Effect of Cultivation Temperature and Time on Flammulina filiformis Yield in Factory Production
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.
