摘要
黄泛平原农区是我国杨树的主要栽培区,杨树细菌性溃疡病是该地区发生的一种新病害,研究该区域病害的发生规律及开展病害风险评估十分重要和必要.本文应用定点定时观察方法,研究病害发生规律;参照有害生物风险分析方法,进行病害综合风险评估.研究结果表明,该病害每年4~10月份发生,在菏泽及黄泛平原农区风险R值为2.105,属高度危险性有害生物.
The agricultural area of the Yellow River flood plain is the main cultivation area of poplars in China.The bacterial canker of poplar(Lonsdalea quercina subsp.populi)is a new disease occurring in this area.It is very important and necessary to study the occurrence regularity of the disease and carry out disease risk assessment.This paper studies the regularity of disease occurrence by fixed point and fixed time observation,and refers to pest risk analysis method to conduct comprehensive disease risk assessment.The results show that the disease occurs from April to October every year,and the risk R-value is 2.105 in Heze and Yellow River flood plain agricultural areas,which is a highly dangerous pest.
