What causes the planting of sweet potatoes and the discovery of many cracked sweet potatoes at the t

Personally, I think it's because it's too shallow when planting, so a lot of sweet potatoes are cracked when harvested, because that's how sweet potatoes were grown in my family when I was young.

Because sweet potatoes grow too big, they are too nutritious, so that the body can't absorb the nutrients before they crack.

First of all, it may be due to insufficient moisture, which leads to dryness and cracking. The second possibility is that because of pests and diseases, the disease itself occurs, and it is necessary to prevent it in advance and detect it in time. The third possibility is that the harvest time is too late and the fruit is ripe.

This is most likely due to over-fertilization, which causes the sweet potatoes to burst when the rain falls. It may also be caused by the soil being too hard.

It may be that the soil is not well vented, it may be that there is a lack of organic fertilizer, and sometimes the watering and wet fertilizer are not reasonable, which can also lead to such results.

Every time farmers harvest in the autumn harvest season, they are often prone to cracks in sweet potatoes. Will cracks in sweet potatoes affect the quality of sweet potatoes, but also affect the yield of sweet potatoes, and also directly affect the economic benefits of farmers. The reason why there are so many cracks in sweet potatoes may be due to soil reasons, nutrient reasons, or uneven distribution of water, so the only thing farmers can do is to prevent them in advance.

There are many cracks on the body of sweet potatoes, which are probably due to the sweet potatoes themselves, and it may be that farmers have bad varieties when selecting seeds, so they are not very sensitive to the surrounding environment. Some sweet potatoes are actually early-maturing varieties, so the skin is relatively thin, and in the later stage, the fruit cracks due to so many factors. And the soil is buried under the soil in the process of growth, if the surrounding soil can be fertile and loose, it is more conducive to the growth of sweet potatoes, but if the soil is long, if the time is not turned, it will be very easy to harden, and then the sweet potato in the air permeability is relatively poor, the skin is easy to crack.

In the process of sweet potato growth, the lack of oxygen molecules in the soil is also one of the reasons for the cracking of sweet potatoes, such as the lack of calcium and boron in the epidermis of sweet potatoes. The reason why sweet potatoes are deficient in calcium may be because of drought, or because there are too many nitrogen fertilizers and potassium fertilizers, and the lack of boron in the fruit means that the usual potassium fertilizer is used too much, which affects the absorption of boron in sweet potatoes, and then there will be a lack of boron in the soil, and the sweet potatoes will crack. <>

When sweet potatoes are growing, water must also be sufficient, especially in the place where sweet potatoes are grown, if there is a long-term drought or a sudden flood, it will be dry and wet for a while, which will cause the flesh inside the sweet potato to grow rapidly, and then the outer skin will be squeezed, and then it will be broken and cause cracking. And because sweet potatoes are buried in the ground, they are very likely to attract some pests and diseases, such as needleworms, which can also cause sweet potatoes to crack.

It may be that the variety is not very good, it may be that the soil is not suitable, it may also be that the fertilizer is not correct, or it is watered too much, so that the sweet potato grows too fast, so it will lead to a lot of cracks.

I think the current cracks are because they grow relatively well, and the development is relatively large.

It may be due to the fact that the sun is exposed to too much heat. Generally, when growing sweet potatoes, you need to build a shed.

How do cracked potatoes come about? First, the soil is hard; Second, the soil has no gradient and does not brush water; The third is excessive fertilization. The specific reason is that sweet potatoes are planted in soil without gradients, and due to excessive fertilizer, when the rain falls, the sweet potatoes in the soil grow violently and burst.

Sweet potato infection can also lead to cracks in sweet potatoes, which affects the appearance, due to the influence of the weather, there is a lot of rain, which gives a lot of bacteria a chance to grow, so many insects have the opportunity to eat in sweet potatoes! That's how sweet potato cracks come about!

<> there are early and late ripening, for example, some early-maturing sweet potatoes have a slightly thinner skin, and the skin is thinner, and it is more sensitive. There are a large number of cracked potatoes planted in rural areas every year, among which there are three reasons, one is heavy cropping, the land is too hard, the second is the lack of seedlings, and the third is the sudden heavy rain in the later stage of the drought.

Sweet potatoes are highly adaptable, have less strict requirements for soil, are easy to cultivate, and are easy to manage. However, when the sweet potatoes are picked, it is inevitable to be depressed in the face of cracked sweet potatoes, especially some sweet potatoes that have cracked into strange shapes. In the process of sweet potato cultivation, there is often such a phenomenon, the sweet potatoes that grow very well, but when they are about to be harvested, they crack, and in serious plots, the cracking rate of potato blocks can reach more than 40%, which seriously affects the yield of sweet potatoes.

