2008-2009年对长汀县烤烟种植地烟前烟后土壤养分测定表明,烤烟耕地土壤整体较酸,全县土壤烟前pH值为4.31,烟后4.42;有机质含量处于中等水平,烟后土壤有机质含量26.33 g·kg-1,比烟前(24.69 g·kg-1)有所增加;植烟后土壤碱解N含量与植烟前差别不大,略有增加,含量处于中等水平;速效P含量较为丰富,植烟前土壤速效P含量为44.18mg·kg-1,植烟后显著增加,达60.25 mg·kg-1;速效K含量植烟前偏低,仅75.17 mg·kg-1,植烟后增加显著,达324.87 mg·kg-1,烟后土壤速效K含量丰富。不同土属pH值差别不大,有机质含量、碱解N、速效P、速效K以黄泥田、灰泥田、紫泥田、潮沙田较高。
2008-2009年對長汀縣烤煙種植地煙前煙後土壤養分測定錶明,烤煙耕地土壤整體較痠,全縣土壤煙前pH值為4.31,煙後4.42;有機質含量處于中等水平,煙後土壤有機質含量26.33 g·kg-1,比煙前(24.69 g·kg-1)有所增加;植煙後土壤堿解N含量與植煙前差彆不大,略有增加,含量處于中等水平;速效P含量較為豐富,植煙前土壤速效P含量為44.18mg·kg-1,植煙後顯著增加,達60.25 mg·kg-1;速效K含量植煙前偏低,僅75.17 mg·kg-1,植煙後增加顯著,達324.87 mg·kg-1,煙後土壤速效K含量豐富。不同土屬pH值差彆不大,有機質含量、堿解N、速效P、速效K以黃泥田、灰泥田、紫泥田、潮沙田較高。

The pH,organic matter,available nitrogen,available phosphorus and available potassium were investigated in tobacco-planting soil of Changting County from 2008 to 2009.The result showed that most of the soils were generally acidic,the pH was 4.31 before tobacco planting,and 4.42 after tobacco harvest.The content of organic matter was moderate,it was 26.33 g·kg-1 after tobacco harvest,higher than that before tobacco planting(24.69 g·kg-1).The content of available nitrogen was at the medium leve1 after tobacco harvest,which was the same as that before tobacco planting.The content of available phosphorus was rich,it was significantly increased after tobacco harvest(60.25 mg·kg-1) as compared with that before tobacco planting(44.18 mg·kg-1).The content of available potassium was significantly richer after tobacco harvest(324.87 mg·kg-1) than that before tobacco planting(75.17 mg·kg-1).Among different soil types,the pH was not significantly different,but the content of organic matter,available nitrogen,available phosphorus and available potassium was higher in yellow paddy,marl field,purple paddy,tidal sandy paddy.
