What causes cracks when growing potatoes? How can it be prevented?

Potatoes, also known as potatoes, are a common ingredient, and there are many ways to eat potatoes, not only fried but also fried, and the taste is very good, so it is popular with many people. When many people grow potatoes, they sometimes find that the potatoes are cracked, and once the potatoes are cracked, it will not only affect the quality, but also cause losses to people. In order to better prevent and control potato cracks, it is necessary to find the cause of potato cracks.

During the growth of potatoes, if the tubers are expanding, at this time, if there is a prolonged rainy day, the tubers growing in the ground will absorb too much water, causing the tubers to grow faster, resulting in cracks. In addition, if there is no rain for a long time and the soil is particularly dry, it will also have a certain impact on the expansion rate of potatoes and slow down the expansion rate. It is mainly caused by the uneven supply of water, so it is necessary to pay more attention to the moisture condition of the soil during the growth period of potatoes.

Potato cracking is also inseparable from its variety, if the potato variety is not too good, then in the later growth, it will also cause the potato to crack. Therefore, when planting potatoes, it is best to choose high-quality varieties for planting. In addition, if the soil in which potatoes are grown is sandy, the surface of the potatoes can easily be scratched due to the large amount of sand and gravel in the sandy soil, and the large number of stones.

During the potato swelling period, these cracks deepen, causing the potato to crack.

Therefore, when choosing soil for planting, try not to choose sandy soil. You can choose some more fertile, loose and breathable soil to grow potatoes, so that the probability of potato cracks can be greatly reduced.

Causes of cracks, 1Reasons for the potato variety itself 2Influence of soil texture and fertility 3, Influence of climate 4, Insufficient cultivation practices 5, Effect of viruses 6, Effect of plant growth regulators, herbicides, etc.

How to prevent and control 1 select the right variety and suitable place, 2 scientific fertilization and water control, 3 timely mulching, 4 timely film removal, 5 prevention and control of pests and diseases.

It is likely that it is due to the variety, it may be affected by fertility, or it may be caused by high temperatures. Timely watering, but also pay attention to sterilization and disinfection.

This is the time of the potato, and when there are defects on it, it is usually caused by its malnutrition, and we usually have to apply potassium and phosphate fertilizers to him, so that he can grow well.

Potatoes are also called potatoes. One of the foods that people eat most often. It is also very common for potatoes grown in the ground to crack.

There are also a variety of reasons for potato cracking. Among them, the impact of rainfall and disease are the two main reasons. In addition, diseases are also an important cause of potato cracking during growth.

Causes of potato cracking. The first is uneven precipitation. During the potato growing season, if the potato experiences a drought for a period of time, but immediately experiences rainfall, the rhizome of the potato will grow rapidly, so that the rhizome will crack; Secondly, the impact of the disease.

In the process of potato growth, if part of the potato is affected by the disease and inhibits the swelling, the other part that is not affected by the disease will continue to grow, so that the phenomenon of cracking will occur; Finally, potatoes are fertilized unevenly. If you want to have a large potato yield, you need to fertilize the potato, and if the fertilization is uneven during fertilization, it will also lead to the difference in the degree of expansion of the rhizome of the same potato, resulting in cracking. <>

1. Uneven precipitation. Precipitation is an important factor in whether potatoes can grow well. If the growth of potatoes has been suppressed after a period of drought, but abundant precipitation is imminent, the rhizomes of potatoes will swell rapidly, leading to cracking.

Second, the impact of the disease. The rhizome of the potato affected by the disease will stop swelling, but the part that is not affected by the disease will continue to grow normally, and such uneven growth will cause cracking. <>

3. Potato fertilization is uneven. Potatoes also need to be fertilized when they grow, but if the fertilization is uneven, different parts of the same potato get different nutrients, and the part that gets more nutrients grows faster, but the other part that has no nutrients grows slowly, which will also cause cracking.

