Problems solved by technology

[0003] In related technologies, due to the nature of the plant itself, the cold resistance of flue-cured tobacco is relatively poor.
During the growth process of flue-cured tobacco, it is inevitable that it will suffer from chilling weather (close to 0°C or even lower temperature). When the flue-cured tobacco is frozen, it will cause chilling damage to the tobacco seedlings, early flowering, reduced yield, and reduced quality.

Embodiment 1

[0015] An embodiment of the present invention provides a method for cultivating improved flue-cured tobacco plants, including the following steps, please refer to figure 1 :

[0016] Step 101: Cultivate flue-cured tobacco seedlings to obtain scions;

[0017] Step 102: Cultivate rapeseed seedlings to obtain rootstocks;

[0018] Step 103: grafting the scion onto the rootstock to obtain a grafted plant;

[0019] Step 104: Cultivate the grafted plants to obtain improved flue-cured tobacco plants.

[0020] The method for cultivating improved flue-cured tobacco plants provided in the embodiments of the present invention can breed improved flue-cured tobacco plants. Specifically, since the improved flue-cured tobacco plants are grafted with rapeseed as the stock and flue-cured tobacco as the scion; therefore, the improved flue-cured tobacco plants It combines the excellent characteristics of flue-cured tobacco and rapeseed, and rapeseed has good drought resistance; it also has goo...

Embodiment 2

[0024] The cultivation method of the improved flue-cured tobacco plant of the present embodiment comprises the following steps, please refer to figure 2 :

[0025] Step 201: Cultivate flue-cured tobacco seedlings so that the stem height of the tobacco seedlings is greater than 5 cm and the stem circumference is greater than 0.6 cm. Cut off the roots of the tobacco seedlings, retain the true leaves and axillary buds, and obtain 3-5 cm long stems. Scion;

[0026] In step 201, in order to ensure the quality of the scion, it is preferable to make the tobacco seedlings grow until the height of the stem is greater than 5 cm and the circumference of the stem is greater than 0.6 cm. cm, the tobacco seedlings are in a period of rapid growth, which can increase the survival rate of grafting. In addition, in the process of obtaining scions, tobacco seedling plants that grow vigorously and are free from diseases and insect pests should be selected.

[0027] It should be noted that in ...

Abstract

The invention relates to the field of crop growing, and particularly relates to a cultivation method of an improved tobacco plant. The cultivation method comprises the following steps: cultivating a tobacco seedling to obtain a scion; cultivating an oilseed rape seedling to obtain a stock; grafting the scion to the stock to obtain a grafted plant; and cultivating the grafted plant to obtain the improved tobacco plant. According to the improved tobacco plant cultivated by adopting the cultivation method of the improved tobacco plant, provided by the invention, the defect that the output of tobaccos is reduced after the tobaccos are frozen in the prior art is overcome to a certain degree.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a cultivation method for improving flue-cured tobacco plants. Background technique [0002] Flue-cured tobacco is an annual herb belonging to the family Solanaceae. The plant is covered with glandular hairs, and the finished plant height can reach 1 meter. The petiole is wing-shaped, the calyx is cylindrical, and the corolla is funnel-shaped. Originally produced in South America, it is now cultivated all over the world and is an important raw material in the tobacco industry. [0003] In related technologies, due to the nature of the plant itself, the cold resistance of flue-cured tobacco is relatively poor. During the growth process of flue-cured tobacco, it is inevitable that it will suffer from chilling weather (close to 0 ℃, or even lower temperature). When flue-cured tobacco is frozen, it will cause chilling damage to tobacco seedlings, early flowering, reduced yield and lo...
