The study on the growth characteristics of Populus euphratica showed that Populus davidiana exceeded the local poplar poplar in terms of growth, with volumetric growth over 73.4% -26.92% of Populus davidiana. The area grew more than the present Northeast, Inner Mongolia and North China Area of the fine poplar varieties. The growth pattern of Populus davidiana and suitable planting density were discussed, and the growth of Populus euphratica was divided into five periods, which provided a scientific basis for the rational management of poplar.
