不同烤烟品种富集土壤重金属的效应
Accumulative characteristics of heavy metal for various types of flue cured tobacco
摘要
Abstract
To understand accumulative differences of heavy metals among different varieties of flue cured tobacco, field experiment was conducted to measure plumbum( Pb) , cadmiun( Cd) and arsenic( As) concentrations in tobacco leaves at bottom, middle and upper side of stem by single factor randomized block design. Agronomic characteristics were measured to compare potential impact of heavy metal on quality of flue cured tobacco. Results revealed that heavy metal enrichments differed among tobacco varieties. Heavy metal enrichments were relatively higher in Yunyan 87, Yunyan 97, Yueyan97 and K326 than NC71, NC297, CZ43 and Yunyan 99. Varieties which had stronger heavy metal enrichment effect usually had predated foot leaf yellowing, shorter developmental peri-od, and poor agronomic performance especially in vigorous growth period, however, delayed foot leaf yellowing, lengthened develop-mental period, and good term agronomic performance in vigorous growth period occurred in tobacco varieties which were low in heavy metal accumulation.关键词
