马铃薯晚疫病预警技术发展历史与现状

本文系统介绍了国内外马铃薯晚疫病预警技术的发展历史和应用现状。马铃薯晚疫病预警技术的发展大体经历了三个阶段,第一阶段是基于一定气象条件规则的人工预警方法;第二阶段是基于预测模型的电算预警技术;第三阶段是基于田间病害监测和信息技术的监测预警系统。目前,一些发达国家特别是欧洲主要应用监测预警系统。我国也已组建了"中国马铃薯晚疫病监测预警系统",并已实现网上运行和服务(其域名为:www.china-blight.ne)t,该系统的进一步推广应用,将为我国马铃薯晚疫病监测预警和有效防控提供有力保障。

Historial and Current Situation of Warning Techniques on Potato Late Blight

The historial and current situation of the development of warning techniques on potato late blight was reviewed in this paper.The development of warning techniques on potato late blight could be divided into three stages.The artificial warning methods based on certain meteorological rules were used in the first stage;the computerized warning techniques based on forecast models were developed and utilized in the second stage;and in the third stage monitoring and warning systems based on disease monitoring in the field as well as the information techniques have been widely used today.At present,the monitoring and warning systems are mainly used in the developed countries especially in Europe."The monitoring and warning systems on potato late blight of China" has been constructed in our country,and has been running and servicing on Internet(the domain name is: www.china-blight.net).With the further popularizing of this system,the monitoring,warning and effective control against potato late blight in our country will be firmly supported.
