The Chemical Composition Analysis of Flue-cured Tobacco Leaves between Positions on the Stem in Lijiang
摘要
Abstract
In order to reasonably make use of tobacco recourses, a routine chemical composition analysis of 347 flue-cured tobacco samples from 37 sampling points in Lijiang area was conducted. The results showed that; (1) the content of total sugar and the content of reducing sugar in Lijiang area was much higher with the highest ratio of 34. 39% and 27. 70% in Gucheng and the lowest ratio of 27. 07% and 19. 33% in Huaping . The content of potassium was averagely lower with the highest ratio of 1. 88% in Gucheng and the lowest ratio of 1. 26% in Huaping. With the raise of leaf position, the content of total sugar and reducing sugar firstly increased and then decreased, the content of nicotine and the total nitrogen content gradually increased and the content of potassium gradually reduced. ( 2)In different leaf positions, there was a very significant negative correlation between carbon compounds and nitrogen compounds. The correlation between the potassium content and the carbon compounds as well as the nitrogen compounds was not remarkable. In different areas of Lijiang, The correlation between the carbon compounds and the nitrogen compounds in Ninglang and Gucheng areas was not remarkable , which in other areas was a negative correlation. There was not a very significant correlation between the content of potassium and the carbon compounds in Yulong and Gucheng, but which there was a very significant negative correlation in other areas. The correlation between the potassium content and the nitrogen compounds in Ninglang was not remarkable, but which was a very significant negative correlation in other areas. (3 ) Lijiang area was classified into three categories. I contained Gucheng. The chemical compositions in the total sugar, reducing sugar, nicotine, potassium and total nitrogen here were respectively 34. 39% , 27. 70% , 2. 06% , 1. 88% and 1. 44% .II contained Yu Long, Ninglang and Yongsheng. The chemical compositions were respectively 29. 11% , 22.35% , 3.04%, 1.55% and 1.74%. III included Huaping. The chemical compositions were respectively 27.07%, 19.33%, 3.47%, 1.87% and 2. 10%.关键词
