| 摘 要： | 2008年11月至2010年1月对广西宁明县和龙州县共74.3 hm2受桉树枝瘿姬小蜂（Leptocybe invasa Fisher & La Salle）危害严重的巨园桉（Eucalyptus grandis × E. tereticornis）DH201-2林分进行更新改造，结果新林分不再受桉树枝瘿姬小蜂危害，定植9个月后2个地点林木平均生长量分别为树高4.0m和3.5m、胸径3.9cm和3.3cm，证明所采用的技术可行，即砍伐受害林木实现有效清除桉树枝瘿姬小蜂虫源、挖除伐根防止产生萌芽条为桉树枝瘿姬小蜂繁衍提供寄主、选择对桉树枝瘿姬小蜂高抗品种尾巨桉（Eucalyptus urophylla × E. grandis）DH32-29作更新造林树种、采用勾机挖坑、适时定植、及时抚育和施肥等科学营林措施促进林木快速生长等。试验发现受害林分更新改造还促进周边非易感桉树枝瘿姬小蜂但已受其影响的巨尾桉（Eucalyptus grandis × E. urophylla）GL9恢复生长，提出受害林分更新改造应作为我国当前防控桉树枝瘿姬小蜂的重要措施。 |

| Abstract: | Experimental alteration of Eucalyptus grandis × E. tereticornis DH201-2 plantation totally 74.3 hm2 severely attacked byLeptocybe invasa Fisher La Salle in Ningming and Longzhou of Guangxi was carried out from November 2008 to January 2010, results showed that the replanted plantations were not attacked byLeptocybe invasa Fisher La Salle, forests average height reach 4.0 m and 3.5 m, average diameter at breast height get to 3.9 cm and 3.3 cm respectively in two places 9 months after replanting, technologies utilized were proved to be effective, which were clearcutting of infected trees to kill the existing Leptocybe invasa Fisher La Salle; digging up the stumps to stop supplyingLeptocybe invasa Fisher La Salle with host sprouting from the stumps; selection of replanted species ofEucalyptus urophylla ×E. grandis DH32-29 with high resistance toLeptocybe invasa Fisher La Salle; advanced silvicultural measures such as digging planting holes with digging machine, planting in favourable season, tending and fertilizing in time etc. to accelerate the forest growth. The experiment also indicated that alteration of infected forest could recover the plantation ofEucalyptus grandis ×E. urophylla GL9 nearby, which was not easily infectious to but affected by Leptocybe invasa Fisher La Salle. Alteration of forest attacked byLeptocybe invasa Fisher La Salle was pointed out to be an important measure for controllingLeptocybe invasa Fisher La Salle in China currently. |
