Effects of applying lime on the properties of acid soil and the leaves quality in flue-cured tobacco
|
Abstract:
The effect of applying lime in acid soil on soil biochemical properties, leaves growth and quality of flue-cured tobacco was examined. The results show that applying lime in acid soil can not only increase the quantities of soil bacteria, actinomycetes and cellulose-decomposing bacteria but also significantly enhance the activities of soil urease, phosphatase, cellulosase and peroxidase. 750- 1125kg/hm of lime applied in the soil of pH5.2 can improve the root growth, yield and quality of tobacco leaves.
