The cultivation method of bacteria and insects is to spray the prepared liquid strain on the larvae with a sprayer twice a day until it is wet. After 3 days, the larvae invaded by the bacterial liquid appear sluggish and coma, which can be cultured.
condition of culture
1, strains: Cordyceps cultivation must first have excellent pure strains, one is early maturity and high yield, the main purpose is to shorten the production cycle and reduce costs; To be infectious, it is required that the strain has strong vitality, the survival rate is above 95%, and it can quickly infect insects and get sick and die as soon as possible; It has a wide range of applications, especially against environmental temperature changes and other bacterial infections.
2. Insects: Batmoth larvae are mainly used as parasites of Cordyceps sinensis. Larvae must be alive, large and obese, and the number depends on their own breeding. Generally, larvae 1 kg, parents 1 individual and 50 kg of fine sand are required per square meter.
3. Environment: Artificial cultivation of Cordyceps sinensis can not consider altitude, but depends on temperature. Cordyceps sinensis is a medium-low temperature fungus. The temperature of mycelium growth and propagation is 5-32℃, the optimum temperature is 12- 18℃, and the optimum temperature for sclerotia and matrix formation is 10-25℃.
4. Cultivation season: Natural temperature can be used to cultivate two seasons a year, namely March-May in spring and September-165438+10 in autumn. If the indoor temperature is controlled, it can be cultivated all year round and the growing period can be shortened.
