How are potatoes grown? What are the potato growing conditions?

1. Germination period.

The growth of potatoes begins with the germination of buds on the tubers, and only when the tubers are released from dormancy can the buds and seedlings grow significantly. From bud germination to emergence, the first stage of the main stem grows.

2. Seedling stage.

From the emergence of the seedling to the flattening of the sixth or eighth leaf, that is, the growth of one leaf inflorescence is completed, which is called "tuan", which is the second growth of the main stem, which is the seedling stage of potato. The seedling stage passes for a short period of time, and only half a month for both spring and autumn cropping.

3. Hair period.

From the clump to the twelfth or sixteenth leaf, the early-maturing varieties bloom in the first inflorescence; Late-maturing varieties bloom in the second inflorescence, which is the flowering period of potatoes, which lasts about one month, and is the growth of the third stage of the main stem.

4. Potato setting period.

That is, the formation period of the tuber. After the flowering stage is completed, it enters the tuber growth stage. At this stage, the growth of stems and leaves decreases day by day, the basal leaves begin to turn yellow and wither, and the organic nutrients of each part of the plant continue to be transported to the tubers, and the tubers then expand faster, especially after 10 days after the flowering period.

1. Temperature:

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

2. Lighting:

The light intensity was high, the leaf light and action intensity were high, the tuber was formed early, and the tuber yield and starch content were high.

3. 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.

4. Soil:

Plants have very strict requirements for soil, 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 needs of oxygen for root development and tuber growth.

5. Nutrition:

The growth and development of potatoes requires more than ten kinds of nutrients, and the demand for the three elements of fertilizer is the most potassium, followed by nitrogen, and phosphorus.

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.

1. Northeast China, Gansu, Qinghai and other northwest regions, generally planted in spring (mid-to-late April to early May), harvested in autumn, usually only one season of potatoes can be planted a year, called the north and northwest one-season cropping area.

2. Shandong, Hebei, Henan, Shanxi, Jiangsu, Hunan, Hubei and other provinces and regions plant 2 seasons of potatoes a year. Among them, Shandong, Hebei and other Central Plains sown spring potatoes in months and harvested in June-July; Autumn potatoes are sown in August and harvested from the end of October to the beginning of November; Some provinces in central and southern China, such as Jiangsu and Zhejiang, sow spring potatoes in January and February, and harvest them in May and June; It is sown in September and harvested in December. These areas are called the Central Plains and Central and South Cropping Areas.

3. Guangdong, Guangxi, Hainan, Yunnan, Guizhou and other places can use the gap between the autumn rice harvest to plant one season of potatoes. Generally, it is sown from mid to late October to November, and harvested from February to March of the following year. Because the growing season is mostly in winter, these areas are often referred to as the southern winter cropping areas.

The growth cycle of the potato.

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

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 and raising the reed to maturity, that is, the tuber formation stage.

How long is the potato growing season.

The growth cycle of potatoes is about five months. In general, the growth cycle of different varieties of potatoes is different. The growth cycle of early-maturing potatoes is about four months, while the growth cycle of late-maturing potatoes is relatively long, about six months or more.

The growth and development stages of potatoes are generally seedling stage, budding stage and fruiting stage. In addition, different varieties of potatoes are generally planted at the same time, but harvested at different times. They are all planted in April, and the ripening time of early potatoes is September, and the ripening time of late potatoes is October.

The growth process of potatoes.

1.The seedling period is relatively short, and the early and late maturing varieties Tuanlu have a seedling period of half a month. 2.

Early-maturing varieties bloom in the first inflorescence, and late-maturing varieties bloom in the second. This stage is known as the flowering stage of the potato and usually takes a month to crack the potato. 3.

The length of the seed setting period of potatoes is generally different. There is a difference between early and late ripening potatoes, but it is generally about 30 to 50 days.

Potato maintenance and management during the growing season.

1.Seedling maintenance: The seedling stage does not need too much nutrients and water, so the main control temperature should not be too low.

2.Maintenance during the growing period: At this stage, it is necessary to water in strict accordance with the principle of less watering to avoid excessive soil moisture.

3.Maintenance of potato fruit set: water and fertilize on time during potato fruit set, and ensure that there is enough light time.

Potatoes are grown through the following growth and development processes.

1.Dormant period. Potatoes do not germinate for a long time even if they are placed in a suitable environment for growth after harvesting, which is the physiological dormancy period of potatoes.

The dormancy period of potatoes begins to dormant when the underground tubers begin to swell, and its length is related to the storage temperature, the dormancy period will be shortened if the storage temperature is relatively high, and the dormancy period will be extended when the storage temperature is relatively low. In the past, northerners used potatoes as their main vegetable, so they used to cellar potatoes in order to prolong the dormancy period of potatoes. Of course, the dormancy period of potatoes is related to the variety, and the dormancy period varies from about 1 month to more than 3 months in general.

2.Germination period. Potatoes begin to germinate after breaking the dormant period, and thus the growth of potatoes begins.

From bud germination to emergence, it is the germination stage, which is the first growth period of the main stem of potatoes. The center of growth during the germination period is the elongation of the buds, and young roots begin to appear, and even if potatoes are cellared in the north, long buds will grow in the summer, and fine roots will grow on the buds. The nutrients and water required for germination are mainly supplied by seed potatoes.

3.Seedling stage. After the potato is sown, it is flattened from the seedling to the sixth or eighth leaf, and the growth of one leaf inflorescence is completed, which is called "tuan", which is the second stage of growth of the main stem, and this period is the seedling stage of the potato.

The seedling period of potatoes is very short, and although it depends on the variety, it is generally only about 15 days. The root system is gradually formed at the seedling stage, when the required nutrients and water are provided by both the tuber and the soil.

