In addition, make sure there are no dry, brown new roots growing out from the bottom. Check to see if the shoot at the top of the bulb is more than 3cm in length; this indicates that the bulb's storage environment was not good or was too damp, which makes it likely that the bulb is unhealthy.
此外，再檢查根部是否發過乾褐的新根，芽頭是否超過三公分，這都代表儲存環境不良或受潮，容易造成病球。
