Garlic is a fertilizer loving and fertilizer tolerant crop, what to do if fertilizer damage occurs?

Some garlic is cultivated by mulching, and in this case, topdressing is mostly used with water. This situation can also easily lead to fertilizer damage in garlic, especially if the fertilizer is uneven. At this time, garlic appears to grow slowly, and fertilizer is uneven.

Although the absolute amount of fertilization is not large, it is not uniform enough, resulting in too high local nutrient concentration in the soil and seedling burning. The precaution is to fertilize as evenly as possible.

<> garlic seedlings emerge late and unevenly after sowing, and the garlic seedlings that come out are shaped like an awl, dark green in color, slow growth, and slow to develop leaves; The root system is rotten, and in severe cases, it cannot take root and emerge seedlings. Garlic farmers call this phenomenon "seedling burning", that is, fertilizer damage occurs. To know how to fertilize, we must first understand the characteristics of garlic fertilizer, it is a plant that requires a large amount of fertilizer, but the amount of fertilizer absorption is small and fertilizer-tolerant, and the application of organic fertilizer can significantly improve the yield.

Generally, fertilization is mainly based on basal fertilizer, supplemented by top dressing.

Later top dressing: the top dressing is generally carried out after the garlic sprouts are harvested, at this time the garlic sprouts have been harvested more than 50%, at this time potassium sulfate compound fertilizer can be used for topdressing, and the amount per mu is about 20 kg. Every garlic farmer wants to grow garlic with a large head of garlic, which requires understanding the root system of garlic to absorb nutrients.

The main root of garlic is mainly a string-shaped fibrous root, and the other fibrous roots are scattered in a small range, and the roots are all absorbed in the shallow soil. In our Jiaodong, garlic is an overwintering vegetable, generally sown in autumn, master the sowing from mid to late September to early October, more than ten days after sowing Qi seedlings, garlic seedlings to grow to 5-6 leaves before wintering, garlic seedlings height to more than 25 cm.

Rapeseed withered and peanut withered are the best organic fertilizers, which are high-grade gold fertilizers in fertilizer, and garlic is a very "low" crop (easy to feed), so it is enough to use this kind of fertilizer. When garlic sprouts are drawn, garlic sprouts and bulbs grow at the same time, and additional fertilization should be applied to promote the growth of garlic sprouts and bulbs when you see the tips of garlic sprouts. 25 grams of nitrogen, phosphorus and potassium compound fertilizer can be applied per square meter.

Although garlic is a crop that prefers fertilizer, excessive fertilization will lead to the death of garlic seedlings, and if there is fertilizer damage, the only solution is to replant.

First of all, it is necessary to dig up a part of the soil at its roots to keep the roots dry and avoid being attacked by the fertilizer in the soil again, and then water it to dilute it.

Garlic is a fertilizer-loving and fertilizer-tolerant crop, if the garlic seedlings are shaped like an awl, the color is dark green, the growth is slow, and the leaves are not developed for a long time, we need top dressing, at this time you can use potassium sulfate compound fertilizer for top dressing, the amount per mu is about 20 kg, and when you see the tip of the garlic sprout, you should add fertilization to promote the growth of garlic sprouts and bulbs. 25 grams of nitrogen, phosphorus and potassium compound fertilizer can be applied per square meter.

Application of calcium fertilizer: the application of calcium sulfate can relieve garlic poisoning; In the fields poisoned by excessive use of pesticides and herbicides, 40 kg of calcium sulfate per mu should be applied; In the plot where soil-borne diseases are severe, the amount of calcium sulfate should be increased for the first time.

At this time, it is actually necessary to spray some pesticides, which can solve many problems, but also pay attention to this amount.

In the event of this kind of harm, first of all, some organic fertilizer should be applied, or the appropriate type of compound fertilizer should be selected, which will also play a great role, or the choice of some herbicides is also very effective.

Phosphate and potassium fertilizers can be mixed to top dressing garlic, which can promote the balance of nitrogen fertilizer in the soil, which is conducive to absorption and utilization.

