恩施烟区小苗移栽时间对烤烟发育及产量和质量的影响

Effects of Young Seedling Transplanting Time on Growth, Yield and Quality of Flue-cured Tobacco in Enshi Tobacco-plantation

通过设置不同海拔区域烟株移栽期,研究了恩施烟区不同移栽期和不同海拔气候条件对烤烟生长与烟叶质量的影响。结果表明,在3个海拔烟区都表现出随移栽期的推迟,烟株生长期间对应的温度较高,烟株生长速度加快,烤烟生育期明显缩短。不同移栽期对烟株主要农艺性状和烤后烟叶经济性状有较大的影响,在低海拔烟区4月25日移栽、中海拔烟区5月5日移栽、高海拔烟区5月10日移栽的烟株主要农艺性状和烤后烟叶经济性状表现最优。

By setting different transplanting time at different altitudes, the effects of different transplanting time and climatic conditions of different altitude on growth and quality of flue-cured tobacco were studied. The results showed that with the transplanting period delayed, the corresponding temperature in plant growth period was higher, thus tobacco growth accelerated and tobacco growth period was shortened obviously in tobacco-plantation of three altitudes. Different transplanting period have great impact on the agronomic traits and quality of flue-cured tobacco. When transplanting on April 25 thin low-altitude districts,on May 5thin middle-altitude districts, and May 10 thin high-altitude areas, the agronomic and economic traits were the best.
