Hello, can I ask you some questions about growing sweet potatoes?

This is okay, I am relatively proficient in the problem of planting sweet potatoes, if you have any questions, you can ask me directly.

If you want to grow sweet potatoes, you can ask some experienced farmers or technicians who have some skills.

This kind of thing is very difficult to say clearly here, because we come back to the problem that it is a little bit impossible to give you a long speech, you can go online and collect some of it. In fact, there is a lot of information on the Internet, that is, the Internet.

1. Land preparation. Land preparation should be carried out on a sunny day, and the soil should be broken and finely beaten. After leveling, the fertilizer strip is applied to the bottom of the ridge, the ridge distance is 80 cm, and the ridge height is about 20 cm. Special organic compound fertilizer can be used for fertilizer.

2. Seedlings. Choose seed potatoes with typical characteristics of this variety, free of diseases and pests, and 100-250 grams of potato pieces. The density of the planting is about 3 cm apart between the tubers, and the seed potatoes are covered with soil after the rowing, with a thickness of 2-3 cm and not more than 5 cm, so as not to affect the emergence of seedlings.

3. Planting. When the seedlings are 20-25 cm long and have 6-8 complete leaves, they can be cut and planted in the field. When planting, the 4 nodes are inserted horizontally or obliquely into the soil, and the two leaves are exposed to the ground when the drought occurs, and the rest of the leaves are buried in the soil, so as to facilitate the survival of potato seedlings and the dispersion of potatoes evenly, improve the commodity rate and yield, and the planting density is 4000 plants 667 square meters, and the plant spacing is 20 cm.

4. Field management.

Sweet potato has strong drought tolerance adaptability, and the soil water holding capacity should be controlled at 60-70%, and management should be strengthened in rainy days, and attention should be paid to reducing water accumulation in the field. About 15 days after planting, the seedling fertilizer was applied in combination with the first tillage. 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.

5. Pest control.

The main diseases are virus disease, black spot disease, purple striped feather disease; The main insect pests are Spodoptera litura, sweet potato leaf beetle. Timely symptomatic control of pests and diseases.

Hello, if you plant sweet potatoes, this is very simple, as long as the land is fertilized, and then weeding regularly, it will be planted very well.

Hello, can I ask you some questions about planting square bamboo? Of course, the number of planting squares is very easy to cultivate, and its growth or salutation is very high.

If you grow sweet potatoes, in fact, every place is different, for example, they are planted in the south and north, and then the time is also different.

<> "On this issue, many people will definitely directly say that they choose excellent varieties for planting, etc., I think it is irresponsible for this, why? Because even if there is more than one excellent variety, there is still a greater or lesser difference in yield between different varieties. Choose well-rotted farmhouse fertilizer, generally apply 2500 4000 kg of well-rotted manure per mu of sweet potato field.

20 kg of ammonium carbonate, 50 kg of superphosphate and 25 kg of potassium sulfate are applied. Make sure that the sweet potatoes have sufficient nutrients so that the roots are deeply rooted.

It can be said that sweet potatoes are the highest yield per mu grain crops I have ever seen, and there is no one. As early as the 80s of the last century, there was a typical case of 10,000 catties per mu, but sweet potatoes laid eggs (directly in the spring live broadcast of small sweet potatoes, in addition to providing some seedlings, we belong to the southwest of Sichuan, hilly and mountainous areas, a variety of agricultural products, rice, corn, wheat, rape, peanuts, soybeans, sweet potatoes, etc. Now to develop into Sichuan Province millet pepper planting base), a few years ago sweet potato is the main agricultural product, but also high ridge cultivation of sweet potato, can increase the area of sweet potato roots by sunlight and heat energy, promote the expansion of sweet potato roots and roots, while reducing sweet potato in the root growth and expansion of soil resistance, increase the root soil permeability and light transmittance, in the sweet potato varieties are many, from the color point of view there are white hearts, yellow hearts, red hearts, purple hearts.

There are also many different varieties of sweet potatoes of each color. Each harvest, adaptability and taste are also different. Cover the sweet potato seedlings with mud on the roots, and then wait for the sweet potato seedlings to grow to three feet long, turn the sweet potato seedlings in the opposite direction, and pinch off the main vine of the sweet potato seedlings, so that the sweet potato seedlings are not allowed to grow vines, so that it can rise sweet potatoes and bear more, in fact, sweet potatoes want it to rise in our sweet potato varieties The yield of sweet potato varieties is like this, yellow sweet potatoes white sweet potatoes watermelon sweet potatoes purple potatoes, but the level of ** is also the opposite.

Therefore, if you want to simply choose high yield, you can choose yellow sweet potatoes and white sweet potatoes.

