2. Explanatory text, potatoes that write potatoes
Potato (Solanum tuberosum) is also known as potato, potato and yam egg. (See the picture on the right, I planted it myself) belongs to Solanaceae, a perennial herb, but it is cultivated once a year or twice a year. Underground tubers are round, oval, oval and have bud eyes; The aboveground stems are triangular and hairy; Odd pinnate compound leaves, terminal corymb, white, red or purple; The seeds are oblate and yellow, and are mostly propagated by tubers. Tubers are edible and are important crops for both food and vegetables. Because of their rich nutrition, they are called "underground apples" and one of the five major food crops in the world (the five major food crops refer to rice, wheat, corn, sorghum and potato). It is widely cultivated as a food crop in many countries in Europe and America. This product is native to the Andes of Peru and the coastal areas of Chile in South America. It was introduced to Europe in the early 15th century, and then spread to all parts of the world quickly. It was introduced into China in the mid-16th century.
Potato has a low calorie content, 90 calories per 100 grams, while the same amount of rice or flour reaches 350 calories. The carbohydrates it contains are easily assimilated into blood, and it can resist hunger without hurting the stomach.
Potato has high yield and strong adaptability to the environment. The main potato producing areas in China are southwest mountainous area, northwest, Inner Mongolia and northeast China. Among them, the planting area in Nanshan District of Taihai Ka, the nuclear turtle in Xiji Penalty Museum, is the largest, accounting for about 1/3 of the total area in China. Heilongjiang Province is the largest potato planting base in China.
When the tuber is used for asexual propagation, the seed potato can germinate and grow at the soil temperature of 5~8℃, and the optimum temperature is 15~20℃. The suitable temperature for the growth and flowering of plant stems and leaves is 16~22℃. The most suitable temperature for tuber formation at night is 10~ 13℃ (soil temperature 16~ 18℃), and it forms slowly when it is higher than 20℃. When the temperature drops to -2℃, it will be damaged by freezing.
The period of flowering and tuber formation is the period of maximum water demand in the whole growth period. In case of drought, irrigation per mu 15~20 tons is the key technical measure to ensure high and stable yield of potatoes.
Generally speaking, potato absorbs about 6.65 ~1/0.65 kg of nitrogen, 2.8~3.3 kg of phosphoric acid and 9.3~ 15.3 kg of potassium oxide under the condition of per mu yield1650 kg. Although potatoes can adapt to a variety of soils, black soil with loose and rich organic matter (pH5.5~6.0) is the most ideal. The density should not be less than 4000 seedlings per mu.
Experts remind: you must peel potatoes when you eat them.
Potatoes, sweet potatoes, taro and other potato foods are rich in nutrients. The contents of protein, vitamin C, vitamin B 1 and vitamin B2 are much higher than those of apples, and the contents of calcium, phosphorus, magnesium and potassium are also very high, especially the content of potassium, which can be said to rank first among vegetables. Potatoes contain a lot of high-quality cellulose, which can prevent constipation and prevent cancer. So, how to eat potatoes to eat well?
First of all, to ensure the quantity, eating potato food (potato, sweet potato, taro) every day should be about 80 grams. Secondly, the combination of meat and vegetables is good. As long as the combination is good, you can enjoy the food and achieve the goal of keeping slim. When eating potatoes, the intake of staple food should be reduced accordingly, which can be controlled according to the ratio of potatoes to staple food of 3∶ 1~4∶ 1. If you eat about 80 grams of potato food every day, it may help reduce the risk of stroke.
For many mashed potatoes and French fries in fast food, they are oxidized during processing, which destroys a lot of vitamin C and greatly reduces the nutritional components. For French fries, it is easy to increase the intake of fat, and it is difficult to judge whether the oil of French fries is fresh. In addition, repeated high-temperature heating produces polymers, such as toxic cyclic monomers, which are carcinogens, so eat as little as possible.
Nutritionists point out that eating potatoes does not need to worry about excess fat, because it only contains 0. 1% fat, which is the least among all hunger foods. Eating more potatoes every day can reduce fat intake and gradually metabolize excess fat.
However, it is worth noting that potatoes, especially potatoes, contain a toxic substance called alkaloids, which can cause poisoning, nausea, diarrhea and other reactions when ingested in large quantities. This toxic compound is usually concentrated in the potato skin, so it must be peeled when eating, especially when peeling the green skin. In addition, potatoes with buds are more toxic. When eating, you must dig out the buds and roots and soak them in clear water. Stewing and cooking should be on fire.
In addition, if pregnant women often eat potatoes with high alkaloid content, accumulation in the body may lead to fetal malformation. Of course, there are considerable individual differences among people, and not everyone will have abnormalities after eating potatoes. However, it is better for pregnant women not to eat or eat less potatoes, especially potatoes that have been stored and germinated for a long time, which is especially important for women in the early pregnancy.

I chose a few big ones, paid the money and went home.
After buying it, I walked home to the bottom of the building and didn't dare to go up. I couldn't stop blaming myself. I couldn't even buy a potato in such a big vegetable market. If the potato I bought this time was wrong, I had to run again. I finally decided to go up. My mother took the dish in my hand, looked at it and said to me, "This is the potato. You can help my mother with her work." I suddenly realized, oh, potatoes are potatoes!

6. Writing a potato-quality composition of 200 words does not have a gorgeous body, and it can't be praised by people when buried underground; Scarred skin, covered with khaki clothes. This seems to be the insipid potato in people's eyes forever! But have you ever thought about it? When apples and pears are dressed in gorgeous and conspicuous fashions, potatoes are always left out in the cold for a while. They still sit quietly in the soil like oxen, waiting for farmers to dig them up. When people loudly praise all kinds of fruits, it doesn't care about anything. Although these are all insignificant benefits, they make me deeply moved.
Aren't there many people with potato quality in life? Teachers are typical representatives of those who have made contributions to society. They stick to their posts regardless of the wind and rain. Day by day, they sweat like rain, like hardworking gardeners watering delicate seedlings, and they are like our reborn parents. In the morning, they listened to our loud reading and smiled with relief; At noon, they rushed to the canteen non-stop, ate lunch hastily, and buried themselves in revising the lesson plan; They dragged themselves home until late at night. Teacher! Regardless of fame and fortune, obscurity, selfless dedication, this is the bright spot that shines like gold on the teacher. "Cultivating talents for the country" is their firm slogan. Teacher! In order to repay your efforts, we will study hard and redouble our efforts! We are "mature", but the teacher's back is bent, and I see the shadow of potatoes from them again ...
