Recently, scientific and technical staffs from Beijing Agricultural Technology Extending Stations went to the leisure picking demonstration base of mushroom in Fangshan District for field study on the growth conditions of Ganoderma, Grifola frondosa and other mushrooms. Currently, bag-cultivation Ganodermas have become mature and entered into picking season. The fruiting condition of the third flushes on Grifola frondosa is desirable. Pleurotus citrinopileatus, Shiitake and other varieties are continuously fruiting and it is estimated that the fruiting time will terminate soon.
