Abstract

The invention discloses hatching equipment and method for leeches. The hatching equipment is characterized in that a collecting device (1), a hatching device (2) and a water spraying device (3) are included; the hatching device (2) is arranged in the collecting device (1), and the water spraying device (3) is arranged on the hatching device (2). The hatching method of the equipment is characterized by comprising the steps that the whole device is placed in a pool added with water of 4 cm to 6 cm, a zipper is pulled open in the hatching process, a layer of soil is laid on each layer of iron gauze, leech egg cocoons are flatly laid on the soil layers, then a layer of mud is laid on each layer of egg cocoons, and the mud is covered with towels or cloth; the humidity of the soil is checked every other 3-4 days, and if the humidity of the soil is low, a water source is opened to enable water to automatically flow into a wound U-type pipe and drop into the soil, and the humidity of the soil is kept; leech fry automatically crawl out of the cocoons and fall into a net cage with water at the bottom, the net cage is taken down, and the leech fry are placed in the pool for intensive culture.

Description

The incubation equipment of a kind of leech and method

Technical field

The present invention relates to a kind of leech incubation equipment, belong to special economic animal cultivation field.

Background technology

Leech is the general designation of Annelida (Annelida) Hirudinea (Hirrdinea), is commonly called as leech.It is the traditional rare traditional Chinese medicine of China, has promoting blood circulation and removing blood stasis, effects such as dissipating bind of stimulating the menstrual flow.Be usually used in hypertension, high fat of blood clinically, prevent the cardiovascular and cerebrovascular disease such as apoplexy, coronary heart disease.

Along with the pollution of environment is as the use of agricultural chemicals, weed killer herbicide etc., the germ plasm resource of leech is fewer and feweri.Therefore the breeding of leech becomes the core in whole hirudiniculture link.There is a lot of problems, the escape etc. of the collection of leech, the maintenance of hatching medium humidity, leech seedling in leech hatching simultaneously.Conventional method adopts and artificially collects leech seedling, and artificial water spray etc., consume a lot of labours virtually.

Chinese patent also discloses some leech propagation methods, as Chinese patent < application number >201310470033.8< denomination of invention > leech cocoon hatching m, be collect ovum cocoon on the basis of ovum cocoon maturation, operating process is many.Waste a lot of labours.

Summary of the invention

The technical problem to be solved in the present invention is: for the defect of prior art, the equipment that a kind of leech hatches is provided, the problem that the collection of the hatching of the leech cocoon in effective solution reproductive process, the humidity of hatching medium, leech seedling, leech seedling are escaped, to overcome the deficiencies in the prior art.

Technical scheme of the present invention is: a kind of leech incubation equipment, comprises gathering unit, hatching apparatus and water injector, and hatching apparatus is arranged at gathering unit inside, and water injector is placed on hatching apparatus.

Described gathering unit is the closed net cage that bolting silk net and slide fastener are made.

Described hatching apparatus is H-shaped sandwich construction, and every one deck steel wire and surrounding weld together.Surrounding utilizes angle steel to be welded.

Described water injector utilizes the flexible pipe with micropore to be coiled into U-shaped, under being bundled in wire netting, and is connected with external source by pipeline.

Utilize a hatching m for described equipment, whole equipment is put into the pond of the 4-6cm that adds water, during hatching, slide fastener is pulled open, at every layer of wire netting upper berth one deck soil, again Whitmania pigra Whitman spawns is laid in above soil layer, then at ovum cocoon upper berth one deck earth, covers towel or cloth; Check soil moisture every 3-4 days, as soil moisture is low, open water source and automatically flow into by water in the U-tube be coiled into, and instill in soil, keep soil moisture; Leech seedling climbs out of after going out cocoon naturally, and falling into bottom has in the net cage of water, takes off net cage and leech seedling is put into pond intensive culture.

Beneficial effect of the present invention: the effect of this equipment is the humidity of runing away, ensureing hatching process mesostroma solving leech seedling, the collection being convenient to leech seedling, and object is the damage of saving labour, reducing young leech, improves survival rate, saves farming site; This device utilizes net cage device, the leech hatching apparatus of hatching apparatus, water injector composition; Cheap, simple to operate.Be convenient to the factory management of leech hatching, save a large amount of manpower and materials; This device adopts the form of layering simultaneously, utilizes space, has greatly saved aquaculture cost, is easy to promote.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention;

Fig. 2 is hatching apparatus structural representation.

Embodiment

As shown in Figure 1, a kind of leech incubation equipment, comprises gathering unit 1, hatching apparatus 2 and water injector 3, and it is inner that hatching apparatus 2 is arranged at gathering unit 1, and water injector 3 is placed on hatching apparatus 2; Gathering unit 1 is the closed net cage that bolting silk net and slide fastener are made; Hatching apparatus 2 is H-shaped sandwich construction, and every one deck steel wire and surrounding weld together, and surrounding utilizes angle steel to be welded; Water injector 3 utilizes the flexible pipe with micropore to be coiled into U-shaped, under being bundled in wire netting, and is connected with external source by pipeline.Surrounding utilizes angle steel to be welded, and angle steel root edge can with steel wire close contact, better carry hatching medium.Edge utilizes the height of angle steel, is conducive to the accumulation of hatching medium.Hatching apparatus 2 top is the rock-steady structure of steel-pipe welding, as handle, is conducive to the movement of whole device.

Concrete method of manufacture and use thereof:

Adopt angle steel to weld formation hatching apparatus according to Fig. 1, adopt microporous hose to be coiled into n U-shaped, utilizing band to be fixed in below wire netting, and be connected with external source;

The net cage of ready-made band slide fastener is enclosed within outside hatching apparatus, and whole equipment is put into the pond of the 4-6cm that adds water;

During hatching, slide fastener is pulled open, at every layer of wire netting upper berth one deck soil, then Whitmania pigra Whitman spawns is laid in soil top, and then layer overlay soil on ovum cocoon, cover towel or cloth;

Checked soil moisture every 3-4 days, as soil moisture is low, open water source and automatically flow into by water in the U-tube be coiled into, and drip as in soil; Keep soil moisture;

Leech seedling climbs out of after going out cocoon naturally, falls into as bottom has in the net cage of water, takes off net cage and leech seedling is put into pond intensive culture.
