| 摘 要： | 本文以南京市南郊蔬菜地土壤为研究对象,全面调查了蔬菜地土壤有机质、全N、全P、全K、速效P、NO3--N等养分指标的累积状况。调查结果显示,与水稻田土壤相比,土壤养分均有不同程度的累积,尤以大棚土壤速效P、NO3--N的累积为甚;但与第二次土壤普查资料相比,土壤有机质、全K均有不同程度的下降,全P略有上升。平衡的施肥制度和合理的耕作管理体系是保持土壤养分平衡的关键。 |

| Abstract: | Nutrients in vegetable soils in south suburb of Nanjing were investigated. The results showed that nutrients in vegetable soil accumulated, compared to those in paddy soil. NO3--N and readily available P accumulated the most in the soil in plastic greenhouse. But organic matter, total nitrogen and total potassium decreased below those in 1980s. Total phosphorus increased over those in 1980s. |
