Embodiment 1

[0022] Embodiment 1 leech seedling cultivation

[0023] (a) Hatching: in late April, leech eggs were put into an incubator for hatching. The incubator was composed of a foam box and the hatching matrix laid in the foam box, and was observed several times a day;

[0024] (b) Emergence: When small black spots appear on the leech eggs, place the leech eggs with small black spots on a foam plate with a length and width of (5-10) cm×(5-10) cm, so that the foam plate floats on the On the water in the nursery pool, cover the leech eggs with absorbent cloth, and immerse the two or four sides of the absorbent cloth in the water; after 15-20 days, all the leech eggs will emerge, and the emerging leeches will enter the water in the nursery pool by themselves, and take out the foam plate and absorbent cloth;

[0025] (e) Growth and daily management of leech seedlings: leech seedlings grow in nursery ponds, keep greenhouse temperature at 25-30°C, humidity at 40-50%, water temperature in se...

Embodiment 2

[0026] Embodiment 2 leech seedling cultivation

[0027] (a) Build a leech seedling raising system: the leech seedling raising system includes a greenhouse and a seedling pond provided in the greenhouse, and the bottom of the seedling pond is provided with a culture substrate;

[0028] (b) Prepare the incubator: the incubator consists of a foam box and the soil laid in the foam box;

[0029] (c) Hatching: In late April, put the leech eggs into the incubator in the greenhouse to hatch, keep the temperature of the greenhouse at 28-32°C, and the humidity at 40-50%, and observe several times a day;

[0030] (d) Emergence: When small black spots appear on the leech eggs, place the leech eggs with small black spots on a foam plate with a length and width of (5-10) cm×(5-10) cm, so that the foam plate floats on the On the water in the nursery pool, cover the leech eggs with absorbent cloth, and immerse the two or four sides of the absorbent cloth in the water; after 15-20 days, all t...

Embodiment 3

[0032] Embodiment 3 leech seedling cultivation

[0033] (a) Build a leech nursery system: leech nursery and culture system, see Figure 1 to Figure 3 , including a greenhouse (1) and a seedling pond (2) set in the greenhouse (1), the greenhouse (1) is composed of a top layer and a side wall, the bottom of the seedling pond (2) is provided with a culture substrate, and the seedling pond (2) The cocoon-producing bed (3) and the operating platform (4) are arranged in parallel intervals, and the water pipes (5) and the nursery pool ( 2) A water inlet and outlet (6) is provided at a corner away from the water passage pipe (5), and the water inlet and outlet (6) is a cubic cage with an upper opening. The top layer of the greenhouse (1) is composed of an upper layer of sunshade net (11) and a lower layer of film (12). The refractive index of the sunshade net (11) is 60-80%, preferably 70%. The film is polyethylene non-drip plastic, The cultivation substrate is soil. The greenhouse...

Abstract

The invention provides a leech fry raising method which comprises the following steps: 1) hatching: hatching leech eggs in a hatching box, wherein the hatching box comprises a foam box and hatching substrate spread in the foam box; 2) obtaining fries: when small black spots appear on the leech eggs, putting the leech eggs with small black spots onto a foam plate, floating the foam plate on pond water of the fry culturing pond, covering the leech eggs with the water absorbing cloth, immersing two edges or four edges of the water absorbing cloth into the water, causing the leech eggs to completely hatch in 15-20 days, causing the hatched leeches to automatically enter the pond water of the fry culturing pond, and taking out the foam plate and the water absorbing cloth; and 3) raising the young leeches: raising the young leaches in the fry culturing pond. The leech fry raising method disclosed by the invention has the advantages of high survival rate of young leeches, is simple to operate and is suitable for large scale production.

Description

technical field [0001] The invention relates to a method for raising seedlings of leeches. Background technique [0002] Leeches are important Chinese herbal medicines in my country. It is recorded in "Chinese Pharmacopoeia" 2010 that leeches have the effect of "breaking the blood and stimulating the menstrual flow, removing blood stasis and eliminating lumps, and can be used for blood stasis amenorrhea, lame lumps, stroke hemiplegia, and injury from falls." , is the main raw material of many Chinese patent medicines for the treatment of cardiovascular and cerebrovascular diseases. The natural hirudin made from leech extract is the strongest natural specific inhibitor of thrombin among the known anticoagulant substances found in the world so far. It is very effective in dilating blood vessels, reducing blood viscosity, and increasing blood circulation. Significant; it has a good curative effect in the treatment of hypertension, stroke, coronary heart disease, arterial thromb...
