Embodiment Construction

[0015] A method for cultivating leeches in ditches is characterized in that it comprises the following steps:

[0016] (1) Selection and construction of breeding canals: The breeding canals are located in a place where irrigation is convenient, sheltered from the wind and facing the sun, and multiple parallel breeding canals are excavated in the shape of a "mountain". , 1m deep, the breeding canal is provided with an inlet and outlet, and an escape net is set around the breeding canal.

[0017] (2) Preparation before breeding: set a layer of river mud with a thickness of 20cm at the bottom of the breeding canal, place some pebbles with a diameter of 5cm on the river mud, and then disinfect with 100ppm potassium permanganate solution, and dry the sterilized breeding canal for 7 days. Leeches can be stocked by water injection. Before the water injection, some grate eye vegetables are planted at the bottom of the canal. After the water injection, some water hyacinths are planted,...

Abstract

The invention discloses a method for breeding leeches in a channel. The method comprises the following steps: choosing to build a channel; preparing before breeding; introducing a fine variety; carrying out daily management. The method adopts freshwater mussels and snails to partly replace blood feeds, so that the cost of the feeds can be effectively reduced; by adding vitamin k in fresh blood, the blood can be well solidified and is prevented from dissolving during feeding to avoid feed waste and water pollution; in management, the quality and temperature of water are strictly controlled to guarantee the growing environment of leeches, and the condition that leeches die of diseases in the breeding process can be effectively reduced; by adopting the method, the feed coast can be reduced by 30-40%, and the condition that leeches die of diseases can be reduced by 60-70%.

Description

technical field [0001] The invention relates to characteristic breeding industry, in particular to a method for cultivating leeches in ditches. Background technique [0002] Leeches, also known as leeches, are a kind of precious Chinese medicinal materials. They are traditional precious medicinal animals in my country. It is recorded in medical classics such as "Compendium of Materia Medica" that: leeches have a good effect on treating stroke and high blood pressure. The salivary glands of leeches contain "Hirudin" is a special drug for preventing and treating cancer; fresh leech saliva contains a kind of anticoagulant bacterium hirudin, which can resist ADP-induced thrombus formation, activate the cellulose system, and promote the resolution of established thrombus; Secretes a tissue aminating substance that can expand capillaries. Today's Chinese patent medicine made from leech as the main raw material has been put into mass production, and the supply is in short supply. ...
