广西主烟区土壤和初烤烟中微量元素含量分析

对广西主烟区土壤和烟叶中微量元素进行了分析,结果表明:广西4个主烟区土壤铜、铁含量丰富,有8.62%土壤缺锰,18.57%的土壤严重缺锌;烟叶中铁含量偏高,锰含量偏低,锌含量适中。因此,在烤烟生产上要因地制宜,注意增施锌肥,控制铁肥,喷施锰肥。

Microelement content analysis of soil and flue-cured tobacco in main tobacco-growing areas of Guangxi

In this paper,microelement were analyzed in soil and leaves about the main tobacco-growing areas in Guangxi. The results showed that available Cu and Fe of soil in tobacco-growing areas were enrichment,8.62%of soil in tobacco-growing areas were short of Mn,18.57%of soil in tobacco-growing areas were short of Zn.Tobacco leaves were rich in Fe,poor in Mn and Zn were moderate.So it's to be adapted to local conditions in the flue-cured tobacco production.The fertilization suggestion of increasing the zinc fertilizer,controlling the iron fertilizer and spraying Mn was recommended.
