When are potatoes harvested? When are the potatoes harvested

1. Northeast China and Gansu, Qinghai and other northwest regions.

It is generally planted in spring (mid-to-late April to early May) and harvested in autumn, and usually only one season of potatoes can be planted a year, which is called the northern and northwest one-season cropping areas.

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 during the autumn rice harvest to plant a 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 potatoes.

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 emergence, through photosynthesis.

Produce organic matter, use the root system to absorb water and inorganic elements, and 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.

Potatoes are grown in different regions and are harvested at different times, generally in June-July or October-November.

In the south, potatoes are generally harvested in October-November each year, because the climate in the south is warmer, potatoes can be grown in summer and autumn, while in the north, the climate is colder, potatoes are generally grown in summer, and they can be harvested in September-October.

The timing of the harvest of potatoes is also determined by local weather conditions and market demand, and sometimes the harvest may be earlier or delayed.

It takes 90 days for potatoes to be harvested after plantingHowever, because of the different areas and times of sowing, the ripening time will also be different, Gansu and Northeast China planting potatoes are usually sown in April, and they will mature in autumn, but most of the potatoes planted can be matured between 2 and 3 months.

Potato growing environmentPotatoes need 5 8 to germinate when they are first planted, and the temperature is best controlled between 15 and 20 during the growth stage, and if the temperature is higher than 25, they will stop growing, and most places are usually sown in October, and they can ripen in January and March of the following year.

Potatoes can be planted with peanuts after ripe harvesting, and sufficient soil nutrients are conducive to the growth of peanuts, green onions, celery, garlic and rice are more suitable for planting after potato harvesting, and some areas can continue to plant after harvesting potatoes.

1. Cut into pieces to promote germination. Germination begins 20 days before sowing in early March. When the potato seeds are diced, each piece has at least one bud eye.

10 15 catties is appropriate. After cutting, sterilize and disinfect the water-soaked seeds with small ash dry mix or carbendazim powder 1:200 times.

After the seed block is dried, the seedbed germination will begin, and there are two methods: one is to use sand to germinate in the corner of the house above 15 at room temperature, and a layer of sand and a layer of seed blocks; The second is to dig a pit in the east and west direction of the outdoor ventilation and sunrise to promote germination, the pit is about 25 cm deep, a layer of sand and a layer of seed blocks, 3 layers are appropriate, and then the arch shed film covers, and the grass curtain is covered at night. The above two methods should be sprinkled with water 1 2 times during germination to prevent drying.

When the buds grow to a long centimeter, sowing begins.

Second, land preparation and ditching. Look at the soil moisture before planting, if the moisture is not good, you can consider irrigation ditch moisture, and the moisture building period should be 7 to 10 days before planting. Potato planting is generally double-furrow planting, and 50 cm in large rows and 40 cm in small rows can be used when ditching.

3. Sowing and covering film. The spring equinox to Qingming is the best period, and it should be particularly mentioned here that detoxified potatoes can be sown early in advance, and the plant spacing can be controlled at 20 cm before the spring equinox.

Before sowing, spray along the ditch with 1:10,000 times water of octaposulfuric acid to prevent underground pests. Organic fertilizer can be sprinkled directly in the ditch or during land preparation; Chemical fertilizers can be placed in ditches or sprinkled between blocks (be careful not to come into direct contact with the blocks).

When sowing, there are two ways to put the seed block into the ditch: one is that the seed buds are facing downward, and the potato roots grown by this method are strong and strong, the potatoes are few but the pieces are large, but the seedlings are 2 3 days late; Another method is to plant buds facing upwards, and the roots of potatoes grown by this method are relatively short, the potatoes are small but numerous, and the seedlings are 2 to 3 days early. After the end of planting, take soil from both sides of the big row, cover the space of the potato ditch and the small row, and add a microfilm cover to compact it.

Fourth, seedling release and seedling management. After Qingming, about 20 days after sowing, there are seedlings exposed to the soil, at this time, the seedlings can be washed to break the microfilm and release the wind to prevent steaming seedlings. When the seedlings grow to 10 cm high, the membrane around the seedlings is pressed tightly with soil to retain water and press the grass.

Potatoes should not be watered in the early stage of growth, and then watered after they see flowers. If there is no rain, you can water every 10 days, generally watering 2 or 3 times to mature, and stop watering 10 days before harvest. Prevent insect pests such as aphids or thrips at the seedling stage.

Fifth, reasonable fertilization. Potatoes like to apply farmhouse fertilizer, 4000 5000 catties per square meter is appropriate, and at the same time, nitrogen, phosphorus, and potassium should be used together when applying chemical fertilizer. Potatoes have a large demand for potassium, and the scientific and reasonable ratio of nitrogen, phosphorus and potassium fertilizer is:

1：。Potatoes like to absorb ammonium nitrogen and absorb more sulfur. According to experiments, for every 1 kg of potassium sulfate fertilizer, the yield of potatoes can be increased by 100 150 kg.

Potatoes are propagated from tubers, cut into chunks according to the sprouts, and sown in March. It is necessary to prepare the land and sow the seeds in a timely manner, so that the whole growth period of potatoes is in a relatively cold and low temperature season, so that the formation and expansion of potato nuggets avoid the high temperature period. I remember that Yanhuang Weishi mentioned that it is generally planted together with 4-5 people.

I want to plant potatoes now, can I plant them at the end of April?

