摘要
为摸清松材线虫病死树发生规律,本研究采用远程监测的方法分析了近年来九峰地区的枯死树变化情况,对感病松树的发生位置、发生数量及外观特征变化进行了分析。结果表明:(1)九峰地区的感病松树多发生在马驿峰和宝盖峰;(2)感病松树的显症时期多为夏秋两季;(3)感病松树被初次观测到的外观症状多表现为多数针叶变黄,植株开始萎蔫。
In order to understand the occurrence pattern of dead pine nematode trees,this study analyzed the changes of dead trees in Jjiufeng area in the past two years by remote monitoring,and analyzed the location,number and appearance characteristics of disease-susceptible pine trees.The results showed that:①most of the susceptible pine trees in Jiufeng area occurred in Mayi Peak and Baogai Peak;②most of the susceptible pine trees showed symptoms in summer and autumn;③most of the susceptible pine trees showed yellowing of most of the needles and wilting of the plants when they were first observed.
