甘薯贮藏的环境要求较高的湿度,严格的温度。整个贮藏期间窖温应控制在10～15℃,最适合的温度在12～13℃之间;高于15℃易生芽,低于10℃易受冷害引起腐烂。湿度过低易使薯块干缩糠心,湿度过高则易导致病菌的繁殖蔓延而引起病变腐烂。甘薯贮藏的最适宜湿度为90%～95%。当窖内相对湿度低于80%时,引起甘薯失水萎蔫,食用品质下降;相对湿度大于95%时,呼吸虽然降低,但微生物活动旺盛,易受病害。具体管理工作一般分三个时期。一、前期管理。入窖初期以降温散热为主。刚收获的鲜薯入窖20天内呼
Sweet potato storage environment requires higher humidity, strict temperature. The cellar temperature should be controlled at 10 ~ 15 ℃ throughout the storage period, the most suitable temperature is between 12 ~ 13 ℃; higher than 15 ℃ prone buds, less than 10 ℃ susceptible to chilling injury. Humidity is too low to make tubers dry shrink heart, humidity is easily lead to the spread of germs caused by pathological decay. Sweet potato storage of the most appropriate humidity of 90% to 95%. When the relative humidity in the cellar is less than 80%, the wilts lose water and wilting, and the eating quality declines. When the relative humidity is more than 95%, the respiration is reduced, but the microorganisms are vigorous and susceptible to disease. Specific management generally divided into three periods. First, pre-management. Into the cellar to cool the main heat. Just harvest the fresh cellar into the pit call within 20 days
