How are potatoes grown, how are potatoes grown?

1. Sow seeds, cut the potato seeds according to the sprout eye, generally leave one bud eye, if it is too small, you can leave two. Put one in each hole.

2. Germination stage, from the bud on the tuber to the emergence of seedlings.

3. Seedling stage, from the seedling unearthed to the bud, more than 20-25 days.

4 tuber formation period, this period is centered on tuber growth and is divided into 3 stages. It takes more than 20-25 days from budding to flowering, which is called the early stage of stem formation. The second stage is from the flowering stage to the end stage. The third stage is the starch accumulation phase, which is the end of tuber formation.

5. Dormant period, after the tuber is formed, it enters the dormant period. At this time, the potatoes cannot germinate even if they are placed in a suitable environment, which is called physiological dormancy.

6Uncle the peasant shall take out the potatoes and sell them to you to eat.

After 25 days after planting, the seedlings should be put in time, and the mulch film should be checked at the seedling stage, and if there is a rotten place, it should be re-compacted. If you find that the seedlings do not grow, you should cut the mulch film and let the potatoes grow in time.

Weeding is carried out three times, the first is after the emergence of the potatoes, the second is when the potatoes have grown to 13 cm, and the third is before the buds of the potatoes appear, preferably by hand.

After the weed has grown three leaves, if it is a grassy weed, 100 grams of ethoxydidine can be used or, 60 grams, 12% clethodim. If it is a broadleaf weed, you can use 150 grams of 48% herbicidal pine.

If it is mixed with weeds and broadleaf weeds: 100 grams of 36% potatoes can be used (the seedlings of potatoes should be less than 10 cm), potatoes are more sensitive to herbicides, so you must be cautious when using them, or follow the recommended dosage of herbicides purchased.

1. Site selection.

Choose a well-drained and sunny plot and apply some base fertilizer, either potassium or plant ash. Be careful not to plant potatoes in a field that has been planted for two years, as it will be easy to live.

2. Germination. At the end of December or January, the potatoes to be planted are germinated at a temperature so that they can be planted around February.

3. Incision. Cut the sprouted potatoes into cubes, making sure that each piece has 2 to 3 sprouts on top. After the incision, apply some grass ash to the wound in time.

Fourth, planting. Once the potatoes have been processed, they can be planted, digging a shallow trench in the soil and putting in the cut pieces, about 15 cm apart. After planting, you don't need to water, you can also not fertilize, if you fertilize, you can apply some potassium fertilizer in moderation, do not use urea or human and animal manure, otherwise it will affect the taste.

Fifth, harvest. Potatoes are easy to grow and can be harvested in May or June after planting in February.

When potatoes are propagated vegetatively by tubers, seed potatoes can germinate and grow under the condition of soil temperature of 5 8, and the optimal temperature is 15 20. The temperature suitable for the growth of stems and leaves and flowering of the plant is 16 22 . The most suitable temperature for tuber formation at night is 10 13 (soil temperature 16 18), and the formation is slow above 20.

Frost damage occurs when the temperature drops to -2 at the emergent and seedling stages.

The flowering and tuber formation stage is the period with the greatest water requirement in the whole growth period, and in case of drought, 15 20 tons of irrigation per mu is the key technical measure to ensure high and stable potato yield.

Potatoes generally absorb about kilograms of nitrogen, kilograms of phosphoric acid and kilograms of potassium oxide in the case of a yield of 1330 1650 kilograms per mu. Although potatoes are adapted to a variety of soils, they are best used in loose and organic-rich (black soils). The density of seedlings per mu should not be less than 4,000 plants.

1 Preparation before sowing Dig the ground 24 cm 25 cm deep, and then level. If the moisture is insufficient before sowing, irrigation should be made up 10 days in advance.

2. Fertilizer preparation about 20 days in advance, according to 300 kg of 500 kg of manure per mu, evenly add 25 kg of 50 thousand grams of ammonium bicarbonate, seal and pile it in the sun, mix it well after it is fully decomposed, and apply it and turn it into the soil when turning over the soil.

3 Pre-sowing treatment of seed potatoes.

Disinfect. 120 kg of seeds per mu, and the original seeds are sprayed with 400 times and 500 times of Ruixin mold.

