Abstract:

For the aim of extensive utilization agricultural wastes resource to cultivating Pleurotus nebrodensis, cotton stalk, chestnut sawdust and peanut shell as the experimental material of 13 groups of formula, the cultivation test was carried out. Mycelium growth rate, yield and production cycle of different substrate formula was investigated and compared from inoculation data to harvest period. The results showed that the peanut shell, cotton stalk, chestnut sawdust may be applied for the cultivated substrate of P. nebrodensis and replaced part of cotton seed hull in cultivation medium. The highest yield formula was A4(contained 40% peanut shell), but the longest of the production cycle. After multiple analyzed, the optimum formula was C1(40% contton seed hull, 40% cotton stalk, 15% wheat bran, 2% corn flour, 2% lime, 1% gesso), the per-unit yield, biological efficiency and production cycle was 188.38 g, 53.81%, 150.7 d, respectively.
