摘    要:通过对广州市内老八区道路绿化土壤的野外调查取样和实验室内土壤理化性质的分析,发现相当部分路段的土壤质量不符合要求:如种植土层薄、建筑废弃物多;pH值较本地自然土壤高,大部分呈中性和弱碱性;EC值低,肥力不足,供肥能力差;有机质含量低;速效钾缺乏,全氮、水解性氮和全磷严重缺乏;并提出一些改良措施。

关 键 词:道路绿化  土壤  调查  供肥能力

Abstract:After field investigation and physics properties and chemistry characters analysis on road greening soil from 8 former Districts of Guangzhou, we found quite a number of samples of soil from some roads are unqualified according to regulations. Such aspects can not meet requirements as: planting soil is thin; too much construction rubbish exists in it; pH of soil is higher than natural soil in the neighborhood, that is, most of soil samples are neutral or alkalescent; the EC is low; soil fertility is poor; the ability to supply nutrients is limited; organic matter content is low; available P, total N, hydrolyzed N and total P are seriously deficient. At the same time we recommend some measures to improve the current condition of road greening soil in Guangzhou.
Keywords:road greening  soil  investigation  soil fertility
