江西不同类型紫色土有效硫含量特征及其对烟叶硫分布规律的影响
Characteristics of Available Sulfur Content in Different Types of Purple Soil of Jiangxi and Their Effects on Sulfur Distribution in Flue -cured Tobacco Leaves
摘要
Abstract
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.关键词
