摘　　要：为探明新宁县主产烟区土壤养分特征,提高新宁烟叶的产量和质量,采集新宁县主要烟区高桥、巡田、马头桥等8个乡镇的73份典型烟田耕作层土样,对土壤的pH值、主要养分含量、中微量元素含量进行分析。结果表明:8个主要烟区土壤偏酸性;土壤中有机质、氮元素、有效磷的含量较高,钾元素含量较低;中微量元素氯、镁、钙、锰和钼比较缺乏,尤其是氯和镁含量极低。试验结果可为新宁县的烟叶生产和配方施肥提供参考。In order to explore the characteristics of soil nutrient in the main tobacco-planting areas and improve the yield and quality of tobacco leaves in Xinning County,73 soil samples were collected from 8 towns in the main tobacco areas of Xinning County,including Gaoqiao,Xuntian and Matouqiao.The pH of the soil,the contents of main nutrients and the contents of medium and trace elements were analyzed.The results showed that the soil in 8 main tobacco areas was slightly acidic,the contents of organic matter,nitrogen and available phosphorus were high,the content of potassium was low,the trace elements chlorine,magnesium,calcium,manganese and molybdenum were deficient,especially the contents of chlorine and magnesium were very low.The experimental results can provide reference for tobacco production and formula fertilization in Xinning County.
