The growth and development of the hyphae of lentinus edodes enters the physiological maturity stage. Under certain conditions, the white hyphae on the surface will gradually turn into a layer of brown mycelium, which is called hyphae color change. The depth of the color change and the thickness of the bacterial membrane directly affect the occurrence and development of the primordium of lentinus edodes. It has a great relationship with the yield and quality of lentinus edodes. It is the most important part of the management of mushroom fruiting. There are many methods of color conversion. According to different fruiting methods, it can be divided into the color conversion method without bag removal and the color conversion method without bag removal.
In the method of removing the bag and changing the color, it is necessary to accurately grasp the time of removing the bag, that is, when the hypha reaches physiological maturity, the bag is removed. Too early to take off the bag is not easy to change color, too late mycelium aging, often yellow water, easy to cause bacterial contamination, or thickening of the bacterial membrane, the differentiation of the primordium of the mushroom is difficult. The temperature when taking off the bag should be 15℃～25℃, and the maximum temperature is 20℃. Before removing the bag, first make the floor of the mushroom-growing greenhouse into a border of 30-40 cm deep and 100 cm wide, with a layer of furnace ash or sand on the bottom of the border, and transport the bag to be removed to the greenhouse with a blade Scratch the bacteria bag, take off the plastic bag, and arrange the columnar bacteria in the border at a distance of 5-8 cm. If the long column is not stable, use bamboo poles to build a horizontal frame on the border, and the column leaning on the bamboo pole at an angle of 70-80 degrees. After removing the bag, the bacterial column should be protected from the sun and wind. At this time, the relative humidity of the air in the greenhouse should be controlled at 75% to 80%. The bacterial column with yellow water can be rinsed with clean water. Take off the bag and arrange the column quickly, fill up the border, immediately arch the border with bamboo, cover with plastic film, press tightly around, moisturize and keep warm.
After all the bacterial columns have been drained, the temperature of the greenhouse should be controlled at 17°C to 20°C, not exceeding 25°C. If the temperature is high, spray cold water into the greenhouse space to cool down. During the daytime, add more shades to the greenhouse, remove shades at night, and strengthen ventilation to cool down. The light should be darker. Try not to uncover the film on the border for the first 3 to 5 days. At this time, the relative humidity in the border should be 85% to 90%. There are condensation water on the plastic film, so that the hyphae will stay in a warm and humid environment. Continue to grow in a stable environment.
It should be noted that during this period, if the temperature is high and the humidity is too high, it is still necessary to uncover the hood for 20 minutes in the morning and evening when the temperature is low. When uncovering the hood for ventilation, the greenhouse should not be ventilated at the same time, and the ventilation time of the two should be staggered. When standing up the column for 5 to 7 days, when the surface of the column is covered with thick white fluffy aerial hyphae, increase the number of uncovering and ventilation, 2 to 3 times a day, 20 to 30 minutes each time, increase oxygen, Light (scattered light) can increase the difference between dryness and wetness on the surface of the bacteria column, restrict the growth of mycelium and promote its color change. When the color starts to change in 7-8 days, increase the ventilation for 1 hour each time. Combined with ventilation, lightly spray water on the surface of the bacterial column 1 to 2 times a day, and let it dry for 1 hour before covering with the film. Spray water continuously for 2 days until the color changes in 10-12 days.
In addition to the color-changing method without taking off the bag, there is also the color changing without taking off the bag in production. Among them, some do not take off the bag, using acupuncture microporous ventilation to change the color method, and then take off the bag and produce mushrooms after the color is changed; some do not take off the bag, when the primordium of the mushroom fruit body appears around the inoculation hole of the bag, use a knife Cut the plastic bag around the primordium to expose the primordium for fruiting management. After the first mushroom is produced, the color of the whole bag is finished, and then the second mushroom is released from the bag. These color conversion methods are simple and good for moisture retention. Using these methods for color conversion in high temperature seasons can reduce contamination by bacteria.
