The invention discloses a culture method of
selenium-enriched
cordyceps sobolifera conidial
powder. Firstly, separation, purification and identification are performed on
cordyceps sobolifera collected in a field to obtain
Paecilomyces cicadae (Miquel.) Samson, plate cultivation is performed to obtain single colonies, then, the single colonies are transferred to a
liquid medium for culture, a liquid secondary seed solution is obtained, the secondary seed solution is transferred to a composite culture medium containing organic
selenium fertilizer, the temperature is controlled to 15-35 DEG C, the
humidity is controlled to 60-90%, ventilation culture is performed for 4-6 weeks, and harvesting is performed to obtain
selenium-enriched
cordyceps sobolifera conidial
powder. Artificial
simulation is performed to obtain nutritional and growth conditions closest to the conditions needed by
cordyceps sobolifera wild environment, growth of
cordyceps sobolifera is not limited by season changes, the composite culture medium is closer to natural bamboo forest
cordyceps sobolifera wild environment, the breathability is good, the water absorption and moisturizing performance are excellent, a fruiting body grows rapidly,
spore head and conidial
powder of the fruiting body are abundant, thick,
solid, full, large in conidial powder amount, high in quality and easy to harvest, the content of selenium is 20-100 mg / Kg, the method is simple and low in cost, the
spore harvesting period is short, and industrial production can be achieved.
