How do you grow sweet potatoes when they sprout? Can sweet potatoes be used as seed potatoes when th

Sweet potatoes can't be planted in the north after they sprout, but I think they can be planted in the south because the stems of sweet potatoes are cut in the south and planted by cuttings.

Sweet potatoes are harvested in autumn, and if they are not stored properly, they will definitely sprout. If this happens, first prepare the ground, apply rotten farmhouse fertilizer, sprinkle an appropriate amount of plant ash to ensure that the soil is loose, and then put the sprouted sweet potatoes, be careful not to hurt the shoots that have begun to germinate, according to one direction, head to tail connection, the buds that have begun to appear are placed in an orderly manner, and then covered with fine soil after 2 3.

This is done in April, if there is a drought, the sweet potatoes should be sprinkled with water to ensure that the sweet potatoes sprout smoothly, when the sweet potatoes start to pull the vines, it is also in May, the stems with a few leaves are cut on the lush sweet potato vines, and after the rain, or in the afternoon, the ridges are planted.

I think the sprouted sweet potatoes can be in the south, and most of the seedlings in the north are raised by fire kang, and if they are carried in the process, they will definitely hurt the germinated shoots, so the quality of the sprouts will be affected after the sweet potatoes germinate.

The climatic conditions in the south allow for this. Because I saw in the rural areas of Chongqing District, sweet potatoes are planted with branches, and they are easy to survive.

Sweet potatoes are not new to us, sweet potatoes can often be seen in daily life, in the countryside, sweet potatoes are also planted by more people, and sweet potatoes are still a more suitable crop for planting in the countryside in the north and south, so we are still more familiar with sweet potatoes, this year's autumn has passed, and the sweet potatoes planted in the spring can also be harvested after a period of time.

So some netizens asked, how to plant sweet potatoes after they sprout? For this topic, farmers talk about their views, in the countryside there are planted sweet potatoes should know, the autumn harvest back sweet potatoes are stored for the winter, in the spring when the temperature warms up, some of the sweet potatoes placed outside will send out sweet potato sprouts, these sprouted sweet potatoes in our general will pile it into the soil for seeding.

In our place, the planting of sweet potatoes is generally planted by cutting sweet potato vines, raising sweet potato vines is first in the ground to apply enough fermented and rotted farmhouse fertilizer, and then the sprouted sweet potatoes are piled in the soil, let it grow sweet potato vines, and when the sweet potato vines grow more vigorously, you can ridge in the field where the sweet potatoes are planted ready to be planted by cuttings.

When planting sweet potato vines, we generally choose to cut them after the rain or in the evening of the eye, cut the sweet potato vines back before cutting the sweet potato seedlings, and then cut it into a small section, generally a small section of the sweet potato vine leaves 3 5 sections of leaves, when the sweet potato seedlings are planted, if the soil is relatively dry, it is necessary to water a small one to keep the soil moist, so that the sweet potato seedlings can be better rooted.

After cutting sweet potato vines, it is necessary to do a good job in the management of fertilizer and water in the later growth, and do a good job in cultivating weeding and soil cultivation, so farmers personally believe that after the sweet potatoes germinate, they can pile the sprouted sweet potatoes into the soil, so that after it grows sweet potato vines, you can use sweet potato vines to plant sweet potatoes.

Sweet potatoes can be planted when they sprout, but it generally no longer grows sweet potatoes, when its vines grow, cut a piece of vines and plant them in the ground, and the newly planted vines will grow sweet potatoes later. If it's a white-fleshed sweet potato, it doesn't usually sprout on the surface, but it does grow seeds.

Look at the kind of sweet potatoes that sprout first: put the sweet potatoes in the seedbed in the spring, cover them with film, and the seedlings will grow to about 20 cm and start transplanting in the field!

How to grow potted plants when sweet potatoes sprout, let's take a look.

Summary. Wash the sprouted sweet potatoes and place them in a well-ventilated place to air dry. Wait until the germinated part is cut off after drying, soak in water and wait for rooting, and then you can plant it in the soil after the root growth is completed, pay attention to the reasonable layout of planting, and maintain a distance of at least 30 cm between each planting pit to avoid them asking for nutrients from each other.

Kiss, yes.

Wash the sprouted sweet potatoes and place them in a well-ventilated place to air dry. Wait until the germinated part is cut off after drying, soak in water and wait for rooting, and then you can plant it in the soil after the root growth is completed, pay attention to the reasonable layout of planting, Zheng Wuqing must maintain a distance of at least 30 cm between each planting pit, so as to avoid them shouting and asking for nutrients from each other, after burying in the soil, you need to water the root water, require watering thoroughly, and the planting is completed after quietly watering.

