Ecological classification: woody plants >; hardwood

Ornamental classification: forest trees

Height range: 50 meters

Morphological characteristics: When DBH is over 3m, the crown of the young tree is conical, while the old tree is umbrella-shaped, with a sharp trunk and a bent respiratory root at the base. Peel long strips of bark; The branches are flat, and the branches of big trees droop slightly; 1 year-old branchlets are brown, with leafy lateral branches arranged in 2 rows. The leaves are strip-shaped, 1.0 ~ 1.5 cm long, flat and sharp, arranged in two rows of plumes, with concave upper midvein and light green, and turned dark reddish brown before falling in autumn. Cones are spherical or ovoid, about 2.5 cm in diameter, and light brown when mature; The seeds are brown, long 1.2 ~ 1.8 cm, and flowering in May. The cones matured in June 5438+the following year 10.

Growth habit: masculine, warm-loving, water-resistant and moisture-resistant. It can grow in shallow swamps and well-drained land. Growing on the wetland, the base of the trunk can form a plate root, which protrudes from the horizontal root system to the ground, especially called "knee root". The best soil is moist and rich in humus. The origin can form a large forest. Strong wind resistance.

Propagation and cultivation: it can be propagated by sowing and cutting. Hard wood or soft wood can be used for cutting propagation. After planting, it is mainly to prevent the central trunk from becoming double trunk, especially in cutting and seedling raising. If there are double stems, cut off the weak stems, keep the strong stems, and thinly cut off the twigs and long branches that affect the growth of the trunk.

Landscape uses: courtyard shade trees, waterside revetment trees. Taxodium ascendens has a neat and beautiful tree shape, and its nearly pinnate leaves are extremely beautiful. In autumn, its leaves turn bronze, so it is a good autumn leaf tree. Waterfront planting is the most suitable, which has the function of wind and bank protection. Taxodium ascendens is the same as Metasequoia glyptostroboides, Metasequoia glyptostroboides and Sequoia.
