What are the benefits of the inverted seedlings cultivation method when growing sweet potatoes?

Sweet potato flat upside down planting has two advantages: first, the contact surface between the seedling and the soil is large, which is conducive to the rooting of sweet potato and can obtain water and nutrients; Second, the seedlings are less exposed to the outside, which can avoid the problem of vine growth. Compared with sweet potato planting, the traditional planting method has a long history and has a complete solution when there is a problem, while the new planting method has a high yield probability, but lacks a systematic solution when the problem occurs.

Agricultural planting should not only solve the problem with probability, but also use advanced planting technology and management methods to increase yield.

The cultivation quality of large ridge double row is higher on the flat land with good soil quality and loose soil layer. The ridge spacing is 90-120 cm, the height is 30-35 cm, the plant spacing is 25-30 cm, and there are two rows of sweet potato seedlings on the ridge. The density is determined according to the requirements of the variety, generally reaching 4000 plants per mu, and the yield of small rows and single rows is increased by about 10%.

The reason for the increase in yield was the increase in the spacing of the double-row plants in the large ridge, the increase in density, and the reasonable distribution. In the north, where the frost-free period is short, the double row of large ridges is also suitable for the application of technologies such as plastic film mulching.

Sweet potato is a food and cash crop with high yield and strong adaptability. It is highly nutritious and widely cultivated in most parts of China. As the old saying goes:

Gu Yu planted sweet potato seedlings, and a large basket could be harvested from one tree. "As long as the temperature is stable above 15, the sweet potato seedlings can be transplanted into the field in sections. Sweet potato seedlings can be inserted vertically, horizontally and obliquely, among which oblique insertion is the most commonly used method.

Sweet potato seedlings have the characteristics of strong drought resistance and high yield. Today I will teach you a new method of sweet potato cuttings, that is, "inverted seedlings" transplanting sweet potato seedlings.

This cultivation method makes the yield of sweet potato more significant, which can increase the yield by more than 30% compared with the traditional "oblique insertion method". I am very optimistic, many people explain that "upside-down sweet potato" is to insert sweet potatoes upside down in the soil, theoretically it also makes sense, the stems and leaves of sweet potatoes will grow slowly, because the direction of absorbing water and nutrients is reversed, that is, the plant will not have excessive growth of stems and leaves, so that the nutrients of the plant can be concentrated to supply the growth of sweet potatoes, and finally achieve the purpose of high yield.

But is that really the case? When planting sweet potatoes, the transplanting method of sweet potato seedlings is very important. Experienced farmers know that planting sweet potato seedlings must pay attention to methods.

If the method of planting sweet potato seedlings is not correct, the planted sweet potatoes will only grow seedlings and will not bear sweet potatoes. Farmers call this phenomenon "potato runs". To put it simply, when planting sweet potato seedlings, if the roots of the sweet potato seedlings are directly inserted into the soil, this planting method is incorrect, and the roots of the sweet potato seedlings will not grow sweet potatoes.

When this sweet potato seedling is inserted upside down, its vines cannot grow as white as they do in the soil. Once the vine can't grow white, the nutrients that the vine can consume will be reduced, so that the tuber can get more nutrients. When the potato wedges are nutritious, the potato wedges will naturally grow large.

The correct way to plant sweet potatoes When planting sweet potatoes, now some sweet potato ridges must be made in the ground, and the dragon ditch must be wide. To put it simply, the spacing of sweet potato seedlings must be wide, and the sweet potato seedlings are too dense to grow sweet potatoes.

Inverted seedlings are placed horizontally into the soil instead of the previous oblique placement into the soil. It is true that yields can be increased because inverted insertion increases the contact between stem and leaf and soil, enabling stratified tuber setting and improving the size and quality of tubers.

Inverted seedlings are planted to bend the middle of the signature downward into the soil, inverted seedlings can improve the yield, the yield will be greatly increased, which is conducive to sweet potato stratification to relieve the heat, to ensure that each part of the sweet potato can find sweet potato, so its yield will be increased.

