杨树是山东省主要造林树种之一,确定最佳采伐周期、造林密度、混交方式,是提高生物量的关键技术。经多年定位观测试验得出:杨树造林密度为2 m×2 m,采伐周期为5a生物量最高;杨树生物量结构为:树头占23%~26%,树干占50%~52%,树根占22%~26%;树根生物量约有80%~90%分布在0~40 cm土层内。杨树不同密度单株生物量和单位面积生物量不同,密度增大,单株生物量减少,单位面积生物量增加。生物量结构和生物量估测模式的研究,为深入研究杨树栽培技术、木材加工业等提供相关参数。本试验选取了5年生杨树不同部位生物量的估测模型。

Poplar is one of the main afforestation tree species in Shandong Provicne. Defining the best cutting period,afforestation density and mixed mode is the key technologies to promote biomass.The located observation experimentations addressed to these key technologies have been conducted for many years. The results showed that the biomass of poplar forest with density of 2 m×2 m and cutting period of 5 a was the highest.The biomass of poplar consists of tree crown accounting for 23%~26%, the stem accounting for 50%~52%,and the root accounting for 22%~26%. About 80%~90% of root biomass was distributed from 0 cm to 40 cm depth in the soil layer. The biomass of individual plant was decreased and contrarily the biomass on unit area was increased along with the increase of density. The biomass estimation models of several parts of five-year old grown poplar tree were selected. Some relevant parameters were given by studies on biomass structure and biomass estimation models. The results will be helpful to further research into poplar growth technologies and wood process etc.
