Before planting potatoes, you must use base fertilizer, what kind of fertilizer is best as base fert

I believe that most people like to eat potatoes. And it's a staple food that most people love to eat. It is one of the four major grains in China.

Especially seeing that children love to eat baked potatoes, chips, and mashed potatoes, and not knowing how popular potatoes are, and the area where potatoes are planted is also huge. So how do you fertilize potatoes? Potatoes are stem plants that prefer loose soil and low-temperature vegetables.

The basic fertilizer is mainly completely rotten farmhouse fertilizer, which is evenly mixed after full maturity, and is suitable for deep soil turning. Then add a certain amount of chemical fertilizer, especially phosphorus and potassium fertilizer as the base fertilizer, which helps to improve the physical properties of the soil and produce growth and sweet potatoes. 4000 5000 catties per square meter is appropriate, and nitrogen, phosphorus and potassium should be used at the same time when applying chemical fertilizers appropriately.

Potatoes have a great demand for potassium, and the scientifically reasonable nitrogen-potassium permeability ratio is: 1:.

Summer rain is a critical period for autumn rains for potatoes. The autumn rain is divided into two parts. When the sapling is about 15 cm tall after hair removal, combined with Chongqing soil, spray 5 8 kg of Wudang water to promote the growth of stems and leaves and promote potato fertilizer, which is carried out in the germination period of the plant and the period of sweet potato bearing, so as to meet the nutrients required for sweet potatoes, promote early potato formation, and more potatoes.

Autumn weeding and weeding in Chongqing was carried out when the height of the plants in Laixi County was about 40 cm. In the top dressing, 2 3 nitrogen fertilizer catches up with the nursery fertilizer again, and the remaining 1 3 nitrogen fertilizer is topdressed according to the plant growth situation. Try not to use fertilizers that are high in chlorine.

Potatoes are a prohibited crop for goats, and the application of goat fertilizer can affect the formation and accumulation of starch, affecting the quality of tubers. It is best to use potassium sulfate-type fertilizers for growing potatoes.

Potato cultivation is simple. The technical requirements are relatively low, and the yield is also very large, which is a very suitable crop for promotion, but it is a very important food**, and has a very important position in the field of food and feed. During tuber formation, the demand for fertilizer begins to increase rapidly, peaking during this period, but eventually the amount of fertilizer decreases rapidly again.

There is a high demand for nitrogen fertilizers during each farrowing period. In particular, the demand is highest at the seedling stage. Therefore, in production, attention should be paid to the application of phosphate fertilizer at the stem maturity stage and seedling stage, and the lack of it will have a great impact on potato growth.

During the whole growth period, potassium fertilizer is absorbed the most, followed by nitrogen fertilizer, and attention should be paid to adjustment when fertilizing. In addition to these fertilizers, the application of farm fertilizers is also important. Farm fertilizer not only contains ternary fertilizer, but also contains a large number of trace elements and beneficial microbial communities, which improve the soil environment and help potatoes grow.

Excessive fertilization during the growing season will harden the soil, and the use of farmhouse manure can make the soil soft and aerate, while improving the conserved ability of the soil, which helps the roots to breathe and absorb. In addition, farm fertilizers are also cheap, which helps to reduce the cost of fertilization. Farmyard fertilizers provide organic matter and beneficial bacteria that can promote crop uptake, release large amounts of carbon dioxide, improve photosynthesis, and promote nutrient storage.

Generally, the base fertilizer is mainly organic fertilizer, supplemented by potato-specific potassium sulfate compound fertilizer, and about 45-50 kg of potato-specific fertilizer per mu. Top dressing: Generally, top dressing should be applied skillfully to see how the potatoes grow?

Fertilization as appropriate, when the common topdressing is full seedlings, combined with cultivated soil, topdressing organic fertilizer or fast-acting fertilizer, and watering in time after fertilization; The second topdressing is in the budding period, when the potato tuber is expanded, the amount of fertilizer required increases, it is the period when the amount of fertilizer is the largest, and the special fertilizer for potatoes can generally be applied to 5 15 kg per mu, and it is generally not topdressed after sealing the ridge. Seed fertilizer: Look at the soil nutrient content, if the nutrient content is low, you can apply 15 20 kg of potato fertilizer per mu to make seed fertilizer.

Seed fertilizer is generally applied in furrows or holes, and cannot be in direct contact with seed potatoes. Common potato-specific potassium sulfate compound fertilizer formulas are % (17-17-17) and other common formulas. These common products contain high-quality humic acid, which not only improves the yield and quality of potatoes, but also improves soil properties and increases soil organic matter content.

