自一九六五年以来,渡口地区先后引进桉树已达七种之多,其中以赤桉生长最好。它不仅抗旱性强,而且在渡口干热气候条件下四季不停止生长。房前屋后栽植的赤桉,好的六年生高达23米,胸径35厘米,一般4—5年生叩可成材。是渡口地区四旁绿化较好的一种速生用材树种。但赤桉用于荒山成片造林,还是一个值得探索的问题。 Since 1965, the area has introduced eucalyptus has reached as many as seven species, of which Eucalyptus grow best. It is not only drought-resistant, but also does not stop growing in the seasons under dry and hot ferry conditions. Eucalyptus planted in front of the house, a good six-year-old up to 23 meters, diameter 35 cm, usually 4-5 years percussion can become useful. It is a kind of quick-growing afforestation species with greening around the ferry area. However, Eucalyptus is used in afforestation of barren hills, and it is still a question worth exploring.
