摘要：

以小麦茎基腐病病株率做为预报量，小麦播期、11月高于0℃的积温、1-2月份逐日温度之和、3月上中旬逐日温度之和及3月份的雨量做为预报因子，运用模糊综合决策方法建立小麦茎基腐病发生趋势预测模型；药剂防治试验结果表明：50%甲基托布津WP、25%多菌灵WP和50%苯菌灵WP在茎基腐发病初期喷雾，防效均在75%以上。

Abstract:

A forecast model of wheat basal rot was established with in this paper using a method for synthetic decision of Fuzzy Mathematics. The incidence was predicted value. The prognostic factors had time of sowing, accumulated temperature was higher than 0℃ in November, accumulated temperature of January to February, accumulated temperature that the first twenty days of a month March, and rainfall in March. Fungicide treatment results showed that the control effects of thiophanate-methyl 50% WP, carbendazim 25% WP and benomyl 50% WP were all above seventy-five percent when the treatment time in disease primary.
