How to manage sweet potatoes to have high yields, and how to manage sweet potatoes to produce more

In the past, some people thought that planting sweet potatoes does not need to be fertilized, in fact, this is a wrong concept, you can think about it, the soil has no fertilizer, can sweet potatoes have yield, in the potato swelling period, it is the critical period of water demand, where the rainfall is large, it is necessary to discharge the stagnant water in time to avoid waterlogging.

In the later stage of sweet potato growth, topdressing potassium fertilizer can improve the quality and quality of sweet potato. When cracks appear on the ground in the early stage of sweet potato expansion, irrigation and application of crack fertilizer can promote root expansion, but too much fertilizer application during planting can not take root of sweet potatoes, and try not to plant too deep when transplanting, too deep is not conducive to slow down the rooting of sweet potato seedlings.

After transplanting sweet potato seedlings will grow new branches after half a month of growth, then it is necessary to start hanging vines, in the late stage of sweet potato expansion, if there is a fertilizer plot, foliar top dressing can be used to avoid premature aging, pruning every five days in summer during the growth process, and pruning every ten days in winter.

Sweet potato try not to turn over the vine, is not conducive to the expansion of sweet potato, damage the leaves, reduce the photosynthetic efficiency, affect the normal nutrient accumulation of the roots, drought can be used drip irrigation or sprinkler irrigation method watering, if it is flood irrigation, the depth should not exceed the height of the ridge 1 3, the later to reduce the amount of watering.

The sweet potato ground must be turned softer, after turning it soft, it is best to put it, organic fertilizer such as the kind of rotten leaves of the tree, and put some sheep manure or cow dung and the like, organic fertilizer is the best, the territory must be made tall, wide, high will not control the water, such a book will be very sweet, sweet potatoes can also have high yields, you can give it a try.

If you want to increase the yield of growing sweet potatoes, you must do this in order to increase the yield.

Cut off the 2-3 stems at the top of the sweet potato seedlings by planting upside down, and then cut off the petioles and leaves of the two stems above each section according to a section, keep the petioles and leaves of the two stems below, and plant them upside down on the ridge compartment to leave a petiole base to expose the ridge surface, and the seedling spacing is generally about 15 cm. Although the growth of upside-down sweet potatoes is slower than that of straight planting, due to the reversal of the direction of water absorption and organic matter absorbed by the roots transported by the conductive tissues in the stems, the conveying speed is slowed down, and a large amount of organic nutrients are accumulated in the roots, which is conducive to the expansion of potato pieces and can increase the yield by more than half.

When the sweet potato stem grows to 40-50 cm, pick the top bud in the morning in fine weather; When the branches are 30-35 cm long, continue to remove the terminal bud. This method can inhibit the growth of stems and vines, avoid nutrient consumption, promote root expansion, and increase yield by 20-30%.

Crack fertilized sweet potatoes enter the root expansion stage, and cracks will appear in the topsoil layer. At this time, 750-1000 kg of manure per mu is used, 500 grams of potassium dihydrogen phosphate (5 kg of superphosphate and 50 kg of plant ash can also be used, which are soaked and filtered with water), mixed in manure, irrigated along the cracks in the morning or evening, and filled with soil after irrigation, which can increase the yield by 20-30%.

When the sweet potato seedlings grow to 50-60 cm long, 10 ml or 20-25 ml of protein per mu can control the upper part and promote the lower part and promote the rapid growth of root tubeers, which can increase the yield by 15-20%.

In the late growth stage of sweet potato, the development of stems and leaves is slow, and the nutrients accumulated in the stems and leaves begin to transfer to the roots through photosynthesis, and the roots develop and expand rapidly. However, if the fertilizer in the field is insufficient, the rain is less, the autumn rain is waterlogged, and the management is not in place, then the stems and leaves will turn yellow and dry up in advance, photosynthesis can not continue, and the roots will gradually stop developing, resulting in an increase in small potatoes and a decrease in yield, thus affecting economic benefits.

1.Due to the long growth period of sweet potatoes, in order to prevent premature senescence of sweet potato stems and leaves, it is necessary to apply base fertilizer. The base fertilizer is mainly farmhouse fertilizer, and the fertilizer effect is long.

