What is the best rootstock for grafting 10 seedlings?

Grafting propagation of seedlings is a commonly used method, which has the characteristics of rapid reproduction and excellent species character of flowers and trees. In order to achieve the desired effect of grafting, reasonable selection of rootstocks is an important part of whether the grafting is successful or not.

Here is a brief introduction to the selection of rootstocks for grafting of 10 kinds of seedlings:

1. Chimonanthus mume

Can choose dog fly plum (also known as Chimonanthus officinalis) as rootstock, its flowers are small, light color, perianth segments narrow and pointed, fragrance is not strong, is a semi-wild type of Chimonanthus, very strong resistance, mostly used as the rootstock of horticultural varieties. The method of cutting is often used for grafting in spring.

two。 Green peach

Can choose hairy peach, mountain peach as rootstock, using bud grafting or branch grafting method. Branch grafting takes place in spring and bud grafting in summer.

3. Osmanthus fragrans

Ligustrum lucidum, Ligustrum lucidum, Ligustrum lucidum and Ligustrum lucidum were selected as grafting rootstocks of sweet-scented osmanthus. Cutting and bud grafting should be carried out before sprouting in early spring, and bud grafting should be carried out in summer. 1-year-old strong branches and ears with full bud eyes were grafted on the rootstock.

4. Smile

Magnolia Magnolia and Michelia mollissima with a diameter of more than 0.8 cm can be selected as rootstocks. After the annual "Rain Water", choose sunny days to graft with splicing method.

5. Cherry blossom

Mountain cherry can be used as rootstock and grafted by cutting or bud grafting. Cutting and grafting should be carried out in spring and bud grafting in summer.

6. Ginkgo biloba

2-3-year-old sowing seedlings, cutting seedlings and root tiller seedlings can be selected as rootstocks. Rootstock requires strong growth, straight seedling stem and strong stress resistance. The height of rootstock varies according to the goal of cultivation.

For dense planting of early fruit, the grafting position is about 1 meter and the seedling height is about 1.5 meters.

For garden growers, the position is 1.5 to 2 meters and the seedling height is 2 to 2.5 meters.

For road greening, the position is about 2.5 meters and the seedling height is about 3 meters.

7. Magnolia

Magnolia, Magnolia or Michelia can be used as rootstocks. Grafting is usually used, usually from June to July, and splicing should be carried out in spring.

8. Yulan

A variety of Magnolia Magnolia or Magnolia officinalis seedlings are often selected as rootstocks. It can be grafted by means of relying grafting, bud grafting, branch grafting and so on. It usually takes place in early spring.

9. Fusang

Purple hibiscus is commonly used as rootstock. Cutting and grafting should be carried out in spring and bud grafting in summer.

10. Golden willow

Weeping willow with fast growth and strong stress resistance is selected as rootstock, and the varieties suitable for rootstock are fast-growing willow, golden willow and so on. When raising seedlings by cutting, the common willow used as rootstock should be closely planted according to the row spacing of 80 cm and the plant spacing of 40 cm. When the seedlings grow to 60 to 70 cm high, the plant spacing can reach 80 cm, so that the seedlings can reach the grafting standard of the same year, that is, the DBH of the rootstock is 3 cm and the height is more than 3 meters. The suitable time for grafting is from the end of February to the beginning of March. Because of the great disparity between the thickness of rootstock and scion segment, the grafting should be carried out by split grafting.
