摘要
2010年对永州市50个种烟乡镇的629个植烟土壤样品的养分状况进行了调查分析。结果表明:永州烟区土壤pH总体偏碱性,土壤有机质含量较高,土壤氮、磷营养贮藏及供应水平较高,土壤速效钾供应相对不足。利用聚类分析法将50个乡镇土壤聚合为5种类型,总结了各类型土壤养分特征及施肥方法,指出生产上应遵循控氮、稳磷、增钾、施足基肥、早施追肥的原则。
Soil nutrient contents status were investigated and determined for 629 soil samples which were collected from 50 tobacco growing towns in Yongzhou city in 2010. The results showed that the soil pH in tobacco growing areas was alkalescency, content of soil organic matters was high, the level of N and P storage and accommodation in soil was slightly high, while available K in soil was insufficient. Using systematic cluster analysis, the author classified the soil of 50 tobacco growing towns into 5 types and then summarized the nutrient content characteristic and fertilization method related. Finally, this paper proposed fertilization principle ： to control N - Fertilizer fix P - fertilizer, increase K -tertilizer, fertilize basal fertilizer adequately and additional manure early.
