为了探明陕南烟区主栽品种K326的适宜移栽期，在陕南旬阳县开展了烤烟移栽期试验研究。结果表明，随移栽期推后，各主要生育期均向后推迟，大田生育期缩短；旺长期、平顶期和成熟期烟叶氮钾、叶绿素和碳水化合物含量及净光合速率均先升高后降低，产量、均价、产值和中上等烟比率均表现出同一趋势。综合分析，依据当地气候条件特点，以旬阳试验点为代表的相同海拔区域，烤烟K326最适宜移栽期为5月10日；确定适宜移栽期可改善烟叶氮钾营养，提高光合性能，有利于干物质累积，从而提高烟叶的产量和品质。

To elucidate the best transplanting data of main flue-cured tobacco cultivar K326 in tobacco-growing regions of southern Shaanxi province, an experiment evaluating transplanting date was carried out in Xunyang county. The results showed that with postponement of transplanting date of flue-cured tobacco, all main growth dates were put off; field growth period after transplant became shorter. In addition, contents of nitrogen, potassium, chlorophyll and carbohydrate as well as net photosynthesis rate (Pn) of tobacco leaves at key three growth stages i.e. vigorous growing. topping and mature stages were enhanced firstly and then declines. Yield, average price, output value and percentage of medium and superior tobacco leaves showed the similar laws as the above parameters. Based on comprehensive analysis, May 10 was the best appropriate transplanting date of K326 in Xunyang as a representative location of the same altitude area according to the climatic conditions of this area. To determining the best appropriate transplanting date can improve nitrogen and potassium nutrition and increase photosynthetic efficiency for dry matter accumulation resulting in better yield and quality of flue-cured tobacco leaves.
