摘要
[目的]探明贵州省黄平县生态区优质烤烟的最佳移栽时期。[方法]分别考察5个移栽期处理的烤烟在团棵期、现蕾期的农艺性状,以及不同移栽期处理对烤烟自然抗病性和主要经济性状的影响。[结果]不同移栽期处理对烟株的生长动态影响各异,烤烟的生长与气温、日照时数、降雨量和栽培管理方式密切相关;不同移栽期处理的烟株对赤星病的抗性差异不显著。[结论]贵州省黄平县烤烟的适宜移栽期为4月中旬至下旬。过晚移栽则降低烟叶的产量和品质,使经济效益下降。
[Objective] The optimal transplanting period of high-quality flue-cured tobacco in ecological regions of Huangping County, Guizhou Province was explored. [Method] Agricultural characters of flue-cured tobacco in rosette stage and budding stage during 5 transplanting periods were investigated, and influence of different transplanting periods on disease-resistance and major economic characters of flue-cured tobac- co was also studied. [Result] Different transplanting periods influence growth conditions of flue-cured tobacco to dif- ferent degrees, growth of tobacco is closely related to temperature, sunshine duration, precipitation, cultivation and management style. Different transplant- ing periods has slight influence on the resistance of flue-cured tobacco against tobacco brown spot. [Conclusion] The optimal transplanting period of flue- cured tobacco in Huangping County lasts from middle to late April. Flue-cured to- bacco should not be transplanted too late because yield and quality of tobacco leaf will decline, and economic benefits will degrade.
