Potato fertilizer demand is large, how to fertilize potato planting?

There are 360 people in each field, and they can become leaders in their fields. Do everything should be the same as them, not to be perfect, but to be perfect, in today's agriculture is more and more to the edge of science and technology, it is very convenient to do a good job of farming, but the technology required is also superb. So there is a large demand for potato fertilizer, how to fertilize potato planting, follow you to understand.

Take care to apply base fertilizer to the potatoes.

Potatoes like a shady environment when growing, so we should provide fertile and loose soil for potatoes, and because the growth period of potatoes is relatively short, we need to prepare rotting fertilizer, and improve the soil environment, which can promote the emergence of potatoes.

Base fertilizer. Before planting this plant, you can use some moderate amount of base fertilizer, and you can sprinkle the fertilizer directly into the soil when turning the soil. When choosing fertilizer, you generally use farmhouse fertilizer, and you can also put some fertilizer containing nitrogen, phosphorus and potassium in it, and mix them thoroughly before sprinkling them into the soil.

If you want to increase the yield of fruits, you should increase the use of fertilizer, but do not overdo it, as it will cause seedlings to burn. It is important to note here that basal fertilizer is not used after planting.

Take care to supplement potatoes with potassium.

According to the experience of some old potato growers, the demand for potassium fertilizer during the potato growth period is relatively high, because if potatoes want to improve their yield, they must pay attention to supplementing potassium fertilizer, you can supplement the corresponding potassium sulfate, and then pay attention to soil cultivation, apply potassium fertilizer in the process of weeding, which can improve the yield of potatoes, and is a fertilizer that can not be ignored in the process of potato planting, so you can not ignore it.

Seed fertilizer. When planting potatoes, you must fertilize the right amount to help it grow in the future. When fertilizing it, we generally use furrow application, which will not cause damage to its roots, and can also reduce some labor costs when using fertilizer.

If you want to have a high yield of potatoes, then fertilizer must be indispensable, and the above is the detailed fertilization method of potatoes.

It is best to be in the northern or southern part of China. It is necessary to top dressing in time. You can use some urea and spray it 15 or 20 times a day, preferably three to 4 times.

Squirt once a week. You can also use some compound fertilizers, preferably around 50 kg to 60 kg. Then use some potash, about 10 kg to 13 kg.

Choose a good piece of land, and try to choose a place with a cooler temperature, so that the potatoes can grow better and better.

Before planting potatoes, the land should be fertilized to ensure the nutrients of the land, and the potato seedlings will grow again, and the land should be fertilized within two months, and when the potato seedlings are fully developed, the potatoes should also be fertilized, so as to ensure the healthy growth of the potatoes.

Fertilize potatoes when planting, and then fertilize them after the potatoes grow seedlings, and then fertilize them when they grow up, and then fertilizer them according to the growth date of the potatoes.

You can fertilize the soil before planting, and then plant potato seedlings in the ground when it is appropriate, and you can do frequent weeding, fertilization and watering.

First of all, in terms of fertilizer types, farmers (organic fertilizer) are mainly used as the main fertilizer and chemical fertilizer as a supplement; From the fertilization period, "it is necessary to base fertilizer as the basis and top dressing as a supplement". Why should farmyard manure be the main fertilizer? From sowing to emergence, seed potatoes respire vigorously in the soil and need sufficient oxygen to facilitate the transformation of starch, protein and other storage substances.

Field management should focus on improving ground temperature and enhancing soil aeration. The main measures are to use shallow hoeing to loosen the topsoil and increase the ground temperature.

<> potatoes have a short growing period and require more fertilizer. For potatoes, fertilizer is the basis of high yield, without enough nutrition, potatoes can not obtain high yield, therefore, in the planting process, we must often add all kinds of fertilizers required by potatoes, mainly nitrogen fertilizer, potatoes are generally planted in dry land, spring rainfall is small, top dressing is difficult, so, basically take a bombardment way, if only the flowering period rainfall in the budding period, or there are irrigation conditions, it is best to top dressing 1 2 times. Therefore, the base fertilizer must be sufficient.

As the saying goes, crops are a flower, all rely on fertilizer, no fertilizer or less wrong application, not to mention the yield does not go up, not to mention the quality of the product. Potatoes are very sensitive to fertilizer, especially like potassium and sulfur fertilizer, potatoes are more sensitive to fertilizer, fertilizer tolerance especially likes potassium and sulfur, in the growth process of the demand for nitrogen, phosphorus and potassium nutrients in the potassium fertilizer is the most, nitrogen is second, phosphorus is less, for our growers to choose 2000 kg of farm fertilizer per mu when planting potatoes.

