How to grow sweet potatoes to grow good shape?

How to grow sweet potatoes to grow good shape? Sweet potatoes are known as sweet potatoes in rural areas of our country and sweet potatoes in some places. Sweet potatoes are an easy crop to grow, and you can have good yields if you grow them casually.

In the past, farmers used it to raise pigs and cattle, etc., and later found that sweet potatoes were very useful and had great benefits for the human body when eaten. Its potato leaves can be used as vegetables, and sweet potatoes can be made into various foods, such as: baked sweet potatoes, pot syrup, fried potato cakes, processed potato chips, French fries and other manufactured foods, which are very popular in the market and expand public procurement.

Sweet potatoes belong to the vines in life, which like heat and are afraid of cold. There are no requirements for environmental conditions. In order to achieve their true yield, sweet potatoes must be cultivated in a favourable environmental condition.

Such as temperature, water, light, soil, and nutrients.

<> temperature; The most suitable growing temperature for sweet potato is 20 32 , and its temperature range is best controlled between 15 35. Growth stops below 15 and is inhibited above 38. When the temperature is below 10, the tubers and fruits will suffer from cold damage.

Therefore, when planting sweet potatoes, it must be done at a stable temperature of more than 15 percent. Therefore, planting sweet potatoes is generally sown after the temperature rises in spring, and generally speaking, the planting time is around April and May, and it can be harvested in September. Water; Although sweet potatoes are drought tolerant, they are also moisture-loving.

In order to obtain high yields, the soil moisture content is required to be between 60% and 80%. The water requirement is less at the beginning of growth, and the water content of stem and leaf tubers should be significantly increased in the middle stage, and the soil water content should be maintained at 70-80%. However, it should not be too wet, as it will cause the vines to grow wildly, and the yield will be low.

Illumination; Sweet potatoes belong to light crops, which are easy to turn yellow leaves due to lack of light, fall off when severe, and have low yields in rainy weather. Sufficient sunlight and sunny weather are conducive to increasing the yield of sweet potatoes, and there should be at least 9 hours of light a day, sufficient light is conducive to photosynthesis.

Soil; Sweet potatoes do not have high soil requirements and can be grown in general soil. Growing sweet potatoes with cohesive and non-porous soils does not achieve the yield of sweet potatoes. In order to achieve high yields, it must be a sandy loam with a deep layer, loose soil and strong air permeability.

Only sandy loam soil with deep soil layer, loose soil and strong air permeability is conducive to the growth and development of sweet potato roots and fruits. Sweet potatoes grown in this sandy loam soil have smooth skin, bright colors, ***, and high yields.

It is necessary to choose sandy loam soil suitable for the growth of sweet potatoes, sprinkle avermectin or phosphine granules, and if there is insufficient moisture, it is necessary to water in time to prevent sudden rainfall after excessive drought, resulting in cracking of the skin of potato pieces.

Add pine needles or perlite to the soil, bury the roots that have sprouted in the soil, pay attention to the nutrients in the later stage, and place the sweet potatoes in a sunny place for maintenance.

During the growth period, it should be managed regularly, and attention should be paid to watering, pay attention to the management requirements during planting, and water and fertilizer management should be carried out, so that it can grow into a good shape.

Sweet potatoes grown in such soil are generally of good character, with smooth and durable skin, and belong to high-quality potatoes; But now the soil is very compacted, and some sweet potatoes are planted with lumps of soil, and when you grow sweet potatoes in such soil, the deformity rate of the roots of sweet potatoes will be very high. Farm manure such as pig manure or cow dung is applied to the cave first, and then straw or wood powder is laid and the soil is pressed. The use of this method for planting can not only increase the fertilizer efficiency, but also more importantly, improve the soil compaction, increase air permeability, let the sweet potato grow and reduce the yield of extrusion, which is conducive to expansion, and the output of sweet potato skin is smooth, especially during the expansion of sweet potatoes to grasp the fertilizer and water management, whether the sweet potatoes are deformed, cracked, full, and high yield.

Specifically, during the swelling period of sweet potatoes, after removing the main vine and leaving 2 or 3 secondary vines, fertilizer is added according to the standard of 40 kg of potassium fertilizer and 10 kg of phosphate fertilizer per mu.

<> development and maturity are completed underground, we can't see it, unlike the fruit ripening crops on the ground, we can observe the whole growth process at any time, including the flowering, fruit setting, and ripening of the fruit are completed under the nose, so if you want the sweet potato to be in good condition, although the sweet potato is not as squeamish as other fruits and vegetables, it is difficult to take care of, but we still have to pay attention to its 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.

