两种备耕方式下桉树萌芽林前期长势对比研究

Comparative Analysis of Eucalyptus Germinating Forest Growth in the Early Stage Under Two Cultivation Methods

通过对比炼山和扒带两种备耕方式对桉树萌芽林前期长势的影响,对桉树的树高和胸径进行了测量记录。结果表明:在扒带条件下桉树的树高和胸径的增长显著大于炼山条件,从平均增长量来看,炼山条件下的桉树长势较为平稳,呈逐渐上升趋势,而扒带条件下的桉树树高和胸径平均增长量波动较大。统计对比了桉树的树高和胸径增长,分析了炼山和扒带条件下桉树萌芽林前期的长势情况,并对两种方式产生的影响给出了结论。

By comparing the effects of these two approaches of woodland with control burning and weeded woodland on coppice sprouts of Eucalyptus robusta growth in the early growth stage,the height and diameter at breast height of eucalyptus were measured and recorded.The results showed that the growth of height and DBH of Eucalyptus under the condition of weeded woodland is significantly greater than that of burning.In terms of the average growth,the growth of Eucalyptus under the condition of burning is relatively stable,showing a gradual upward trend,while the average growth of Eucalyptus height and DBH under the condition of weeded woodland fluctuates greatly.Through the statistical comparison of the growth of eucalyptus tree height and DBH,this paper analyzed the growth situation of Eucalyptus in the early stage under the conditions of woodland with control burning and weeded woodland,and discussed the influence of the two methods.
