How to store carrots (how to store carrots without turning black)

1. The storage ditch of carrots is generally 1~ 1.5 meters wide. If it is too wide, it will increase the influence of temperature, reduce the thermal insulation effect of soil, and it is difficult to maintain a stable low temperature in the ditch. The depth of the ditch should be 0.6 ~ 0.8m deeper than the local frozen soil layer in winter, and the length depends on the storage capacity. In the process of storage, the thickness of covering soil is adjusted with the change of environmental temperature to reduce the temperature in the ditch. The water storage ditch should be located in a place with high terrain, low water level and strong water storage capacity, extending from east to west.

2. If you buy carrots with leaves, cut off the leaves immediately when you take them home, because the leaves will continue to grow and absorb nutrients from the roots. After cleaning carrots, be sure to dry them with kitchen paper towels, wrap them in a newspaper and put them in a fresh-keeping bag, which can be refrigerated. Because carrots are not resistant to moisture, they must stay away from moisture.

3. Carrots are harvested, pre-stored and piled in the pit. When stacking, first lay a layer of 10cm thick wet sand at the bottom of the cellar. It is advisable to knead the wet sand into a ball by hand without adding water. A layer of radish or carrot is added with a layer of sand to fill the gap, and the stacking height is generally not more than 2m. Put a straw as a vent every 1.5m~2m. Into the pit should pay attention to ventilation in the early stage and strengthen coverage in the later stage. The temperature in the cellar is controlled at 0℃ and the relative humidity is controlled at 95%. When the air is dry, you can spray water on the sand. This method can be preserved for 3~4 months.

4. Put radish or carrot in a plastic bag with a length of 50cmx 100cm for cellar storage, ventilation storage or mechanical storage. The storage of the plastic tent is to lay a layer of plastic film on the bottom of the pile and pile it into a rectangular pile with a width of 1m, a height of 1.5m and a length of 4m~5m, then fasten the plastic film tent, roll it tightly with the bottom film and tamp it with soil. Pay attention to leave an outlet on the account.

5. Carrots can be piled in the cellar or ventilated warehouse, or stacked, not too high. Generally, the pile height is 0.8~ 1 m, otherwise the temperature in the pile is high and perishable. In order to enhance the ventilation and heat dissipation effect, a ventilation pipe can be set every 1.5~2 meters in the reactor. Generally speaking, the heap will not be inverted during storage. Layering with wet sand in cellar or warehouse is better than bulk stacking, which is convenient for moisturizing and accumulating carbon dioxide. Pay attention to the temperature of the cellar or warehouse, and cover it with a straw curtain if necessary to prevent freezing. Regular spot checks are made during storage, and rotten products are found to be removed from the shelves in time.
