摘要
采集武汉市中心城区主要公园绿地、道路绿化带、住宅区绿地和单位附属绿地土壤,研究其pH值、有机质、有效养分含量等理化性质,以摸清园林绿地土壤的基本性状。结果表明,土壤pH值较自然土壤明显偏高,以偏碱性为主;土壤有机质、速效磷和速效钾处于较高水平;碱解氮偏低;土壤主要是壤质土壤和粘质土壤;阳离子交换量较高。根据结果评价了武汉城市园林绿地土壤肥力状况,可为园林植物适地种植和科学合理配置与管理提供科学依据,推动城市绿化事业的发展。
Soil samples of park green space,road greenbelt,resident area were collected at central district in Wuhan City.Their pH,organic matter,available nutrients and CEC were tested.The results indicated that the pH values of soils from urban green space in Wuhan City were distinctly high compared with natural soils.Soil organic matter,available P and available K were high,whereas soil alkali-hydrolysable N was low.The soil texture was loam and clay,and soil CEC was relatively high.These provide a scientific basis for planting grass and trees on a fit place and to dispose urban landscape plants in a scientific and rational way.
