What are the effects of growing potatoes if the soil is too wet?

Potatoes need water to grow, and if potatoes lack water, the tubers will be too small, resulting in slow potato growth.

However, if the potatoes are watered too much, it will also cause the potatoes to rot their roots, which may lead to the death of the potatoes.

It's best to keep the soil moist and not overwatered.

Wet soil can cause seeds to rot. Potatoes are most suitable for soils with deep topsoil, loose structure, good drainage and air permeability, and rich in organic matter, such as paddy soil (loam) and sandy loam soil in Pingchuan, Hanzhong. The clay weight of the soil affects the root development and tuber expansion, making the tuber deformed, the bud eye protruding, and the potato skin rough.

Potatoes are suitable for growing in slightly acidic soils, and potatoes are susceptible to scabs in alkaline soils.

First, it may cause root rot. Or even die. The second is that soil condition affects nutrient uptake. Potatoes will not grow sufficiently. Third, it may be to serve potatoes that don't come out often. Causing a drop in production.

Hello boss, 1Temperature potato growth requires mild, cooler climatic conditions, the ideal temperature is 13-18 degrees Celsius, and potatoes begin to grow when the soil temperature reaches 7 degrees Celsius. Extremely cold and extremely hot temperature conditions can affect the growth of potatoes, and too low temperature can easily cause small tubers and slow growth.

Too high a temperature is not easy to sit on potatoes, and it is easy to produce pests and diseases. In addition, the climatic conditions with relatively low night temperatures are conducive to potato growth and potato sitting. 2.

Frosted potatoes are very sensitive to late frosts, which can lead to the risk of slower growth and lower yields. 0 degrees Celsius will cause frost damage to potatoes and die. -2 degrees Celsius can cause frostbite to potato tubers.

3.Mild relative humidity is an important condition for potato growth. After germination, if the humidity is too high, it will also cause damage to the potato, and the air humidity is too high to produce mold.

4.Soil potatoes are a relatively low-soil crop and can be grown except in compacted and gravelly soils. Although potatoes are better drought tolerant than other crops, well-watered soil is good for potato growth because dry conditions can cause tubers to grow (chang), which can increase the number of potatoes, but they are smaller.

However, if the soil moisture is too high, it will also cause the potato tuber to have a high moisture content, low starch content, difficult to store, and cause poor taste. The ideal type of soil is a light or semi-light, silica clay, humus-rich soil with a deep layer. The pH value of the soil should be appropriate.

Potato is a crop with strong resistance to salt damage. 5 Light exposure directly affects the photoperiod and induces tubers. The short photoperiod is conducive to the setting potato, and the long photoperiod is conducive to the growth of plants, and the length of light directly affects the final yield of potato.

Bright light not only affects photosynthesis, but also flowering and tubers. These are the basics for growing potatoes, and if you feel your area is suitable for growing potatoes, you should consult with a specialist. I wish you a good harvest for all potato growers.

As a common cash crop, potatoes are widely loved by farmers. It is also a frequent guest at people's dinner tables. If you want to grow potatoes, use soil that is suitable for growing potatoes. So today, let's learn about the soil requirements for the growth of potatoes?

1.Loam, sandy loam.

Loam, sandy loam soil is more suitable for growing potatoes! Growing potatoes requires a deep soil layer and a high content of organic matter. The most suitable soils for growing potatoes are loam or sandy loam soils with high organic matter content, deep soil layers, loose and breathable soil slopes, and sufficient moisture.

Loam or sandy loam soils have good drainage and air permeability, making them suitable for growing potatoes.

2.Sand. Growing potatoes requires a deep layer of soil, and sandy soils with a high organic matter content are best.

Soft and fertile sandy soil to strengthen pest control. Potatoes are suitable for growing on sandy ground. The potatoes grown in the sand are large and delicious.

Potato tubers grow in the soil, and loose soil not only facilitates potato respiration in the soil.

3.Although the most suitable soils for growing potatoes are loam or sandy loam soils with high organic matter content, deep soil layers, loose and breathable soil slopes, and plenty of moisture. What happens if you grow in soil that is not suitable for potato growth?

1) Moist soil.

Growing potatoes in moist soil will rot the seeds. Soil viscosity affects root development and tuber expansion, resulting in tuber deformity, protruding bud eyes, and rough potato skin. The moist and sticky soil increases the resistance to the growth of potatoes.

2) Alkaline soils.

Potatoes are suitable for growing in slightly acidic soils, and are prone to scabbing in alkaline soils, which reduces the yield sharply and reduces the income of farmers.

Although potatoes can have irregular shapes due to the stickiness and hardening of the soil, what can be done to alleviate this by paying attention to tillage, drainage, dryness and wetness, and bonding with the soil? We can get good yields in this soil, colonization and soil cultivation.