Potatoes are really a vegetable with a very wide audience, especially loved by children, and potatoes are very low in calories, and they are also very suitable for ** people to eat! In the early stage of potato planting, using expired stick noodles as a base fertilizer can be said to be a very good choice! Not only does it achieve the effect of waste utilization, but the effect is also very good!

Fertilizing potatoes generally uses potassium-based fertilizers, and can also be combined with some phosphate and nitrogen fertilizers to make the plants grow better, and at the same time, you need to choose the right time period when fertilizing potatoes, and it is best to fertilize the plants during the period when the plants are growing vigorously, so that the plants can absorb enough nutrients.

Bacterial fertilizer is a fertilizer made of beneficial microorganisms and other well-decomposed organic fertilizers, its application is mainly to put a large number of living beneficial microbial populations into the soil, multiply, through a large number of beneficial microbial activities, accelerate the decomposition of soil organic matter, and promote the planting process of other residual potatoes in the soil, to apply foot fertilizer, 2000 kg of rotten farmer organic fertilizer per mu, 150 kg of plant ash, 15 kg of potassium sulfate compound fertilizer. After the emergence of potatoes, nitrogen fertilizer can be appropriately applied to extract seedlings, 5 kg per mu, and water can be applied during the flowering period of the land. <>

Potatoes like to buy large, neat, smooth skin, healthy and disease-free, so when planting potatoes, it is best to reapply organic fertilizer, organic fertilizer can improve the air permeability of the soil, increase plant disease resistance, and reduce the amount of chemical fertilizer. Generally speaking, calcium, magnesium, boron, zinc and other trace elements! Its main function is that on the one hand, the active bacteria contained in it can improve the soil environment, increase the content of soil organic matter, and at the same time inhibit the growth of other colonies and increase the number of beneficial colonies!

On the other hand, if you do not pursue the yield of organic matter in bacterial fertilizer and large and medium, it is also possible to use only bacterial fertilizer and organic fertilizer! First of all, let's first understand what is bacterial fertilizer, bacterial fertilizer refers to biological fertilizer containing specific microorganisms, used in agricultural production, through the life activities of the microorganisms contained in it, in the process of potato growth to timely top dressing, seedling stage to nitrogen fertilizer, with about 7-8 kg of urea per mu with water. After the potatoes flower, nitrogen fertilizer is generally not used, and potassium dihydrogen phosphate solution is basically used for foliar spraying.

It is not possible to grow potatoes using only bacterial fertilizer. Biological fertilizer can improve the soil and increase the content of soil organic matter, but it has the functions of potassium dissolving, phosphorus release and nitrogen fixation. Biological fertilizer is not only non-toxic and non-residue, but also can decompose the residue of chemical fertilizers and pesticides, and is a green fertilizer.

It is complex and extremely uneven.

When fertilizing, we must pay attention to the state of the potatoes and fertilize them at regular intervals. In general, fertilization once every three days is sufficient.

Skillful fertilization. The application of seed fertilizer can promote potato rooting, enhance the disease resistance of potato tubers, and prevent potatoes from being infested by soil pathogens and insect pests. For the selection of seed fertilizer, plant ash should be the best, for the following reasons:

1. The main components of plant ash are potassium carbonate and calcium carbonate, and sufficient potassium fertilizer and calcium fertilizer can promote potato rooting and germination.

2. Grass ash contains weak alkaline, which has the effect of preventing germs and insect pests, preventing potatoes from being infected with germs and insect pests, and reducing the probability of soil-borne diseases.

According to the soil fertility, combined with spring ploughing to apply rotting farmhouse fertilizer, pig manure is the best, followed by cow manure. Urea, diammonium phosphate, potassium sulfate and other chemical fertilizers should be applied in proportion, and calcium fertilizer and magnesium fertilizer should be increased according to the situation. Top dressing during its growth period is best foliar spray, with an interval of 5-7 days each time, and then appropriate addition of trace elements.

The cultivation of potatoes is very simple, the technical requirements are relatively low, and the yield is also very large, so it is a very suitable crop for popularization, but a very important food, in the field of food and feed, has a very important position. During the tuber formation period, the demand for fertilizer begins to increase rapidly, and the fertilizer demand reaches its peak during this period, but the fertilizer demand will decline rapidly in the end. In each growth period, there is a lot of demand for nitrogen fertilizer, phosphorus fertilizer, etc., especially in the seedling stage.

Therefore, in production, tuber maturity and seedling stage, we should pay attention to the application of phosphorus and nitrogen fertilizer, if it is lacking, it will lead to the growth of potatoes will be greatly affected.

