摘　　要：笔者调查了近年来危害黄土高原丘陵区红枣的主要病虫害种类,总结了黄土高原丘陵区5种枣树主要病虫害暴发流行的气象条件,建立了枣锈病和枣桃小食心虫的气候预测模型。用佳县近34年的气象观测资料对模型进行检验。结果显示:2个预测模型计算的发病指数所指示的不同等级病虫害发生概率与实际基本相符;典型灾害年份指数值大小分布与实际灾情轻重程度吻合。所建2种病虫害预测模型可用来预测黄土高原枣区2种主要病虫害的暴发流行程度,为防灾减灾工作的及时部署和开展提供参考依据。In this paper, the main diseases and insect pests of jujube in hilly region of loess plateau in recentyears were investigated. The meteorological conditions for the epidemic outbreak of 5 kinds of jujube’sdiseases and insect pests in this region were summarized. The climate prediction models of jujube rust andjujube Carposina niponensis were established. The authors used the meteorological observation data of Jiaxianin nearly 34 years to test the models. The results showed that the occurrence probabilities of different levels ofdiseases and insect pests as indicated by the two prediction models were consistent with the actual situation;the numerical value distribution of typical disaster years coincided with the actual degree of the disaster. Thetwo models can be used to predict the outbreak of two major diseases and insect pests in the loess plateau, andprovide reference for the timely deployment and implementation of disaster prevention and mitigation.
