摘要
针对近年来贵州省龙里地区植烟土壤中频繁出现的疑是烟草锰中毒现象,本项目在发病区植烟土壤中采集了60个土壤和烟草样品,通过检测采集样品中总锰、有效锰、烟草中锰和p H等指标,揭示土壤中总锰、有效锰、p H值与烟草中锰的相互关系。试验结果显示:龙里县烟区土壤中总锰、有效锰和烟草中锰含量普遍高于全国平均水平,属于容易发生烟草锰中毒的区域。对龙里县烟区土壤中总锰、有效锰、p H值与烟草中锰含量的相互关系研究发现:土壤中总锰与有效锰呈正相关,烟草中有效锰含量与土壤p H值呈负相关,土壤总锰与烟叶中锰含量相关性不显著,土壤有效锰含量与烟叶中锰含量的相关性亦未达到显著水平。
According to investigating the suspected phenomenon of manganese toxicity in tobacco-growing soils, Longli county, Guizhou province, the 60 representative samples from tobacco-growing soils were collected and tested. The results show that the average content of total manganese, available manganese in soils and the manganese in tobacco leaves are higher than the average level in China. It demonstrated that Longli county could belong to sensitive areas prone to manganese poisoning. The study also found that the content of total manganese is positively corre- lated with available manganese concentration in soil and available manganese concentration is negative correlated with pH. Meanwhile available manganese and the tobacco leaves manganese have no significant correlation.