If you want to have fewer cracks in sweet potatoes, they are in good condition and have high yieldsIt is necessary to pay attention to the use of well-rotted organic fertilizer, and also pay attention to the use of micro-fertilizer。I remember when I was a child, the area of sweet potatoes planted in the village was still very large, and at that time, people often fed some cattle and sheep, and naturally they would make their dung.

It is best to choose a sandy soil with loose topsoil, good drainage, rich in organic matter, and deep soil layer for sweet potatoes. Soils with excessive sandiness should be improved by adding organic fertilizer and mixing clay soil. Although the soil is heavy and clayey, although it has strong water retention, it is not conducive to the formation and expansion of root tubers.

During the growth of sweet potatoes, potassium fertilizer is the largest, followed by nitrogen fertilizer, and phosphorus fertilizer is the least.

This is because when planting sweet potatoes, you don't pay attention to the protection of sweet potatoes. So after a long period of influence, it leads to a large number of cracked potatoes every year.

It is because sweet potatoes lack moisture and are relatively dry, and because the sun often shines, cracks will appear.

Because it grows too big, the sweet potato is stretched out so much that it cracks.

If you want to harvest sweet potatoes, what about the sweet potato seedlings on it? Sweet potatoes are cut from the ground before they are harvested. The shaving sweet potato seedlings can be planted by cuttings.

When mowing the ground, it is cut with a sickle, sweet potato, and sweet potato vine with a sickle, so that only one dried sweet potato is left on the branch of the sweet potato skin, and then the yam is soaked in the ground under a tree with a large branch, and the sweet potato chips are dug out and picked up from the ground in the back.

This kind of work does not look tiring, but if you keep working with your head down, your back will hurt after a long time. I remember when I was a child, I cut vines, had a short break, and always cried so much that my back hurt. While digging sweet potatoes, Dad said, the child ** has a waist!

In the countryside, it's a buzzword that kids don't have waists, but there's no reason why Dad is just joking with me. I remember my father once told a story about a child who had back pain when he cut off the vine.

The father said that the child had no waist and would not let him rest. As a result, the child cut for a while, found a rattan sickle tied to his ankle, and dragged the rattan pass step by step, when his father saw that he finished training, how could you work so hard, you are so stubborn, you can't cut your waist in! The child said, you can say that the child has no waist, I can only tie the son around the neck!

Father coaxed us with these funny stories to make us feel welcome and feel Father's kindness even in fatigue. In any case, sweet potatoes are traditionally harvested by hand before cutting the vines.

However, now the scale of planting Gankai's potatoes, often mostly using the technology of sweet potato seedlings returning to the field, smart people invented a sweet potato seedling killing machine, which can directly break the sweet potato vines to the field, and reuse the machine for sweet potato harvesting, which greatly reduces the labor intensity. Sweet potato seedling killing machine, generally equipped with a four-wheel tractor or walk-behind tractor to use, under the traction of the tractor, the use of special blades for high-speed operation, negative pressure balance Sun Yu will suck up the ridge seedlings at the bottom, so that the high-speed running blade will crush it. The utility model discloses a compact structure, good mobility, stable work, strong applicability, simple maintenance.

Sweet potato seedlings can be cleaned at one time.

The outer skin of the sweet potato is wrapped in the sweet potato tuber, belonging to the outermost layer of tissue, the first crack of the sweet potato cracking must be the sweet potato skin, the common manifestation is a red Jiandan potato tuber is full of cracks, the cracks are very shallow, you can see the flesh inside, after a period of cracking, the cracked gap will grow a layer of membrane, this membrane will repair the wound, and finally the surface of the sweet potato tuber will form in all directions, similar to the road, and is a sunken line. After planting sweet potatoes in March, there will be a period of humid weather, this time is the period when the sweet potato vines are prosperous, but after Qingming, the weather begins to be dry and hot, and this time is the period of growing sweet potato roots, sweet potato roots grow slowly in this dry weather, after the sweet potato roots experience 1 month of growth, the sweet potato roots also grow relatively large, it is also at this time, the weather suddenly enters a 1-week rainstorm period, and the sudden continuous rainstorm makes the originally arid land, Suddenly, the water skyrockets, the sweet potato begins to absorb water quickly, and the center of the sweet potato root with the most vigorous vitality will grow and expand rapidly, while the growth rate of the outer part cannot keep up, and it will be disturbed by the cracking, and the sweet potato cracking phenomenon will occur.

Sweet potato is a warm climate to grow vegetables, spring every April, as the weather warms, people start to get busy, sweet potato planting sweet potato vine cuttings usually to grow, sweet potato vine vines, must use a sweet potato (more technical term is sweet potato root) seedlings, choose sweet potato roots, people will choose those good sweet potatoes whose epidermis is not damaged or lightly damaged, and have not been eaten by insects, rather than those that have been damaged and eaten by insects.