When planting, the seedlings are buried in the soil, and then the leaves are pruned off, and there are only two or three leaves on the exposed branches. Yes, you can invert the seedlings to make the rhizome of the sweet potato have a better development, and the yield of the sweet potato can be better.

1. Inverted insertion method: inverted insertion refers to the bottom of the boat type cutting, that is, the sweet potato seedlings are transplanted horizontally into the soil, and the part buried in the soil is deformed at the same time to make it a "U" shape, or a boat type, and the length of the sweet potato seedlings is required to be about 25-30cm. 2. Function:

Sweet potato seedlings transplanted inverted can inhibit apical dominance, prevent plant growth, and have higher survival rate and yield.

First, the correct way to insert sweet potato seedlings upside down

1. Inverted insertion method.

1) Inverted cuttings refer to the bottom of the boat cuttings, that is, the sweet potato seedlings are transplanted horizontally into the soil, and at the same time, the part buried in the soil is deformed to make it a "U" shape, or a boat shape, only a small part of the leaves are exposed at the top of the plant outside the soil.

2) The length of sweet potato seedlings used for inverted cuttings is required to be about 25-30cm, and the depth of burial is about 5cm.

2. Function:1) The length of sweet potato seedlings used for inverted cuttings is longer, and each node of sweet potato seedlings can produce sweet potatoes, so the longer the sweet potato seedlings, the more potato setting points, and the yield is naturally higher.

2) Sweet potato seedlings transplanted inverted can inhibit the top dominance, prevent the plant from growing vigorously (only grow vines, not tubers), and avoid the plant consuming a lot of nutrients and water.

3) The survival rate of sweet potato seedlings transplanted by inverted transplantation was higher, and it was conducive to the stratification of sweet potatoes.

Second, how to plant sweet potatoes

1. Transplanting time.

In the suitable transplanting time, the earlier the transplanting, the more fully the advantages of infinite reproduction and growth of sweet potatoes can be fully exerted, increase the accumulation of substances, prolong the growth period of plants, make stems and leaves appear early, improve the photosynthetic capacity of crops, and promote plant branching. In general, transplanting is carried out when the local temperature is stable above 15°C and the temperature of the shallow soil layer reaches 17-18°C.

2. Transplanting method.

Transplanting was carried out using the inverted insertion method. Method: Transplant sweet potato seedlings horizontally into the soil, and at the same time bury the part in the soil in a "U" shape, or boat shape, with only 2-3 leaves exposed from the top of the plant.

3. Planting density.

If it is planted in two rows of high ridges, the yield will be increased by about 24% compared with that of ordinary single-row planting of high ridges. Specific methods: ploughing depth 25-30cm, ridge height 25-30cm, ridge width 100-120cm, ridge spacing 80cm, ridge surface cross planting double row seedlings, row spacing 40-50cm, plant spacing 26-33cm.

When cutting cuttings and vines, it is necessary to choose the seedlings and vines that grow strong and strong, the root system is developed and there is no loss, diseases and pests, after the vine is harvested, the stems and vines should be cut into small sections with 2-4 nodes according to the method of cuttings, and the leaves on the short vines should be removed, the flat cuttings method is to put the sweet potato vine seedlings about 25 cm long, the stem nodes of the vine seedlings, after placing them horizontally, they are planted into the soil about 5 cm deep, this vine method produces more potato pieces, the yield is high, the soil layer is shallow and the drought resistance is weak.

<>l interpolation. This method of cutting vines is also the more commonly used cultivation method of sweet potato, and the oblique planting method is similar, it is also at the top of the ridge to open the vine hole first, but the hole is slightly longer, and then the lower part of the potato vine is laid flat and buried in the soil, and the upper part of the potato seedling should also be returned when pressing, the purpose is to cut the sweet potato seedling cultivation. In order to achieve high yields of sweet potatoes, the key is to cultivate strong sweet potato seedlings, and the best sweet potato seedlings should have thick stems, short internodes between leaves, and seedlings should look fat.

Observe when the sweet potato seedlings grow to about 13 to 15 cm.

