Embodiment

[0019] In a flue-cured tobacco base in Mile County, Yunnan Province, 800 flue-cured tobacco Cuibi No. 1 varieties and oriental tobacco SAM varieties were planted, and the growth characteristics, stress resistance, disease resistance and tobacco leaf yield and quality of the grafted plants were compared.

[0020] The specific operation steps are as follows:

[0021] 1 Select the rootstock and scion: choose the flue-cured tobacco Cuibi No. 1 variety as the rootstock, with a stem height of 5-7cm, a stem circumference of 0.5-1cm, full leaf buds, and no pests and diseases; choose the oriental tobacco SAM variety, with a stem height of 5-7cm and a stem circumference of about 0.5cm , The part with strong buds in the middle is cut into 5-6 cm long for scion, 2-3 buds should be left in each ear, the leaf buds are full, and there is no damage to the tobacco seedlings by diseases and insect pests.

[0022] 2 Grafting time: The grafting time is selected to be carried out in the middle and...

Abstract

The invention discloses a method for improving an aromatic tobacco variety SAM (Samsun). The method comprises the following steps of: on the basis of selecting flue-cured tobacco CB-1 as understock and a seedling of the aromatic tobacco variety SAM as scion, grafting at the first ten-day period of April by adopting a cleft grafting method, i.e. vertically cutting the understock to reach the depth of 1-1.5cm from the middle of a stem, and inserting the scion into the cut of the understock, wherein an axillary bud with a growing point is selected as the scion; and after grafting is successful, transplanting plants into a large field. According to the method, a grafting culture technical method for different aromatic tobacco varieties and flue-cured tobacco varieties is achieved for the first time, The gene seepage and exchange of different varieties can be artificially promoted, and a new tobacco plant variety can be created; and the new plant variety has self characteristics, also has the unique quality characteristic of the flue-cured tobacco CB-1, and has the advantages that the fragrance quality is improved, the harmony among the internal chemical compositions of tobacco is increased, and the stress resistance and the disease resistance are improved.
