Summary of the invention
The object of the present invention is to provide a kind of method is easy, incubation time is short, output is high raising output and the silkworm chrysalis Cordyceps sinensis cultural method of quality.
Technical solution of the present invention is:
A kind of silkworm chrysalis Cordyceps sinensis cultural method that improves output and quality, is characterized in that: comprise the following steps:
(1) the preparation of liquid spawn:
Liquid nutrient medium preparation: the component of following weight portion is mixed and made medium: 10 ~ 30 parts of glucose, potassium dihydrogen phosphate 1-5 part, magnesium sulfate 1-5 part, 5 ~ 10 parts of peptones, yeast soaks powder 2-5 part, vitaminB10 .1 ~ 0.5 part, 1000 parts, water;
The bacterial classification preparation: the liquid nutrient medium prepared is sub-packed in conical flask, 200 ~ 250 milliliters every bottle, sealing, under 120 ℃ ~ 130 ℃ conditions, sterilizing is 18 ~ 30 minutes; Take out medium after sterilizing, naturally cool to room temperature, under aseptic condition, access Cordyceps militaris spawn; Under 15 ~ 30 ℃, in shaking table, 5-10 days is cultivated in concussion;
(2) pupal cell sterilization:
Get fresh and alive tussah chrysalis, with alcohol-pickled 1-3 minute, take out and be put into ultraviolet sterilization 15-30 minute on superclean bench;
(3) inoculation:
Liquid spawn is injected in pupal cell to each pupal cell 0.1-0.5 milliliter bacterial classification with syringe;
(4) dark culturing:
The pupal cell of inoculation is divided in bottle, each bottle 3-5, be placed in constant incubator, cultivate 5-10 days for 18-25 ℃, after it is stiff, take out; Under natural daylight, 18-25 ℃, cultivate 5-10 days under air humidity 50%-65% condition;
(5) the pupal cell wound is processed:
Cut long 2-3 centimetre at the pupal cell outside of belly with scissors, the openning 2-4 bar of dark 2-4 millimeters long, then each pupal cell outside of belly is placed in blake bottle upward;
(6) light is cultivated:
Under natural daylight, temperature 18-25 ℃, continue to cultivate 25-30 days under air humidity 65%-85% condition;
(7) gather
When light is cultured to fruit body and grows to the 5-8 centimeter length, gathered.
When in step (1) prepared by bacterial classification, shaking speed is 120 rev/mins.
Step is pupal cell when sterilization (2), and the mass concentration of alcohol is 75%.
The present invention is when silkworm chrysalis ossifys latter 5-10 days, silkworm chrysalis is carried out to the wound processing, make the mycelia be enclosed in the silkworm chrysalis body touch air and light, processing not only can be shortened going out the grass time of silkworm chrysalis Cordyceps sinensis greatly like this, also can increase grass output amount simultaneously, make fruit body look more slightly more strong, maturation time is shortened greatly.Shorten to 40-50 days from being inoculated into the stroma maturation by normal 60-80 days, more than stroma quantity is increased to the 15-25 bar by the 3-5 bar, length can reach 7-10 centimetre, fruit-body color after oven dry is bright-coloured, neatly, quality is high, and output improves more than 25% than common cultural method.With traditional cultural method relatively this cultural method to have the grass time short, fruit body quantity is many, grows vigorous, growth cycle shortens, and not only can improve the output of Chinese caterpillar fungus, has also greatly shortened growth cycle, and economic benefit is improved significantly simultaneously.
Below in conjunction with embodiment, the invention will be further described.
