摘要
采用通过筛选的2个木麻黄抗逆无性系与当地生长较好的惠2无性系进行对比造林试验,4a的试验结果表明:从成活率、保存率和抗病虫害等方面看,2个抗逆无性系都有良好的适应性和抗逆性;2块木麻黄试验林各年调查的树高、地径、胸径、材积等性状进行的方差分析大都达到显著或极显著水平,无论是1号样地还是2号样地,抗逆无性系在各个生长性状上都优于对照,这说明了选择出来的抗逆无性系具有较高的推广价值。
Comparative forestation experiments were conducted between 2 Casuarina equisefolia clones with disease-resistance and pest-resistance which were screened out and Hui 2 clones.Four years experiments showed that 2 clones with disease-resistance and pest-resistance both had optimal adaptability and resistance.Variance analysis which was conducted by investigation about tree height and ground diameter and DBH and volume of 2 test plots of Casuarina equisefolia reached significance level or extreme significance level. Whether No.1 site or No.2 site, the clones with resistance on every growth characteristics were superior than the check. It illustrated that clones with resistance had higher spreading value.
