Abstract

The invention discloses an artificial domestication method for wild leeches. The method mainly comprises the following procedures of: selecting seeds, feeding, laying cocoons indoors, hatching indoors, breeding seedlings, and thus breeding high-quality leeches. The breeding technology is simple and advanced; by selecting the high-quality variety and adopting the scientific breeding method, the breeding efficiency is high; and by adopting the unique method of 'laying cocoons indoors and hatching indoors', the growth of the leeches is greatly quickened, and the growth period from the seedlings to the finished leeches is shortened.

Description

The artificial acclimation method of a kind of wild leech
Technical field
The present invention relates to the artificial acclimation method of a kind of wild leech, belong to cultural technique field.
Background technology
Leech is commonly called as leech, is the indispensable important source material of China's traditional Chinese medicine treasure-house, in all age by people, is referred to as to get rid of illness and rescues people's good medicine, and along with the development of domestic and international medical science, clinical practice is more extensive.Early on the books in China medical science masterpiece < < Compendium of Materia Medica > >, not only medical value is higher, and modern science and technology is found to produce health care, cosmetics, therefore, its personal value of leech has the title of " soft gold " " ginseng in water ".Wild leech is because being subject to the impact of agricultural chemicals, chemical fertilizer, industrial pollution in recent years, natural resources reduces day by day, wild leech faces extinction, therefore, leech is propagated artificially extremely urgent, for this situation, we several times grope and study, with regard to wild leech, take domestication, indoor product cocoon and hatching unique technology, successfully use for reference and promote in locality.This innovation, makes much to cultivate that fan is consistent with numerous raisers feeds back, respond well.This has not only solved leech demand and supply contraction outstanding problem, and is new aquaculture industry development developing Liao Xinzhi road, rural area.
China has been engaged in a lot of areas the production of hirudiniculture industry, but slower development, success precedent is few, problem basic, no matter propagate artificially or naturally cultivate stereotyped " outdoor product cocoon and the hatching " conventional method that mostly adopted, but owing to being subject to the impact of outer border wet weather, cold spell in spring, microthermal climate, also have the natural enemies such as outer border yellow weasel, mouse, frog, worm ant to encroach on, not only produce cocoon rate low, and injures and deaths are very serious.Particularly natural, ecological cultivation, cannot produce cocoon especially, and the one, breeding period, kind leech was got less than enough foodstuffs, caused malnutrition, and produced less cocoon or do not produce cocoon; The 2nd, the grasp of bound pair water quality, water temperature, water level is outside difficult to regulate, and planting leech does not have stable seeking a spouse and mating favorable environment in the external world; The 3rd, and make a small amount of ovum cocoon of output also can be immersed in water after-tack and death.Meanwhile, by outdoor river, a small amount of seedling of location, Deng You water source, pond survival almost also sucks by natural enemies such as swamp eel, frog, snake classes; The 4th, the leech product phase of incubating meets the special climates such as cold spell in spring low temperature again, cannot produce especially cocoon hatching, so traditional outdoor product cocoon or natural world product cocoon hatching m are sometimes almost nil.
Summary of the invention
In order to alleviate shortcomings and deficiencies of the prior art, the object of the present invention is to provide the artificial acclimation method of a kind of wild leech, cultural technique of the present invention is simple, advanced, selects the kind of high-quality and the cultural method of the science of employing, and cultivation efficiency is high.
The present invention adopts following technical scheme to achieve these goals:
The artificial acclimation method of wild leech, is characterized in that comprising the following steps:
(1) seed selection: at the beginning of April in the last ten-days period in March, temperature is 15 ℃ of left and right, and selecting weight is above individual large, the great-hearted healthy leech of 25g, then puts into the domestication intensive culture pond through lime stone sterilization;
(2) feeding: in domestication intensive culture pond, drop into spiral shell, freshwater mussel foodstuff, every square of 0.4-0.6kg, in control pond, 18 ℃-25 ℃ of temperature, raise and train as 10-15 days, and during raising and train, day and night temperature is not less than 16 ℃, and 11-12 point will be observed water temperature situation surely every night;
(3) indoor product cocoon: can adopt two kinds of methods, the first is indoor block pond method, the second is that vacuolar membrane case produces cocoon method;
(4) indoor hatching: young leech is quantitatively cased, control cabinet subsoil bed thickness 2-3cm, air humidity 65%, 25 ℃ of soil layer humidity 30%, temperature, emerge for 13-18 days;
(5) seedling culture: first pond is put into quicklime in intensive culture pond and sterilize, soak and change new water after 2-3 days, water level will keep 38-42cm, in pond, must load onto oxygen increasing pump, and build standby heat preservation greenhouse, water surface top, pond is put into the water weeds such as weter hyacinth, water lettuce in advance, after put into young leech, children leech enters first three sky, pond and does not ingest, within three days, drop into and be crushed to meat pasty state spiral shell, freshwater mussel afterwards, through the intensive culture management of 23-28 days, young leech can grow to 6-7 centimetre, finally leech is assigned in culturing pool and has been raised equably.
The artificial acclimation method of described wild leech, is characterized in that: described domestication intensive culture pond is for selecting north-south, and wide 3 meters, length is suited measures to local conditions, and the high 120cm in pond more than water level control 60cm, has built heat preservation greenhouse simultaneously.
The artificial acclimation method of described wild leech, is characterized in that:, for every square, domestication intensive culture pond is by 1.5kg quicklime full pool spilling head, soak after 2-3 days in the domestication intensive culture pond of described lime stone sterilization, will in pond, clean up, and then puts into fresh water.
The artificial acclimation method of described wild leech, it is characterized in that: described indoor block pond method is for selecting heat-insulating property better to produce pond, produce pond surrounding and can suitably spill a quicklime defence, soil layer humidity is 10-15 ℃, indoor temperature is controlled at 23-28 ℃, every square metre enters pond by kind of a leech 18-22kg, and cocoon is produced in the vaporific moisturizing of watering can for 9-11 days; It is the vacuolar membrane case of selecting through lime water sterilization that described vacuolar membrane case produces cocoon method, drops into kind of a leech 7-8kg.
The artificial acclimation method of wild leech, is characterized in that: during described indoor product cocoon, ovum cocoon foam-like differs in size as pellet, has the little young leech embryo in 15-50 interval in each cocoon; During described indoor hatching, every kilogram of 700 cocoons are standard, specifically observe seedling color and determine, and peony is moulding seedling; During described seedling culture, from ovum cocoon climbs out of, the about 1-2cm of length is that peony can enter pond and cultivates.
Beneficial effect of the present invention:
Cultural technique of the present invention is simple, advanced, select the kind of high-quality and the cultural method of the science of employing, cultivation efficiency is high, " indoor product cocoon, the indoor hatching " unique method simultaneously adopting, greatly accelerate leech growth rate, also shortened the growth cycle of seedling to finished product leech simultaneously.
Embodiment
Embodiment 1: the artificial acclimation method of wild leech, comprises the following steps:
