| 摘要：为了增加瑞绿6号的制种产量及种子纯度，研究了不同定植密度（每667 m2分别定植2 000、2 200、2 400、2 600株）和不同定植方法（隔株、隔行、隔垄）对瑞绿6号制种的影响。结果表明：青花菜瑞绿6号制种中，父母本应该严格采用隔株定植；每667 m2定植2 400～2 600株最为合适，每667 m2制种产量为25.7～25.9 kg，且种子纯度大于96%。 |

| Abstract: In order to increase seed yield and purity of 'Ruilü No.6', different planting densities (2 000, 2 200, 2 400, 2 600 plants per 667 m2) and methods ( plants alternation, rows alternation, ridge alternation) were used to study the different effects on seed production of 'Ruilü No.6'. The results showed that in the seed production of 'Ruilü No.6', parents should strictly adopt plants alternation, and 2 400 to 2 600 plants per 667 m2 were the most suitable density, whose yield was from 25.7 kg to 25.9 kg per 667 m2 and the seed purity was more than 96%. |
