摘要
为探明烤烟移栽期与烟株生长发育的关系,研究了不同移栽期对贵烟5号花芽分化阶段主要生长特征的影响。结果表明:随着移栽期推后,烟株花芽分化开始和结束的时间相应延后、历时时间相应缩短;花芽分化开始时间为团棵后9~12 d,结束时间为现蕾后5~7 d,历时时间22~25 d;花芽分化开始时烟株的主要农艺性状以T3表现最佳,茎叶氮磷钾含量以T3最高,花芽分化结束时主要农艺性状以T2表现最佳,茎叶氮磷钾含量以T2最高。说明4月15日(T2)至4月20日(T3)移栽较有利于烟株的生长发育。
In order to verify the relationship between the transplanting period and the growth and development of flue-cured tobacco,the influence of different transplanting periods on the main growth characteristics of Guiyan 5 during flower bud differentiation stage were investigated.The results indicated that the start and the end of tobacco plant flower bud differentiation time was delayed accordingly along with the transplanting period postponed and the duration also shorted accordingly.The start time for flower bud differentiation was 9d-12d after resettling,while the end time was 5d-7d after budding,lasting for a total of 22d-25d.At the start of flower bud differentiation the main agronomic traits of tobacco plant are expressed best in T3,and the contents of nitrogen（N）,phosphorus（P） and potassium（K）,abbreviated as NPK,in stems and leaves were highest in T3.At the end of flower bud differentiation the main agronomic characters are expressed best in T2,and the contents of NPK in stems and leaves were highest in T2.The study showed that transplanting period of April 15（T2） to April 20（T3） is beneficial to the growth and development of tobacco plants.
