Artificial outdoor leech cocoon production and indoor hatching technology and application thereof

A technology of artificial chamber and leeches, applied in the field of animal husbandry, etc., can solve the problems affecting the survival rate of the leech seedlings that hatch first, the cumbersome operation of cocoon production and leech cocoon hatching, and the inability of leech seedlings to be cultivated in the pond in time, and achieve the goal of leech seedlings. The effects of clean seedlings, convenient management, and less workload

Problems solved by technology

[0005] Judging from the above-mentioned existing outdoor cocoon production and foam box hatching technologies, the existing cocoon production and leech cocoon hatching operations are cumbersome and labor-intensive, and because the cocoon production of leeches is not synchronized, the cocooning time of leeches in the later stage of incubation is inconsistent, and the leech seedlings cannot Timely culture in the pond will affect the survival rate of the first-hatched leech seedlings and the effect of later cultivation

Embodiment 1

[0031] Carry out the artificial propagation of wide-body golden leech according to the method of following steps:

[0032] (1) Cocoon production bed preparation:

[0033] Choose a leeward sunny pond, drain the pond water in winter, and disinfect the bottom of the pond with chlorine dioxide in late March, every 667m 2 The area dosage is 1㎏, and 5 days after disinfection, the bottom of the pool is made into multiple cocoon-producing beds. The cocoon-producing beds are rectangular with a width of 1.5m, and the cocoon-producing beds are separated by 50cm.

[0034] The production method of the cocoon bed is as follows: spread the soil in the interval area on the cocoon bed with a shovel, the center of the cocoon bed is slightly higher, and the average thickness of the soil is about 25cm. The cocoon production bed meets the ecological requirements for cocoon production by mating of wide-body golden leech, and the cocoon production bed is completely made of soil without other specia...

Embodiment 2

[0045] With reference to the steps and methods of Example 1, medical leeches are artificially cultivated, and the recovery rate of the leech-friendly leeches reaches more than 60%; about 10,000 leech seedlings can be collected from an average 500 g of cocoons.

Embodiment 3

[0047] With reference to the steps and methods of Example 1, the brown leeches were artificially cultivated, and the recovery rate of the leeches was more than 60%; about 10,000 leech seedlings could be collected from an average 500 g of cocoons.

Abstract

The invention discloses an artificial outdoor leech cocoon production and indoor hatching technology and application thereof. Outdoor pond clay serving as a matrix is used as a cocoon production bed, a nylon film covers the cocoon production bed to achieve heat preservation and moisture preservation, and when leech worms are found on the cocoon production bed, leech cocoons are immediately dug out and moved into a room for hatching, and leech hatchling collection is performed by adopting a specially-designed hatchling collecting device. By means of the artificial outdoor leech cocoon production and indoor hatching technology, the cocoon production amount of parent leeches is large, management during hatching is convenient, and the working amount is low. The leech hatchling collection and hatchling breeding in a pond can be timely performed, and the survival rate of later-period breeding can be improved.

Description

technical field [0001] The invention relates to the technical field of artificial breeding of leeches, and particularly discloses an indoor hatching technology for artificial cocoon production of leeches outdoors and an application thereof. Background technique [0002] Leech, commonly known as leeches, is a general term for annelids, leeches. Leeches are currently one of the main raw materials of drugs for the treatment of human and cerebrovascular diseases. With the continuous improvement of people's living standards, cardiovascular and cerebrovascular diseases have also become a common and frequently-occurring disease, seriously affecting human health. In this case, the market for leeches The demand continues to increase, and the wild resources of leeches cannot meet the market demand, so it is imperative to carry out artificial breeding of leeches. [0003] In the prior art, there are many researches on leech artificial breeding technology. For example, patent CN1017661...
