Osmanthus tree, Osmanthus fragrans, Oleaceae (Oleaceae) Olea, are evergreen trees, up to 15 meters, solid material, fine texture, in acidic soil or calcareous soil can grow well. Osmanthus tree trees are elegant, blue green leaves, evergreen fragrance, pleasant, neutral tree, sapling resistant shade, middle-aged hi light. Sweet scented osmanthus tree is a very good garden trees and tree species.
Osmanthus tree cultivation techniques, the following information is for reference only
Seed: 9-10 month flowering, fruit ripening in 4-5 months. A blue black, can be cooked in fruit picking, natural shedding. Fruit after composting, to peel after softening, soaking rub to peel, remove clean, slightly dry after sand (sand storage humidity control in hand into a group to let go natural loosen, such water is about 5%). Seed weight of 200-300 grams, kg per kg, germination rate of more than 60%.
Seedlings: nursery should choose fertile, deep soil moisture. Winter or spring sowing, the drill, due to slow growth in seedling stage, so the first year seedlings should be dense, the sowing rate of 30 kg per mu.
Seedling management: Seedling shade tolerance and slower growth, susceptible to harm of anthrax, available Bordeaux prevention, and strengthen the field drainage and shading and fertilizer management. Annual seedling height of about 30 cm, the following year early spring transplantation.
Cutting seedlings: in order to ensure the purity of the varieties are generally used to breed seedlings cuttings. In the 5-6 month, cut trees on the semi lignified branches, cuttings generally stay 2-3 internodes, about 7-10 cm long, with shear plug. Cuttings only leaves two leaves at the top, and the depth of insertion is 1/3 or 1/2. The cutting density was not overlapped with each other. In order to promote the development of early new roots, can use the plug before rooting powder or naphthylacetic acid dipping skewer panicle 3-5 cm. After cutting, fully watering, make the cuttings and soil closely, cover plastic film small Gongpeng, seal, and upper shade net shed.
Cutting seedling management: osmanthus cuttings, water should not be too much, otherwise it is easy to rot. So in rainy season must pay attention to drainage. In the early days of rooting and high temperature and dry weather to spray water in the leaves, keep the leaves often in a wet state. A month after cutting in high shade shed and small plastic arch shed to cover, avoid sunlight penetration. Two months later, sooner or later slightly affected by the sun. In October can be removed gradually increase the light and shade, promote hair root, November demolition of shade shed, greenhouse type cold winter reconstruction.
Cultivation: 3-4 months or autumn transplanting the best, transplanting should not be too deep, and appropriate pruning crown, reduce water evaporation. Fertilizer was applied in winter and July each year. I should pay attention to watering, florescence control watering shoulds not be too wet. Winter pruning, the diseased branches, weak branches and endogenous branches cut off, and cutting short leggy branches.
Pest control: orange leaf disease, leaf spot and angular leaf spot disease occurs or available Bordeaux sweet scented osmanthus, 50% carbendazim WP 1000 times liquid spray. Infestation with red spider, whiteflies, scale insects and pests in distribution, spraying with 40% Omethoate EC 1000 times liquid.
