Problems solved by technology

At present, most of the breeding methods related to leeches are carried out in rice fields and ponds, and the breeding of leeches is seldom carried out in ponds.
Moreover, due to factors such as the natural environment and natural enemies, the hatching speed of leeches is 15-25 days, and the hatching rate is low, which seriously limits the extent of large-scale breeding of leeches

Embodiment 1

[0039] (1) Preparation of the incubator: spread the moist matrix made of newspaper, cardboard and foam on the bottom of the box with a thickness of about 6cm. Avoid too much water. The moisture content on the surface of the matrix is ​​10.5%-10.8%. Wet sponges with 10 grids are spread on the substrate, and then fresh leech egg cocoons excavated are gently put into the sponge grids, and then the incubator is covered with a shading cloth, and 10 eggs are hatched in each box Cocoon, three boxes in total;

[0040] (2) Artificial incubation process: put the incubator into a room at room temperature, soak the shading cloth with clean water, and then cover it completely on the incubator, and use a 200-watt incandescent lamp to simulate the sun directly above the incubator, half an hour later , insert the temperature and humidity meter carefully into the box, pay attention that the bottom of the thermometer cannot touch the bottom and the wall of the box, measure the temperature and h...

Embodiment 2

[0045] (1) Preparation of the incubator: Spread the moist matrix made of newspaper, cardboard and foam on the bottom of the box with a thickness of about 5cm. Avoid too much water. The moisture content on the surface of the matrix is ​​about 9.1-9.7%. Use a wet sponge with 10 grids to spread it on the substrate, then gently put the 10 fresh leech egg cocoons dug out into the grid of the sponge, and finally cover the incubator with brown glass. Hatch 10 egg cocoons, a total of three boxes;

[0046] (2) Artificial incubation process: put the incubator into a room at room temperature, and use a 300-watt incandescent lamp to simulate the sun directly above the incubator. After half an hour, carefully insert a thermometer into the incubator. Be careful not to touch the bottom of the temperature and humidity meter. The bottom and wall of the box, measure the temperature and humidity inside the box, make sure the temperature inside the box is kept at 18-22°C, and the relative humidit...

Embodiment 3

[0051] (1) Preparation of the incubator: spread the moist matrix made of newspaper, cardboard and foam on the bottom of the box with a thickness of about 7cm. Avoid too much water. The moisture content on the surface of the matrix is ​​about 11.0-11.5%. A wet sponge with 10 grids is spread on the substrate, and then 10 fresh leech egg cocoons dug out are gently put into the sponge grid, and finally the incubator is covered with brown glass, and each box is hatched. 10 egg cocoons, a total of three boxes;

[0052] (2) Artificial incubation process: put the incubator into a room at room temperature, and use a 500-watt incandescent lamp to simulate the sun directly above the incubator. After half an hour, carefully insert a thermometer into the incubator. Note that the bottom of the thermometer cannot touch the bottom of the incubator and On the wall of the box, measure the temperature inside the box. Be sure to keep the temperature in the box at 18-22°C and the relative humidity...

Abstract

The invention belongs to the field of culture, particularly relates to an artificial soilless leech hatching method and provides the artificial soilless leech hatching method aiming at improving leech hatching speed and hatching quantity. The artificial soilless leech hatching method comprises the steps of: A) collecting leech egg cocoons; B) preparing an incubator: 1) using materials with water absorbing and moisture preserving performance as mediums and flatly laying the mediums at the bottom of the incubator, wherein the surface water content of the mediums is 9-12 percent; 2) laying a latticed water absorbing and moisture preserving layer on the mediums, wherein the size of the lattices of the water absorbing and moisture preserving layer is suitable for putting a leech egg cocoon andthe water content of the water absorbing and moisture preserving layer is 121-130 percent; 3) putting the leech egg cocoons in the lattices of sponge; and 4) conducting sunshade treatment to the incubator; and C) hatching: controlling the internal temperature of the incubator to be 18-22 DEG C and the relative humidity to be 83-88 percent. By adopting the method to hatch leeches, the restrictionsof natural environments are avoided, the leech egg cocoons can be hatched intensively in a large scale, the hatching rate is greatly improved, the fry collection cost is saved and the effective utilization ratio of resources is improved.

Description

technical field [0001] The invention belongs to the field of breeding, and in particular relates to a method for artificially hatching leeches without soil. Background technique [0002] Leech is a general term for the class Hirrdinea of ​​the phylum Annelida in animal classification. There are about 500 species known in the world, divided into 4 orders. There are 2 orders, 8 families, 33 genera and nearly 100 species in my country. Among them, some species of the order Anoscillidae, Phyllididae, Phyllididae, and Lidaceae are closely related to the production and life of human beings. [0003] The 2010 edition of the Pharmacopoeia of the People's Republic of China contains leeches, a traditional Chinese medicinal material, which stipulates that leeches are the dried whole body of Hirudo nipponia Whitman, leech Whitmania pigra Whitman or Whitmania acronulate Whitman. . Leeches are important traditional Chinese medicinal materials, especially for the preparation of Chinese...
