氮、磷是树木必需的矿质营养，在自然界中它们影响着树木个体的生长、群落的发育及整个生态系统的生产力。
Nitrogen and phosphorus are the necessary mineral nutrition to trees. They determine the growth of individual, the development of community and the productivity of ecosystem in the nature.
关于树木个体发育中成熟和幼化，包括幼年性、成年性及其关系与利用的问题，越来越多地引起了人们的关注，成为今天无性系育种中的重要课题。
The tree's individual developing about maturation and rejuvenation including yang growth and majority of them, are attracting the people even more , so it has been an important task.
阅读和研究树木的行为——这个话题他在林业学校中学习得甚少——他发现，在自然界，树木更多时候不是以个体形式生活，而是像社群一样。

That means that for most threatening conditions, for climate, insects, and pests, whatever, there will be at least some individual trees of any given species tree that are resistant.
结果表明：各种植被类型中物种数与个体数对数成线性关系是一种普遍现象，且不受调查树木的径木级影响。
The results indicate that the rate of species accumulation is related to the logarithm of number of individuals in each vegetation type, independent of diameter classes.
