| 摘 要： | 土壤上层（≤20cm）容重较低，中下层（≥20cm）较大，且上层土壤含水量、通气度、总孔隙度、有机质都较中下层优越，因此草根在上层的积累量远远大于下层的积累；但三倍体毛白杨生物量积累的变化是：中层〉下层〉上层，作用规律性不强，因此有待进一步研究。

| Abstract: | The soil's weight in the upper layer is much lower than that in the middle and down layer,and the water content,aerating degree,total space degree, organic matter were the other way round,so the grass root biomass in the upper were much higher than that in the down layer.But the change of biomass accumulation of Triploid populus tomentosa is:Middle layer> down layer >upper layer.And the relation of growth characteristic and soil's physical properties remained to be studied further. |
