How to apply base fertilizer to sweet potatoes? What is the fertilization experience of old farmers?

There are many starch processing plants and vermicelli processing factories in the three powder bases, and the demand for sweet potatoes is very large, and basically there will be no situation where sweet potatoes cannot be sold. Sweet potatoes are drought tolerant, barren tolerant, high yield, simple management, and relatively high planting efficiency, so there are still many farmers who plant sweet potatoes. In the past difficult years, farmers spent most of the year eating sweet potatoes to satisfy their hunger, and even the snacks that children ate during the New Year were made of sweet potatoes.

In the process of planting sweet potatoes for a long time, farmers are also quite familiar with them.

And also summed up in addition to many experiences. The base fertilizer of sweet potato is mainly soil miscellaneous fertilizer and potassium fertilizer, grass ash. Before the sowing period, sufficient soil miscellaneous fertilizer is sprinkled in the sweet potato cultivation field, and then deep ploughing and turning the soil are carried out to allow the soil miscellaneous fertilizer to penetrate tightly with the soil.

When planting sweet potatoes, prepare the land for high furrows, and choose sweet potato cuttings for planting after rain or on cloudy days. For example, sweet potatoes are underground clumping crops, and it is inconvenient and easy to damage the rhizomes in the later stage, so it is mainly to apply sweet potatoes before ridge formation to form a large pile."

The "ash" here generally refers to the grass ash in the countryside, the ash at the bottom of the kang two, generally in the northwest countryside in the "ash at the bottom of the kang" is more, because in the winter the countryside will be filled with kang, so the whole winter will save a lot of "kang fertilizer". Only reasonable fertilization can increase yield and improve quality. So, what fertilizers do you need to use before sweet potato ridges?

How to fertilize the sweet potato rhizome for absorption and growth? Sweet potatoes are grown in the village, and in general, they are taken from the manure of cows, pigs, chickens, ducks, rabbits, geese, and other poultry. <>

After fermentation and rotting, it is used to grow sweet potatoes and peanuts and make a base. Or it is made by shoveling turf on wasteland and planting land, mixing and mixing soil and burning it, which is called "fire ash". Nowadays, with the continuous improvement of people's living standards, sweet potatoes not only did not withdraw from people's sight, but turned into a variety of delicacies, and even many places have been planted in large areas, high-quality and high-yield sweet potatoes are the pursuit of growers, as the saying goes, "crops are a flower, all rely on fertilizer".

According to the size and area of sweet potato seedlings, reasonable fertilization, pay attention to the amount of fertilizer, and pay attention to the selection of fertilizer components. To fertilize the roots, you must water them, and the amount must be controlled evenly, the absorption of sweet potatoes must be ensured, the soil must be loosened, and so on.

When the sweet potatoes are planted and are already growing well, they need to be fertilized. When fertilizing, you need to get rid of weeds, turn over the vines, remove the excess vines of the sweet potato, and keep one or two main vines.

In order to promote good roots, fast greening, early tillering, the formation of enough strong tillers, to achieve high yield of growth, to scientific water and fertilizer management as the center. In order to meet the physiological water demand requirements of rice, water should be used to regulate the growth and development of rice plants, and the water management at the tillering stage should achieve "inch water returning to green", "thin water tillering" and "timely tillering control".

2000 kg of livestock manure, add 150 kg of plant ash, stir evenly, after patting, cover the fermentation with plastic film for about 30 days, sprinkle into the sweet potato field, and then level the land, raise the high wall, when the sweet potato is planted, then apply 15 kg of nitrogen, phosphorus and potassium compound fertilizer per mu, the growth and development period of sweet potato is relatively long, spring sweet potato needs 150-180 days, wheat stubble sweet potato needs 120-140 days, sweet potato is a particularly potassium-loving crop, in the production process needs the most potassium, nitrogen fertilizer is the second, phosphate fertilizer is the least, The fertilization principle of sweet potatoes is to control nitrogen, stabilize phosphorus, and increase the planting of sweet potatoes in the countryside in the past. When growing sweet potatoes, base fertilizer is also essential. After all, sweet potatoes.

.The comprehensive fertilizer of organic fertilizer and compound fertilizer is the best for the base fertilizer. The amount of base fertilizer applied for planting sweet potatoes accounts for 80% of the total fertilizer requirements during the whole sweet potato growth period, so good base fertilizer is used for the growth of sweet potatoes.

Quality. Good and bad. The level of production plays a key role.

Choose farmhouse fertilizer, such as a mixture of leaves and weeds, as a fertilizer at the bottom of sweet potatoes, laying about 3 cm is the most suitable, or practical animal manure can also be, farmhouse fertilizer, good fertilizer efficiency, no chemical pollution, is the first choice for farmer's fertilizer Sweet potato is a nutritious planting crop, and the bottom fertilizer and appropriate amount of top dressing are the main ones in the growth process. The base fertilizer of sweet potato is mainly soil miscellaneous fertilizer and potassium fertilizer, grass ash. Before the sowing period, the sufficient soil miscellaneous fertilizer is sprinkled in the sweet potato cultivation field, and then deep ploughing and turning the soil, so that the soil miscellaneous fertilizer is better than the recommended use of phosphate fertilizer in this fertilizer, because the effect of phosphate fertilizer can loosen the soil, which is conducive to the expansion of sweet potato tubers, so as to achieve the effect of high yield of sweet potatoes.