Garlic generally grows for about 250 days. Although garlic is not very absorbent, it is also a plant that needs fertilizer in particular. The fertilizer that garlic needs most is nitrogen fertilizer.

Therefore, when planting garlic, the main thing is to apply nitrogen fertilizer, do not apply nitrogen fertilizer all the time, and use some other fertilizers, such as phosphate fertilizer and calcium fertilizer.

Garlic requires a large amount of fertilizer during the growth process, and like other crops, garlic has the largest demand for nitrogen fertilizer during the growth process, followed by phosphorus and potassium fertilizers, as well as calcium fertilizers, magnesium fertilizers, sulfur fertilizers, etc.

In the growing season, you can use some foliar fertilization to allow garlic to better absorb nutrients, so as to improve the quality and yield of garlic.

<> for garlic planting, the scientific proposal of agriculture is still based on fertilizer, supplemented by top dressing, at present, the long-lasting fertilizer on the market is still relatively lacking, and for shallow root crops such as garlic, no matter how large the use of chemical fertilizer, it is difficult to maximize the fertilizer effect. Garlic fertilizer characteristics: In the germination stage, the root system of garlic mainly plays the role of absorbing water, and the amount of nutrients consumed during this period is small.

As the seedlings grow, the petals decrease due to the gradual depletion of stored nutrients, and eventually shrink. The scale and flower buds of garlic are differentiated in about 10 days, which is a critical period for fertility. From the end of flower bud differentiation to the harvest of garlic sprouts, the maximum demand for fertilizer and water is the period, and the root growth reaches its peak.

In the stage of land preparation and fertilization, it is recommended to choose the scheme of farmhouse fertilizer (organic fertilizer) with slow-release compound fertilizer, and the fertilizer effect of ordinary chemical fertilizer is too fast to play a good role in fertilizer effect. In addition, the root system of garlic is relatively shallow, so it is not very meaningful for excessive deep ploughing. Regarding the scientific rejuvenation of organic fertilizer, many friends choose unrotted chicken manure and pig manure as fertilizer, which leads to the flood of underground pests in the second year, especially maggots, so this must be paid attention to.

Due to the long growth period of garlic and the relatively shallow root system, the soil fertility of garlic is basically consumed after the beginning of spring. Timely topdressing can ensure the healthy growth of plants. Top dressing is mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer, of course, if you choose to apply compound fertilizer, the effect may be better.

Foliar spraying can also be used to promote absorption and improve the quality of garlic.

Generally in March and April when it is also relatively dry, at this time garlic is about to sprout, the demand for nutrients and water and fertilizer is relatively large, but also need to water garlic, at this time you can combine top dressing with watering flushing, the first stubble of garlic back to green period should not be watered too early, otherwise it is easy to occur in the spring cold, frost damage, resulting in reduced garlic production. When topdressing, you can choose humic acid water-soluble fertilizer to improve fertilizer efficiency.

If you want to fertilize garlic, you should sprinkle a lot of fertilizer on the soil to give garlic enough nutrients, because enough nutrients can make garlic grow and thrive.

Garlic should be fertilized manually, or by mechanization, which is faster, but the manual method is more refined.

Organic fertilizer can be used, or top dressing during fruiting periods, weeds should be removed during planting, and the timing of watering garlic should be paid attention to.

Soil preparation and fertilization of garlic Garlic should be planted in loose, well-drained, organic-rich soils, preferably sandy loam. Plots where garlic is planted should be ploughed and dried immediately after harvesting the crop, and the land should be prepared again before sowing. Bottom fertilizer should be applied before ploughing.

Second, due to the long growth period, high population density, and large amount of fertilizer, garlic is generally applied with high-quality organic fertilizers such as manure and manure.

5000 ~ 8000kg；Add 20-30 kg of phosphorus and potassium fertilizer. Organic fertilizer should be fully decomposed. If raw fertilizer is used, garlic roots will be burned during the fermentation process, and underground pests, especially ground maggots, will occur seriously.

It is necessary to make a fine plot with a width of 2 meters, preferably extending from east to west. Fertilization principles:1.

Scientific and reasonable fertilization should be carried out according to soil fertility and the needs of garlic in different growth periods.

