东坡区川芎根腐病发病气象因子及防治对策研究

Study on Meteorological Factors and Control Measures of Rhizome Rot of Ligusticum Chuanxiong in Dongpo District

摘要: 川芎根腐病是四川川芎生产上的主要病害之一，每年均有不同程度地发生，近几年来，且呈逐年加重趋势，给川芎产量造成了巨大影响。现阶段研究发现：气象条件、根腐菌源是影响根腐病发生程度的主要因素。据调查：气象条件是影响或左右川芎根腐病发生、消长和危害的最直接生态环境因素，二者关系甚为密切。因此研究川芎根腐病发生流行与气象条件的关系、发生流行的气象环境成因、气象预测预报，不断提高对病害预测预报技术水平，对于川芎根腐病的防治有着积极作用。

Abstract: Rhizome rot of Ligusticum chuanxiong is one of the main diseases in the production of Ligusticum chuanxiong in Sichuan province. It occurs to varying degrees every year. In recent years, it shows an increasing trend year by year, which has a great impact on the yield of ligusticum chuanxiong. At present, it is found that meteorological conditions and root rot source are the main factors affecting the occurrence degree of root rot. According to the investigation, meteorological conditions are the most direct ecological environmental factors that affect the occurrence, fluctuation and harm of rhizome rot of Ligusticum chuanxiong, and the two are closely related. Therefore, the study on the relationship between the occurrence and epidemic of rhizome rot of Ligusticum chuanxiong and meteorological conditions, the cause of the occurrence of epidemic meteorological environment, and the meteorological prediction and forecast will constantly improve the technical level of disease prediction and forecast, which will play a positive role in the prevention and control of rhizome rot of Ligusticum chuanxiong.
