How long do potatoes grow?

The total growth cycle of potatoes is generally at least about five months, and the growth cycle of potatoes includes dormant period, germination period, and young period.

The seedling stage, the germination stage, and the tuber stage are several processes, and the cycle is different for each stage. The details are as follows:

1. Dormant period:

Because of the different varieties of potatoes, the dormancy period varies from 1 to 3 months or more, at a temperature of 0-4 degrees Celsius for potatoes.

It can be left dormant for a long time.

2. Germination period:

The center of growth in the germination stage is in the elongation of the buds, the roots and the formation of stolons, and the nutrients and water mainly depend on the seed potatoes, according to the stems, leaves and roots.

The length of supply varies from one month to several months depending on the dormancy characteristics of the variety, the cultivation season and the technical measures.

3. Seedling stage:

The seedling stage passes for a short period of time, and only half a month for both spring and autumn cropping.

4. Hair period:

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.

5. Potato setting period:

The length of the tuber setting period is limited by climatic conditions, diseases and variety ripeness, etc., and is generally 30-50 days.

The scientific name of potato is potato, and the growth period of potatoes is usually called the growth period. According to the length of the growth period, it is mainly divided into early-maturing varieties, medium-maturing varieties and late-maturing varieties. The early-maturing varieties take about 60 days from seedling emergence to harvest; Medium-ripening varieties take about 80 days from seedling emergence to harvest; Late-maturing varieties take about 100 days from seedling emergence to harvest.

In addition: it takes about 20-30 days from sowing to emergence of potatoes.

The growth cycle of potatoes.

1. Germination period: from the germination of the buds on the tuber to the emergence of seedlings is the germination period of potatoes. The growth of the germination stage is mainly based on the growth of the underground main stem, which is the basis for potato rooting, potato formation, and ensuring the healthy growth and development of stems and leaves in the later stage, as well as the basis for constituting yield.

The nutrients and water required for tuber germination are mainly provided by the seed potatoes themselves, so for larger seed potato tubers, it is often said that the mother is fat and strong.

2. Seedling stage: It is generally 20-25 days from the emergence of seedlings to the emergence of buds. About half a month after the soil is unearthed, the main stem on the ground forms 6-8 leaves, which is the early stage of the seedling.

After that, the growth of stems and leaves increased sharply, and after the leaves on the main stem were differentiated to 12-16 pieces, the apical bud entered the pregnant bud stage, and when the flower buds appeared in the aboveground part, the top of the underground stolons began to expand, which was the late stage of the seedling stage.

Potato planting area is different planting date, the late potato cycle needs about 110-120, each piece of potato cutting must have a bud germ, the size of the breeding block is different, the strength of the seedlings grown out of the different size of the breeding block, it is recommended that the cut breeding is best to keep the larger potato pieces, keep the seedlings unearthed consistently. The planting depth is about three or four inches, the soil is mainly loose and sandy, the soil moisture can not be too high or too low, the high moisture will make the potato bud germ rot and necrosis, and the lack of water will affect the germination rate. Potato growth cycle is relatively long, the soil must be fertile, generally use sheep manure, horse manure, pig manure and other green organic fertilizers, fertilizer before the need to make fertilizer, in the fertilizer mixed with pesticides, the fertilizer in the eggs killing, pest and disease prevention, mainly to prevent trough insects.

The growth cycle varies from variety to variety, with early maturing varieties taking about 80 days and late maturing products taking about 120 days.

The relationship between potato growth and environmental conditions.

1. Temperature The growth of potatoes requires a frozen climate, with an average of 5-10 degrees per year.

2. Moisture Must be supplied with enough moisture in order to achieve high yield.

3. Photosynthesis There is enough sunlight to grow.

4. Soil The organic content of the soil is a favorable condition for the growth of potatoes, and it also depends on the type and amount of fertilizer applied.

You're going to see what potatoes are: earth potatoes are about 90 days, and potatoes are about 45 days in greenhouses.

