How to grow sweet potatoes? How long does it take to plant to get a harvest 10

Generally, if there are no seedlings, find a sprouted sweet potato, pull the sprout and cut off a piece of sweet potato below, plant it in the soil, plant it in spring and harvest it in autumn.

In spring, sweet potatoes should be planted as soon as possible after the final frost. Autumn harvest should be harvested before and after frost, when the root wither, leaf yellow, and bulb are fully mature.

The planting of sweet potatoes starts from soil conditions, planting methods, maintenance and management.

1. Soil conditions.

When planting sweet potatoes, it is necessary to choose a deep and well-drained soil for them, and the pH of the soil should be between, and a mixture of nitrogen, phosphate and potassium fertilizers should be applied to the soil.

2. Planting method.

When planting sweet potatoes, you need to choose healthy and disease-free seed potatoes with good growth, then cut the seed potatoes into about 170 grams of pieces, and then you can spread the potato pieces on the soil surface, and cover 2-3 cm of soil above, and finally water them once to make the sweet potatoes germinate quickly.

3. Maintenance management.

When maintaining sweet potatoes, it is necessary to apply a rotten farmhouse fertilizer or urea to the plants after 15 days of planting to promote the vigorous growth of sweet potatoes, and during the growth of sweet potatoes, it is necessary to cut off the branches and leaves that grow too much, so as not to lose excess nutrients, promote the growth of sweet potato tubers, and increase its yield.

Types of sweet potatoes

1. Purple sweet potato.

Purple sweet potato is native to Central America, its celery peel and potato flesh are dark purple, and the purple sweet potato will flow out of the lilac liquid, can be used as a natural pigment, when cultivating purple sweet potato, it needs to be planted in a warm and sunny environment in Wensun Heyan, and the soil moisture content is kept at about 70%.

2. Red sweet potato.

The skin of the red sweet potato is light yellow, the flesh is light red, it has a very high nutritional value, it is the most widely sold sweet potato on the market, when breeding the red sweet potato, it is necessary to provide it with sandy loam soil with good drainage, and apply well-rotted organic fertilizer in the soil to provide the nutrients needed for the growth of the red sweet potato.

3. Yellow heart potato.

The peel and flesh of the yellow heart potato are light yellow, its taste is sweet and soft and glutinous, when breeding the yellow heart potato, it is necessary to sow it in March and April in the spring of each year, because the light time at this time is longer, which is conducive to the growth of the yellow heart potato, and in the rainy season, it is necessary to discharge the water in the soil for the yellow heart potato.

1. Select sweet potatoes to plant.

Sweet potatoes should be planted to choose neither old nor young, so that it is easy to live.

2. Loosen the soil. Generally, everything needs to be loosened, which is conducive to the survival rate. Growing sweet potatoes needs to be piled up a little higher.

3. Planting. Dig a pit in the loose soil, and the gap should not be too large. Then plant the sweet potatoes in the pit, and put the stems down a little bit to avoid death from the sun.

4. Fill the pit. Put the soil in the pit with a hoe until it is filled, and then step on the pit with your feet so that the soil is closely connected with the stem of the plant.

5. Watering. Generally, the seeds need to be watered after planting, and the sweet potatoes need to be watered the next morning after watering.

Isn't it very simple, sweet potatoes don't need to be managed much, just need to be watered occasionally, and he can grow a lot of sweet potatoes.

How to grow sweet potatoes:

1. Apply plantar fertilizer. The base fertilizer should be based on organic fertilizer and phosphorus and potassium fertilizer, and nitrogen fertilizer should be applied less or no nitrogen fertilizer in general.

2. Ridge planting. Because sweet potato is a short-day crop, the greater the temperature difference between day and night, the faster the tuber swells. Ridge formation can expand the ventilation and light transmission area, artificially form a temperature difference between day and night, and accelerate the expansion rate of tuber roots.

