シイタケ菌床栽培条件の最適化研究

抄録

There are two methods of shiitake mushroom cultivation: log cultivatioll and bed cultivation. Which method is employed depends on the use of the mushrooms,the climate, and the cultivation environment, In this experiment with bed cultivation, shiitake mushrooms were cultivated in a greenhouse with minimal air conditioning, in consideration of overseas (e.g., Chinese) cultivation methods and conditions, and the results were evaluated to find optimum conditions. When bed cultivation is practiced in the forests of China, for example,lack of funds and equipment makes it difficult to control temperature and humidity, employ stimulated growth methods, or take contamination counter-measures. A one-year experiment was performed under equivalent conditions to find optimal management methods and technologies. As a result, it was determined that the cultivation conditions should be changed in the summer and the winter, and that important improvements were needed in the areas of contamination of the bed substrate, harvest of mushrooms of even size, temperature and humidity control in the winter, and dealing with small mushrooms that sprout in the bag if the substrate is immature. In a confirmation experiment,problems remained in gain reproducibility, especially in winter cultivation, partly because of the effects of contamination, temperature and humidity control, etc. in the greenhouse.
