Matters needing attention in sweet potato planting

Sweet potato is actually the general name of many sweet potatoes, but because sweet potato is the most common in people's life, sweet potato later became another name for sweet potato. And now there are many new varieties of sweet potato, not only the yield has increased, but also the planting of sweet potato is a little different from before, so let's take a look at what problems we still need to pay attention to in planting sweet potato.

1. Planting time

Now the time for sweet potato planting is very extensive, it can be said that it can be planted with seasonal bacteria other than summer, but here the editor would like to remind you that it is the best planting time for each season, you can pay attention to it. This can increase the yield of sweet potato. It is best to plant in late March to early April in spring, at the end of August in autumn, and around October half in winter. Finally, when planting, we should pay attention to choosing cloudy and rainy days, so that the survival rate of sweet potatoes can be increased by at least 5%.

2. Planting method

There are many ways to grow sweet potato, but if we want to increase the yield, we'd better choose these cutting methods. Our first choice is horizontal cutting, which produces uniform sweet potatoes and a large number of sweet potatoes, but the only disadvantage is that they are not tolerant to drought. Second, we can use the direct planting method, so that the sweet potato is larger. Finally, we can also choose oblique insertion, so that the survival rate of sweet potato is the highest. Here, the editor would like to remind you that the sweet potato seedlings used for cutting are best cut into segments with five leaves, which is more conducive to its survival and growth.

3. Weeding and lifting vines

At present, one of the points that need to be paid attention to in the cultivation of new sweet potato varieties is weeding and vine lifting. After the sweet potato seedlings have survived, we need to carry out a thorough intermediate ploughing and weeding. The second is to carry out the last intermediate ploughing and weeding when the sweet potato seedlings grow to about 40 centimeters, and then during its tuber growth, our weeding is mainly manual weeding, so that weeding will not damage the growth of sweet potato. At the same time, it can also reduce nutrient digestion. The second is to carry out artificial weeding at the same time we need to lift vines to sweet potato seedlings, which can prevent vines from rooting and losing nutrients.

4. Hit the top and pick the heart

In the past, sweet potato cultivation also needed to top and pick the heart, but at that time, it was also necessary to remove some sweet potato seedlings in an appropriate amount, which can reduce the absorption of nutrients by branches and leaves, thus promoting the growth of tubers. now the new variety of sweet potato usually needs to carry out heart-picking, because its branches and leaves grow just right, not only will not consume a lot of nutrients, but also can better carry out photosynthesis and respiration. By picking the heart, the excessive growth of the main vine can be prevented, thus promoting the growth of lateral branches and reaching the standard of tuber expansion.

5. Water and fertilizer management

The growth of sweet potato needs to have sufficient water, in its growing period, we should keep the soil moisture at least about 60%, if the humidity is too high, it should be drained in time, otherwise it will cause sweet potato fruit and even rot. In the process of fertilization, we should not pay attention to the partial application of nitrogen fertilizer, which will cause the branches and leaves to grow and the sweet potato tuber can not expand.
