Title: The Cultivation of Shii-Take (Lentinus edodes) on Supplemented Sawdust
Author: P.P. Kalberer
In Europe, Shii-take growers face two important problems:
1) how to grow Shii-take with a good yield in a simple, inexpensive and dependable way and 2) how to increase demand for this mushroom which is still quite unknown in Europe.
Both problems need attention because production and demand should develop at about the same speed.
In my effort to further the cultivation of Shii-take, the fact that today’s demand for Shii-take in Europe is still quite low and that it probably will not rise very sharply in the near future has been taken into account. The emphasis is, therefore, on developing a cultivation technique which can easily be adapted to a growing market. It is my goal to develop a simple and dependable method of Shii-take cultivation suitable for small and medium-sized farms. The mushrooms are cultivated under controlled conditions in growing rooms on supplemented sawdust.
A number of people have published papers on Shii-take cultivation on supplemented sawdust (Ando 1976; Mori et al. 1976; Mee 1978; Han et al. 1981; Royse 1985 and Diehle and Royse 1986). These authors autoclaved the sawdust substrates before spawning.
My method is characterized by the following features:
1) The substrate is only heat-treated and not autoclaved. For small and medium-sized farms, the cost of large autoclaves is prohibitive. Dependency on autoclaving would also limit the production of substrate in larger farms. 2) All substrate ingredients must be readily available and cheap in Switzerland. 3) The harvesting period should be as short as possible because the cost of controlling the climate in the harvesting room with humidity control and light is rather high. The aim is to achieve as high a yield in as short a time as possible.
