What is the best soil for growing potatoes? What should I pay attention to when planting?

The potato is an annual plant that produces a lot and is very adaptable. In the countryside, whether it is potato growers or farmers, it is planted sporadically, and those who know how to plant and those who do not know how to plant are carried out every year. Potato planting, in fact, is not very difficult, there is no esoteric university ask, potato production to increase, in addition to the selection of high-quality species, but also must choose the soil natural environment suitable for its growth.

Sandy loam. The definition of sandy loam is not pure sandy, it is a kind of soil with sand belt clay that does not agglomerate, does not harden, loose, breathable, and has strong permeability, <>

This kind of soil can stabilize the soil and retain water, and the soil pH value is generally neutral, especially suitable for potato growth, this natural environment potato disease is rare. It is the soil that can be used for potato cultivation, but it is not the most ideal soil. Clayey loam.

This kind of soil potato can also grow, but it is more serious in agglomeration, easy to agglomerate, poor air permeability, and easy to waterlog, causing potato disease to stagnate and rot. Because it is easy to agglomerate, it is directly related to the growth of potato rhizomes, and the general growth lump is not large, and the production volume decreases with it, and the production volume is low.

Therefore, this type of soil is very unsuitable for potato cultivation. Potato is a sun-loving food crop, the whole growth cycle time (from planting gradually, including the dormant state before budding) is generally about 3-4 months (early maturing varieties are about 3 months, late maturing varieties are about 4 months), during the growth period, the light time is long, the light intensity is large, which is beneficial to the plant photosynthesis of potato plants, and promotes long-leaf stems, erect stems and pengda.

Of course, although the growth of potatoes must be more sunlight, but potatoes are not heat-resistant, but prefer damp and cold climate, so we usually see outdoor planting potatoes in autumn, spring and winter, like now is winter, after the harvest idle farmland everyone likes to use to plant potatoes. The early long-leaf stems of potatoes must have more nutrients, and the middle and late rhizomes need more nutrients to be able to grow up, and the chemical fertilizers applied by everyone should be adsorbed and used by potato plants, which is inevitably watery, but potatoes are more drought-tolerant, generally speaking, of course, precipitation, is not a particularly long-term drought, and there is no need to intentionally water.

The most suitable soils for growing potatoes are sandy soils and light sandy loam soils with deep soils, loose soils, good aeration, and moderate water retention. When planting, it should be noted that the planting should be sown early in a timely manner, the planting should be deep and the moisture should be enough fertilizer, the planting should be germinated and cut, and the planting and sowing depth should be very important.

You can choose more fertile land, and you must pay attention to watering, fertilization, and variety selection when planting.

Potatoes prefer acidic soils. Potatoes can be grown on any soil with a pH, and the most suitable soil pH is. When the soil pH value, the plants showed premature senescence and reduced yield.

From the perspective of agricultural production, a four-year crop rotation is ideal in the main potato producing areas, but in practice, it is very rare for many commercial potatoes and seed potatoes to achieve a three-year crop rotation, and farmers must accept yield losses due to soil-borne diseases.

Disease & Management. Potatoes need soft, breathable soil, water and fertilizer to grow, drought can irrigate floods and drain floods, and fertile semi-clay and semi-sandy loam soils. Potatoes are highly reproductive, sprouting and growing as soon as the tubers with eyes are cut into small pieces, and in the past, rapid reproduction was achieved through this method.

Now, with the development of technological productivity, this method of rapid propagation has been replaced by the "detoxified potato". Detoxified potatoes are virus-free** potatoes grown in tissue culture through biotechnology.

This variety has no pathogenic source, fast growth, high yield, and is widely used. Potato diseases mainly include ring rot, mosaic disease, scab, etc., and 99% oxazole, 70% thiobillus, 75% chlorothalonil, 70% methofen and other contact adsorption antibacterial agents, seed blocks or field spraying can be used to prevent and control potato diseases. Potato is an annual herbaceous plant with a large yield and wide adaptability.

In rural areas, whether it is a large potato grower or a farmer who grows sporadically, it is an annual thing that knows how to plant and does not know how to plant.