The requirements for the soil to grow potatoes are very high, the soil must be acidic and alkaline soil, the soil air permeability must be very good, the nutrition must keep up, and it must be watered and fertilized regularly. When planting potatoes, you should also keep a certain distance so that the potatoes will grow particularly well. If this condition is not met, the potatoes will grow very small, and the yield of potatoes will not keep up.

The requirement for soil is to choose sandy soil as much as possible, and then it should also be watered and fertilized in time, pay attention to the fertility of the soil, strengthen the management of water and fertilizer, and pay attention to the acidity and alkalinity of the soil. If these requirements are not met, it is likely to affect the growth and development of the potatoes, and there may be problems with yields, or there is a high risk of rotting.

Potatoes are suitable for planting in loam, sandy loam, sandy soil, which can meet the needs of growth, if this requirement is not met, the potatoes will be very small, which will also affect the appearance and taste.

The soil is moist, the soil should be well drained, the soil has thickness, the sandy soil is prepared, and the soil has nutrients. The growth of potatoes is not very good, and the yield is not high.

Hello, 1Potato in the seedling stage, the seedlings are small, the air temperature is low, so the water demand is relatively small, the water demand accounts for about 15% of the whole growth period, and the normal situation does not need irrigation;

2.The water demand of potatoes in the tuber formation stage is the period of vigorous growth in the upper part of the land, and the air temperature is also rising, so that the water demand of potatoes will continue to increase during this period, and the amount of water demand of potatoes at this stage accounts for more than 25% of the whole growth period.

3.In the tuber growth stage, the growth and development rate of the upper plant and the lower tuber part of the soil will continue to accelerate, so that the water demand of potato will continue to increase during this period, and the water requirement of potato accounts for 50% of the whole growth period, which is the period with the largest water demand in the whole growth period of potato.

4.Potato starch accumulation period, in which the water requirement of potatoes is smaller, because this stage is the period when potatoes lock water and precipitate starch; Excessive water can easily cause potato rot or reduce storage time, and the water consumption of potatoes during this period accounts for about 10% of the whole growth period.

What fertilizer to use for potato fertilization should be carried out according to the growth stage. In the early stage of planting, it is necessary to apply enough base fertilizer to the plot, just use farmhouse fertilizer to improve soil fertility, so that the growth will be more vigorous in the later stage, or use the microbial agent to improve soil activity and permeability. Top dressing should be applied with 4 kg of urea fertilizer per mu after the emergence of seedlings.

After flowering, foliar fertilizer should be applied, and 3000 times of potassium dihydrogen phosphate + brassinolide can be used to make a solution of sea meal, once a week, three times in a row. In the later stage of growth, potassium fertilizer should be supplemented, and the yield of scientific topdressing will be higher.

The soil moisture is good when planting. Potatoes like hypertrophied and loose soil layers, which is beneficial to the expansion of potato pieces, and it is necessary to do the best of mechanical professional ability to deep plough up and down 25 cm, rake flat, and cover firmly. Because its growth period is short, the fertilizer period is centralized, so the fertilizer is dominated by base fertilizer, and high-quality farmhouse fertilizer is applied 1 mu 3 5 square meters before ploughing, and the organic fertilizer is applied in the furrow when planting.

Precautions for planting potatoes

Before planting potatoes, you should choose high-quality potatoes. When choosing potatoes, you should follow the "one out of a hundred" criterion, and you should choose the size of the potatoes that are smooth in shape, have no damaged skin, and are of high quality. If the peel of the selected potatoes is damaged and the appearance is irregular, planting potatoes is easy to cause a variety of pests and diseases, which is not conducive to the germination of potatoes.

The selected potatoes are cut into small pieces and germinated by hand, and the shaping and sterilization of the container closure is also remembered to prevent the potatoes from being infected by the virus.

Planting practices

Although potatoes are a very strong crop and are not susceptible to external environmental hazards, we should also choose the best planting time according to the growth habits of potatoes. Potatoes are cold-tolerant, can grow in a low temperature environment, April is the most suitable time for potato growth, different regions, it needs to choose the right planting time according to the local temperature.

Production standards

Growing potatoes is an easy task. Everybody it needs to put it in the soil and grow it. We only need to manipulate water, soil, fertilizer and other factors to improve the yield of potatoes, potatoes need a lot of water in the growth, soil moisture should be guaranteed at 50-60%, which is beneficial to promote the growth of potatoes.

In the summer, farmers fill the soil with water in time to prevent the soil from being over-dry, affecting the growth of potatoes.

Generally, when the leaves gradually turn yellow, it means that the potatoes are ripe. One month before the potato harvest, everyone needs to stop all manpower management, such as watering, fertilizing, etc. When harvesting potatoes, the speed of obtaining should be accelerated to prevent the potatoes from changing color due to sun exposure and harming the phase difference of the potatoes.