Farmyard fertilizer can improve soil structure, increase soil organic matter content, make the soil loose and breathable, and is very suitable for the growth and development of sweet potatoes. The use of farmyard manure can also improve the taste of sweet potatoes. Apply 2000-3000 kg of rotting farmhouse fertilizer and grass ash alkaline fertilizer per mu, which is rich in potassium and can also be used.

40 kg of grass ash is applied, 40 kg of compound fertilizer is applied at the bottom of the ridge when ridge is formed, and top dressing is 1-2 times in the middle, which can meet the fertilizer demand of the whole sweet potato growth and development period, so as to ensure the yield of sweet potato.

2.In the later stage of sweet potato growth, according to the field growth, 8-12 kg of urea, 15-20 kg of potassium sulfate or 20 kg of plant ash per mu are used to prepare a solution, and then water the root of sweet potato along the top of the ridge to supplement the split fertilizer, which can promote the expansion of sweet potato. In the later stage of sweet potato growth, in order to prevent premature aging of stems and leaves, potassium dihydrogen phosphate solution and urea solution are used per mu, and 70 kg of foliar fertilizer solution is evenly sprayed on the sweet potato stems and leaves in the afternoon throughout the field, sprayed once every 7-10 days, sprayed twice, or 15 grams of sweet potato per mu, and expanded 40-50 days before the sweet potato harvest.

3.In the middle and late stages of sweet potato growth, if the weather is dry and rainy, the soil moisture will decrease, which will also cause the stems and leaves to turn yellow in advance, which will not only affect the absorption of nutrients by sweet potato, but also lead to incomplete development of sweet potato, thereby reducing the yield. Therefore, in dry years, potato fields should be properly watered, and the soil moisture content should be 60%-70%.

It should be noted that sweet potatoes should not be watered one month before harvesting, so as not to cause excessive water absorption of potato pieces, affecting the taste and storage.

Sweet potatoes do not have a noticeable ripening period. The later the harvest, the higher the yield. It can be harvested and marketed in September at the earliest. The harvest time of sweet potatoes can be determined according to changes in market conditions for greater benefits. However, sweet potatoes are afraid of cold, and the latest harvest should be in the late frost period.

"In the later stage of sweet potato growth, it is necessary to chase the "two fertilizers" (irrigation crack fertilizer and foliar fertilizer) When sweet potato enters the stage of underground stem expansion and development in the late growth stage, the nutrients it needs most at this time are potassium fertilizer, because potassium fertilizer can improve the robustness and resistance to diseases and insect pests of sweet potato, enhance the transport capacity of nutrients from sweet potato plants to underground stems and accumulate reserves, and promote the rapid expansion and weight gain of underground stems; At the same time, a small amount of phosphate fertilizer and nitrogen fertilizer are also needed, because phosphate fertilizer can maintain the root system of sweet potato, promote sweet potato thickening and enlargement, prevent the problem of small tendons in sweet potato, nitrogen fertilizer can prolong the life of green leaves, enhance the ability of leaf photosynthesis to produce nutrients, and prevent sweet potato from reducing yield due to premature senescence and yellow wilting of stems and leaves.

When sweet potatoes enter the late stage of growth, when the underground stems are enlarged and developed, the nutrients it needs most at this time are potassium fertilizer, because potassium fertilizer can improve the robustness of sweet potatoes.

Chasing sweet potato "crack fertilizer" Normally, sweet potato crack fertilizer is generally the most suitable to be applied around the end of August (the period when underground stems are concentrated and expanded) to promote high yield and increase income.

Sweet potatoes are a food that we all often eat in our daily life, rich in a variety of nutrients, and have anti-aging and anti-cancer functions.

The efficiency of planting sweet potatoes is higher, so how can the management of sweet potatoes be high? The following hot agricultural investment network will introduce you to the sweet potato field management technology.

How to manage the management of sweet potatoes After planting high-yield sweet potatoes, it is necessary to check the seedlings in time and replenish the seedlings, and carry out cultivation and weeding, which is the link of high yield of sweet potatoes and provides guarantee for the later growth of sweet potatoes.

