The difference between potatoes and potatoes

A kind of food that is indispensable to every household is potato, which is what we often call potatoes. There is no difference between potatoes and potatoes. They are the same food. The yield of potatoes is very high, so the price is very low. Many families like to use them to cook. Potatoes taste very good and can be paired with many other dishes, such as stewed potatoes with green beans, fried potatoes with green peppers, etc.

Potato (Solanum tuberosum) is also known as potato, sweet potato, yam egg, etc. (See the picture on the right, I grew it myself) It belongs to the Solanaceae family, a perennial herb, but is cultivated as an annual or twice a year. The underground tubers are round, ovate, oval, etc. in shape and have eyes; the aboveground stems are triangular and hairy; the leaves are odd-pinnate, with terminal umbels and white, red or purple flowers; the seeds are flat, round and yellow, and are mostly propagated by tubers. The tubers are edible and are an important dual-purpose food and vegetable crop. Because of their rich nutrients, they are known as the "underground apple" and are one of the world's five major food crops (the five major food crops are rice, wheat, corn, sorghum, and potatoes). It is widely cultivated as a food crop in many European and American countries. This plant is native to the Peruvian Andes and coastal areas of Chile in South America. It was introduced to Europe in the early fifteenth century and then quickly spread to all parts of the world. It was introduced into my country around the middle of the sixteenth century.

Potatoes are low in calories, containing 90 calories per 100 grams, while the same amount of rice or flour contains 350 calories. The carbohydrates it contains are easily assimilated into the blood and can resist hunger without hurting the stomach.

Potatoes have high yields and are highly adaptable to the environment. China's main potato producing areas are the southwestern mountainous areas, the northwest, Inner Mongolia and the northeast. Among them, the southwestern mountainous areas have the largest sowing area, accounting for about 1/3 of the country's total area. Heilongjiang Province is the largest potato planting base in the country.

When using tubers for asexual reproduction, the seed potatoes can germinate and grow at a soil temperature of 5 to 8°C, and the optimum temperature is 15 to 20°C. The temperature suitable for the growth of plant stems and leaves and flowering is 16-22℃. The most suitable night temperature for tuber formation is 10-13℃ (soil temperature 16-18℃). When it is above 20℃, the formation will be slow. The plants will be damaged by frost if the temperature drops to -2℃ during the emergence and seedling stages.

The flowering and tuber formation period is the period with the highest water demand in the entire growth period. In case of drought, irrigating 15 to 20 tons of water per mu each time is the key technical measure to ensure high and stable potato yields.

Generally, potatoes absorb about 6.65-11.65 kg of nitrogen, 2.8-3.3 kg of phosphoric acid and 9.3-15.3 kg of potassium oxide when the yield per mu is 1330-1650 kg. Although potatoes can adapt to a variety of soils, loose and organic-rich (pH 5.5-6.0) black soil is the most ideal. The density of seedlings per mu should not be less than 4,000.
