There are about 9 genera and more than 90 species in the world. The standard type of cycad is cycas, which is mostly planted in the north. It is mainly planted in Fujian, Taiwan, Guangdong, Guangxi, Jiangxi, Yunnan, Guizhou, etc. It is also planted in China, Japan, the Philippines, Indonesia and other countries. It needs to be planted in winter. Overwintering indoors, its flowering is also very famous, known as "iron tree flowering". cycads. Common name: iron tree, alias: fire plantain, phoenix banana, phoenix pine, phoenix grass, Latin name: Cycas revoluta Thunb. It once dominated the earth at the same time as the dinosaurs, and is hailed as a "living fossil of plants" by geologists. Cycad is a succulent plant. Cycad is a cycad plant with a trunk about 2 meters high, and the appearance of all pinnate leaves is obovate and narrowly lanceolate, 75-200 cm long. Cycad plant category Cycas is a herbaceous plant belonging to the phylum Cycad, Cycadaceae, and genus Cycas. The plant is 2-8 meters high. Cycads, Longkou Cycads, Brazilian Cycads, Hainan Cycads, Sichuan Cycads, etc. What are the characteristics of cycads 1. There are bright cycads with sharp tips and dense rusty hairs on the back of leaves. It likes full sunshine of cycads, not resistant to sun exposure, and resistant to half shade. For short-day plants, planting under the premise of long-day sunlight will affect flowering. Hi second, the suitable temperature for growth is 15-28°C, and it is easy to be damaged by freezing at 0°C. The accumulated temperature for flowering needs to reach above 3000-4000℃. Root fleshy, not waterlogging tolerant. 2. The trunk of cycads is cylindrical, thin, dark brown, covered with relics of diamond-shaped petioles arranged in a spiral shape, rarely branched, and can reach a height of 8 meters. Large pinnate leaves, born on the top of the trunk, with more than 100 pairs of pinnate lobes, dark green, shiny, and the edges of the lobes are rolled back. Flowers unisexual, large and small sporophyll dioecious. 3. The stems of cycads are densely covered with persistent leaf bases and leaf scars, and are scale-like. The leaves are enumerated in a spiral, and the leaves emerge from the top of the stem. The leaflets are linear, rolled inward when they were born, and then spread upwards obliquely, slightly in the shape of a "V", with the edges revolving downwards obviously, thick leathery, firm and shiny, and sharp at the apex. 4. Cycads, also known as cycads, phoenix-tailed bananas, and cycads, belong to the small evergreen trees of the cycad family. The stems are thin and erect, brown-black, with few branches, and the trunk is as strong as iron. It likes iron fertilizers happily, so it is called iron tree. Older stems are covered with remnants of spirally enumerated diamond-shaped petioles. Cycads are national protected plants at several levels 1. Cycads are national first-class protected plants. Cycas, commonly known as iron tree cycads, is said to be named cycads because of its high wood density, which sinks in water and is as heavy as iron; another theory is that it needs a large amount of iron to grow, so it is named. 2. Shishan cycad is a national first-class protected plant in China. Shishan cycad is a plant of the genus Cycas in the cycad family. The trunk is short, the base expands into an egg-shaped stem or a disc-shaped stem, and the upper part gradually shrinks into a cylindrical or egg-shaped cylindrical shape. It is 30-180 cm high or slightly higher, and its diameter is 10-60 cm. centimeter. 3. Yes. Iron tree belongs to the cycads of the genus Cycas in the cycad family. In the national directory, "Cycas" has been listed as a first-class protected plant. Cycas brief introduction Cycas alias cycas, phoenix palm, phoenix banana, Thoreau flower, iron armor pine, Phnom Penh phoenix 4 origin Cycas Cycans revoluta Thunb, a plant of the Cycad family Cycas, uses leaves, roots, flowers and seeds as medicine. The roots and leaves can be collected in four seasons, the flowers are collected in summer, the seeds are collected in autumn and winter, and dried in the sun. Cycads are not ferns. Cycad, also known as iron tree, is the most primitive succulent plant existing on the earth. It is not a fern. , evergreen in all seasons, black and often sad ornamental plants. Cycas brief introduction: Cycas, an evergreen plant belonging to Cycadaceae, is palm-shaped, with a cylindrical trunk, triangular-ovate scale leaves, thorny petioles, densely covered with yellow-brown felt hairs when young, and obovate-shaped vegetative leaves. Needle-shaped, male cones cylindrical. Cycas is most famous for its flowering, which is called "iron tree flowering". Cycads are dioecious, with different flower shapes. The male flowers are long ovate, standing among the green feather leaves, yellowish brown; the female flowers are oblate, light yellow, clinging to the top of the stem. The flowering period is June-August. Seeds ovoid, slightly flattened, white when ripe. Brief introduction to the species of Panzhihua cycads 1 Panzhihua cycads are also known as iron trees. According to relevant records, they first appeared in the Paleozoic Permian cycads of the earth 280 million years ago. They are "living fossils" of plants. good name. What does cycad mean?
