Problems solved by technology

However, the uniformity of seedlings propagated by cuttings is different. Due to the influence of geographical conditions and soil factors, it is difficult to produce standard seedlings with straight stems; air pressure and ground pressure are commonly used for layering. Although the survival rate is high, the reproduction coefficient is very low; therefore To a certain extent, the development of

Embodiment 1

[0044] Adopt 1.6-meter sweet-scented osmanthus tree as the rootstock tree, the planting row spacing and column spacing of the rootstock tree are 1 meter × 1 meter, and the branches of osmanthus osmanthus with pearl colorful leaves are used as spikes, and the rootstock tree is cut and grafted on the main branch in the upper part of the rootstock tree. The specific steps as follows:

[0045] A. Rootstock tree treatment: remove all branches below 1.6 meters from the trunk of the sweet-scented osmanthus tree with branch shears or hand saws, and keep the thickness of more than 2 cm in each of the four directions of east, south, west, and north for rootstock trees above 1.6 meters 2 branches are used as rootstock branches for grafting, and all the other twigs and densely distributed branches are removed with branch shears;

[0046] B, rootstock branch processing: truncate branch at the 50 centimeters place of rootstock tree main trunk at rootstock branch, cut off from rootstock bran...

Embodiment 2

[0056] Osmanthus fragrans with a main pole diameter of 10 cm is used as the rootstock tree, and the planting row and row spacing of the rootstock tree is 4 meters × 4 meters. The branches of the osmanthus osmanthus with pearl colorful leaves are used as spikes, and the rootstock tree is cut and grafted on the main branch of the middle and upper part of the rootstock tree. ,Specific steps are as follows:

[0057] A. Rootstock tree treatment: Use branch shears or hand saws to remove all branches below 1.6 meters from the trunk of the osmanthus tree, and keep the thickness of more than 2 cm in each of the four directions of east, south, west, and north for rootstock trees above 1.8 meters. 4 branches are used as rootstock branches for grafting, and all the other twigs and densely distributed branches are removed with branch shears;

[0058] B, rootstock branch processing: truncate branch at the 52 centimeters place of rootstock tree main trunk at rootstock branch, cut from stock ...

Embodiment 3

[0068] Adopt 2-meter sweet-scented osmanthus tree as the rootstock tree, the planting row spacing and column spacing of the rootstock tree are 4 meters × 4 meters, and the branches of the osmanthus fragrans with pearl colorful leaves are used as spikes, and the rootstock tree is cut and grafted on the main branch in the upper part of the rootstock tree. The specific steps as follows:

[0069] A, rootstock tree treatment: remove all branches below 2 meters of the main trunk of the sweet-scented osmanthus tree with branch shears or hand saws, and keep the thickness of more than 2 centimeters in each of the four directions of east, south, west, and north for rootstock trees above 2 meters 5 branches are used as rootstock branches for grafting, and all the other twigs and densely distributed branches are removed with branch shears;

[0070] B, rootstock branch processing: truncate branch at the 55 centimeters place of rootstock tree main trunk at rootstock branch, cut from the sto...

Abstract

The invention discloses a standardized cultivation method for colorful sweet-scented osmanthus. The standardized cultivation method is characterized in that osmanthus trees which are 1.6-2 meters highare taken as root stocks and colorful sweet-scented osmanthus branches are used as scions and are subjected to cut-grafting on the upper main branches of the root stocks. Nursery stocks of the same plant type can be cultured by selecting the root stocks so that the grafted plants can be subjected to standardized production. Since the scions are mature when being grafted and the root stocks have strong root systems capable of absorbing enough nutrients, the grafted plants can grow rapidly with accumulation of rich nutrients; further, the grafted seedlings are stronger than general seedlings orcutting seedlings, blooming is advanced, breeding season is shortened, and seedling emergence rate is high. By application of the method, top grafting and transplanting is achieved, the grafting survival rate is up to 90% or higher than 90%, the grafted plants bloom the second year. Therefore, the method has extremely broad application prospect.

Description

technical field [0001] The invention relates to a cultivation method, in particular to a standardized cultivation method for pearl cassia osmanthus. Background technique [0002] Pearl color leaf osmanthus is a variant variety of golden osmanthus. It is a wonderful flower of the variant variety. As a new variety of osmanthus, its leaf color changes throughout the year and is splendid. Turn golden yellow to white. Then from the central main vein, it gradually changes to green on both sides. Until the dark green, under the condition of suitable climate, there are buds emerging all the year round, so the whole bead plant is colorful and colorful from top to bottom. It is a rare new variety that is precious and rare in the middle class of the sweet-scented osmanthus family. It has extremely broad application prospects. The propagation of existing pearl cayenne osmanthus generally adopts methods such as cuttage, layering and grafting. However, the uniformity of seedlings pro...
