摘要
研究金针菇(Flammulina filiformis)发菌室内菌丝培养期温度(15、16、17℃,分别记为低温LT、中温MT、高温HT)和时间(20～27 d)对产量的影响,结果表明:在菌丝培养过程中,随着培养时间延长,栽培瓶内培养料温度逐渐升高,栽培瓶内外温差最高可达4 ℃,HT的瓶内平均料温高于LT 3.16℃.菌丝培养22～27 d后出菇,MT菌丝培养22 d的产量最高(每瓶472.13 g).以MT每天培养温度总和为基准,分别通过延长和缩短LT和HT的培养时间,使三者温度总和相同,比较出菇产量,发现LT(23 d,每瓶465.69 g)和HT(20 d,每瓶393.94 g)平均产量均低于MT(22 d,每瓶472.13 g).发菌室1～6 d为16 ℃、7～22 d为14 ℃的条件可以提高产量.
Abstract
The effect of different cultivation temperatures,LT(15 ℃ for the first 6 d and then 13 ℃ for the rest time),MT(16 ℃ for the first 6 d and then 14 ℃ for the rest time)and HT(17 ℃ for the first 6 d and then 15 ℃ for the rest time),and cultivation time(20-27 d)on Flammulina filiformis yield was studied.The results showed that the temperature of culture substrate inside culture bottles gradually increased as the mycelium cultivation time extended,and the maximum temperature difference between the inside and outside of culture bottles reached 4 ℃.The average substrate temperature of HT was 3.16 ℃ higher than that of LT.Fruiting bodies started to emerge after mycelium cultivation for 22-27 d,and the yield of MT with mycelium cultivation for 22 d was the highest,reaching 472.13 g per bottle(1 200 mL).Based on the accumulated daily culture temperature of MT,the cultivation time of LT an HT was prolonged and shortened respectively to keep their accumulated daily temperature consistent with that of MT,and the yields of LT(23 d,465.69 g per bottle)and HT(20 d,393.94 g per bottle)were lower than that of MT(22 d,472.13 g per bottle).In summary,cultivation under 16 ℃ during day 1 to day 6 and then 14 ℃ from day 7 to day 22 improved the yield of F.filiformis.