This problem, in fact, when we plant sweet potatoes, we are full of land to be planted and will not go to the count, how much is needed, I estimated, one acre is so big, the loose point of the plant is forty or fifty catties, and the heavy dense point is sixty or seventy catties (I think about the amount of the back basket before), the vines are originally growing everywhere, and there is nothing to plant loosely, and if you pick the mother species, try to pick the kind that has no disease, for example, you can't want the kind of black spots, and the sweet potatoes that grow out are more delicious, and they grow more smoothly.

There are about 300 kinds of needed, so when choosing, you must choose a relatively high quality, and the production volume is relatively high, and the quality is generally higher.

Select seed potatoes to choose high-yield and high-quality "868" sweet potatoes in other places as the mother seed, each mu of field needs 2 square meters of seedbed for seedling, 200 seed potatoes, about 50 kg.

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.

1. The temperature is suitable. Sweet potato is a thermophilic crop, poor cold tolerance, suitable for growth temperature between 22-30 degrees, will stop growing when it is lower than 15 degrees, plant death when it is lower than 8 degrees, and different growth stages have different temperature requirements, such as germination temperature between 18-22 degrees.

2. Abundant light. Sweet potato is a short-day herbaceous plant, during the planting period like abundant light, but not shade tolerant, to ensure 8-10 hours of light a day, can promote the plant to photosynthesize, is conducive to flowering and root growth, sufficient light time can also accumulate enough nutrients.

3. Soil requirements. The root growth of sweet potato is relatively developed, has a strong ability to absorb fertilizer, has a certain adaptability to the soil, it is best to choose a neutral soil with soft, deep soil and good drainage and air permeability when planting, remove weeds when ploughing, and apply special organic compound fertilizer to increase fertility.

4. Maintain humidity. Although sweet potato drought tolerance is stronger, but during the growth period of the water demand will be increased, to maintain the soil moisture is conducive to crop growth, in the seedling stage and stem and leaf stage, the soil moisture can not be less than 60%, the humidity is too low seedlings grow slowly, the root expansion of the humidity is kept at 70%, can speed up the expansion rate.

The first is sweet potato base fertilizer, using farmhouse fertilizer, 3500 kg, 66 kg of ammonia sulfate, 80 kg of superphosphate, and 53 kg of potassium sulfate.

Second, in the plot with good soil quality, you can use large ridges to plant sweet potatoes in double rows, sweet potato ridge spacing is 100 cm, ridge height is 35 cm, plant spacing is controlled at about 30 cm, and 4000 seedlings are planted in one acre.

Sweet potato planting. Third, sweet potatoes can be planted with carbendazim for ten minutes, and the seedlings can be directly planted obliquely on the ridge, and two rows can be planted in one cage.

Fourth, sweet potatoes began to chase urea half a month after planting, ten kilograms per acre, at least 15 cm from the roots, the second time in the soil cracks when chasing 25 kilograms of calcium phosphate and 15 kilograms of potassium sulfate, 20 days before harvesting, the sweet potato foliar surface was sprayed with potassium dihydrogen phosphate again, and at the same time sprayed with bulking hormone.

First, choose the soil for sweet potato planting If you want to have a high yield, you should first work the planting soil, choose a flat and open plot, which requires sunlight, easy drainage, and leeward. The soil planted is required to be loose and uniform, the soil layer is deep and not compacted, and it is fertile and rich in humus.

Second, the seedling sweet potato can be directly purchased with high yield, good growth, no pests and diseases of the seedlings to plant, you can also choose your own seed potatoes to raise seedlings, seed potatoes require no frost damage, no insect pests, uniform size, moderate size, sterilization in advance, and then planted into the soil to raise seedlings.

3. Tidy up the soil, deep plough and dry the soil, apply well-rotted high-quality farm fertilizer, and also need to mix with chemical fertilizers such as diammonium phosphate, urea, and potassium sulfate. To make ridges on the soil, it is generally a high ridge double row dense planting, the ridge height is about 20 25 cm, the ridge width is 60 80 cm, and the ridge spacing is 15 20 cm.

Fourth, transplanting planting will plant seedlings into the soil, cover the roots with soil, lay mulch, increase the surface temperature, but also retain water and fertilizer, which is conducive to the rapid growth of potato seedlings.

5. Management methods: After a few days of planting, you can check the seedlings and replenish the seedlings, cultivate and weed in time, and avoid competing for nutrients with the sweet potato seedlings. In order to achieve high yields, attention should be paid to top dressing, mainly nitrogen and phosphorus and potassium fertilizers, and regular irrigation is also required during the growth stage.

6. The harvest time is usually from late September to mid-to-late October, and the sweet potatoes can be harvested.

First of all, we must pay attention to reasonable field management, in addition to sweet potatoes are very afraid of low temperatures, if after being damaged by low temperature frost, sweet potatoes will gradually ferment and deteriorate very much to affect the yield of sweet potatoes, in addition to being careful when turning over the vines, do not hurt the stems and leaves, improper fertilization will also lead to a decrease in the quality and yield of planted sweet potatoes.