This is how potatoes are grown. If you just grow potatoes this way, you can harvest more and more potatoes.

Different soybean growth periods have different water requirements. The water in the seed potatoes can grow normally. If the soil is too dry or the soil is not good, the water in the seed potatoes is lost, or even the seed potatoes shrink completely, and they will germinate.

Budding stage. Not much moisture. At this time, the leaf area is small, the evaporation of water is less, and the water is too much, which is not conducive to the downward stretching of the roots.

In the first half of the examination, the soil remained moderately dry, and in the second half of the examination, the net photosynthetic yield was 11% to 16%, compared with the long-term drought, the net photosynthetic yield was 46% to 50%.

As one of the keys to the greatest need for water during tuber formation, the northern arid region is from late June to early July, and the rainy season is late in most years, and the water in this period plays the role of critical water. When watering in a dry year, 30% to 40%, starch content, photosynthetic tax of 20%, photosynthetic productivity of 3%, nutrient use efficiency. At the same time, it promotes nutrient absorption and operation.

The upper part of the ground is in the holy fire stage during the tuber growth period, when the growth of stems and leaves reaches the peak, the growth of sweet potato tubers is the largest, and the water requirement reaches the highest peak. Insufficient water affects tuber formation, affects the softening of parenchyma cells in the epidermis of the tuber, and aging of sweet potatoes. With sufficient water, the tuber will resume its growth, and the second or upper part of the tuber will be plucked to form a deformed sweet potato.

Only by providing sufficient water can photosynthesis flourish, which is conducive to nutrient absorption and transfer, so as to obtain high yields. Only by providing enough water can photosynthesis flourish, helping nutrients to absorb and transfer, resulting in high yields.

The starch accumulator does not require much water this time, the soil moisture is too much or the water has accumulated for more than 24 hours, and the stem surface is rotten. The tubers that last more than 30 hours rot profusely, and after 42 hours they are almost completely rotten. Therefore, lowland planting should pay attention to the drainage and high tillage in the current period.

Potatoes need cold climatic conditions to grow and develop. Germination period: 10 cm ground temperature 7 8, young shoots can grow, 10 12, young shoots thrive.

Sowing too early, the soil temperature is too low, the bud growth is inhibited, purple tubers (Mengsheng potatoes) appear, and the germination rate is greatly reduced.

Potatoes do not have high requirements for moisture in the soil, as long as there is a little bit of moisture, potatoes can survive, and potatoes are a relatively tenacious agricultural animal.

The requirements are relatively high, because the soil requirements are relatively high, that is, the water retention capacity needs to be relatively strong, so that it can grow better.

The requirements are still relatively high, generally to choose some more fertile and soft soil, if the soil is not good, the land will also cause a reduction in yield.

Something went wrong in the planting process. Don't keep your own seeds, buy new potato seeds. Do not replant.

The unscientific process of potato planting will lead to the deterioration of the potato growth environment and the production of various pests and diseases. The specific analysis of which step is wrong, and the right medicine can completely solve the phenomenon of potato degradation.

Potatoes are a silver-tolerant early drought crop that can survive in extremely arid environments. However, potatoes need a lot of water to grow normally, so the soil should be watered thoroughly during the planting process, but not irrigated with large water, otherwise the potato roots will be soaked and rotten, resulting in the inability of potatoes to grow. Potatoes also need a lot of fertilizer during the growth process, and the amount of fertilizer should be controlled to avoid root burning.

Potatoes are also a crop that prefers a cool environment, and if the temperature is too high, the resistance of potato plants to fighting against fire will be weakened, and a variety of viruses will breed. Potatoes are infected by viruses, and can not actively remove the virus in the body, the virus accumulates in the body of potatoes for a long time, affecting the normal growth of potato plants, and in severe cases, accelerating the degradation of potatoes. There are more than 30 viruses that cause potato degradation, but there are few ways to address them.

Therefore, during the planting process, it is necessary to cool the potato plants in time.

Potatoes can also be severely degraded if they are grown with their own seeds. Because after potatoes are planted, the nutrients inside the seeds will decrease, and the ability to resist viruses will also be weakened, so buying new seeds will not have this problem. If you have to keep your own varieties, you can only plant them for three years, and you must change them after three years.

And when choosing varieties for the first time, it is necessary to choose high quality, so as to reduce the phenomenon of potato degradation and yield reduction.

Potatoes should not be planted in heavy crops, and the proximity of potatoes to the soil during the growth process will produce various viruses that are harmful to potatoes, and the nutrients in the soil will also be insufficient. If it is planted again, it will affect the quality of the next crop of potatoes. It is recommended to rotate crop planting, which can reduce losses.

If you have to plant again, it is recommended to disinfect the soil and leave it for a period of time before planting.
