Zhongmu 1 # Yang was Mudanjiang Forestry Science Institute in 1983 from the Chinese Academy of Forestry introduced the United States black × Poplar hybrid clonal breeding clones. After 20 years, it has been proved that this variety has the excellent characteristics of fast growth, good material, good dryness, high survival rate of cuttage seedling and afforestation, strong resistance to stress and so on. The volumetric growth rate is increased by 28.6% 4 4. 5%, air dry density of 0.387g / cm3, fiber length of 1.0 94mm, are higher than the spring # 5 # Yang; suitable for southeast Heilongjiang Province and the eastern plain of Jilin Province and shallow mountain area to promote the use.
