Sweet potatoes and potatoes commonly grown in rural areas, what should be done if they want to have

1. Sweet potato vine is not turned over, potato seedlings go to the top, 2. Skillfully chase the expansion fertilizer, increase yield and improve quality, 3. Spray foliar fertilizer, increase yield and prevent decay, the soil can not be too arid, drought can easily lead to stunted development of potato pieces.

The best thing to do is to fertilize every other month, so that the nutrients are enough for high yields.

Growing sweet potatoes is profitable, and the management of planting sweet potatoes is labor-saving and time-saving, with less input, but the yield is very high. Eating more sweet potatoes is good for the body, sweet potatoes are selling well, and it's okay.

Sweet potato, also known as sweet potato, is a very common food crop in China, and is an important food crop in China, with the planting area ranking first in the world. Moreover, sweet potato is a fast-growing crop, and its planting technology is relatively simple, and now there is a large market demand for sweet potato tubers and leaves, so there is still a good prospect for growing sweet potatoes.

If you want to have a high yield of sweet potatoes, you must master the planting techniques and methods, and I will introduce the techniques and methods of planting sweet potatoes below.

1. Select a soil plot.

Sweet potatoes are very adaptable to the soil, and they can grow in almost all soils. But if you want to make sweet potatoes have a high yield, it is best to choose acidic sandy soil or light sandy soil with good porosity, strong air permeability, and fineness. Because such soil is conducive to the growth of sweet potato roots and the weight gain of tubers, it is conducive to the growth of sweet potatoes.

2. Seedling selection and seedling raising.

Choose sweet potatoes of moderate size and health, and disinfect them before planting them in the soil, so that they are easier to survive and thrive after transplanting. Secondly, the varieties are different, the seedling raising methods are different, and the root seedling is the more commonly used seedling method. Secondly, potato vine seedling raising is also a seedling breeding method, which is a propagation method that retains the potato vine after the autumn harvest for a winter, and then takes root from cuttings in the second year.

3. Dig holes and plant.

Sweet potatoes require a larger field than other horticultural vegetables, dig holes and control the spacing between holes, and then place the sweet potato seedlings in the pre-dug holes one by one, and then cover them with film to protect the sweet potatoes in cold weather.

4. Later maintenance.

After the sweet potato seedlings are planted, there will often be a lack of seedlings and dead seedlings due to weak seedlings, drought and other reasons, so it is necessary to check and replenish the seedlings in time. Cultivating and weeding should also be carried out frequently, and top dressing should be carried out at least three times, and at the same time pay attention to the time of top dressing to promote the growth and expansion of sweet potatoes. In terms of watering, after watering, it is necessary to cultivate and loosen the soil in time, and try to avoid flood irrigation.

Growing sweet potatoes is not a simple task, not only to have high yields, but also to control the requirements for quality. That's all for the sweet potato growing techniques, and I hope some of my insights will help you.

I think planting sweet potatoes makes money, but when planting sweet potatoes, choose land with relatively fertile and wide soil, and when fertilizing, you must use farmhouse fertilizer, never use fertilizer bought outside, and often water the plants, but also prevent the occurrence of pests and diseases, if there are small insects, then you must spray insecticides in time. But I think the most important thing is that when planting sweet potatoes, be sure to soak the seeds in water for about three hours.

Grow sweet potatoes to make money. First of all, if you want to have a high yield of sweet potatoes, the main method is to reapply basal fertilizer, apply in stages, and spray foliar spray. This allows the sweet potatoes to have adequate nutrients.

Growing sweet potatoes is still more profitable, and it is also very simple, when planting sweet potatoes, you must fertilize and water more, only in this way can you make sweet potatoes bigger and taste better.

Very profitable. Find a suitable environment for growing sweet potatoes, then cut the sweet potatoes into small pieces and put them in the soil, remember to water them more fertilizer and water them on time, so that the sweet potato yield can be higher.

<> high potato yield. Because the potato planting area in China is larger than the sweet potato planting area, and under normal circumstances, the yield per mu of potatoes is between 2000 kg and 4000 kg, and the yield of sweet potatoes per mu is between 2000 kg and 3000 kg. However, the specific will vary depending on subjective and objective factors such as planting technology and climate influence.

First of all, it is necessary to choose a good potato variety, because large potato varieties are the first element of high yield!

The second is the rational application of plantar fertilizer, about 3,000 kg of fermented and rotted farmhouse fertilizer per mu, 150 kg of potassium sulfate compound fertilizer per mu or a bag of special compound fertilizer for potatoes. Choose how you want to plow the field.

1: The choice of seed potatoes, before planting land beans, you should choose high-quality seed potatoes, bright appearance, no broken skin, and high-quality seed potatoes of moderate size.

2: Potatoes are a very strong growing crop, not very susceptible to external conditions, but we should also choose the sowing time according to the growth habits of potatoes in different regions.

3: Growing conditions, potatoes need a lot of water during the growth time, and the moisture content in the soil should be kept between 50% and 60%, which is conducive to promoting the growth of potatoes.

