洛阳市苹果主要病虫害风险区划

Risk Zoning of Main Diseases and Pests of Apples in Luoyang City

利用苹果病虫害发生程度的气象预测模型,结合洛阳市1981—2010年日均气温、日均空气相对湿度等地面气象观测资料,建立洛阳市苹果病虫害风险区划,为指导苹果病虫害防治工作提供科学依据。结果表明,栾川苹果斑点落叶病、苹果桃小食心虫偏重发生,偃师、洛宁苹果白粉病发生风险较大,洛宁、宜阳轮纹病发生风险较大。

Based on the average temperature,the daily average air relative humidity and other terrestrial meteorological observation data of Luoyang City from 1981 to 2010 ,the project established the risk zoning of apples＇ diseases and pests in Luoyang City with the forecasting model of the occurrence of apples＇ main diseases and pests, in order to provide scientific basis for guiding the prevention and cure of apples＇ diseases and pests.The results showed that the incidence of apples＇ spotted leaf disease and peaches＇ carposina sasakii were significant in Luanchuan,and the risk of apples＇ powdery mildew occurred in Yanshi and Luoning,the risk of apples＇ rheumatism occurred in Luoning and Yiyang.
