火山灰石砾对烤烟生长及产质量的影响
Journal of Yunnan Agricultural University(Natural Science)(2012)
Abstract
在云南腾冲通过田间试验研究了在土壤中加入15%火山灰石砾对烟株生长、病害、烤后烟叶产量、化学成分及色素和多酚含量的影响。结果表明,水田试验添加火山灰石砾处理烟株在前期生长较快且差异显著(P<0.05),烤后烟叶产量产值分别达3 247.05 kg/hm2,57 148.08元/hm2,显著(P<0.05)高于对照处理,化学成分更协调,类胡萝卜素含量较高,处理间多酚含量无明显差异;旱地试验添加火山灰石砾处理烟株赤星病和普通花叶病发病程度显著(P<0.05)低于对照,烤后烟叶产值、中上等烟比例及均价分别为48 407.13元/hm2,72.10%和17.3元/kg,显著(P<0.05)高于对照处理,化学成分更协调,处理间色素和多酚含量无明显差异。
