How to manage the prosperity and growth of sweet potatoes

Sweet potato is a very common food crop in China, which has a very large planting area in our country. However, although the sweet potato planting method is simple, there are often many problems affecting the yield and quality of sweet potato when planting sweet potato. Prosperous growth is one of the very common problems. So how to manage the prosperous growth of sweet potatoes? The following editor will give you a brief introduction, let's have a look!

1. Rational fertilization

During the growing period of sweet potato, we should apply sufficient fertilizer to provide adequate growth nutrition for sweet potato. If the fertilizer is not applied properly, it is very easy to cause the sweet potato to flourish. When applying fertilizer, we should pay attention to the balanced fertilization of both above ground and underground parts. The underground part should be mainly crack fertilizer to avoid cracks in sweet potatoes. When fertilizing the aboveground part, the fertilizer should be based on phosphorus and potassium fertilizer, and urea can be added appropriately. The application of nitrogen fertilizer must not be overdone. Excessive application of nitrogen fertilizer is the main key reason for the prosperity and growth of sweet potatoes.

2. Reasonable control of prosperity

When planting sweet potatoes, in order to prevent the excessive growth of sweet potatoes, we should properly spray some health control agents before sealing the ridges of sweet potatoes. Power control agents can be used uniconazole, dwarf and so on. To control the dosage, a small amount of spraying about 3 times can effectively inhibit the growth of stem vines, reduce nutrition consumption, and promote the expansion of potato blocks. When applying the control agent, we should apply it reasonably according to the growth of sweet potato plants. Do not spray too much, to avoid sweet potato stop growing, self-defeating, but affect the growth and development of sweet potato.

3. Lift the vine properly

When the sweet potato is growing, we should do a good job of vine lifting according to the actual situation of the sweet potato plant. The operation method of lifting vine is very simple, just lift the stem vine of sweet potato plant up a little. The main purpose is to keep the lateral roots of the plant out of the soil and prevent the lateral roots from continuing to grow. And it can also achieve the purpose of drying the ridge soil and improve the soil permeability. However, when lifting the vine, we should pay attention to the weather. It is not possible to turn the vine after it rains. Otherwise, it is easy to lead to stem and leaf damage, affecting the distribution of stem and leaf, thus reducing plant photosynthesis and reducing the yield of sweet potato.

4. Water management

The drought tolerance of sweet potato is relatively strong, the requirement of water is not high, although a certain amount of water is needed during the growth period. But remember not to water too much, and if there is stagnant water, discharge it out of the field in time. Prevent stagnant water from causing root retting of sweet potato plants, resulting in lack of oxygen in the roots, affecting nutrition and water absorption. Avoid stem vines absorbing too much water, resulting in overgrowth, thus affecting the normal growth of sweet potatoes. Then it is necessary to appropriately increase the proportion of potash fertilizer and concentrate the nutrition on the sweet potato block to promote the expansion of the sweet potato block.

The above is a brief introduction to how sweet potatoes need to be managed. That's all for today's introduction. This article is for reference only. I hope it can help you all.