Potatoes can also be sprayed with foliar fertilizer, spray potassium dihydrogen phosphate and urea in the early stage of potatoes starting to bloom, spray with warm water to melt with water, half a month after the leaf fat seedlings are strong, the color is bright, it is the beginning of autumn to see autumn, potatoes are definitely harvested for the dog days. One is potassium fertilizer for potato dressing. According to our years of planting experience, we also like to use plant ash instead, first of all, we can use plant ash and cut potatoes to mix seeds, and secondly, we can also burn the plot of land where potatoes are about to be planted, and mix plant ash in the soil.

When planting potatoes, it is best to use chemical fertilizer, so that the recovery effect is very good, and this chemical fertilizer should not be too much, each time it should be mastered, so as to achieve the effect.

In the summer high temperature and rainy environment is more suitable for potato topdressing, the first topdressing is seedling fertilizer, and the seedlings of 80 grow to 12-16cm is fertilization. Top dressing can be carried out together with cultivated soil, and urea mixed with water can effectively promote the growth of stems and leaves of plants.

It is better to use nitrogen fertilizer for top dressing, which can give the potatoes a good transition to flowering, and then potassium fertilizer can be added.

More organic fertilizers or fertilizers with trace elements such as nitrogen, phosphorus, potassium, and iron should be applied. This will help increase the yield of potatoes.

Potatoes have a large demand for fertilizer, according to the actual situation, farmyard fertilizer, diammonium, urea, etc. are used as base fertilizers with light and nutrient film fertilizers, and new high-fat films are used to help potatoes absorb light energy, enhance fertilizer efficiency, prevent bacterial infection and improve their ability to resist natural disasters, so that potatoes can thrive and increase yield.

You can spray some nitrogen fertilizer, but you can also spray some organic fertilizer, such as phosphate and potassium fertilizer, and you can also add some biological fertilizer.

First of all, during the potato seedling period, it is necessary to increase the use of nitrogen fertilizer, because the newly cultivated plant needs nitrogen fertilizer to promote plant growth, and can be diluted with fast-acting fertilizer for spraying or fertilizing with watering, which can promote plant growth.

Potato base fertilizer should be reapplied, the amount generally accounts for more than 2 3 of the total amount of fertilizer, the amount of nitrogen fertilizer accounts for about 50%, with fully decomposed farmhouse fertilizer as the main oak, a certain amount of fertilizer, especially phosphate fertilizer and potassium fertilizer, which can improve the physical properties of the soil, the second is potato seedling fertilization is also critical, can be combined with cultivating weeding, soil cultivation together, at this stage it needs more nitrogen fertilizer, to nitrogen fertilizer-based.

Potato requires a cool climate, likes loose sandy soil, short growth period, potato seedlings need fertilizer is generally not too large, to the tuber differentiation period to begin to demand fertilizer to reach the peak period, fertilization should have more farm fertilizer with chemical fertilizer as base fertilizer, according to the local climate characteristics to choose high yield, disease resistance, good quality, good taste of early or early potato varieties. The fresh food varieties for export should have a good potato shape and appearance, shallow bud eyes and smooth potato skin.

Potatoes prefer compound fertilizers that are high in potassium, medium nitrogen, and low in phosphorus. It is necessary to observe the combination of farm manure and chemical fertilizer; Combination of base fertilizer and top dressing; Combination of large, medium and trace elements; The principle of balanced fertilization and total nutrient fertilization. Potatoes can be sown at low altitudes from December of the current year to January of the following year (winter planting, spring and summer harvesting), and covered with mulch film after sowing, so selecting the right potato variety and sowing it early at the right time can increase the yield of potatoes.

Under normal circumstances, Xunling calendar does not need to be watered in the seedling period, if the soil is too dry, it can be watered appropriately, but it is necessary to raise the ground temperature in time, and the buds should be watered frequently according to the soil business conditions and small water, to ensure that the land is not dry, generally watered once in about 10 days.

The land should be fertilized before potatoes are planted, and the land should be fertilized one month after the potatoes are planted in the spring oak field, and fertilized after the potatoes have grown, so as to ensure that the potatoes are nutritious.

Oxygen is needed for the growth of both potato roots and tubers. Therefore, it is required that the land is leveled, and after watering, there can be no water accumulation or dry and lower temperature, and the imitation tillage layer of Qiaoqin should be deep and loose. The basal fertilizer is required to be a fully decomposed organic fertilizer, half of which or 2 3 is turned into the tillage layer, and the rest is applied when the sowing furrow is opened.

The application rate per mu is 2000. Before sowing, combined with the application of the first bucket of seed fertilizer, mixed with the control of underground pests, the amount of fertilizer per mu is: urea sensitive fiber calcium and phosphorus fertilizer 10 15, plant ash 25 50.

