| 摘 要： | 本文用环割法模拟萧氏松茎象危害幼树，连续观测幼树的生长状况。结果表明，模拟环割对湿地松树高生长的影响较大，环割90％相对生长百分率最小，仅有17％，显著小于对照的28％。对胸径和地径生长均有一定的影响；但差异不显著。环割90％的湿地松胸径和地径相对生长百分率最小，分别为22％和34％，小于对照的25％和43％。连续危害对湿地松生长影响更大。地径第1年的相对生长百分率平均达到了40％，第2年的约25％左右。树高第1年相对生长百分率平均大于16％，第2年的相对生长百分率不足10％。 |

| Abstract: | Hylobitelus xiaoi was a new outbreak pest in south of China. To study the growth responses of young slash pines harmed by Hylobitelus xiaoi Zhang,this paper simulated harmfulness of the pests by girdling. The results showed that the relative growth of height of the slash pines was only 17% one year,which was girdled 90%,less than CK. And the relative growth of diameter at breast height (DBH) and diameter at ground were 22% and 34%,which was girdled 90%,less than CK too. The growth of height and ground diame... |
