| 摘 要： | 为探讨烟田油菜免耕适宜密度,以行距为固定的烟垄行、穴距为33.33 cm,穴定植留苗2株、3株、4株、5株4种不同定植密度,进行了烟田油菜免耕直播试验研究.结果表明,烟田油菜免耕直播最佳密度,在现有施肥水平和管理条件下,以穴定植3株,定植密度6000株/667m2最佳.

| Abstract: | In order to explore appropriate planting density of rape, 2 rape seedlings, 3 rape seedlings, 4 rape seedlings and 5 rape seedlings per hill with spacing 33.33 cm in no tillage tobacco field were studied. The results showed that under the condition of current fertilization and management, 3 rape seedlings per hill, planting density of 6000 plants/667m2 could obtained the highest yield. |
