How to grow sweet potatoes How to grow sweet potatoes

Known as the "sweet potato king" Lao Tian will plant about 10 acres of sweet potatoes every year, it can be said that he is famous in the local area, many people will ask him to help guide when planting sweet potatoes, and he will also be enthusiastic to help. The sweet potatoes he planted not only have a high yield, with a production capacity of nearly 10,000 catties per mu, but also the quality of the potato pieces is also very good. Let's take a look at how the "sweet potato king" grows sweet potatoes.

Lao Tian said that he will first choose a field with fertile soil, loose soil, good aeration, and easy watering when planting sweet potatoes, because the skin of such a field is smooth, and there are few cracks, and sweet potatoes contain less fiber, so the taste of sweet potatoes is naturally much better.

In addition, Lao Tian said that in the countryside, there are many villagers who plant sweet potato seedlings are planted in the soil, and then water a little to finish, the result is that when the sweet potatoes are harvested, the size of the sweet potatoes is big, the small is small, some sweet potatoes can bear several pieces, some only bear a large one, some form a group of small potatoes, and some do not even bear sweet potatoes. The reason for this situation of sweet potatoes is that everyone ignores the importance of sweet potato seedling planting methods.

More than 10 acres of sweet potatoes in the old field, when planting sweet potato seedlings, the flat planting method requires the length of the planted sweet potato seedlings to be planted in 20 to 30 cm, and the seedlings should be opened along the ridge shallow ditch, and then the seedlings are placed in the shallow soil layer 10 cm deep below the ridge, and the tips of the seedlings are exposed, and the soil is tightly covered. It is through this planting method and then ensuring the fertilizer and water management of the sweet potato field that the sweet potato has achieved a high yield.

Tell you the benefits of choosing the flat planting method: each section of the sweet potato seedlings can take root and set potatoes, there are few empty nodes, there are more tubers, and the size of the tubers is relatively uniform, this planting method combined with good fertilizer and water management, can generally obtain a high yield.

Disadvantages: This planting method has poor drought resistance and is prone to drought, so it is necessary to provide enough water to keep the soil moist, because in the event of drought, high temperature, and insufficient soil fertility, it is easy to lack seedlings or fewer plants, and it will also cause the plant to have insufficient nutrition due to too many potatoes, although there are many potato pieces, but there are few large potato pieces, which ultimately affects the yield of sweet potatoes.

This planting method has been adopted by many large-scale sweet potato growers, and they have achieved good yields, and friends who want to plant sweet potatoes can try it. Or what planting method you choose, you can share it with you.

How to plant sweet potatoes correctly.

Horizontal planting method, oblique planting method, boat bottom planting method, direct planting method, and vine pressing method

1. Horizontal planting method: the seedlings are 20-30 cm long, and the seedlings are distributed in a shallow soil layer about 5 cm deep under the soil surface. The conditions of this method are basically the same, most of the nodes can take root and set potatoes, there are few empty nodes, there are more and uniform potatoes, suitable for plots with better water and fertilizer conditions, and this method is mostly used in large-area high-yield fields in various places.

2. Oblique insertion method: suitable for short seedling planting, the seedling length is 15-20 cm, the seedling is about 10 cm into the soil, the seedling is 5-10 cm on the ground, and the slope of the potato seedling is about 45 degrees.

3. Boat bottom-shaped planting method: the base of the seedling is 2-3 cm in the shallow soil layer, and the middle nodes are slightly deeper, in the 4-6 cm soil layer. It is suitable for plots with fertile soil, deep soil layer and good water and fertilizer conditions.

4. Direct planting method: use short seedlings to insert directly into the soil, and enter the soil for 2-4 nodes. The advantages are high rate of large potatoes, drought resistance, slow seedlings quickly, suitable for hillside land and arid and barren plots.

5. Vine cutting: the potato seedlings are all pressed into the soil, the potato leaves are exposed to the surface, and after planting, they are watered after being compacted with soil.

Sweet potato planting methods: digging holes, planting, mulching film, watering, waiting for tubers to grow, harvesting sweet potatoes.

1. Dig holes. Sweet potatoes require a larger field than other horticultural vegetables. Each hole is 30-60 cm apart. The depth is 3 cm above the base of the plant to the base of the tuber.

2. Planting. Place the sweet potato seedlings one by one in a pre-dug hole and cover the stems with about a centimeter of soil. The leaves of sweet potatoes will grow vines outward, while the roots will grow tubers at a depth of 15-30 cm in the soil.

3. Cover the film.

Protect your sweet potatoes in cold weather by covering them with a film. This will also help to stop weeds from growing into the wild and prevent sweet potato vines from overgrowing, robbing the tubers of nutrients.

4. Watering. When sweet potatoes are first planted, they need a lot of water. Over time, you should water them less until later only about once a week. Start watering daily, then reduce the number of waterings week by week.

