In Liaoning, Anhui, Zhejiang, Jiangxi, northern Fujian, Guangxi. 1 600-2 was born in an altitude of 000 meters of the mountain. Korea and Japan are also distributed.
Wood system tools, aromatic oil can be extracted from flowers. Beautiful flowers, with long pedicel, flapping in the wind, is famous for its ornamental plant. Take medicine, can extract.
Leaves broadly obovate or oval. Spend Xie Tongfang before or after the leaf spends, tepals 9, outer 2 round in pink, white, purple red silk. Flowers with long stems of wind fluttering like The heavenly maids scatter blossoms. Located in the northeast and East China and Shandong, Hunan, Guizhou, Guangxi, was born at 300-2000m above sea level, moist forest and rock cracks in the valley. The Korean Peninsula, Japan also has distribution. Three countries to protect endangered species.

Oyama Magnolia cultivation techniques

Multi layering, plant breeding. Sometimes the sowing. Ramet, spring and autumn can be dug up, branches dense plant were planted, and root pruning and cutting short branches. The layering, one or two year old shoots in early spring, the available heap of indigenous or buried law reproduction. Sowing seed in winter, September, sand, the following spring sowing, germination 20-30 days after sowing. Cultivation and management is simple, pay attention to drought and waterlogging, timely fertilization. Transplantation can be carried out in the autumn or early spring before flowering, seedlings with mud Zhanzi seedlings with soil ball must be. Flowering before and after fertilization 1 times with phosphorus and potassium. High temperature in summer and autumn drought season, preserving soil moisture. After the flower bud and shoot before, should cut off the branches, branches and cutting short leggy branches.
Mulan happy light, a little shade. Hi warm and humid climate, can also be cold. Likes fertile, moist and well drained sandy soil, drought resistant, anti alkali, alkaline earth and clay in the dry, poor growth. Roots fleshy, fear of flooding, wound healing, transplanting survival is not easy. Strong tillering. Mulan by division, layering, cutting propagation.
Magnolia transplanting in spring smallpox Before or after the fall leaves, small seedlings seedlings with soil ball to old territory. Magnolia like fertilizer, every year 10 ~ November is added to the pile of rotten manure as a fertilizer during flower bud sprouting after topdressing, 2 ~ 3 times of available nitrogen fertilizer, dry rhizosphere coverage and moderate watering. The next year is expected to andflourishing.
Magnolia trees to the tree must be in bud and tiller, pruning. Magnolia root rot, red spider, etc. should be timely prevention and treatment of borers.
Curing light is cold resistant, but not drought. Require fertile sandy soil, not alkali resistant. Fear of flooding. Magnolia prefers moist semi shade climate, like fertilizer, has the good permeability of soil in winter digging, organic fertilizer, such as meal, cake. Magnolia strong resistance to cold, but avoid drought and waterlogging, usually to ensure water supply, often to increase air spraying to avoid damp toxin, yellow leaves.
Pest control
Pittosporum icerya major harm plants, the host is very wide, common hazards. Female adults and larvae often concentrated in bud, leaf, branch and stem sap sucking, serious when can cause all the branches, yellow leaves, shoots, leaves, branches short, deformation, or even the death of the whole plant, and easy to induce Sooty Blotch, make leaf black, impeding photosynthesis, thereby reducing the potential impact of the tree. Ornamental value. Secretion of honeydew one or two instar nymphs suck juice, which is mainly caused by coal pollution disease. The female adult mature after fixed harm, no transfer.
Control method:
1, silvicultural measures: remove pests and insect plant pruning branches, to bring out the fields were burned.
2, biological control: protection of Australia, introducing the ladybug, red ladybug.
3, drug prevention: dormant spraying pop 1-3 degrees LSSS; nymphs hatching period available 40% Omethoate 1000 times 10% pyrine WP 1500 times liquid; adults occur when using 800 - scale mad kill 1000 times or 40% supracid EC 1500 times liquid spray, spraying when adding proper amount of diesel oil at the same time can increase the permeability of the required solution must spray penetration spray evenly. Kill crazy scale to scale effects.
