摘要
于2009年在江西紫色土烟区点对点采集土壤样与烟叶样进行化验,分析不同类型紫色土有效硫含量特征及对烟叶硫分布规律的影响,结果表明:江西紫色土有效硫平均含量较高,为90.4 mg/kg,而紫色土烟叶的含硫量为4.0 g/kg;酸性紫色土有效硫含量较低,约为中性与碱性紫色土有效硫含量的1/2;烟叶含硫量依次是碱性紫色土>中性紫色土>酸性紫色土,碱性紫色土种植烤烟更有利于烟叶对硫的吸收。不同紫色土烤烟其不同叶位的含硫量分布为上部叶>中部叶>下部叶。
In order to investigate the content of available sulfur in different types of purple soil of Jiangxi and their effects on sulfur distribution in flue-cured tobacco leaves,the purple soil and tobacco samples were collected in 2009 by using point-to-point sampling method,and then they were determined.The results showed that the average content of available sulfur in purple soil of Jiangxi was abundant（90.40 mg/kg）,but the average sulfur content in tobacco leaves from purple soil was 4.0 g/kg.The available sulfur content in acid purple soil was lower,being about half of that in the alkaline and neutral purple soil.The sulfur content in tobacco leaves from different types of soil had the following order： alkaline purple soil 〉 neutral purple soil 〉 acid purple soil,thus the alkaline purple soil was good for the absorption of sulfur by tobacco leaves.The sulfur content distribution in tobacco leaves from purple soil had the following law： upper leaf 〉 middle leaf 〉 lower leaf.