Potato cultivation, in fact, is very simple, without profound knowledge, in order to produce potatoes, in addition to selecting excellent varieties, it is also necessary to choose a suitable soil environment for its growth. Potato is a crop that grows on the ground, the soil is equivalent to its "home", and the environment of "home" will affect the growth quality of potatoes, the growth of potatoes is mainly long stems and leaves, and the later stage is underground tubers, and the tubers are expanded, what kind of soil is suitable for growing potatoes?

Soil pH is neutral, acidic, soil layer is subsoiled, soil drainage is strong, fertility is maintained, which is related to the growth characteristics of the potato itself, the specific analysis is as follows: Potato is a very bright light crop, the growth cycle (starting from the mother, including inactive before emergence) is generally 3 4 months (about 3 months for early-maturing varieties, about 4 months for late-maturing varieties), during the growth period, the light time is long, the light intensity is large, which is conducive to potato plants, promotes photosynthesis of long stems and leaves, and the growth and development of each piece. Of course, although potatoes need more light to grow, potatoes are not tolerant to high temperatures, but prefer cold and cool climates, so we usually see potatoes grown in the open air generally in autumn, winter, and spring, just like it is winter, and people like to pick potatoes in the idle fields after the autumn harvest.

Loose soils and soil with good air permeability are more suitable for growing potatoes. It is necessary to pay attention to the depth of planting, but also to the method of sowing, but also to the pH of the soil, but also to the frequency of watering, but also to pay attention to the pH value of the soil.

The soil is fertile, loose, permeable and drainable, and the better soil is more suitable for growing potatoes; When planting, we must pay attention to the relevant field management, proper fertilization and watering, spraying some nutrient solution, and proper light.

Softer soil, more comfortable soil, and better air permeability are more suitable for planting. It is necessary to pay attention to the spacing of planting, the depth of planting, the planting mode, the planting technique, and the planting skills.

1. Soil: Slightly acidic sandy loam soil with deep tillage layer, good drainage and irrigation performance, and pH value is suitable for planting potatoes.

2. Nutrition: Potassium is the most important factor in fertilizer, followed by nitrogen, and finally phosphorus.

3. Temperature: Potatoes like a cold environment, the appropriate temperature during growth and development is 17-21, the growth temperature of primary seedlings is 13-18, and the appropriate temperature for tuber formation is 20.

4. Pre-dressing water: the water holding capacity in the field should be kept at 65% at the seedling stage, 75-80% at the tuber formation stage, and 75-80% at the tuber expansion stage.

Potatoes are a very common crop in our country, like many children can often eat potatoes at school when they are young, and the demand for potatoes in various provinces is still relatively large. Potatoes are not so delicate plants, and it is not about what kind of soil to choose when planting, but the soil should at least be looser, have good air permeability, and have enough fertility, so that the potatoes can grow big and good. <>

In fact, no matter what kind of crops are grown, the soil must be fertile, and the same is true for potatoes. Potatoes need very fertile soil when growing, the ratio of nitrogen, phosphorus, and potassium in the soil should also be appropriate, and the soil should contain a variety of organic matter, such as the kind of soil is very fertile, and the soil layer is very deep, so that potatoes can grow better. The roots of potatoes are actually relatively shallow, and in the process of growing, if there is too much water in the soil, it will cause the roots of potatoes to rot, especially in rainy weather, too much water in the soil is not a good thing for potatoes.

Therefore, when planting potatoes, another requirement is to keep the soil loose and well-drained, and there should be no stagnant water. In this very loose, breathable and well-drained soil, the growth of potatoes will not be hindered, and the potatoes will grow with a rounder and smoother skin. Potatoes also have requirements for the acidity and alkalinity of the soil, which is more suitable for planting in acidic soil, if it is alkaline soil, potatoes are very prone to scabs, and the yield will be low.

However, the acidity of the soil should not be too acidic, as long as it is maintained within the appropriate range, and the approximate value is between. <>

Potatoes prefer light in the process of growth, if the light is insufficient, the potato will expand more slowly, and the yield will be reduced, so the sunshine time has different effects in different periods of potato growth. Potatoes are very intolerant to high temperatures, the best growth temperature of potatoes in the ground is about 16 18 degrees, and the temperature of the above leaves is about 15 25 degrees, so you should also control the temperature when planting potatoes, otherwise the potatoes will grow more slowly and may stop growing.

