Unknotted Pinus sylvestris

Russian Scotch pine, a plant of the genus Pinaceae, has the characteristics of strong cold resistance, strong adaptability, strong resistance to stress and long life, and has many uses
.
Characteristics of Pinus sylvestris
It is an evergreen tree with a tree height of 1 meter, a maximum height of 1 meter, and a maximum diameter (diameter at breast height) of about 1 meter. The crown is ovate to broadly ovate, and the old bark is thicker, longitudinally split, dark brown, and often cracked in scales. The bark on the upper part of the trunk is very thin, brown or light yellow, and the thin bark falls off. Pinus sylvestris is a positive tree species with a sparse crown. The needles are mostly concentrated on the surface of the tree. When there is a lack of side light in the forest, the trunk will naturally prun quickly. When isolated or with sufficient side light, the side branches and needles will be luxuriant and young. Tree
Grows poorly under the canopy.
Pinus sylvestris has strong cold tolerance, can tolerate low temperatures to ℃, is drought-tolerant, and does not require soil moisture. The crown is sparse, and the needles are sparse and short. The epidermis of the needles is horny and has a thick fleshy part. The stomata are located in the depressions of the leaf folds. The stem epidermis and lower epidermis are very thick, which can reduce
Less transpiration from aboveground parts. At the same time, on dry sand dunes, the main root is generally 1 meter deep, with the deepest being less than 1 meter. The lateral roots are mostly distributed in the sand layer
centimeters above the surface. The root system stretches around and can fully absorb the water in the soil.
Pinus sylvestris has strong adaptability. It can grow well on nutrient-poor sandy soil and mountainous gravel soil with very thin soil layer.
Pinus sylvestris is highly resistant to stress. According to a survey, the annual Pinus tabulaeformis has been harmed by pine needle rust, while the adjacent Pinus sylvestris has suffered less damage and is more resistant to the damage of pine stem borer than Pinus tabulaeformis
.
Pinus sylvestris has a long lifespan, usually up to 20 years, and some up to 10 years.
