How should sweet potato cultivation be managed? How do you grow a well shaped sweet potato?

Sweet potatoes are also widely cultivated and are also a popular root crop. However, how to taste the planted sweet potatoes well is directly related to the effect of sweet potato planting. Let's take a look at this issue.

How to grow sweet potatoes to make good shape. Before this question, let's analyze the factors that affect the quality of sweet potatoes. The normal condition of sweet potatoes is that the potatoes are of a dignified shape and have a smooth and beautiful skin.

Abnormal potatoes are deformed, with cracks, cracked skin, or spots of decay.

Once you know the reasons for the poor quality of sweet potatoes, you can solve these problems. When planting sweet potatoes, choose not clay soil, but choose sand and soil where sweet potatoes are grown, or add enough high-quality soil miscellaneous fees to the fields where sweet potatoes are grown, so that you can avoid lumpy deformities caused by hardening soil. Prevent the arable land from rising to sprinkle avelina or neo-yellow phosphorus particles, kill needleworms, earthworms and other underground pests, gnaw on sweet potato roots, and prevent holes or spots in sweet potato roots, affecting the quality of sweet potatoes.

When it is found that the water is insufficient during the growth of sweet potatoes, it is necessary to water it in time to keep the soil moist to prevent sudden rain after excessive drought and prevent the skin of the potato from cracking. By preventing underground pests in time and creating a suitable environment for the growth of sweet potatoes, sweet potatoes can obtain good conduct, smoothness, beauty and ideal benefits. Sweet potatoes have a "spindle-shaped" and "top-shaped", so how can you judge that they are a good shape?

In my opinion, at least it has the characteristics of smooth epidermis, no cracks, no damage, no insects, full hair, no deformity, etc., and it is a good condition and good shape.

How do you grow sweet potatoes to make good shape? Personally, I think that combined with this good shape and characteristics, based on actual experience, the following points can be done to grow a beautiful sweet potato 3360

The growth organs of sweet potatoes control the vines, especially during the swelling of sweet potatoes, and are good at mastering fertilizer management. Regarding whether the sweet potatoes are deformed, cracked, full, and high in the later stage, specifically, the rattan should be removed on the sweet potato extruder, leaving 2 3 rattans, and then fertilizer should be added according to the standard of 40 kg of potassium fertilizer and 10 kg of phosphate fertilizer per mu. At the same time, the conservative state of the surface clods is guaranteed to be white but not cracked.

Choose the sand and soil in which the sweet potatoes are grown, or add enough high-quality soil miscellaneous to the fields where the sweet potatoes are grown, so that you can avoid lumpy deformities caused by hardening of the soil. It is necessary to water in time to keep the soil moist, prevent sudden rain after excessive drought, and prevent the skin of potatoes from cracking.

In order to grow sweet potatoes in good shape, the choice of land is very important. Sweet potatoes that grow in sandy loam soil are in good shape. It needs to be planted together, with base fertilizer and more watering in the early stage.

If you want to grow sweet potatoes with good shape, the choice of land is very important, the shape of sweet potatoes grown in sandy loam soil is better, you should start planting, apply good base fertilizer, and you can water more in the early stage.

Sweet potatoes are commonly planted and are a kind of root crops that everyone loves; However, how to make the planted sweet potatoes look good directly affects the economic benefits of planting sweet potatoes. Sweet potatoes are suitable for the development trend in the soft and rich sandy loam soil, where the sweet potatoes that grow and develop in this kind of soil are generally of high quality, with a smooth and beautiful skin, and belong to high-quality potatoes; But now the land is very desertified, and some of the soil where sweet potatoes are planted is layered and uneven, and the deformity rate caused by the roots of the jujube and bright melon will be very high when sweet potatoes are planted in this kind of soil.

Because the roots of sweet potatoes grow and develop underground, they are the favorite food of needleworms and grubs; In the Pengda stage of sweet potato root blocks, if there are needleworms and grubs in the fields where sweet potatoes are planted, they will eat the side potato pieces, causing small holes or marks on the potato pieces; and even create gaps. Manipulate the rattan during the growth period of sweet potato, divide the bench wide with good fertilizer liquid, especially in the sweet potato Peng time to master the fertilizer and water management, and close the sweet potato to the second half of the leaf whether it is deformed, cracked, rounded, or high gross output value.

Try to actually say that during the sweet potato swelling period, cut off the main vine, vacate 2 3 secondary vines, and improve the organic fertilizer according to the specifications of 1 mu of 40kg potassium fertilizer and 10kg of phosphorus and potassium fertilizer. In addition, make sure that the stones on the ground are white but not cracked. Although sweet potatoes are not as delicate as other vegetables and fruits, they are difficult to remove, but they need to pay attention to their characteristics; Sweet potatoes are resistant to drought and waterlogging, especially in the early spring in the southern region, with abundant precipitation, so we must pay attention to the drainage pipes.

Even if planted in the spring, do not water more than half of the ridge surface.

Sweet potatoes belong to the underground root crops, and soil stratification is very important for them. Thick soil stratification, loose soil stratification, fertile sandy loam soil is very conducive to the growth and development of sweet potatoes, in this kind of soil stratification, sweet potatoes can be "carefree" stretch their waists, down roots, Peng Da, not easy to cause the situation of squeezing, but also reduce the occurrence of sweet potatoes "gnashing teeth" perhaps.

It is necessary to pay attention to the condition of the soil, be sure to pay attention to the density of planting, and carry out reasonable watering and fertilization, so that you can grow a better shape.

It is necessary to carry out planting, but also to supplement farm fertilizer in a timely manner, grasp the growth period, do a good job in water and fertilizer management, and supplement organic fertilizer in a timely manner.