When ploughing, two bags of phosphate fertilizer, one bag of organic fertilizer, and half a bag of potassium sulfate compound fertilizer per acre! The purpose of ploughing is to plant sweet potatoes, only in this way can we ensure that the sweet potatoes grow slender, slender and beautiful! March to April of the lunar calendar.

At the beginning, in this way, sweet potato seedlings from the potato to maturity, experienced five or six months of process, during this period, there is drought, there is also a surplus of rain, resulting in changes in soil structure, sweet potatoes are easy to grow into strange shapes, there are big round egg shapes, we have to choose two or three years have not planted sweet potato plots, to avoid heavy stubble caused by the aggravation of pests and diseases, sweet potatoes have a bad impact. Therefore, we need to choose a plot of rotation for planting sweet potatoes.

First, when planting sweet potatoes, it is necessary to choose sandy loam soil suitable for the growth of sweet potatoes, rather than choosing clay soil, or apply enough high-quality soil miscellaneous fertilizer to the field where sweet potatoes are grown, so as to avoid deformity caused by soil hardening.

Second, sprinkle avermectin or phosphine granules when arranging the land to kill underground pests such as needleworms or grubs, and prevent these pests from biting the sweet potato roots and causing small holes or patches on the sweet potato roots, which will affect the quality of the sweet potatoes.

Third, in the process of sweet potato growth, once it is found that the water is insufficient, it is necessary to water it in time to keep the soil moist and prevent sudden rainfall after too much drought, causing the skin of the potato to crack.

In short, as long as the underground pests are controlled in time and a suitable growth environment is created for sweet potatoes, sweet potatoes will be in good condition, smooth and beautiful, and obtain ideal benefits.

First, the soil for planting sweet potatoes should be particular. The best soil for planting sweet potatoes is sand-sand-filled soil, which is loose and has good drainage. Sweet potato tubers thrive when grown in soft sandy soil.

Second, sweet potato irrigation. Although sweet potatoes are not as delicate and difficult to care for as other fruits and vegetables, 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.

Third, how to fertilize to avoid only vines and no rhizomes? At the beginning of planting vine seedlings, many farmers will use their own organic fertilizer to sprinkle in the soil as base fertilizer, drench the root water and let it grow, and then sprinkle nitrogen fertilizer after the vine seedlings grow to promote the growth of the seedlings. Apply potassium fertilizer when the sweet potato grows rhizomes, and do not apply nitrogen fertilizer, otherwise there will be seedlings.

Fourth, pest control. Common diseases of sweet potatoes include sweet potato soft rot, ground tiger, mole cricket, potato nematode; Personal recommendation: avermectin, emamectin benzoate, chlorantraniliprole or cytraniliprole, etc., low toxicity, high efficiency, more environmentally friendly, safe.

1. Variety. Only varieties with spindle-like genes are likely to grow spindle-shaped sweet potatoes. The spindle-shaped sweet potato varieties include Longshu 9, Shangshu 19, Qinshu 5, Xushu 32, Qinshu 8, Xinong 431 and so on.

2. Detoxified potato seedlings. The use of detoxified sweet potato seedlings helps to maintain the original seed nature of sweet potatoes, reduce the influence of viruses on the shape of sweet potatoes, and keep the spindle-shaped sweet potatoes unchanged.

3. Cultivation measures. Keep the soil loose and ridge to avoid the soil being too hard, and the sweet potatoes will not be able to take root, and they will be round. Keep the soil moisture appropriate to avoid drought, sweet potatoes are affected by drought in the early stage of expansion, which will cause the epidermis to age, easy to deform, crack and sprout.

Reasonable fertilization and complete nutrients are also necessary conditions for growing spindle-shaped sweet potatoes.

Sweet potato likes slightly acidic sandy loam or loam soil with fertile soil, deep soil layer, loose and good air permeability, such soil is loose, breathable, good water and fertilizer retention, in order to ensure the normal formation and rapid expansion of sweet potato shape, so that the sweet potato block is neat, the skin is smooth, and the yield and quality are high.

First of all, it is necessary to choose the soil suitable for the growth of sweet potatoes, and secondly, once the water is found to be insufficient in the process of sweet potato growth, it is necessary to water it in time to keep the soil moist. Creating the right growing environment for sweet potatoes will give them a good shape.

That's what people say all the time. Eat in the dark, look at the white seedlings. This means that the black soil is nutritious.

Grows a lot of food. White soil is this sandy soil. Growing food is not very efficient.

But the sweet potatoes grown are particularly delicious.

Black soil, high soil compaction, dense soil, easy to agglomerate. Very detrimental to the formation and expansion of sweet potatoes. The sweet potatoes that grow are balls and balls in our local language, not smooth.

And the survival rate is slightly lower than that of sandy soil. The taste is also poor, and the yield is not high. Although sandy soil has a low nutrient content, it can be compensated for by proper water and fertilizer, but sandy soil has loose soil and large voids.