In the daily management, the compartment takes straw to burn the plant ash, if the compartment really sprinkles the plant ash on the leaves and soil in case of rain, and the soil is sprayed with plant ash water on a sunny day, and the leaves are sprayed at the same time, which plays a role in preventing and controlling various pests and diseases on the ground and supplementing the elements.

Generally speaking, planting sweet potatoes requires the use of bottom fertilizer. The base fertilizer is relatively simple, we can choose some farmhouse fertilizer and plant ash to use, if possible, you can also add superphosphate and calcium bicarbonate, so that the effect will be better.

Absolutely. The base fertilizer should be selected according to the growth of sweet potatoes, and phosphate and nitrogen fertilizers should also be selected.

Yes, at this time, according to the different growth conditions of sweet potatoes, as well as the varieties of sweet potatoes, to choose the right compost or organic fertilizer.

We definitely need base fertilizer, and we should choose the kind that is of better quality and has a lot of materials to prevent pests and diseases.

In order to have a higher yield, of course, it is necessary to use a base fertilizer, and it is better to choose a completely decomposed organic fertilizer. Because this organic fertilizer is more nutritionally balanced.

Of course, you need a base fertilizer. Personally, I think farmhouse fertilizer is the best, but this needs to be supplemented in advance, and then wait for the fertilizer to decompose almost before planting.

It is necessary to use base fertilizer, so that the survival rate is relatively high, the nutrition is richer, and the fertile base fertilizer is selected.

Planting sweet potatoes must be fertilized, when planting sweet potatoes can be applied with chemical fertilizer, you can also use household manure, manure is rich in nutrients, and sweet potato absorption is also very good, when the sweet potato vines are luxuriant, you must turn the sweet potato vines, so that the sweet potatoes will grow big and many, and the yield is really been.

Fertilize it when it's just planted, and then wait for it to grow seedlings. Usually you should water the sweet potato more and add more organic fertilizer to it, so that the sweet potatoes grown will be big and abundant.

If you want sweet potatoes to grow well, you need to be careful and careful in fertilization, and if you do it properly, you can harvest a lot. Generally, there are two ways to fertilize, one is to spray fertilizer directly on the foliage, and the other is to directly pour fertilizer into the soil, the fertilizer preferred by this plant is potassium fertilizer, so we usually use fertilizer containing nitrogen, phosphorus and potassium to maintain.

Apply basal fertilizer to sweet potatoes, or farm fertilizer. If the sweet potato grows well, you can chase less fertilizer, or not chase non, if the sweet potato does not grow well, this time you should top the fertilizer in time, because this can provide it with sufficient nutrition. Sweet potatoes are generally planted for about a month to reach the peak growing season, and topdressing should be carried out in time at this time.

Then wait for more than two months, sweet potatoes into the late stage of growth, this time should also be timely top dressing, this time can also be with an appropriate amount of water, so that the sweet potato can be better absorbed.

When fertilizing, you should pay attention to the time of fertilization, and it is more appropriate to choose this time period in the morning.

What are the key points and precautions for fertilizing sweet potatoes? How to fertilize to achieve high yields?

The fertilization of sweet potatoes needs to pay attention to different stages, different total amounts, and different types of chemical fertilizers. Since sometimes, sweet potatoes belong to the long leaves, at this time, if it can be without so many chemical fertilizers. However, in the case of tuber-setting conditions, this requires enough fertilizer and water to ensure an increased yield.

Therefore, how to fertilize, in fact, there is a very big focus. When the seedlings are in the early failure stage, it is necessary to pay attention to enough chemical fertilizers so that the leaves of sweet potatoes can grow well. So that the seedlings can be abundant.

But in the middle stage, it is necessary to manipulate the length of the seedlings, so that they cannot be patronized all the time to bear the leaves, and do not produce sweet potatoes. At this time, due to the lush branches and leaves of sweet potatoes, you should also pay attention to fertilizer.

In the later stages, the leaves of the sweet potato will turn from emerald green to light yellow. At this time, it is necessary to pay attention not to let sweet potatoes enter the phenomenon of senescence. If it is senile, it will affect the potato set, and the size of the sweet potato will also be harmed.

However, one point that must be made here is that one month before the sweet potatoes are to be picked up, do not fill them with water, otherwise, it will be a great inconvenience for the future storage of sweet potatoes. We should also pay attention to the selection of chemical fertilizers. At present, in many rural areas, only organic fertilizers are used.

This is not enough. Over time, the soil layer will clump and lose its fertility. For cultivated plants such as sweet potatoes, which must be loosened soil, it must be a very big damage.

Choosing organic fertilizer and organic fertilizer mixed application will be of great help to the rise of sweet potatoes. Organic fertilizer is the fertilizer of human and animal manure and grass ash. This kind of chemical fertilizer is carried out according to the ratio of different types of plums to dry holes.

