摘要
依据比利时马铃薯晚疫病预警系统模型预测,确定马铃薯主要生育期内,病菌生成潜在侵染次数、代数和最佳防治期及防治次数,运用多目标决策方法,通过对西吉县‘青薯9号’品种马铃薯晚疫病田间药剂防治试验进行决策分析,获得了防治成本低（46.5-49.5元/667m2）、防治效果高（病指防效82.39%-85.78%）和保产效果好（41.40%-45.49%）的综合效益决策矩阵及决策靶,为指导马铃薯晚疫病田间防治提供了科学依据。
Based on a Belgium Warning System against Potato Late Blight, potential infection number, generation of Phytophora infestans de Bary, and optimal spray time and number of spray were determined using a multi-objective decision method. Based on the analysis on a field trial for late blight control of ＇Qingshu 9＇ in Xiji County, decision-making matrix and target were established for low cost （46.5-49.5 Yuan/667m^2）, high late blight control efficiency （efficiency for disease index 82.39%-85.78%）,andhighyieldincrease （41.40%-45.49%）. These data provide a sound base for guiding late blight control in field.
