赣南烟区不同移栽期对烟叶生长状况及产质量的影响

目的]探讨赣南烟区适宜的烟草移栽期。方法]在赣南烟区石城县,研究不同移栽期(2月20日、2月25日、3月2日、3月7日、3月12日)对K326烟叶生育期、生物学性状及产质量的影响。结果]烟苗在3月7日前移栽可以缩短烟株大田生育期;3月7日以前移栽的烟株叶片大小比之后移栽的大,3月7日以后移栽的烟株有效叶片数增多,3月2、7日移栽的产值相对较高;对烤后烟叶X2F、C3F、B2F 3个等级的内在成分分析表明,3月7日移栽的烟叶内在成分各项指标在所有处理中最好。结论]该研究可为赣南烟区烤烟生产适宜移栽期的选择提供科学依据。

Effects of Different Transplanting Period on Growth, Development, Yield and Quality of Flue-cured Tobacco in the South Tobacco District of Jiangxi Province

Objective] The aim was to discuss the suitable tobacco transplanting period in the South District of Jiangxi Province. Method ] The effects of different transplanting periods（February 20, 25 and March 2, 7, 12） on K326＇s growth period, biological indices, yield and quality were analyzed in Shicheng County of the South Tubacco District in Jiangxi Province. Result] The results showed that tobacco seed- lings transplanted before March 7 could shorten its growth period in the field; the blade sizeof tobacco transplanted before March 7 was bigger and the number of its effective leaf was more than that transplanted after March 7, the production of that transplanted on March 2 and 7 were relatively high; the analysis results on internal composition of X2F, C3F, B2F three grades tobacco showed the tobacco component indices transplanted on March 7 were also good in all treatments. Conclusion] The study provides a scientifical basis for choosing suitable transplan- ting period of tobacco in the South Tobacco District of Jiangxi Province.
