摘要
通过了解云南部分地区不同年代土壤pH值的情况,以及测定土壤的pH值缓冲曲线,对照适宜植烟土壤pH值范围,结果显示应该在云南省某些地区施一定量的Ca(OH)2以调节酸碱度。
The different ages and region soil pH were invested in Yunnan.Suitable tobacco growth soil pH range were checked by pH buffer curvilinear illustration.The resuls showed that certain quantity of Ca(OH)2 would be applied in some region of Yunnan forregulat soil pH.