When fertilizing, it also depends on the growth of seedlings. The form of fertilization is also different for seedlings at different stages. When the seedlings are planted three to five days later, a small hole of 10 cm can be inserted at the root of the seedling, and the urea solution can be poured into the soil covered.

This behavior is conducive to ensuring the healthy growth of seedlings. Until the seedlings grow and set potatoes, fertilizer can be added. At this moment, the fertilizer can be applied along the gap where the potato roots swell.

The selected chemical fertilizer, after fertilization, should be watered once. Push chemical fertilizers to work. By the time the tubers are formed, the amplitude and frequency of fertilization can be increased.

Because of the fertilizer at this time, the absorption of sweet potatoes is more limited. Therefore, fertilization can also be applied outside the roots. However, it is important to make a point here.

If you apply organic fertilizer. These farmhouse fertilizers can only be applied after they are fully alcoholized.

When fertilizing, it should be combined with spring watering of the rolling source; After the swelling period, attention should be paid to controlling the application of nitrogen fertilizer; Before planting sweet potatoes, it is necessary to pay attention to the application of sufficient base fertilizer and simple preparation, mainly rotting farmhouse fertilizer, and the appropriate amount of chemical fertilizer can be used.

It is necessary to apply more phosphorus and potassium fertilizers to sweet potatoes, spray fertilizer on their foliage, ensure that the bottom fertilizer of sweet potato fields is sufficient, and prevent and control pests and diseases in time; Fertilization should be based on the growth of sweet potatoes, and the appropriate fertilizer and slag should be continuously selected, and a small amount of top dressing should be carried out many times.

1. Applying sufficient basal fertilizer is a fundamental measure to meet the long growth period and large fertilizer demand of sweet potato.

1. When turning the soil, apply about 5,000 kg of rotten farmhouse fertilizer per mu, and at the same time apply about 30 kg of phosphate fertilizer and about 100 kg of plant ash. Rotted farmhouse manure such as chicken manure, cow manure, sheep manure and other soil miscellaneous fertilizers.

2. The basal fertilizer can be combined with deep and layered, coarse fertilizer with fine fertilizer and shallow, and late-acting fertilizer and fast-acting fertilizer combined. Since the root system of sweet potatoes is mostly concentrated in the soil layer of about 30 cm, if the basal fertilizer is applied here, it is conducive to the absorption of the root system. In particular, phosphate fertilizer, due to low solubility, phosphate ions diffuse very slowly in the soil, so it is more necessary to apply to the distribution layer of sweet potato roots.

Second, the top dressing should be accurate, timely and fast-acting to meet the needs of sweet potatoes in various critical periods.

1. Seedling fertilizer, nitrogen fertilizer can be applied about 7 days after cuttings, mainly based on urea, insert a small hole with a stick next to each stick, and then put a small pinch of urea into it and then seal the soil and water enough. Or use human manure and urine to mix about 3 times of water, apply about 600kg per mu, and pour it near sweet potato seedlings.

2. Strong seedling fertilizer, about 40 days after cuttings, about 5 kg of ammonia nitrate and about 10 kg of potassium sulfate can be applied per mu, which can make the stems and leaves grow early, seal the ridge early and set potatoes early.

3. Potato fertilizer, about 100 days after transplanting, at this time sweet potatoes have been formed, mainly potassium fertilizer, about 10 kg of potassium sulfate per mu, or about 150 kg of plant ash per mu.

Sweet potatoes can not use nitrogen fertilizer, otherwise it will cause the stems and vines to grow and waste nutrients, and the sweet potatoes should be fertilized with organic fertilizer or phosphorus and potassium fertilizer, which can make the roots of sweet potatoes expand.

You can't apply some farm manure, because these fertilizers are very bad and will reduce the yield of sweet potatoes, so we should apply some cow manure to sweet potatoes, so that we can increase the yield of sweet potatoes.

Avoid applying more nitrogen fertilizer, more nitrogen fertilizer affects the utilization of potassium fertilizer, sweet potato in the growth process, seedlings mainly need more nitrogen fertilizer, planting sweet potato, avoid only applying basal fertilizer once in a lifetime, applying fertilizer once in a planting season, also known as "a bombardment" fertilization method, although this fertilization method, can save the labor of fertilization in the middle, it is not conducive to sweet potatoes to create a higher yield, sweet potatoes from planting to harvesting, about 160 to 200 days, the growth period is longer, to the later sweet potato rhizome expansion period, Obviously, the fertilizer is insufficient, the sweet potato rhizome expansion period is the peak period of sweet potato fertilizer, therefore, sweet potato fertilization, in addition to the farmhouse fertilizer once applied, the rest of the chemical fertilizer, need to be reserved for about 40%, respectively, in the sweet potato seedlings to 50 60 cm or so apply 20%, the remaining 20% in the sweet potato expansion period, as a crack fertilizer to apply, sweet potato crack period especially to increase the amount of some potassium fertilizer, in this 20% of the fertilizer, each mu is mixed with 10 kg of potassium sulfate to apply, At the same time, combined with foliar spraying, 1000 times liquid high-concentration phosphorus and potassium foliar fertilizer + Tianda 2116 special foliar fertilizer for stem expansion.
