Description
Technical field
The present invention relates to cultural technique field, specifically a kind of cultural method of selenium-rich cray.
Background technology
Cray, also referred to as Procambius clarkii, red crayfish and freshwater crayfish.Cray meat flavour is delicious, nutritious, is high
Albumen, low fat and high-energy, nutritious health food, because of its omnivorousness, the speed of growth it is fast, it is adaptable and in locality
Absolute competitive advantage is formed in ecological environment.Its scope of ingesting includes pasture and water, algae, aquatic insect, spoil etc., food
Thing is also killed each other when deficient scarce.
Cray has become Important Economic breed variety in China in recent years.As consumer is recognized freshwater crayfish
To know and the extensive publicity of media is promoted, freshwater crayfish food generally enters restaurant, hotel, supermarket and Domestic dining table,
Cray demand is very vigorous, because overfishing, wild resource famine, commercial sized prawn quality are uneven；With regard to southwestern ground
For area, cray source of goods deficiency, in the winter time substantially without finished product shrimp；And it is that ditching formula is extensive foster that cray aquaculture model is most
Grow, rice field is supported altogether etc., per mu yield is not generally high.
In recent years, the cognition with everybody to healthy living, the especially organic food rich in selenium element, vegetable melon and fruit obtain
Everybody extensive favor is arrived.Show according to the study, in known chemical element, selenium is health member necessary to growth in humans
Element, its main function are：1. there is very strong oxidation resistance；2. pair some carcinogenic substances have stronger antagonism；
3. the normal configuration and function of cardiovascular system can be maintained, being capable of prevention of cardiovascular disease, the protection organs of vision；4. it can protect
Vegetative cell is repaired, there is removing toxic substances, toxin expelling, antipollution feature；5. that improves red blood cell takes oxidability, radioresistance；6. improve
Body immunity.
The content of the invention
It is an object of the invention to provide a kind of cultural method of selenium-rich cray, this method can accelerate cray growth hair
Educate, strengthen the vitality and disease resistance of cray, ensure the delicious meat of cray, without hormone and rich in necessary to human body
Selenium element.
Realize that the technical scheme of the object of the invention is：
A kind of cultural method of selenium-rich cray, comprises the following steps：
