摘要
对福建邵武卫闽国有林场、古田采育场、永安国有林场各光皮桦家系试验林星天牛的危害进行调查。以有虫株率为指标对各家系进行动态聚类分析,结果家系13095、169、125的抗性最强;以有虫株率和生长量为指标对各家系进行动态聚类分析,结果家系137、169、174、13095、125、114属生长优良的抗性家系。家系13095、169、125属生长优良的抗性家系,而家系137、174、114属生长优良的中抗家系,这6个家系可在今后的造林中推广应用。
Damage of Anoplophora chinensis in Betula luminifera was investigated on Weimin state-owned forest farm, Gutian stateowned forest farm and Yingan state-owned forest farm in Fujian Province. Cluster analysis of the attacking rate, indicated that family 13095,169 and 125 had higher resistance to insects. Cluster analysis of attackin rate and growth amount suggested that family 137, 169,174,13095,125 and 114 grew best. On the whole family, 13095,169 and 125 were best in pest resistance and the growth rate, and 137,174 and 114 were moderate. So these 6 families were recommended to plant more.
