Chaga mushroom cultivation points
Agrocybe aegerita, also known as Agrocybe, is a rare edible mushroom. It has a crisp and tender handle, a pure fragrance, and an excellent taste. It can be cooked into a variety of delicacies. Approved by the China Food Quality Supervision and Inspection Center, the fruit body contains important nutrients such as dextran, protein, and minerals. It is rich in 8 kinds of amino acids needed by the human body, and its lysine content is as high as 1.75%. Strong kidney-building efficacy and anti-tumor activity is one of the top ten best-selling bacteria products in the international mushroom trading market. China's Agrocybe aegerita mainly depends on natural collection. Until now, artificial cultivation has only begun. However, the scale of cultivation is small, and the products are far from meeting the market demand. The current purchase price in China is 160-200 yuan per kilogram dry product. Therefore, artificial cultivation of Agrocybe aegypti has significant economic benefits and a broad market prospect. In the cultivation season, the growth temperature of the mushroom mushroom mycelium is 10～35°C, and the optimum temperature is 22～27°C; the fruit body formation and growth temperature is 16～32°C, the optimum temperature is 20～28°C, and can be cultivated in spring and autumn. There are two principles to master: First, within 40 to 50 days after inoculation, the local temperature does not exceed 32°C. The second is to push forward 60 days from the inoculation date, the local temperature does not exceed 30°C, and not less than 15°C. Formula 1 for raw materials, wood chips 72%, wheat bran 25%, gypsum 1%, sugar 1%, superphosphate 0.5%, lime 0.5%. Formula 2, cotton shell 78%, wheat bran 20%, gypsum 1%, sugar 0.5%, lime 0.5%. Formula 3, wood chips 38%, wheat straw powder or corncob 37%, wheat bran 23%, gypsum 1%, superphosphate 0.5%, lime 0.5%. The bacterium bags were made of polypropylene bags with a size of 17 cm, 33 cm and 0.05 cm. The raw materials were mixed and mixed well, the moisture content of the material was 60% to 62%, and the pH value was 6 to 6.5. Fill the bag with 18 cm in height (about 450 g dry material per bag) and put on the collar and stuff the tampon. The autoclave was sterilized and kept at 100°C for 10 to 12 hours. After the end of the sterilization, it was cooled to below 30°C and inoculated in the inoculation or inoculation room. Each bottle of original species expands 25 to 30 bags, and then placed in a cool, dry, clean and well-ventilated culture room. The mycelial full bag usually takes 40 to 50 days. Mushroom management When the mycelium grows full of bags, it transfers from vegetative growth to reproductive growth. The material surface secretes yellow water and presents brown patches. When growing small buds, it must be opened in time, straightened in the mouth, and watered on the ground. Maintain the indoor air relative humidity of 85% to 90%, and give a certain amount of scattered light irradiation and ventilation. After 10 to 15 days of management, the child entity can be harvested when it matures. Harvesting from bud emergence to harvest usually takes 5 to 7 days. When the cap is hemispherical, the ring must be harvested before it has escaped the cap. After harvesting 2 tidal mushrooms, the material has been dried out, and each bag can be filled with about 40 ml of water. Generally can be harvested 3 to 4 times, each bag can receive dried mushrooms 40 to 45 grams. Processing scissors cut off the root debris, can be listed on the sale of fresh, dehydration dryer can also be used to dry, grading packaging. At present, China mainly exports dry goods to Southeast Asian countries such as Singapore, Japan and South Korea.
