Light: Scattered light can be used to illuminate seed potatoes in the later stages of storage. The minimum scattered light intensity is 75Lux.

Temperature: 4℃-6℃

Relative humidity: 85% - 95%

Gas composition: CO2 concentration should not be higher than 0.5%

Lighting: Fresh potatoes should be stored away from light, and low-power electric lamps should be used during lighting operations.

Temperature: 6℃-10℃

Relative humidity: 85% - 95%

Gas composition: CO2 concentration should not be higher than 0.5%

Processed potatoes should be stored away from light, and low-power electric lamps should be used for lighting operations.

The temperature of the high-temperature warehouse is relatively stable and is mostly used for seed potato storage.

Harvesting should be done before frost, on a sunny day and when the soil is dry.

Harvest when the potato plants are withered and the underground tubers have entered the dormant period.

Cut off the plants, plow the potatoes deeply and dry them in the field for a while, but do not expose them to the hot sun.

Grading processing can improve the economic benefits of potatoes, facilitate classification, storage and transportation, and can also reduce the spread of diseases.

Indoors, under a shade, or in the open air at a temperature of 13℃-18℃ and a relative humidity of 85%-95%

The height should not exceed 0.5 meters, the width should not exceed 2 meters, and ventilation ducts should be installed in the pile.

There should be no more than 6 layers, the width of the stack should not exceed 2 meters, the distance between stacks should not be less than 0.6 meters, and the direction of the stack should be consistent with the wind direction.
