Artificial leech breeding technique

Abstract

The invention relates to an artificial leech breeding technique which is characterized in that a water inlet and a water outlet are formed in opposite corners of a culture pond, stones and tree twigs on which leaches inhabit are put at the bottom of the culture pond, preferably 500 kg of whifmania pigras for artificial breeding are fed into each mu of the pond, the leaches mainly take blood of snails, clams, frogs, turtles, earthworms and mammals, various blood-mixed feed, grass powder or even manure can be adopted for artificial breeding, about 30 kg of alive snails can be fed into each mu of the pond at one time, as the artificial breeding density is high, the water needs to be kept clean, a certain dissolved oxygen amount needs to be ensured, water needs to be appropriately replaced when the temperature of water is high in summer, the leaches are rapid to reproduce and high in regenerative capacity, the last ten-day of April and the middle ten-day of June are the egg laying period, the eggs of the artificially bred leaches are laid in soil in water near a breeding pond platform, a quiet environment shall be provided during the egg laying period, people shall walk on the banks as less as possible, and after being laid, the eggs of the leaches are dug out for artificial incubation, and then the leaches can be captured and processed.

Description

Technical field: [0001] The invention relates to a technique for artificial breeding of leeches. Background technique: [0002] Leech, scientific name leech, is a precious medicinal material. Many countries have the habit of using leech as medicine since ancient times. Its dried products are processed and used in traditional Chinese medicine. It has the effects of treating stroke, high blood pressure, clearing blood stasis, amenorrhea, and traumatic injuries. The widespread use of pesticides, coupled with the predatory capture of leeches in recent years, has reduced the resources of wild leeches, which is far from meeting the needs of medicinal materials. Due to the shortage of medicinal materials, artificial breeding is now carried out in many places. Invention content: [0003] The present invention relates to a kind of artificial cultivation technology of leech, it is characterized in that the artificial cultivation technology of leech: [0004] 1. Set the water inlet ...
