防治方法：空气湿度小于70%，贮藏时保持空气流通。
冠腐
染病的植株一般来说早期发育正常，随后，会出现枯萎、倒伏。病害很快传播到相邻植株上。发病原因：冠腐病由整齐小核菌引致。这种病只发生在亚热带和气候温暖的地区。低于13℃时，此病不侵染植株，当温度高于20℃时发病最厉害。

防治方法：避免阳光灼伤。球根种植不要过密，在生长期内保持土壤无杂草。温室中相对湿度保持80%左右，如必要，可打开风机并加热，保持植株干燥。上午浇水以保证植株干燥。叶面受损后，根据需要喷洒杀菌剂。

防治方法：对已被侵染或可能已被侵染的土壤中进行常规土壤处理。高温下，土壤再侵染仍有可能发生。保持清洁环境，可防再侵染发生。未采用常规土壤处理，据以往经验，土壤会被丝核菌侵染。一般用旋耕机在土下5~10cm处施用杀菌剂。通常在夏天土温超过16℃时采用此法。

防治方法：去除土壤中的植物残体。在已提前处理好的土壤中种植种球（温度适宜）。种植时避免碰伤根尖。温室内种植时温度保持在适宜的范围内（12~15℃），避免高温。清晨适量浇水。 防治土壤熟化。
