【摘要】通过大青杨初植密度试验,掌握了初植密度和胸径、单株材积、单位面积蓄积量等生长指标之间的关系,了解了施肥对树木生长的影响,确定了培育大青杨纸浆材的适宜初植密度是1111～1667株·hm 2。更多还原

【Abstract】 Through trial on initial density of Populus ussuriensis, the relationships of the density and some growth indexes such as DBH, individual volume, and unit area volume were revealed, also including the impact of fertilizer application on forest trees. The trial results showed that optimum initial densities of Populus ussuriensis were 1 111～1 667 trees per hectare.更多还原
