山银花主要病虫发生与海拔高度的相关性研究

通过调查不同海拔高度危害山银花植株的胡萝卜微管蚜、白粉病、尺蠖发生程度，探讨山银花主要痛虫发生程度与海拔高度之间的相关性。结果表明，在所调查的海拔高度内，白粉病的病情指数随着海拔高度的升高而增长，4～5月生长在海拔430m地带的山银花植株白粉病发生严重。胡萝卜微管蚜在所调查的各个海拔高度均有分布，1～3月在海拔290—350m之间发生较重，4月在海拔320～430m之间发生较重；5～6月发生逐渐减轻。在夏梢期，山银花尺蠖对叶片的危害随着海拔的升高而减轻。山银花主要病虫发生与其所处的海拔高度存在一定的相关关系，该项调查研究为探索不同海拔高度山银花主要病虫发生规律奠定了基础。

Study on Relationship between Outbreak of Flos lonicerae Diseases and Insects and Altitude

The correlation between the outbreak of Flos lonicerae diseases and insects and altitude was discussed by investigating the damage degree of semiaphis heraclei, powdery mildew and heterolocha jinyinhuaphaga at different altitudes. The results showed that disease index of powdery mildew go up with the increase of altitude, with the worst record occurring at an altitude of 430 m in April and May. As for semiaphis heraclei, they are found at all levels of altitude, with worse damage at altitude 290 - 350 m from January to March and at altitude 320 - 430 m in April. The damage begins to decrease from May and June. In summer shoot period, the damage of heterolocha jinyinhuaphaga to Flos lonicerae leaves alleviates with the rise of altitude. Therefore, the outbreak of Flos lonicerae diseases and insects is related to altitude, and the study laid a foundation for further research on Flos ionicerae diseases and insects.
