Why do sweet potatoes rot so much in the ground?

In fact, there are several reasons for the rot of sweet potatoes, generally because the temperature in the sweet potato cellar is too low, resulting in too large a temperature difference to speed up the metabolism of sweet potatoes, to put it bluntly, it is the damage of cold air. The sweet potato cellar is too cold and there is too much cold air, which causes the sweet potato to be unable to stand this temperature, so the skin of the sweet potato will be frostbitten, which is similar to the meaning of human frostbite, which is injured because the weather is too cold. This has a big reason with the time we harvest the sweet potatoes, if we harvest too late, then we will delay the storage of the sweet potatoes, and we should properly advance the harvesting work, so as to avoid the rotting of the sweet potatoes, and we have the best storage time in time.

Sweet potatoes are rotten in the ground, maybe it's raining heavily, or there is some kind of disease. You can go to the agricultural technology department for advice. It may be that there has been heavy rain recently, or that there are pathogenic bacteria.

Because of the abundant rain and high moisture content of the soil, it is easy to rot the unharvested sweet potatoes that are still in the ground.

Because of the bumper harvest of sweet potatoes, there is no time to harvest.

And they all grow in the ground and can't be seen at all, so they will rot in the ground.

Because there is a lot of water in the ground and there are many microorganisms, sweet potatoes are easy to rot in the ground for a long time.

Because there is a lot of water, it is easy to rot if it is not collected in the ground for a long time.

Probably because of the moisture. Sweet potatoes prefer a drier environment and prefer sandy soil.

Why are you so rotten in the ground? I think that the fact that redstone is so much in the ground is that the moisture down there is too much, so I said that it is more prone to rot in geography.

I don't know which kind of sweet potato rot it is, and there are many reasons for sweet potato rot as follows; 1.Sweet potatoes began to rot after 10 days of frost damage. 2.

There are injuries; Such as digging wounds, puncture wounds. Crushes, bruises, insect injuries, germs are easy to infect, such as high temperature, high humidity and poor ventilation, and begin to rot after 7 days. 3.

Sweet potatoes are raining at the time of storage, and there is a lot of rain in the later stage of planting, and it may be that your sweet potatoes are not disease-resistant. Sweet potato storage has a lot to do with the variety. 4.

There are injuries and diseases, frostbite and decay quickly in the early stage. Non-resistant varieties with bacterial infection decay quickly in the later stage. Sweet potatoes should be stored at 11-14 degrees Celsius with a humidity of 90%.

Disease prevention 70% methyl and sweet potato preservatives are used.

The digging was late, and secondly, there was too much moisture in the ground.

A variety of factors, non-detoxified seedlings heavy planting, diseases and insects, flooding, planting methods, etc.

Sweet potatoes are bad in the field because there are pests and diseases, so how to control the pests and diseases in the sweet potato field?

1.When we choose a field area, it is best to implement the water and drought clock, that is, if we plant rice in the first half of the year, we will plant sweet potatoes in the second half of the year, and we will plant one water and one drought indirectly, which is more conducive to the prevention and control of pests.

2.In order to prevent insect infestation caused by insect eggs left in the field, 667 square meters were mixed with 100 kg of fine soil with 1 000 ml of 50% phoxanthion and evenly sprinkled into the plough bottom furrow when plowing.

3.There are two more important times for sweet potato pests and diseases, one is the growth and development period, at this time we need to focus on the pest control, we can spray Lesben, it is a very permeable insecticide, it will be conducted through the vines to the underground, the underground pests are killed, and the underground potato lumps are protected. Spray once every half a month or so, 1000 times the dilution solution.

Spray about four times in a row. Spray on the leaves.

4.There is also a very important time is the rapid expansion period, we can pour the tea bran aqueous solution from the root, dilute it about 40 times, and drench it once in about 8 days, and drench it two to three times in a row. Try to drench enough, and you can drench it into the roots.

5.One of them is a pest of small weevils, and about 40 small weevil traps are placed per acre. It can also be effective in controlling this pest.

6.If it is planted in a large area, you can also install a frequency-vibration insect trap lamp to trap and kill insects.

7.If conditions permit, start the seedling breeding stage to cultivate seedlings in groups to prevent seedling diseases and pests.

The temperature suitable for sweet potato storage is about 10 degrees, and the humidity is also required, and the sweet potatoes harvested in autumn in the north are generally stored in the cellar, with suitable temperature and humidity, and can be stored until next spring.

It should be that there is too much water in the ground and it is rotting.

Too much water, too much moisture.

It is usually bitten by bugs or rats.

This has a lot to do with the soil quality of growing sweet potatoes, generally if a piece of land is planted for three or four years, there will be bacteria that cause sweet potatoes to deteriorate, so if large-scale planting at least changes the raw land every year, or replant corn for a few years or something, and then continue that will be better.

One is to get sick, and the other is to rot if buried in the soil for a long time.
