| 中文摘要: |
| 通过对秋甘蓝“京丰一号”逐株记载蚜量、植株长势及经济产量系统调查,明确秋甘蓝移栽后的幼苗期不能遭受蚜害;生长良好的一类苗,莲座期可耐蚜量主峰日3000头/株以下;但结球始期蚜量与产量有显著关系,不应受蚜害。 |
| 英文摘要: |
| Aphid density, growing power of the plant and economic yield of the crop were recorded by systematic investigation on the Autume cabbage “Jingfen-1”. The results showed that the cabbage plants grown well were able to tolerate the injury of less than 3 000 aphides per plant, especially 1 500 aphides per plant at the precupping stage. However, at the cupping stage, there was significant relationship between the aphid density and the yield of the common cabbage; therefore, the cabbage plants must be free from the infastation by aphid in that time. |
