小麦赤霉病自动监测预警系统应用效果评价

Application effect evaluation of the automatic monitoring and warning system for Fusarium head blight

2018年在江苏、陕西、河南、湖北、安徽共18个县(市)安装了小麦赤霉病预报器,在周边设置未防治麦田进行赤霉病调查,并与预警软件平台预测结果相比较,评价小麦赤霉自动监测预警系统的准确性。评价结果表明,2018年该系统预测的准确性达71.8%。结合陕西省植保总站、西安市植保站、渭南华州区植保站、商洛洛南县植保站、安徽凤台县植保站2016年-2018年对该系统的评价结果,证实该系统预测准确性较高,系统工作稳定,自动化程度高,可为小麦赤霉病的科学防控提供重要的参考依据,具有一定的应用前景。

In 2018, we installed 18 predictors in Jiangsu, Shaanxi, Henan, Hubei and Anhui to evaluate the prediction accuracy of the system. The prediction results from the system were compared with that achieved from the investigation in un-control fields. Results showed that prediction accuracy of the system reached to 71.8% in 2018. Combined with the evaluation results from Shaanxi Provincial Plant Protection Extension Station, Xi’an Provincial Plant Protection Extension Station, Huazhou Plant Protection Extension Station in Shaanxi, Luonan Plant Protection Extension Station in Shaanxi and Fengtai Plant Protection Extension Station in Anhui, the accuracy of the system was high, and the system was stable, reliable with high automation level and good application prospect, which can provide important reference for controlling the disease.
