The main means of planting sweet potatoes is transplanting. It is also possible to directly plant sweet potatoes, commonly known as "laying eggs with melons", but the yield has no obvious advantage compared with transplanting planting, and it wastes a lot of melon seeds and is laborious to plant. Therefore, the cultivation of sweet potatoes is basically a way of transplanting. Sweet potato is a kind of food with high nutritional value, which contains sugar, protein, diosgenin, potato brass, vitamins A, B, C, E, dietary fiber, carotene, calcium, selenium, copper, iron, potassium and other elements. And fresh seeds. So there are many shortcomings. Sweet potato rarely blooms and bears seeds in the north, so it is generally propagated by sweet potato roots. But sweet potato flowering is very common in the south, because sweet potato flowering is affected by temperature and sunshine, even if it is the same variety.

When the temperature and humidity remain constant. We can plant it again in spring. In autumn, you can also cut long sweet potato seedlings into sections and raise them in greenhouses. When spring comes, you can cut long sweet potato seedlings into appropriate lengths and plant them in the ground. After sweet potatoes sprout or bloom, farmers will pinch them off. Why? Because it consumes nutrients, the superior and the inferior are eliminated in agricultural production, and there are few sweet potato varieties that bloom and bear seeds. Most of them will use sweet potato mother seeds to raise seedlings in seedbeds, and then transplant sweet potato seedlings into the fields. In rural areas, there is a saying that "the husband and wife of sweet potato blossom are separated". It can be seen that, like bamboo flowers, sweet potato blossom seems to be a bit abnormal or even unknown. However, this is not the case. It is normal for sweet potatoes to bloom in some places, but it is rare in some places. Sexual reproduction of sweet potato refers to the reproduction with seeds. Because of the complexity of sweet potato inheritance, the offspring of common seedlings will have complex segregation phenomenon, which is difficult to be directly applied in the field except for breeding new varieties. Some crops can use their own vegetative organs, mainly leaves, roots and stems to reproduce the next generation. In agricultural production, it can survive and develop normally by cutting, transplanting and grafting. Our common crops are sweet potato, sweet potato and potato.
