Chinese fir.

is a fir family, a genus of fir trees. Also known as: sand, sand trees, hedgehogs.


Form:

, up to
30m, chest diameter 2. 5-3。 0m. The canopy is minaret-shaped in its inflect years, the large trees are widely conical, the bark is brown, and the cracks grow and fall off the flakes. Leaf-shaped or strip-shaped needle-shaped, often slightly curved and sickle-shaped, leathery, hard, dark green and shiny, 2-6cm long, 3-5mm wide, in a fairly coarse main branch, trunk also often have anti-roll-shaped dead leaves, spherical round to round, long 2. 5-5cm, diameter 2-4cm, ripe scaly leather, brownish yellow, seed long egg or long round, flat, long 6-8mm, dark brown, with narrow wings on both sides, each fruit contains about 200 seeds; Flowers bloom in April and fruit ripens in late October.


Distribution:widely distributed, north from the Huaihe River south, south to Leizhou Peninsula, east from Jiangsu, Zhejiang, Fujian coast, west to the southeastern valley of the Kang-Tibet Plateau are distributed, in
16 provinces have growth, about 800 km south, 1000 km wide east-west. The upper limit of vertical distribution varies according to edoe, such as below 700m above sea level in Dabe Mountain, below 1000m in Fujian Mountain, and below 2500m in Dali.


Habits:

positive tree, warm and humid climate, cold, absolute minimum temperature is not less than
-9 degrees C is appropriate, but can also resist -15 degrees Celsius low temperature. Rainfall of more than 1800mm as the best, but more than 600mm can also grow, fir cold resistance is greater than its drought resistance. Therefore, the main factors that restrict the growth and distribution of fir trees are first the wet condition and the second is the temperature condition. Fir magpies are fat and thin, afraid of salty soil, the most like deep fertile drainage of good acidic soil (PH4). 5-6。 5), but can also grow on micro-alkaline soils. Fir is one of the fast-growing tree species. The 20-year-old tree is about 18 years tall. 0m, chest diameter 18. 5cm. However, depending on the environment, the fastest person is born up to 9m in 6 years, and 7m in 20 years on a ridge with a barren
dred
soil layer. Its fastest growing period is around 4-14 years. Generally 5 years can start to strong, but the growth in the forest often at 15-20 years old. Life expectancy can be more than 500 years. Fir root system is strong, easy to grow uncertain roots, germination and renewal ability is also strong, although by fire, can also re-create strong germination; Therefore, the germination updater can also grow into a trees.

Landscaping:

the main fir trunk straight, most suitable for gardens planted in groups into forests or lined up next to the road.
Britain in 1804 and 1844 and grew well in the south of England as a prized ornamental tree. Cultivated in botanical gardens in the United States, Germany, the Netherlands, Poland, Denmark, Japan and other countries.
