君子兰叶片基部合生,形成了沟通地上部分与地下部分的重要组织——假鳞茎。其上部抽生叶片,下部萌发新根。理论上讲,叶片生长与根系萌发之间存在一种动态平衡:新叶越多,假鳞茎越大,新根萌发空间越多;新根越多,植株营养越充分,新叶抽生也越快。然而实际情况是,君子兰老叶自然枯黄比较缓慢,尽管抽生新叶使假鳞 Clivia leaves at the base of symbiosis, forming an important part of the communication between the ground and underground parts - pseudobulb. The upper pumping leaves, the lower germination of new roots. In theory, there is a dynamic balance between leaf growth and root germination: the more new leaves, the larger the pseudobulb, the more germinated space for new roots; the more new roots, the more nutrition the plants, fast. However, the actual situation is that the old leaves of Clivia are naturally yellowish, although the new leaves make the false scales
