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。
In 2008-2009, the soil nutrients of tobacco in Changting County before flue-cured tobacco cultivation showed that the overall soil of flue-cured tobacco was acid, the pH value of soil before flue-cured tobacco was 4.31 and 4.42 after smoke, the content of organic matter was moderate, The content of organic matter was 26.33 g · kg-1, which increased from 24.69 g · kg-1. The content of alkali-hydrolyzable N in soil after planting was not significantly different from that before planting, but increased slightly at medium level. (P <0.05). The content of available P in soil before tobacco planting was 44.18mg · kg-1, significantly increased after tobacco planting, reaching 60.25 mg · kg-1. The content of available K was low before planting, only 75.17 mg · kg-1 , After tobacco planting increased significantly, reaching 324.87 mg · kg-1, after-tobacco soil available K content is rich. Different soil genus pH value is not very different, organic matter content, alkaline hydrolysis N, available P, available K to yellow muddy fields, clay fields, purple clay fields, tidal fields higher.
