不同移栽深度对烤烟翠碧一号生长及抗逆性的影响

Effects of Different Transplanting Depth on Growth and Stress Resistance of Flue-cured Tobacco

[目的]为寻找福建三明烟区生态条件下特色烤烟品种翠碧一号采用湿润育苗技术所育烟苗较为适宜的移栽深度。[方法]探讨翠碧一号湿润育苗烟苗浅栽、适度深栽和过度深栽对烤烟生长及抗逆性的影响。[结果]适度深栽有助于烟株早生快发,烟株根系发达,株型合理,田间整齐度较高,烟株生长较为老健,抗逆性有所提高,有助于提高烟叶的产量和产值,但对均价、上等烟比例及烟叶内在化学成分影响不明显。[结论]福建三明烟区生态条件下烤烟翠碧一号采用湿润育苗技术所育烟苗较为适宜的移栽深度约15 cm。

[ Objective] In order to to find the suitable transplanting depth of flue-cured tobacco varieties CB-1, and the tobacco seedling have cultivated on moist trays. [ Method] The effects of surface transplanting, moderate deeply transplanting and excessive deeply transplanting to growth and strdss resistance of flue-cured tobacco were discussed in Fujian Sanming ecological conditions. [ Result] The treatment of moderate deeply transplanting was helpful for early growth and quick tillering of tobacco plants, the root system was well developed, the plant type was reasonable, the field uniformity was higher, the growth was robust, the stress resistance was improved, and it could help to improve the yield and output, but the effects on the equal price, the rates of first class and the intrinsic chemical composition were not obvious. [ Conclusion ] Moderate deeply transplanting of 15 cm hole is more suitable for Moist seedling in Fujian Sanming ecological conditions.
