摘　　要：本试验以菜豆品种先行者为试材,采用32孔、50孔两种规格穴盘,设置10、15、20、25 d等4个苗龄段,通过研究不同穴盘规格和苗龄对菜豆性状及产量的影响,筛选出适合菜豆育苗的穴盘规格和适宜的苗龄。结果表明:穴盘育苗的营养面积增大,菜豆产量随之增加,25 d苗龄条件下,32孔穴盘的前期产量和总产量均显著高于50孔穴盘;随着苗龄的增长,菜豆的前期产量和总产量呈增加趋势,其中25 d苗龄的产量显著高于其他苗龄。综合上述各项指标,菜豆育苗阶段,10 d苗龄可选用32孔、50孔穴盘,15 d以上秧苗选用32孔穴盘为宜。This paper took the common bean variety Xianxingzhe as the test material, used two kinds of plug sizes(32 holes and 50 holes), set up four seedling age stages(10 d, 15 d, 20 d and 25 d), and screened out the plug size and seedling age suitable for common bean seedling breeding by studying the effects of different plug sizes and seedling age on the character and yield of common bean. The results showed that the yield of common bean increased with the increase of nutrient area;under the condition of 25 d seedling age, the early yield and total yield of 32 holes plug were significantly higher than that of 50 holes plug;with the prolongation of seedling age, the early yield and total yield of common bean showed an increasing trend, and the yield of 25 d seedling age was significantly higher than that of other seedling ages.Based on the above indicators, 32 holes and 50 holes plug could be selected for common bean seedlings at 10 d stage, and32 holes plug was suitable for seedlings above 15 d.
