摘要
研究了不同氮肥种类对香料烟生长、光合速率、产量、产值及香气物质含量的影响.结果表明,施有机氮肥较无机氮肥处理的烟株,植株矮,叶片小,但生长后期叶片光合速率较高.有机氮肥中以施芝麻饼处理的产量、产值较高,无机氮肥中以施复合肥的产量、产值较高;A,B级烟叶比例,施芝麻饼处理的达87.3%～88.7%,复合肥为76.3%～78.2%,其它处理在80.0%～82.5%之间.施芝麻饼肥有利于提高香料烟典型香气物质含量及香气物质总量;施牛粪有利于提高香料烟特征香气物质赖百当类的含量;施KNO3处理的烟叶香气物质总量及典型香气物质含量明显高于施复合肥处理,与施牛粪处理的接近.
Studies were conducted on the effect of nitrogen fertilizer kinds on growth, photosynthetic rate, yield, value and content of aromatic matter of oriental tobacco.The results showed that when organic nitrogen fertilizer was applied,the plant height was lower and leaves were smaller,while the photosynthetic rate was higher in the latter stage of growth.The proportion of class A and class B leaf of oriental tobacco was 87.3%～88.7% when sesame oilcake was applied,76.3%～78.2% when compound fertilizer was applied and 80.0%～82.5% for other treatments.The yield and value of oriental tobacco were the highest by applying sesame oilcake among organic nitrogen fertilizers. The yield and value of oriental tobacco were higher and the total aromatic matter content of oriental tobacco were significantly lower when compound fertilizer was applied than when KNO3 was applied.Applying sesame oilcake could increase the typical aromatic matters and the total aromatic matter content of oriental tobacco.The characteristic aromatic matter such as labdanums was improved by applying cow dung.
