摘要
本试验以光泽县烤烟品种K326作为材料,分析了2018~2020年气候及其对不同移栽期的烟叶生育期、大田农艺性状、经济性状的影响。试验结果表明,2018年、2019年、2020年3个年度的不同移栽时间对大田烟叶生育期长短影响不大,但随着移栽期的不断提前,K326品种整体株型有矮化的趋势,加之2020年4月长期低温影响,造成烟株烟芽烟杈较多,烟株养分消耗过大,叶形狭长,对烟叶等级结构、产量、效益产生了严重的影响。将三年不同移栽期烟株大田整体表现及产量、效益情况比对,2月25~28日移栽的烟叶株型、产量和效益最佳;2月22~25日移栽的烟叶次之;2月20日~23日移栽的烟叶最差。
The paper analyzed the climate from 2018 to 2020 and its influence on tobacco growth period, agronomic character and economic character in different transplanting periods, using flue-cured tobacco K326 as material in Guangze County. The results showed that different transplanting periods had little effect on tobacco growth period from 2018 to 2020. However, with the advance of trans-planting period, the overall plant type of K326 had a trend of dwarfing. In addition, affected by the long-term low temperature in April 2020, more tobacco buds and branches, excessive nutrient consumption, narrow and long leaf shape, had a serious impact on grade structure, yield and economic benefits. By comparing the output, benefit and plant type performance of three years, it was found that the best transplanting date was February 25~28, followed by February 22~25 and February 20~23.
