How to preserve spinach for a long time in the latest winter

Spinach is a popular vegetable, with autumn spinach, spring spinach and so on. But now through out-of-season cultivation, it can basically be planted all year round. When growing spinach in winter, if it is not all on the market after harvest. Then we need to do a good job in the long-term preservation of spinach to avoid freezing damage to spinach. So how to preserve spinach for a long time in winter? Let's take a look at it with the editor.

1. The method of combined border and frozen storage

The first step of frozen storage is to select the soil where spinach grows healthily and the combinations frozen with it. Each combination is about three rows. First of all, all the roots of spinach that need to be frozen should be eradicated, and the depth should be kept at about 1.5cm. When uprooting the roots, pay attention to keeping the vegetables neat. Then cover the left and right of the three beds of spinach on the frozen border in the middle. The leaves go down and the roots go up, and three rows of spinach are combined into one bed. On the day of storage, the soil should be used to bury it strictly and gently pat it tightly to ensure that it is closed between the top and bottom to avoid the invasion of thieves.

2. Ground frozen storage

A week before the spinach harvest, first level the frozen ground, and then splash water to ensure that the surface of the soil does not thaw. During storage, you should sprinkle some vegetable leaves on the ground as the ground. Then tie the spinach together, each bundle next to each other on top. Then cover the spinach with vegetable leaves, straw and so on about 10 cm thick. When the inside of spinach freezes, cover it with a layer of sand about 10 centimeters thick to prevent spinach leaves from losing water and reduce commodity value.

3. Unventilated storage

Where there is shade, dig a ditch in balance with it, and the width of the ditch is about 30cm. The depth should be similar to the height of spinach, not too deep, and the distance between each ditch should be greater than 20cm. Bundle up the spinach that needs to be stored and put it upright in the ditch with the root down. Then sprinkle dry soil on the spinach and just cover the spinach. Then, with the continuous decrease of temperature, the work of covering soil in batches should be carried out. Cover the soil to ensure that there are no cracks, play the role of windproof and moisturizing. Finally, it is best to keep the temperature around minus five degrees Celsius to keep the spinach in a slightly frozen state.

4. Ordinary frozen storage

Ordinary frozen storage means that the spinach that needs to be refrigerated is frozen on the ground at night and can be thawed and harvested at noon. When harvesting, keep the root length around 1.6cm, clean up the soil, and then arrange the bundles. Put it in a cool place to dry the dew and lower the temperature of the vegetable. Wait until the weather is getting cold and frozen, the storage place should have a better degree of shade. Flatten the ground, and then dig a suitable storage ditch to keep the distance between the ditches at about 12 cm. The root is lowered into the ditch, the thickness is controlled at about 25cm, and then the grass is covered in the deep winter, and the temperature in the ditch is controlled between minus seven degrees and minus six degrees.

The above is a brief introduction to how spinach is preserved for a long time in winter. That's all for today's introduction. This article is for reference only. I hope it can help you all.
