Embodiment 1

[0028] A method for grafting petunias with fake tobacco leaves and cultivating dendritic petunias, comprising the following steps:

[0029] (1) Rootstock cultivation: The seedlings of fake tobacco leaves are cultivated by sowing, and then cultivated in the ground for 2 years. The fake tobacco leaves with a straight trunk, a ground diameter of 3 cm, and a tree height of 2 meters are selected as rootstocks, and the rootstocks are topped and trimmed to promote division branches, and the branches below 1 meter of the main trunk are not retained, forming an umbrella-shaped full crown with a crown width of 0.8 meters;

[0030] (2) Cultivation of rootstock grafted branches: Cut off branches at the secondary or tertiary branches of the rootstock, keep the branch length 10 cm, and control the height of the rootstock below 2 meters; after the new buds germinate to 3 cm, perform bud removal treatment, Keep 2 buds on each branch for cultivation to obtain a thick grafted branch; when the g...

Embodiment 2

[0039] A method for grafting petunias with fake tobacco leaves and cultivating dendritic petunias, comprising the following steps:

[0040] (1) Rootstock cultivation: The seedlings of fake tobacco leaves are cultivated by sowing, and then planted in the ground for 3 years. The fake tobacco leaves with a straight trunk, a ground diameter of 4 cm, and a tree height of 2.5 meters are selected as rootstocks. The rootstocks are topped and trimmed to promote division branches, and the branches below 1 meter of the main trunk are not retained, forming an umbrella-shaped full crown with a crown width of 1 meter;

[0041] (2) Cultivation of rootstock grafted branches: Cut off branches at the secondary or tertiary branches of the rootstock, keep the branch length of 12 cm, and control the height of the rootstock below 2 meters; after the new buds germinate to 4 cm, perform bud removal treatment, Keep 3 buds on each branch for cultivation to obtain a thick grafted branch; when the grafte...

Embodiment 3

[0050] A method for grafting petunias with fake tobacco leaves and cultivating dendritic petunias, comprising the following steps:

[0051] (1) Rootstock cultivation: The seedlings of fake tobacco leaves are raised by sowing, and then they are cultivated in the ground for 2 years. The fake tobacco leaves with a straight trunk, a ground diameter of 5 cm, and a tree height of 2.3 meters are selected as rootstocks, and the rootstocks are topped and trimmed to promote division branches, and the branches below 1 meter of the main trunk are not retained, forming an umbrella-shaped full crown with a crown width of 1.5 meters;

[0052] (2) Cultivation of rootstock grafted branches: Cut off branches at the secondary or tertiary branches of the rootstock, keep the branch length at 15 cm, and control the height of the rootstock at less than 2 meters; after the new buds germinate to 5 cm, wipe the buds. Keep 3 buds on each branch for cultivation to obtain a thick grafted branch; when the ...

Abstract

The invention discloses a method for grafting petunia hybrida and Solanum erianthum to cultivate tree-shaped petunia hybrida. The method comprises the steps of stock cultivation, stock grafting branch cultivation, scion preparation, grafting implementation, scion management after grafting, stock management after grafting, grafting film removal, petunia hybrida scion reinforcement and shaping, flowering management and the like. According to the method, the Solanum erianthum is taken as the stock, a stock twig side grafting method is adopted, the scions and the stock are subjected to different treatments, perennial creeping petunia hybrida is grafted to 2-meter-high branches of small-arbor-shaped Solanum erianthum, and a tree-shaped petunia hybrida plant is obtained. According to the method, the Solanum erianthum and the perennial petunia hybrida are successfully grafted, the healing property is good, the Solanum erianthum and the perennial petunia hybrida grow harmoniously, the rejection phenomenon does not exist, and the problem that perennial herbaceous plants and small arbor plants of different genera of solanaceae cannot be grafted to survive and coexist and grow synergistically for a long time is solved.

Description

technical field [0001] The invention belongs to the technical field of plant grafting, and in particular relates to a method for grafting petunia and fake tobacco leaves to cultivate dendritic petunia. Background technique [0002] Fake tobacco leaves belong to the genus Solanaceae. Small tree, 1.5-10 meters high, leaves 10-23 cm long, 6-15 cm wide, branches with cambium and xylem. The production areas include Sichuan, Guizhou, Yunnan, Guangxi, Guangdong, Fujian and Taiwan provinces in China, and are widely distributed in tropical Asia, Oceania and South America. Fake tobacco leaves have the advantages of tall plants, fast growth, resistance to barrenness, strong adaptability, heat resistance and drought resistance. [0003] Petunia is a common name for Petunia, which belongs to the genus Petunia in the family Solanaceae. It is a perennial herb, often cultivated as one or two years, with a height of 20-45 cm, and the stems grow on the ground. The flowering period is from ...
