Populus euphratica is a plant that is not afraid of heat and can tolerate high temperature of 45℃. Growing in the desert, it can not only resist heat, but also resist harsh environments such as drought, salinity and sandstorm, and has strong adaptability to large temperature changes.
Because the water needed for its growth mainly comes from diving or river flooding, its root system extends to the vicinity of the phreatic layer, with strong root pressure and leaves containing sodium bicarbonate.
We can judge the water level according to the growth trajectory of Populus euphratica. Because Populus euphratica relies on roots, as long as the groundwater level is not less than 4 meters, it can live comfortably; After the groundwater level drops to 6-9 meters, there will be stagnant flow; If the groundwater level is lower, it will die.
Morphological characteristics:
Populus euphratica can sprout seedlings from the roots, can endure the arid environment in the desert, and has strong saline-alkali tolerance. Bark is grayish brown, and the lower part is cracked; The sprouted branches are thin, round, smooth or slightly fluffy.
The bud is oval, smooth and brown, about 7 mm long. Leaves on long branches, seedlings and young trees are linear-lanceolate or narrowly lanceolate, with entire or irregular sparse wavy tooth margins; Adult tree branches are muddy yellow, short fluff or hairless, and the branches are rich in salt and salty in mouth.
