How to Store Carrots in Winter? Detailed Guide to the Latest Methods

Carrots are a very nutritious vegetable and are grown on a very large area in China. When growing carrots, management work is certainly important, but storage after harvest cannot be ignored either. Especially in low-temperature winter conditions, if storage work is not done well, it will have a great impact on economic returns. So how should carrots be stored in winter? Let's take a look together with the editor below!

1. Trench storage

When storing carrots in trenches, first dig the storage trench well. The width of the storage trench should be kept at about 1 m. It must not be too wide; if it is too wide, it will affect the temperature, reduce the soil's insulation effect, and fail to effectively maintain the temperature inside the trench. The depth should be about 70 cm deeper than the local winter frozen soil layer. Then control the length of the trench according to the storage volume. During storage, adjust the thickness of the covering soil appropriately according to changes in the environment. The storage trench should be chosen in a place with high terrain, a low water table, and strong soil water retention to ensure the storage effect.

The carrots can be spread directly in the trench, with a thickness kept at about 50 cm. To prevent the carrots at the bottom from rotting due to excessive heat, they can be layered and stacked with wet sand, which can improve humidity retention and increase the carbon dioxide content around the carrots. Before putting them into the trench, cover the surface of the carrots with a layer of fine soil, then cover with soil in batches as the temperature drops, mainly to avoid rotting or freeze damage. Then pay attention to observing the temperature inside the trench so it can be adjusted in time.

2. Stack storage

Carrots can be stored in a cellar or ventilated warehouse in loose piles or stacked in stacks. The stacking height should not be too high, generally kept at about 1 m; if it is too high, it can easily cause carrots to rot. To improve the ventilation and heat dissipation of stack storage, a ventilation tube should be set up about every 2 m between stacks. When storing in stacks, it is best to layer them with wet sandy soil, which works much better than loose piling. It can improve moisture retention and carbon dioxide. At the same time, pay attention to the temperature in the cellar. When it is too low, cover appropriately with straw curtains to avoid freezing. Finally, check regularly, and if any rotting is found, pick those carrots out in time.

3. Semi-closed storage method

The semi-closed storage method is also mainly carried out in a ventilated warehouse. First, stack the carrots in the ventilated warehouse into several rectangular stacks. At the beginning of storage or before the warehouse temperature rises, cover the stacks with plastic film. The bottom of the stacks does not need to be lined with film, maintaining a semi-closed state, which can reduce oxygen concentration and prevent carrots from oxidizing. Maintain a high-humidity environment to improve the storage effect of carrots. During storage, the film can be uncovered regularly for ventilation and air exchange to maintain a good environment.