Buried leaf cutting: that is, the stem and vine leaves are buried in the soil, the tip of the seedling is exposed 3 leaves, and the other leaves are buried in the soil, which is mainly suitable for planting sweet potatoes in the dry season, which can reduce foliar transpiration, has obvious drought resistance and seedling protection effect, and the planting depth is 3-7 cm is appropriate. This method is easy to insert, labor-saving, close to the soil surface to produce large potatoes, the lower part of the potatoes are few and small, the size of the tubers is uneven, but the number of potatoes per plant is more and larger than that of straight insertion.

If it can be planted reasonably densely, high yields can be obtained.

Method: The straight insertion method is relative to the oblique insertion method, but the branches of the cuttings are shorter. Pros:

This method also has a high survival rate and is also drought tolerant, and the sweet potatoes grown by this method are larger. Transporting the vines to the field where cuttings are needed, because the field has been cultivated and the soil is very loose, so it is suitable for cuttings; In general, the field is ploughed into a furrow shape, and sweet potato seedlings are cut into the raised ravine.

The planting methods of sweet potatoes are: sweet potatoes are cut into cubes. Seed with seeds.

There is also the way of cuttings. When cutting sweet potatoes, pay attention to the selection of cuttings, and the branches must be strong, vigorous and healthy. Also, the land chosen for cuttings must be fertile enough.

And after cuttings, you should water more and water the land thoroughly.

The first point, soilless cultivation, seed cultivation, and branch cultivation are very important cultivation processes, and the fourth point is that the speed of transplanting should be mastered in the process of cultivation, and the fifth point should be in my regular watering thinking, which are very important.

Sweet potato cuttings can reduce costs. Sweet potato is a kind of vegetable with underground root edible organs, which is resistant to high temperatures, and the planting methods generally include cutting planting and seedling planting methods, because the sweet potato growth period is also longer, relatively speaking, seedling transplanting has many advantages over tuber planting. Sowing seeds first can reduce costs:

Sweet potato and potato seedlings, when the sprout grows to a suitable sowing height of 20 cm, the seedling and germination can also grow taller, and can also be used for sowing, for large-area sowing, it can also save a lot of costs, relatively speaking, the income will also increase.

It can improve the uniform survival rate of potato seedlings: When potato planting, it is caused by poor soil moisture, uneven soil moisture content or uneven land preparation, or because some tubers do not survive due to severe dehydration and drought, or tubers do not survive due to soil moisture, resulting in incomplete guide rails, insufficient occupancy per unit area, which directly affects production. Air destruction shortens the maturation time and goes to market in advance:

Due to the long growth period of sweet potato, the planted seedlings grow and mature earlier than the tuber, which can also avoid the cold climate in autumn, because the sweet potato with a ground temperature of 15 ° C will stop growing, and the potato chips will be chilled down below 10 ° C for a long time, so the planted seedlings can be marketed in advance, and can avoid diseases at low temperatures, reducing quality and taste.

As for whether the tuber of the preservation artificial planting method is suitable for the planting method, it still needs to be developed and utilized, but for seedling planting, due to the nature of the sweet potato seedling itself, the fiber rhizome is delicate, the stem and leaf fiber content is thin, the stem and leaf lack toughness, the seedling raw fiber is easy to mix together, and various attributes are limited, there is no machine tool to launch the planting method at present, and even if the machine tool can plant the seedling, the soil needs to be cultivated artificially, and the cost is increased.

Sweet potatoes are a kind of thing that many young people like to eat nowadays, but most sweet potatoes are also eaten as snacks, especially baked sweet potatoes that many people like. Eating more sweet potatoes has anti-cancer effects. However, the older generation of people don't like to eat this, after all, people at that time were tired of eating sweet potatoes.

From childhood to adulthood, the villagers in Qingshui Pond saw that they also planted sweet potatoes, and all the methods, without exception, were to first put the seeds of the seed potato spine into the ground culture medium.

A lot of vine seedlings grow, and then the sweet potato vine seedlings are cut and planted. Why do sweet potato cuttings grow? Clearwater believes there are several main reasons.

