Why can soil affect the commerciality of potatoes? What kind of soil is suitable for growing potatoe

Sandy loam soil is more suitable for potato growth and development than gum soil, sandy loam soil is soft, more suitable for potato than gum soil, but potato tubers for growth and development of gum soil are small but more flavorful; Then there is the soil organic matter, whether it is sandy loam soil or cement soil, the fertilizer efficiency is weak and can not produce better potatoes, especially under the premise of insufficient water supply. For the commercialization of potatoes, the soil layer may only harm the size of the potato, but the size of the potato does not seem to be harmful to sales. The sandy soil layer is best suited for potato growth and development because it is rich, breathable and <>

It is beneficial for the growth and development of underground stems. The spring warms up quickly, the potato nuggets sprout quickly, and the buds are full, which is conducive to early sowing and the budding of rhizomes, and promotes the growth and development of plants; The sand has strong drainage pipes, which can promote potato ripening and reduce the growth period according to the provision of reduced moisture; Sand is easy to cultivate, easy to obtain, and saves labor; Sandy loam soil is also beneficial to the growth and development of potato rhizomes, strong rhizomes, can fully digest and absorb the nutrients and water of the soil layer to provide the upper part of the ground leaves, so that the upper branches of the ground are lush, and give strong material conditions for the production and expansion of rhizomes. Potatoes grown in sandy soil are clean and tidy, with a smooth skin and <>

The potato shape is normal, the starch content is high, the variety is good, and it is easy to obtain. The rhizomes of potatoes are generally distributed in the shallow part of the soil layer and are susceptible to external environmental damage. The best soils for growing potatoes are soils or sandy loams with high organic matter content, thick soil layers, loose and permeable steep slopes, and plenty of moisture.

However, the adaptability of potatoes is relatively extensive, and some practical cultivation methods and countermeasures can be used to plant on other soil layers, and the yield can also be increased. Potatoes are a crop that prefers to grow in a soft, rich, permeable layer of soil, and <> when growing potatoes

Generally, it is to select a soil layer with strong organic matter content and good loose air permeability to plant, which is generally beneficial to the development of potatoes and Pengda, and the potatoes grown in this soil layer are generally very high in quality and production. The clayey soil layer has good water retention but poor air permeability, and this soil layer must be planted with high ridges for potatoes. In flat planting and small ridge planting, because the soil layer is very easy to stick, it often sprouts and changes color, the deformed potatoes are raised, and the environmental humidity rises.

However, the soil layer has strong hydroelectric power and fertilizer retention efficiency, and the amount of management methods is quite high. Therefore, the clay should be covered with a mulch film planting, and it is proposed that the film be detached to the end.

Of course, people plant potatoes are looking forward to the end can produce more than one and larger potatoes, and the potatoes that the potato plants bear are in the underground soil layer, the potatoes should continue to expand, and the soil is required to be deep, loose and breathable, and it is easy to absorb fertilizer and oxygen to grow, and can not store too much water, so as not to damage the roots and tubers, and such soil itself is also conducive to people to cultivate the potatoes, so as not to expose the ground and green without soil cover, affecting the quality. There is a certain reason that the soil pH is neutral to acidic, the soil layer is deep and loose, and the soil with strong drainage and fertilizer retention properties is suitable for growing potatoes.

If the quality of the soil is too poor, then it will affect the growth of the potatoes and affect the overall quality. It is better to choose a fertile sandy soil.

In the process of growing potatoes, it is important to choose loose and fertile soil, and choose soil with a relatively high content of organic matter and humus. This will allow the potatoes to grow better.

Potato, also known as potato, belongs to the Solanaceae family, an annual plant with stems, leaves, flowers, fruit seeds in the aboveground part, and roots, stolons and tubers in the underground part. The tuber is the edible part. The temperature requirement is between 20-25 degrees, it is not suitable for high temperature planting, and the soil needs to be covered with a layer of 5 cm of sand when planting, and the planting density of potatoes does not need to be too large, and the ditch needs to be dug to facilitate the subsequent fertilization management.

In this place, potatoes can be grown at any time of the year. For example, in our more northern regions, you can grow potatoes in February, March, July and August every year. These two places are just examples, so we need to understand the climate change in the land where we grow before planting.

After the harvest of the previous crop, the depth of the ground is turned over the ridge, the depth is required to be 15 to 20 cm, and the appropriate amount of fully rotted farmhouse fertilizer is applied in the dragon hook. When planting potatoes, it is necessary to implement crop rotation and stubble, so that the active seed potatoes are cut into pieces, and they do not need to be cut if they are small. However, it should be noted that the cut seed potatoes must prevent them from rotting, and one of the ways to do this is to get some ash on the incisions.

<> potatoes want to have high yields, then it is very important when choosing the land. You must choose a place where the soil is relatively fertile, the soil is relatively loose and the sandy soil is the best growing conditions. Secondly, when arranging the garden, try to dig the soil a little deeper, so that the soil is really finer and not piece by piece.

Fertilization, potato growth period is short, it is necessary to concentrate on applying more base fertilizer, southern Shaanxi people generally apply farmhouse dry manure, water manure in the toilet, and then put some nitrogen, phosphorus and potassium fertilizer triammonia. It is best to pinch off the flowers when they bloom. The whole growth process can be matured by watering three times, and if you see honey worms on the leaves, you should immediately spray pesticides, otherwise it will affect the yield.

