Is it better to spray or sprinkle calcium fertilizer on leeks?

The calcium fertilizer used in leeks is generally sprayed, the calcium fertilizer is dissolved in water, and then sprayed through agricultural equipment, which is more uniform and easy to absorb.

It is better to apply calcium fertilizer to leeks because they can be sprinkled directly in the soil and then penetrate into their roots.

Of course, the leeks are sprinkled, so that the leeks will be very clean and very healthy.

Hello, it doesn't matter, you can spray it, you can sprinkle it directly, but you can't sprinkle too much. Be diligent, watering will grow well.

Personally, I feel that fertilizing leeks should be better than sprinkling them in the ground. Because if you spray fertilizer, it will fall on the leaves. Nutrients are not absorbed by the roots.

Leeks apply calcium fertilizer, I think it should be a stupid thief, because if he is stupid, he can get all his geographical images, and if you spray it, it will be easy to get on him.

Well, hello, the goods of leeks in general, look at the elders in my family, they are all stupidly fat, they should be stupidly fat, everyone is stupid fat, and then it always grows out and it tastes delicious, you can try it.

Which method is better to apply this fertilizer to leeks, there are no unified regulations and requirements, and it is okay to use any method. You can do it according to the actual situation.

The time of leek fertilization, the best time for top dressing is in the leek field flower ditch, and then buried in the soil.

Planting leeks should avoid applying these three fertilizers.

1. Nitrate nitrogen fertilizer.

Leeks like nitrogen, nitrogen fertilizer for the growth of leeks has played an important role in promoting, but in the application of nitrate nitrogen fertilizer should be noted, the concentration is too high easy to burn roots and fertilizer damage, so if the application of nitrate nitrogen fertilizer should be controlled, not too much at one time, even on cloudy days to reduce the amount of use, can not be mixed with compound fertilizer and water soluble application.

2. Undecomposed farmhouse fertilizer (also known as organic fertilizer).

1) Farm fertilizer includes human manure, manure, livestock and poultry manure, etc., its advantage is that the nutrients are relatively comprehensive, abundant, easy to take materials, low production cost, and also has a very large ability to improve soil fertility, which is a very ideal fertilizer for crop planting. The fertilizer effect of farmhouse fertilizer is slow and lasts for a long time, and it has an irreplaceable role as a base fertilizer.

2) But the use of farmhouse fertilizer needs to be fully decomposed, on the one hand, the nutrients in it can be effectively absorbed, on the other hand, the unrotted farmhouse fertilizer will release a lot of heat in the process of fermentation, if directly applied will burn the roots of crops and even burn the crops, at the same time, there are many harmful bacteria and pests and diseases in the unrotted farmhouse fertilizer, which will cause harm to crops.

3) Therefore, the farmhouse manure can only be used after it is fully decomposed, that is, it is piled up for more than 60 days, it becomes black and rotten, there is no big lumps, and it feels loose and soft when grasped by hand.

3. Ammonium carbonate (ammonium bicarbonate).

Ammonium carbonate is also often used as a nitrogen fertilizer, which can promote the photosynthesis of crops and promote seedling growth. But it has a disadvantage, that is, it is volatile, the utilization rate of nitrogen is relatively low, and if it is not properly disposed of, there is too much residue on the surface, and the ammonia formed by volatilization will smoke the leaves of leeks, so it should be applied in a ditch and covered with soil in time.

Leeks can be sprinkled with plant ash, which can not only improve nutrition, but also make wounds heal quickly and prevent bacterial infections.

Note: Grass ash is alkaline, and must not be mixed with human and animal manure, manure, ammonium sulfate, and ammonium bicarbonate, so as not to cause nitrogen volatilization and failure. In rural areas, many people pour plant ash directly on the farmhouse manure, and then ferment together, which is the wrong way to operate, and plant ash is best used alone.

