通过在德化县2003年引种桉种树种造林幼林抚育的试验,在调查试验区(德化县A区、B区、C区)采用随机区组设计,对桉树幼林进行了3种抚育方式试验:①全面劈草;②全面劈草,局部松培土;③全面锄草施肥。试验结果表明,抚育方式的不同对桉树幼林的胸径和树高生长均有显著影响。做好幼林桉树抚育管理,有利于促进林木生长,提高林分生物量和生产力,以充分发挥桉树的速生丰产特性,提高短周期人工林经营的经济效益。为今后推广桉树造林选择合适的幼林抚育方式。
Through the experiment of tending young trees in Eucalyptus species introduced in Dehua County in 2003, three kinds of tending methods were used to test the young eucalyptus trees in randomized block design in the investigated and experimented areas (A, B and C in Dehua County) : ① comprehensive chopping grass; ② a comprehensive chopping grass, local pine soil; ③ a comprehensive weeding fertilization. The results showed that different ways of tending had significant effects on the DBH and tree height growth of young Eucalyptus. Doing tending and management of young forest eucalyptus is good for promoting the growth of forest and improving the stand biomass and productivity so as to give full play to the fast-growing and high yield characteristics of eucalyptus and improve the economic benefits of short-period plantation management. For the future promotion of eucalyptus afforestation choose the appropriate young forest tending methods.
