Do I need to turn the vine when planting sweet potatoes? Experts give answers
In recent years, it is estimated that many people have found that the number of people growing sweet potatoes has begun to increase. In the past, sweet potatoes were grown more in rural areas, because sweet potatoes could be used as a coarse grain to fill the stomach, and also as a diversified food as a feed for livestock. But nowadays, there are not many people who raise pigs in the countryside. Why do so many farmers want to grow sweet potatoes again?
In fact, there are still farmers who want to grow these two types of sweet potatoes:
1.Make hay. Over time, the variety of products surrounding sweet potato processing began to increase. For example, sweet potato flour, biscuits, etc. With demand comes the need for more sweet potato raw materials. In addition, the area of sweet potatoes planted in the past was small, the yield was not high, and the ** was average. One acre of land can only make that much money. However, nowadays with better sweet potato varieties, higher yields, and most importantly, higher grades, farmers can make money growing sweet potatoes.
2.Edible. Over the years, there has been a growing demand for sweet potatoes. One of the reasons is that sweet potatoes are delicious. Due to the emergence of new varieties of sweet potatoes after the improvement of sweet potatoes, many people like to eat sweet potatoes. In particular, the sweet, soft and glutinous boiled sweet potatoes are loved by adults and children. It is precisely because it is so delicious that many farmers have started to grow some at home for their families to eat.
As more and more people grow sweet potatoes, they naturally worry about how to produce high yields. In the early years, sweet potato growers did not pay attention to the importance of management, and almost always let the sweet potatoes grow on their own. As a result, sweet potato yields are sometimes high and sometimes low, which is not accurate. In fact, in order to have a high yield of sweet potatoes, certain techniques must be mastered. Whether or not to plough the vineyard after planting sweet potatoes is a matter of science. Let's talk about this issue together.
When planting sweet potatoes, should you flip the vines?
The answer is not necessarily! Here we must look at this from two aspects:
First of all, we need to know what it means to transform the vine and why it should be done.
Flipping a vine is simply lifting a creeping sweet potato vine up and flipping it so that the leaves are facing down. The reasons for this are as follows.
When planting sweet potatoes, it is usually necessary to turn the vines when the sweet potato seedlings are growing vigorously. At this time, it is obvious that the sweet potato seedlings are growing well. If we don't intervene and control vigorous growth, we will end up with sweet potato seedlings that only produce vines. Even if sweet potatoes produce sweet potatoes in the future, the seedlings will absorb too many nutrients, resulting in insufficient nutrients for the growth of sweet potatoes, resulting in a situation where the vines are small and the number is small.
At this time, the vine can be transformed to remove the adventitious roots of the sweet potato vine from the soil to block the supply of a large amount of nutrients to the adventitious roots, and the flipping of the leaves will also cause the photosynthesis of the leaves to slow down, further preventing the emergence of the vigorous growth of the sweet potato vine. At this time, the application of phosphorus and potassium fertilizer can promote the transformation of sweet potato growth, which is conducive to the growth of sweet potato.
There are times when the vines are turned, and there are naturally times when the vines are not turned. In this case, the reason for not turning the vine is that the seedling itself is not vigorous enough, and the plant growth is average. In this case, in addition to turning the vines, it will also cause the seedlings to supply nutrients slowly, resulting in a decrease in the yield of sweet potatoes and their lack of growth.
Therefore, when planting sweet potatoes, it is necessary to decide whether the vines need to be turned according to the actual situation. If the planting area is large, it is difficult to control the growth of vines. In this case, a drug can be used to control the wangchang.
