| 摘 要： | 为查明宁乡县植烟土壤养分丰缺状况，对宁乡县9个产烟乡镇的154个土壤样品的主要理化性状进行分析。结果表明：全县植烟土壤平均pH 5.79，有机质43.60 g/kg，碱解氮174.38 mg/kg，速效磷19.38 mg/kg，速效钾87.81 mg/kg，交换性镁1.36 cmol/kg，有效硼0.40 mg/kg，有效锌1.74 mg/kg，有效硫28.35 mg/kg。全县植烟土壤pH和有效锌、有效硼、交换性镁含量适宜；有机质、碱解氮含量较高；部分乡镇有效硫、速效磷含量偏高，速效钾供应明显不足。不同植烟乡镇土壤肥力特征有较大的差异。提出降氮、控磷硫、增钾、适当补施微肥的施肥建议。

| Abstract: | In order to investigate nutrients in tobacco growing soils of Ningxiang county, 154 soil samples were collected and analyzed from 9 tobacco growing towns in Ningxiang county. The results showed that the average soil pH value was 5.79, the average contents of organic matter was 43.60 g/kg, available N was 174.38 mg/kg, available P was 19.38 mg/kg, available K was 87.81 mg/kg, exchangeable Mg was 1.36 cmol/kg, available B was 0.40 mg/kg, available Zn was 1.74 mg/kg, available S was 28.35 mg/kg. The pH value, ... |
