Embodiment 1

[0015] A method for overwintering storage of sweet potato seeds, comprising the following steps:

[0016] (1) Preparation before storage: adopt the cellar storage method, thoroughly disinfect the cellar before storage, and spray 50% carbendazim wettable powder diluted 800 times with water in the cellar;

[0017] (2) Storage: Choose sweet potato seeds of uniform size, soak them with 2% uniconazole for 20-25 minutes, and take out the surface water for drying; after the surface water of sweet potato seeds is dry, put them in the cellar for storage. It is necessary to lay a layer of pine needles on the bottom of the cellar, and then overlap the sweet potato seeds in a layer of pine needles and a layer of sweet potatoes. The overlapping height of each layer does not exceed 80 cm, and the thickness of each layer of pine needles is 2-3 cm. And the top layer of sweet potato should be covered with straw with a thickness of 15-20cm for heat preservation, and the temperature in the sweet...

[0021] A method for overwintering storage of sweet potato seeds, comprising the following steps:

[0022] (1) Preparation before storage: adopt the cellar storage method, thoroughly disinfect the cellar before storage, and spray 50% carbendazim wettable powder diluted 1000 times with water in the cellar;

[0023] (2) Storage: Choose sweet potato seeds of uniform size, soak them with 3% uniconazole for 15 to 20 minutes, and take out the surface moisture for drying; after the surface moisture of the sweet potato seeds is dried, put them in the cellar for storage. It is necessary to lay a layer of pine needles on the bottom of the cellar, and then overlap the sweet potato seeds in a layer of pine needles and a layer of sweet potatoes. The overlapping height of each layer does not exceed 80 cm, and the thickness of each layer of pine needles is 2-3 cm.

Embodiment 3

[0027] A method for overwintering storage of sweet potato seeds, comprising the following steps:

[0028] (1) Preparation before storage: adopt the cellar storage method, thoroughly disinfect the cellar before storage, and spray 50% carbendazim wettable powder diluted 1200 times with water in the cellar;

[0029] (2) Storage: Choose sweet potato seeds of uniform size, soak them with 3% uniconazole for 18-23 minutes, and take out the surface water to dry; after the surface water of sweet potato seeds is dry, put them in the cellar for storage. It is necessary to lay a layer of pine needles on the bottom of the cellar, and then overlap the sweet potato seeds in a layer of pine needles and a layer of sweet potatoes. The overlapping height of each layer does not exceed 80 cm, and the thickness of each layer of pine needles is 2-3 cm. And the top layer of sweet potato should be covered with straw with a thickness of 15-20cm for heat preservation, and the temperature in the sweet po...

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. Background technique [0002] Sweet potato, also known as sweet potato and sweet potato, is the tuberous root of an annual plant of the convolvulus family. The calorie content of sweet potatoes is very low, much lower than ordinary rice, so eating sweet potatoes does not have to worry about gaining weight.
