In other words, distinguishing tung tree, phoenix tree and paulownia is an important work to vigorously develop urban greening and beautification. Paulownia, Paulownia and Indus seem to play a very important role in urban landscaping and are often confused. In fact, these three tree species belong to different families and genera, and there are also great differences in morphology.

Fatong pictures

One: first understand Fatong:

Second; Let's meet the phoenix tree again;

Wu Tong, also known as Qingtong, also known as Wu Tong, China, is a deciduous tree of Wutong family, with a height of 20 meters. The crown is oval, the trunk is straight and the bark is smooth and green. Branchlets are stout and emerald green.

When the fruit matures, it splits into five boat-shaped petals, and the seeds are spherical and attached to the edge of the petals. The Indus River originated in China. Like light, warm, fertile, moist, sticky, well-drained, calcium-rich soil, not resistant to waterlogging, cold, weak germination and pruning. Leaves began to appear in the lower reaches of the Yangtze River in the middle and late April, turned yellow in autumn and fell early. The buttonwood leaves are green, tall and dignified, and the shade is deep. Since ancient times, people like to plant buttonwood trees in the courtyard. Indus is a beautiful tree with shady green leaves, which can attract birds to live and breed. It is a good tree for greening in front of the courtyard.

Three: Next, I want to know about Paulownia:

Paulownia, also known as "Tung", is a deciduous tree belonging to the genus Paulownia of Scrophulariaceae. Its height can reach 27 meters, its crown is broad, its bark is smooth and grayish-brown, its single leaves are opposite, and its heart-shaped ovoid to heart-shaped ovoid is completely or slightly wavy. In spring, there are flowers first, then leaves. Corolla lip-shaped, white or lavender, with purple spots and fragrance. Paulownia is a special product in China, which is widely distributed. At present, the main varieties are more than ten kinds of Paulownia Bunge, Paulownia Lankao, Paulownia tomentosa, Paulownia albiflora, Paulownia Sichuan and Paulownia Lankao. Paulownia has sparse branches and leaves and a wide crown. In April, clusters of purple flowers or white flowers bloom and smell fragrant. The leaf coat secretes a sticky substance, which can absorb a lot of smoke and toxic gases. It is an excellent tree species for urban greening and shelter forest construction. Paulownia is cold-resistant, drought-resistant, salt-tolerant, wind-blown sand-resistant, and has strong adaptability to climate. When the temperature is higher than 38℃, its growth is affected, and its absolute minimum temperature is frozen at MINUS 25℃. Easy to breed, fast to grow and excellent in material. It is a special material for musical instruments and airplane parts, and the root bark is used as a medicine to treat falls and injuries. Original link /a/news/24722.html?
