小黑杨是黑龙江省平原地区的重要造林树种。许多研究表明,小黑杨林的木材产量和抗性同外界环境条件相关,特别是与林地的保水性关系密切,例如,生长在粗骨母质颗粒状土壤(地下水位2～3米)上的15～20年生小黑杨林,其木材蓄积量为300～400米~3/公顷,木材纤维质量也较好,而生长在地下水不足的林地上的小黑杨林, Small black poplar Heilongjiang Province is an important afforestation tree species. Many studies have shown that wood production and resistance of Populus davidiana are related to environmental conditions, especially the water retention of woodland. For example, the growth of wood in coarse-grained parent soil (groundwater level 2-3 m) 15 ~ 20-year-old black poplar, its stock volume of 300 ~ 400 m ~ 3 / ha, wood fiber quality is better, and grow in the groundwater shortage of woodland on the black Poplar,
