1. The Management in early autumn: The primary characteristics of August and September weather is the temperature ranging from 20-30 degrees Celsius, making it particularly suitable for the growth of Shiitake at the higher temperature range. Early autumn bring about less rainfall and high relative air humidity. Due to such weather condition, it is best to raise relative air humidity, by implementing moisture-retaining tactics, spraying water every morning, noon, night and providing ventilation for 1 hour every day to promote the growth of sporocarp. Throughout summer, the water content of mushroom bag is prone to depletion, which is why you should increase the difference, humidity differences to stimulate the budding soon. The conditions are optimized start forming within 3 or 4 days.
2. The Management in autumn and winter:
A. Management guidelines: Mushrooms grown in the period from September to November fall under those with autumn characteristics. In September, the temperature gradually decreases so when you find buds, then adopt cultivation techniques in accordance with weather conditions to cultivate thick mushrooms and flower mushrooms. With the onset of autumn rains and the rise in relative air humidity, you could firstly cultivate thick mushrooms. In sunny day too, provide ample opportunities to cultivate flower mushroom. When buds grown to a height of 2-3cm, conduct catalyzing management. The specific method is to adopt the sun-shade method to control the temperature and keep it in a range of 18-20 degrees Celsius. In mountainous areas, adopt a single layer of sun-shade net, adjust light intensity and lower the temperature. After picking the first flush of mushroom, clean the mushroom feet and conduct the cultivation of mushroom again in a temperature range of 20-25 degrees Celsius for one week until the part of stipe becomes white, after which you could start with catalyzing the second flush of mushrooms. The period from December to the next February is the optimal management period for winter mushrooms and is the best time to cultivate flower mushrooms, when you can also cultivate two-flushes of flower mushrooms. For that purpose, remove the sunshade and provide direct sun exposure to mushroom layers and mushroom sacks, adjusting greenhouse temperature to a range of in 8-16 degrees Celsius. You should be careful to increase the temperature when it falls below 8 degrees Celsius. In the daytime, open the thin film and let tiny mushrooms grow under the warm sun.
B. Bud-stimulation: Throughout summer, make sure to regularly provide adequate moisturize. The following conditions should be met in bud-stimulating: the optimal temperature is to be maintained at a range of 10-20 degree Celsius, the viable temperature difference is 8-10 degree Celsius. The water content of the mushroom bag should be adjusted in about 55% and the relative air humidity should be maintained in 85%-90%.
C. Flower forcing: Keep the temperature during daytime in a range of 15-20 degrees Celsius, and midnight, raise the temperature and increase humidity to create temperature conditions in a range of 15-20 degrees Celsius, and the humidity in a range of 85%-90% in mushroom bag. After 2 to 3 hours when the mushroom surfaces become wet and the lamella absorbs water, you should uncover film and conduct flow forcing. upon observing cracks are white and deep, you should quickly exhaust moisture, reduce the humidity to 65% and finally maintain at about 65%. Finally, through exhausting moisture, white cracks could be settled.