1. Leeks should not be applied to the fertilizer nitrate nitrogen fertilizer, if you want to make the leeks grow better, you can apply nitrogen fertilizer, you must know that nitrogen fertilizer can better promote the growth of leeks, although nitrate nitrogen fertilizer is also very good, but its concentration is very good, if you want to use, you must control the concentration, otherwise there will be fertilizer damage, use it in bad weather, but also pay attention to the concentration, to avoid damage to plant roots.

2. Do not use organic fertilizer for leeks, in fact, organic fertilizer is not decomposed organic fertilizer, such as manure, agricultural fertilizer, etc., which are not suitable for the maintenance of leeks, these undecomposed fertilizers are easy to cause damage to the roots of plants, and at the same time, they are prone to such pests and affect the growth of leeks.

3. Ammonium bicarbonate (ammonium bicarbonate) is also not suitable for the maintenance of leeks, and the use of this fertilizer is easy to affect the root growth of leeks, and the leaves will also be damaged.

What kind of leeks are good to use in the growing season, and how much is the content.

1. Leeks should not be applied to nitrate nitrogen fertilizer, if you want to make leeks grow better, you can apply nitrogen fertilizer, you must know that nitrogen fertilizer can better promote the growth of leeks, although nitrate nitrogen fertilizer is also very good, but its concentration is very good, if you want to use, you must control the concentration, otherwise there will be fertilizer damage, use it in bad weather, but also inject the unintentional concentration, to avoid damage to plant roots.

2. Do not use organic fertilizer for leeks, in fact, organic fertilizer is not decomposed organic fertilizer, such as manure, agricultural fertilizer, etc., are not suitable for the maintenance of leeks, these undecomposed fertilizers are easy to cause damage to the roots of plants, and at the same time, they are prone to such pests, affecting the growth of leeks.

3. Ammonium bicarbonate (ammonium bicarbonate) is also not suitable for the maintenance of leeks, and the use of this stupid crack fertilizer is easy to affect the root growth of leeks, and the leaves will also be damaged.

Leeks are good for applying grass ash fertilizer.

Grass ash is the ash left behind after the plant burns, plant ash is a high-quality potassium fertilizer (the main component is potassium carbonate), and leeks are a potassium-loving crop, so applying plant ash can promote the growth of leeks. Secondly, plant ash is also rich in mineral elements, such as iron, calcium, magnesium, boron, zinc, etc., to leeks can prevent leeks from "deficiency" reed, can regulate the metabolism of plants, and the taste of leeks with plant ash is better.

Many people will have the phenomenon of "cutting more and more fine" when planting leeks, the main reason is that the root system of leeks is weak and the root system is not developed, and the more developed the root system of leeks, the stronger the regeneration ability. In addition to providing nutrients directly, plant ash can also improve the soil, and the soil will be looser when applied with plant ash, which is conducive to the development of leek roots. Leeks have a well-developed root system and are more able to absorb water and nutrients.

Types of leeks

1. Fine-leaved leeks.

Fine-leaved leeks belong to the traditional vegetables of the farmer's family, also called local fine leeks, the leaf color is light green and relatively thin, the upper part is bent, the quality is soft, the fiber is more, although the yield is low, but the leek fragrance is relatively strong, the taste is good, soft and fragrant, so the rural people are most often planted. Local fine leeks grow fast, tillers are strong, the plants are not high, the leaves are not long, heat-resistant, cold-resistant, and wind-resistant, often planted in the open air, and flower stems can be harvested.

2. Large-leaved leeks.

This type of leek is a hybrid variety, and we also call it large-leaf leek, sweet and crisp leek. Compared with local fine-leaved leeks, the leaf color is dark green, the leaves are thick and wide, and the taste is crisp and sweet. Large-leaved leeks can be cultivated in the open field, or they can be planted in solar greenhouses, plastic greenhouses, etc.

3. Broad-leaved leeks.

This kind of leek is called a big leek, and some places are called Pifeng pants, the leaf color is light green, and the leaves are thick and soft. Large leeks have fast growth speed, strong tillering ability, heat resistance, cold resistance, wind and rain resistance, but because of the light taste of large leeks, they generally do not eat lightly, but mainly harvest leek flowers and leek roots.