Diced. Cut each seed potato into more than 8 pieces. Because of its apical advantage, try to cut more pieces at the top of the bud eye, and then use 10 mg kg of gibberellin 1 packet to add 10 kg of water to soak the seeds for 5 minutes or add 75 kg of water to spray the seed blocks.

Germination. Place the potato block flat on the suitable moisture pure soil, make the potato sprouts upward, spread 2 cm of soil and then lay a layer of seed potatoes, repeat 3 layers and 4 layers and then spread 5 cm thick soil, pile it in the back of the sun, cover it tightly with agricultural film, and sow it after 15 days.

The above work should generally be done before the middle of January, because the potato in the expansion period if the outside temperature exceeds 25, the tuber will stop growing, and the seedling will grow vigorously, so there must be a suitable growth period of 90 days and 100 days, and sowing should not be postponed.

4 sowing requirements according to the row spacing of 70 cm, plant spacing of 20 cm ditch to the side of the soil, ditch depth 6 cm 8 cm, put seed potatoes to make the potato buds upward, and then cover the soil ridge height 10 cm 15 cm. After compaction, it is covered with mulch, and after the top of the bud film, the film is broken and the soil is covered.

5 Field management When the seedlings grow 3 or 5 leaves, pay attention to the control of aphids. Top dressing at the early stage of budding and full flowering stage, generally 500 times of Phytomyces shirui plus urea or potassium dihydrogen phosphate 1 plus bulking horm. During the tuber expansion period, attention should be paid to strengthening field irrigation to improve yield.

6 Harvest in time Potatoes are of the best quality in mid-June and should be harvested in time

It seems that you can plant it now, go to the market to buy some potatoes and come back, prepare some soil, cut off the one with eyes on the potatoes, and try to cut the big pieces for the first time, the survival rate is high. Make a nest or trough in the soil, if it is in the countryside, it is easier to do, sprinkle some ash and pour some manure, and then put the peeled potatoes with eyes in them, the eyes should be upward, and then cover the soil and wait for it to sprout and grow. I hope you understand, I've planted it many times. Hehe.

The easy way to do this is to first fertilize the land. Plough the floor.

Secondly, there are many eyes on a potato, and a small piece of the whole eye on the potato is cut off, and then planted in the soil that is not very deep, and when the time comes, it will sprout and take root, grow small seedlings, and then grow strongly, blossom and bear fruit. If the potato seedlings grow large and vigorous, then it proves that the potatoes in the field are also growing well...

When the potatoes sprout, bury them in the soil.

Choose a sunny and well-drained plot with a lot of trouble, and apply base fertilizer, generally potassium fertilizer, such as plant ash is very good, or fermented chicken manure. It is better not to choose a plot where the potatoes have been harvested for two years, because then the potatoes are prone to disease and do not grow well. In addition, choose slightly acidic soil, potatoes are not easy to scar.

Potatoes can be planted in December, January and February. If you don't have one, go to the market in February and buy sprouted potatoes. Site preparation.

Remove all the big stones and weeds, it is best to use cooked land, apply base fertilizer, mainly organic fertilizer and potassium fertilizer, and use grass ash for burning wasteland.

At the end of December and January, you can put the potatoes that will sprout in a warm and bright place for germination, so that Sun Xingtong can be planted in February. Small sprouts will emerge from the eyes of the potatoes.

Cut the sprouted potatoes into cubes, large potatoes can be cut into several more pieces, and each piece is guaranteed to have two or three sprouts on it. Wipe the wound of the diced potato with plant ash, or leave it alone. Then put them in the soil, about 15 cm apart from each other.

Potatoes do not need to be watered, because this is the most abundant rain in spring, potatoes can grow without fertilization, if you want to fertilize you can sprinkle some potassium fertilizer appropriately. It is not suitable to use fermented human and animal manure or urea, which can make potatoes unpalatable. Wait until May and June when the potatoes are ready to be harvested.

When planting potatoes, first of all, select high-quality potato varieties, cut them into four parts with a knife, and then put them into semi-dry and semi-wet sandy soil for germination treatment, water them once a day, and then prepare loose fertile soil, cover them with a small amount of thin soil after planting, and apply a small amount of organic fertilizer solution.

Potatoes are one of the crops planted by many vegetable farmers, if you want to plant potatoes with large yields, you must first select high-quality potato varieties, then cut them into four parts with a knife, smear them on the incision with a small amount of carbon ash or sand, and dry them in a dry place for about 2 3 days to strengthen the circulation of air.

