1.初期管理(入窖后20天) 入窖初期,害外温度高,地瓜呼吸作用强,易造成窖内高温高湿而引起烂窖。预防措施:入窖初白天打开门窗气眼通风降温。当夜间温度降到10℃时关闭门窗气眼,使窖温稳定在10～13℃,相对湿度控制在80～90%。采用高温愈合处理的,入害后关闭门窗气眼,升温到20℃相对湿度90%,经10天,再降温处理,温度降到14℃左右。 2.中期管理(入窖后20天至翌年立春) 由于窖外温度低,窖内温度高,窖内外温差大,地瓜发热少易受冻。预防措施:随气温下降逐渐关闭门窗气眼。当温度降到12～13℃时,并有继续下降趋势,在地瓜上盖20～26厘米干草。此期窖温以11～13℃为宜,相对温度90%左右。 1. Initial management (20 days into the pit) Into the cellar initial stage, high temperature damage outside, strong effect of sweet potatoes breathe, easy to cause high temperature and humidity inside the pit caused by bad cellar. Preventive measures: into the cellar to open the windows and doors at the beginning of daylight ventilation and cooling. When the temperature drops to 10 ℃ at night, close the doors and windows, so that the pit temperature stable at 10 ~ 13 ℃, relative humidity control at 80 ~ 90%. The use of high-temperature healing treatment, into the door and window closed after the eye damage, heating to 20 ℃ relative humidity of 90%, after 10 days, and then cooling treatment, the temperature dropped to about 14 ℃. 2. Medium-term management (20 days into the pit to the beginning of the following spring) Due to the low temperature outside the cellar, cellar temperature, cellar temperature difference between inside and outside the large, sweet potatoes less susceptible to heat. Preventive measures: Gradually close the doors and windows with the temperature drop. When the temperature dropped to 12 ~ 13 ℃, and continue to decline in sweet potatoes cover 20 to 26 cm hay. The pit temperature to 11 ~ 13 ℃ appropriate, the relative temperature of 90%.
