Cordyceps can be artificially cultivated. 1, medium preparation: prepare steamed wheat grain, crushed corn, rice, etc., and put them into canning jars, and then use plastic film to seal the lid, and reinforce the sealing with rubber bands, and then carry out autoclave sterilization. 2, strain transplantation and cultivation: use flame-sterilized inoculating rings to transplant the cordyceps strain into the medium, and then transfer the canning jars to 10-28℃ for mycelium cultivation. -28 ℃ environment for mycelium culture, until the bottom of the medium white and a lot of aerial mycelium to the sealing film, while the color from snow white to gray to brown-yellow, can be cultivated.
First, Cordyceps can be planted artificially
Cordyceps can be cultivated artificially, cultivation techniques are as follows:
1, medium preparation
(1) prepare steamed wheat, broken corn, rice, etc., and then loaded into canning jars (filling height of the height of the bottle of two-thirds), using the plastic film to seal the lid and reinforce the seal with a rubber band.
(2) high temperature sterilization. After the end of sterilization, wait until the temperature drops below 30 ℃, transplantation of strains, culture.
2, strain transplantation and culture
(1) Use the flame-sterilized inoculation ring to transplant the Cordyceps species to the culture medium. In the process of transplantation, the mouth of the bottle should not leave the flame above.
(2) Wait until the end of the transplantation of the strain, the canning jar will be transferred to the environment of 10-28 ℃ for mycelium cultivation (15-20 ℃ constant temperature conditions are most suitable).
(3) When the bottom of the medium is white and there are a lot of aerial mycelium growing to the sealing film, and the color changes from snow white to gray to brown-yellow, it can be used as a production species for artificial cultivation.
3, field cultivation
(1) choose loose, good air permeability, no waterlogged sandy loam for cultivation.
(2) open ditch for compartments, compartment width of 1m or so, the length is not limited, and then rake the soil 10cm deep, per square meter put 10kg of bran and wood chips mixture (bran: wood chips = 1:2), and soil mixed evenly and then paved.
(3) the cultivation of good strains of bacteria into the sprinkle (1 bottle per square meter), and then pat flat, covered with plastic film, and set up a shade with grass curtains.
(4) Every 7-10 days ventilation, the duration of each ventilation is 1-2 hours.
(5) When the white fungus covered the entire compartment, the color becomes grayish white or brownish yellow, and the substrate grows, the plastic film will be raised to arch the shed. When the sky is clear, spray water 1-2 times a day
(6) When the fruiting body grows to brownish-yellow or brownish-black color, harvest it.
Second, Cordyceps what place to produce the best
1, origin
Cordyceps is mainly distributed in China's Tibet, Qinghai, Gansu, Sichuan, Guizhou, Yunnan and other provinces of the high alpine zone and the snowy grassland area (elevation of 3,000-5,500m), which is at an altitude of more than 4,500m Cordyceps production areas for high-quality production areas, especially in Tibet Naqu and Qinghai Yushu output of Cordyceps is the highest quality.
2, identification methods
(1) Cordyceps body length of about 4-6cm, body width of about 0.4-0.7cm (in this range, the longer the thicker the quality of Cordyceps is better).
(2) The color of Cordyceps is usually dark yellow or brownish yellow, and if it is kept for too long, it will be light black.
(3) Cordyceps has 8 pairs of legs on its abdomen, and the closer to the center of the body, the more obvious the legs.
(4) The digestive glands of Cordyceps can be seen in the cross section, which is in the shape of a black V.
(5) The digestive glands of Cordyceps can be seen in the cross section.
(5) The bigger and swollen the head of Cordyceps, the better the quality of Cordyceps.
