土壤养分含量同海拔高度密切相关，为探索湖北巴东县茶店子基地单元不同海拔植烟土壤的理化性状，更好地指导巴东烟叶生产实践工作，对巴东县茶店子基地单元不同海拔植烟土壤的理化性状进行了分析。结果表明：（1）海拔800 m以下区域，植烟土壤理化性状特点是pH值、有机质、氮素、全磷含量处于适宜标准或以上，但速效磷和钾素含量较低；（2）800~1200 m区域，土壤pH值、氮素含量较为适宜，土壤有机质含量普遍偏高，但是磷素、钾素含量较低；（3）1200 m以上区域，除土壤pH值偏低以外，其他指标均处于优质烟叶生产范围内或高于标准。结合茶店子基地单元烟叶种植区划目标，建议在生产上采取“控氮、增磷、补钾”的施肥策略，施用充分腐熟的优质有机肥和适量土壤改良剂改良土壤，提高土壤养分利用率，进一步提高烟叶产量和质量。
土壤養分含量同海拔高度密切相關，為探索湖北巴東縣茶店子基地單元不同海拔植煙土壤的理化性狀，更好地指導巴東煙葉生產實踐工作，對巴東縣茶店子基地單元不同海拔植煙土壤的理化性狀進行瞭分析。結果錶明：（1）海拔800 m以下區域，植煙土壤理化性狀特點是pH值、有機質、氮素、全燐含量處于適宜標準或以上，但速效燐和鉀素含量較低；（2）800~1200 m區域，土壤pH值、氮素含量較為適宜，土壤有機質含量普遍偏高，但是燐素、鉀素含量較低；（3）1200 m以上區域，除土壤pH值偏低以外，其他指標均處于優質煙葉生產範圍內或高于標準。結閤茶店子基地單元煙葉種植區劃目標，建議在生產上採取“控氮、增燐、補鉀”的施肥策略，施用充分腐熟的優質有機肥和適量土壤改良劑改良土壤，提高土壤養分利用率，進一步提高煙葉產量和質量。

As the content of soil nutrient closely related to the altitude, thus analyzing the physiochemical characteristics of tobacco planting soil at different altitudes of Chadianzi base in Badong County, in order to better guide the practical production of tobacco leaves in Badong County. The results showed as follows:(1) The altitude of area under 800 m, the physiochemical characteristics of tobacco planting soil showed that the pH value and the contents of organic matters, nitrogen and total phosphor met the standards of appropriate level or beyond, but the contents of available phosphor and kalium were relatively low. (2) In area from 800 m to 1200 m, the pH value and the nitrogen content were suitable, but the content of organic matters was generally high, and the contents of phosphor and kalium were low. (3) In the area over 1200 m, except the pH value was relatively low, the other indexes were all in the range of quality tobacco leaves or beyond. Combined with the regionalization goal of tobacco planting in Chadianzi base unit, it suggested that adopting the fertilization strategies of“controlling N, supplying P, and increasing K”. In order to improve the utilization rate of soil nutrient and the yield and quality of tobacco leaves, it should apply the full maturity of organic fertilizers and suitable amount of soil amendment.
