Embodiment 1

[0011] On March 18, 2008, the species was selected, and the leeches were biennials with strong body and obvious genitalia as the kind of leeches, and 10,000 kinds of leeches were selected; Throw in a spawning pool of 100 square meters, feed 100kg of snails 2 days after planting, keep the water level in the spawning pool at a depth of 30cm, collect cocoon eggs manually 10 days after spawning, and divide them into two batches, with an interval of seven days between the two batches. 16,000 cocoon eggs were obtained for the first time, and 14,000 cocoon eggs were obtained in the second batch. Put the cocoon eggs into the incubator, spread a layer of wet soil 1.5cm on the bottom of the square incubator, then put the cocoon eggs on the wet soil, cover After putting on the cloth, cover the cloth with a layer of 2cm thick wet soil. There are holes around the incubator to keep enough air in the box; the indoor temperature is kept at 20°C and the humidity is 70°C. Half of the first batch...

Embodiment 2

[0013] On April 2, 2008, the seed selection was carried out. The leeches were three-year-old with strong body and obvious genitalia as the kind of leeches, and 5000 kinds of leeches were selected; Throw in a spawning pool of 50 square meters, feed 100kg of snails one day after planting, keep the water level in the spawning pool at a depth of 35cm, collect cocoon eggs manually 10 days after spawning, and divide them into two batches, with an interval of seven days between the two batches. , 8,500 cocoon eggs were obtained for the first time, and 7,000 cocoon eggs were obtained in the second batch. Put the cocoon eggs into the incubator, spread a layer of wet soil 1.5cm on the bottom of the square incubator, then put the cocoon eggs on the wet soil, cover After putting on the cloth, cover the cloth with a layer of 2cm thick wet soil. There are holes around the incubator to keep enough air in the box; the indoor temperature is kept at 25°C and the humidity is 75°C. Half of the fir...

Embodiment 3

[0015] Carry out seed selection on April 9th, 2008, and leech is that biennial body is strong, and genitalia is obvious as kind of leech, chooses kind of leech 8000; Carry out disinfection treatment with 2‰ potassium permanganate diluent then, carry out after 10 minutes Throw it into a spawning pond of 80 square meters, feed 100kg of snails 2 days after the throwing, keep the water level in the spawning pond at a depth of 40cm, collect cocoon eggs manually 10 days after spawning, and divide them into two batches, with an interval of seven days between the two batches. 12,000 cocoon eggs were obtained for the first time, and 11,000 cocoon eggs were obtained in the second batch. Put the cocoon eggs into the incubator, spread a layer of wet soil 1.5cm on the bottom of the square incubator, put the cocoon eggs on the wet soil, and cover the After cloth, cover the cloth with a layer of 2cm thick wet soil. There are holes around the incubator to keep enough air in the box; the indoor...

Abstract

The invention discloses an artificial breeding method for hatching leeches and raising seedlings of leeches, aiming to provide a method for hatching leeches and raising seedlings of the leeches, which has leech hatching rate as high as 95 percent, shortened seedling emergence period and concentrated seedling emergence. The method sequentially comprises the following steps: 1, breed selection; 2, leech breed disinfection; 3, breed input; 4, mating and spawning; 5, cocoon classification; 6, hatching in a hatching room; and 7, hatching and seedling emerging. The invention has shortened seedling emergence period of the leeches and high seedling emergence concentration ratio, is convenient to artificial breeding, ensures the quality and indirectly increases the output of the commodity leeches by 150 kg each mu, enhances the benefit by 2000-3000 yuan each mu, and the like.

Description

technical field [0001] The invention relates to a method for hatching and raising seedlings of leeches artificially cultured. Background technique [0002] The leech mentioned in this article refers to the wide-body leech. The wide-body leech is an important Chinese medicinal material in my country. It has been identified as one of the 35 traditional Chinese medicinal materials for promoting blood circulation and removing blood stasis in the Pharmacopoeia. And the effect of reducing swelling and detoxification. It contains hirudin, which is considered by the medical profession to be the most effective anticoagulant substance in its body. Hirudin has the functions of relieving arterial arm spasm, reducing blood viscosity, dilating blood vessels, increasing blood circulation, and promoting absorption of exudate, and can treat difficult diseases such as hypertension and myocardial infarction. With the continuous development of medicine, people pay more and more attention to th...
