Carrots are also a common dish on the table. Because it has certain nutritional value, especially rich in β-carotene, regular consumption can alleviate some eye symptoms. Here are some ways to store carrots.

Goucang

Choose a place with high terrain, low groundwater level, heavy soil and strong water retention. The pipe trench is excavated in the east-west direction, and the trench width1~1.5m. If it is too wide, it will increase the influence of temperature and reduce the thermal insulation effect of soil, and it is difficult to maintain a stable low temperature in the trench. In winter, the depth of ditches is deeper than the local frozen soil layer, such as Beijing 1m deep soil layer.

Bamboo basket sand storage method

Spread a thick layer of kraft paper, a layer of fine sand, a layer of carrots and a layer of fine sand on the bottom of the bamboo basket, then put carrots at the basket mouth 8- 10 cm away from the basket, and seal the basket tightly with thick sand. The humidity of fine sand should be kept at 75%-85%. Then put the bamboo basket in the corner of the room for storage.

Mine storage and ventilation storage

Pit storage and ventilation storage of root vegetables are common methods in the north. It can be used for cellar storage and stacking. Radish pile height 1.2~ 1.5m, carrot pile height 0.8-1m. The pile body should not be too high, otherwise, a ventilation tower can be installed at the center of the pile body every1.5m. When it is first stored, it is generally not put upside down. After the spring, we can conduct a comprehensive inspection and dumping according to the storage conditions to remove the rotten root vegetables. During storage, pay attention to adjust the temperature of the cellar. When the temperature in the cellar is too high in the early stage, air holes can be opened to dissipate heat; Keep the cellar cold. In the cellar, it is best to use wet sand and product layering to keep moisture and accumulate CO2. In addition, moisture retention and heat preservation are two main problems of root vegetables in ventilated storage. In order to do a good job in the ventilation warehouse, it is best for the warehouse to adopt a layered way, and the inspection and stacking management are the same as those of the warehouse.

Film tent sealed storage

In recent years, Shenyang and other places have adopted the principle of controlled atmosphere storage, and stored root vegetables in warehouses with semi-closed membranes to inhibit water loss and germination, with good results.
