葡萄霜霉病预测模型及预警技术研究进展

霜霉病是危害葡萄最严重的病害之一,目前采用的主要防治手段是喷施化学农药,但其用量过多也带来许多严重问题。若要减轻农药污染,就必须对病害进行精确的预测预报,以便确定最合理的农药使用时机和使用量。在此,从病害流行系统的监测、因子选择、结构及应用等方面综述了利用农业气象模型预测葡萄霜霉病的研究应用进展,并对其存在的问题及发展前景作了讨论。

progress in Prediction Model and Warning Technology of Grape Downy Mildew

Downy mildew is one of the most serious grape diseases,the usual treatment method presently is the application of chemical fungicide,but excessive spray brings many severe problems. In order to solve the pollution of fungicide,accurate prediction and warning technology must be developed, accordingly the most appropriate occasion and amount of spray can be determined. In this paper, research progress, including epidemic system monitoring of disease, factor selection, structure and application of agrometeorological model in prediction of grape downy mildew is presented, and its problems and prospect were also discussed.