Bad sweet potatoes can't grow? Choose! Understand the distribution of the eyes, with ridges, grass as the cover of potato seedlings from bad sweet potatoes In fact, some of the "bad" sweet potatoes are very poor, cut obviously, soft, and you can also see that there is a mistake, and not for the seedlings is the normal method, and the "bad" part of the sweet potato skin is damaged, the surface of the worm, soft, sweet potatoes are planted less, and there are no better sweet potatoes to choose from, such "bad sweet potatoes" can be planted well with seedlings, but are often ignored and not valued; Of course, if you want such a "bad sweet potato" seedling to grow seedlings and grow well, you must also pick a sweet potato, and pay attention to waterproof soaking after sowing.

First of all, the choice of "bad sweet potato" is the most critical, which is related to the germination and growth of the eyesThe distribution of sweet potato eyes and the germination of germinating sweet potatoes are actually the germination of the bud eyecortex, similar to the germination of potatoes; Sweet potatoes have multiple eyes, which can be said to be distributed in the body, but the eyes are relatively shallow, even invisible, and the germination of the eyes has its own rules: although there are many eyes of sweet potatoes, but in fact, the growth of seedlings is not all, a few, more than ten or twenty, etc.; It is generally the first half of the sweet potato that sprouts and grows, and then the middle and the lower half.

Can you use the "bad sweet potato", apparently sprouting from the top of the sweet potato at the top of the **? Autumn and winter sweet potato harvest, dig out the sweet potato, we have to break the stem, the connection between the long sugarcane and the sweet potato leaves, the rather thick root is the main trunk of the sweet potato in the expansion process to the sweet potato nutrition hydration, is directly connected to the sweet potato is the upper part of the sweet potato, there is a short, corresponding to the other end of the root of the sweet potato bottom, when we are on the ground, planting sweet potato roots will grow sweet potato at both ends, and the priority position for germination and growth is the upper part of the sweet potato eye, if the base fertilizer is sufficient when planting, with the absorption of nutrients by the root system, The middle and lower parts of the sweet potato eye will sprout and grow; Of course, the sweet potato itself is a nutrient concentration, and if the nutrients themselves are insufficient, the lower part and the lower part will also sprout and grow.

Cracked sweet potatoes should not be used as seed potatoes. Because cracked sweet potatoes lose their vitality, it is difficult to grow alive.

I don't think cracked sweet potatoes are okay. Because cracked sweet potatoes produce a lot of bacteria and are also prone to spoilage.

No, because cracking will destroy the vitality of sweet potatoes, and it is difficult to grow such sweet potatoes.

It is very important to plant sweet potatoes and choose seed potatoes, if you choose small potatoes to cultivate sweet potato seedlings, due to the limited nutrients of the mother potato, then the sweet potatoes it grows are thinner and not stout, although it is said that the potatoes are smaller after transplanting and planting, and affect the yield, but because they are born in the process of sweet potato planting, they often encounter some problems, due to the perennial sweet potato planting experience, we can also master a lot of sweet potato planting technology. In the process of growing sweet potatoes underground, the phenomenon of cracking occurs, the reason may be caused by the imbalance of nutrients with fertilizer, water and temperature, and the lack of boron and calcium in the soil fertilizer during the expansion period is easy to cause cracks in the outer skin of the potato pieces, or the long-term drought suddenly encounters heavy water, which will cause the rapid growth of potato flesh, resulting in the growth rate of the epidermis slower than that of the internal epidermis, resulting in cracking.

<> most cases of sweet potato cracking, that is, the flesh inside the potato chunk grows rapidly, and the skin of the potato chunk does not catch up, and finally the potato skin is broken, and cracks or cracks appear. The main reasons for the imbalance in the internal and external growth of sweet potatoes are: first, better water and fertilizer conditions, 2Soil compaction is not loose:

The soil is compacted and not loose, which makes the soil less permeable and increases the chance of sweet potato cracking. Solution: Before planting, use 10% avisezole phosphorus to release water quid roots, and apply avi and chlorpyrifos into the soil layer to prevent and eliminate the pest.

I have grown sweet potatoes and harvested a lot of cracked sweet potatoes, and I have found that cracked sweet potatoes are always harvested in the corners of the field, and in the dead soil, and there are almost no cracked potatoes in the living soil in the center of the earth. Analyze the mouth from the inside to the outside and from the outside to find out the cause and prevent the recurrence of cracking. According to my observation and research, the reason why sweet potato cracking is caused from the inside to the outside is three factors: moisture, nutrition, and weather; The reason for the outside-in is that the soil fertilizer and water are too large during the soil expansion period, which is also easy to cause cracks in the outer skin of potato pieces.

4. During the growth period, the moisture is uneven, and the long-term drought suddenly encounters heavy water, which causes the rapid growth of potato meat, and the growth rate of the epidermis is slower than that of the inside and breaks the epidermis.
