Embodiment 1

[0025] (1) Choose the stock from the end of February to the beginning of May each year, choose a 1-year-old tree with a ground diameter of 2 cm and an upright young tree of Photinia dushan as the stock;

[0026] (2) cut off the rootstock at a height of 0.5m from the ground above the rootstock, and keep 4-8 blades below the rootstock section for support;

[0027] (3) Opening cuts from top to bottom with a knife at the appropriate position of the above-mentioned rootstock section to form a 1cm in length and a 2cm incision for subsequent use;

[0028] (4) cut the scion and choose the well-grown semi-lignified branch of Photinia mahogany as the scion, cut the segment with 2-3 full buds as the scion, and cut one side of the scion bottom into a large inclined plane of 2cm, described The large slope is on the same side as the terminal bud, and the other side is cut with a 1cm long small cut surface, and the spikes are picked as they are picked, and they are properly shaded;

Description

technical field [0001] The invention relates to the technical field of plant breeding, in particular to the technical field of a grafting method of Photinia fruticosa. Background technique [0002] Red leaf Photinia (scientific name: Photiniaxfraseri) is an evergreen shrub or small tree of the genus Photinia in the Rosaceae family. It is an evergreen small tree with a plant height of 4-6 meters. Green, red in autumn, winter and spring, the color of frost is thicker, and the color of low temperature is better. This variety was introduced into my country from the Netherlands in 1995, and has been cultivated in East China, Central South and Southwest China. Its new shoots and young leaves are bright red, bright and lasting in color, and the mature leaves are dark green, shiny and full of vitality. Therefore, it has become the most fashionable series of red-leaf tree species in the global greening tree species. It has been widely used in Europe, America and Japan, and is known ...
