甘薯安全贮藏是甘薯生产的突出问题,必须掌握贮藏技术,才能达到安全贮藏的目的。(一)适期收获。甘薯块根为营养器官,无明显成熟期,地上茎叶也没有显著的成熟标志。因此,收获适期应主要根据当地的气候条件,耕作制度及薯块用途决定。当气温降至15℃时,茎叶生长和薯块膨大停止,即可开始收获。如过早,产量和晒干率低。温度较高时收获,入窖前期高温高湿持续时间 Safe storage of sweet potato is a prominent issue in the production of sweet potato, must master the storage technology, in order to achieve the purpose of safe storage. (A) the right harvest. Sweet potato tubers as vegetative organs, no obvious maturity, ground stems and leaves did not significantly mature sign. Therefore, the harvest period should be mainly based on local climatic conditions, farming systems and tuberous purposes. When the temperature dropped to 15 ℃, the growth of stems and leaves and tubers expand to stop, you can start harvesting. Such as premature, low yield and drying rate. Harvesting at higher temperatures, into the cellar pre-high temperature and humidity duration
