摘　　要：[目的]探索低纬度高海拔地区红花大金元最佳移栽期。[方法]在云南省红河州弥勒市西一镇植烟区域设置4月1日、4月10日、4月20日、4月30日、5月5日(CK)5个不同移栽期,研究不同移栽期对红花大金元移栽后烟株成活率、农艺性状、病虫害情况、经济性状的影响。[结果]在弥勒市烟区,4月1日移栽处理能够有效避开烟草黑胫病病原菌的侵染,发病率、病情指数比常规移栽低,烟苗早生快发,延长了大田生育期,有利于干物质积累和烟叶成熟,在主要经济性状指标上表现较好。[结论]在弥勒市西一镇及气象条件相似的植烟区红花大金元烟苗适宜移栽期为4月1日。[Objective] To explore the optimal transplanting period of Honghuadajinyuan in low latitude and high altitude areas. [Method]Five different transplanting dates were designed in tobacco planting area of Xiyi Town,Mile City,Yunnan Province,which were April 1,April10,April 20,April 30 and May 5（ CK）. Effects of different transplanting dates on the survival rate,agronomic trait,diseases and pests,economic characters were researched after transplanting of Honghuadajinyuan. [Result] In tobacco area of Mile City,transplanting treatment in April 1 could effectively avoid the infection outbreak of tobacco black shank,and reduced the incidence rate and disease index compared with conventional transplanting. Early growth and quick tillering of tobacco seedlings prolonged the growing stage in field,was helpful to the accumulation of dry matter and the maturity of tobacco leaves,and had relatively good performance in main economic indicators. [Conclusion]The proper transplanting date of Honghuadajinyuan was April 1 in Xiyi Town,Mile City and other planting areas with similar meteorological conditions.
