摘要
选择桉树枝瘿姬小蜂(Leptocybe invasa Fisher&La Salle)高感品系巨园桉(Eucalyptus grandis×E.tereticornis)DH201-2,研究其受桉树枝瘿姬小蜂危害后在近自然条件下生长情况。结果表明:连续5年内树高、胸径和材积保持生长,5年生林分平均树高、胸径和材积生长量分别达到12.9 m、8.4 cm和57.31847 m3/hm2。
Eucalyptus grandis x E. tereticornis DH201-2, a highly susceptible species of Euca- lyptus to Leptocybe invasa Fisher ＆ La Salle was selected to study the plantation growth under the approx-natural conditions after being attacked by the pest. The results showed that the plantation kept growing in height, diameter at breast height and volume for 5 consecutive years. The average height, diameter at breast height and volume of the 5-year old plantation reached 12.9 m, 8.4 cm and 57.31847m3/hm2 respectively.