In the winter, the potato seeds are placed in a warm place to promote germination, and when the spring equinox of the following year is planted, the sprouted beans are cut into several pieces, so that each small piece has at least one sprout.

That is, the environment of potatoes needs to be drier, and the soil is loose and breathable, and it must be fertile, and you can plant Jinong 958 in the south, this variety of potatoes has a relatively high demand for the environment, and the climate in the south can just match.

The ambient temperature around is relatively high, and the soil is relatively fertile, so the south is suitable for planting Zhongshu No. 2, so that the yield will be relatively high when planting, and it is suitable for the climate of the south.

The environment for potato planting must be very warm, the planting effect is very good in a season like spring, and the south is suitable for planting potatoes like No. 605, and the growing environment is very suitable.

Juvenile and juvenile potatoesThese two types of tubers have a shorter growth time on the plant, smaller tubers, soft and smooth skin, and bright skin color that is not easy to fade. The potato shape is regular, the dormancy period is long, it is more resistant to storage, and the young shoots are thick. These tubers have robust characteristics and produce strong, productive plants.

Mature potato: The growth period of the mature potato on the plant is shorter, but the tuber is larger than the young potato, the potato shape is neat, and the other characteristics are the same as the young potato, which is especially suitable for seed potatoes.

Old potatoes: They take the longest time to grow on plants, usually harvested with the imitation yellowing of stems and leaves, and the size of the tubers is all the same, and the quality of small old potatoes is worse. The shape of the potato is varied, such as round and oval varieties, the shape of the potato often becomes elongated, pointed, deformed, and cracked; The long potato shape often becomes short or round.

The skin of the old potato is rough and aging, the skin color is dull, and the skin color of the varieties with colored skin becomes lighter, especially the top fades, and the bud eyes, top, and umbilicus all change from deep to shallow, and even protruding. The dormancy period becomes shorter and the young shoots are weaker. The vitality of these tubers tends to decline.

If used as a seed potato, it will form a "declining" plant, that is, the stalk is slender and weak, premature senescence, and low yield. Therefore, old potatoes are not suitable for seed potatoes.

One acre of land, when planting, put the potatoes sparsely planted a little, about 200 to 300 catties, you can get it, the seeds are about 300 500 can also be done, sparse planting a little bit of potatoes, the yield is higher, I took back this year Ma Yukuan potatoes, half a catty 1 potato, and a small potato. We usually grow small potatoes, which are more delicious, the small ones are easy to rot and taste good when cooked, and the big ones are harder and not very tasty. I can't estimate how many kinds of vegetables are needed per acre, and the cost will be higher if there are special vegetables for sowing, but the probability of infection with viruses and bacteria is low.

Therefore, more and more people prefer to sow whole potatoes. From practical experience, the size of the whole potato is 10 20 grams is more economical.

A bamboo platform is built in the light room, and the straw soaked in warm salt water is spread, and then the potatoes are spread on the straw at an interval of 2-3cm to promote hail and remove the fiber sprouts. In this way, the germination rate of potato seed potatoes is relatively high, and the seed potatoes required for one acre of land are about 200 catties. Potato production should pay attention to reasonable dense planting, should not be too dense or too thin, can not only give full play to the production potential of individual plants, but also form a reasonable field group structure, to achieve a reasonable leaf area index, which is conducive to photosynthesis and group dry matter accumulation If the unit surface is sown with seeds, the seeds should be treated and germinated in advance, and planted in February-March or August each year.

The main requirements for the soil for potato growth are as follows:

1.Soil type: Potatoes are suitable for growing in deep, loosely structured, well-drained and aerated soils rich in organic matter. For example, slightly acidic or neutral sandy loam or loam soils.

2.Soil fertility: Potatoes need fertile soil, which should be rich in organic matter and contain the right amount of nitrogen, phosphorus, potassium and other elements.

3.Soil aeration: Soil aeration is essential for potato growth and development, as it promotes root respiration and nutrient uptake.

4.Soil pH: Potatoes are suitable for growing in slightly acidic to neutral soils with a pH value not higher.

5.Avoid heavy cropping: Potatoes should not be re-cropped or rotated with Solanaceae crops to avoid infection with pathogens.

If you want to grow potatoes, it is advisable to first check the quality of your soil according to these requirements, and if necessary, add suitable fertilizers or do soil improvement.

Potatoes have a wide range of soil adaptation, and the most suitable soil for potato growth is light loam, and the potatoes planted on this kind of soil germinate quickly, emerge neatly, and the tubers grow with smooth skin, normal potato shape, and high commodity rate. Potatoes planted on clay soil are best cultivated on high ridges, this kind of soil has poor aeration, and often causes rotten potatoes in the later stage due to poor drainage, so it is necessary to strengthen field management, timely cultivation, weeding and soil cultivation. Potatoes planted on sandy soil should be planted flat soil and sown deeply.

Potato is a crop that prefers acidic soil, potato growth is relatively normal between soil pH, but pH is the best, potato is prone to scab on alkaline soil, and the buds of tubers can not grow after sowing, and even die.
