Cedar can be as high as 30 meters, and its DBH can reach 3 meters. Bark dark gray, split into irregular scales; Branches are flat, slightly inclined or slightly drooping, basal bud scales are bent outward, and branchlets are often drooping. Annual branches are grayish yellow, densely covered with short villi and slightly powdery. The branches in the second and third years are gray, light brown gray or dark gray.

Leaves grow radially on long branches. Short branches and leaves are clustered, needle-shaped, hard, light green or dark green, 2.5-5cm long,1-1.5mm wide at the upper part, sharp at the top and narrow at the lower part, often triangular. There are 2-3 stomatal lines on both sides of the ventral surface of the leaf, and 4-5 on the back surface. Male cones are ovoid or oval, 2-3 cm long and about 65438 0 cm in diameter; The female cone is ovoid, about 8 mm long and 5 mm in diameter.

Seedlings with a diameter of 5 cm and a height of 2.5 meters can be cultivated for three to five years, and then used as seedlings for greening projects. The easiest season to survive is March every year. Of course, for engineers and technicians with construction experience, construction can be carried out all year round, and the survival rate is above 90%.

When digging seedlings with soil balls, the size of soil balls can be determined according to the standard of DBH 1 to10-2, so as to ensure the survival of seedlings. For example, for cedar with ground diameter 10 cm, the soil balls should not be less than100-1.

Cedar pruning is the most difficult task. It is different from other tree species. Generally, after the cedar is pruned, the original plant no longer grows new branches. Therefore, proper pruning should be taken at that time, and pruning should be even, so as to ensure the beautiful tree shape and keep the tree shape full and beautiful.
