In the northern region, can cordyceps sinensis be grown?

1.Real Cordyceps sinensis cannot be cultivated artificially.

2.Because Cordyceps sinensis is a combination of insects and fungi.

3.The insect is the larva of the Cordyceps bat moth, and the fungus is the fungus of Cordyceps, and in the middle of summer, the snow and ice melt on the snow-capped mountain meadows above 3,800 meters above sea level, and the small bat moth leaves thousands of eggs on the flowers and leaves.

4.Then the moth eggs become small insects, burrow into the moist and loose soil, absorb the nutrients of the plant rhizomes, and gradually raise the body to be white and fat.

5.At this time, the spherical ascospores encounter the fungus bat moth larvae, and burrow into the body of the insect to attract nutrients and germinate hyphae.

6.Cordyceps bat moth larvae also become Cordyceps when they feed on leaves with Cordyceps fungus.

7.Fugal-infected larvae gradually wriggle to a distance of two to three centimeters from the surface, where they die on their heads and tails.

8.This is the "winter worm".

9.Although the larvae die, the fungus grows day by day until it fills the entire body.

10.In the late spring and early summer of the following year, a small purple-red grass grows on the head of the insect, about 2 to 5 centimeters high, with a pineapple-shaped sac shell at the top, which is called "summer grass".

11.Cordyceps is the most fully developed in winter and spring, and the active ingredients in the body are the highest, which is the best season for collection.

12.Qinghai, Diqing and Nujiang Prefectures in Yunnan Province are one of the main producing areas of Cordyceps sinensis in China.

Cordyceps sinensis planting conditions include cultivation time, temperature control, light requirements, etc.

1. Cultivation time.

If it is to use the natural temperature to propagate Cordyceps, it is best to plant it in March to May in spring or September to November in autumn every year, if it is propagated in a greenhouse, it can be cultivated all year round, and it can also shorten the growth period and reduce labor costs.

2. Temperature control.

During the growth process of Cordyceps, the requirements for temperature are higher, and its mycelium grows well in the environment of 12-18 degrees, although the growth of low temperature is slow, but there are fewer miscellaneous bacteria, and the survival rate is higher.

3. Lighting requirements.

Cordyceps sinensis does not need sufficient sunlight in the process of cultivation, and it is advisable to scatter light during the development period of the sub-seat, avoiding direct sunlight, and can build an artificial shade for it in summer, or place it in the shade for maintenance.

The growth habit of Cordyceps

Beginning in late August every year, the larvae of the host bat moth of Cordyceps sinensis encounter ascospores of Cordyceps sinensis spread by wind or rain, and are infected when the environmental conditions are suitable, and the infected larvae are sluggish, and crawl to the surface near the surface at 2 9 o'clock in October to die as zombies. Cordyceps sinensis absorbs nutrients from insects for growth and reproduction, resulting in hyphae in the insects, and then forming a subplot. From November to February, the ground temperature is very low, and the growth of the subplot is very slow or even stops.

In May, the temperature rises to 4 10, the soil thaws, the body surface of the zombie worm grows hyphae and binds to the soil into a membrane skin, and the fruiting body rapidly grows upwards to 20 50 mm rod-shaped fruiting body, exposing the ground; From June to mid-July, the head of the fruiting body gradually expanded, and the ascospores matured and ejected under suitable temperature, humidity and light.

At this time, the underground zombie worms decay, the fruiting body is hollow, and the spores that spread out are infected with bat moth larvae with the help of wind and water. In its natural state, it takes about 3 years for Cordyceps sinensis to complete the asexual and sexual generations.
