以京丰一号甘蓝为试材，进行不同生育期不同去叶量试验。结果表明，同一去叶水平，不同生育期的株重变化不大，但株重以结球始期最低。在莲座期和结球始期去叶量为1／8时，其株重比不去叶略有增加，说明植株在这两个生育期对叶损失具有超补偿能力。
Taking Jingfeng No. 1 cabbage as test material, different leaf removal tests were conducted at different growth stages. The results showed that the same leaf removal level, different growth stages of the weight of little change, but the lowest weight of the beginning of the ball. In the rosette period and the beginning of the knot to leave the amount of 1/8, the weight of the leaves than the leaves did not increase slightly, indicating that plants in these two growth stages of leaf loss with super-compensatory ability.
