainage not in time or when raining heavily, there is the risk for being submerged and causing leech and ovum cocoon death in oviposition platform；
The leech parent death rate is higher after oviposition, generally at more than half；The soil of oviposition platform is easily hardened, and leech is pierced in soil
Oviposition is very laborious, while oviposition also consumes one's strength very much in itself, therefore leech is often powerless after laying eggs drills out soil again, in addition soil
In often have the harmful organisms such as spider, cause leech and ovum cocoon injures and deaths；After leech lays eggs in soil, artificial side can only be used
Method, carefully excavates soil, takes out ovum cocoon, moreover, excavated by manual work cocoon is time-consuming, laborious, is also easy to cause ovum cocoon to damage；Further, since
The abuse of pesticide, chemical fertilizer etc. in recent years, causes natural environment seriously to be polluted so that leech of the cultivation in pond or puddle
Living environment be seriously damaged, cause its hatching speed to slow down, incubation rate reduce.
Chinese patent discloses method of some leech without soil breeding, such as Application No. " 201310586156.8 ", patent
The patent of invention of entitled " method of artificial soilless leech hatching ", although patent of the present invention overcomes the above has local products ovum to survive
The shortcomings that rate is low, hatching speed is slow, but still have the following disadvantages：The incubator inner structure for hatching Whitmania pigra Whitman spawns is complicated；In leech
Ovum cocoon hatches after seedling, also needs that manually leech seedling is transferred in box for breeding or aquaculture pond and is cultivated, and seedling can be caused to turn
Shifting is not in time, transfer efficiency is low, allows and takes the deficiencies of artificial.
The content of the invention
It is an object of the invention to overcome the defects of above-mentioned technology and deficiency, Whitmania pigra Whitman spawns survival rate and leech parent are improved
This rate of recovery, solves leech seedling transfer inconvenience, the easily technical problem such as escape in the prior art, and proposes a kind of leech and incubate
Makeup is put.
A kind of leech hatching apparatus, including closed chamber, arranged on the indoor stent of closed box, the hatching on stent
Case, it is structurally characterized in that：The closed chamber is equipped with outlet；In the closed box room, centre was equipped with the rack arrangement
Road, the stent are equipped with multiple object-putting layers；The incubator includes babinet and screen frame, and the babinet is placed in the object-putting layer of stent
On, the screen frame is set up in babinet, and screen frame bottom is equipped with several and can leak through leech seedling but cannot leak through Whitmania pigra Whitman spawns
Through hole.
Preferably, shown closed chamber is container.
Preferably, air curtain is equipped with above the outlet of the closed chamber, constant temperature and humidity machine is equipped with closed box room；It is described
Screen frame bottom is equipped with moisture detector.
Preferably, the bottom of the babinet side offers discharge outlet, vertical in being internally provided with for the babinet opposite side
The filter plate in direction, the filter plate are connected by the guide rail being secured transverse on cabinet wall with box body-sliding, the guide rail
It is equipped with the guide rail buckle for being used to fix the filter plate.
Preferably, the bottom of box and the distance of screen frame bottom are 30-34mm.
Preferably, spraying device is further included, the spraying device includes the aqueduct for being fixed on object-putting layer bottom, described to lead
Fog-spray nozzle is evenly equipped with water pipe, one end of aqueduct connects with external water source and send water to the aqueduct by water pump.
Preferably, one layer of anti-escape net is equipped with the top of the babinet.
A kind of leech mating system, comprises the following steps：
（1）The oviposition bottom portion of constant temperature and humidity is laid on using the foam beads after carrying out disinfection as oviposition substrate；
（2）By leech parent be put into oviposition case in cultivate, by the constant temperature and humidity machine make oviposition the temperature inside the box from
20 degrees Celsius are risen, daily 1 degree Celsius of rise, it is stepped up to 25 degrees Celsius, and detected by the moisture detector
Humidity in oviposition case, makes its humid control 80%（Air humidity）；
（3）When parent is put into oviposition case 15 days, after it is taken out together with ovum cocoon, ovum cocoon is put into the screen frame into
Row hatching, while add water into babinet, it is 20mm to make the depth of water in babinet；
（4）In ovum cocoon 1 ~ 2 day in screen frame will incubation of membrane, and the case is entered by the through hole of screen frame bottom
Tumor growth, when the leech seedling in babinet reaches 1 ~ 20,000, or after leech seedling grows 1 ~ 2 day in babinet, by it
Move into culture pond and cultivated.
Preferably, on the oviposition case anti-release apparatus is used as along by the use of the nylon wire of 20 mesh.
Preferably, water temperature is maintained at 24 degrees Celsius in the culture pond, and the soil moisture is 21 degrees Celsius in culture pond.
The beneficial effects of the invention are as follows：The leech hatching apparatus of the present invention is simple in structure, after hatching Whitmania pigra Whitman spawns emergence, by
There is hydrotaxis in young leech, can voluntarily be entered in the water of the bottom of box and grown by the through hole of screen frame, remove what is manually shifted from
Trouble, and it is avoided that loss caused by transfer not in time；Using no earthwork formula carry out spawning and hatching, reduce a large amount of manpower and materials into
Row chesson, builds oviposition platform；When effectively avoiding raining heavily, ovum cocoon immersion, ovum are dead caused by management is not in place
Phenomenon occur；Reduce a large amount of manpower and materials and carry out digging cocoon, substantially increase the recycling of parent and the survival rate of ovum cocoon after oviposition；
Oviposition and ovum cocoon hatching are carried out in closed box room, easy to temperature control, carries out seed breeding in advance, by properly increasing hatching
Temperature, shortens brooding time, reaches seedling and concentrates membrane purpose, while makes the membrane time earlier than fish wild seed first quarter moon even one
The moon, improves the breeding efficiency of leech.
