Abstract
A kind of ditch formula cultural method of leech, comprising steps of ditch setting steps: choose have abundant water resources, be leeward, around not no pollution sources place or field, 80-120 centimetres wide, the deep 30-50 centimetres ditch for constituting circulation flowing water is dug in place or field；The processing step in ditch: the ditch dug is cleaned out, disinfection of splashing while hot after being dissolved in water with 0.2-0.5 kilograms of quick lime with every square metre by ditch surface area, is allowed to dry water after impregnating a week, is reinjected clear water, then put and grow leech.Its advantage is that shortening brooding time, young leech can be hatched at 25 days or so, hatch high survival rate.Its advantage is that natural flows environment can be simulated, it is suitble to leech growth, three-dimensional kind can be carried out and grow and cultivate, leech high survival rate.
Description
Technical field
The present invention relates to artificial culture technology field, in particular to the ditch formula cultural method of a kind of leech.
Background technique
The leech of artificial breeding hatching at present, is all made of and is cultivated in big pond, although being gone out using one side water inlet another side
Water changes water mode, but since pond is big, can not form the effect of natural flows, big with leech natural growing environment difference, directly
Connect the culture efficiency for influencing leech.
It is an object of the invention to provide one kind to provide the leech of optimum leech growing environment with simulating natural environment
Ditch formula cultural method.
Solution of the invention is such that
A kind of ditch formula cultural method of leech, comprising steps of
(1) ditch setting steps: choose have abundant water resources, be leeward, around not no pollution sources place or field, in place or field
In dig wide 80-120 centimetres, the deep 30-50 centimetres of ditch for constituting circulation flowing water；
(2) processing step in ditch: the ditch dug is cleaned out, by ditch surface area with every square metre with 0.2-0.5 thousand
Gram quick lime be dissolved in after water disinfection of splashing while hot, be allowed to dry water after impregnating a week, reinject clear water, then put and grow leech.
More specific technical solution further include: further include anti-escape step: anti-escape ditch, anti-escape furrow width are set on ditch periphery
It is 12-18 centimetres, 8-12 centimetres high, high 70-90 centimetres of fence is surrounded with the fine-structure mesh less than 80 mesh, and ditch is placed in escape-proof fence
It is interior.
It is further: to further include anti-natural enemy step: protective net being installed above ditch or above escape-proof fence and is covered
Lid, to prevent natural enemy.
Further: in the ditch setting steps, ditch is arranged to the ditch of comb teeth-shaped, be formed between adjacent ditch wide
Spend the native ridge of protrusion at 80-120 centimetres.
Further: crops kind on the native ridge of the protrusion grows crops.
It is an advantage of the invention that natural flows environment can be simulated, it is suitble to leech growth, three-dimensional kind can be carried out and grow and support
It grows, leech high survival rate.
Specific embodiment
Specific implementation method of the invention is as follows:
Selection has abundant water resources, is leeward, around the not place of pollution sources or the field ditch Li Wa, single ditch is 1 meter wide, deep 40
Li, the native ridge of protrusion of middle one meter of width in interval, then another is dug, every bar ditch length is unlimited, but every bar ditch is needed to be connected to, and forms ditch
Canal communicates, and recycles flowing water, and ideal ditch is comb teeth-shaped ditch.
It cleans out, every square metre with 0.3 kilogram of quick lime, is dissolved in after water disinfection of splashing while hot, puts after impregnating a week
Solid carbon dioxide reinjects clear water, puts some stones, and then the imitative field scene such as tile, bamboo puts and grows leech, periphery is set up defences again escapes ditch,
It is 15 centimetres of furrow width, 10 centimetres high, it is made a circle 80 centimetres of high fences with 80 mesh fine-structure meshes, carries out anti-escape, fishing is worn with iron wire again in high-altitude
Net covering, can anti-natural enemy, irrigation canals and ditches aquaculture cost is cheap, easy, between intermediate sulcus and ditch can also planting vegetable, melon and fruit, in ditch also
Non- predacious fish, such as loach, variegated carp, crucian etc. can be cultivated, three-dimensional culture is reached, increases income.
