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。
Through the initial planting density test of Populus euphratica, the relationship between the growth indexes such as initial plant density, DBH, single plant volume and area per unit area was mastered, and the effect of fertilization on the growth of trees was ascertained. The initial planting density was 1111-1667 plants · hm 2.