Sweet potato itself is more like the milder and moister air hole locust imitation, in the early stage of planting every day need to be watered, the amount does not have to be much, keep the soil moist in the Ming Hall, and wait until the later stage of the young sprout Kina fiber grows up can reduce the number of watering, about once a week.

<>In general, sweet potato seedlings can germinate (root) after about 5 days.

When the ground temperature is 10, the potato seedlings will not take root.

When the ground temperature is 15, it takes about 5 days for potato seedlings to take root.

When the ground temperature is 17-18, the potato seedlings will take root normally.

When the ground temperature reaches 20, it only takes about 3 days for potato seedlings to take root.

When the local temperature reaches 27-30, it only takes 1 day for potato seedlings to take root.

1. How many days does it take for sweet potato seedlings to germinate?

1. Potato seedlings. 1) If the soil temperature is 10 about 8 cm below the surface, the potato seedlings will not take root.

2) If the soil temperature is 15 about 8 cm below the surface, it takes about 5 days for potato seedlings to take root.

3) If the soil temperature reaches 17-18 about 8 cm below the surface, the potato seedlings will take root normally.

4) If the soil temperature of about 8 cm below the surface reaches 20, the potato seedlings can take root after about 3 days.

5) If the soil temperature of about 8 cm below the surface reaches 27-30, it only takes 1 day for potato seedlings to take root.

2. Seed potatoes. 1) After burying the seed potatoes in the soil, the open part (covered with straw) will germinate in about 15 days, and if the current temperature is low, it will take about 20 days to germinate.

2) When the temperature is 25, the stem and leaf growth rate of sweet potato is faster, and the higher the temperature, the faster the stem and leaf growth, but when the temperature is more than 30, it will affect the expansion of the tuber. When the temperature exceeds 38, the respiratory consumption is high, and the growth of stems and leaves is slow.

3) When the temperature is lower than 20, the stems and leaves grow relatively quickly, stop growing when the temperature is lower than 15, and when the temperature is lower than 10 for a long time (or encounter frost), the stems and leaves will die.

2. The influence of ground temperature on potato cubes

During root bulging, a large temperature difference between day and night is conducive to root swelling and nutrient accumulation.

1. When the ground temperature is between 21-29, the higher the temperature, the faster the formation rate of tubers, and the greater the number, but the tubers are smaller.

2. When the ground temperature is 22-24, it is conducive to the formation of tuber roots. When the ground temperature is 20-25, it is conducive to root expansion.

3. When the ground temperature is lower than 20 or more than 30, the expansion rate of the tubers is slower. When the ground temperature was lower than 18, some sweet potato varieties stopped expanding. When the ground temperature is lower than 10, the sweet potato is susceptible to cold damage, and when the ground temperature drops to -2, the tuber root is frozen.

The main process of sweet potato seedling planting is seed selection, sowing, fertilization, seedling pruning and loosening soil, disease prevention and harvesting.

Seed selection: Sweet potato planting looks simple, but good seed selection is also the basic condition for high yield of sweet potatoes. We generally choose a relatively large sweet potato, so that it grows strong buds and has strong vitality, so that it is basically okay.

Sowing: When sowing, soak the sweet potato seeds in the Duoling solution for about ten minutes, which can effectively prevent sweet potato diseases. Finally, cover the seed potatoes with a layer of straw or rotten wood, and then cover them with a thin layer of soil.

When the sweet potato seedlings have grown thirty or forty centimeters, we have to cut them. Then cut three leaves into small sections and then take them for planting, and each plant is about 25 cm apart. It is best to choose fertile soil, and sweet potato fields can be irrigated and drained.

Fertilization: After the growth of sweet potato seedlings is stable, it is necessary to fertilize once, and pig manure and urine water can generally be applied. The second fertilization is for the growth of seedlings, and urea can also be added with compound fertilizer. Finally, there is strong fruit fertilizer, which is generally used with potassium fertilizer and boron fertilizer.

Pruning the seedlings and loosening the soil: If the seedlings grow too much or too densely, we do a pruning to cut off the excess branches and leaves. When the weather is dry, irrigation should be carried out, and weeds should be removed in the medium term to loosen the soil, which is conducive to the growth of fruit potatoes and the absorption of nutrient water.

Disease prevention: The general harm to the growth of sweet potatoes is leaf rollers, aphids, grubs and mice. We can use trichlorfon to spray insect infestation. Rats are generally booby-trapped, where rats' favorite food is mixed with rodenticide to trap rats.

Harvesting: Generally in September or October, we have to cut the sweet potato seedlings, and then dig out the sweet potatoes, dig the sweet potatoes carefully not to dig the surface of the sweet potatoes, and store the dug sweet potatoes in a ventilated cellar, so that the sweet potatoes can be put for a longer time and will not rot.

How to grow potted plants when sweet potatoes sprout, let's take a look.

