How to use fertilizer when garlic is in the vigorous growth period?

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.

In summer, it is growing at this time, and it needs more nutrients and trace elements, so it is necessary to fertilize reasonably according to the actual situation.

It should be spring. It is definitely necessary to increase the use of fertilizers, which can be appropriately supplemented with organic fertilizers, and foliar fertilizers should also be used.

In spring, at this time, it is necessary to grow rapidly, fertilizer is needed, and fertilizer needs to be applied scientifically according to the growth of plants.

It is easy to use good pubic root maggots, so when using farm fertilizer, you must not use raw fertilizer, you must use cooked fertilizer; Regularly pour white vinegar into the garlic field to repel insects, and after using white vinegar, about a day or two, you need to sprinkle some plant ash to neutralize the slight acids in the soil.

If you can't use urea for planting, you can use nitrogen, phosphorus and potassium compound fertilizer + plant ash.

Planting garlic should be based on the fertilization principle of organic fertilizer, supplemented by chemical fertilizer, mainly base fertilizer, and supplemented by top dressing. Base fertilizer: Before sowing, the base fertilizer is applied in combination with the cultivator, and the farmhouse fertilizer is combined with chlorine-based compound fertilizer, zinc sulfate, etc.

Jointing fertilizer: Nitro compound fertilizer is applied at the jointing stage, and the second top application is applied at an interval of 15-20 days. Divide fertilizer:

In the differentiation stage of moss, high phosphorus and high potassium compound fertilizer was applied. Off-root fertilization: Choose a sunny day before 11 a.m. or after 4 p.m.

In the process of fertilization, be sure to use farmhouse fertilizer, do not use fertilizer bought outside. And it is necessary to water the plants frequently and more often to prevent the occurrence of pests and diseases. In the process of fertilization, do not overdose, to the right amount, if you are afraid of this kind of problem, be sure to use a professional fertilizer machine to fertilize, there are many families do this.

At this time, it is necessary to choose the right time for fertilization, and then to choose the right fertilizer, at this time you can choose phosphate fertilizer, nitrogen fertilizer, farmhouse fertilizer or organic fertilizer.

1. Base fertilizer should be applied before sowing, and the fertilizer composition is organic fertilizer, phosphate fertilizer, potassium fertilizer, etc.

2. Top dressing is carried out at the seedling stage to supplement the lack of base fertilizer.

3. Carry out the second top dressing during the growth period to make the garlic grow more vigorously.

4. After harvesting, fertilizer should also be applied once to ensure that the garlic head is expanded.

The most suitable fertilizer for planting garlic is potassium fertilizer, which is added once every two days, in batches, preferably sprinkled on the roots, and then watered a little, so that the absorption is faster.

1. Selection and preparation of base fertilizer. Before sowing, basal fertilizer can be applied to garlic per mu according to the following standards:

1) Organic fertilizer (slag fertilizer, pig or cow manure should be fermented and cooked) 60 to 50 kg of loo or cake fertilizer;

2) 50 kg of ammonium bicarbonate;

3) 50 kg of superphosphate;

4) potassium chloride 15 kg;

5) Zinc sulfate 1 to 5 kg.

The basal fertilizer selected above can be applied alone before sowing, or mixed with organic fertilizer). In addition, 60 to 65 kg of nitrogen, phosphorus and potassium tri-element compound fertilizer containing 15 per mu of garlic can also be used as base fertilizer before sowing. The application of basal fertilizer according to the above method can promote the development of garlic root system and improve the stress resistance function of garlic.

2. Selection and preparation of top dressing at seedling stage.

When garlic grows 3 to 4 true leaves, in addition to topdressing urea 8 to 10 kg per mu, 200 grams of potassium dihydrogen sulfate, or 250 grams of zinc sulfate, or 50 grams of green fenwei, or 40 grams of Songgang Lusheng, or 200 grams of Tianrun foliar fertilizer (the above foliar fertilizer can be any one) with 60 kg of water in the early, middle and late stages of garlic growth can be sprayed once, which can promote the early maturity of garlic and improve the yield and quality of garlic.

