东北玉米低温冷害远程诊断系统设计与初步应用

针对目前东北地区较易发生玉米低温冷害、不易诊断、数据获取时效性差、诊断参数代表性差等不足,研究构建一个准确、便捷的玉米低温冷害监控与远程诊断系统。通过总结东北地区玉米低温冷害领域专家的经验,结合多年的历史气象资料,对初终霜日期进行宏观预测,根据田间观测的适时环境参数对低温冷害作出及时准确判断和预测。在玉米灌浆期对该系统进行了验证和应用,得到很好的预期效果。初步构建了一个基于Web技术的玉米低温冷害远程诊断与管理系统,为玉米低温灾害的监控和诊断提供了准确、及时、便捷的途径。

Design of Remote Diagnosis and Management System for Maize Chilling Damage and Primary Application in Northeast China

Based on the maize chilling damage of Northeast China with characters such as high frequency, hard to diagnose, freshness was badly, the existed management systems were too complex and parameters were unstable. Assure to set up an accurate and convenient diagnosis system for maize chilling damages. Summarized the experts knowledge and experience about northeast China maize chilling damages, combined with climateological data for many years to forecast the first frost day and the latest frost day, according to the timely environment parameters detected in the field by the management system to diagnose and forecast the chilling damages. The manage system was used and tested when maize in milk, and get a expected effect. We primarily designed a web-based remote diagnosis and management system platform for maize chilling damage. The results indicated that remote diagnosis and management system for maize chilling damage provide an accurate, timely and convenient method for maize production in large scale.
