| 摘 要： | 以多年生黑麦草株高、根数、根长、根冠比为试验指标,优化粉煤灰的改良剂配方.运用均匀设计试验法,采用砾石、污泥、秸秆、磷矿渣作为原料配制改良粉煤灰种植黑麦草,考察了影响株高、根数、根长、根冠比的因素,对试验结果进行了二次多项式逐步回归分析和多目标综合寻优.结果表明:污泥对株高产生极显著的促进效应,对根数、根长产生极显著抑制效应,砾石对根冠比产生极显著抑制效应,砾石与秸秆互作对株高产生极显著抑制效应,砾石与磷矿渣互作对根数产生极显著促进效应,秸秆与磷矿渣互作对根长产生极显著促进效应,砾石与磷矿渣互作对根冠比产生极显著抑制效应,污泥与秸秆互作对根冠比产生极显著促进效应.优化结果:粉煤灰、砾石、污泥、秸秆、磷矿渣的用量分别是800.00g、360.00g、30.00g、32.84g、150.00g.

| Abstract: | In this study,raw fly ash was used with gravel,sludge,crop straw and phosphorus slag to develop modified fly ash matrix as artificial soil for L.perenne.After planting L.perenne.in it for 10 months,plant height,average root number,average root length,and root-shoot ratio were investigated to guide the optimization of the components of the matrix by using uniform design.Treated experimental data with the quadratic polynomial stepwise regression analysis and the multi-objective optimization method,results sho... |
