双转光地膜对烟草生长与生理特性及地温的影响

Effect of dual-sunlight conversion film mulching on soil temperature, growth and physiological characteristics of tobacco

    摘要
  • 摘要: 双转光地膜能较好地将烟叶色素吸收低的紫外光和绿光转化为红光和蓝光.大田栽培试验表明双转光地膜具有显著增加地温和促进烟株生长的作用.烟垄覆盖双转光地膜可使5 cm日平均地温增高1℃,10～15 cm日平均地温增高0.8℃,并显著增加烟苗根、茎、叶干重,促进烟苗早生快发,有利于尽早增大光合叶面积.烟叶化学成分分析表明,双转光地膜处理未对烟叶品质产生不良影响.