Potatoes have a greater need for light, but they are more strict about light and temperature, and 20 degrees is the most suitable temperature for potatoes at the seedling stage. The temperature of potato tuber growth should be controlled at about 18 20 degrees, higher than 20 degrees, and lower than 18 degrees will try different effects on the growth and development of potatoes.

Sweet potato is a kind of crop that is often planted in rural areas, and sweet potato is a treasure all over the body and has high use value. The young stems and leaves of sweet potatoes can be eaten as vegetables, the stems and vines are an excellent feed for livestock and poultry, and the rhizomes are the food that everyone likes to eat. The transplanted field is ploughed first, then sprinkled with fertilizer, preferably putrid manure (that is, fertilizer after the leaf stalk of the plant has rotted), and then the sweet potato seedlings are planted on the ridges.

It is best to plant after rain, so that there is no need for watering and the survival rate is high.

Poor permeability

Sweet potatoes are crops that grow vines above ground and stem underground. In the process of growth, the photosynthetic nutrients absorbed by the seedlings need to be transferred to the rhizomes, and after planting on flat ground, due to the long stretching of the seedlings and the overlapping of each other, the harvesting function is reduced, so that the rhizomes are malnourished and the quality is reduced, the soil should be fertile, and the bottom fertilizer should be sufficient. The base fertilizer for planting sweet potatoes is best to choose well-rotted farmhouse fertilizer, and then use 30 to 40 kg of potassium sulfate high-potassium compound fertilizer as base fertilizer per mu.

Sweet potato is a chlorine crop, and the application of potassium chloride chloride-containing compound fertilizer is contraindicated.

<> choice of soil quality. Good soil produces good potatoes. Although sweet potatoes are widely adaptable, they can be harvested wherever they are planted; However, the quality and yield of sweet potatoes grown in different soil qualities vary greatly.

What kind of land grows the best quality and high yield of sweet potatoes? Seedling cultivation is a very critical step, which is related to the quality of later transplanted potato seedlings, and even affects the yield in the future, so cultivating sweet potato seedlings is the first step of sweet potato planting. The first thing to do is to choose a flat and open plot of land as a nursery pond.

There are many varieties of sweet potatoes, and it is better to choose varieties that are suitable for your local climate. The second is to choose a good soil, sweet potatoes like sandy loam, it is soft and breathable, there are few pests and diseases, and the color of sweet potatoes is bright. In order to obtain high yield and high quality sweet potatoes, scientifically managed fertilizers and water and a series of cultivation and management measures are indispensable, such as planting seedlings of sweet potatoes, improving the vigorous development of sweet potatoes in the medium and control, expanding and applying foliar fertilizers in the later stages, and so on.

In order to achieve the goal of high yield, cultivating sweet potato seedlings is the foundation. When growing, healthy and intact sweet potatoes can be cut into 2-5 pieces according to their size and germination point, and soaked in water to raise seedlings. After waiting for the sweet potatoes to grow thick sprouts, the sweet potatoes can be transplanted into the soil.

Choosing sandy soil with good air permeability is more conducive to their growth, so as to achieve the purpose of high yield. In addition, the right temperature will make them grow better. It is recommended to maintain the temperature between 22 and 30 degrees Celsius during management.

The first is to cultivate strong seedlings. The high yield performance of sweet potato varieties and the quality of potato seedlings are the internal factors that determine the yield. Only excellent varieties can inherit excellent genes and keep their offspring in excellent traits.

When planting, try to choose robust potato seedlings, therefore, do a good job in potato seedlings, improve the quality of potato seedlings, purify and reinvigorate the seed nature, in order to improve the yield of sweet potatoes. Second, choose fertile soil. Sweet potato is a root crop, which requires deep soil layer, loose, fertile, breathable, and refreshing soil conditions.

The third is to plant at the right time. Sweet potatoes are a thermophilic crop, and the optimal temperature for root formation is 24-25.

First of all, the variety of sweet potatoes should be selected, and secondly, sweet potatoes should be planted in sandy soil with high organic content. After planting, the field management should be regulated.

This statement is not entirely true. Whether it is sweet potatoes in spring or sweet potatoes in summer, some farmers tend to neglect the management of sweet potato seedling stage. In fact, the management of the nursery period is also important.

Seedling inspection and replenishment. After sowing, sweet potatoes often fail to emerge due to drought, insect pests, and other reasons. If seedlings are missing, they must be replenished after sowing.

At the same time, seedlings should be supplemented after slow seedlings to promote growth. In general, the time for replenishing seedlings should not be too late, and it is best to plant 10 to 14 days after planting.

Proper fertilization to promote strong seedlings. The use of sweet potato topdressing at the seedling stage should be determined according to the growth of the plant。Some require top dressing, while some sweet potatoes require foliar spraying.

