At present, it is during the cultivation period of the mushroom. Some mushroom sheds vary in length, and the lower ones are thick and have dense small hairs. The mushroom covers are small. According to expert analysis, this is due to a period of high material temperature and inadequate nutrient supply.
Flammulina is a low-temperature-fed fungus that can grow in the range of 5°C~32°C, but the optimum temperature is 22°C~25°C; while the differentiation of fruiting bodies takes place in the range of 3°C~18°C, but The optimum temperature for forming is 8°C~12°C. Flammulina grew vigorously at low temperatures, and the above situation occurred when the temperature was high.
The use of flat cultivation method needle mushroom, bacteria bags placed on the ground level, the ground temperature is relatively constant, this material temperature is also relatively constant, why the material temperature is high? After investigation, the main reasons are as follows:
First, to mention the market in the morning, we need to put the bag into the mushrooming period prematurely. Mushrooms have a long germination time and a long age of bacteria. Many mushroom farmers provide the mushroom market for the morning market. After the fungus bag has germinated to about half, the bag is opened so that the upper golden mushroom body starts to form and grow, but the lower part of the mushroom bag continues to grow. Bacteria, mycelia grow downwards, and a large amount of heat is released during the germination process. As a result, the temperature in the bacterial bag rises and the mycelium grows too vigorously, while the growth of fruit bodies is insufficient.
It is recommended that the bag should be unwrapped to about two-thirds of the time when it is sterilized, and it is not appropriate to open the bag directly. You can untie the tying rope of the mushroom bag and breathe it. A few days later hand-pull the mushroom bag mouth outwards, so that the mushroom bag mouth becomes loose, and finally open the bag mouth is more appropriate.
Second, in order to maintain moisture, the improper management of the film makes the temperature too high. When growing golden needle mushroom, in order to moisturize, no matter it is the germination period or the fruiting period, it needs to be covered with a plastic film with a width of 1.5 meters before ventilating, and then be ventilated. Ventilation should be carried out at night. The arch shed is best Ventilate on both sides.
It is recommended that in the case of high material temperature, the film should be properly lifted to the bottom of the bag, so that the heat of the lower bag can be dispersed without drying the head.
