摘要:本文通过对树木中水的吸收与运输过程的描述,讨论与分析影响树木生长高度的三个主要因素:毛细现象、蒸腾作用、根压。通过理论的分析与计算,测算出水在树木中上升的高度,由此推测树木的高度,并将理论数据与某种树木的实际高度相比较,分析其中的差异,做出定性的结论。
关键词:毛细现象;蒸腾作用;根压;水的运输
Abstract: Based on the trees in the water absorption and transportation process description, discussion and analysis of tree growth height of three main factors: capillarity, transpiration, root pressure.
Through theoretical analysis and calculation, estimated increase in water height in the trees, which indicated that the height of the trees, and some kind of theoretical data pare the actual height of the trees to analyze the differences, to make qualitative conclusions.
Keywords: Capillarity;trans
