Comparative Analysis on Physicochemical Characteristic of Tobacco Planted in Rice Paddy and Mountain Area

The study mainly analyzed the physicochemical characteristics of tobacco planted in rice paddy and mountain area in Hunan.The results showed the physicochemical indicators of tobacco in the soil of rice paddy and mountain reached the significant differences and very significant differences.Among the results,the indicator of containing terrier of the tobacco planted in mountain area was higher than that of the rice paddies,but the indicators of dry matter removed stems and the leaf weight of elemental area were lower than those of the rice paddies;The physicochemical characteristics of tobacco planted in rice paddy were more steady than that of the mountain area,the total sugar,total nitrogen,potassium,chloride,the content of total sugar and reducing sugar of tobacco in the soil of the rice paddy were obviously higher than those of the mountain area,but nicotine,potassium chlorine ratio of the tobacco in the soil of the rice paddy were lower;There was a significant difference in the indicators,including the β-carotene,lutein,rutin content,but the difference was not significant in the content of chlorogenic acid,the content of the β-carotene and rutin in the tobacco of the soil of rice paddy was higher,while,the content of lutein was lower.
