Abstract
The invention discloses a kind of leech hatching method, it is related to technical field of aquaculture, comprises the following steps：A, the ovum cocoon that contemporaneity is formed is positioned in same incubator；B, incubator bottom spreads the hatch soil that a layer thickness is 1.0~1.5cm, and ovum cocoon is mixed with the carboxyl chitosan of its weight 2~3% in one layer of hatch soil of lid thereon, hatch soil after being well placed, the humidity of hatch soil is 32~42%；C, incubator is put into hatching house, and the relative air humidity for controlling hatching house is 65~75%；The temperature of hatching house is 20~22 DEG C of hatching first week, hatches 23~25 DEG C of second week, keeps 26~28 DEG C afterwards, hatching starts young leech on the 23rd~24 day.Compared with prior art, in an incubator of the invention ovum cocoon hatch young leech time it is basically identical, place hatch soil, ovum cocoon is absorbed nutrient and moisturizing in the process of hatching, control temperature and humidity, improve leech incubation rate.
Description
Technical field
The present invention relates to technical field of aquaculture, especially a kind of leech hatching method.
Background technology
Leech, popular name leech, the growth and breeding in the freshwater of inland, be Chinese tradition extraordinary medicinal aquatic animal,
The traditional Chinese medical science is used as medicine after its dried product is brewed, has treatment apoplexy, hypertension, the clear stasis of blood, amenorrhoea, traumatic injury and other effects.Send out in recent years
Existing leech preparation has special efficacy in preventing and treating cardiovascular and cerebrovascular disease and anticancer aspect, with the deep development of leech medical value, its
The market demand potential is huge.Because wild leech natural resources falls sharply, carrying out artificial Scale dependency needs to hatch substantial amounts of children
Leech, the leech hatching method used at present, ovum cocoon hatch the Time Inconsistency of young leech, when causing part children leech to descend water, also
There is part children leech just to hatch completion, and leech incubation rate is low.
The content of the invention
Problem to be solved by this invention is to provide a kind of leech hatching method, and this method can make ovum cocoon hatch young leech
Time is basically identical, improves leech incubation rate.
In order to solve the above problems, the technical solution adopted by the present invention is：This leech hatching method, a kind of leech hatching
Method, it is characterised in that comprise the following steps：
A, the ovum cocoon that contemporaneity is formed is positioned in same incubator；
B, incubator bottom spreads the hatch soil that a layer thickness is 1.0~1.5cm, and the sharper one end of ovum cocoon is placed in into hatching upward
On soil, ovum cocoon be well placed after in the hatch soil that lid a layer thickness thereon is 1.5~2.0cm, be mixed with hatch soil its weight 2~
3% carboxyl chitosan, the humidity of hatch soil is 32~42%；
C, incubator is put into hatching house, and the relative air humidity for controlling hatching house is 65~75%；The temperature of hatching house is hatching
First week 20~22 DEG C, hatch 23~25 DEG C of second week, keep 26~28 DEG C afterwards, hatching starts young leech on the 23rd~24 day.
In above-mentioned leech hatching method technical scheme, more specifically technical scheme can also be：Hatch soil uses paddy soils
With sandy soil 6: 1~1.5 mixing by volume, hatch soil handles by boiling, is dried to and turns white, then broke 60~80 purposes into pieces
Mesh screen.
Further, in step B on the hatch soil covered with ovum cocoon one layer of moisturizing cotton of lid again.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
The ovum cocoon that contemporaneity is formed is positioned in same incubator by the present invention, and ovum cocoon hatches young leech in an incubator
Time is basically identical, places hatch soil, ovum cocoon is absorbed nutrient and moisturizing in the process of hatching, controls temperature and humidity,
Improve leech incubation rate.Hatch soil is handled using paddy soils and sandy soil 6: 1~1.5 mixing by volume, hatch soil by boiling,
The germ in hatch soil and worm's ovum are killed, avoids ovum cocoon from being corroded by courses of infection or disease pest, leech incubation rate is high.
Embodiment
With reference to specific embodiment, the invention will be further described：
Embodiment 1
A kind of leech hatching method, comprises the following steps：
A, the ovum cocoon that contemporaneity is formed is positioned in same incubator；Ovum cocoon is aubergine in first formed, a few hours
After be transformed into light red, eventually become purple；
B, hatch soil is prepared, hatch soil is handled by boiling, shone using paddy soils and sandy soil 6: 1 mixing by volume, hatch soil
Do the mesh screen for then breaking 60 mesh into pieces to turning white；The carboxyl chitosan of its weight 2% is added into hatch soil and is well mixed；
Incubator bottom spreads the hatch soil that a layer thickness is 1.0cm, and the sharper one end of ovum cocoon is placed on hatch soil upward, ovum cocoon pendulum
In the hatch soil that lid a layer thickness thereon is 1.5cm after putting well, the humidity of hatch soil is 32%, is covered again in upper covered with ovum cocoon
One layer of moisturizing cotton；
C, incubator is put into hatching house, and the relative air humidity for controlling hatching house is 65%；The temperature of hatching house is hatching first
In 20 DEG C of week, hatch 23 DEG C of second week, keep 26 DEG C afterwards, hatching starts young leech on the 24th day.
Embodiment 2
A kind of leech hatching method, comprises the following steps：
