Effects of Different Preceding Crops on Quality of Flue -cured Tobacco in Qujing Area
摘要
Abstract
The chemical composition, aroma substance, smoking quality and heavy metal content of flue -cured tobacco with different preceding crops were studied in two different altitudes of ecological tobacco areas of Qujing city, Yunnan province. The results showed that the preceding crop had great influence on the quality of tobacco leaves, and the tobacco leaf quality had a little difference among different altitudes. In the tobacco areas with middle and low altitudes (1300 ~ 1800 m), the chemical composition was considered as the best when the preceding crop of flue - cured tobacco was com or pea; while it was considered as the best when the preceding crop was broad bean or corn at high altitude (1800 -2300 m). The aroma substance content could be appropriately increased by taking corn, green manure or pea as the preceding crop at middle and low altitudes and taking green manure or com as the preceding crop at high altitude. The score of smoking sensory quality of tobacco leaves was higher when corn, green manure, pea or rape was taken as the preceding crop at middle and low altitudes and green manure or com was taken as the preceding crop at high altitude. Delicate fragrance style was the most obvious when green manure or rape was planted as the preceding crop at middle and low altitudes and yam or com was planted as the preceding crop at high altitude. The lead content in tobacco leaves in Qujing area was higher, but the lead content was the lowest when the preceding crop was blank at middle and low altitudes or yam at high altitude. In conclusion, taking com or pea as the preceding crop at the middle and low altitudes and taking green manure or corn as the preceding crop at high altitude were most beneficial to the improvement of the tobacco leaf quality.关键词
