摘　　要：为明确不同育苗方式对酿酒高粱主要农艺性状和产量的影响,选用高粱品种宜糯红8号为试验材料,于2022—2023年对高粱幼苗发育进程、性状及产量构成因素进行比较分析。结果表明,采取传统撒播育苗方式,高粱的幼苗根数均高于其他育苗方式。在漂浮育苗方式下,高粱的百苗重和出苗率均高于其他处理。传统撒播育苗方式延长了播种至移栽期和全生育期,缩短了移栽至抽穗期,产量最低。采用漂浮育苗方式或通过提高穗重获得高产。高粱产量与播种至移栽期天数呈极显著负相关,相关系数为-0.93。因此,结合各地高粱生产需求,因地制宜,推荐采用漂浮育苗方式效果最佳。In order to clarify the effects of different seedling cultivation methods on the main agronomic traits and yield of winemaking sorghum,the sorghum variety Yinuohong 8 was selected as the experimental material,and the development process,traits and yield components of sorghum seedlings were compared and analyzed from 2022 to 2023.The results showed that the root number of seedlings in sorghum was higher in traditional sowing method than that of other seedling cultivation methods.Under the floating seedling cultivation method,the hundred-seedling weight and seedling emergence rate of sorghum were higher than those of other treatments.The traditional sowing method extended the sowing-transplanting period and the whole growth period,shortened the period from transplanting to heading stage,and had the lowest yield.The floating seedling cultivation method can achieve high yield by increasing the panicle weight.There was a significantly negative correlation between sorghum yield and the number of days in the sowing-transplanting period,and the correlation coefficient was-0.93.Therefore,combined with the production needs of sorghum in various places and according to local conditions,it is recommended to use floating seedling cultivation method for the best effect.
