山西省小麦条锈病常发区中期测报技术研究

Study on the Medium-term Forecast of Wheat Stripe Rust in Shanxi

通过对芮城县小麦条锈病13年历史资料的研究分析,初步明确了决定病害发生程度的主要因素是感病品种面积占总麦田的比率、4月份温雨系数及5月上旬降雨量。同时组建了该病害发生程度的中期预测模式。

Based on analysis of the epidemic condition of Wheat stripe rust（Puccinia striiformis west） in Ruicheng county of the past 14 years,the major influential factors of the disease epidemic degree were determined in the paper , which are sus-ceptible area ratio, the temperature coefficient in April and the rainfall of early May. At the mean time the paper sets up a me- dium range forecast model of wheat stripe rust in Shanxi province.