When planting sweet potatoes, we must first choose a sunny field, and then we must weed it and ensure sufficient moisture, so that it can grow into a good shape.

Sweet potatoes are suitable for growing in soft and rich sandy loam soil, and sweet potatoes grown in such soil are generally of noble character, with smooth and beautiful skin, and belong to high-quality potatoes; However, the soil is very clumped now, and there are some potholes in the soil where sweet potatoes are grown, and when sweet potatoes are planted in such soil, the root deformity rate of sweet potatoes will be very high. Sweet potato growth period to manipulate rattan, distribute liquid fertilizer, especially in the sweet potato Peng period to grasp the fertilizer and water management, close to the later stage of sweet potato is not deformed, cracked, is not round, is not high yield. What must actually be said is that during the expansion period of sweet potatoes, the main vine is cut off and <>

After leaving 2 or 3 secondary vines, increase chemical fertilizer according to the specification of 40kg of potassium fertilizer and 10kg of phosphorus and potassium fertilizer for 1 mu. At the same time, make sure that the ground stones are white but do not crack to lock in water. Since all the whole process of sweet potato growth is in the ground, it is necessary to clean all the insect pests in the field before the sweet potato seedlings are planted into the field.

After subsoiling the land resources, it will be exposed to the sun for ten days and half a month, which can only kill some poor survivability pests and bacteria. In order to completely eliminate these larvae such as white ants, ground tiger larvae, root bugs, root aphids, needleworms, and beetles in the ground, it is necessary to further avoid and <>

The simplest and rude way for farmers is to prevent, spray, the present invention is applicable to soil, 90% dichloromethane aqueous solution 800 times, 50% light phosphorus moisturizing emulsion 500 times, lasting 8 to 10 days, 2 to 3 days of continuous use. Caused by sweet potato diseases and insect pests: sweet potatoes are caused by the harm of underground pests, or caused by the imbalance of nutrients in the internal structure caused by ciliate brown spot and other injuries.

Although sweet potatoes are not as delicate and difficult to manage as other vegetables and fruits, it is still necessary to pay attention to their characteristics;

Sweet potatoes are drought tolerant and not waterlogging, especially in the early spring in the southern region, with abundant precipitation, so be sure to pay attention to the drainage pipes. Even if planted in late spring, the watering should not exceed half of the ridge surface. Sweet potatoes are underground root crops, and the soil is crucial for them.

The sandy loam soil with thick soil layer, loose soil and rich soil is very conducive to the growth of sweet potatoes, in such soil, sweet potatoes can stretch their waists "freely", take root downward, and will not appear to be compressed and squeezed, and it is also possible to reduce the occurrence of sweet potatoes "gnashing teeth".

It is necessary to strengthen the management of water and fertilizer, especially in the swelling period, to remove the main vine, to properly sterilize and kill insects, but also to set the value.

It is important to set the value well in advance and to avoid soil compaction. Proper pruning of branches and foliage should also be carried out to avoid imbalances of water and fertilizer.

1. Planting and applying enough farm fertilizer, pad straw or wood flour.

Second, during the growth period of sweet potatoes, timely control and reasonable fertilizer and water.

3. Ensure that the insect is exterminated at least three times to ensure that the sweet potato is free of insect eyes.

Fourth, pay attention to excavation to prevent man-made damage.

1, turning the seedling vine this method is often used sweet potato control measures, after many years of practical application, is an effective method, 2, the rainy season to control the prosperity, sweet potato planting after about two and a half months, encountering high temperature and high humidity weather is very normal lack of bushes, abundant rain, fertile and permeable soil, often cause sweet potato seedlings to appear long, if the cherry tree does not take measures to control the growth of the sweet potato seedlings, sweet potato seedlings will have adventitious roots at the leaf nodes.

3. Sweet potatoes are planted for about three months, and it is also necessary to control the vigorous growth of seedlings, so that the nutrients produced by sweet potato leaves can be turned to destroy the storage roots of sweet potatoes as much as possible, so that the sweet potatoes can expand rapidly.

4. Drug control growth, about 30 40 days after sweet potato planting, seedlings and vines grow, foliar spraying can be carried out 1000 times liquid uniconazole or chlorbutrazole, etc

The subject asks how to grow sweet potatoes to grow good shapes? Before this question, let's analyze what are the factors that affect the quality of sweet potatoes? The normal appearance of sweet potatoes is that the potato shape is upright, and the skin is smooth and beautiful; And the abnormal potato shape is deformed, there are cracks, when planting, according to the dosage of 3000 kg per mu, the hole is first applied enough pig manure or cow manure and other farm fertilizer, and then paved straw or wood powder and then compacted the soil.

The use of this method for planting can not only increase the fertilizer efficiency, but more importantly, improve soil compaction and increase air permeability.

Sweet potato is an underground tuber crop, the growth of the whole fruit, development and maturity, are completed underground, we can not see, not like the fruit ripening crop on the ground, the whole growth process we can observe at any time, including the flowering of the fruit, fruit setting, ripening are completed under the nose, rain or irrigation problems, the weather is dry when the sweet potato is born, and the amount of water is too large in the later stage, resulting in the sudden growth of sweet potatoes too fast and causing cracks The field is too small, and the planting is too submerged.

<> sweet potatoes are not as delicate and difficult to take care of as other fruits and vegetables, but it is still necessary to pay attention to their characteristics; Sweet potatoes are drought tolerant and not waterlogged, especially in early spring in the south, where there is plenty of rain, so you must pay attention to drainage. Even if planted in late spring, irrigation should not exceed half of the ridge surface. First of all, you have to choose a good sweet potato variety, and let me say that I really don't know what there is.

We generally divide white sweet potatoes, yellow sweet potatoes, and watermelons
