2、衡施肥,利用南平市植烟土壤普查资料,分析了土壤铁,锰,铜,锌,硼,氯养分状况与演变趋势,结果表明:土壤有效铁,锰,铜,锌,硼及水溶性氯含量分别为(88.494-62.66)rng/kg,(26.1l4-19.08)mg/kg,(3.154-2.01)mg/kg,(2.554-1.42)mg/kg,(0.264-0.19)mg/kg,(20.224-17.22)mg/kg;各养分变异系数均超过50%,属强变异.从各养分演变趋势分析,随着种烟年限增加,土壤供铁,锰能力均呈增加趋势,而供铜,锌,硼,氯能力
3、则呈降低趋势;从土壤保育和优质烟叶生产角度,应重视铁,锰营养过剩及铜,锌,硼,氯营养的补给.关键词:烤烟;土壤;微量元素;养分状况;演变趋势中图分类号:$153.6+1文献标志码:A论文编号:2011-0372EvolutionTendencyofSoilMicroelementsinNanpingTobacco-growingAreaChenZhihou,ChenChaoyang,XuQian.,WuPing,ChenXingfeng,XiongDezhong4(NanpingBranchofFu