Leeks are also called lazy vegetables and yang vegetables. Leeks can be harvested for a few years as long as they are well managed after a year of planting, it is a perennial herbaceous plant, and it is also a more common vegetable in our lives. Leeks themselves have a special smell, and leeks can be used not only as a vegetable, but also as a very wide range of medicinal uses.

What kind of fertilizer do we need to apply to grow leeks in the countryside?

Although leeks are relatively easy to grow, fertilization during the growing period is also more important. There are several main links in fertilization during the growth of leeks:

First of all, leeks are suitable for growing in loose, fertile, and deep soil plots. At the same time, the soil with high soil drainage is required to be more suitable for the growth of leeks. For base fertilizer, it is best to use well-rotted cow manure, pig manure and other animal manure in our rural areas, and at the same time mix some potassium sulfate compound fertilizer as base fertilizer.

Generally, 2500 kg of rotting farmhouse fertilizer + 15 kg of potassium sulfate compound fertilizer can be applied together per mu.

Top dressing is the key to seedling fertilizer leeks will enter the seedling stage after transplanting, at this time we should top dressing in time to promote the growth of leeks stems and leaves. At this time, it is mainly allowed to apply well-rotted human urine fecal water, or 20 kg of urea per mu.

Top dressing after one round of harvesting is done in order to make the leeks after the later harvest grow again quickly. After we harvest leeks for a round, generally after four or five days, the wound at the harvest site has healed, then we can carry out top dressing. At this time, the top dressing is mainly rotten human urine fecal water or rotten manure.

This is very beneficial for promoting the growth of seedlings.

Finally, the skillful application of overwintering and summer fertilizer leeks is more fragile in hot summers and cold winters. At this time, we should properly sprinkle some compound fertilizer or well-rotted manure to improve the growth of leeks and the ability to resist harsh environments.

Leek is a perennial root vegetable, which requires a large amount of fertilizer during the growth period, and after each harvest, it also needs to be topdressed to promote the growth of leeks. If you only need leek leaves, you need to apply nitrogen fertilizer, and if you want to flower and bear fruit, you need to apply phosphorus fertilizer, potassium fertilizer before flowering.

Nitrate nitrogen fertilizer, unrotted farmhouse fertilizer, plant ash, etc. are recommended for leek fertilization.

1. Sheep dung. Sheep manure has a high organic matter content and can significantly increase soil fertility after application. Secondly, sheep manure can loosen the soil, and the effect of improving the soil is obvious.

Thirdly, sheep manure is rich in potassium, which can promote the synthesis and transportation of carbohydrates, and it can be said that sheep manure is a high-grade organic fertilizer.

2. Cake fat. Cake fertilizer is the residue left after oil extraction such as rapeseed cake, peanut cake, soybean cake, etc., the content of organic matter in cake fertilizer is very high, and the calorie of cake fertilizer is very high, and it must be fully decomposed before it can be applied. The cake fertilizer needs to be stacked for 3 months under natural conditions to complete fermentation, if you want to ferment the cake fertilizer quickly.

3. Grass ash.

If you have plant ash at home, then it's best to grow leeks with plant ash. The main component of plant ash is potassium carbonate, which mainly contains potassium, and it also contains almost all micronutrients such as iron, zinc, silicon, boron, molybdenum, etc.

Precautions for leek farming

1. Seed selection.

It is recommended to choose full, no impurities, no insect mouth, cold and insect resistance, heat resistance, and strong tillering varieties.

2. Treat the seeds.

Dry it for one to two days, then put it in water about 40 degrees for cleaning, soak it for half a day when the water temperature reaches about 30 degrees, and then put it at room temperature for germination, 85% of the seeds can be sown when they begin to sprout.

3. Strengthen field management.

After planting, water twice in a row, hoe and squat seedlings in time, the soil is semi-dry and wet, and it should be drained in time when it enters the rainy season. Due to the heavy rain in summer, it is necessary to reduce the amount of watering and pay attention to drainage and timely clean up the yellow leaves and leeks near the ground according to the actual situation.
