When is the best season to grow sweet potatoes?

However, transplanting sweet potato after the long summer solar term shortens its growth cycle and affects the natural yield to some extent. Now is the solar term in Grain Rain, as the saying goes, "Rain gives birth to a hundred valleys". At this time, the rainfall is sufficient and the temperature rises, which is a good season for planting sweet potatoes. Sweet potato can be planted as long as it comes out of the final frost period in spring, that is to say, it can be planted in North China Plain from April 25th to June 25th in summer, and it can be planted in both months. The sweet potato planted before June is called spring sweet potato, and the sweet potato planted in June is called late sweet potato. It was not until early winter that sweet potatoes were harvested in the first frost. After the first frost, sweet potato is very sweet after the leaves are frosted. The temperature difference between day and night before and after the first frost is large, so that the sugar of sweet potato can be fully accumulated. Sweet potato tastes good at this time.

When planting sweet potatoes, there is no need to fertilize. When you start planting, you just need to water them with clear water. When the sweet potato seedlings survive and take root, you can chase them with a little farmyard manure or urea fertilizer. When you want to plant sweet potatoes, you can add phosphate fertilizer, chase them again, and plant them after the sweet potatoes are harvested. In winter, a bowl of warm sweet potato porridge can probably solve all the troubles. Besides, baked sweet potatoes on the street are also popular snacks. When you are hungry, a hot baked sweet potato is sweet and delicious, satisfying everyone who is greedy.

However, the vines of sweet potato grow too vigorously, which wastes a lot of nutrients and affects the growth and expansion of sweet potato. If the vines of sweet potatoes are particularly vigorous, the underground potato pieces will not get nutrition and the yield will not be too high. Therefore, if sweet potatoes want to produce high yield, we should pay attention to controlling the prosperity.

Dig a ditch in the soil with a hoe, press the sweet potato seeds into the ditch, cover the sweet potato with mud, then pour an appropriate amount of manure on the mud, arch the bamboo slices on the sweet potato with bamboo, and finally cover the bamboo slices with a film, and press the film with mud at the edge to prevent the film from being blown up by the wind.
