Sweet potatoes need to go into the cellar. What do you need to do before you put them in the cellar?

Sweet potato is the main food crop in China, and most of it has been harvested now. Sweet potato harvest needs to dig sweet potatoes out of the ground, and some problems need to be paid attention to. After harvest, if the output is too high to sell out, it needs to be stored in the cellar. Or if you want to preserve seeds, you need to store them in winter.

However, many people will find that sweet potatoes often dry up and rot when stored, which seriously affects the planting efficiency. So how can we store sweet potatoes to prevent rot? Today, the village small agricultural network will introduce the scientific harvesting and cellar storage skills of sweet potatoes in detail. Let's take a look!

1, harvesting method

When digging sweet potatoes, you can't cause wounds, and you can't dig wounds. Or the thin root at the end is broken. Sweet potatoes will immediately flow juice and rot easily. Not resistant to storage. The dug sweet potato can't be stored after cleaning, and it is easy to deteriorate. Put it in a dry and ventilated place for a short time. When harvesting and transporting, handle with care, and don't hurt the wound. Don't leave the fully ripe sweet potato in the ground all the time, it will rot easily.

2. Selection and processing

Store big and good sweet potato seeds as seed potatoes, and take out broken skins, gouges, bumps, moths and some rotten ones. Then spray a certain concentration of carbendazim solution for sterilization, or soak sweet potatoes in 1000 times of carbendazim solution, soak them one by one, take them out and dry them = store them again. This will not carry bacteria and will not rot easily.

3, cellar storage

In the south, cellars are used to store sweet potatoes. The cellars dug in cool and dry places are all underground, and they go in and out directly from the hole on the ground. Open a hole, put it in for a few days before cleaning, and go down to avoid hypoxia.

Before storage, we should first select the stored sweet potatoes to remove frostbite, wounds, pests and diseases, and green potatoes. And it should be put into the cellar in time after harvest, but the sweet potatoes that need to be put into the cellar should be dried for about 3 hours to reduce the moisture of sweet potatoes and avoid the rot of sweet potatoes caused by excessive humidity. After cleaning, put the sweet potatoes in and lay them flat, without overlapping. Village small agricultural network, make the profession of farmers fashionable!

After all pits are put into pits, the management of pits should be strengthened, and ventilation, water drainage and humidity reduction should be done well in the early stage of storage. It is the best storage temperature of sweet potato to control the temperature at about 65438 02 degrees. The humidity of the cellar should also be kept at about 80%, neither too high nor too low. If it is too high, it will cause pests and diseases, leading to sweet potato rot.

If it is too low, the water in the sweet potato is insufficient, which leads to the dryness of the sweet potato and reduces the commodity value. If the humidity in the cellar is insufficient, you can pour a small amount of water, and then pay attention to heat preservation and cold protection in the middle and late stages to prevent the invasion of ice and snow.

4. Preventive measures

You can usually go down and check for a while. Underground cellars are prone to lack of oxygen. You should take some good candles to test before you go down. If the fire goes out, there will be no oxygen. We can't rush down. There is also a cave storage room. But it needs to be dug in sandy places. And highlands. Generally, there is no lack of oxygen. But small animals are easy to enter and need attention.

When digging sweet potatoes, pay attention to digging, let the sweet potatoes appear and take them out directly, so as not to cause wounds. It is more resistant to storage after storage, and the wine cellar should be used safely.