Do you know how long the potato growth cycle is? What month does it start planting every year?

About 90 days for the earth and about 45 days for the greenhouse.

Potato growth cycle

1. Germination period: The potato tuber is relieved of dormancy, and the germination period is from bud germination to emergence, and the growth time varies from 1 month to several months.

2. Seedling stage: After the potato sprouts, it grows to the eighth leaf and flattens, which is the second stage of the main stem growth, and the time that passes is short, only half a month.

3. Tree development stage: the potato grows to the sixteenth leaf, and the first inflorescence blooms, which lasts about 1 month, which is the growth of the third stage.

4. Potato setting stage: After the potato germination period is completed, it enters the tuber growth period. The tubers swell at an accelerated pace, generally in 30-50 days.

Technical points for potato planting

1. Choose soil: potatoes have strong adaptability, but it is advisable to choose soil with loose soil and convenient drainage and irrigation.

2. Select excellent varieties: potatoes should be selected with high yield and disease resistance, and seed potatoes should be of moderate size, bright buds and roots, and no diseases and pests.

3. Seed treatment: Dry the seed potatoes for 2-3 days to remove the diseased potatoes and bad potatoes. Large seed potatoes are cut into pieces, the cut seeds are placed in the sun to dry, and then carbendazim is added with plant ash and mixed evenly.

Potatoes are not the same variety, and the growth cycle time is also different.

In general, the growth cycle of early ripening is about 6 days, medium ripening is about 8 days, and late ripening is about 1 day.

It generally takes about 2-3 days from the beginning of sowing to the emergence of small seedlings.

The varieties are different, and the growth cycle is different. It takes about 60 days for early ripening, about 80 days for medium ripening, and about 100 days for late ripening.

Potatoes can be harvested in 3-5 months. Different regions have different ripening times, the northwest is planted in the spring and harvested in the fall, and only one season can be planted a year, which takes 4-5 months. In some areas of the north, it can be planted in two seasons Month Harvest Month Harvest, August Planting, Harvest at the End of October, Need.

Potatoes are planted in October-December, and the growing season is generally around 60 days.

Potatoes are generally planted in October-December, but the specific planting time is related to the local climate, Northeast and Gansu, Qinghai and other northwest are planted in mid-to-late April to early May, Jiangsu, Zhejiang and other central and southern provinces are planted in spring in January and February, and autumn is planted in September. The planting time in Guangdong, Guangxi, Hainan, Yunnan and other places is sown from mid to late October to November.

Generally, the growth cycle of early-maturing varieties of potatoes is about 60 days, the growth period of medium-ripening potato varieties is about 80 days, and the growth period of late-maturing potato varieties is about 100 days. In the process of potato growth, when necessary, the seedlings can be restrained by topping, so that the seedlings can grow stronger. In the process of growth, it is also necessary to ensure good light and ventilation, otherwise there will be vigorous plants and small fruits.

Potato planting

1. Soil preparation and fertilization

Choose sandy loam soils with fertile, flat, well-drained, deep and loose tillage. Before sowing, the land preparation can be deep ploughed and raked, and then made a furrow, the width and height of the furrow depend on the terrain and soil moisture. In addition, when preparing the land, 1500 kg of fully fermented organic fertilizer can be applied per mu, or 200 kg of potassium sulfate compound fertilizer or 50 kg of superphosphate can be applied to the base fertilizer per mu before planting.

2. Seed potato treatment

Choose a healthy seed potato with smooth skin, delicious color, weight of about 1-2 taels for seeding, before cutting seed potatoes, it is recommended to dry the seed potatoes in the sun for 2-3 days, and the cutting knives should be disinfected to avoid bacterial infection of seed potatoes, seed potato cutting should not be too large or too small, try to use the top bud of the seed potato, less use the bottom bud, so as to ensure the emergence rate of potatoes and improve potato yield.
