摘要
针对移栽和打顶时间两项影响烟碱积累的栽培措施进行了田间试验。用回归分析法分析表明，烟碱积累与打顶时间呈正相关，回归系数为0．1071，且达显著水平；与移栽时间呈负相关，回归系数为-0．025，也达显著水平。综合分析认为：适宜移栽期为5月25-30日，适宜打顶期应为盛蕾期。
The experiment was conducted to study the nicotine accumulation at different transplant and topping time in Mudaniiang, Nicotine accumulation was positively related to topping period, regression coefficient was 0. 1071. Nicotine accumulation was negatively related to transplant： period, regression coefficient was --0.025. The best period of transplant was on 25-30th, May, and the best period of top pruning was full bud time.