Generally, plots with sugar-free yields of 2,000 kg should be used at the same time as 2,000 3,000 kg of decaying organic fertilizer, 25 kg of superphosphate, and 150 200 kg of superwood. After sowing potatoes and sprinkling diluted manure, a dosage of 800 kg per mu can be applied. Potatoes like fertile soil, add organic fertilizer, improve soil organic matter content, increase yield, improve quality, 40-50 kg of potato fertilizer per mu, kg of zinc sulfate, kg of boron fertilizer can be used as base fertilizer.

The basic fertilizer can be two-thirds of the ground, sprinkle the mixed fertilizer on the land, deep ploughing and turn to the soil below 5-20 cm, the remaining third can be used as fertilizer, before planting can be applied about 15 cm deep in the sowing hole or sowing furrow, pay attention to the fertilizer to minimize the contact with sweet potatoes, to avoid sweet potatoes being burned into fertilizer.

Bottom fertilizer is a basic fertilizer, generally made of organic fertilizer, which provides nutrients for the entire growth organ of the crop, and provides good growth conditions and fertilizer fertility for the growth and development of the crop. Potatoes are stem plants, which can alleviate a well-ventilated soil environment, and using mature organic fertilizer as a base can improve soil quality, which helps the growth of potatoes and potatoes. Farmyard manure can be made from cooked chicken manure, soybean meal and grass.

The researchers found that the proportion of cinnamon powder, compound fertilizer and urea was the highest, and the starch content of tubers was the highest, which was about 800 kg higher than the sugar-free yield of organic matter applied alone, and the starch content was 1% higher, and the yield and quality of compound fertilizer were also much higher.

The amount of base fertilizer accounts for more than half of the total amount of fertilizer used in the potato growth period, and it should be sufficient at one time. Usually 2000 3000 kg of decaying organic fertilizer is used per acre, and three elements of chemical fertilizer can be used at the same time, 12 kg of urea, 20 30 kg of superphosphate, 10 15 kg of potassium sulphate per acre. The application method is to combine two-thirds of the ground, sprinkle the mixed fertilizer on the ground and plough deeply, turning over the soil below 15 20 cm.

Of course, it is needed, because only by eating good base fertilizer can the potatoes grow bigger and have a higher yield, and the better one is the plant ash, because the plant ash not only has the effect of sterilization and insecticide, but also allows the seeds to form a protective film, so that the potatoes grow better.

To use, rot organic fertilizer.

Potato-based fertilizer, that is, base fertilizer, potatoes like loose and breathable soil, and the application of well-decomposed organic fertilizer can effectively improve soil quality, which is conducive to growth and potato formation. The base fertilizer can choose fully decomposed farmhouse fertilizer, such as chicken manure, soybean meal, plant ash, etc. It is understood that the base fertilizer is made of chicken manure, compound fertilizer and urea, which can obtain high yield and high content of tuber starch.

Any kind of feces can be used. <>

Potato planting and basal fertilization are very important for the early seedling growth of potatoes. Fertilizers rich in nitrogen and potassium are suitable for potato growth. The manure of some poultry and livestock raised by people is very good farm fertilizer after decomposition.

In terms of use, generally what you have at home is used. Like rural families, there are generally poultry and livestock such as chickens, ducks, pigs, and cows. There is not only rotting manure, but also rotting animal manure.

When planting potatoes, it is common to apply manure water as the base and then put rotten dry manure, which is more common in rural areas. <>

Manure is a kind of farmhouse fertilizer, and it is very good for the growth of potatoes when it is used as base fertilizer. However, if the manure is not yet ripe, it will take a certain amount of time to decompose. Direct application is easy to burn potato tubers, affect rooting and germination, and it is difficult to germinate or even grow seedlings.

Therefore, the manure must be rotted before it can be used as a base fertilizer to grow potatoes. In order to save trouble, some people finish fertilizing at one time, and then ignore it in the later stage, which is extremely unfavorable to the high yield of potatoes. We should top dressing according to the different periods of the potato, which is the key to high potato yield.

Excessive fertilization can not only lead to overgrowth and lodging of potatoes, but also to defertilization due to the short duration of the fertilizer.

The use of foliar fertilizer should be combined with potato spraying, and should be reasonably interspersed. Foliar fertilizer not only absorbs quickly, but also has obvious application effect, which can improve the stress resistance of potato, so as to supplement the shortcomings of slow nutrient absorption by roots, and quickly alleviate various problems caused by nutrient deficiency in potato. Ordinary foliar fertilizer can match water-soluble fertilizer with medium and trace element fertilizer, especially for zinc, boron, magnesium supplementation, especially sensitive; It can also supplement the corresponding nutrients according to different periods, such as appropriate spraying of liquid nitrogen fertilizer at the seedling stage; After flowering, because it is a critical period for the growth of potato roots, 200 grams of 99% potassium dihydrogen phosphate can be sprayed.

If possible, spray once every 7 days, and it is best to spray 2-3 times in a row.
