低海拔综合配套技术对烤烟生长发育及产质量的影响

Effects of comprehensive matching techniques in low altitudes on growth yield and quality of flue-cured tobacco

以烤烟云烟87为研究对象,研究了低海拔综合配套技术对烟株生长发育的农艺性状、经济性状和烤后烟叶化学成分的影响。结果表明,通过生产技术措施的调整,烟株的农艺性状、化学成分和经济性状表现为T2与T1、T3之间差异显著,但T1、T3之间差异不显著;3个处理的产量、产值和均价都表现为T3>T1>T2,T1、T3的化学成分协调,T2的协调性不足;上等烟比例表现为T1>T3>T2。通过对烟叶生产技术措施的调整,使巫山烟区低海拔生产的烟叶内在质量较好,化学成分协调,烟叶的产量产值高,与当前巫山烟区生产的烟叶产质量基本一致。

Taking the flue-cured tobacco variety Yunyan 87 as the research target,the effects of low altitude comprehensive technology on agronomic characters,economic characters and chemical composition of flue-cured tobacco were studied.The results show that there are significant differences in agronomic traits,chemical composition and economic traits among T2,T1 and T3,but there are no significant differences between T1 and T3.The performance of the 3 treatments in yield,output value and the average price are T3>T1>T2.Meanwhile,the proportion of all the chemical components in T1 and T3 are appropriate while not in T2.As for the first-class tobacco proportion,the result is T1>T3>T2.By adjusting the technical measures of the tobacco production,the tobacco leaves have good inner quality,proper chemical components proportion and high yield and output value,which is broadly in line with the overall quality of the tobacco in Wushan.