Using a U-shaped cutting, a small part of the top of the plant is exposed, and the rest is buried in the soil. Leave the roots exposed. This can increase the yield, allow the sweet potato to grow effectively, and improve the quality of the sweet potato.

First of all, you should choose fertile soil, and then you should also control the temperature, transplant in time, be sure to improve the survival rate, and do a good job of drainage and ventilation. The purpose of this is to increase the yield of sweet potatoes, avoid rotting, and increase the growth rate of sweet potatoes.

Pay attention to the depth, and then master the right time, be sure to master the corresponding skills, be sure to protect the roots, but also to ensure the fertility of the soil, so that you can improve the yield and quality of crops, and avoid pests and diseases.

Sweet potato, also known as sweet potato, sweet potato, sweet potato, sweet potato, sweet potato, yam, sweet potato, golden potato, etc., is a millet plant of the family Spiraceae.

To cultivate sweet potato seedlings, horizontal cuttings, oblique cuttings and vertical cuttings can be used when cutting sweet potato seedlings, among which the 45-degree oblique cutting method is more common. This method has a high survival rate, good drought resistance and high yield. Today I'm going to talk about "inverted seedlings" transplanting sweet potato seedlings.

Compared with the "oblique seedling", the yield of sweet potato cultivated by this method can be increased by 30%, and the yield increase effect is more obvious.

Many people may think of cutting the stem of a sweet potato upside down, that is, cutting the old part upwards and the young part downward. In fact, this way of understanding is not entirely correct.

When the temperature and humidity of sweet potato seedlings are suitable (the average daily temperature is greater than 16, and the soil moisture is about 75%), the survival rate of sweet potato seedlings is relatively high. The survival rate of old stems of sweet potatoes is very high, but if you plant in the spring, if you put the roots of the sweet potato seedlings upwards and insert the tender parts of the sweet potato seedlings (along with the leaves) into the soil, the seedlings are likely to die, and even if they survive, the slow seedling period will become longer, which is definitely not conducive to the increase of sweet potato yield.

The growth point of sweet potato seedlings is buried in the soil, which is not only easy to break, but also the seedlings will be weak. Completely inverted is only suitable for summer plugs. If the older sweet potato vine is inserted upside down, although the survival rate of the sweet potato vine will be very high, the sweet potato planted in this way is easy to flower and set seeds, and the sweet potato flower consumes a lot of nutrients in vain, which is not conducive to the expansion of underground tubers, and the yield of sweet potato will naturally be affected.

Why do sweet potato vines survive when they are upside down? This is because no matter how you plant sweet potato seedlings, sweet potatoes always "root on the knots and sprouts are growing". So what is reverse insertion?

It is a polysyllabic word. Not "handstand", but "handstand". The so-called inverted transplanting method is actually a boat-shaped rice transplanting method.

Some of the seedlings in the soil are U-shaped, and a few leaves are exposed on top of the plant outside the soil. Inverted planting is actually bent planting, which is not burying the branches in the soil and exposing the roots.

The stems and leaves of the sweet potato (the part buried in the soil) should be pinched off and the petiole should be fingernail-length. Do not pinch the position of the seedlings, and then seal the soil and water, which can slow down the seedling stage and take root quickly.

Sweet potato seedlings are upplanted as the reason for high yields.

Reason 1: The sweet potato seedlings buried in the soil by the inverted insertion method are relatively long, and the length of the selected sweet potato seedlings is generally 25 30cm. Sweet potatoes can produce sweet potatoes at every node of a seedling, and the more growing points there are, the more sweet potatoes will bear.

Therefore, the number of sweet potatoes can be significantly increased by reverse planting, and the yield of sweet potatoes is naturally higher.

Reason 2: The sweet potato seedlings transplanted by the post-insertion method can inhibit the apical dominance, and the plants are not easy to flourish. Once the sweet potato seedlings are vigorous, they will only grow vines and no tubers.

Sweet potato vines consume a lot of nutrients and water, and due to insufficient nutrients, the tubers will not expand sufficiently, and the yield will naturally be lower.

A handful of sweet potatoes will be wiped out, and sweet potatoes will pile up" is not unreasonable.
