Hope, thank you.

The surface of the leaves is densely hairy, one lanceolate, one capitate. All of them have the effect of collecting water vapor in the air, and some varieties also have the effect of resisting pests. A pair of lobed leaves on the left and right sides of the junction between the base of the compound leaf petiole and the main stem are called the supporting leaves, which are sickle-shaped, leaflet-shaped or intermediate-shaped.

The shape of the leaves of different varieties is different, such as the shape, size, logarithm and density of the leaflets, the angle between the leaflets and the leaf axis, the amount of hairiness on the leaf surface, the degree of smoothness and wrinkles on the leaf surface, and the length of the petioles.

The surface of potato leaves is densely hairy, one lanceolate, one capitate, and the chlorophyll in potato leaves.

It is very rich, as well as other elements, lutein, carotene.

cellulose and other elements.

<> like this, the leaves of potatoes mainly produce starch through photosynthesis, and then store the excess starch in the tubers, which are potatoes.

The leaves of the potatoes are the ones that grow bigger when they photosynthesize.

Potato leaves are similar to tree leaves, and he provides nutrients to potatoes.

What is the shape of the leaves of the potato Seeds with orange-yellow or yellow flowers are cultivated for ornamental. usually not more than 60 cm (2 ft); The leaves are multi-basal, and the compound leaves and leaf morphology are also very different The landlord can identify the species if he changes a ** It is a hairy mandala and a comparison of leaves.

The leaves of this potato are all zigzag, so they have no medicinal effect, that is, they are useless.

Different varieties have different leaf shapes, such as the shape, size, logarithm and density of the leaflets, and the leaflet axis. What to do if the leaves of Fugui bamboo are yellow What to do if the leaves of the fortune tree are yellow What to do if the leaves of the fortune tree are yellow Gardenia cultivation methods and precautions.

The leaf surface of the potato is densely hairy, a lanceolate type and a top head-shaped, with the effect of collecting water vapor in the air, some varieties also have the effect of resisting pests, connected with the main stem at the base of the compound leaf petioles, there is a pair of lobed leaf brackets on both sides of the joint, which is sickle-type, leaflet type or intermediate type, and the shape of the leaves of different varieties is different.

Hello dear, when the potatoes are ripe, the leaves will be yellow-brown or wilted, and they will gradually fall to the ground. This is because when the potatoes are ripe, the nutrients have been completely transferred to the tuber, and the leaves no longer need to continue the nutrients**, so they will gradually wilt. At this time, if the potato tuber is dug out, you can see that its surface has changed, the skin has become thicker, the skin color has darkened, and a dry and hard protective film will be formed on the surface of the epidermis, which are all signs of potato maturity.

It is important to note that withering potato leaves does not necessarily mean that all tubers are ripe, and it may take some time for some tubers to fully mature. Therefore, before digging potatoes, it is recommended to observe the growth and decline of potato stubble to confirm that the tubers are fully mature before digging.

Potatoes are a plant.

The scientific name of potato is potato is as early as 5000 years ago by human cultivation and cultivation, and different regions have different names for it, in Northeast China, Hebei and other places called potatoes, North China is called yam eggs. Originally cultivated as an ornamental plant, a French agronomist discovered that the tubers of the plant were edible and later used to make bread.

1. Planting time.

The temperature difference in China is relatively large, and the time of potato planting is different in different regions. Generally speaking, potatoes are grown in most parts of the country from October to December every year, and of course they can be planted at any time if the temperature in this area is about the same throughout the year. In some parts of China, potatoes are planted from April to May, such as Northeast China, and there are also two crops in February, March and August, such as Hunan and Shanxi.

There are also two seasons of planting in January, February and September, such as Zhejiang. So the time to plant potatoes is basically determined by temperature, so you can decide when you start planting according to the temperature of your area.

2. Planting method.

1. Land selection and land preparation.

If you want to have a high yield of potatoes, the choice of land is very important, try to choose the soil is more fertile, the soil is more loose, and the sandy land is the best for potato planting. Secondly, when preparing the land, dig as deep as possible, make the soil a little finer, and then apply base fertilizer, which can not only eliminate the weeds planted in the field but also prevent diseases, so that the potatoes can grow better and bear more and bigger potatoes.

2. Seed treatment.

Potatoes should be taken out more than ten days before sowing, germinated at a certain temperature, and then waited until most of the potato sprouts grew to the length of the fingernails and moved to the outside for a week, and cut the place where the potatoes had sprouts before sowing, and a potato could be cut into three or four pieces according to the germination situation, and then stained with dust, and then it could be taken for sowing.

3. Field management.

When planting, it is necessary to plant at certain intervals, because the growth of potatoes in the ground needs enough space, otherwise the potatoes will grow small and the yield will be low. The second is to carry out a fertilization when planting, and the fertilizer should be mainly farmhouse fertilizer as much as possible, and it can also be a water-soluble fertilizer for fertile leaves.

The potatoes should be inspected when they are flowering, because at this time the potatoes will have some diseases, which will seriously affect the quality and yield of the potatoes, so it is necessary to be very careful. As for weeding in the field, it is necessary to be especially Western European Ashin, do not pull out the roots of potatoes, especially during the flowering period, if the roots are loose, the yield will be reduced, and the whole plant will die.

Of course, potatoes belong to plants, and potatoes do not belong to the fruit of plants, but to stems.

Potatoes do not belong to the fruit of the plant, but to the stem. Because botanically, the fruit grows on the ground and is the fruit of the plant's flower after fertilization, and the edible part of the potato is the tuber, that is, the part that grows in the soil.

