1, cultivation time
If the natural temperature is used to breed Cordyceps sinensis, it is best to plant it in March-May in spring or September-11month in autumn every year. If it is propagated in greenhouse, it can be cultivated all year round, and it can also shorten the growth period and reduce the labor cost.
2. Temperature control
In the growth process of Cordyceps sinensis, the temperature requirement is high, and its mycelium grows well in the environment of 12- 18 degrees. Although it grows slowly at low temperature, there are fewer miscellaneous bacteria and the survival rate is higher.
3. Lighting requirements
In the process of cultivating Cordyceps sinensis, it is not necessary to have enough sunshine. It is advisable to scatter light during the development period of the pedestal to avoid direct sunlight. In summer, an artificial shade shed can be built for it, or it can be placed under the tree for maintenance.
Growth habit of Cordyceps sinensis
From the end of August every year, the host bat moth larvae of Cordyceps sinensis encounter the ascospores spread by wind or rain, which are infected when the environmental conditions are suitable, and the infected larvae move slowly, and climb to the near surface at 2-9℃ in1October and die as stiff worms. Cordyceps sinensis absorbs the nutrition of the worm to grow and reproduce, so that the worm is covered with hyphae and then forms a daughter seat. 1 1 month to February of the following year, the ground temperature is extremely low, and the daughter growth is very slow or even stops.
In May, when the temperature rises to 4- 10℃, the soil thaws, and mycelium grows on the surface of the stiff worm and bonds with the soil to form a film skin, and the fruiting body quickly grows up to a rod-shaped fruiting body of 20-50 mm, exposing the ground; In the middle and late June-July, the head of the fruiting body gradually expands, and the ascospores mature and eject under suitable temperature, humidity and light.
At this time, the underground dead worms rot, the fruiting body is hollow, and the diffused spores infect the bat moth larvae with the help of wind and water. In natural state, it takes about 3 years for Cordyceps sinensis to complete asexual and sexual generations.
