（2）Well water after disinfection is put into glass box, water level reaches the height of glass tank wall 1/3-1/2, then to glass box
Middle addition nutrient solution, stirs evenly, and wherein nutrient solution is made of the component of following parts by weight：12-15 parts of saline cistanche, iron amaranth 10-
13 parts, 11-14 parts of Chinese violet, 8-10 parts of rabdosia lophanthide, 7-10 parts of Semen Cuscutae, 6-10 parts of chingma abutilon seed, 360-400 parts of water；
（3）In annual the first tenday period of a month in May, 350-400 bar children leech is launched per case；
（4）Control the daily light application time of leech for 4-6 it is small when, after illumination, glass box is moved to closed interior, is thrown into water tank
Bait is put, wherein bait is made of the component of following parts by weight：40-50 parts of spiral shell, 4-6 parts of pearl viburnum fruit, 7-10 parts of cassia seed,
3-5 parts of fishbone dust；
（5）Every 3-4 days, water is once changed, after changing water, continues to add nutrient solution into glass box.
Specifically, above-mentioned steps（1）In, the inner wall of glass box is frosted inner wall.
Specifically, above-mentioned steps（2）In, the volume that nutrient solution adds is the 1-5% of water volume in glass box.
Specifically, above-mentioned steps（2）In, nutrient solution is made of following methods：After boiling is boiled, meat desert is added thereto
Rong, iron amaranth, Chinese violet, rabdosia lophanthide, Semen Cuscutae, chingma abutilon seed, after decocting 80-100min using small fire, are obtained by filtration filtrate, will
After filtrate is cooled to room temperature, nutrient solution is made.
Specifically, above-mentioned steps（4）In, bait is made of following methods：Spiral shell, pearl viburnum fruit, cassia seed are mixed
Afterwards, after being ground into the powder that average grain diameter is 3mm, fishbone dust is added thereto, and after being mixed evenly, bait is made.
From the above technical scheme, it can be seen that the beneficial effects of the invention are as follows：
The cultural method provided by the invention for shortening the hirudiniculture cycle, easy to operate, of low cost, the breeding process of leech
In, survival rate is high, and can effectively shorten the culture-cycle, and the yield of leech is high.The present invention cultivates leech using glass box, thoroughly
Photosensitiveness is good, it is ensured that leech has sufficient illumination, improves the vigor of leech, improves the feed intake of leech, and then accelerate
Its growth speed, while glass box is easy to observe the animation of leech, can find and remove in time disease leech, dead leech, adopt
With the glass inner wall of frosted, effectively leech can be avoided to escape using sucker suction；Nutrient solution provided by the invention, can be effective
The secretion of leech appearance mucus is stimulated, and then promotes the immunity of leech, reduces the illness rate and the death rate of leech, at the same time
Nutrient solution produced by the present invention, moreover it is possible to which the poisonous ammonia nitrogen substances in effective conversion water body, lift the security of water body；The present invention
After the bait of offer, pearl viburnum fruit and cassia seed synergistic effect, the feed intake of leech can be effectively lifted, promotes the digestion of leech
Absorb, and the speed of growth of leech can be lifted, and then improve the yield of leech.
