Geographical distribution of Metasequoia

Metasequoia glyptostroboides can be cultivated in the south of Beijing. It grows well at the junction of Hubei, Chongqing and Hunan. The vertical distribution is generally 750 ~ 1500 meters above sea level

Morphological characteristics of Metasequoia glyptostroboides

Metasequoia glyptostroboides is a deciduous tree, which can be up to 35 meters high and 2.5 meters in diameter, with opposite branchlets. The leaves are linear, opposite and pinnate compound leaves. The upper surface of the leaves is light green and the lower surface is light. There are two 4-8 light yellow stomatal bands along the midvein.

Metasequoia growth environment

Metasequoia like warm and humid climate conditions. It mostly occurs in places with flat terrain, deep soil layer, moist or slightly ponding. Acidic mountain yellow soil, purple soil or alluvial soil are suitable for its growth; The optimum growth temperature of Metasequoia glyptostroboides is about 18 ℃, which is cool in summer and can grow with snow but not cold in winter; Metasequoia glyptostroboides has a pleasant light, is not resistant to barren and drought, and its growth speed is often dominated by soil moisture. It is easy to survive transplanting. In places with long-term ponding, the plant grows slowly, and the base of the trunk is usually expanded and has longitudinal edges
