Many people know that sweet potatoes have a warm climate and are not cold-resistant. Usually in spring and summer, it is the sweet potato season in autumn, and playing sweet potatoes can only wait until tomorrow's spring; In fact, the climate in different places is different, even in winter, some places are not very cold, but also sweet potatoes; After the autumn harvest, the land is idle. Some people choose a sweet potato, just like a hometown, the south. Some people can say that it is four seasons red potato. When harvesting sweet potatoes in autumn, what kind of attention should be paid to sweet potato vines and how to manage them to be safe and not freeze in winter, which is better? The following points:

First, understand some requirements of sweet potato growth.

1, the temperature should be appropriate.

The growth of sweet potato needs suitable temperature. The temperature is over 20 degrees, and 30 degrees is suitable. When the temperature is lower than 16 degrees, the temperature will increase slowly or even stop. If it is lower than this temperature in a short time, the impact is very small. If it continues to be low, the freezing damage will be lower than 10 degrees, which has a great impact. Sweet potato vines will be frozen and cannot grow.

2. Sufficient light

The growth conditions of sweet potatoes are not required. In addition to the temperature requirements, other aspects are also needed. The sweet potato is not very good. The sweet potato should be as small as possible, and the sweet potato should have enough light. Otherwise, there are not enough vines, ponies and pots, and the sweet potato on the ground is not good enough.

3. Strong adaptability and low requirements for soil.

Sweet potato has strong adaptability to soil environment, and can grow in acid and alkali, drought and general land. However, considering that the growth of sweet potato, the absorption of fertilizer water, the expansion of underground cake and sweet potato are related to the yield, deep soil should be selected. Pine, water-water, water supply and strong land are relatively strong, so besides cutting and planting, water is also necessary. If it is not particularly dry, the natural rainfall from time to time is not intentional.

4. The demand for chemical fertilizers has increased.

Everyone has seen sweet potatoes, and vines begin with vines. There are many sweet potatoes on the ground. Sweet potatoes should be so strong. So many sweet potatoes need more fertilizer. Fertilizers are only nitrogen, phosphorus and potassium fertilizer. Nitrogen fertilizer mainly affects the growth of stems and leaves, while phosphorus and potassium mainly affect the content of sweet barn and heading size.

Second, several necessary operations after sweet potato harvest in autumn.

1, strengthen the land first.

Because it is a sweet potato after the autumn harvest, and the crops have matured for a long time, no insects are sprayed, plus there are many dead leaves, pests, and the weather is not cold, some pests are still active, so the land can be sterilized and disinfected to eliminate some pests and insects.

Step 2 choose cutting and planting

Harvest in autumn, then go in winter. The weather fainted. It needs sweet potatoes to grow. It takes time. Not appropriate. It should directly enter the existing sweet potato vine and cut it into a stable plant; Note that the sweet potato vines to be cut should be thick vines without pests.

3. Ridge planting

Sweet potatoes are generally removed. Sweet potato vines grow in autumn and winter, so remove ridges, cool, cool, unload and keep water. Sweet potato vines are better and smooth in winter. Especially the soil, the soil quality is poor and the water saving is poor.

4. Water in time after cutting.

The land harvested in autumn is relatively dry, and autumn itself is relatively small. Sweet potato vines should be watered and planted in time to reduce sweet potato vines, which is stable and fast.

Third, the management of sweet potato safety.

1, the soil behind the soil

After the sweet potato is cut, it usually takes 7 days to take root. If you can touch it for half a month, the apex of your heart will bring rusty people to the animals. Urea is urea, which was found in fertilizer and then buried. If it rains, it is necessary; If it doesn't need water, the challenge is this. If you need water, you can wait a few days after watering, and the weather will be better. The second fertilization will be carried out when the weather is better. Tampula

2, no vines, potato leaves

Although some places can make sweet potatoes in winter, fertilization is enough, but the growth is not as good as that in summer, and the vines are not normal, but the vines are not long and the summer is not so full; You don't have to choose vines, so there are few green leafy vegetables in winter, but it is not recommended to choose sweet potato leaves, which will affect the growth of sweet potatoes and their knots.

Step 3 equip

In winter, the light is relatively small, and the sweet potato grows brighter. When the sweet potato is relatively dense, the sweet potato vine is relatively uniform, which promotes growth. In addition to sun exposure, aging, sterilization and disinfection, raising the land temperature is conducive to the smooth winter of sweet potatoes.

4. Plastic film and sweet potato vine can be considered.

In winter, it can grow sweet potatoes. Although the overall temperature is warm, sometimes the weather changes suddenly. Suddenly people feel obviously cold for a few days. They can't stand it without cold sweet potatoes. They may stop growing temporarily, or they can be planted normally, but the weather will gradually clear up. Therefore, it is necessary to consider using plastic film in the arcade cover and restore the temperature to normal temperature. Movies can be sunny. It is possible for people to have a sweet potato after autumn because of the warm climate in winter, but we must pay attention to the opening of soil, water and water to make the sweet potato vine safe. Management includes chasing soil, turning around, etc.
