The white mushroom is a specialty of Changbai Mountain. It is clustered in a circle. Therefore, it is delicious and has a high nutritional value. It can produce 500 kilograms of dried mushrooms per acre. Cultivation season: Spring is planted from late March to early April, and mushrooms can be harvested in May. In late autumn, it is planted from late July to late August. In September, mushrooms can be harvested, and 3-4 crops can be harvested continuously. Cultivation materials: 1. Weeds (arrows, grass) or straw 70%, wheat bran 15%, bean powder 3%, corn flour 10%, brown sugar 1%, gypsum 1%, micronutrients. 2. Corn kernel 75%, wheat bran 17%, bean powder 3%, corn flour 3%, brown sugar 1%, gypsum 1%, micronutrients. 3, corn cob 50%, straw (or weeds) 25%, wheat bran 15%, corn flour 5%, soy flour 3%, brown sugar 1%, gypsum 1%, micronutrients. The above-mentioned culture materials should be fresh and all moldy and deteriorating materials should not be used. After the corn cob is dried, it will be crushed into beans. The weeds or rice straw should be crushed into filaments and fully air dried for two or three days before use. The finer the comminuted corn flour and soy flour, the same as flour. Cultivation bag production: 1, preparations: choose a good mixing site, it is best cement floor, there is no condition can also be used in the plastic film on the ground. 1733 cm polypropylene corner bag for plastic bags. Zhakong with sticks. 2. Mixing and bagging: Hold the bottom four corners of the bag into a cylinder, compact it with edges, and do not fold. Pack 17-18 cm high, flatten the material surface, and use a wooden stick to clockwise Hole in the end, but can not puncture the bottom of the bag, then pull out the stick in a clockwise direction, and then set the collar, plug the tampon. The tampon is 5-6 cm away from the material to facilitate ventilation. 3, atmospheric pressure sterilization: according to the scale of production can be large or small, with red brick cement or wooden, iron can be made. During the sterilization process, the fire quickly burns, and the timing starts at 100°C as soon as possible, and lasts for 6 hours. After the ceasefire, the pot is boring for 1-2 hours, and the excess fire is removed, and then the lid 1/3 is released. Wait until the temperature drops to about 40°C. Inoculation, cultivating; wet vaccinations when the culture bag temperature drops below 30°C. Inoculation can be used with a comprehensive inoculation method, according to the routine inoculation, 25 bags per strain of bacteria can be connected. After inoculation, the bacterium is cultured. The bacterium culture room must first be sterilized and sterilized. The shelf or code rack on the cultivation bag can be maintained. The indoor temperature is maintained at 25° C., and the relative humidity of the air is 55%-65%. After 1/3 of the mycelial material is eaten, it should be promptly ventilated. After about 40 days, the mycelium can fill the whole bag. Cultivation methods: On the plastic shed ground for 1 meter wide, 10 to 15 centimeters deep, 5 to 6 centimeters in length, with 50 to 60 centimeters for each ridge. In the oyster first drenched water, until the water infiltration after spraying 1:800 times clomazone sterilization sterilization, and then spray 1:500 times the enemy to kill or drip fear exterminator, and then will be covered with hyphae cultivation bag Go to a plastic bag and place it in Chinese herbal medicine. The bag is 10 centimeters long and 10cm apart. 25 bags per square meter can be placed. The middle of the bag is covered with soil, the water is kept wet, the top of the bag is not covered with soil, and the exposed light is seen outside. Light stimulates the formation of primordia for mushrooming. Mushroom management: After the cultivation bag is put into the pot, the relative humidity in the plastic shed must be increased to reach 80%-85%. If the humidity is insufficient, the water can be sprayed. After the fruit body is formed, the humidity is gradually increased to 95%, and the temperature is kept 15-25. °C, always pay attention to ventilation, see scattered light, avoid direct sunlight in order to avoid aging affect production. After the first harvest, dry 5-7, restore mycelial growth, and then inject nutrient solution, top cover fine soil 2 cm, spray large water once, maintain air relative humidity 80% - 85%. The other management is the same as the first oyster mushroom, properly managed, can receive 3-4 mushroom. Harvesting and processing: The mushroom cover is unrolled slightly downwards and has not yet fired spores. It can be harvested after eight minutes of ripening. The entire flower can be cut with a knife without destroying the original base. After harvesting, the small flowers can be dried separately, gradually emitting a fragrance, avoiding sun drying to prevent loss of aroma. Dried mushrooms are packaged in cartons or special gift bags for sale.