4.Germination period. From the seedling stage to the twelfth or sixteenth leaf, the first inflorescence of the early-maturing variety blooms, and the second inflorescence of the late-maturing variety blooms, this period is called the germination period of the potato, which lasts about 1 month and is the growth of the third stage of the main stem.

From the germination stage, the main stem enters the rapid growth period, all the leaves, branches and branches on the main stem are also rapidly formed, the root system continues to expand, and the tuber begins to expand. During this period, the nutrients and water required for growth and development are completely superior to the soil, so the amount of base fertilizer and the quality of base fertilizer are the key factors for high yield.

5.Tubers. The last and most critical period of the potato growth cycle is the tuber formation.

After the growth period is completed, the tuber setting stage is the center. At this time, the growth of stems and leaves slowly decreases, the base leaves begin to turn yellow or dry up, the organic nutrients of each part of the plant are continuously transported to the tuber, which is the period when the tuber expands and accelerates, and the length of the tuber period is related to the climatic conditions and the maturity of the variety, about 30-50 days, the management center of this period is to cultivate the soil, create a loose soil, the growth environment with a thick topsoil layer, and prevent the tuber from expanding and bare on the surface.

Potatoes are one of the top five crops in the world. It is often on everyone's table. Even in North America, potatoes have become the second largest staple food.

Potato varieties with antiviral resistance, excellent economic traits, and effective prevention of degradation were selected. Acidic hilly land has deep soil layer, fertile soil, good fertilizer retention performance, good water retention and drainage performance, irrigation conditions and subsoiling foundation. Varieties and soil fertility, reasonably dense planting.

Early-maturing varieties should be planted densely, and late-maturing varieties should be sparsely planted. Note that the eyes of the potatoes should be facing upwards so that the sprouts can grow better. The amount of watering varies at different times.

Sprinkler irrigation and drip irrigation are available. When in full bloom, there should be plenty of water; In the early stage of potato fruit set, the water content should be properly controlled; Irrigation should be carried out according to climatic conditions during potato fruit set; Moisture should also be controlled in the late planting period of potatoes and before harvesting. It is better not to drink water.

At the same time, it is necessary to prevent diseases and potato rot.

Proper irrigation can effectively control pests and improve yield and quality. About half a month before sowing, we should germinate in a place with a certain amount of light, avoid direct sunlight, and keep the temperature of the germination site at about 15 to 20 degrees. If there is a cellar, we can sprout directly in the disaster prevention cellar.

Cut into cubes the day before sowing. If conditions allow, a potato can only be cut into a maximum of four pieces.

Make sure that the sprout points of the potatoes are not damaged and disinfected with alcohol. The optimal planting depth is about 15 cm. Grow potato chunks at intervals of 60-70 cm per row and 25-30 cm per plant, following the bud tip upwards.

Finally, cover with a thin layer of soil with a layer of agroplastic film to maintain temperature and promote seedling growth. Potatoes are rich in potassium and can be properly supplemented. It contains a variety of nutrients such as protein and vitamins.

It can appropriately reduce gastric juice secretion and regulate gastric balance. Patients with poor renal function develop edema. Potatoes can be used to reduce swelling properly, are effective for duodenal ulcers, constipation and, eczema, and can lower cholesterol.

First prepare the potato sprouts, then bury them in the soil 10 cm deep, and finally pour water.

The first thing is to germinate the potatoes first, then control the moisture and humidity, plant all the potatoes into the ground, and also apply some potassium fertilizer, and then be sure to weed in time, so that the potatoes are planted.

First of all, fertile soil is needed, and secondly, timely watering and fertilization, strengthening water and fertilizer management and field management, ensuring sufficient sunlight, timely loosening of soil, regular spraying of pesticides, timely removal of insect pests, and also need to do a good job of drainage and ventilation.

Cut the potatoes into pieces, dig a hole in a fertile soil, throw the potato chunks into the soil, cover the soil with some water, and the plant is ready.

Introduction to potato growth.

Potatoes prefer cold and cold environments, and they need cool, moist, loose and breathable soil for the formation and growth of their underground tubers.

The main potato producing areas in China are the southwest, Inner Mongolia, northwest and northeast regions, among which Dingxi City, Gansu Province has become one of the best potato planting areas in the world.

Potato growth cycle.

The tuber of potato formed an enlarged suitable growth temperature at 17 20 and 30 when the tuber stopped growing, and the low temperature of 0 low temperature could cause different degrees of damage to the seedlings, adults and tubers in storage, about 80 days for early varieties and about 120 days for late varieties.

Potato growth rate.

The whole growth process of potato can be divided into six stages: dormant stage, germination stage, seedling stage, tree emergence stage, potato setting stage and maturity stage.

10 days after the potato seedlings are unearthed, the stolons grow out from the base, generally 20 days after the seedlings emerge, the underground stolons grow out, and the horizontal guess book grows, about a month after the emergence of the seedling, the plant begins to bud, and the flowers begin to bloom about 15 days after the buds, the stem and leaf growth enters the vigorous period, and the leaf area increases rapidly.

Potato growth cycle management.

Under normal circumstances, potatoes can easily reach the value of 2000 kg per mu, and the yield per mu can reach 5000 kg and above if the potato is given a suitable plot and scientific management conditions.

Temperature management: The optimal temperature for stem and leaf growth is between 17-21, the optimal temperature for tuber formation and development is between 17-19, and the optimal temperature for flowering is between 15-17.

Shima Zhaoling fertilizer management: When planting potatoes, the principle of fertilization is generally "organic fertilizer, supplemented by chemical fertilizer, heavy application of basal fertilizer, and early application of top dressing", and the most water and fertilizer are needed during flowering.
