Shiitake Mushroom Cultivation Technology（1）

Spring is the peak fruiting period for shiitake mushrooms. Generally, 4 to 5 batches of mushrooms can be produced, with an interval of 10 to 15 days between each crop. The following points should be paid attention to in the management of mushroom fruiting period in spring:

1. Replenish moisture: After mushrooms have produced in autumn and winter, the internal nutrients and water content have been significantly reduced, with some weight reduced by 1/2 and water content reduced by 30%. In order to quickly restore the growth of mycelium, the moisture and nutrients in the mushroom rods should be replenished and the relative humidity of the air should be reduced to obtain high spring mushroom yields. At the same time, by replenishing water, the dry-wet difference on the surface of the mushroom rods is artificially widened, which can stimulate the formation of mushroom buds.

2. Strengthen ventilation: After the bacteria stick is soaked in water, it is during the period of heat preservation and bacteria growth. Ventilation is required 1 to 2 times a day for 1 to 2 hours each time. On rainy days, the ventilation time can be extended to increase the oxygen concentration in the mushroom house and reduce the carbon dioxide concentration.

3. Widen the temperature difference: After soaking the mushroom sticks in water for 3 days, remove the covering film to widen the temperature difference in the mushroom bed. It will enter the reproductive growth stage from the vegetative growth stage again, inducing the mushroom rods to form more mushroom buds, thus making the mushroom tide obvious and the mushroom buds uniform.
