| 中文摘要: |
| 龙眼红粉病是由粉红单端孢菌Trichothecium roseum Link引起，是海南省龙眼主产区龙眼果实生长期新发生病害,该病害在海南发生较普遍。本文利用6种空间分布型聚集度指标、Iwao M*-m回归方程检测和Taylor幂法则对龙眼红粉病空间分布型进行分析，并进行了聚集原因的分析。结果表明：龙眼红粉病发病期病株垂直分布下，有7个田块属聚集分布，第8个田块属均匀分布；水平方向上，病株上部、中部、下部，均为聚集分布，该结果为该病害的有效防治提供理论依据。 |
| 英文摘要: |
| Trichothecium roseum Linkis the pathogenic fungi that causes pink disease of longan, which occurs in Hainan commonly. Its spatial distribution pattern has been investigated in accordance with 6 spatial distribution patterns of aggregate indices and M*-m regression. The results suggested that, during the occurrence period of longan disease, 1st-7th plot showed aggregated distribution while the 8this uniform distribution under vertical distribution. The affected plants in all survey plots showed aggregated distributionin upper, central and lower part under horizontal direction. These findings will provide theoretical basis for the effective prevention and treatment of the disease. |
