Based on current balanced fertilization in Jianshi County Enshi State,soil nutrient status in the area where originally planted burley tobacco was analyzed,and the effect of balanced fertilization on the production and quality of tobacco under special soil condition was discussed, and a balanced fertilization management system in the area where originally planted burley tobacco for replanting flue-cured tobacco now was pre-liminary established.

为筛选出高产优质白肋烟新品种(系),对2937、27039、1045、2949、27011、B0833、2619和鄂烟1号(对照)等8个白肋烟品种(系)进行区域试验.结果表明,烟叶产量和产值上,以2937最高,1045、2949、27011、2619与对照相差不大,B0833和27039最低;外观品质上,以2937和B0833较好,2949、27011和2619稍差,27039和1045最差;抗黑胫病以2937、1045、2949、27011和2619为高抗,27039中抗,B0833为感病型.综合分析,各品种(系)中以2937表现最好.

随着社会的发展和生活水平的日益提高,作为特殊消费品的烟叶其质量与安全问题也得到越来越多人的关注,有机烟叶的研究和生产亟待开展和推广.在地理条件和气候条件优越的恩施烟区,开展有机烟叶生产有着得天独厚的条件,同时探讨有机烟叶生产的条件和模式也是现代烟草农业发展的必然要求,是实现烟草产业持续、高效发展的不可或缺的组成部分.介绍了有机烟叶的生产现状和生产体系要求,分析其发展前景和优势,以供参考.

Seven Burley tobacco varieties 99P211,OB122,9026,2126,22081,2406 and the contrast Eyan 1 were tested.The results showed that the production and value of 9026 was the best,good leave appearance and anti-Hollow stalk.2126 was good production and value,anti-Hollow stalk strongly,but its leave appearance was a little worse than the contrast's.2406 was good production and value,but worse leave appearance to the contrast and heavy incidence of Hollow stalk.22081,OB122,leave appearance near the control,but worse production and value to the contrast,bad anti-Hollow stalk.99P211 good leave appearance,but obviously lower production and value to the control and heavy incidence of Hollow stalk.
