| 摘 要： | 大量资料统计分析表明,橡胶树白粉病的流行,是按指数增长、逻辑斯蒂生长模型增长、衰退等过程发展的。这为准确描述和预测病害的发展提供了新的理论依据。海南地区橡胶树白粉病流行结构分析表明,在南部和东部,物候期的长短和越冬菌量对流行影响最大;而在西部则以物候期的长短和流行速度最为重要。据此,提出了这些地区的防治策略。

| Abstract: | Analytical results of epidemiological data showed that the epidemic course of Oidium heveae has three phases, i. e. exponential phase, logistic phase and disease abating phase. It was found from the analysis of the epidemic structure that the length of the phenological period and the amount of hibernating inoculum exercised the strongest influence on the epidemic of the disease in south and east Hainan Island, while the length of the phenological period and disease rate were the most important factors in the west of the Island. Thus control strategies are suggested. |
