Embodiment 1

[0023] (1) Cultivate rose seedlings with well-developed root system, intact mother leaves of cuttings, and 2 cm long twigs as usual, during which water management is carried out as usual to keep the soil moist, and shading with a shading rate of 50% is used in high temperature seasons Shade with a net to prevent necrosis of shoots until the shoots of rose seedlings grow to 10 cm, and the upper leaves of the shoots unfold to become first-class branches;

[0024] (2) Cut off and discard the 5 leaflets at the upper end of the first-level branch in step (1), and let the plant continue to grow until new shoots germinate from the pruned part to become a second-level branch;

[0025] (3) When the secondary branch of step (2) grows to 30 cm and flower buds appear, cut off and discard the 3 leaflets from the upper end of the secondary branch together with the flower buds, so as to inhibit the production of flower branches and reduce soil nutrients consumption, and then let the secondar...

Embodiment 2

[0029] (1) Cultivate rose seedlings with well-developed root system, intact mother leaves of cuttings, and 4 cm long twigs as usual, during which water management is carried out as usual to keep the soil moist, and shading with a shading rate of 70% is used in high temperature seasons. Shade with a net to prevent necrosis of the shoots until the tender shoots of rose seedlings grow to 15 cm, and the upper leaves of the tender shoots unfold to become first-class branches;

[0030] (2) Cut off and discard the 5 leaflets at the upper end of the first-level branch in step (1), and let the plant continue to grow until new shoots germinate from the pruned part to become a second-level branch;

[0031] (3) When the secondary branch of step (2) grows to 45 cm and flower buds appear, cut off and discard the 3 leaflets from the upper end of the secondary branch together with the flower buds to prevent it from producing flower branches and reduce soil nutrients consumption, and then let ...

Embodiment 3

[0035] (1) Cultivate rose seedlings with well-developed root system, intact mother leaves of cuttings, and 3 cm long twigs as usual, during which water management is carried out as usual to keep the soil moist, and shading with a shading rate of 60% is used in high temperature seasons Shade with a net to prevent necrosis of the shoots until the tender shoots of rose seedlings grow to 12 cm, and the upper leaves of the tender shoots unfold to become first-class branches;

[0036] (2) Cut off and discard the 5 leaflets at the upper end of the first-level branch in step (1), and let the plant continue to grow until new shoots germinate from the pruned part to become a second-level branch;

[0037] (3) When the secondary branch of step (2) grows to 40 cm and flower buds appear, cut off and discard the 3 leaflets from the upper end of the secondary branch together with the flower buds, so as to inhibit the production of flower branches and reduce soil nutrients consumption, and the...

Abstract

The invention provides a method for culturing a vegetative shoot of rosa hybrida. The method includes: cultivating rosa hybrida cutting seeding, growing and trimming a first-class branch, enabling a second-class branch to sprout on the first-class branch trimming position, growing and trimming the second-class branch, twisting the first-class branch portion 3-4cm away from a base portion when the second-class branch is matured to damage the inside of the branch in a mode that the cortex cannot be damaged and the branch cannot be broken, enabling the twisted portion of the branch to be bent and drop naturally due to the fact that no supporting exists, performing medicine prevention on the twisted position, enabling the vegetations to grow until a sprout grows on the base portion of the first-class branch and obtaining the vegetative shoot. By means of the method for culturing the vegetative shoot of rosa hybrida, the sprouting time of rosa hybrida branches is shortened by utilizing the sprouting characteristics of the rosa hybrida branches, the problem of difficult pest management and high cost caused by multiple layering and branch overlapping can be solved, continuous photosynthetic capacity can be provided to growing of the branches, and quality and yield of the rosa hybrida can be improved.

Description

technical field [0001] The invention relates to a method for cultivating vegetative branches of cut roses at seedling stage, and belongs to the technical field of standardized planting of plants. Background technique [0002] Rose ( Rosa hybrid ) is a woody plant of the genus Rosa in the Rosaceae family and is the largest cut flower in the world. The production of fresh-cut roses has gradually evolved from open field cultivation to intensive and efficient production in facilities. On the basis of ensuring product quality, high yield is the most important goal pursued by producers all over the world. [0003] Broken branch cultivation is the most ideal cultivation mode obtained through many years of exploration and summary of cut flower production technology in various countries in the world, and it has played an important role in improving the yield and quality of cut flower rose. According to the functions and uses of the branches of cut rose plants, they are divided int...
