Poplar mushroom, rich in amino acids and vitamins, attractive mushroom flavor, rich aroma, crisp and smooth, delicious. It is more popular in Europe and Southeast Asia, and the domestic price per kilogram of dried products is 160-180 yuan, which is a new variety of edible fungi with great development potential. Assassin is a medium temperature type fungus, the suitable growth temperature of mycelium is 25-27°C, the fruit body is 18-22°C, the spring cultivation is generally 2-3 months, and the 3-4 months are fruiting. Autumn planting for August-September bag, September-October mushrooming. Localities can arrange production according to local conditions. First, the cultivation of culture medium preparation formula: 1 bagasse 38%, cottonseed husk 36%, bran 20%, soybean powder 2%, lime powder 0.5%, sucrose 0.5%, calcium carbonate 2.5%, compound fertilizer 0.5%. 2 sawdust 80%, bran 15%, lime powder 1%, brown sugar 1%, gypsum powder 3%. 3 cottonseed hull 80%, rice bran 15%, soybean powder 2%, lime powder 0.5%, sucrose 1%, gypsum powder 1%, compound fertilizer 0.5%. Second, the cultivation measures 1, bag inoculation using 15 cm 35 cm 0.005 cm polyethylene or polypropylene plastic bag regular loading, the day of sterilization, high pressure for 2 hours or atmospheric pressure 100 °C constant temperature to maintain 5-8 hours, hot Pan, inoculation box (room) cooled to 25-28 °C temperature inoculation, in order to facilitate the germination of mycelium colonization as soon as possible. Inoculate with 75% alcohol on the surface of the culture medium immediately before inoculation and wipe it again. Selecting a clear midnight or early morning vaccination will help improve the survival rate of the inoculation of the bacteria bag. In the front of the bag, hit 2-3 inoculation points equidistantly, hit the hole, inoculate, while sealing with tape. 2. Management of germs and mushrooming Inoculation will be promptly moved into indoor stacking or in-line culture after inoculation, taking care to prevent high temperature damage. 3 days for the germination period, indoor temperature should be controlled at about 27 °C; 4-5 days for the growth period, room temperature at 25 °C is appropriate; 15-20 days for the vigorous period, should sparse bag heat, after 25-35 days culture The basic mycelium full bag. Unfasten the bag mouth and use a small spoon to remove the old bacteria on the surface. Fill the bag with water and leave it for a day and night to remove excess moisture. Vertical discharge indoor floor or bed frame, cover the newspaper, keep room temperature 18-22 °C, humidity 80% -95%, light intensity 300-500 lux, increase ventilation. After 5-10 days of bacteria bags can form mushroom buds. When the fruiting body grows up to 2-3 centimeters in time, straighten out and untie the plastic bag or bagging to increase the carbon dioxide concentration, promote the growth of the stipe, and inhibit the development of the cap, and increase the yield and quality. After the original primordium is formed, it can be harvested 5-7 days later. 3, harvest and post-management management Cap diameter 2-3 cm, the edge of the color began to fade when harvesting appropriate harvest period. When harvesting, it is necessary to gently grasp the base of the mushroom stem to twist it and pull it off to prevent the handle from breaking off and pick it off and lay it flat in the mushroom basket. After the completion of the first tidal mushroom, reduce the amount of water spray to restore the growth of mycelium. If there is not yet a second tide after 10 days, use a sterilized hand to remove a thin layer of bacteria to stimulate mycelial growth, and within 2 days Can't spray water. After the second tidal mushroom is harvested, a small amount of potassium dihydrogen phosphate and glucose nutrient solution may be sprayed.
