Problems solved by technology

[0004] Summarize existing technology shortcoming and be 1, traditional wide-body golden thread leech overwintering method, survival rate is low and unstable (survival rate fluctuates at 40-70%), is greatly affected by external environment (as sudden rise and fall of temperature, water level variation , noise effects, vibration effects, etc.)
2. The traditional wide-body golden thread leech overwintering method, the leeches have a high proportion of emaciation, and the average annual weight loss rate is 40%
3. The traditional overwintering method of leeches has high labor costs when collecting them, which is more irritating to leeches and cannot adapt to the cocoon-producing environment, resulting in high mortality in the second stage.

Embodiment 1

[0030] A kind of wide-bodied golden leech winter low-temperature preservation method, the specific method steps are as follows:

[0031] (1) Design a new wintering model

[0032] 1) From the perspective of reducing the interference of the external environment on the overwintering of the leeches, the traditional outdoor overwintering environment is transformed into a stable indoor environment.

[0033] 2) In order to prevent the leeches from hibernating due to the sudden rise and fall of temperature, it is required that the ambient temperature in the overwintering room should be kept stable at 6°C, the optimum overwintering temperature of the wide-bodied golden line leeches.

[0034] 3) From the perspective of solving the habitat of the wide-body golden leech and heat preservation, the traditional mixture of soil and bricks is changed to fine sand.

[0035] 4) From the perspective of reducing labor costs, put fine sand or square sponges into permeable commercially available wo...

Embodiment 2

[0045] A kind of wide-bodied golden leech winter low-temperature preservation method, the specific method steps are as follows:

[0046] (1) Design a new wintering model

[0047] 1) From the perspective of reducing the interference of the external environment on the overwintering of the leeches, the traditional outdoor overwintering environment is transformed into a stable indoor environment.

[0048] 2) In order to prevent the leeches from hibernating due to the sudden rise and fall of temperature, it is required that the ambient temperature in the overwintering room should be kept stable at 8°C, the optimum wintering temperature of the wide-bodied golden line leeches.

[0049] 3) From the perspective of solving the habitat of the wide-body golden leech and heat preservation, the traditional mixture of soil and bricks is changed to fine sand.

[0050] 4) From the perspective of reducing labor costs, put fine sand or square sponges into permeable commercially available woven ...

Embodiment 3

[0062] A kind of wide-bodied golden leech winter low-temperature preservation method, the specific method steps are as follows:

[0063] (1) Design a new wintering model

[0064] 1) From the perspective of reducing the interference of the external environment on the overwintering of the leeches, the traditional outdoor overwintering environment is transformed into a stable indoor environment.

[0065] 2) In order to prevent the leeches from hibernating due to the sudden rise and fall of temperature, it is required that the ambient temperature in the overwintering room should be kept stable at 10°C, the optimum wintering temperature of the wide-bodied golden line leeches.

[0066] 3) From the perspective of solving the habitat and heat preservation of the wide body leeches, change the traditional mixture of soil and bricks into square sponges.

[0067] 4) From the perspective of reducing labor costs, put fine sand or square sponges into permeable commercially available woven b...

Abstract

The invention relates to a whitmania pigra breed reservation method, especially to a winter low-temperature breed reservation method of whitmania pigra. Influence of outside environment on overwintering of whitmania pigra is changed to solve problems in habitat and thermal insulation, an overwintering container is novel in design, and thus, the overwintering survival rate of whitmania pigra is improved greatly, and the emaciation rate is reduced. Overwintering technology of whitmania pigra is explored deeply and created so as to solve the problem of increasing shortened and degenerated seed sources in the scaled whitmania pigra culturing process, the cost is reduced for farmers, profit is provided, and the present situation of shortage of whitmania pigra can be changed.

Description

1. Technical field [0001] The invention belongs to the technical field of wide-bodied golden leech, in particular to a method for preserving seeds of wide-body golden leech in winter at low temperature. 2. Technical background [0002] The broad-bodied Rhizoma genus belongs to the genus Annelida, the class of Hirudophylum, the order of Hirudidae, and the family of Rhododendronaceae, also known as the leech. It is a traditional Chinese medicinal material in my country. Clinically, it is mainly used to treat cardiovascular diseases, hyperlipidemia, gynecology, andrology, internal medicine and other diseases. [0003] Due to the high medicinal value and economic value of the wide-bodied golden leech, the demand for the wide-bodied golden leech in the pharmaceutical industry has increased year after year. In recent years, wild leeches have been affected by the pollution of pesticides, chemical fertilizers, and industrial waste. Man-made unrestrained fishing of leeches has led to...
