为了阐明树木根系的分布范围和形态结构,在起源于1939年、未疏伐过的29年生王桉林分中进行了挖掘。观察到每厘米胸径,相应的根系横向分布的最大值是0.17米;优势木的根冠比(rootlcrowu),最大值为3.8。优势木根蔸下,根的深度达2.6米,而树干外围的根,其烘干重量的98％存在于表面60厘米的土壤中。植株之间和同一植株内根的接合体均有发现,61％的植株,有植株之间的接合。检查挖掘出来的接合体指出:这些接合体从一根系到另一根系的物质输导能力,可以有很大的不同。显微镜观察表明,不定根通常在主根根系上发生。
In order to elucidate the distribution and morphological structure of the tree roots, excavations were carried out in 29-year-old eucalyptus forests that originated in 1939 and were not loosed. Observed per cm diameter, the corresponding horizontal distribution of the root maximum is 0.17 meters; dominant wood root to root ratio (rootlcrowu), the maximum value of 3.8. Under the root, the roots reach a depth of 2.6 m, while the roots of the trunk periphery, where 98% of the dried weight is present in 60 cm of the surface soil. Between the plants and within the same plant root adapter were found, 61% of the plants, there are joints between plants. Examination of excavated joints indicates that the ability of these joints to conduct material from one system to another can vary widely. Microscopic observations indicate that adventitious roots usually occur on the main root system.
