Larix is ​​a deciduous tree of the genus Larix of the Pinaceae family. It has abundant wood accumulation. It is the main forest component tree species in the forest areas of Northeast China, Inner Mongolia, and the alpine coniferous forests of North and Southwest China. It is also the future afforestation and forest regeneration of barren hills in this region. The primary tree species is one of the top three coniferous timber forest species in Northeast China. It is also often used as building materials such asLarch wood pile, larch furniture.

Larix has a wide natural distribution. It is a tree species in cold temperate and temperate zones. It is the most cold-resistant among coniferous species. Its vertical distribution reaches the upper limit of forest distribution. The main reasons for larch's natural distribution and artificial cultivation in northern my country are Xing'an larch, Landrace larch, North China larch, Japanese larch and Korean larch. The cones of the larch group are oval or long oval, the bract scales are shorter than the seed scales, not exposed or the tips are exposed, and the branchlets are not Drooping (national larch, yellow-flowered larch, North China larch, Siberian larch and the introduced Japanese larch and European larch belong to this group). Very suitable asLarch wood pile　　

Larch trunks have straight ends, few knots, obvious differences between heartwood and sapwood, tough raw materials, slightly thick structure, and straight grains. It is a wood with strong corrosion resistance and mechanical properties among Pinaceae plants, and is suitable for construction, poles, and bridges. , used for boat carts, sleepers, springwood, ore pillars, furniture, appliances and wood fiber industrial raw materials. The tree is up to 35 meters high and has a diameter at breast height of 90cm. The bark is gray, dark gray or gray-brown, with deep furrows and longitudinal splits. The flakes fall off, and the scratches are purple-red; the cross section after breaking is dark brown. The wood is slightly heavy, medium hardness, easy to crack, the sapwood is light yellow, the heartwood is yellowish brown to reddish brown, the grain is straight, the structure is fine, and the specific gravity is 0.32-0.52. It contains resin and is durable. It can be used for housing construction, civil engineering, electric poles, boats, fine wood processing and wood fiber industry raw materials. Resin can be extracted from the trunk, and tannin can be extracted from the bark.

Made of larchLarch wood pileIt is heavy and solid, has high strength against compression and bending, and is resistant to decay. It has high wood craft value and is an excellent material for poles, sleepers, bridges, mine pillars, vehicles, buildings, etc.
