To create poplar fast-growing and high-yield forest is to solve the crisis of forest resources, shorten the rotation period, speed up the cultivation of reserve forest resources and achieve sustainable use of strategic measures. The Mudanjiang forest area has the natural advantage of developing poplar forest and is an important area for the country to develop high yield forest.
