| 摘 要： | 对云南省部分地区烤烟土壤适宜pH值范围缓冲研究结果表明,1982年与2 0 0 2年相比2 0年中土壤pH值平均变小0 .30 ,占总平均值的4 .8%。山地土壤一般酸性较强,而发达地区土壤酸性变化更多。故云南省某些地区应施一定量Ca(OH) 2 以调节酸碱度

| Abstract: | The range of suitable pH value of tobacco soil in part areas of Yunnan Province was studied.The results show that compared with 1982,the average of pH value diminishes 0.30 in 2002,accounting for 4.8% of the general average of pH value.The acidity is high in mountain soil,and the acidity changes fast in the soil of advanced areas.Ca(OH) 2 should be applied to regulate the soil pH value in some areas of Yunnan Province. |
