榕江县松材线虫病气象生存条件及防治建议研究

Study on Meteorological Survival Conditions and Prevention Recommendations for Pine Wilt Disease in Rongjiang County

摘要: 本文主要研究气象因素对松材线虫病的生存条件和危害程度影响，利用2020年至2024年榕江县国家基本气象站及忠诚镇区域自动站气象数据资料和松材线虫病疫情数据，结合对各个气候因子进行统计分析的方法，得出：(1) 古州镇松材线虫病枯死株数变化、危害面积变化整体呈现先增后降再增的趋势，忠诚镇则整体呈现先增后降的趋势；(2) 在高温、降雨少、低湿、干燥的条件下，有利于松材线虫在榕江境内的生存发展；反之则不利于松材线虫的生存发展。因此为有效抑制其爆发，建议可在降雨偏多的夏季(5~7月)及温度较低的冬季(11~次年1月)进行病虫害疫情防控和防治工作。

Abstract: This study primarily investigates the influence of meteorological factors on the survival conditions and severity of Pine Wilt Disease. Utilizing meteorological data from the National Basic Meteorological Station in Rongjiang County and the regional automatic station in Zhongcheng Town from 2020 to 2024, along with epidemic data on Pine Wilt Disease, and employing statistical analysis of various climate factors, the following conclusions were drawn: (1) The number of dead trees and the affected area due to Pine Wilt Disease in Guzhou Town overall exhibited a trend of initial increase, followed by a decrease, and then a subsequent increase, while in Zhongcheng Town, the trend showed an initial increase followed by a decrease. (2) Conditions of high temperature, low rainfall, low humidity, and dryness are conducive to the survival and development of pinewood nematodes within Rongjiang County; conversely, opposite conditions are unfavorable. Therefore, to effectively suppress outbreaks, it is recommended to conduct pest prevention and control efforts during the summer months (May-July) when rainfall is relatively abundant and the winter season (November-January of the following year) when temperatures are lower.