Potatoes, also known as potatoes, are rich in nutrients and have anti-aging effects. Potato is also a natural beauty product, has a good care for the skin, beauty and beauty effect, summer is easy to people's ** sunburn and tanning, potato juice has a very obvious effect on removing pigmentation. Potatoes also have the effect of **, it is the lowest fat content of all hunger-filling foods, so eating more potatoes every day can reduce fat intake and help **.

Potatoes contain vitamin C, food can affect people's mood, because it contains minerals and nutrients, which can act on human beings to improve their mental state, so eating more potatoes also helps to develop a good mood. However, potatoes contain a lot of starch, so diabetics should eat less or no potatoes.

<> many people may think that potato cracking is due to calcium deficiency, but this idea is actually wrong, calcium is only one of the reasons for his cracking. A comprehensive analysis of the causes of potato cracking has the following aspects. First, the reason for water supply, when the potato tuber begins to swell, if there is drought or lack of water, it will cause the tuber to be large and slow down, and if it encounters heavy rain or continuous rain to absorb water, the tuber will crack.

Second, the reason for the variety, potato tuber cracking has a certain relationship with the variety, the moisture content of the potato, the thickness of the skin, the sugar content, and the degree of development will affect the cracking of Shuhui, so in the production process, it is necessary to choose the varieties with moderate size and transportation resistance after batch. Thirdly, because of soil fertility, Maling soil is suitable for survival in sandy soils, and uneven fertility can also lead to potato cracking. Fourth, because of the high and low temperature, potatoes are suitable for survival at 15 to 18 degrees Celsius, and too high or too low temperature may affect potato cracking.

Fifth, the reason for the application of pesticides, as well as the improper use of fertilizers with excessive hormones, can lead to cracking of potato pieces.

In the cultivation process, if you encounter cracking, you must clarify the cause of cracking, and then choose the appropriate solution, make up for it in time, and minimize the loss.

Caused by uneven fertilization. Some blind areas of sprinkler irrigation and drip irrigation, such as the edge of the ground and the foot of the ground, often have uneven water and fertilizer, resulting in inconsistent expansion speed of potato pieces and easy to crack. In addition, if the top dressing is excessive, the tubers will grow vigorously due to too much nutrients, and cracking will also occur.

Growing too fast and nutrient absorption is not keeping up, pay attention to fertilizer and watering.

The seeds of potatoes need to have buds on the potatoes, and when cutting the pieces, it is necessary to ensure that each piece of potatoes has sprouts on it, and some pieces do not leave sprouts on them, so after planting in the soil, the potatoes will die, because it cannot grow normally. Poor preparation before potato planting is an important reason. The main aspects are as follows: first of all, the cutting area of the root block is too large, the seedlings after planting are too fragile, and the final fruit rots.

The second is that the cutting is not up to standard, and some potatoes have no sprouts on them.

The second is that the cutting is not up to standard, some potatoes do not have sprouts on them, and they cannot germinate after planting, and eventually they will lead to rot. Finally, the seedlings are not well preserved, and the environment is too humid, resulting in too much water and rotting during planting, and the influence of climatic conditions on late blight. High humid climate conditions with high daytime temperatures and low nighttime temperatures are the inducing factors for late blight.

When the relative humidity of the air reaches 90% and the temperature is 10 -13, the pathogen begins to invade the host and spreads the fastest.

The regulation of human resources in terms of environmental factors is limited, but everyone needs to know how to regulate them. First of all, of course, the problem of water and humidity, potatoes are not suitable for too wet soil, which will make its underground fruits absorb too much water, break the epidermis, and lead to rot The first continuous planting, a piece of land planted for a long time will lead to the accumulation of some potato pathogens, at this time, it is easy to rot when planting, and it should be cultivated on different lands. The second is that everyone's daily work after dealing with the disease is not in place.