In the past, in the first year of planting sweet potatoes, the soil fertility was sufficient, but after planting the seeds, I went to see them every ten days or so and found that the seedlings of sweet potatoes grew very slowly. The vines are elongated and it is not known if this is due to the lack of fertilizer and water. Slow growth of sweet potatoes at seedling stage is not a bad thing, because 30 to 35 days after sowing, it is mainly the growth of the root system.

The aerial parts grow slowly, but the leaves are thicker. Sweet potatoes have a good root system, which also means that there will be more sweet potatoes. On the contrary, some sweet potatoes that grow too fast at the seedling stage are closed early, which is not conducive to the growth of sweet potatoes.

Therefore, the management of the seedling stage is very helpful for the later growth of sweet potatoes and tubers.

In plots where the basic fertilizer is insufficient, the sweet potato seedlings are topdressed 15 to 20 days after sowing, which means that the sweet potato seedlings can survive。The leaves are yellow, weak, and the top dressing is mainly nitrogen. For those crops that grow well, some phosphorus and potassium fertilizers can be topdressed, and foliar sprays can also be sprayed.

For example, after the end of the slow seedling, fertilizer is sprayed on the leaves. You can use 50-80 grams of potassium phosphate monobasic per acre, plus 50 ml of amino acids to promote leaf and root growth, which is good for increased yields.

Do a good job in the prevention and control of plant diseases and pests. At the seedling stage of sweet potato, pests and diseases should be prevented and controlled. In the event of illness, medication can be taken in advance**.

Taking pests as an example, every year in June and July, many pests appear, and these pests also damage the leaves of sweet potatoes and reduce photosynthesis, which is not conducive to the formation of sweet potatoes. In such cases, pesticides can be used in advance for prevention and control. After planting sweet potatoes, it enters a slow seedling stage, which is actually the rooting period.

During this period, management is very important, it determines future output, and farmers cannot ignore it. Through the management of the above three aspects, sweet potatoes have thick leaves, well-developed root systems, and strong ability to absorb water and fertilizer. Then, the yield and quality of sweet potatoes will be improved.

You can water the sweet potato seedlings more, apply more organic fertilizer to them, and give them more sunlight at ordinary times, so that the sweet potatoes planted will be very high-yielding.

After the sweet potato seedlings are stabilized, nitrogen fertilizer and potassium fertilizer should be added every day to increase the nutrients of the food and water more, so that the sweet potato seedlings can have a high yield.

When planting sweet potatoes, you must apply some organic fertilizer, and you must water and fertilize regularly and quantitatively, and you must pay attention to insect pest control.

When planting, be sure to pay attention to the surrounding environment, pay attention to the temperature and humidity of the soil, and also pay attention to the time of fertilization.

1. Select the seed. When the temperature rises to 8 10 in spring, open the cellar and select sweet potatoes with no rot and no black spots as seeds. In order to reduce costs, sweet potatoes below 300g are generally selected as seeds.

2. Seed treatment. Seed potatoes that are disease-free and injury-free are selected, the seeds are soaked in water, and then dried until the skin is dry.

3. Plastic film cultivation. 4000 kg of well-decomposed high-quality agricultural fertilizer was applied per mu, 20 kg of potassium sulfate and 20 kg of diammonium phosphate were added, and then ridge cropping. The ridge height is 25 cm, and two rows of sweet potatoes are cultivated.

Sweet potatoes with their heads down allow new plants to germinate from the top buds. The upper part of the small head is more than 5cm above the soil surface. After covering the soil, it is covered with plastic film and then watered to keep the soil moisture up to standard.

4. Pre-excavation treatment. The soil temperature of mulching cultivation is generally 13 15 when the temperature reaches 13 15. When sweet potato seedlings begin to emerge, in order to prevent burning seedlings, when the side buds begin to germinate, part of the soil is removed to expose the upper part of the sweet potato seeds, so as to promote the smooth excavation of sweet potato seedlings.

5. Choose the main vine. Sweet potato seedlings begin to grow, and the first two sweet potato seedlings from the top are retained as the main vine for cultivation. When the remaining sweet potato seedlings grow to 15 to 25 cm, they can be used as sweet potato seedlings**, which can not only recover the cost of sweet potato seeds and mulching, but also obtain a certain economy and income.

In this process, sweet potato seeds need a lot of water and need to be replenished in time according to the soil moisture. Generally, ditch watering is not required for hole application, so as not to drop the ground temperature too much and affect the growth of sweet potatoes.

6. Strengthen water and fertilizer management. Apply 20kg of urea, then use rotten high-quality farmhouse manure and water. Before ridge sealing, apply 25 30kg of potassium sulfate ternary compound fertilizer per mu.

In the middle and late stages, urea solution or potassium dihydrogen phosphate can be sprayed according to the lack of fertilizer to promote the expansion of tubers and prevent premature aging.

7. Harvest. Since sweet potatoes are cultivated 20-25 days in advance, the growth and development of sweet potatoes is significantly advanced. Sweet potato leaves can be harvested in mid-August to feed the pigs.
