[0002] Tobacco is a plant of the genus Nicotiana in the Solanaceae family. It is an annual or limited perennial herb with glandular hairs all over. The root is thick. The stem is 0.7-2 meters high, with a slightly lignified base. The leaves are oblong-lanceolate, lanceolate, oblong or ovate, with a gradually pointed apex and a gradually narrowed base until the stem becomes ear-shaped and semi-amplexicaulous. The inflorescence is terminal, conical, and multi-flowered. The pedicel is 5-20 mm long and blooms and bears fruit in summer and autumn. Tobacco needs to be transplanted. Transplantation can achieve high-quality and efficient cultivation of tobacco and obtain good economic benefits. Tobacco transplantation is directly related to the growth of tobacco and its later harvest.
