【摘要】 通过不同播种期试验，了解气候条件对烤烟品种K346生育特性的影响，探寻K346在龙岩市的适宜播种期。试验结果表明：随着播种期的推迟，苗床期相应延长，大田期则缩短，全生育期表现出缩短的趋势烟株有效叶片数、株高、节距和茎围存在显著的差异，有效叶片数、株高、节距表现为增加，茎围表现为减小。所以，K346在龙岩烟区以12月中旬左右播种，2月中旬左右移栽为宜。更多还原

【Abstract】 Different seeding time experiments were conducted to study the affection of climate condition on growing characteristics of K346 seeking the suitable seeding time of K346 in Longyan area． With the seeding－time＇s postponed seed bed stage was lengthened and field growth stage was shortened． The experiments showed that the effective leaf number plant height and internode were increased and stalk cricumference was decreased while the seed time was put off． The variance was significant． The suitable seed time of K346 is the middle ten days of Dec． in Longyan area．更多还原
