Embodiment 1

[0028] A sweet potato fresh-keeping method, the steps are as follows:

[0029] 1) Construction of fresh-keeping warehouse: the construction of the warehouse adopts brick concrete structure, and the storage capacity accounts for 70-80% of the total space. The wall is equipped with thermal insulation materials, and active ventilation equipment and temperature and humidity adjustment equipment are installed;

[0030] 2) Fresh-keeping warehouse treatment: use dried wormwood, houttuynia cordata, and dodder to smoke for 60 minutes. After the smoking is completed, spray high manganese with a concentration of 0.1mol / L on the inner wall, ground and top of the fresh-keeping warehouse. Potassium acid solution, after spraying, seal it for 12 hours, then ventilate for 3 days, and ventilate with the outside;

[0031] 3) Selection of sweet potatoes: choose normal sweet potatoes without insect eyes, damage and deterioration;

[0032] 4) Treatment of sweet potatoes: Wash the selected sweet po...

Abstract

The invention discloses a sweet potato fresh-keeping method. The method comprises the following steps: 1) fresh-keeping storehouse establishment; 2) fresh-keeping storehouse treatment; (3) selection of sweet potatoes; (4) treatment of the sweet potatoes; 5) placement of the sweet potatoes; and (6) daily management. Fumigation is performed with hay consisting of dried artemisia argyi herbs, herba houttuyniae, semen cuscutae in an equal ratio, and the artemisia argyi herbs and the herba houttuyniae have a synergistic effect, so that the disinfection and sterilization environment in the fresh-keeping storehouse can be further guaranteed, and fresh keeping of the sweet potatoes is facilitated; a fresh-keeping agent containing components including modified lignin and the like is added, so that the fresh-keeping effect is extremely good, and the fresh-keeping time of the sweet potatoes is further prolonged; through an active ventilation equipment in the application, a cyclone is formed, and meanwhile, the air spraying range is enlarged, so that the air circulation effect is better, thus faciliating fresh keeping of the sweet potatoes; by installing a storage frame, the sweet potatoes can move in the space of the fresh-keeping storehouse to fully adapt to the environment in the whole fresh-keeping storehouse, so that the situation that the fresh-keeping effect of the sweet potatoes in different positions is influenced due to difference in temperature and humidity of different positions in the fresh-keeping storehouse is avoided.
