为探明山地植烟土壤酸碱缓冲特性,采集了湘西山区烤烟典型生产区的28个土壤样本,采用酸碱滴定法和灰色关联法分析了湘西山地植烟土壤酸碱缓冲特性以及土壤缓冲容量与各影响因素之间的量化关系。结果表明:湘西山地植烟土壤酸碱缓冲量为11.35~43.29 mmol·kg~(-1),平均为17.26 mmol·kg~(-1),黄棕壤的酸碱缓冲量(11.35~43.29 mmol·kg~(-1))显著高于黄壤(11.79~20.70 mmol·kg~(-1))。有78.57%的样本对酸碱敏感,黄壤土是否对酸敏感由有机质含量决定,黄棕壤土是否对酸敏感与pH和有机质含量密切相关。对于同一土壤类型,有机质和黏粒含量与酸碱缓冲容量显著正相关;对于黄棕壤,酸碱缓冲容量还与pH和阳...

To determine the characteristics of pH buffer of soils cultivated with tobacco in the mountain regions that are under long-term fertilizer application, a total of 28 soil samples were collected in areas of typical flue-cured tobacco cultivation in mountain regions in western Hunan Province. The pH buffer characteristics of collected soils were analyzed using both titration curve and gray correlation methods. Then quantitative relationships and the driving factors of soil acid-base buffer characteristics were also investigated. The results showe...
