| 摘 要： | 研究沙性土壤中不同泥炭添加量（0、10、20、30、40和50g／kg）对草地早熟禾（Poa pratensis）地上及地下根系生长的影响。结果表明，随着泥炭含量的增加，草坪质量、草坪密度、地上生物量、根系生物量、根冠比均呈现先增加后降低趋势，最大值因指标和月份的不同分别出现在20～30g／kg。不同泥炭含量之间，草坪...

| Abstract: | The effect of different peat contents(0 g,10 g,20 g,30 g,40 g and 50 g per kg) in sand-based soil on growth of Kentucky bluegrass(Poa pratensis).The main results indicated that turf quality,turf density,aboveground biomass,root biomass and R/T increased with peat content and the peack values appeared while the peat content was ranged from 20 to 30 g/kg,and after that they declined.Based on the percent of root amount in different depths,it showed a trend of that the root amount in upper layer was increased a... |