5. Wait for the tuber to grow.

Sweet potatoes require a relatively long growth period, and they don't ripen for harvest until early autumn (which happens to coincide with Thanksgiving). Continue to water and weed every week to allow the plants to grow healthily and the dates leak.

6. Harvest sweet potatoes.

About 120 days after planting, the sweet potatoes should have reached full ripeness. If possible, postpone harvesting sweet potatoes as much as possible (before frost), as this will produce larger and tastier tubers.

1. Germination method: When planting sweet potatoes, it is necessary to put the full seed potatoes in a warm environment for germination. 2. Seeding management

Sprinkle sweet potato cubes in fertile and breathable soil. 3. Top dressing fertilizer: After sweet potato seedlings emerge, it is necessary to apply thin manure once.

4. Pruning and topping: Cut the branches that are too long to increase the yield of sweet potatoes.

1. Germination method

When planting sweet potatoes, it is necessary to germinate them, you can select fully ripe and full seed potatoes, and then place them in an environment with a temperature of about 25-30 to promote their rapid germination, and use a sterilized sharp knife to cut the seed potatoes into small pieces, and ensure that each potato contains 1-2 small shoots.

2. Seeding management

Sweet potato is suitable for growing in fertile sandy loam soil, when planting sweet potato, you need to first apply rotten organic fertilizer and cake fertilizer to the soil, and then bury the sweet potato block into the soil, and then cover with a layer of plastic film, wait for about half a month, sweet potato will emerge, at this time the plastic film should be uncovered.

3. Topdressing fertilizer

Sweet potato is a fertilizer-loving plant, it needs sufficient nutrients in the growth process, when breeding sweet potato, it is necessary to apply a thin manure water after the plant emerges, so that its growth rate is accelerated, and in the sweet potato growing season, it is necessary to apply 2-3 times of phosphate fertilizer and potassium fertilizer to increase its yield.

4. Pruning and topping

When breeding sweet potatoes, it is necessary to cut the branches that grow too long to avoid the loss of excess nutrients, and to cut off the withered yellow leaves and diseased branches of sweet potatoes in time to avoid further deterioration of the situation, so that sweet potatoes grow tubers, and after sweet potatoes bloom, they need to be removed in time.

Summary. First, choose high-quality potato seedlings of excellent varieties.

High-yield sweet potatoes are inseparable from high-quality potato seedlings in the first place, and high-quality sweet potato seedlings can improve yield, early tubing, and strong disease resistance. High-quality sweet potato seedlings generally have short internodes, three to five nodes, and the seedling height is 20 to 30 cm.

2. Promote ridge cultivation.

Small ridges are generally cultivated in single rows, with a ridge spacing of 70 cm and a ridge height of 15 to 20 cm; Large ridges are cultivated in two rows, with a ridge spacing of 85 to 95 cm and a ridge height of 25 cm.

How to grow sweet potatoes?

First, choose excellent varieties of high-quality potato seedlings and high-yield sweet potatoes are inseparable from high-quality potato seedlings, high-quality sweet potato seedlings can improve yield, early potato, strong disease resistance. High-quality sweet potato seedlings generally have short internodes, three to five nodes, and the seedling height is 20 to 30 cm. 2. Advocate ridge cultivation Small ridges are generally cultivated in a single row, with a ridge spacing of 70 cm and a ridge height of 15 to 20cm; Large ridges are cultivated in two rows, with a ridge spacing of 85 to 95 cm and a ridge height of 25 cm.

Third, pay attention to the application of potassium fertilizer, sweet potato as a variety of high-yield crops, the demand for fertilizer is also a lot, of which the demand for potassium fertilizer is the largest. The fertilization principle of sweet potatoes is mainly potassium fertilizer, appropriate amount of nitrogen fertilizer, potassium and phosphorus. Fourth, the use of mulch film can be used to plant mulch film in a timely manner, which can prolong the growth period of sweet potatoes and increase the accumulation of nutrients.

What I asked was how to grow sweet potatoes is not a red summer.

Kiss, sweet potatoes are sweet potatoes.

The sweet potato cultivation method is as follows:

1. Land preparation and fertilization: land preparation should be carried out on sunny days, and the soil should be broken and fine. After leveling, the fertilizer strip is applied to the bottom of the ridge, the ridge spacing is 80 cm, and the ridge height is about 20 cm.

Fertilizer can use special organic compound fertilizer, when the planting area is larger, it is required to measure the soil N, P, K and organic matter, and the soil pH value should be measured in the south, and the use of ordinary compound fertilizer is not recommended.

2. Pruning and topping: For potato fields with more branches and more vigorous growth, two or three branches can be cut off with scissors, so that the nutrients can flow back and the potato pieces can get more nutrients. Topping regulates the movement of nutrients and promotes the delivery of nutrients to the roots.