When and how potatoes were planted.

1. Planting time.

The planting time of potatoes is generally at the end of March every year, and you need to wait for the soil to thaw and the ground temperature is about 18, you can plant; Advance planting can be carried out, and at the beginning of March, the soil is tilled so that the potatoes are kept in a cooler environment and avoid growing in high temperatures.

2. Renovate the soil.

In the potato planting time and method, it is also necessary to turn over the soil again, use tools to turn out the adult old soil and fixed soil, and then bury the new soil, the renovation time is best in sunny weather, which can effectively increase the oxygen content in the soil, make it more breathable, and the planted stems will grow faster.

3. Stem treatment.

Choose a healthy potato mother plant, wash it with water, and cut it into small pieces with a tool, the size of the small pieces is about 3*3 cm; Soak the cut stems in rooting water for 5 hours, then wrap them in a clean towel and place them in a cool place for germination, and after 10 days, the stems will grow buds.

4. Planting method.

Bury the treated stems in the soil, and place the germinated end on top of the soil, without mulching; Then lightly wet the soil with water; If you are planting potatoes on a large scale, the distance between each hole is 15 cm, and they are covered with breathable mulch after planting, and you can also use Trim water-soluble fertilizer, which can be harvested after 3 months of planting.

Potatoes are plants.

Potatoes generally refer to potatoes.

Potato (scientific name: Solanum tuberosum L.).), an annual herbaceous plant with edible tubers, is the fourth most important food crop in the world, after wheat, rice and corn.

Potatoes are also known as artichoke, potato, artichoke, fragrant potato, artichoke, mountain artichoke, artichoke, ground egg, potato, etc. (Shanxi Datong area is also known as yam). In some southern provinces, it is also called "winter potato" because it is often planted in winter after harvesting autumn rice. Potatoes are called different in different countries, such as Irish jicama in the United States, Dutch potatoes in Russia, apples in France, pears in Germany, beans in Italy, and Baba in Peru.

Together with wheat, rice, corn and sorghum, it is known as the world's five major crops. 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. Potatoes are native to the Andes Mountains of South America and can be cultivated in southern Peru from about 8000 to 5000 BC.

The main potato producers are China, Russia, India, Ukraine, the United States, etc. China is the world's largest producer of potatoes.

Potato, scientific name potato, belongs to the Solanaceae family, an annual herbaceous plant with edible tubers, and is the fourth most important food crop in the world, after wheat, rice and corn.

Of course, potatoes are plant-based. But there are many kinds of plants. Potatoes are potatoes, and he is also one of the vegetables. So it's for cooking. And the nutritional value of potatoes is still very high. It is just a part of the plant.

Potatoes are the fruit of plants and should belong to a type of plant. There is no problem that belongs to plants.

Potatoes belong to the stem organs of plants

A potato, or potato, is the tuber of a plant, and although it grows in the soil, it is not a root, but a stem. Its tubers are edible, and the tubers in the section are relatively abundant, which can provide people with calories, and also contain a lot of nutrients, which is a relatively important food crop.

Potatoes are native to the Andes Mountains of South America and can be cultivated in the southern region of Peru from about 8,000 to 5,000 BC. The main potato producers include China, Russia, India, Ukraine and the United States. China is the world's largest producer of potatoes.

Growth habits of potatoes

The growth and development of potatoes is also cyclical, which can be roughly divided into four stages:

1. Mature tubers can be used as seed potatoes for sowing liquid seeds 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 luxuriation 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.

The potato is its tuber, not the root. Germination occurs everywhere on the stem. There are a lot of small sprouts on the potatoes you see, and they can sprout.

After germination, it is poisonous and cannot be eaten.

The primary leaves of potatoes are single-leafed, full-margined, and gradually form an odd number of unequal pinnate compound leaves with the growth of the plant.

The leaflets of potatoes are usually alternate in size, 10-20 cm long, and the petioles are about cm long. leaflets, 6-8 pairs, ovate to oblong, largest 6 cm long and cm wide, smallest less than 1 cm long and wide. In addition, the leaves of the potato are sharp at the apex, slightly unequal in length at the base, entire, pubescent on both sides, 6-7 lateral veins on each side, slightly curved at the apex, and the petiole is about 1-8 mm long.

Newly harvested potato tubers cannot germinate under suitable conditions, and the phenomenon that it must take a considerable time to germinate is called dormancy, and the length of this period is called dormancy. The length of the dormancy period is closely related to the species and storage conditions. Some varieties have a dormancy period of up to one month, while others have a dormancy period of only one month, and even newly harvested tubers can germinate, which is determined by the genetic characteristics of the variety.

Potato growing environment

Temperature: Sex likes cold and cool, does not tolerate high temperatures, and the average daily temperature is 17 21 during the growth period.

Light: high light intensity, high leaf light and action intensity, early tuber formation, high tuber yield and starch content.

Moisture: The transpiration coefficient of potatoes is between 400 600. If the total rainfall is between 400 and 500 mm and evenly distributed over the growing season, the water requirement of the potatoes can be met.

Soil: Plants have very strict soil requirements, and the soil with deep topsoil, loose structure, good drainage and aeration and rich in organic matter is the most suitable, especially the soil with large porosity and good aeration, which can better meet the oxygen needs of root development and tuber growth.

Nutrition: The growth and development of potatoes require more than ten kinds of nutrients, and the demand for fertilizer is the most potassium, followed by nitrogen, and the least phosphorus.
