摘　　要：[目的]筛选在安徽省庐江地区单季稻最适宜的毯状苗机插株距。[方法]采取工厂化培育毯状秧,株距按照插秧机固定参数设11、14、17 cm 3个处理水平,研究3种株距对水稻产量及其构成性状的影响。[结果]11 cm株距有效穗数显著大于另外2个处理,理论产量也最高;在穗粒结构上,17 cm株距穗总粒数最高。[结论]11 cm株距能营造较为合理的基本苗数、发育进程和合理的穗粒构成,适宜在庐江地区作机插一季稻株距配置。[Objective]The aim of this study was to screen the most suitable planting spacing of blanket seedling for single cropping rice in Lujiang area of Anhui province.[Method]The industrial cultivation of blanket seedlings was taken as the experimental object,according to the fixed parameters of transplanter,three plant spacing levels of 11,14 and 17 cm were set to study the effects of three plant spacings on rice yield and its component traits.[Result]The effective panicle number of 11 cm plant spacing was significantly greater than the other two treatments,and the theoretical yield was the highest.In grain structure,17 cm plant had the highest total grain number.[Conclusion]11 cm plant spacing can create more reasonable basic seedling number,development process and reasonable panicle grain composition,which is suitable for planting oneseason rice in Lujiang area.
