摘  要:
在淮北平原宿县试验林内,米集了氮肥+有机肥、磷肥+钾肥、未施肥(对照)三种条件处理的I-69杨(Populus deltoides Bartr.cv.“Lux”ex I-69/55)试材36株。进行木材解剖、化学成分、木材物理力学性质等试验,结果表明:施肥处理生长快的I-69杨,木材纤维长度α-纤维素、综纤维素和木材气干密度等稍有下降,方差分析验证,差异未达显著水平。其中施用氮肥+有机肥生长最快的I-69杨,胶质纤维比率高;木材抗压强度、抗弯强度等均有不同程度的降低。抗弯弹性磨量、顺纹抗剪强度、径面与弦面硬度等降低差异达显著水平。

摘  要:
In Shu County, Huaibai Plain, 36 sample trees of Populus deltoides cv."Lux" ex Ⅰ-69/55 were collected from three poplar fertilization trial planta-tions (trial plantations of N+organic fertilizers, P+K and check) to study thewood anatomy, chemical composition and wood physical strength of thesetrees. The results are as follows: 1. In the fertilized plantations, the poplarsgrow fastor, wood fibre length, amount of a-cellulose, and holocellulose,and wood air-dry density of these trees lower down a little; after the testingof variance analysis, their variances does not reached remarkable level; 2.The poplars with a fastest growth in the trial plantation of N+ organic fer-tilizerc, whose rate of gelatinous fibre is higher, but their crushing strength,bending strength, shear parllel to the grain shearing strength and hardnessdecline to a certain extent separately; the decline variances of shear to thegrain shearing and hardness haven't reached remarkable level.
