Abstract
The present invention relates to a multidimensional ecological preservation technology for sweet potatoes, including the following steps: collecting mature tuberous roots in proper time; and performing BTH soak cleaning to promote callus, and performing callus treatment as follows: pretreatment before storage, disinfection in a cellar, sand storage, tent air conditioning, and performing secondary cobalt ray irradiation at an irradiation dose of 0.1-0.5 kGy before the end of storage and marketing, thereby achieving dual guarantee of storage period and shelf life. In the present invention, the traditional sand is replaced with a sandy material (having a particle size of 1-3 mm), and the sandy material is lightweight, breathable, and high in water absorbing and retaining property, thermal insulation and heat preservation.
