    摘要:

    对鄂西南植烟土壤微量元素含量状况的统计分析表明,该区域缺乏及潜在缺乏土壤水溶性B面积达80%以上,土壤Zn缺乏面积达50%左右,60%以上土壤有效Cu含量较低,98%的植烟土壤水溶性Cl含量偏低,为了提高烟叶的产量和品质,在生产上应重视这些微肥的施用;植烟土壤有效Mo含量变幅范围较宽(痕量~3.3 mg/kg),不同生产区域差异较大,施用Mo肥应因地制宜。经过20多年的耕种等措施,该区域植烟土壤缺Zn、Cu、B的面积有一定的减少,与1982年相比分别约下降了11.5%、25.4%和24.2%,但不同烟区表现的规律不尽一致。

    Abstract:

    Micro-element status of tobacco soils in Southwest Hubei province was statistically analyzed. The results showed that ① 81.1% of the soils were deficient or potentially deficient in water soluble B; 60% in available Zn, 60% in available Cu and 98% in available Cl. To improve yield and quality of the tobacco crop, the fertilizers recommended for tobacco should contain the above mentioned elements. ② Soil available Mo content varied in a relatively wide range (0~3.3 mg/kg), and varied greatly across the tobacco region. Mo fertilizers should be applied according to the local soil Mo status. ③ After more than 20 years of tobacco cultivation and management, the percentage of soils deficient in Zn, Cu and B decreased by 11.5%, 25.4% and 24.2%, respectively. But no uniform law could be deduced fitting different tobacco production zones.
