摘要: 为探讨烤烟涝害救治施肥技术问题,采用盆栽试验方法研究土壤渍水下不同形态氮源对烤烟生长的影响。结果表明:在不同氮源营养条件下,烤烟对土壤渍害的反应明显不同,排水后恢复生长的能力也不同。烤烟受渍后株高、单株叶面积、心叶延伸速率、叶片N含量、生物产量均明显降低。1/2NH4+-N+1/2NO3--N营养的植株单株叶面积、心叶生长率速率、生物产量均高于单一NH4+-N营养和单一NO3--N营养。增铵营养使烤烟生长对渍害的敏感性有所提高。3种氮源下,均是叶生长对渍害最敏感,其次是茎,根系生长对渍害反应相对钝感。

Abstract: In order to study the problem of fertilization technology for treatment of the waterlogging flue-cured tobacco, the pot experiment was adopted to study the effects of different N source on growth of flue-cured tobacco under soil waterlogging in 2010. The results showed that soil waterlogging markedly lowered the plant height, the individual green leaf area, the growing rate of central leaf, the leaf N content and biomass. On any condition, the in green leaf area of flue-cured tobacco in condition of 1/2NH4+-N+1/2NO3--N, its growing rate of central leaf and its biomass were greater than those of NO3--N and those of NH4 +-N. The addition of NH4 + nutrition seems to enhance the sensitivity of flue-cured tobacco growth. The sensibility of different organ in flue-cured tobacco plant to soil water logging were different: leaf>stem>root.
