Temperature-difference bud-induction technique for shiitake mushrooms grown on layered shelves without removing the bags
The fruiting stage of summer mushrooms falls in the hotter season, which is unfavorable for the growth and development of the fruiting bodies. Poor management easily leads to shriveled buds and rotten mushrooms. How can cultivation protection facilities be used and corresponding measures taken to curb the effects of the adverse environment? This is the most important part of fruiting management in summer cultivation. According to the experience of the main producing areas, the main measures are as follows...
Shiitake mushroom logs must be stimulated by a temperature difference to form fruiting body primordia. The size of the required temperature difference and the duration of the temperature difference vary with the strain. After the logs are placed on the shelves, logs that have reached physiological maturity are moved onto the shelves, are in a dispersed state, and receive the stronger diurnal temperature difference stimulation and light stimulation inside the mushroom shed. The mature mycelium begins to knot and form fruiting body primordia, and then mushroom buds appear. Temperature-difference bud induction means artificially increasing the temperature difference under natural shade shed conditions, that is, covering with plastic film during the day when the temperature is higher to raise the temperature of the logs, and uncovering the plastic film at night so that cold air directly strikes the logs, promoting the occurrence of mushroom buds.
