Embodiment Construction

[0011] The arborization pruning management method of Photinia fragrans in this embodiment includes: in July to August, take healthy Photinia fragrans for 4 to 6 years as the mother tree, cut twigs with a length of 10 to 16 cm and culture them in containers in the culture medium, and plant them in the next spring. Take out the twigs, transplant them to the seedbed and grow them for 16-18 months. Cut off the stems on the ground and go out to germinate tillers. When the main trunk reaches 1.8m, cut back the lateral branches below 1.5m. 3cm, keep it to 3~5cm, and then transplant it to expand the row spacing, pick the heart in the spring of the third year, and dry it to get arborization of Photinia fruticosa.

[0012] The container culture is kept at a temperature of 25-27°C and a humidity of 80-85%, and phoxim is used for soil disinfection management.

[0013] The substrate selected for container culture includes yellow core soil, vermiculite, and perlite mixed in a mass ratio of ...

Abstract

The invention discloses an arbor trimming management method for photinia fraseri. The method comprises the following steps that in July to August, healthy four-six-year photinia fraseri is used as mother trees, epicormic branches with the length being 10 to 16cm are cut and are cultured in a culture medium, the epicormic branches are taken out in spring of a next year, after the epicormic branches are transplanted in a seedling bed to growth for 16 to 18 months, the flat ground trunk cutting is carried out, sprout tillers are removed, side branches below 1.5m are cut again when the main trunk reaches 1.8m, once trimming is carried out in autumn, the lateral branches longer than 3cm are maintained for 3 to 5cm, then, the transplanting is carried out, the strain line distance is enlarged, pinching is carried out in spring of a third year, stem determination is carried out, and the arbor photinia fraseri is obtained. The invention provides the novel high-stem arbor ornamental photinia fraseri. Because the sprout tiller performance of the photinia fraseri is stronger, in the method, the lower side branches are trimmed so that the height increase and the arbor change are realized, the growth conditions of branches and leaves at the upper part are good, the upper end of the plant is red and vivid, the lower end of the plant is slender, and a unique effect is realized. The method provided by the invention has the advantages that the implementation is simple and efficient, and the method is suitable of being popularized in various ornamental gardens or scenic spots.

Description

technical field [0001] The invention relates to a plant cultivation and management method, in particular to an arborization method of Photinia fruticosa. Background technique [0002] Red leaf Photinia (scientific name: Photinia serrulata) is the collective name for hybrids of the genus Photinia in the family Rosaceae. It is an evergreen shrub or small tree, long oval to obovate-lanceolate, with red leaves in spring, green in summer, red in autumn, winter and spring, and heavy frost. The color is thicker, and the color of the lower temperature is better. Photinia has a fast growth rate and strong sprouting ability, so its pruning and management are particularly important. If the Red River heather is allowed to grow, the tree will have many branches, the crown will be large and uneven, and the ornamental value will be greatly reduced. [0003] At present, Photinia fruticosa is usually pruned early, and it is pruned into a spherical shrub. However, this pruning method nee...
