The latest harvesting and storage methods of sweet potato

Sweet potatoes planted in spring can be harvested soon, and sweet potatoes need to be dug out of the ground, so we need to pay attention to some problems. After harvest, if the quantity is small, animal feed can be stored in a dry place for a short time, but if you want to keep the seed, you need to store it for the winter. Let's take a look at how it should be stored.

1. Harvesting method

When digging sweet potatoes, do not cause wounds or dig wounds. Or the thin root at the end of the end is broken, it will not work, sweet potatoes will immediately flow out of juice, easy to rot. Not resistant to storage. Dug sweet potatoes can not be washed and stored, it is easy to go bad. It should be placed in a dry and ventilated place for a short time. When harvesting and transporting, handle it gently and don't bump against the wound. Full-ripe sweet potatoes do not stay in the ground all the time, they are easy to rot.

2. Selection and processing

Store large and good sweet potato seeds to make seed potatoes, and take out those that are broken, cut, bruised, moth, and already rotten. Then spray a certain concentration of carbendazim solution to sterilize, or soak sweet potatoes in 1000 times carbendazim solution, soak one by one, take it out to dry and then store it. There is no bacteria in this way and it is not easy to rot.

3. Cellar storage

A cellar was built in the south to store sweet potatoes, and the cellar dug in a cool, dry place was half underground, entering and leaving directly through the hole in the ground. Open the hole, put it in for a few days and then clean it up to avoid lack of oxygen. After cleaning, spray carbendazim, then put the sweet potatoes in, lay them flat, do not overlap.

4. Points for attention

Generally, you can go down and check for a period of time. The whole underground cellar is prone to lack of oxygen. Take a good candle to test before going down. When the fire goes out, there is no oxygen. We can't go down rashly. There is also a cave storeroom. But it needs to be dug in a place with a lot of sand. And higher ground. There is usually no lack of oxygen. But small animals are easy to enter and need to be paid attention to.

When picking sweet potatoes, pay attention to digging, let the sweet potatoes appear and take them out directly, do not cause wounds. After storage treatment, it is more resistant to storage, and pay attention to safety in the use of the cellar.
