Embodiment Construction

[0025] The technical solution provided by the invention mainly includes: preliminary preparation of the paddy field cultivation system → construction method of the symbiotic system of leeches, snails and aquatic plants → maintenance and management of the symbiotic standard rough cultivation system → harvesting of leeches.

[0026] Concrete implementation process is as follows: leech seed and snail class and waterweed symbiosis standard roughly cultivate method, comprise the following steps:

[0027] a. Preliminary preparation of the standard rough cultivation and breeding system: including ①. Paddy field division: divide the flat paddy field breeding area into a breeding area and a water quality purification area; ②. Add hydroponic water to regulate and optimize water quality; ③. Kill harmful organisms;

[0028] b. Construction of leech seedlings, snails and aquatic plants symbiosis standard rough cultivation system: including ①. planting aquatic plants, strengthening the water...

Abstract

The invention discloses a leech fry, snail and aquatic plant commensalism intermediate breeding method and belongs to the technical field of aquaculture. According to the method, an ecotype leech fry commensalism breeding system is built, small snails and / or zooplanktons and / or nutrients are adopted as fodder of young leeches, the breeding system is stabilized through the purification capacity of aquatic plants, deterioration of water quality is avoided, the young leeches obtain rich nutrition through composite collocation and application of small snails, zooplanktons and nutrients, leech fries are good in activity, rapid in growth and low in casualty rate, the situation that as young leeches live in groups and climb to be groups seriously, serious death is caused when the young leeches can not obtain fodder is avoided, the rate of survival is improved in the leech fry breeding stage, the method is simple in process, technical feasibility is achieved, breeding enterprises and farmers can use the method conveniently, the technical advantages of maintaining good and stable breeding environment, reducing the risks of leech fry death and the like are achieved, and the method has wide application prospects in the field of national leech breeding.

Description

Technical field: [0001] The invention relates to a method for cultivating leech seedlings, in particular to a method for cultivating standard leech seedlings with uniform specifications by adopting fence technology and water environment ecological control technology to establish an imitation ecological environment suitable for the growth of leech seedlings. Background technique: [0002] The dried whole body of WhitmaniapigraWhitman, an animal of the leech family, is one of the main basic raw materials of the medicinal material leech included in the 2005 edition of the "Chinese Pharmacopoeia". Due to environmental and other factors, the wild resources of leeches have been decreasing day by day. In 1984, leeches were included in the International Red Book of Animal Protection. Since the leech breeding industry is a new breeding industry, the breeding foundation is not solid, the technology is not perfect, and the breeding output is generally not high, most of which have an ou...
