摘要
采用标准地和历史资料相结合的调查方法对广西油茶病虫害发生情况进行调查统计分析,到2014年,广西油茶病虫害249种,其中,油茶害虫191种,病害58种。采用灰色系统模型和马尔可夫链方法进行预测,预计到2025年,广西油茶病虫害种类将增加到300种,年度严重危害面积将达到6 000 hm2。建议采用适地适树、科学规划、良种壮苗、加强监测、推广生物防治等措施控制油茶病虫害。

The pests were 191 species and diseases were 58 species. The development trend of Camellia pests and diseases in Guangxi in 2025 was estimated by Gray Method and Markov Chain. The result showed that pests and diseases would be 300 species and the damage area would be 6 000 hm2. In order to control Camellia pests and diseases efficiently, the considerable measures should be as follows： according to the local environment selecting specific Camellia species, making Camellia development plan scientifically, selecting fine seedlings, strengthening pest inspection and promoting biological control.