Potatoes are harvested in the spring from March to May, after maturity the plant will turn yellow, the stems and leaves will gradually wither, at this time you can harvest, the harvest is best in the morning or afternoon, to prevent the potatoes from wilting in the sun, in the process of breeding, to provide fertile and nutrient-rich soil for potatoes, and to water frequently, so that the soil remains moist.

Potatoes are generally harvested in late June to early July.

It is a sign of maturity when the plant turns yellow, withers and the stems stop gaining weight, at which point it is ready for harvest.

The harvest time is generally before 9 o'clock in the morning or after 5 o'clock in the afternoon, when the temperature is relatively low, and the dug potatoes are not easy to break the skin.

Potatoes are an annual herb with edible tubers and are the fourth most important food crop in the world, after wheat, rice and maize.

Potatoes are also known as yam eggs, artichoke, potato, artichoke, fragrant potato, artichoke, mountain artichoke, artichoke, ground egg, potato, etc.

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 generally harvested at the end of June to the beginning of July, the sign of its maturity is that the plant turns yellow, the rhizome gradually withers, the stem stops gaining weight, the harvest time is usually before 9 am or after 5 pm, the temperature is relatively low at this time, the dug potatoes are not easy to break the skin, in the process of planting potatoes, it is necessary to apply trace elements once every 2-3 weeks.

Abundant compound fertilizer.

Potatoes are generally harvested in late June to early July, depending on the climatic conditions of the growing region and the time of sowing.

Can be harvested in June-July, in the southern region.

It can be harvested in May-June.

When harvesting potatoes, it is necessary to choose the right time, usually before 9 am or after 5 pm, these two time periods, the temperature is low, there is no strong light exposure, and the potatoes will not break the skin, otherwise the quality of potatoes will be affected.

Potatoes like cold and cool, not tolerant to high temperatures, the average daily temperature is 17-21 during the growth period is suitable, and potatoes are a light-loving crop, in light intensity.

Under large conditions, the leaves will photosynthesize rapidly.

As a result, tubers are formed, increasing the starch content.

Potatoes 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 high aeration, which can better meet the oxygen needs of potato root development and tuber growth.

Potatoes are harvested in the spring from March to May, after maturity the plant will turn yellow, the stems and leaves will gradually wither, at this time you can harvest, the harvest is best in the morning or afternoon, to prevent the potatoes from wilting in the sun, in the process of breeding, to provide fertile and nutrient-rich soil for potatoes, and to water frequently, so that the soil remains moist.

Potatoes grown in the north can be harvested in June and July, while in the south the temperature is warmer, they can be harvested in May and June.

Potatoes prefer to grow in soils rich in organic matter and deep soils, so they are planted by adding well-rotted farmyard manure to the soil and mixing the fertilizer with the soil to provide a fertile environment for potatoes to grow.

Potatoes are suitable for growing in moist soil, and should be watered more during the breeding process, which can be watered with rice water to keep the soil moist, and during heavy rains in summer, it is necessary to build a canopy or cover the potatoes with film.

Potatoes can be planted in March in the spring, before sowing, choose potatoes full of young shoots, cut them into evenly sized pieces, and put them in disinfectant water to sterilize, then remove the potato pieces and bury them in the soil, and then cover them with straw to keep warm and moisturize.

The time it takes to harvest potatoes depends on factors such as the variety, growing environment, and planting time. In general, potatoes need to be harvested after the aboveground parts have yellowed, usually from 90 to 120 days after planting. Therefore, depending on the climate and planting time in different regions, the harvesting time of potatoes may vary.

In southern China, the most suitable varieties of potatoes are early and medium ripening, which are generally sown in spring and begin to ripen around July, preferably in the morning or late afternoon when the temperature is cooler. In the northern region, the potato varieties suitable for planting are late-maturing varieties and medium-late maturing varieties, which are sown in the spring like a clear and begin to mature around August. Harvesting is done only after the aboveground parts of the potatoes are yellowed, which ensures that the potatoes are fully ripe, have a better taste and are of better quality.

In short, the time of harvesting potatoes needs to be determined according to factors such as region, variety and growing environment, and it is recommended to make appropriate adjustments according to the actual situation.

Depending on the region where they are grown and the time of day, the time of harvesting will vary. Potatoes planted in the spring in the northern regions are generally harvested in June and July. In the south, when planted at the same time, the harvest can be made in May and June due to the relatively high temperatures.

Soil closed reed bean belongs to the Solanaceae family, an annual herbaceous plant with edible tubers, and potatoes are one of the four important food crops in the world.

Potatoes can also be called potatoes, potatoes, sweet potatoes, potatoes, eggs or potatoes. The sedan bean contains a lot of starch, and potatoes have long become the second staple food in European and American countries, especially in North America.

Potatoes are native to the Andes Mountains of South America and have been cultivated in the southern part of Peru from around 8,000 to 5,000 BC.

Hello, potatoes are harvested in September and October. Potatoes are a seasonal crop, and their growth and harvest time are affected by geographical and environmental factors such as temperature and climate. Generally speaking, the harvest time of potatoes is about 80-120 days after planting, that is, 3-4 months after planting.

The exact timing of the harvest also depends on the growing region and climatic conditions, but it can be earlier in warmer areas and some delays in colder climates. Generally speaking, the harvest time of potatoes is more common in autumn, such as September and October, but there are some varieties that are more suitable for harvesting in spring, such as March and April, and in warmer regions, it can also be harvested in multiple seasons in a year. It should be noted that the specific time of potato harvest should also be selected according to factors such as the growth of the potatoes, their ripeness, and the needs of the harvester.