After the rain, regardless of the soil moisture, the stickiness is too large, and at the end of the drying of loose clay soil planting potatoes, the result of which the planted potatoes rot in the ground and the seedlings are uneven, I believe that most potato farmers have been stupid enough to have such a phenomenon The above is about my sharing, I hope it can help you. I feel very happy to be able to share my experience, because I am a helpful farmer, I don't ask for anything in return for my sharing, and it is good to be able to solve your problems.

This is because potatoes are planted with high requirements for the environment and soil, most likely due to excessive rainfall, or due to excessive fertility, or improper watering.

Because potatoes still have a lot of starch and glucose, it is very easy to cause diseases or attract some pests, so when making potatoes, it is necessary to disinfect the seeds and the fields to prevent this.

Because the potatoes have some bacterial infections, they are overwatered, and there are some pests and diseases, so there is rot.

It should be watered too much, so it is very easy to happen, and in this case, the amount of water should be reduced.

It may be due to the variety, it may be due to the thin skin of the potato, it may be due to the lack of fertility of the soil, it may be due to the cultivation measures are not in place, or the weather is relatively dry.

It may be that the soil is too dry, or there is a lack of moisture, or it may be caused by a disease, or it may be a lack of nutrients, or it may be affected by the surrounding soil.

It is caused by uneven rainfall that causes potatoes to have such problems, and there are many ways to eat potatoes, and the yield is relatively high.

Potato planting should choose a deep and loose sandy loam soil, apply more farmhouse decomposed organic fertilizer as the base fertilizer, properly control nitrogen fertilizer, apply more calcium, magnesium and phosphorus fertilizer, and prohibit the application of chlorine-containing fertilizer, so as to provide a basic guarantee for improving potato yield and quality. However, there will be individual fruit cracks at harvest time, resulting in a decrease in the quality of the appearance. However, this cracking phenomenon still occurs from time to time in potato cultivation.

<> let's talk about the causes of potato cracking. First, there is the issue of potato varieties. Some early-maturing varieties have bulging tubers and rapid epidermis, and cracks appear on the surface of the tubers.

Some late-maturing varieties are planted too early, and mulching can also crack the tubers. There are also the effects of soil and fertility. If it is sandy, the stone content is high, the sand and gravel are large, and cracks will form when it expands.

The amount of organic fertilizer is insufficient, the amount of chemical fertilizer is uneven, and cracks will appear. If the amount of nitrogen and potassium fertilizer is too large, the tuber will expand too quickly, which will also cause the tuber to form cracks.

The risk safety factor for long-term food ingestion used to screen and assess synthetic chemical pesticides is five times higher than the international general requirement. A small number of farmers do not see insects, do not use medical products, focus on prevention, gradually reduce the natural enemies of plague, damage the ecological environment, pests and diseases increase year by year, enhance plague resistance, farmers blindly mix a large number of pesticides, pesticide residues in agricultural products exceed the standard, agricultural products into the human body, resulting in long-term accumulation of risks.

During the growth phase, potato starch overflows into the epidermis, causing pimples or ruptured ulcers due to drought, failure to irrigate and top dressing in a timely manner, or prolonged high temperatures and excessively humid conditions.

Insufficient application of organic fertilizer in the soil will also lead to uneven fertility, inconsistent potato expansion rate, excessive fertilization, especially too much potassium and nitrogen fertilizer added in the later stage of potato growth, potato absorption is too strong, and the root expansion is too fast, cracking will definitely occur. It is important to understand the causes of potato cracking in order to effectively prevent it. At first glance, it is believed that the cracking of the potato during the expansion period is caused by the rapid growth of the potato and the pressure of external forces.

Through communication with the family, it was learned that the potato has cracking during the expansion period, which may be affected by the planting environment, soil climate, potato varieties, cultivation methods, etc.

Because the requirements of the potato for the growth environment are very high, if the potato cracking is not prevented, it will affect the normal growth of the potato, and it will also affect the quality of the potato, and it will also affect the production of the potato, if the situation is very serious, it will also make the potato grow very small, so it is necessary to prevent the situation of potato cracking.