Growing potatoes is actually a relatively simple thing, first of all, we have to choose the right soil to plant, because potatoes grow in the soil, so the soil becomes crucial, which will directly affect the growth and yield of potatoes.

If you want to grow this plant well, you must first understand what the growth habit is, potatoes are a plant that likes light very much, and potatoes are also more suitable for cold climates, and are not very resistant to high temperatures.

In the choice of soil, we must choose a deeper and loose and breathable one, and we must pay attention to the drainage function of the soil, it is very good to plant potatoes in some sandy land, because in the process of growth, potatoes will continue to increase, and the loose soil is the most delicious at this time.

Even in sandy areas, you don't have to worry, because potatoes are a relatively drought-tolerant plant, and they generally don't need to be watered in the later stage, as long as the growing place is not very arid.

Acidic soil places have high temperatures and more rainfall, which is very suitable for growing potatoes, such as some tropical areas, Sichuan, Yunnan, Hainan, etc., where there will be carbonic acid in these rains, so the land will be acidic.

Usually acidic soils are mainly dark brown in appearance, even if the field is dry, it will not form plates, and after the Xigou water, the whole will suddenly become softer, and the surface will not show obvious water accumulation.

In fact, in these agricultural plantings, many plants are more suitable for acidic soil, which is loose and breathable, but this soil is also relatively lacking in fertilizer and calcium, and potatoes are a plant that likes fertilizer very much, so it must be topdressed in time, and it is worth noting that the same land is not suitable for planting the same plant every year.

The soil is fertile, and the light loam soil with good permeability is more suitable for growing potatoes; Loam, sandy loam, sandstone soil, all are recommended.

Sandy loam soil, high organic matter content, slightly alkaline black loam soil is suitable for potato planting.

Generally, potatoes are planted on sunny slopes, but in sand fields, potatoes will be sweeter and have a very good taste.

Potatoes are grown in soil and need fertile soil to absorb enough nutrients. Potatoes need loose and breathable soil conditions and a cool environment, and the temperature should not be too high and suitable, otherwise it will affect growth. Growing at a temperature of 15-18 degrees, potatoes are better.

Potatoes need a lot of water during the growth process, and the water content is relatively high. It is best to keep the soil moist and have a moisture content of around 60%. Especially in the seedling stage of potatoes, there is a great demand for water, so it is necessary to ensure the best water.

After harvesting, potatoes cannot germinate for a long time in an environment suitable for germination. A lot of people are anxious about this. In fact, this is a physiological natural dormancy of potatoes, which is an adaptation to an unfavorable environment.

Depending on the variety, the dormancy period varies from one month to three months.

When the temperature is too low, potatoes can sleep for a long time, so it is important to find an environment that is suitable for potatoes to grow. The flowering period of potatoes requires a lot of water and fertilizer, which is the flowering period of potatoes. The fertilizer should be high-quality organic fertilizer, adhere to the combination of organic fertilizer and ternary fertilizer, can loosen the potato layer, is conducive to potato root absorption.

Sowing should be spaced at a certain interval because potatoes need enough space to grow underground, otherwise the potatoes will grow very small and the yield will be low. Secondly, fertilizer is applied once when planting, and the fertilizer is mainly farmhouse fertilizer, and the fertilizer cannot directly touch the seed block, otherwise the potatoes will be burned to death.

Potatoes should be inspected when they bloom, because at this time the potatoes will have some diseases that will seriously affect the quality and yield of potatoes, so be very careful. The growth of potatoes begins with the germination of buds on tubers. Only when the tuber breaks dormancy can the buds and seedlings grow significantly.

The germination stage is from germination to emergence, and the growth of the first section of the main stem is carried out. The growth center of the germination stage is the elongation of buds, rooting and the formation of stolons. Nutrients and water are mainly supplied by seed potatoes, which are supplied in the order of stems, leaves, and roots.

The environmental conditions required for the growth and germination of potato seeds limit their growth rate and quality. After the potato is harvested, it is put into a suitable environment for germination, and it cannot germinate for a long time, which belongs to physiological natural dormancy, which is an adaptation to the unfavorable environment. When the pole growth at the tip of the stolons stops and the tubers begin to expand, tuber dormancy begins.

The length of dormancy time is related to the storability of the tuber, whether the seedlings can emerge in time after sowing, and thus the yield.
