| 摘 要： | 通过对板栗膏药病与有关因素关系的调查发现:板栗品种、树龄、地形、蚧虫数量等因素对病害的发生有着重要影响,在不同品种中,粘底板感病最轻,感病指数为32．2％,而浅刺二水早感病最重,感病指数达88．9％;在不同树龄中,4年生以下的板栗膏药病发生程度较轻,感病指数为7．8％-17．7％,而13-20年生的板栗感病较重,感病指数高达88．9％;在不同地形中,山洼栗园感病较重,感病指数为49．23％,而山坡上感病较轻,感病指数为41．2％。此外,还研究了林分密度、管理方式等因素与板栗膏药病发生的相关性,该研究结果可为膏药病的科学、有效防治提供理论指导。

| Abstract: | The relationship between plaster disease and some factors were investigated, and the results showed that the factors including varieties and ages of Castanea mollissima, topography, scales population, and so on, had great effect on the occurring of plaster disease. Among varieties, Zhandiban had higher resistance with 32. 2% infected index, and Qianci-Er-Shui-Zao was the most susceptible with 88. 9% infected index. The infection level of the trees under 4 years old was relatively lower, which was 7. 8%-17. 7%, and that of the tree of 13-20 years old was higher, which was up to 88. 9%. The infected index of the trees in valley was higher than that on slope, and they were 49. 23% and 41. 2% respectively. In addition, other factors relating to plaster disease, such as the density of forest stand and management methods, were also studied. These results could offer scientific and effective theory guidance for controlling plaster disease. |