What kind of fertilizer do you use, really.

Garlic topdressing has skills, topdressing in these periods, good growth and high yield, respectively, seedling stage, overwintering period, regreening stage, garlic vine growth period, garlic growth period.

1. Seedling period - seedling fertilizer: garlic seedling stage due to the small body and frailty, top dressing should not be too violent, the main ascension to the royal to lay a good foundation, cultivate strong seedlings, so this period of top dressing is also called "seedling fertilizer" or "seedling fertilizer"."。

Top dressing needs to be carried out according to the growth of seedlings, if the growth is good, because of the bottom fertilizer and garlic nutrients, you can not use top dressing to prevent vigorous growth before winter. If the seedlings are weak, they need to be topdressed, and thin human manure can be applied, and if chemical fertilizers are used, 10-15 kg of ammonium sulfate per mu, or 5-8 kg of urea, should be applied with water to promote the development of seedlings.

2. Overwintering period - overwintering fertilizer: With the progress of time, the weather gradually becomes cooler, the underground stems of garlic also begin to differentiate, and the growth and development have slowed down, so it is necessary to start the overwintering management of seedlings.

Seedlings generally need to grow 4-6 true leaves to overwinter in a strong seedling posture before winter, at this time need to be topdressing again, called "overwintering fertilizer" or "wax fertilizer", which can not only provide nutrients for seedlings in winter, but also have the effect of keeping warm, in order to facilitate the safe wintering of seedlings, and at the same time can promote the accelerated development of underground stems, more branches, and also have a positive effect on the early return to green in the coming year.

3. Rejuvenating period - regreening noisy rock fertilizer: After the beginning of spring in the coming year, the temperature gradually rises, about the spring equinox to Qingming, when the temperature reaches about 7 degrees, the garlic ends its winter dormancy and begins to return to green trees. At this time, the garlic clove has finally ended its historical mission, and its nutrients have been used up.

Begin to "withdraw the mother", the garlic cloves gradually dry up, and the baton for the garlic to continue to supply nutrients is handed over to the hands of the root system, which requires a short adaptation process, which will make the nutrients ** in a weakening period of green and yellow, and the leaves of garlic appear yellow tips and are dry. At the same time of watering the "green water", the "green fertilizer" was applied, and ammonia fertilizer was the main one.

4. Garlic vine growth period - pumping Ling fertilizer: after the completion of "retiring mother", the flower buds of garlic are differentiated, the garlic tomb grows rapidly, the scale buds germinate, the bulb begins to form and expand, the growth of garlic is in the parallel period of garlic tomb and garlic head, and when the garlic tomb is pumped, all the leaves of garlic grow completely, and the garlic head also develops about half of the overall volume.

The root system of garlic has fully taken over the task of over-nutrient **, and the fertilizer absorption performance is excellent, and the demand for nutrients is strong, forming a peak period. 10 kg of urea and about 30 kg of potassium sulfate compound fertilizer were applied per mu to promote the rapid pumping of garlic vines.

5. Garlic growth period - change - swelling fertilizer: after the garlic vine is harvested, the focus of nutrients will turn to garlic, the weight of garlic increases rapidly, and the diameter is gradually growing. However, the top dressing should be carried out before the garlic vine is harvested, so that the garlic can be used immediately after the garlic tomb is harvested, and if the top dressing is carried out after the garlic tomb is harvested, it is easy to induce the plant to be greedy for green, resulting in a reduction in yield.

Top dressing is mainly available ammonia fertilizer, 5-10 kg of nitrogen and potassium compound fertilizer or 5 kg of urea per mu, which needs to be controlled, not excessive, to avoid the young buds of garlic cloves to return to green, and start to grow leaves again and consume nutrients.
