摘　　要：为探明广东省菜地土壤肥力质量状况,对广东省广州增城,云浮罗定,清远连州和梅州五华4个典型县(市)进行了田间典型调查和取样分析。结果表明:土壤pH值在4.12～7.84之间,大部分处于弱酸到酸性范围。有机质含量在9.87～53.57 g/kg之间,大部分属中等偏上水平。碱解氮、铵态氮、速效钾、交换性镁和有效锰含量处于缺乏以下水平。硝态氮和有效硼含量处于中等缺乏水平。有效磷、交换性钙和有效铜含量大部分属中上水平。土壤电导率在36～497μS/cm之间,适宜一般作物正常生长。不同典型县(市)菜地土壤主要养分含量之间差异显著,建议结合当地种植制度及土壤养分特征平衡施肥,为土壤健康和蔬菜安全生产提供保障。In order to study vegetable field soil fertility quality in Guangdong province, field investigation, sampling analysis have been done in 4 typical demonstration counties （cities） of Guangdong province： Zengcheng, Luoding, Lianzhou and Wuhua. The results showed that the soil pH value was from 4.12 to 7.84, in weak acid to acid range mostly. Organic matter content was between 9.87-53.57 g/kg with most of the values at medium to high level. The contents of alkaline hydrolytic nitrogen, ammonium nitrogen, available potassium, exchangeable magnesium and available manganese were in shortage or drastic shortage. The contents of nitrate nitrogen and effective boron were at moderate or slightly lacking level. The contents of available phosphorus, exchangeable calcium, and available copper were above average level, mostly. Different fertilization treatments might caused strong variability of calcium and manganese. Soil Electrical Conductivity ranged from 36 to 497 ~S/cm, which was suitable for crops. There were significant differences between main nutrient concentrations in vegetable land soil from the typical counties （or cities） under consideration. In order to provide guarantee for soil health and vegetable safety production, balanced fertilization was suggested according to local plantation structure and characteristics of nutrient.
