施氮量对烤烟常规化学成分含量及主流烟气中7种有害成分释放量的影响
Effect of nitrogen application rate on routine chemical components in flue-cured tobacco and delivery of seven harmful components in mainstream smoke
摘要
Abstract
Field experiments with tobacco cultivar Yuyan No.12 were carried out to study effects of different nitrogen fertilizer rates on chemical components and 7 harmful components delivery in mainstream smoke.Results showed that different nitrogen fertilizer rates affected content of routine chemical compositions,and had influence on delivery of harmful components in mainstream smoke.Contents of protein,nicotine and total nitrogen increased,while total sugar and reducing sugar decreased with the increase of nitrogen fertilizer rate,while its effect on effect on potassium and chlorine content were not obvious.Nitrogen fertilizer rate had different effects on 7 harmful components in mainstream smoke.Crotonaldehyde decreased while ammonia and N-nitrosamines increased along with the increase of nitrogen fertilizer rate.When treated with 55 kg/hm2 nitrogen fertilizer,conventional chemical composition was coordinate,hazardous index of seven harmful components in mainstream smoke was lowest.关键词
