Pleurotus eryngii mycelium bag full of mushroom management, single head mushroom bag can be upright discharge on the bed frame, double head mushroom bag can be horizontal code on the bed frame, the technical points are as follows:
1. Open the bag when the mycelium has not kinked before opening the bag, it is difficult to form the primordium or primordium to form very slowly, the mushroom is not neat, the economical character of the mushroom body is poor; when the primordium is formed or the bud mushroom buds are opened, the primordium differentiation and the small Mushrooms are well developed, fruiting and orderly, and economical characters of the mushroom body are good; if the fruiting body is opened when the fruit body has grown, malformed mushrooms will appear in the bag, and the mushroom that grows out will shrink and rot when it grows seriously. Therefore, the bag-opening time of bag-shaped Pleurotus eryngii should be controlled by opening the bag when the mycelium is kinked to form the primordium and the bud has emerged. Unwrapping the bag opening will make the bag film roll over to the upper surface of 2cm. .
2. The temperature of mushroom house directly affects the formation of primordia and the growth and development of fruit bodies.
When the temperature is lower than 8 °C, the original base is difficult to form, that is, the already long mushroom body will stop growing, shrinking, turning yellow until death;
When the temperature is above 18°C, the differentiated fruit bodies will suddenly grow rapidly and their quality will decline.
When the temperature is above 20°C, the mycelium turns to vegetative growth, the effect of low temperature stimulation also disappears, the primordium ceases to develop, the nutrients in the buds turn back and wilt, and the formed young mushroom will also shrink and die. Therefore, the mushroom house temperature should be controlled at 13-15°C during the mushrooming period, so that the mushroom is fast, the mushroom bud is more, and the mushroom is neat, and it can be harvested in about 15 days.
3. Humidity mushroom room air humidity should be maintained at 85% -95%, humidity is too low, fruiting body
Will shrink, the original base crack can not be differentiated, in order to improve the air humidity, it is best to use the sprayer nozzle spray water upward, do not spray water on the mushroom body, or fruiting body will affect the quality of yellow, in serious cases will cause decay.
4. Ventilation now requires sufficient oxygen for the original base period, and the CO2 concentration should be reduced to about 0.5%. Otherwise, the primordium will not differentiate and expand into a spherical shape. During the growth and development period of the mushroom body, fresh air is also needed, and the CO2 concentration should not exceed 0.4%.
During the fruiting period, if the ventilation is poor, due to the high CO2 concentration, malformation mushrooms will appear, and if it encounters high temperature and high humidity weather, it will also cause fruiting bodies to rot. Therefore, the mushrooming room must maintain good ventilation and ventilation conditions, especially when a large number of mushroom buds occur, straightening the bag mouth membrane in time to prevent malformation due to lack of oxygen.
5. Illumination of the original primordial and fruiting bodies requires a certain degree of scattered light, and the appropriate light intensity is 300-500Lx. Note that there should be suitable light for each floor or row of bed frames, and there should be no dead ends.