3. Increase density. Moderate dense planting is the guarantee of high yield of sweet potato. Detoxified sweet potato has the characteristics of neat growth, rapid root expansion, and no empty plants, which is very beneficial to improving density.

Generally, the suitable density of sweet potatoes with a yield of more than 10,000 catties per mu is 4,500-5,000 mu for spring planting and 5,000-6,000 mu for summer planting.

4. Do a good job of chemical weeding. After the sweet potato seedlings are planted, they should be evenly sprayed with acetochlor (kilograms per mu) in time; Or in front of the three true leaves of the weeds, spray and catch them in time (40-80 grams per mu), which can generally ensure that the whole growth cycle does not need to be weeded.

5. Do a good job in chemical control. The seedlings of detoxified sweet potato are growing vigorously, and it is very important to do a good job in chemical control to improve yield. Generally, when the sweet potato seedlings grow to 45 cm, 50 kg of paclobutrazol solution of 200 mg kg can be sprayed per mu.

6. It is strictly forbidden to turn over vines. Sweet potato vine turning is a kind of fruitless yield reduction measure, generally reducing the yield by more than 10%. The photosynthetic area is destroyed after vine turning, which reduces the accumulation of photosynthetic products and reduces the yield of underground roots, so vine turning should be strictly prohibited.

Spring sweet potato high-yield cultivation technology Sweet potato is a root crop, which has the characteristics of high yield, stable yield, wide adaptability, strong stress resistance, rich nutrition and wide use. In the adjustment of the planting structure, it has become a hot crop.

First, it is the selection of varieties, the general yield of black potatoes in land preparation and ridge building is lower than that of local sweet potato varieties, and the yield of fresh potatoes per mu is about 2,500 kg. I planted Black Potato No. 1, which has a higher yield than Japanese Kawayama purple, and the yield per mu is 500 kg higher than that of Kawayama purple, which is currently the highest yield of black potato. In the spring around April to the potato field to carry out deep turning, so that it is frozen and loose soil, into the end of April, 50 kg of sweet potato special fertilizer per mu, potassium sulfate 100 ?

125 kg and a deep turn again, then creating a ridge with a width of 30 cm at the top, 45 cm at the bottom and 25 cm in height. 2. Seedlings and planting began to raise seedlings on March 20, select the seed potatoes in the shape of the potatoes, and place the seed potatoes in the prepared field in order according to the flat way. Keep a distance of 2 cm between the seed potatoes, then water them enough, cover the field with a thickness of 3 cm, and cover them with plastic sheeting.

In the middle of May, select stout seedlings, transplant and plant according to the plant spacing of 40 cm, and water them when planting to ensure that the whole seedlings survive. And the ridge soil is broken up, so that the ridge surface is flat and the soil in the ridge is loose. After planting, large water irrigates the field along the ridges, which is conducive to the survival and normal growth and development of potato seedlings.

3. Management After transplanting, the temperature is getting higher and higher, and the weeds in the field will grow vigorously. Timely detection and timely removal, when the vines are overgrown on the ground, there will be no grass. If there is no rain for a long time, it is necessary to irrigate in time, and after the vine grows 66 6 cm, it is necessary to spray this sweet potato bulking hormone every 10 days to promote the rapid expansion of its rhizomes and improve the yield.

The temperature entering June is ideal for tuber bulking, and foliar spraying of bulking pigment is important. If summer potato cultivation is carried out, the base fertilizer per mu is the same. Fourth, the harvest of sweet potatoes is generally before the frost period.

The potato has a special color, special value and market timely harvest is the key to increase the output value. In mid-September, it can be partially harvested, and the tubers reach oWhen the weight is 25 kg, the potatoes are picked from the side of the ridge, and the large ones are taken out of the market, and the small ones are left to continue to grow.

All the potatoes can be harvested before the month of LOL, and the mashed potatoes will be washed and packed for marketing.

You can buy some sweet potato seedlings, (usually sold in spring) and plant them directly! Very simple.

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.
