摘要
通过对巨桉皆伐迹地进行萌芽更新试验,结果表明:巨桉第一代伐桩萌芽率达98.7%,1年生萌芽林树高、胸径分别比同龄实生林提高273.3%、390.0%;4年生树高、胸径、单株材积、蓄积分别比同龄实生林提高18.9%、24.3%、74.7%和54.0%,单位面积、单位蓄积造林更新费用分别仅为同龄实生林的67.6%、43.9%,经济效益明显。
By studying the experiment of the germination of Eucalyptus grandis in this essay, the results showed as follows： the ger- minating rate of the first generation stumping Eucalyptus grandis was 98.7%. The height and dbh of 1-year-old Eucalyptus grandis were 273.3% and 390.0% more than those of the natural forestry of the same kind respectively. The height, dbh, individual-tree volume and stocking of 4-year-old Eucalyptus grandis were respectively 18.9% ,24.3% ,74.7% and 54.0% more than the natural forestry. The afforesting fees per square and per stocking were respectively 67.6% and 43.9% of the natural forestry. Economic effect was apparent.
