Schima Superba - это вид цветущего растения в The Tea Family Theaceae , родом из субтропических районов Вьетнама, южного Китая, Хайнана , Тайваня и островов Рюкю . [ 2 ] С Pinus Massoniana он часто доминирует в лесах от 100 до 800 м (от 300 до 2600 футов) на высоте. [ 3 ] [ 4 ] [ 5 ] Он используется в качестве уличного дерева в ряде южных китайских городов. [ 6 ]
S. Superba имеет долгую историю в Китае, он был описан уже в « Классике гор и морей », и в этом классическом тексту это одно из «священных деревьев». [ 7 ] S. Superba -это драгоценные и многоцелевые виды деревьев.

Листья кожистые, овальные, длиной 7-12 см, часто плотно выращиваемые на кончике ветвей. Цветы белые, гермафродиты, диаметром 3 см, часто растягливы на кончике ветвей или в пазухи верхних листьев ветвей. Цветы ароматны. Плод представляет собой капсулу , шаровидную или субглобозу.

Uses
[edit]- Fire prevention
S. superba is an excellent tree species for building fire-proof forest belts in southern China. Its leaves have a high water content, a fire temperature of 450 °C, and a low oil content of only 6%, making it non-flammable.[10] Moreover, it is adaptable, grows rapidly, and has a dense and compact canopy. When the forest belt is 14.5m wide (four rows) and 5-6m high, it can prevent the fire from spreading.[10] Because it often forms forests with Pinus massoniana, Cunninghamia lanceolata and other evergreen broad-leaved trees, it can also play a partial fire-blocking effect.[7]
- Ecological protection
S. superba is an efficient ecological protection tree species in southern China. It has excellent water and soil conservation function. It is a deep rooted tree species with strong adaptability to soil, and can grow healthily in various acidic soils.[7] It can tolerate dryness, barrenness, short-lived low temperatures of - 10 °C, and heat of 39 °C.[10] S. superba is suitable for mixed forest with Pinus massoniana, Cunninghamia lanceolata and other evergreen broad-leaved trees, suitable for low-quality and low-efficiency forests, and suitable for ecological restoration of forest lands after bursaphelenchus xylophilus is eliminated.[7] It is an excellent mixed afforestation or alternative tree species for the regeneration of the second generation of Cunninghamia lanceolata and Pinus massoniana.[7]
- Wood
The wood is hard, dense, less cracked and easy to process. The color of the material is relatively uniform, and the longitudinal section is shiny. It is used for making gunstocks and yarns and cop tubes in the textile industry; it is also used for bridges, ships, buildings, farm tools, furniture, plywood, etc.[7]
- Medicine
"木荷 mù hé/tree-lotus" is the official Chinese name of S. superba. "木荷 mù hé" and "木荷葉 mù hé ye/tree-lotus-leaf" are both names of traditional Chinese medicines, and also medicines for external application. The raw material of "木荷 mù hé" comes from the bark, which can "攻毒/attack poison" and "消腫/reduce swelling". The raw material of "木荷葉mù hé ye" comes from the leaves, which can "解毒/detoxify/" and "療瘡/cure sores/".[11]
- Others
S. superba has a beautiful tree shape, large and fragrant flowers, and is an excellent landscaping plant. It is also a honeyed plant. The bark and leaves contain tannins. According to research, the bark may contain some toxic substances such as saponin, which are highly toxic to cold-blooded animals, certain insects and fish, and can be used to develop pesticides.[7]
