摘要
2011年对永州市53个种烟乡镇的629个植烟土壤的微量元素有效养分进行了取样调查和统计分析,结果表明:永州烟区植烟土壤有效铜、铁、氯含量丰富,极少缺乏;土壤有效锌、钼、锰部分缺乏,应适当补充;95%以上的土壤有效硼处于缺乏状态,应大范围补充。聚类分析将永州烟区植烟土壤微量元素含量划分为4大特征区域,应根据土壤养分分布特征,合理施用微量元素肥料。
The contents of available trace elements of 629 soil samples collected from 53 tobacco -growing towns of Yong-zhou city were investigated and statistically analyzed in 2011.The results showed that the contents of available Cu,Fe and Cl were rich in tobacco -growing soil of Yongzhou.The contents of available Zn,Mo and Mn were partly lack,and which should be appropriately complemented.Available B in 95% of soil samples was deficiency in the soil,and which should be widely complemented to tobacco -growing soil.Based on the content of trace elements,tobacco -growing soil of Yong-zhou was clustered into 4 groups.Trace element fertilizer should be applied properly according to the nutrient distribution properties.
