贵州植烟土壤微量元素含量状况与微肥施用

20 0 0年对贵州省主要植烟土壤微量元素进行了普查。结果表明 ,全省植烟土壤中铁、锰非常丰富 ,平均含量分别为 37.16mg kg和 4 4 .6 4mg kg ;钼丰富 ,平均含量为 0 .2 4 3mg kg ;铜、锌中等 ,平均含量分别为 1.812mg kg和 1.5 84mg kg ;硼缺乏 ,平均含量为 0 .338mg kg。各烟区与各土壤类型微量元素含量差异明显。针对土壤中微量元素状况 ,提出了贵州烤烟生产中微肥施用的措施

Content of microelements in tobacco soil and application of micro-fertilizers in Guizhou

The content of microelements in major tobacco soils in Guizhou Province was generally investigated in 2000. The results showed that all the tobacco soil were very rich in Fe and Mn with an average of 37.16 mg/kg and 44.64 mg/kg respectively; rich in Mo, 0.243mg/kg; moderate in Cu and Zn, 1.812 mg/kg and 1.584 mg/kg respectively; poor in B, 0.338mg/kg. The content of microelements differed obviously among different areas and soil types. Based on the obtained results, the practices of fertilization for flue-cured tobacco production in Guizhou Province were also put forward.
