| 中文摘要: |
| 近年来，柑橘黄龙病在桂东北柑橘产区呈高发状态。该文通过对2008～2015年1～2月、5～7月和10～11月3个时期气象资料的统计分析，探索柑橘黄龙病发生蔓延的气象条件。结果显示，2009、2010年和2013～2015年5年为暖冬气候。特别是2013～2015年间，1～2月连续3年为暖冬气候、5～7月的南风大到暴雨次数达7次、10～11月平均温度仍处于柑橘新梢抽发的适宜值范围。为柑橘黄龙病传病媒介—柑橘木虱的越冬、迁移、增加食源创造了有利条件。因此，建议柑橘产区抓好1～2月、5～7月和10～11月这3个关键时期柑橘木虱的统防统治工作，控制柑橘黄龙病的传播蔓延。 |
| 英文摘要: |
| The incidence of Citrus Huanglongbing was high in northeastern Guangxi in last several years. In order to reveal meteorological conditions suitable for the prevalence of Citrus Huanglongbing, meteorological documents of three periods, including January to February, May to July and October to November of 2008 to 2015, were statistically analyzed. The results showed that the winter of five years, including 2009, 2010, 2013, 2014 and 2015, was warm. Especially during the period from 2013 to 2015, the temperature during January and February was relatively high, the events of huge south wind combined with rainstorm could reach up to seven times, and both temperature and rainfall during October and November were in the range suitable for the flushing of citrus. These meteorological conditions were advantageous for the hibernation, migration and increasing food resource of psyllids, the transmission vector of Citrus Huanglongbing. Consequently, large-scale controls of citrus psyllids during the above three periods should be performed timely and strictly. |
