摘　　要：百合种球冷藏及冷藏中的技术管理过程,是百合种球采后处理至关重要的环节,加快其应用研究,对推进百合种球国产化有着积极而深远的意义。为此,针对目前国内在百合种球冷藏中,无合适的仪器设备对冷藏中的百合种球产生的CO2气体进行监测调控的情况,提出在种球冷藏库中,利用CO2检测模块及控制电路对库内CO2气体进行24 h监测,当检测到超过库内冷藏种球承受的CO2浓度值时(如1 500×10-6),通过一系列控制电路,自动实施对CO2气体进行抽排,直到趋于正常。解决了因不能及时监测到CO2气体浓度超标,导致冷藏种球(植物)受到危害的问题。Lily bulb cold store and the process of cold store technology management are the key link in the postharvest. Therefore, it is meaningful to strengthen the research for localization of Lily bulb production. This study suggested that CO2 detection module and control circuit was used to monitor the CO2 in cold store 24 hours, because now there is no appropriate equipment for monitoring the CO2 regulation situation. This study found the way that pumped the CO2 gas automatically until the concentration reaching to the normal level by the control circuit, when the equipment detected the CO2 gas concentration in the cold store exceeding the level which bulbs can endure （ eg. 1 500 ×10^-6）. This study also solved the problem that the bulb/plant in the cold store would be harmed because of the incapability of monitoring excessive concentration of the CO2 gas.
