1, raw materials.
Raw material preparation is very important for artificial cultivation of Cordyceps sinensis. When selecting mycelium, we should choose high-yield and high-quality strains with strong adaptability, fast grass emergence and stable characters. The main material for cultivating Cordyceps sinensis should be rice or corn without mildew and pollution.
2. Prepare the culture medium.
The preparation of culture medium is very important for the cultivation of Cordyceps sinensis. When preparing the culture medium, it is necessary to prepare 1 kg of rice, 35g of Cordyceps antifogging agent and1.5kg of clear water. When they are ready, they put 50 grams of rice per bag or 100 grams into plastic bags, pour 1.5 liters of 50-degree hot water into a clean basin, then put the special antifouling agent for Cordyceps into the hot water, dilute the nutrient solution into the plastic bags filled with rice in proportion, and then tie the plastic bags tightly.
3. Inoculation and culture.
Closing the door to prevent other miscellaneous bacteria from entering the inoculation with the air is the most important step. Operators' hands should be disinfected with 75% alcohol. Cordyceps sinensis belongs to low-temperature fungi. The growth temperature of mycelium is between 5 and 30 degrees, but the external temperature is 15 to 25 degrees, and the mycelium grows fastest, and the indoor humidity should be kept at 80% during culture.
Step 4 harvest.
Artificially planted Cordyceps sinensis can be harvested when its base is orange-red or orange-yellow, and its rod-like shape no longer grows. Then you can collect it from the base with a knife or scissors, put it in a clean container, dry it or dry it in the sun, and then put it directly into a sealable plastic bag for storage or sale.
Characteristics of Cordyceps sinensis.
Cordyceps sinensis is composed of insect body and fungal stroma growing from the head. The worm is like a silkworm, with a body length of 3-5cm, a diameter of 3-8 mm, a dark brown to yellowish brown surface with 20-30 ring lines, and the ring lines near the head are thinner. The head is reddish brown, with 8 pairs of feet and 4 pairs in the middle. Fragile, easily broken, slightly flat section, yellow and white. Daughter seat is solitary, slender and round, 4-7 cm long and about 3 mm in diameter; The face is dark brown to brown, with fine longitudinal wrinkles, the upper part is slightly enlarged, and there is no obvious difference between the head and the handle; The material is flexible and the cross section is white. The smell is slightly fishy and light.
