Moderator: Hello everyone, here is the "Rural Micro Classroom", today we are very honored to invite Wang Hua, a teacher from the Institute of Edible Mushrooms of Shanxi Academy of Agricultural Sciences. Hello, Teacher Wang.
Teacher Wang: Hello host, hello everyone.
Moderator: Okay, in this episode of the program, we would like to ask Teacher Wang Hua to introduce the germ management of Bailing mushrooms.
Teacher Wang: The key technology of germ management is to maintain a dark light dry germ chamber, to keep the air fresh, the temperature is kept between 24 degrees and 26 degrees, there are about 40 days during the germination period to prevent high temperature, the middle period to prevent hypoxia, the later stage is to prevent infection, the whole process of anti-yellow water, the environment should be clean, and the hygiene must be done well. The first technical essential of the 1st to 15th day is temperature, the temperature should be maintained at 24 degrees to 26 degrees, the measurement should be 4 times a day are 8 o'clock, 2 o'clock, 8 o'clock at night and 2 o'clock at night, to strictly control the temperature, can not exceed 28 degrees, to 27 degrees when the cooling measures should be taken. Then there is humidity, relative humidity is maintained at 70%, the germ room should be kept dry and hygienic, because its demand for oxygen is relatively large, to keep the air fresh, to achieve regular ventilation. If the temperature is high during the day, ventilate in the evening or in the morning. Then there is the light, if it is a dark light germ, the door and window light transmission place to cover the curtain, shading without affecting the ventilation, 7 days ago the hyphae are in the process of germination and feeding, this time do not go to turn the fungus bag, to see the degree of air freshness in the germ chamber and the temperature of the high and low, humidity and other conditions, morning and evening or noon, to ventilate for half an hour to an hour or no ventilation, 7 to 10 days after the heap to check it, take it lightly, put the upper layer to the lower layer, and then flip the fungus bag for half a week, The purpose of looking over the pile of bacteria is to see if it has germinated hyphae, whether it is eaten and colonized, whether the growth is normal, whether there is a leaky strain or a bag with too much moisture content, whether there is any bacteria contaminated, and if there is a variety of bacteria, it should be quickly removed, and if it is missing or not germinated, it is urgent to replant. Then there is the water bag, in the case of normal germination, the water bag should be punched on one side, at this time, it should be placed on top of the white ash covered with 4 cm thick to drain the excess water. If there is a large area of infected bags, it should be quickly returned to the pot to deal with, if it is a small area, spray the disinfection king's liquid or how to deal with it, of course, it must also be combined with the weather conditions at that time. The technical essentials for days 15 to 40 are temperatures of 24 to 26 degrees.
Host: Or measure 4 times a day?
Teacher Wang: Yes, the humidity is still 70%, the air is also continuing to remain fresh, at this time the bag should be properly loosened rope or punched to increase oxygen, to promote the robustness and exuberance of this hyphae Rapid growth, the light should still keep the dark light at any time to observe. Also observe whether it has yellow water, and if it is to occur, quickly drain it. It should be noted that the pile is turned over every 7 to 10 days, and when it is 30 days to 35 days, it is 40 days for the hyphae to grow full. If its daily long speed is 0.3 cm is normal, at this time to properly prevent rodent and insect pests, timely turn over the pile to observe, this time is also relatively easy to attract pests, it is because it is full, the other is to timely prick hole oxygenation, prevention and control of hypoxia affects the growth of hyphae to observe hyphae, its growth edge puncture site to maintain 1 cm, puncture when not stabbing to the edge of growth, the depth should also be controlled within 2 cm, under normal circumstances is a bag to pierce 8 to 10 holes, 4 to 6 hours after the piercing the temperature has increased, so to keep the bag temperature at 24 degrees - 26 degrees, if you observe that the temperature of this room is 27 degrees, you must quickly reduce the temperature in time.
Moderator: Okay, at the end of the program, I would like to thank Mr. Wang Hua once again for being a guest of our program. Okay, that's the end of this episode, we'll see you next time.
