摘  要:
为提高烟叶品质和经济效益,分析了植烟区土壤微量元素(有效铜、有效锌和有效钼)含量的分布频率和空间变化状况,绘制了微量元素空间分布图。结果表明:长顺县植烟土壤有效铜含量适中,丰富的土样占40%,有60%的土样有效铜含量低于缺铜临界值;有效锌含量适中,丰富的土样占95%以上,只有极少数土样有效锌含量低于缺锌临界值;有效钼含量适中,丰富的土样不足25%,75%以上的土样有效钼含量低于临界值。在空间区域分布上,有效铜、有效锌和有效钼均呈一定的区域性。

摘  要:
To enhance tobacco quality and economic benefits,the distribution frequency and space variation of trace elements(available Cu,available Zn and available Mo) in tobacco-planting soil were analyzed and space distribution map of trace elements was drawn.The results showed that about 40% of the soil available Cu content were medium and rich in tobacco planting areas of Changshun County,and available Cu was lower than the critical value with a percentage of 60% of the region.Above 95% available Zn contents were medium and rich,only a handful of soil was lower than critical value.Less than 25% available Mo contents were medium and rich,and above 75% were lower than critical value.As for the space distribution,available Cu,available Zn and available Mo contents were regional.