Grasp the fertilization principle of "first light and then medium and heavy candidates", not only to prevent overgrowth in the early stage, but also to avoid fattening and premature aging in the later stage. 2.Fertilization:

Garlic plots need to be deeply cultivated and raked to enhance soil permeability, which is conducive to the activity of soil microorganisms and the transformation of soil nutrients, improves the storage capacity of soil, and is conducive to the development of roots and the expansion of bulbs. After the last crop is harvested, it should be ploughed as soon as possible to a depth of 20-25 cm. Introduction:

Garlic (scientific name: garlic), also known as garlic, garlic, garlic, gourd, solitary garlic, solitary garlic, is a general term for garlic plants. Semi-annual herbaceous plant, Allium in the lily family, is used as a bulbous medicine.

Harvest in spring and summer, tie up, hang in a ventilated place, and dry in the shade for later use. There is a saying in agriculture that "garlic grows in nine months and grows in nine years." "In June, when the leaves are dry, they are dug up, the silt is removed, and they are dried by ventilation or roasted until the skin is dry.

Garlic oblate or short conical, with gray-white or light brown membranous scales on the outside, peeling off scales, containing 6 10 cloves of garlic, rotating around the flower stem, disc-shaped at the base of the stem, and many fibrous roots. Each garlic clove is coated with a thin film, and when the film is peeled off, the white, thick, juicy scales can be seen. It has a strong garlic and spicy flavor.

It has a pungent smell and can be eaten or used as a condiment or medicine. Underground bulbs are divided into purple-skinned and white-skinned species according to different skin tones. During the Qin and Han dynasties, garlic was introduced from the Western Regions to the Zhongwei Laughing Pants Kingdom.

It is artificially bred and reproduced, has anti-cancer effects, and the public likes to see it.

When fertilizing, you can choose organic fertilizer, and you can also use some pig urine manure as the base fertilizer draft orange, and then in the later stage, you can also use urea, if it is planted in the south, so add some lime to the soil. At the seedling stage and overwintering of garlic, it is necessary to top dressing once.

Even during the growth period of garlic, frequent watering and fertilization, etc., at the same time, the hall should also do a good job of drainage, and also clean up the dead branches and leaves in the field in a large and timely manner, and also prevent pests and diseases, and also pre-roll fingers to prevent the scattering of garlic cloves.

Garlic should be combined with watering and fertilization, and timely weeding should be carried out in a timely manner. After the seedlings emerge, shallow hoeing and weeding at the second and third leaf stages, and the bridge and loose soil are kept pure and balanced. 4-5 leaves when the deep hoe is about 15 cm, the next year after the shallow hoeing, every 4 rows of garlic planing to repair the stalk, in order to top dressing, irrigation.

When planting garlic, first apply some fertilizer to the soil, then apply some fertilizer after planting, and then apply fertilizer according to the growth cycle of garlic.

Garlic is a very common seasoned vegetable. It can be used not only as a vegetable, but also as a medicine. It is rich in nutrients such as proteins, oligosaccharides, and polysaccharides.

Regular consumption prevents cardiovascular diseases and fights tumors. It is best grown in deep, loose, well-drained loam and sandy loam soils, so what fertilization principles should be followed to grow garlic? Next, let's check it out!

Garlic needs to be fertilized.

Generally speaking, the growth period of autumn-sown garlic is relatively long, taking 8-9 months. During this period, the leaves are luxuriant, the moss head grows and develops rapidly, the yield is high, and the fertilizer and water are large and concentrated. According to professional growers, every 100 kilograms of garlic need to absorb kilograms of nitrogen, kilograms of phosphorus and kilograms of potassium.

The amount and proportion of nitrogen, phosphorus, and potassium uptake also vary greatly at different growth stages.

Garlic fertilization technology.

Generally speaking, fertilization should be carried out scientifically and reasonably according to soil fertility and the needs of different growth stages of garlic. Grasp the principle of "light in the front and heavy in the back", not only to prevent too fast growth in the early stage, but also to avoid premature rotting of fertilizer in the later stage.

