不同品系菌種對香菇與花菇段木生產之影響

Effects of Shiitake Spawn Lines on the Production of Dry Shiitake Shiang-Gu/Hua-Gu Log Wood Cultivation

本文以四種香菇菌種品系，即366號，367號，368號，及369號，每品系接種在3噸長尾尖錐木諸段木上生產花菇與香菇約二年。結果顯示以368號品系最適合生產花菇，即在1987年2月接種到1988年1～3月即可生產花菇約26公斤，培育二年至1989年二月約可生產35公斤花菇及65公斤香菇。栽培要點如下：1.選擇適當菌種品系：如368號冬天菇菌種。2.368號品系之特點為可生產菇體大而圓、屬白花毯色，且菇體重而多上級品之花菇及一般香菇。3.在陽光照射日接種。4.段木培養場所需（a）通風（b）有光線照射（c）有防雨設施（d）要排水良好。5.場內濕度宜保持在60%以內。段木培養期間如在2月間接種至翌年1～3月間（北部地區）為花菇主要產期，8～13°C為花菇生產之適合溫度。

Effects of 4 shiitake lines, i.e. #365, 367, 368 and 369 on the dry shiitake Shiang-gu and Hua-gu production by 3 tons of Chinkapin log wood for each line were compared. Results showed that #368 line could produce the highest amount of Hua-gu. The log woods were inoculated in February, 1987. Total for 2 years of log wood cultivation, 35 Kg of dry Hua-gu and 65 Kg of dry shiang-gu were produced by line #368. Total yield and grade of dry shiang-gu and Hua-gu are given for each line. Production conditions are recommended as follows for Hua-gu production in Taiwan: I. Select proper Shiitake line: #368 winter shiitake line. 2. The #368 Shiitake line could produce white and black color, big and round heavy weight fruiting bodies and good quality Hua-gu and normal Shiang-gu. 3. Inoculate spawns on chinkapin log wood on shining days of Febuary. 4. The location for shiitake cultivation should be in good ventilation, with sun light, good driange and rain-preventing facilities are also required. Humility not exceed 60% are essential. 5. The production of Hua-gu in Taiwan was mainly from January to March. Therefore, temperature ranged from 8-13°C are suitable for the production of Hua-gu.
