本文论述了桉树选优的主要原理和在选优实践上所应遵循的一些基本原则。根据这些原则,针对桉树短周期工业用材林(纸浆材)这一选择目标,提出了桉树选优的有关标准和方法。选优参数中的木材基本密度要求在500～600kg/m~3,制浆得率大于50％。选择年龄为林分有机会充分地自身表现出各个优势性状的年龄。
This article discusses the main principles of Eucalyptus selection and some basic principles that should be followed in the selection of excellent practices. According to these principles, the eucalyptus selection criteria for short-period commercial timber plantation (pulpwood) are put forward. The optimal wood basic density requirements in 500 ~ 600kg / m ~ 3, pulp yield greater than 50%. The age at which the stand is selected has the opportunity to adequately represent the age of each predominant trait.
