How to grow sweet potatoes? These planting tips you need to know

There are many food crops in our country, such as corn, rice and sweet potatoes, and these all play a relatively important role in our lives. But compared with sweet potatoes, growing other food crops is more troublesome. This is because sweet potatoes have strong growth ability and adaptability, and do not need to be observed all the time every day, but growing sweet potatoes actually also requires certain skills. Today the editor brings you sweet potato planting tips, let's take a look!

1. Sprouting and seedling raising

Everyone surely knows this: to grow high-yielding, good-quality sweet potatoes is closely related to the seed potatoes. First, when selecting seed potatoes, choose ones of medium size with a smooth surface and no obvious wounds or pits. After selecting them, place them in the seedling raising holes, ensure the soil temperature and humidity, and provide a good environment for raising seedlings. Then cover the seed potatoes with a layer of soil and plastic film to improve the soil's water and fertilizer retention. Do a good job of sprouting and raising seedlings from the seed potatoes, ensure the robust growth of the sweet potato plants, and lay a solid foundation for the later yield.

2. Sowing time

Controlling the sowing time of sweet potatoes well can effectively increase the yield of sweet potatoes. When the growing environment fully meets the conditions, we can appropriately sow earlier. Sowing earlier can lengthen the growth period of sweet potatoes, which is conducive to their swelling, strengthens quality and increases weight. This makes the sweet potato yield greater, and thus can also improve the economic benefits of planting. But note that you can only sow within a suitable time or sow earlier, and must not plant too late. Sowing too late will affect the swelling and sugar content of sweet potatoes, reducing their commercial value and yield.

3. Checking and selecting seedlings

After sowing and emergence, be sure to promptly observe the emergence of sweet potato seedlings, as the selection of seedlings is very important. We should promptly pull out the seedlings that grow too weakly and are thin and small, and choose those thick, strong seedlings as the planting seedlings. This is because even if those weak seedlings survive after planting, their yield will be disastrous. They not only consume too many nutrients, but also compete with other healthy seedlings for nutrients, doing harm and no good. When planting, pay attention to the planting depth, about 5 cm, so as to ensure the growth of the seedlings and increase the yield.

4. Covering with plastic film

After planting the seedlings, cover them with plastic film in time. The main purpose is to strengthen the soil's water and fertilizer retention, prevent the loss of water and fertilizer, and avoid hindering seedling growth. Maintain the surface soil temperature to promote seedling growth. At the same time, it can also effectively prevent the invasion of pathogens, reduce the disease incidence, and improve the survival rate of the seedlings. After covering the plastic film well, water and fertilize in time according to the growth of the seedlings. Sweet potatoes have a relatively large demand for potassium, so when fertilizing, the proportion of potassium fertilizer can be appropriately increased to ensure the swelling of the roots and stems.

The above is a brief introduction to sweet potato planting tips. The environment for growing sweet potatoes is very simple. However, sweet potatoes grow relatively slowly, although they do not need growers, so it is necessary to make all preparations before planting. The early growth of sweet potatoes is very important, and I hope everyone can pay attention to it. That is all for today's introduction.
