반지하온실을 이용한 추용(椎茸) 억제재배(抑制栽培) 시험 = Cortinellus edodes(Berk) Ido et Imai

다국어 초록 (Multilingual Abstract)

1) An experiment was made at the newly constructed glass house of Chun chan Agriculture callege to find out facts about the late-raising of Cortinellus edodes (Berk) Ido et Imai during the winter season.
2) The host timbers used in this experiment were Quercus Serrata Thumb and Quercus crispulo BI. ; 5 years old each, the diameter ranging from 6㎝ to 17㎝, dividing them into 12 diameter groups with 10 timbers in each group. The total number of timbess was 240 in two blocks.
3) As the pre-treatment of host timber, the autumn generation in 1962 was inhibited, and before being put into the glass-house, they were stimulated of generation for 3 days after 3 days, water-soaking.
4) The temperature control was made by using two coal stoves and the humidity control by spraying and two full water tanks. During cloudy weather and night, the green house was covered to preserue constant temperature of 5℃∼10℃.
5) The result ;
Qucreus Serrata Thumb. With lesser diameter than 9㎝ showed no generation either in as big timber as one with diameter 11㎝. On the other hand, too big timbers showed low rate of generation ; the reason, at a guess, is the too short period of cultivation and insufficient water soaking and inappropriate temperature.
6) The most standard size of host timber was found out be those with diameter 12㎝∼15㎝ in Quercus serrata Thumb, and those with diameter 14㎝∼17㎝ in Quercus crispula BI. Quercus criopula seemed to have slightly greater efficiency of generation than Quercus Serrata Thumb., but it could not be concluded as “decisive”. Lastly, the host timber used in this experiment were old and the rate of generation was low as a whole.
