摘　　要：采用响应面法研究荞麦秸秆生物质育苗钵密度、跌落破损率和承压破损率3个物理性能与成型压力、粘结剂用量及保压时间的关系,并应用多目标粒子群优化(MOPSO)算法对工艺参数进行三响应优化分析。试验结果表明:当压力为8~12 MPa、粘结剂用量为60%~90%、保压时间为11~14 min时,育苗钵密度可达1.041 g/cm^(3)以上,跌落破损率和承压破损率分别在2.97%和2.65%以下。最优成型工艺参数为压力11.73 MPa,粘结剂用量60.5%,保压时间12.7 min,此条件下育苗钵密度达到1.168 g/cm^(3),跌落破损率和承压破损率分别为2.52%和2.58%。Response surface methodology(RSM)is used to study the relationship between three physical properties of biomass seedling pot density,drop breakage rate and pressure breakage rate of buckwheat straw and molding pressure,dosage of binder and holding time.MOPSO optimization algorithm is used to carry out three response optimization analysis of process parameters.The experimental results show that when the pressure is 8-12 MPa,the amount of binder is 60%-90%,and the pressure holding time is 11-14 min,the seedling pot density can reach above 1.041 g/cm^(3),and the drop damage rate and pressure damage rate are below 2.97%and 2.65%,respectively.When the optimal molding parameters are pressure 11.73 MPa,binder dosage 60.5%and holding time 12.7 min,the seedling pot density reaches 1.168 g/cm^(3),and the drop damage rate are 2.52%and 2.58%,respectively.
