摘　　要：为提高芝麻杂交制种生产效率,实现机械化作业,于2016-2019年在安徽省临泉县、新疆精河县等地,围绕亲本组合选配、播期、父母本行比配置、水肥管理等开展相关试验。结果表明,亲本组合配对中,以WA18073×皖芝2181的产量最高,比其他组合平均产量提高28.65%;18万株/hm^(2)密度处理较为适宜;春播有利于提高制种产量,比夏播增产36.29%;父母本行比以1∶3处理较合理。参考试验结果并结合生产实际,提出了芝麻杂交制种机械化生产技术要点。In order to improve the efficiency of sesame hybrid seed production and realize mechanization,we carried out relevant experiments in Linquan County of Anhui Province,Jinghe County of Xinjiang and other places in 2016-2019.The parent combination selection,sowing date,parent row ratio,water and fertilizer management were mainly researched.Results showed that the highest yield was the parent combination WA18073×Wanzhi 2181,which was 28.65%higher than the average yield of other combinations.The density of 180000 plants/hm^(2)was more appropriate.The yield of spring sowing was 36.29%higher than that of summer sowing,and the more reasonable ratio of parents to lines was 1∶3.According to the experimental results and the production practice,the key points of mechanized production technology of sesame hybrid seed production were put forward.
