| 摘 要： | 为探明影响烤烟连作障碍的土壤养分含量因素,对我国湖南、贵州、云南三大烟区烤烟连作与轮作土壤进行了样品采集与分析,并对植烟土壤养分含量及相关性进行了研究.结果表明,各烟区土壤养分共性特点是土壤有机质、土壤全氯、土壤碱解氮含量均比轮作土壤低(P＜0.05),而各烟区连作和轮作土壤全磷、Olsen磷、全钾、交换性钾的含量有所不同.相关性表明,土壤有机质、全氮和碱解氮极显著相关(P＜0.01),碱解氮与全磷、全钾负相关(P＜0.01),Olsen磷与土壤有机质、全氮、碱解氮极显著负相关(P＜0.01),交换性钾和其它养分不相关,仅与土壤pH相关. |

| Abstract: | To explicit the complication of the effect of soil nutrient content on flue-cured tobacco monocropping obstacle,soil of three main flue-cured tobacco growing areas were randomly collected,and regular nutrient contents were determined and analyzed.The diversity and relativity in different tobacco-growing areas were researched.The aim is to provide the theory about the soil of monocropping obstacle adjustment and control measurement.The results showed:the common characteristics was about the soil organic matt... |