Sweet potatoes germinate, and the sprouts are maintained in a water bottle to promote the growth of the roots. Transplant in loose and fertile soil to ensure the permeability of the soil and water thoroughly. The transplanted sweet potato seedlings should be maintained in a ventilated and bright place to avoid strong sunlight.

It can also be placed directly in the water and leave half of the sweet potato outside after a few days, and the sweet potato seedlings will grow.

Wash the sprouted sweet potatoes and dry them in a ventilated and cool place. Freshly sprouted sweet potatoes are kept in bottles filled with water and wait for the shoots to grow. After the growth of the buds and leaves is stable, the sweet potato is placed in a water basin to keep the general roots on the outside to promote the continuous growth of the roots.

After the roots of sweet potatoes grow, they can be transplanted in loose and fertile soil, and mud and sand stones are added to enhance the air permeability of the soil. The sweet potato shoots are planted in the soil, covered with a layer of soil, watered thoroughly to ensure that the soil is in a moist state, and when the temperature is low, it can be covered with a thin film on the soil surface to cool down and moisturize.

After transplanting, sweet potatoes should be maintained in a ventilated and breathable place to ensure the scattering of sunlight and avoid strong sunlight, which will cause sunburn on the leaves. In the process of growing sweet potato shoots, watering should be thoroughly watered to avoid root rot caused by stagnant water, and watered once a day to ensure that the soil is in a moist state.

Sweet potato teeth can be propagated hydroponically, and the sprouted sweet potatoes are fixed in a clean and transparent water bottle, leaving half of the sweet potatoes outside. Change the water every day to ensure that the water quality is clear, maintain it in a ventilated and bright place, after 4 to 5 days, sweet potato seedlings will grow, and when there is a leaf, you can transplant and plant.

If the area of sweet potato germination is relatively large, you can directly bury the vigorous side of germination into the soil, if there is only a small piece of germination, cut off this part, dry and deflated in a cool place and bury it in the soil, wait for a week and then water, after the quarrel, regularly and quantitatively watering and fertilizing, and breed in a ventilated and sunny place.

If there are more sprouted parts of the sweet potato, you can directly bury the whole sweet potato into the fertile soil, if only a small piece of germination, you can cut off this part, put it in a cool place to dry the incision slightly, and wait until it is a little shriveled up and buried it in the pot soil, or directly break off its sprout belt root system and bury it in the soil for breeding.

The best time to plant sweet potato sprouts is in the spring, when the temperature and humidity are more suitable, after planting into the soil, wait for a week and then water, and then water every 5 days or so, water organic fertilizer every 20 days, keep the temperature between 15 and 25 degrees, and put it in a place with sufficient light and good ventilation, such as balconies and windowsills.

Sweet potato germination can not only be cultivated in the soil, but also can be cultivated in water, the sprouted sweet potatoes are cleaned, put in a vase to add an appropriate amount of water aquaculture, pay attention to the dew half in the air, the other half soaked in water, after a period of breeding growth is getting better and better, the later stage can be promoted to the base Wang line proper pruning, every 1 2 weeks to change the water.

Sweet potatoes and purple potatoes are also considered this kind of food, and many people think that potatoes cannot be eaten after sprouting, because they think that they also contain a toxic substance produced after potatoes are sprouted - solanine. But in fact, potatoes belong to the Solanaceae family, and sweet potatoes are sweet potatoes, which cannot be generalized.

Potatoes do not produce any toxic substances after germination, but after germination, some of the nutrients in the tuber are absorbed by the sprouts.

The second is that the nutritional value is higher after germination.

For example, after soybeans, mung beans, peas, and wheat sprouts, they are actually bean sprouts or vegetable seedlings that people especially love to eat. When they sprout, they not only contain richer vitamin C, carotene and dietary fiber, but also have many active ingredients with health care effects that will increase exponentially, so they can achieve a more healthy effect.

In addition, the most common peanuts in life can actually be eaten after sprouting, and the vitamin C content in them will also increase, and there is also resveratrol, a substance that is good for human health.

However, many sprouted peanuts are mostly due to improper placement and moisture, which leads to mildew, and this moldy peanut must not be eaten.

The third type: poisonous after germination can not be eaten.

In fact, in life, there is basically one kind of sprouted food that cannot be eaten - potatoes. As mentioned earlier, potatoes that turn green and sprout produce toxic solanine.

This substance is actually secreted by potatoes to protect themselves from pests, but unfortunately it is toxic to the human body. The scariest thing is that this substance is stable in both hot and cold environments, so no matter how much we cook it, we can't kill it.

In addition, many people in life are more frugal, and will cut off the sprouted part of the potato and eat the leftover. However, the dietitian in the nutrition class does not recommend this.

Because the toxins in potatoes will spread, but the content will be relatively small, and the human body has an immune system, so there may not be any major problems. It's best to throw it away just to be on the safe side, though.
