| 摘 要： | 研究了5种不同施肥处理对6.5年生尾叶桉无性系单株材积、木片密度、纤维形态的影响规律。结果表明:施肥处理显著加快尾叶桉生长速度;对木材密度影响甚微;对纤维长度没有显著的影响;使纤维宽度显著增加。但并非施肥量越多,生长速度越快,纤维宽度越宽。尾叶桉无性系短周期速生林木是一种优良的、有发展前途的造纸原料。

| Abstract: | In order to investigate the effects of fertilization on pulpwood quality of Eucalyptus urophylla clones.Wood samples of 6.5 years old E.urophylla clones tree were collected from five plots with different fertilization treatments in Kaiping city,Guangdong province.This paper deals with volume per individual, gravity and fiber formation of E.urophylla wood from plantation.The results are as follows:(1)Fertilization treatments significantly promote the growth of E.urophylla clones.(2)There are no significant effects on average gravity with the different treatments.(3)Fertilization treatments have not obvious effects on fiber length,whereas having a significant effect on fiber width by increase.However,the increasing tendency of fiber width can not be attributed to the increased fertilization. (4)The wood of E.urophylla clones with a short-term is a good and advanced source of pulping material. |
