(一)选用大径栎木。日本宇都宫市郊的印出井,他的香菇生产规模每年为5000根菇木,品种90％为241号,其余为秋季上市的358号。现在由于生产规模扩大,种植菇木的劳力不足,只好购入原木。1米长的枹木为140日元,1米长的栎木为135日元。当地的生产者认为,栎木加工成段木困难,产菇量低。但印出井却选购栎木做原木,而且喜欢用粗径的。他认为,栎木能生产厚肉菇,产量也高。 (A) Selection of large-diameter oak. The printed wells on the outskirts of Utsunomiya in Japan have a production capacity of 5,000 mushrooms per year, with 90% of varieties numbered 241 and the rest 358 listed in the fall. Now due to the expansion of the scale of production, planting mushrooms lack of labor, had to buy logs. One meter long alder is 140 yen, one meter long oak is 135 yen. Local producers believe that the processing of oak wood into sections difficult, low production of mushrooms. However, the well is printed out to buy oak wood, but also like to use a large diameter. He believes that oak can produce thick mushrooms, the yield is high.