Then put the selected potatoes into semi-dry and semi-wet sandy soil, loosen the soil every day, put it in a sunny environment, and remove the surrounding weeds in time, pour a small amount of water every day, and there will be bud roots on the surface of the potatoes in about 2 weeks.

Because potatoes prefer to grow in fertile soil with good porosity, humus, garden soil, sandy soil, and peat soil can be selected according to 3:2:2:

The ratio of 2 is mixed and prepared, and then a small amount of farmhouse fertilizer solution is added to the soil as a substrate, and an appropriate amount of water is poured to keep the potting soil moist.

Put the potato seedlings in the soil, cover them with a small amount of thin soil, keep the spacing of each plant at about 25cm, pour in water in time, and then apply a small amount of organic fertilizer solution, remember not too much, water once a day, and ensure that there is enough light time every day.

When planting potatoes, we should pay attention to planting time, cutting and germination, sowing matters, and watering management.

1. Planting time

The planting time of potatoes varies from region to region, and in the northern region, only one season is planted a year, and it is generally planted in spring and harvested in autumn. Spring potatoes in the central and southern regions of the Central Plains are planted in months and harvested in June and July, and autumn potatoes are planted in August and harvested around November. In the south, the seeds are sown in October and November, and harvested in February and March of the following year.

2. Cut into pieces to promote germination

20 to 25 days before sowing, put the seed potatoes in the sun, and dry them in a warm place for 2 to 3 days, remove the diseased potatoes and rotten potatoes, and cut them into pieces. When cutting, it can be divided into two or four according to the top bud, and each seed potato should have 1 2 sprout eyes and weigh 25 30 grams. After drying the knife edge, it can be placed in the temperature 18 20 indoor for germination, and when the buds grow to about 2 cm, they are dried under scattered light, and the buds are sown after the greenery becomes thicker.

3. Sowing matters

When sowing potatoes, the thickness of the soil should not be less than 12 cm, if the thickness is not enough, the temperature of the ground will change too drastically, and the seeds will easily escape from the ground. If you want to plant potatoes with high yield, you must plant them reasonably densely, large potatoes should be sparse, and small potatoes should be planted intensively, and the sowing density can be adjusted according to the local climate, soil, variety and other reasons.

4. Watering management

Potatoes are generally not watered until they bloom, except in very dry times when a small amount of water can be watered. Watering begins at the beginning of flowering, during which the potato pieces grow too fast and the water demand increases, so you can water, watering once every 7-10 days according to the drought of the soil and the growth of the seedlings, and watering until about 10 days before harvest or after the stems and leaves have stopped.

1. Prepare materials.

Before planting potatoes, the first thing to do is to prepare the "material", that is, the soil and the pot, the soil requirements are not high, as long as it is loose and breathable, with good drainage and fertile, for the pot, it is recommended to use plastic pots, and with ventilation holes. After that, you can cut the potatoes into cubes, and generally each piece needs to have 2-3 bud points.

2. Start sowing.

The materials are ready, and then you can plant, generally before planting, you need to smear some plant ash on the potato pieces, which is better to take root. When planting, dig a shallow trench in the potting soil and bury the potato pieces in it, and the distance between each piece should be about 14 cm.

3. Follow-up management.

Watering: Once planted, it's time to manage. Generally speaking, the potatoes do not need to be watered much when they are in the seedling stage, and they can be watered when the soil is dry.

If you don't know how to judge whether the potting soil is dry, Mushroom Liang teaches you a small method, knock on the wall of the pot with your hand, if the sound is crisp, it means that the potting soil is almost dry or has been dried, and the sound is dull, which means that there is still a lot of water.

4. Fertilization follow-up.

For fertilizers, urea or animal manure is usually not recommended, and some fermented fertilizers containing nutrients can be applied. Compared with the special nutrient solution for vegetables, this fertilizer is made by fermentation of sugarcane, which can be topdressed once every half a month, and after the use of potatoes, it can accelerate the differentiation of flower buds, which is easier to absorb than chemical fertilizers, and the yield will be higher. This potato can be soil-cultivated, in fact, it can also be hydroponic, many flower friends prefer hydroponics because it is more beautiful.