In the middle of the growth of red simple potato tuber, that is, the tuber expansion stage, this period is the peak period of sweet potato stem and leaf growth, and the tuber thickens and expands rapidly.

The middle growth period of spring sweet potatoes is generally 60 to 90 days after planting, and the middle growth period of summer and autumn sweet potatoes is generally 40 to 70 days after planting.

During this period, we should pay attention to drought prevention and drainage, lift seedlings and break roots, but pay attention not to turn the seedlings, for the sweet potatoes that appear to grow vigorously to control the prosperity in time, you can use 15% paclobutrazol 50 70 grams per mu, spray 50 kg of water, usually spray 2 3 times to achieve the ideal effect of controlling the prosperity.

At the same time, it is necessary to chase potato fertilizer, and apply 10 kg of potassium sulfate fertilizer or 100 150 kg of plant ash per mu.

In the later stage of sweet potato growth, it is necessary to pay attention to the supplementary application of crack fertilizer (also called bulking fertilizer).

15 kg of superphosphate and 5 kg of potassium sulfate can be applied per mu, and the irrigation effect is better after taking 100 kg of water; In addition, it is necessary to pay attention to foliar spraying, with urea dilution or 2% 3% superphosphate solution, can also be used with 5% plant ash water or potassium dihydrogen phosphate solution and 1% urea solution for foliar spraying, 7 10 days spray 1 time, spray 2 3 times.

Field management techniques for sweet potatoes in high temperature season1In the high temperature season, sweet potatoes grow relatively quickly, so it is necessary to spray the nutrient solution for sweet potatoes in time to promote flowering to ensure the growth of sweet potato roots and promote the expansion of sweet potatoes. Infiltrate the Mausoleum.

2.After the summer is the expansion period of sweet potato, which is an important moment for sweet potato planting, we must strengthen fertilizer management, properly spray fertilizer for strong fruits, improve the nutrient capacity and expansion vitality of red rope absorption, and promote better and faster growth of sweet potato.

3.In the later stage of sweet potato growth, with the weakening of growth ability, it is necessary to spray phosphorus and potassium fertilizer on the page, generally spraying once in 10-15 days, and practicing spraying 2-3 times to ensure the nutrients needed for the growth of sweet potatoes to improve the yield and quality of sweet potatoes.

The above is for you to introduce the management of sweet potatoes how to manage high yield and sweet potato field management technology, if you want to know more about the agricultural market, you can follow: WeChat***: huobao3456tv to learn more, you can also leave a message to reply to the industry information you want to know after attention.

The management of sweet potatoes should be timely replenished seedlings, reasonable top dressing, control of growth, and spraying leaf fertilizer in the later stage of growth. In addition, when planting sweet potatoes, it is necessary to choose those high-yield varieties, which is also the basis for making sweet potatoes high-yielding.

Timely replenishment of seedlings and weeding

The management of the seedling period after the planting of sweet potatoes is extremely important, after planting sweet potatoes, we must check in time to see if the seedlings are neat, if we find that the seedlings are uneven, we must replenish the seedlings in time, and the seedlings must be carried out in the morning or in the evening, avoid direct sunlight, and water the seedlings in time after replenishment, so that the new seedlings can survive as soon as possible.

Reasonable topdressing and weeding

If you want to make your own management of sweet potatoes with high yield, you must plant sweet potatoes, loosen the soil and clean up the weeds in the field in time for 1 or 2 months, avoid weeds and sweet potatoes competing for nutrients, and spray some weeding drugs in the soil after cultivating, in addition to the top dressing in time within 30 days after the sweet potato planting, and then plant sweet potatoes, the previous 30 days should also be applied in the soil with foot fertilizer, only sufficient fertilizer can promote the normal growth of sweet potatoes in order to make sweet potatoes bear more fruits so that it can achieve high yield.

Control the growth can be high-yielding

Sweet potato is a plant with strong vitality, this plant grows particularly fast after planting, and is prone to soil, so only by controlling the soil and pinching the top in time can it have high yields. After the sweet potato has passed the seedling stage, it is necessary to spray 15% paclobutrazol wetting powder in time, this drug has no toxicity, but after the use of medicine, it can control the growth of sweet potato, so that its roots can absorb more nutrients, and will make the sweet potato high yield.