When the seedlings grow to 40-60 cm, the tender tips should be removed, and the tender tips should also be removed when the branches are too vigorous.

3. Timely topdressing: about 15 days after transplanting, the seedling fertilizer is combined with the first tillage to apply 750-1000kg of thin human and animal manure or urea per 667m2. Potato fertilizer is topdressing in the branching tuber stage, which is generally carried out within one month after transplanting in combination with the second tillage, mainly nitrogen fertilizer, combined with phosphorus and potassium fertilizer.

After the stem and leaves are sealed, the growth rate of the root tuber is faster, and the top dressing is applied when cracks appear in the ground. 10kg of top-aurea superphosphate leaching solution per 667m2, 3kg of potassium sulfate mixed with 150-200kg of water to form a nutrient solution, and watering along the seam in the afternoon of a cloudy or sunny day is required to be evenly dressed.

Sweet potato

Jicama root lumpy, spindle-shaped or oblate-spherical, fleshy; pinnate compound leaves, pedicular linear-lanceolate, leaflets rhomboid-shaped or ovate, lobes small, acutely acuminate, racemes, bracts bristle-hairy, early falling; Corolla light purple or reddish, flag petals nearly rounded, wing petals sickle-shaped, columella curved, pods banded, flattened, seeds nearly square, flattened. It is originally distributed in tropical America, Taiwan, Fujian, Guangdong, Hainan, Guangxi, Yunnan, Sichuan, and Guizhou. It likes a warm and sunny environment, and has the characteristics of strong resistance to stress, drought resistance, waterlogging resistance, and barrenness resistance.

The cultivation of sweet potatoes includes ridge formation, fertilization, planting, weeding and seedling replenishment, water and fertilizer management and control of growth.

1. Ridge formation. Sweet potatoes grow better in sandy loam soils with plenty of fertilizer and water. After land preparation, ridge planting should be adopted.

2. Fertilization. Sweet potatoes need nitrogen, phosphorus and potassium elements in the growth process, more nitrogen is needed in the early stage, more potassium is needed in the middle and later stages, and when applying base fertilizer, 5000 kg of farmhouse fertilizer can be used per mu, plus a bag of compound fertilizer.

3. Planting. Spring sweet potato planting is generally carried out when the ground temperature is stable above 15, and there are methods such as flat planting and oblique planting. Flat planting is suitable for plots with good soil conditions and sufficient water and fertilizer, and the sweet potato seedlings are placed flat in the ridge, and the upper seedlings are exposed.

Inclined planting is suitable for arid, medium water and fertilizer plots, and the seedlings are planted obliquely into the ridges.

Fourth, weeding and replenishing seedlings.

Sweet potatoes are planted for 10-15 days, and the weeds are basically grown during this period, and weeding should be carried out after the seedlings are slowed. At the same time, it is necessary to observe whether there is a lack of seedlings and broken ridges in the field, and to replenish the seedlings in time. Dig up the original dead seedlings and replant another one.

Sweet potato seedling stage is mainly vegetative growth, in the top dressing of the infiltration, with 3-5 kg of urea per mu, with water.

5. Digging and missing ridges, water and fertilizer management.

When the sweet potato vine extends downward, this period is about to seal the ridge and enter the tuber setting stage, so it is necessary to prevent too much nitrogen fertilizer when fertilizing. Generally, two or three catties of urea are applied per mu, plus 10-15 catties of potassium sulfate.

Sixth, control the wang. In many sweet potato plots, the stems and leaves grow vigorously due to excessive water and fertilizer, and the tubers do not produce potatoes or the tubers are small. During the growth period, there are many ways to control the growth, such as vine lifting, vine turning, topping and chemical control.

When planting sweet potatoes, you should select healthy melons and put them in warm and moist sandy soil, wait for the melons to germinate, you can plant them in fertile and loose soil, after the plants have successfully grown seedlings, you should select healthy sweet potato seedlings and transplant them in a ventilated and sunny field.

1. Germination treatment

Before planting sweet potatoes, the first thing to do is to germinate the melons. Pick a full-bodied, non-rotten seed melon and place it in warm sandy soil and wait for it to sprout, at this point you can use a razor blade and cut it into small pieces, making sure that each piece has one or two small buds.

2. Plant

When planting sweet potatoes, you can choose fertile and loose humus soil with good drainage, and then plant the tubers of the melons evenly in the soil and cover them with fine soil. After sowing, it can provide pollution-free natural water for the seed melon, waiting for it to grow seedlings smoothly.

3. Take seedlings and cuttings

After the sweet potato grows vines more than one meter long, you can select the seedlings that grow healthy and fresh, and ensure that each seedling has six bud nodes, and then cut the seedlings in the loose and breathable soil, and water them twice a day until the seedlings resume growth.
