| 摘 要： | 目的]研究连栽对尾巨桉人工林生长量的影响。方法]对尾巨桉连栽林分和对照林分（第1代）的胸径、树高、蓄积量进行了比较。结果]尾巨桉连栽林分的胸径、树高和蓄积生长量与对照林分相比,并没有表现出下降趋势,其蓄积生长量反而有所增加,但其连年生长量呈下降趋势,出现了早衰现象。结论]连栽使尾巨桉人工林蓄积生长量增加,连年生长量下降。 |
| 关 键 词： | 连栽 尾巨桉 林分生长量 |

| Abstract: | Objective] The aim was to understand the effects of continuous cropping on growth amount of Eucalyptus urophylla×E.grandis plantation.Method] The test comparative research with the DBH,tree height,growing stock of the Eucalyptus urophylla×E.grandis stand between continuous cropping with control(1st generation)was conducted.Result] The DBH,tree height and growing stock of Eucalyptus urophylla×E.grandis increased constantly with the increasing of stand ages.The growth amount of DBH,tree height,growing stock of continuous cropping stand compared with control stand didn't decrease,even the growth of growing stock increased,but the annual growth amount declined,and the phenomenon of premature appeared.Conclusion] Continuous cropping made the Eucalyptus urophylla×E.grandis plantation growing stock increase and the annual growth amount decline. |
