摘要(Abstract)：

【目的】摸索冰糖橙溃疡病田间发病规律,根据冰糖橙物候期和气象因素建立预测方程,预测溃疡病的发生,指导溃疡病的及时防控。【方法】在冰糖橙果园安装Vantage Pro2型自动气象观测仪对主要气象因子进行定期监测,结合观察冰糖橙物候期和调查田间新梢、幼果溃疡病发病动态情况,建立溃疡病发病的预测方程。【结果】连续2年的观察结果表明,溃疡病发病与冰糖橙物候期、果园气象因子密切相关,枝梢溃疡病初发病时间均在叶片达到最大面积前后,果实初发病时间在第1次生理落果结束时。枝梢溃疡病发病前期都出现一定时期的高温、大风、降雨天气,果实的发病与降雨量、气温、平均风速、相对湿度等气象因子密切相关;比较春梢、夏梢、秋梢的最终病情指数发现,春梢感病最重、夏梢次之、秋梢最轻。【结论】对2011年与2012年春、夏梢萌芽后连续每5 d的平均温度及春、夏梢距初发病天数进行了双变量相关性分析,发现萌芽后每5 d的平均温度与距离第1次表现症状的时间呈显著负相关,根据其相关性构建了预测方程,为病害防控提供参考依据。
