Two, medical function of the leech
The leech is a medical aquatic products animal of special type , have many kinds of medical functions in medical science , being used as medicine can treat many kinds of diseases . If there is a kind of plain leech in the leech saliva, can suppress the activation of the blood enzyme , according to the records of relevant materials, the leech usually suppresses the fibrin ferment , namely has prevented the fibrinogen from forming the fibre protein, thus suppressed the forming of the thrombus. The leech includes and divides the blood circulation which contributes to replantation of a severed limb in the body, can improve operation success rate , dispel the sequelae . Ancient medical science utilizes this characteristic of the leech, suck the traumatism patient's suppuration blood with it, achieve the goal of clearing up stasis of blood; The worm body after the department of internal medicine of Chinese medicine will be dry steeps and makes medicines, treats silt lump , blood silt , menorrhoea , injuries from falls, fractures, contusions and strains ,etc.. Modern medical science is it prove leech is it prevent and cure heart brain blood vessel disease and resist cancer have specially good effect to use for to study further. With leech medical constant development of range , compound with leech especially produce prevent heart brain Chinese patent drugs , blood vessel of disease from increase gradually in recent years. Such as Shanxi, Shaanxi, Hebei, Henan, Heilongjiang, Jilin, Guangdong , Hong Kong a large number of pharmaceutical factory use whom leech produce happy to reply health dissolve the capsule, cure bolt soup , Korea S. paralysed speed health , is it promote blood circulation capsule , chase silt invigorate blood circulation capsule , easy blood coherent injectio ,etc. cured heart brain blood vessel disease disconnected patent medicine to invigorate blood circulation while being instant
Three, cultivate leech's market prospects Because the leech is a kind of valuable medical resource, have many kinds of medical functions in medical science , it is traditional Chinese medicinal materials of animal nature very worth developing . With the development of aging population, the heart brain blood vessel patient increases (the incidence of high blood pressure , heart disease accounts for 2-5% of the crowd), adding people's preference for the traditional Chinese medicine products, the demand for leech will increase further. Up to more than 250 tons to the aggregate demand of leech's dry product domestic and internationally in 1997 according to " China's animal husbandry aquatic products news newspaper " report on December 6 , 1998, and the supplying amount is only 150 tons actually, still have 100 tons of gaps . Relevant experts statistics show , leech's shortage amount will be up to 300,000 kilograms by the end of 1999. Because the imbalance between supply and demand is greater and greater, cause prices to go up constantly, the price of the purely clear smuggled goods has been already by about 80 yuan per kilogram in last autumn, rising present about 150 yuan per kilogram, its amount of the increase rose by 87.5%, this kind of situation will not take a favorable turn in a short time.
The reason causing leeches of upward price comes from several respects, on the other hand it is that some pharmaceutical factories of hinterland and Hong Kong are relatively large in demand for leech; Another on one hand the American-European consumer market is very big, in recent years, Japan , South Korea , Southeast Asian various countries import leeches from our country in a large amount, cause the domestic demand for leech to double and redouble; Third , because use agriculture chemical , chemical fertilizer and pollution of the environment of chemical discharge of industrial wastes in a large amount in recent years, cause wild leech resources to fall sharply; Fourth , because propagated leeches artificially and just just started at home, there were few plants of leech with scale .
to begin already.
It is easy to propagate leeches artificially
The leech has a good adaptability, it is strong to able to bear hungry ability , has extremely strong disease-resistant strength , so raise leeches and is not restricted by regional condition artificially, but the pool is raised , the hole is raised , the jar is raised , the barrel is raised etc.. With water planktonic organism , little insect , field snail , river clam , animal as raw materials clot , earthworm , rotten bone of earth ,etc. fodder, throw something and feed once every week. Whether put in a suitable place to breed density generally. The number of young leech is 10000 for each cubic meter surface of water; Cheng Zhi is 5000 for each cubic meter; Plant about 500 for each cubic meter leeches, the hole pool , ditch cultivate and put 2000 in a suitable place to breed and plant leeches with each mu surface of water. Family can cultivate the way to cultivate according to the hole pool , build into a pool , high 70-80cm of pool of brick, long 200cm, wide 120cm, the bottom of the pool paves bricks, spreading 15-20cm earth, the pool wall cement, some stones , pasture and water , branch ,etc. are put in the pool, setting up and throwing the material platform, it is should be lower than 3-5cm above water to throw the material platform, the bottom of the pool reserves and drains off water holes, about 30cm of depth of water in the pool, there are canopies on the pool top (rain-prooves are sun-proof), put a kind of 200 leeches in a suitable place to breed in every pool, can divide the pool to cultivate to treat the young leech long. So propagate leeches artificially and does not account for the labour , raise management extensivly and simply , the fodder is with low costs, the breeding potential is high , silent and tasteless and pollution-free, with little investment, such characteristics as with instant effect.
Five, propagate leech's benefit analysis artificially
The leech is the her-maphroditism , allogamy , each one plants leeches to breed , can breed 2-3 times every year. If there are conditions , can control the temperature and cultivating , control the temperature in 20-28°C, help leeches to grow fast, and can break and hibernate and is used to , the breeding amount obviously improves, lay eggs and can be up to 5 times at most. Plant according to each leech breed 2-3 every year , lay eggs callus is it calculate to have 8 more average , each can hatch appear young leech 40 equally in the callus every year, can breed to plant leeches every year each one according to 90% on average in survival rate: 1*8*40*90% =288, each kilogram plants about 80-100 leeches, can breed to plant leeches every year each kilogram: *100 for 288 =28800. The young leeches produced can grow into the goods leech in 6 months. About 100 of fresh product for each kilogram, it is 14.3% that the fresh product leech rolls over to the rate; Whether namely 7 fresh product is it can win 1 of dry product to dry, each plant leech is it can win dry product to breed every year. 28800 ÷ and 100 ÷ and 7 kilograms =Whether 41, sell at dry product price of 120 yuan of each kilogram , raise one plant leech can obtain gross profit every year each time. *120 yuan for 41 kilograms / kilogram =4920 yuan, is it invest to deduct and raise the cost , can obtain about 4000 yuan of net income . If a raiser raises 10 kilograms and plants leeches, can obtain net income of 30,000-40,000 yuan every year, and input, circulation is bred , benefited every year. So artificial to raise leech whether the masses of countryside , urban residents and first-selection of laid-off worker get rich the project.