First of all, it is necessary to make the limbs of these lands relatively soft, and then sprinkle these fertilizers in the land according to the example of the source of hunger, and it is best to sprinkle some organic fertilizer and urea in more than one state.

It is an organic fertilizer made of beneficial microorganisms and other inorganic fertilizers and decomposing fertilizers, and its application is mainly to put a large number of live beneficial microbial populations in the soil, multiply in large quantities, accelerate the decomposition of soil organic matter through the activities of beneficial microorganisms, improve the decay of soil and other residues, improve the aggregate structure and physical and chemical properties of the soil, activate the soil to enrich soil fertility, and improve soil permeability. Although there are other trace elements in it, there is no need to use chemical fertilizers in large quantities because of the presence of live microorganisms and the amount of nutrients required for the normal growth of potatoes.

As for the planting of potatoes, potatoes like to use phosphorus and potassium fertilizers, and the demand for phosphorus and potassium is large, but the nitrogen fertilizer in the growth is essential, and the amount can be increased at any time according to the top tips of the growth stage, so as to achieve the balance of vegetative growth and reproductive growth, and avoid the situation that potatoes only have long stems and leaves and do not bear fruit or have many and small cones. Therefore, when planting potatoes, it is necessary to choose a deep and loose sandy loam soil, apply enough farmhouse fertilizer to the bottom fertilizer, use 10 kg of ammonium sulfate per mu (it is strictly forbidden to use ammonium chloride, potatoes are chlorine discarded crops), 15 kg of calcium, magnesium and phosphorus fertilizer, and 50 kg of plant ash (we have Ku Ding Xie Niu, Kang plant ash is specially used for planting potatoes).

When planting soil and ridges, control nitrogen fertilizer, mainly phosphorus and potassium, so that the fertilizer is applied, the potato growth condition is good, and the potato yield is high. Potatoes are a potassium-loving crop, and potassium fertilizers should be used in the cultivation process. During potato growth, potassium is twice as much as nitrogen and five times as much phosphorus.

Do not use chlorine compound fertilizer and biological fertilizer to expand and corrode the potato root ball, resulting in trachoma, insect eyes, and uneven potato surface, which affects the appearance! In the process of potato planting, sufficient base fertilizer should be applied, and 2000 kg of rotted farmer's organic fertilizer, 150 kg of plant ash, and 15 kg of potassium sulfate compound fertilizer should be applied per mu.

At the potato seedling stage, nitrogen fertilizer can be appropriately applied to raise seedlings, 5 kg per mu, and at the flowering stage of the land, water-soluble potassium sulfate can be used, or sprayed, or dropped. At the same time, superphosphate, magnesium sulfate, borax and other fertilizers can be applied. Potato growth can be regulated by foliar potassium monobasic phosphate sprays.

Do everything possible to avoid the use of potassium chloride and potassium chloride compound fertilizer, and the fermentation method can be used for farmhouse organic fertilizer.

1. The focus of potato planting and fertilization is potassium fertilizer, which promotes the expansion of tubers, and the absorption of chemical fertilizer by potatoes in the whole growth period is the most potassium fertilizer, followed by nitrogen fertilizer, and the least phosphate fertilizer, and other trace element fertilizers such as calcium, boron, copper, and magnesium are also indispensable for potato growth.

2. Base fertilizer is also base fertilizer, which is generally made of organic fertilizer, which provides nutrients for crops throughout the growth period, creates good growth conditions for the growth and development of crops, and fertilizes the soil. Potatoes are tuber plants, like loose and breathable soil environment, the use of fully decomposed organic fertilizer as a base fertilizer can improve soil quality, is conducive to the growth of potatoes and potato formation. Farmhouse fertilizer can be fully decomposed chicken manure, soybean meal, grass ash; Researchers found through research that the base fertilizer using chicken manure, compound fertilizer and urea ratio yield is the highest, tuber starch content is the highest, than a single application of organic fertilizer per mu yield is about 800 kg higher, starch content is 1% higher, than the application of compound fertilizer yield, quality is also much higher, so the application of base fertilizer should follow the principle of farm fertilizer, fertilizer as a supplement.

3, the amount of base fertilizer accounts for more than half of the total amount of chemical fertilizer in the potato growth period, to apply enough at one time, generally 2000 to 3000 kg of rotted organic fertilizer can be used per mu, and then with the use of three elements of chemical fertilizer, 12 kg of urea per mu, 20 to 30 kg of superphosphate, 10 to 15 kg of potassium sulfate (or 150-200 kg of plant ash), these fertilizers are mixed evenly and used, and the amount of chemical fertilizer can be appropriately increased in high-yield potato areas.
