Overwintering storage method of sweet potato seeds

Abstract

The invention relates to an overwintering storage method of sweet potato seeds, comprising the following steps: (1) preparation before storage: adopting a cellar storage method, and performing comprehensive disinfection on a cellar before the storage; (2) storage: selecting the sweet potato seeds of uniform sizes, immersing the selected sweet potato seeds in 1%-3% uniconazole, and taking out the sweet potato seeds to dry water content on surfaces of the sweet potato seeds; (3) during storage: closing and sealing the cellar firstly, and opening the cellar for ventilation; and (4) daily management: controlling temperature and humidity of the storage environment after putting the sweet potato seeds in the cellar. According to the overwintering storage method of the sweet potato seeds disclosed by the invention, a dry environment can be well kept to prevent sweet potatoes from being affected with damp and mildewing, carbendazol is used to kill harmful bacteria in the cellar so as to prevent the bacteria from injuring the sweet potatoes in storage; as the sweet potato seeds are immersed in the uniconazole, and advanced sprouting of the sweet potato seeds can be inhibited effectively. The overwintering storage method of the sweet potato seeds disclosed by the invention has the characteristics of simplicity in storage, reduced mildew and decomposition during the storage, high freshness and high sprouting rate of the sweet potato seeds.

Description

technical field [0001] The invention belongs to the technical field of agricultural product storage, and in particular relates to a method for overwintering storage of sweet potato seeds.

Problems solved by technology

[0003] Sweet potatoes have strict requirements on temperature and humidity during storage. Sweet potatoes are easy to freeze and form a hard core when placed in a place with too low temperature. When placed in a place with too high temperature, they will sprout again. cause fungus to rot

The existing storage method generally adopts the method of adding lime powder in the cellar for storage. However, after the lime powder absorbs water, it is easy to generate heat, which is easy to cause fluctuations in ambient temperature, which is not conducive to the storage of sweet potatoes, resulting in sweet potato seed mold during storage. change and rot
