摘要: 为探究不同种植密度和施氮量处理,对烟叶组织结构及品质的影响。以粤烟98为试验材料,通过大田试验,采用随机区组排列,设置6个不同种植密度和施氮量组合的处理,分别于叶长30 cm、定长、适熟时采集中上部新鲜叶片,并利用石蜡切片制片方法,观察叶片组织结构。结果表明:栅栏组织厚度、海绵组织厚度、叶片厚度、栅栏组织密度均随着种植密度增加而减小,随着施氮量增加而增大;栅栏组织厚度、海绵组织厚度、叶片厚度、栅栏组织密度及比叶重与烤烟生育期化学成分总糖含量、还原糖含量、淀粉含量呈显著或极显著负相关,与烟碱含量、总氮含量呈显著或极显著正相关(个别数据除外);烤后烟叶总糖含量、还原糖含量、淀粉含量均随种植密度和施氮量的增加而减小,烟碱含量和总氮含量均随种植密度的增加而减小,随施氮量的增加而增加。因此,通过改变种植密度和施氮量可以改变叶片组织结构的发育特征,协调烟叶内部化学成分含量,最终达到改良烤烟品质目标。

关键词: 烤烟, 种植密度, 施氮量, 组织结构, 化学成分

Abstract: To investigate the effects of tobacco organizational structure development and chemical composition with different planting density and N application rate.Field experiment was carried out using Yueyan 98 as planting materials.Set up six different planting densities and N application processing.Respectively,in leaf length 30 cm,fixed length,mature collected in the upper and central part of fresh leaves and use paraffin methods,observe the organizational structure.The results showed that the thickness of palisade tissue,spongy tissue thickness,leaf thickness,palisade tissue density with the increase of planting density decreases with increasing nitrogen rate increases;the thickness of palisade tissue,spongy tissue thickness,leaf thickness,palisade tissue density,SLW and tobacco quality indicators total sugar,reducing sugar content,starch content was significantly or very significantly negatively correlated with nicotine content,total nitrogen content were significantly or very significantly positively correlated except for individual date;after roast total sugar content,sugar content,starch content increased with the increase of planting density and nitrogen application rate decreases,the nicotine content and total nitrogen content increased with planting density decreases with increasing nitrogen rate increases.By changing the planting density and nitrogen application rate can be varied leaf development characteristics of the organizational structure,internal coordination chemical composition of tobacco,and ultimately improve the quality of tobacco.

Key words: Flue-cured tobacco, Planting density, N application rate, Organizational structure, Chemical composition
