Abstract:
Polyacrylamide-typesuper absorbent polymers (SAP) was used in Pleurotus ostreatus cultivation.The effects of different dosage (2‰,3‰,5‰) of SAP on the mycelial growth rate,fruiting body yield and quality of P.ostreatus were studied.The results showed yield and biological efficiency of were maximized in 2‰ SAP dosage,that indicated SAP played an active role in water-saving and yield-increasing.Additionally,the safety of SAP in P.ostreatus cultivation was evaluated.The SAP kept polymerstructure and had high thermal stability in high temperature and high pressurecondition.Further,acrylamide (monomer of polyacrylamide) was not detected in P.ostreatus fruiting body that cultivated with SAP.
