AI Technical Summary

Problems solved by technology

The number of ramets is very small, which is far from meeting the needs
Grafting and propagation is the most commonly used method in modern horticulture, but rootstocks need to be cultivated first, many scions are required, operation is inconvenient, and the conditions and technical requirements for tissue culture are high, which is difficult for ordinary garden enterprises and farmers to achieve.

Embodiment 1

[0023] Grafting papaya and crabapple with the roots of Vitex chinensis as rootstock:

[0024] 1. When Vitex japonica seedlings come out of the nursery at the end of autumn, for the seedling roots left in the soil or trimmed from the seedlings, choose annual roots with a diameter of more than 0.3 cm, and cut them into root segments of 8-10 cm. There are 1-3 fibrous roots, which are cut off and buried in wet sand for later use.

[0025] 2. Choose papaya and crabapple trees that grow robustly, are free from diseases and insect pests, have full and healthy buds, and have annual branches with a diameter of about 0.3-0.5cm.

[0026] 3. Use scissors to cut off the thorns or residual leaves on the scion, cut two knives at the relative position below the bud point, and cut it into a wedge-shaped sliced ​​surface. The knife should be very clean and neat, and the two cut surfaces should be equal. Keep 1-2 buds for each scion Point, cut the top of the scion into a flat mouth.

[0033] Grafting Xifu crabapple with the roots of Vitex chinensis as rootstock:

[0034] 1. When Vitex japonica seedlings come out of the nursery at the end of autumn, for the seedling roots left in the soil or trimmed from the seedlings, choose annual roots with a diameter of more than 0.3 cm, and cut them into root segments of 8-10 cm. There are 1-3 fibrous roots, which are cut off and buried in wet sand for later use.

[0035] 2. Choose Xifu crabapple trees that grow robustly, have no pests and diseases, have full and healthy buds, and have annual branches with a diameter of about 0.3-0.5cm.

[0036] 3. Use scissors to cut off the thorns or residual leaves on the scion, cut two knives at the relative position below the bud point, and cut it into a wedge-shaped sliced ​​surface. The knife should be very clean and neat, and the two cut surfaces should be equal. Keep 1-2 buds for each scion Point, and cut the top of the scion flat.

[0037] 4. Cut off the cut scion, soak in 5...

Abstract

The invention relates to the technical field of human cloning seedling of plants, in particular to a root-grafting seedling method for Chinese flowering crabapple. Problems that the Chinese flowering crabapple is prone to generation of variation and losing favorable properties due to adoption of sowing and seedling, rooting rate in raising seedlings by cutting is low, more materials are needed, the shape of a seed tree is damaged due to too much trimming, ornamental value is lowered, stock cultivation needed in seedling by grafting is labor-consuming and time-consuming, reproduction is slow, coefficient is low, technical difficulty in group seedling is high, cost is high and the like are effectively solved.

Description

technical field [0001] The invention relates to the technical field of artificial vegetative propagation and seedling cultivation of plants, in particular to a root-grafting method of crabapple. Background technique [0002] Begonia is a deciduous shrub or small tree of the Rosaceae apple genus, many of which are famous ornamental plants, such as: Xifu Begonia, Suisi Begonia, Iron Stem Begonia and Papaya Begonia, commonly known as "Four Begonias", which are famous ornamental tree species in China. It is an important temperate flowering tree and is commonly cultivated in various places. Begonias are elegant and unrestrained flowers blooming like brocades. Since ancient times, they have been a famous flower appreciated by both refined and popular people. In royal gardens, it is often planted together with magnolia, peony, and sweet-scented osmanthus to form the artistic conception of "Jade Tang is rich and noble". In addition, crabapple flowers have strong resistance to sulf...
