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。

摘  要:
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/667m2), high late blight control efficiency(efficiency for disease index82.39%-85.78%),andhighyieldincrease(41.40%-45.49%). These data provide a sound base for guiding late blight control in field.
