How to Grow Sweet Potatoes: A Detailed Guide to the Latest Planting Techniques
China has a great many food crops, such as corn, rice and sweet potatoes, and these all play a relatively important role in our lives. But compared with sweet potatoes, other food crops are more troublesome to plant. Because the sweet potato's growth capacity and adaptability are strong, it does not need to be watched all the time every day, but growing sweet potatoes actually also requires certain techniques. Today the editor brings you the planting techniques for sweet potatoes, let's take a look!
1. Sprouting and raising seedlings
Everyone surely knows this: if you want to grow sweet potatoes with high yield and good quality, it is closely tied to the seed. First, when choosing seed sweet potatoes, choose ones of medium size with a smooth surface and no obvious wounds or pitted areas. After choosing them, place them in the seedling holes, ensure the soil temperature and humidity, and provide a good environment for raising seedlings. Then cover the seed sweet 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 sweet potatoes, ensure the healthy 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 sweet potato's growth period, which is good for the swelling of the sweet potatoes, enhances quality and increases weight. It 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; you must not plant too late. Sowing too late will affect the swelling and sugar content of the sweet potatoes, reducing their commercial value and yield.
3. Checking and selecting seedlings
After sowing and emergence, be sure to observe the emergence of the sweet potato seedlings in time; the selection of seedlings is very important. We should promptly pull out the weak, thin seedlings and choose those thick, strong seedlings as the planting seedlings. Because even if those weak seedlings survive after being planted, their yield will be dreadful; they not only consume too many nutrients but also compete with other healthy seedlings for nutrients, doing harm with no benefit. 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 the seedlings are planted, 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 soil surface temperature and promote seedling growth. At the same time, it can also effectively prevent the invasion of pathogens, lower the disease rate, 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 you can appropriately increase the proportion of potassium fertilizer to ensure the swelling of the roots and stems.
The above is a brief introduction to sweet potato planting techniques; the environment for growing sweet potatoes is very simple. However, sweet potatoes grow relatively slowly, and although they do not need growers, all preparations need to be made before planting. The early growth of sweet potatoes is very important, and I hope everyone will pay attention to it. That is all for today's introduction.
