Amongst all the mushroom varieties, Shiitake holds the weakest growth trend. Under the unremitting endeavour of technical staffs working in Beijing Agricultural Technology Promotion Station, by now, production of liquid spawn on the majority of varieties such as Enoki, King oyster mushroom, Black fungus and Oyster has been realized, which is of great significance to stimulate the development of mushroom industry.

In order to do a great job on production of liquid spawn of Shiitake mushroom, by the research on selection of strain formula, technical links of strain cultivation and inoculation technology, preliminary result has been obtained by now. Liquid spawn shaken by magnetic stirrer carries robust mycelia and even balls. However, time for cultivation time is a little bit longer, and hence a further experimental study or investigation is needed so as to reduce the spawn-running period of strain.