Well ventilated. Even at high temperatures. The surface temperature is also not too high.

Sandy soils have fewer pests and diseases compared to other soils. Very good for the expansion of sweet potatoes. Sweet potatoes like sandy loam and sandy soil, with deep soil layer, rich organic matter, looseness, aeration, and good drainage performance.

When the soil is heavy and sticky, the root bark is not good and rough, the shape of the potato is irregular, the yield is low, and it is not resistant to storage. However, sandy loam and sandy soils generally have low fertility and poor water retention. Fertilization should be cultivated gradually through measures such as fertilization to obtain high yields.

Sweet potatoes are more resistant to acid and alkali, and the pH value is in the range, but it is appropriate. When the soil salt content is exceeded, sweet potatoes should not be planted.

Sweet potatoes are best grown in sandy soils. The soil is loose and it is easy to grow smooth sweet potatoes. After ripening, the sweet potato is not easy to hurt when planing, and it is not easy to lose.

After we harvest the sweet potatoes, many people go to the sweet potato fields with shovels to dig sweet potatoes. There are fewer sticky sweet potatoes in the sand, and more sticky sweet potatoes in the black soil. As a result, sweet potatoes are generally grown in sandy areas.

Pure sand has poor water retention, which is not conducive to the absorption of water and fertilizer by the root system, and produces relatively few sweet potatoes. If it is pure soil, the root permeability is poor, respiration is inhibited, and the sweet potatoes produced are not sweet enough and taste bad. Therefore, neither pure sandy soil nor pure soil is the most suitable soil for growing sweet potatoes, while sandy soil that is half sandy and half soil has a certain permeability to the root system and can also retain water and moisture to absorb nutrients from the soil.

The soil, which produces sweet potatoes, is not only fat, but also of good quality and sweet taste, which is more suitable for growing sweet potatoes.

Although sweet potatoes like to be dry and afraid of waterlogging, they should not be too dry. If there is too little water, water it in moderation! If you plant sweet potatoes to get sweet potato starch, be sure to harvest it before the solar term "frost falls"!

You can choose sandy soil with fertile soil, deep soil layer, good air permeability and drainage, and sweet potatoes can be grown in such soil.

Sandy loam soil or loam land, pay attention to the deep soil layer, loose and fertile, so that its drainage performance will be better, and to choose a sunny slope, so as to be conducive to the growth of sweet potato, to achieve the effect of increasing yield and income.

I think you can grow better sweet potatoes by choosing more fertile soil with better drainage.

Sweet potatoes are one of the most common in our daily life, whether it is on the street or in the alleys, sweet potatoes are also more popular among people. Many countrymen like to grow some sweet potatoes, its potato leaves can be used as vegetables, sweet potatoes are a delicious food that can be made into a wide variety of foods. Such as:

Baked sweet potatoes, fried potato cakes, processed potato chips, potato chips and other manufactured foods, sweet potatoes were one of the important foods in China during the war years. So, how can a farmer grow a big, round sweet potato without chemical fertilizer?

<> here's how farmers grow sweet potatoes: In ancient times, farmers used the most common method of land preparation, which was to choose a loose, transparent, sandy soil and use dark tanned land in advance. Because in the past, farmers planted crops and could use very little fertilizer, generally ploughing the land early in advance, allowing sunlight to shine on the soil and killing latent bacteria in the soil, so that the crops would be reduced by pathogenic bacteria, reducing the morbidity of crops.

By drying the soil early, the nutrient content in the soil is improved, which is conducive to the drying of the soil, the reproduction of microorganisms in the soil, the early drying of the soil, the improvement of the nutrient bright imitation foci content in the soil, and the early development of the root system is conducive to vigorous development and high yield.

It also reduces the growth and damage of weeds, so people choose to bask in the sun on dry soil in advance before planting crops. In the same way, the ancients often said that "after the winter soil, the day will rise", and there will be a good harvest next year. Select 6-7 potato vine seedlings, the next 4 potato leaves are removed, and the sweet potatoes are planted according to the furrow, the ridge height is 30 cm, the ridge surface is 30 cm, and the bottom width is 60 cm.

The depth of the ridge in the ditch is 20 cm, the sweet potato seedlings are inclined at an angle of 45 degrees, straight or inverted cuttings, the plant spacing is 25 cm, about 3,000 trees per mu, and then sprinkled with a large number of plant ash mixed seeds, "There are a large number of plant ash potatoes." Then cover the soil 10 cm, cover the soil and cover the next 4 sections, the upper two sections are seedling growth, the lower 4 sections are sweet potato fruits, and after covering the soil, close to the potato seedlings are lightly pressed, and one can be watered.