Timely spraying of foliar fertilizer can lead to high yields

After the sweet potato enters the late stage of growth, its roots will absorb fertilizer much weaker, so it is necessary to spray foliar fertilizer in time to feed the sweet potato to supplement nutrition. When spraying foliar fertilizer, urea solution can be sprayed, calcium phosphate solution can also be sprayed, and some sweet potato bulking pigment can also be sprayed, these drugs can be sprayed every 7 10 days, and the size of sweet potatoes can be significantly increased after spraying, which can meet the needs of people with high yield.

These are the scientific methods for managing sweet potatoes, these methods can be used together to make sweet potatoes high-yielding, and sweet potatoes are particularly drought tolerant, so they should not be watered too much during the management period, otherwise it will affect its normal growth and will also affect its yield.

Regular fertilization and watering to ensure adequate nutrition; Remove the excess branches; Don't plant too intensively, as dense will result in sweet potatoes being too small and yielding low.

To increase the yield of sweet potatoes, it should be managed as follows:1Before planting, cut off 2-3 stems from the sweet potato seedlings to be planted, and cut off the petioles and leaves of the stems.

2.When the branches are 30-35 cm long, continue to remove the terminal buds. 3.

Use inorganic nutrients, such as chicken manure.

Light application of nitrogen fertilizer. Too much nitrogen fertilizer will cause the stems and leaves to grow wildly, consume a lot of nutrients, and when the fruit is expanded in the later stage, the nutrient supply will be insufficient, resulting in small fruit and reduced yield.

To have a high yield of sweet potatoes, you first need to carefully choose where you grow them。It can be said that the sweetness of sweet potatoes is not high, which is closely related to the soil environment in which it is grown. In general, sweet potatoes are best grown in sandy soils.

The planting environment has good water permeability and air permeability. It is suitable for the growth of sweet potatoes, so sweet potatoes are also sweeter. Sweet potatoes are not suitable for growing in highly cohesive soils.

Not only do they have a low yield, but they also have a mediocre taste and poor sweetness.

Cars need to prepare the land and fertilize. It is best to use fermented farmhouse fertilizer for planting sweet potato-based fertilizer in rural areas, such as chicken manure, pig manure, duck manure, etc. It is best to mix some plant ash to prevent the introduction of some pests and diseases, such as plant ash.

Sweet potatoes are the favorite fertilizer that can make sweet potato chunks grow faster and improve the taste of the sweet potatoes themselves. As the saying goes, sweet potatoes are a pile of ashes, and sweet potatoes form a lot. To promote the expansion and yield of sweet potato rhizomes, more than 4,500 kg of well-rotted organic fertilizer should be applied per mu, and some balanced compound fertilizers should also be applied.

In addition, it is not recommended to turn the vine to control sweet potatoes. After the sweet potato garden is closed, it is the season of high temperature and rain, which is easy to cause exuberance, so it is necessary to control the exuberance. Sweet potatoes are known to have a strong ability to grow.

If they don't turn over, secondary roots will grow in the stem nodes, and these fibrous roots will absorb nutrients from the soil to feed the sweet potato seedlings, which will eventually lead to the sweet potato to thrive. The place where these fibrous roots grow is actually equivalent to a sweet potato, and some even produce sweet potatoes, but these sweet potatoes are not economical at all, and they will consume too much nutrients in the soil, and eventually lead to the development of sweet potato taproots.

It is important to know that sweet potatoes, like corn and peanuts, are high-yielding crops, and for high-yield crops, topdressing must be adequate. Sufficient basal fertilizer can not only promote the growth and development of crops, but also better increase the nutrient use efficiency of crops. Absorb and improve crop yields, but sweet potatoes must be paid attention to when topdressing basal fertilizer, and pay attention to topdressing organic fertilizer.

Top application of organic fertilizer not only provides long-term nutrients**, but also improves soil aggregate structure, loosens soil, and improves soil permeability and water retention.
