| 摘要: |
| 在 2002—2016 年对广东省部分重要林木病害进行现场调查，分析气流与林木侵染性病害
发生之间的关系。结果表明，在广东省广泛发生的黎蒴（Castanopsis fissa）枝枯病和桉树（Eucalyptus
sp.）梢枯病属于气传病害；气流运动为杉木（Cunninghamia lanceolata）细菌性叶枯病、红豆杉（Taxus
chinensis）根腐病、相思（Acacia sp.）根腐病和木麻黄（Casuarina equisetifolia）青枯病病原菌开辟了入
侵通道；这些病害的防治策略可进行相应调整。气流运动导致广东省部分重要林木病害的发生，建议开
展针对气传病害的试验研究来推动今后的防控工作。 |

| Abstract: |
| In 2002-2016, some important forest diseases in Guangdong province were investigated in the
field, and the relationship between airflow and infection diseases of forest was analyzed according to the survey
data. Results showed that branch withering of Castanopsis fissa, dieback of Eucalyptus sp. were caused by the air
borne diseases; the airflow opened up the invasion channel for pathogen of bacterial leaf blight of Cunninghamia
lanceolata,root rot of Taxus chinensis, Acacia sp. and bacterial wilt of Casuarina equisetifolia; the penetration and
control strategies for these diseases could be adjusted accordingly. In summary, airflow could obviously make for
the occurrence of some important forest diseases, it was recommended to carry out the experimental study of air
borne diseases to promote the future prevention and control work in Guangdong province. |
