Red Tip Photinia, scientific name Photinia × fraseri, is a hybrid species of the family Rosaceae and the genus Photinia. Red Tip Photinia is a small evergreen tree or shrub, with trees up to 5 m tall and shrubs up to 2 m tall. Red Tip Photinia is a street tree with a pole like a torch. Do a hedge, its shape lying like a dragon; Trim landscape, the shape can be varied, beautiful landscape effect.
Red Tip Photinia (Photinia × fraseri) is a small evergreen tree, up to 12 m tall, compact plant shape, leathery, long elliptic to lateral ovate-elliptic, serrated, new leaves bright red, complex cymbidium, midsummer to late summer white flowers. red tip Photinia berry is red. Leaves are simple, whorled, lanceolate to lanceolate, 6 -- 12 x 2.8 -- 4cm, bright red on new shoots and leaves, leathery on old leaves, dark green with a glossy surface, greenback, smooth and glabrous. Inflorescences of terminal corymbs panicles, 10 -- 18cm long. The new leaves of red tip photinia are red in spring, turn green in summer, and appear red in autumn, winter and spring. The frost is heavy and the color is thicker, and the color at low temperature is better. Foliar is waxy, peripheral irregular small serrated, the top branches of the four seasons leaf stem bright red such as a fire. Red Robin and red lips are two common varieties, of which the red Robin leaf color is dazzling, ornamental better. In spring and autumn, the new shoots and young leaves of red tip Photinia are bright and vibrant with long-lasting colors. During the summer heat, the leaves turn bright green, bringing a fresh and cool feeling to the hot summer days.
With the vigorous development of urban landscaping, Red Tip Photinia has been introduced and cultivated in Beijing, Tianjin, Shandong, Hebei, Shaanxi and other places.
In Tangquan Town, Nanjing City, the main business is a large number of Red Tip Photinia, which is one of the most cultivated seedling towns in East China.
Red Tip Photinia (Photinia × fraseri) is pleasant light, slightly shade, like warm and humid climate, drought tolerance barren, not water wet.
Red Tip Photinia (Photinia × fraseri) likes a warm, humid, sunny environment. Red Tip Photinia cold resistance is strong can withstand the lowest temperature -18℃. Red Tip Photinia likes strong light, also have very strong shade tolerance ability, suitable for all kinds of medium fertilizer soil quality. Tolerant soil barren, there is a certain tolerance to salt and alkali and drought ability, not resistant to moisture. Red Tip Photinia is fast-growing, strong germination, resistant to pruning, easy to transplant, and easy to form.
After entering the winter dormant period, the following four measures should be taken to care for Red Tip Photinia in landscape engineering applications.
1. Root injury permafrost of antifreeze soil is easy to cause physiological drought and death of plants. For Red Tip Photinia planted in regions with permafrost in winter, especially those planted in the same year, the soil should be frost proof and the root system should be protected. Ground cover is usually applied half a month before the formation of the permafrost to maintain soil temperature.
2. Disease and insect pest control is mainly to clean up the overwintering hosts of diseases and insects such as diseased branches, insect branches and dead branches, so as to reduce the diseases and insect pests in the coming year.
3. Application of winter fertilizer in order to ensure the strong growth of spring shoots and the ornamental effect, apply winter fertilizer once from December of the current year to the middle of January of the next year in combination with loose soil. Fertilizer with nitrogen content higher compound fertilizer is appropriate, the dosage is about 40 grams per square meter.
Red Tip Photinia sprout early, usually before the end of February. In order to improve the consistency and compactness of spring new shoot germination, to achieve the best effect of viewing, according to the use requirements of different products in January to carry out the corresponding light pruning. Since Red Tip Photinia is used in a wide range of areas, the corresponding winter maintenance time and measures should be based on the local conditions to achieve the best results.
Red Tip Photinia (Photinia × fraseri) has a strong resistance to Photinia and no destructive diseases or pests were found. Common red tip photinia diseases and insect pests include blight, cataplexy, leaf spot, gray fungus, leaf spot, anthrax and scale insects, etc. These infectious diseases often cause large-scale death of Red Tip Photinia in a short period of time and bring serious losses to seedling farmers. Nursery of Sichuan county of Henan province quotes expert point of view of the nursery to introduce a few kinds of comprehensive prevention and control measures to you, in order to provide friends of nursery farmers need when reference.
Gray mold of Red Tip Photinia can be prevented by 50% carbendazim 1000 times liquid spray and can be prevented by 50% diazepine 800 times liquid spray during onset. Leaf spot disease can be controlled by 60% carbendazim 300-400 times solution or obtain 300-400 times solution. Scale insects of Red Tip Photinia can be sprayed with 200 times of diethanate emulsion or 800-1000 times of liquid spray prevention and control. The soil silkworm prevention and control should be carried out before planting, the ground should be properly deep plowing, and sprinkle phosphorus-containing insecticides such as soil insects must be killed. In case of silkworm damage after planting, remedial treatment should be carried out in time, otherwise the spread will be very harmful, especially for the Red Tip Photinia in the seedling stage, which may cause a large area of death.
Growth speed and strong germination, resistance to pruning, Red Tip Photinia (Photinia × fraseri) can be cultivated into different tree shapes according to the needs of the garden, widely used in landscaping. One to two years old Red Tip Photinia can be pruned into dwarf shrubs, used as ground cover in green Spaces, or combined with other color-leaved plants to form various patterns. It can also be cultivated into small trees that are not obvious and clumps, and planted into large hedges or curtain walls. Red Tip Photinia can be applied in the green belts of residential areas, factory areas, streets or highways. When the hedges or curtain walls are red, they are very gorgeous and full of vitality. Red Tip Photinia can also be grown as a solitary, spherical canopy tree that can be planted alone in green Spaces, used as a sidewalk tree, or potted for porches and indoors.
Red Tip Photinia has been widely used in foreign countries, especially in Europe, America and Japan, and is known as the "King of Red Leafed and Green Hedgerows". However, Red Tip Photinia is a newly introduced and developed tree species in China in recent years. At present, it is in the seedling breeding stage, and only a few seedlings are supplied to the market. There are no large-scale seedlings for garden application. Far from meeting the needs of nursery and garden engineering applications. Therefore, the market prospect of the tree species is broad and the development potential is huge.
