Is a potato the root or stem of a plant, and what root or stem does a potato eat

Stem.

Potato is the stem of the plant, belongs to the tuber, grows in the soil layer, in the initial base will grow roots, and then grow out of the stolon, and so on in the later stage the end of the stolons will gradually expand, so as to form a potato, to provide sufficient scattered light for the plant when breeding, to promote the formation of tubers.

1. The stem of the plant

Potatoes belong to the tuber stems of plants, which grow in the soil, and in the early stage of potato growth, roots will grow at the base of the soil, gradually forming stolons, and in the later stage, the end of the stolons will expand to form tubers, that is, potatoes.

2. Provide light

Potatoes have a high demand for light, and when the plants grow leaves, they should be provided with full sunlight to allow the leaves to fully photosynthesize, thereby promoting the formation of tubers and increasing the yield and starch content of potatoes.

3. Apply fertilizer

Potato in the process of growth, need dozens of nutrients, during the growth of the plant, to apply potassium fertilizer-based, nitrogen fertilizer and phosphate fertilizer supplemented by compound fertilizer, to promote the growth of potatoes, pay attention to the stolons in the stolon, to reduce the amount of phosphorus fertilizer, in order to prevent affecting the quality of potatoes.

The edible part of the potato is the stem of the plant, and the potato grows in the soil, like a root, but it is actually a stem, but it is called a tuber. The stem is characterized by internodes, terminal buds, and lateral buds. The young stems should be green.

Potatoes adapted to a long underground life, lost their green color, deformed and turned into tubers.

Potato tubers contain a lot of starch, can provide rich calories for the human body, and rich in protein, amino acids and a variety of vitamins, minerals, especially its vitamin content is the most complete of all food crops, in Europe and the United States, especially in North America, potatoes have long become the second staple food.

Roots, stems, and leaves grow separately in the soil.

Under certain conditions, the potato plant grows and develops under the close coordination of roots, stems and leaves. From the moment the seedlings emerge, their green stems and leaves begin to use photosynthesis to produce nutrients, and well-developed roots absorb enough water and inorganic elements from the soil for the growth and utilization of all parts of the plant.

With the distribution of nutrients in the plant and the growth and development of roots, stems and leaves, a complete plant growth system is formed until flowering reaches the maximum flourishing of the plant.

The roots and tubers of potatoes grow in the soil, and the roots mainly play the role of absorbing water and nutrients to provide growth, and the tubers mainly store nutrients and reproduce.

The main stem and leaves grow on the ground, and the stem plays the role of transporting water and nutrients, and also plays the role of supporting the leaves and branches. Leaves play a role in photosynthesis, the production of nutrients and gas exchange.

A potato is the stem of a plant.

Potatoes can be planted in March-April in spring and September-October in autumn, and winter is best planted around December-January each year. Potatoes are tubers that grow in the ground, roots will grow at the base in the early stage, and stolons will also grow, and the end of the stolons will gradually expand in the later stage, so as to form potatoes, and the plants should be provided with sufficient scattered light to promote the formation of tubers.

The seed potatoes of potatoes can only germinate and grow when the soil surface temperature reaches 5-8, and the most suitable temperature for their growth is about 15-20 ridges of Sakura. China's geographical area is vast, the climate of different regions has certain differences, so the sowing time is also different, only the temperature and Qingqi meet the growth needs to sow and plant potatoes, but it is best to sow early in time.

Precautions for growing potatoes

Before planting potatoes, apply well-rotted organic fertilizer to the soil as a base fertilizer to increase the fertility of the soil. Because potatoes are fertilizer-loving plants, during the growth of the plant, it is necessary to apply well-rotted organic fertilizer to promote the growth of potato tubers, and during the expansion period of potato tubers, liquid fertilizer should be sprayed on its foliar surface, and urea should be applied every 5-7 days.

In the process of potato growth, it is necessary not to water the plant before it buds, so as to avoid the phenomenon of overgrowth of the ground part of the potato; After the potatoes have budded, they should be watered to promote the growth of underground stems. Ten days before harvesting, potatoes should not be watered and fertilized so that they do not rot.

Potatoes are stems that belong to plants.

All stems have knots, whether they are above-ground stems, underground stems, stolons, or bulbs......, on which sections can be found. But some of the verses are obvious, and some are not so clear. And there are no knots at the root.

Sometimes you can see a knot-like shape on the roots, for example, there are also holes on the roots of radishes, which are like holes on potato tubers, but in fact, there is an essential difference between the two, the former is the traces of the lateral roots on the fleshy straight roots of the radish after falling off, while the latter is a node with long scaly leaves.

The most water and fertilizer needs during the growth period of potatoes is the flowering period, which is also the season of rising temperature and increased rainfall, and it is also the stage when organic fertilizer gradually matures and decomposes and releases nutrients. At this time, the transformation benefits of organic fertilizer and inorganic fertilizer in basal fertilizer continued to expand, which met the nutrient demand during potato growth and promoted plant growth and development.

How potatoes are grown

Seed selection treatment. 1) Choose excellent potato varieties with high yield, disease resistance, excellent quality and good taste suitable for local climatic characteristics, especially detoxified potatoes. The fresh food varieties for export should have a good potato shape, shallow bud eyes, and smooth potato skin.

2) 15 days before sowing, select tubers with the characteristics of this variety, fresh skin color, no cracks, and no disease spots as seed potatoes, and then dry and cut seeds. When cutting the buds, each piece should ensure that there are 1-2 bud eyes, and then disinfect the beams with carbendazim. The cut potato pieces are mixed with plant ash, which not only has the effect of seed fertilizer, but also has the effect of disease prevention.

A potato is the stem of a plant.

It is a tuber stem that grows in the soil layer. In the early stage, the base will grow roots, and then grow stolons, and in the later stage, the end of the stolons will gradually expand, thus forming potatoes, and the plants should be cultivated to provide sufficient scattered light to promote the formation of tubers.

When sowing multiplying potatoes, it is necessary to carry out when the temperature in the soil is continuously higher than 10 degrees. It can increase the germination rate of the plant, and apply well-rotted organic fertilizer to the soil as a base fertilizer, and then bury the potato seeds in the soil, wait for a week or two, and the potatoes will germinate.

Growth Cycle:

1. Mature tubers can be sown as seed potatoes after a period of dormancy, that is, the dormant stage.

2. After sowing, rely on its own nutrition to take root and sprout and grow seedlings, that is, the autotrophic stage.

3. After the emergence of seedlings, organic matter is produced through photosynthesis, and the root system is used to absorb water and inorganic elements to form a complete plant growth system until flowering reaches the maximum flourishing of the plant, that is, the heterotrophic stage.

4. After flowering, the aboveground part stops growing, and the tuber expands rapidly, accumulating nutrients to maturity, that is, the tuber formation stage.
