摘　　要：[目的]寻找对楚大麦610赤霉病有较好防效的药剂和喷药时期。[方法]设置药剂种类(A)和喷药时期(B)2个因素,各设3个水平,对楚大麦610进行赤霉病防治,于蜡熟期调查其病情指数和防治效果,成熟期调查其产量和增产率。[结果]4个指标数据处理结果相似,2因素间互作效应不显著,因素A间没有显著差异,因素B间有极显著差异,防治效果越好产量越高。对楚大麦610赤霉病防治的关键是喷药时期,以初花期进行防治效果最佳,抽穗期次之,终花期最差。[结论]初花期对楚大麦610进行赤霉病的药剂防治效果最佳,且应隔期进行不同种类药剂的轮换使用,避免赤霉病菌对药剂产生抗性及交互抗性。In order to find a better scab control efficacy of pharmaceutical and spraying period of the ＂Chu Barley 610＂,the experiment set type and amount of agents（A） and the spraying period（B） two factors,each with three levels.The results showed： the results of the four indicators of data processing is similar,interaction between the two factors was not significant.A factor was no significant difference between different levels,diffenent levels of factor B was significant difference,the better control effect the higher yield,we survey its disease index and control effect on the dough stage,increase the yield and yield on maturity stage.So,for prevention and treatment of the barley scab,the key is spraying period,the early flowering stage to control is the best.
