红薯的薯块为块根,皮薄,含水量高,不耐贮藏,管理不当常常造成烂窖。烂窖的原因可分为以下两种。一、生理性病害主要是由于温度不适造成。薯块生活所要求的最低温度约10℃左右,最高温度为20℃。如窖温长期低于10℃,则易发生冷害,使薯块生活力显著降低,从而诱发弱寄生菌的浸染,引起烂窖。
Sweet potatoes tuberous roots, thin skin, high water content, intolerance storage, improper management often cause bad cellar. The reason for the bad cellar can be divided into the following two kinds. First, physiological diseases are mainly caused by temperature discomfort. The minimum temperature required for tuberous life is about 10 ℃, the maximum temperature is 20 ℃. If the cellar temperature is lower than 10 ℃ for a long time, it is easy to produce chilling damage, which will significantly reduce the viability of potato tubers, thus inducing the dissemination of weak parasites and causing the rotting cellar.
