A new trick to prevent sweet potato from rotten cellar

Sweet potato is one of the main food crops in China, and now most of the sweet potatoes have been harvested. For some high-yield growers, it is impossible to sell them all, so they need to be stored in the cellar during harvest. However, many people will find that sweet potatoes often rot when storing sweet potatoes, which seriously affects the efficiency of planting. So how can we store it to prevent sweet potatoes from spoiling the cellar? Let's introduce it to you by the editor.

1. Carefully selected

Before storage, first of all, select the stored sweet potatoes and remove frostbite, wounds, diseases and insect pests and green potatoes. And enter the cellar in time after harvest, but dry the sweet potatoes that need to go into the cellar for about 3 hours to reduce the moisture of sweet potatoes and avoid excessive humidity leading to sweet potato rot. Try to avoid overnight storage, and it is best to store sweet potatoes after medicament treatment. First of all, soak the sweet potato in the new high-fat film for about 8 minutes, and then remove the air-dried potion, which can effectively prevent the threat of diseases and insect pests and reduce the phenomenon of sweet potato storage rot.

2. Disinfection in time

Disinfect the cellar a few days before harvesting sweet potatoes to prevent bacteria in the cellar from infecting the harvested sweet potatoes. First of all, we should first comprehensively clean the cellar, clean up the sundries and rubbish in the cellar, and try to avoid cleaning the cellar with water. Because of the low temperature and no light in the cellar, it is very difficult to dry after being wet. If the humidity is too high, it can easily lead to sweet potato rot. When cleaning the cellar, sprinkle the cellar evenly with quicklime powder to disinfect the cellar to eliminate the bacteria in the cellar and control the incidence of disease.

3. Reasonable stacking

Observe the size of the cellar during storage, do not pile it blindly, and do not fill the cellar too full. After storage, it is necessary to keep the space of cellar 1pm 3 or so, so as to avoid excessive stacking leading to difficulty in cellar ventilation and affecting ventilation. Otherwise, it will lead to a sharp rise in the temperature of the cellar, unable to change oxygen in time, resulting in a shortage of oxygen in the cellar. If there is not enough oxygen, sweet potatoes will produce a lot of alcohol, which will seriously affect the storage of sweet potatoes. Cause alcoholism of sweet potato, cause diseases and insect pests, cause rot.

4. Strengthen the management

After all entering the cellar, it is necessary to strengthen the management of the cellar and do a good job of ventilation and cooling, drainage and humidity reduction in the early stage of storage. Controlling the temperature at about 12 degrees is the best storage temperature for sweet potatoes. Cellar humidity should also be kept at about 80%, not too high or too low, too high will cause diseases and insect pests, resulting in sweet potato rot. If the sweet potato is too low, there is not enough water in the sweet potato, which will lead to the dryness of the sweet potato and reduce the commodity value. If the humidity in the cellar is insufficient, a small amount of water can be splashed, and then in the middle and later stages, we should pay attention to do a good job of heat preservation and cold protection to prevent the invasion of wind and snow.

The above is a brief introduction to the tricks of preventing sweet potato from rotten cellar, which is a common problem for many friends during storage.
