为减轻武平烟区在烤烟生长前期遭遇的低温危害影响,试验以云烟87为材料,研究了不同移栽深度对烤烟生长发育及产质量的影响。结果表明:适度深栽可以促进烟株生长发育,增强植株对低温冻害的抵御能力;以移栽深度为15 cm时各方面表现较为突出,其烤烟还苗早,进入团棵、旺长期快,大田生育期较长,农艺性状较优,烟叶外观品质较好,产量达183.64 kg/667 m2,上中等烟比例达99.46%,均价为24.51元/kg,产值达4 501.04元/667 m2。因此,在烤烟移栽过程中应提倡适度深栽,移栽深度以15 cm较为适宜。
In order to reduce the harmful effects of low temperature encountered in the early stage of flue-cured tobacco in Wuping tobacco-growing areas, the experiment was conducted to study the effects of different transplanting depths on the growth and yield and quality of flue-cured tobacco. The results showed that: Moderate deep planting can promote the growth and development of tobacco plants and enhance the plant’s ability to resist freezing damage. When the transplanting depth is 15 cm, the performance of tobacco plants is more prominent in all aspects. The growth period of the field was longer, the agronomic traits were better, and the appearance quality of the tobacco leaf was better. The output reached 183.64 kg / 667 m2, the upper middle-grade tobacco reached 99.46%, the average price was 24.51 yuan / kg and the output value was 4 501.04 yuan / 667 m2. Therefore, in the process of transplanting flue-cured tobacco should be promoted moderately deep planting, transplanting depth of 15 cm more appropriate.