Garlic planting areas need to be deeply cultivated and harrowed to improve soil permeability, which is conducive to the activity of soil microorganisms and the transformation of soil nutrients, improves the storage capacity of soil, and is conducive to the development of roots and bulbs.

1. Apply a large amount of jointing fertilizer. Garlic is different from other crops. When the climate is normal, the garlic in the green period is generally not managed in the field, so as to avoid the occurrence of bacterial soft rot due to the sudden drop in ground temperature caused by early watering, which will affect the growth of garlic.

Therefore, the first topdressing should be carried out at the jointing stage, and the nitro compound fertilizer can be topdressed 20-25 kg per mu. The second fertilization is applied every 15-20 days, and the amount of fertilizer is about 20 kg per mu.

2. Skillful application of chemical fertilizers. Garlic enters the differentiation and sprouting stage, vegetative growth and reproductive growth are carried out at the same time, and the demand for phosphorus is strong, which is also the most critical top dressing in the life of garlic. Each mu of garlic seedlings (now tail) needs to be top-applied with 15-20 kg of high-phosphorus and high-potassium compound fertilizer, which should be dissolved first and then rinsed.

3. Top dressing outside the roots. Calcium, magnesium, iron, manganese, zinc, copper and other trace elements are necessary for the growth and development of garlic. It can be supplemented with foliar sprays or combined with pest and disease control. However, it should be noted that the properties of drugs and fertilizers are similar.

To sum up, growing garlic does have a lot of fertilization tips. If farmers want to grow high-yielding garlic, they need to master the right fertilization techniques and management methods. I hope this article was helpful to you.

Garlic is accompanied by the rise of temperature in the rejuvenation stage, and the development of plants enters the growth period, and the demand for nutrients is very large. Because most of the garlic is now planted with agricultural mulch film, the green fertilizer is usually applied according to the situation of watering back green water, 30 kg of urea plus 15 kg of potassium sulfate compound fertilizer, or 80 kg of ammonium calcium nitrate 1 mu of land. The top dressing of garlic bulging fertilizer can not be ignored, and generally we must feel that we do not have to apply fertilizer after mentioning the garlic table.

However, this period of time is the most critical time for garlic expansion, and the growth and development of garlic during the moss period is divided into vegetative growth and reproductive growth.

Garlic planting should first do a good job of sowing. First of all, when sowing garlic, choose garlic that is round and non-malignant as the base seed; The second is to do a good job of planting, knead the garlic seeds as the base seed in advance, soak them in cold water for about 2 days, and then plant them when the garlic cloves emerge with white roots. When sowing, it should be planted reasonably densely, and the interval should be manipulated around 10 cm.

Since the garlic head swells underground, it is necessary to cultivate the land resources carefully before sowing to build a relatively relaxed natural environment for it. When deep ploughing, the bottom fertilizer should be sufficient, and the bottom fertilizer before cultivating the land is best to use organic fertilizer as the main fertilizer.

Seedling fertilizer: The purpose is to promote the rapid rooting and seedling growth of garlic after germination, and improve the wintering characteristics of garlic. Generally, about 15 days after the garlic sprouts, 1 mu can be used with 5-8kg of high-nitrogen compound fertilizer, the fertilizer efficiency is very high, the bottom fertilizer is more sufficient land resources, can not apply seedling fertilizer.

Generally, 25-30 days after the application of garlic moss fertilizer, with basal fertilizer as the leading, with each other to apply phosphorus, potassium fertilizer and potassium fertilizer, 1 mu of high nitrogen compound fertilizer 15-20kg is more suitable, can achieve garlic picking and garlic expansion in the case of nutrients.

The fertilizer for planting garlic uses less urea and ammonium carbonate, which is very dangerous, because this urea and ammonium carbonate is very bad for the growth and development of garlic, it is best to use balanced fertilizer, potassium fertilizer to keep up, so it is very important to use balanced fertilizer in this aspect of fertilizer (with 3 15 that is to say 3 17) If there is a standard water-soluble fertilizer, because the water-soluble fertilizer is more soluble in water, it is washed down with water, and its effect is much better than these fertilizers that rush the granules.
