摘要: 利用1980-2017年富川地面气象观测站的逐日温度、日照时数、相对湿度、降雨等气象资料,通过气候统计分析,结合脐橙生产过程中的调查结果,分析富川县现气候变化与黄龙病发展态势之间的关系。结果表明,富川县38年来的温度变化为柑桔木虱和黄龙病菌孢子的生长提供了良好的温度环境;3月份日照时数的线性增加,有利于柑桔木虱产卵繁殖;年平均相对湿度变化有利于种群数量的增长;6-11月份平均相对湿度变化有利于黄龙病病源生物的存活、繁殖传播;6-11月份、10-12月份降雨量增多间接导致黄龙病传播范围的扩大。

Abstract: The paper aims to study the causes of yellow shoot disease in the navel orange orchards in Fuchuan county of Hezhou city, Guangxi. Based on daily temperature, sunshine hours, relative humidity, rainfall data from the Fuchuan Meteorological Station from 1980 to 2017, by analyzing climate statistics, and survey of the navel orange production process, we studied the correlation between current climate change in Fuchuan and the development trend of the yellow shoot disease. The results showed that the temperature change in Fuchuan in the past 38 years provided a good temperature environment for the growth of Diaphorina citri and yellow shoot disease spores; the linear increase in sunshine hours in March was beneficial to the spawning and propagation of Diaphorina citri; the annual average relative humidity change was conducive to population growth; the change of average relative humidity from June to November was beneficial to the survival and propagation of the yellow shoot disease; the increase of rainfall from June to November and October to December indirectly led to the expansion of the spread of the disease.
