Detailed Explanation of the Characteristics and Cultivation Techniques of the Large-leaf Privet
Scientific name Ligustrun lucidum Ait., also known as wax tree, Oleaceae, Ligustrum genus. It is an evergreen large shrub or tree, with grayish-brown bark, smooth and not fissured. The leaves are 8-12 cm long, leathery and glossy, remaining green through winter, making it a rare evergreen broadleaf tree in temperate regions. The trunk is upright or two or three trunks emerge together, branches spread obliquely, forming a broad ovate, rounded crown. It can be planted as a street tree, tolerates pruning, and is commonly used as a hedge. The wood is fine and dense, used for joinery. The fruit contains starch and can be used for brewing wine, and is also used medicinally as a tonic. The leaves can treat stomatitis and pharyngitis; the bark ground into powder can treat burns and scalds; the rhizome soaked in wine treats rheumatism. The large-leaf privet likes light and warmth, tolerates slight shade, but is not cold-resistant. It grows rapidly in slightly acidic soil, and can also grow in neutral and slightly alkaline soil. It has strong sprouting ability and a wide range of adaptability. It has the function of retaining dust and resisting smoke, can absorb sulfur dioxide, and is suitable for factory and mining area and urban greening. It is one of the rare evergreen broadleaf tree species in the north.
Flowers are bisexual, in terminal panicles. The flowering period is July, and the fruit ripening period is October-November. The berry is long elliptical, purplish-black, and the seed is obovate. After the fruit matures, it does not immediately fall off on its own. You can use long-reach pruners to cut the fruit clusters, strip off the fruits, soak them in water, rub off the fruit skin, and dry them slightly. The thousand-grain weight of large-leaf privet seeds is about 36 grams, with 27,000 seeds per kilogram, and a germination rate of 50-70%. The seeds can be stored mixed with sand at low temperature and high humidity, or stored with the flesh at low temperature.
Large seedlings should be with mud balls, and part of the branches and leaves should be pruned off. For seedlings planted as hedges, cut the stem 15-20 cm above the ground to promote the sprouting of side branches.
