Is it necessary to use fertilizers and pesticides in the cultivation of garlic? Why?

Garlic dry tip yellow leaves, is a problem that many growers will encounter every year, almost every piece of land has this situation, these days some farmers say that garlic has dry tip yellow leaves, because after the cooling, the leaves have a slight frost damage.

In general, potassium dihydrogen phosphate and brassinin need to be sprayed to prevent low-temperature frost damage, and it can also be mixed with fungicides when diseases occur. In addition, there is another situation that cannot be ignored, that is, caused by lack of fertilizer.

Garlic needs a lot of fertilizer, but the root system is weak, and it needs to be fertilized in stages, which is a scientific fertilization method. Some farmers do not use seedling fertilizer after the emergence of garlic seedlings, and they do not top fertilizer when they water overwintering water in winter, and now they can only wait until the garlic returns to green.

When the growth of garlic is relatively weak before winter, some fertilizer can be used when watering overwintering water to supplement nutrients, and at the same time, it also prevents the growth of garlic from being affected by delaying watering and fertilizer when the temperature is low after spring.

If the garlic has not been fertilized in the early stage of growth, then the application of regreening fertilizer should be paid attention to after the year to promote the regreening and later growth. Now farmers are more entangled with urea or nitrogen, phosphorus and potassium compound fertilizer, which fertilizer has a better effect?

After the garlic returns to green, the leaves enter the vigorous growth period, and the nutrients required during this period increase, and they all rely on the nutrients absorbed. Among the three elements of nitrogen, phosphorus and potassium, nitrogen deficiency had the greatest impact on yield, followed by phosphorus and potassium fertilizers. In the top dressing, nitrogen fertilizers should be the mainstay, such as urea, ammonium sulfate and other fertilizers to top dressing.

The specific phosphorus and potassium can be decided according to the situation of the base fertilizer.

In some garlic plots, the bottom fertilizer is made of farmhouse fertilizer and urea, the nitrogen content is more, and there is no top dressing, this situation is in the first top dressing, in addition to supplementing nitrogen fertilizer, there is also appropriate top dressing phosphorus and potassium fertilizer, or with high nitrogen, low phosphorus and low potassium compound fertilizer, 30-40 catties per mu. Dissolve the compound fertilizer in water, and then apply it topdressing, the utilization rate will be higher, otherwise half of the fertilizer may be on the mulch, and a lot of waste will be wasted.

The bottom fertilizer nutrient balance and relatively sufficient plots, urea or ammonium sulfate are used in top dressing, with high nitrogen content, garlic can be quickly absorbed, about 30 catties per mu, and applied with water. In general, ammonium sulfate is superior to urea and has a high absorption rate. In fact, in addition to nitrogen fertilizer, add some potassium fertilizer, garlic growth will be better, about 10 catties of potassium sulfate can be used per mu, potassium chloride is not recommended.

With more input, the yield of garlic is not necessarily high. But when we apply fertilizer, we should choose according to the needs of crop growth. Garlic topdressing is not only a choice to follow the trend, but also according to the amount of base fertilizer, garlic growth to decide, in addition to nitrogen, phosphorus and potassium, some calcium, magnesium, iron and other trace elements should also be reasonably applied.

Speaking of garlic, I believe that friends from rural families will grow it. It is a very common ingredient, garlic is a kind of food that people are very familiar with, there are many friends who love to eat garlic, garlic not only has a good value, but also can protect the liver to prevent diseases, the effect is very many, not only can be used as a seasoning, but also can be used as medicine, is a famous edible and medicinal plant.

So do you know what kind of base fertilizer is good for garlic? What is the application method of basal fertilizer? Today we will talk about it briefly.

Organic fertilizer should be the main base fertilizer of garlic, organic fertilizer usually refers to ring fertilizer, chicken manure, duck manure, manure, compost, cake fertilizer, etc. The adequacy of basal fertilizer is directly related to the commercialization of garlic bulbs and the overwintering performance of plants. Therefore, the production of garlic in Chaga should be applied with sufficient base fertilizer.

Potash fertilizer can be applied with the cultivated land when cultivating the land, and it can be turned into the ground.

The application method of garlic-based fertilizer is generally to apply half of the organic fertilizer before ploughing the land, evenly sprinkle it on the soil surface, and turn the fertilizer into the ground in combination with the cultivated land; For the other half, when sowing, the focus is on furrow fertilization, mixing fertilizer and soil, and then sowing the seeds.

After application, it is combined with soil preparation to mix the fertilizer and soil evenly. The application should be shallow, concentrated or layered. Part of it can be applied before cultivated land, the other part can be applied when planting garlic after cultivated land, and it can also be shallow applied to 6 cm 10 cm underground after land preparation, so as to facilitate the absorption and utilization of seedlings, cultivate strong seedlings, and improve the utilization rate of phosphate fertilizer in the current season.

Potash can be applied along with arable land to the soil.

The production of 1000 kg of garlic requires the absorption of kg of nitrogen, kg of phosphorus, kg of potassium. Appropriate application of sulfur fertilizer can improve the yield and quality of garlic and garlic sprouts. Nutrients such as copper, boron, and zinc have a significant impact on garlic yield.

Garlic sprouting period is long, top dressing, from scale bud flower bud differentiation to sprouting is the same period of vegetative growth and reproductive growth, that is, into the vigorous growth period.

The chicken fertilizer of garlic should be mainly organic fertilizer, which usually refers to chicken manure, duck manure, compost, cake fertilizer, etc.; First of all, it is necessary to sprinkle and strip application, use the simplest method to evenly sprinkle on the soil surface, pat it and then carry out layered fertilization and hole application, which is very recommended for crops cultivated with plastic film cover.

Garlic is a very easy plant to live, so use the most basic acorn base on the side of the base fertilizer, when using the base fertilizer, first of all, mixed with other soil in front of a balance, and then put the garlic seeds into the soil, so as to ensure the development rate of garlic seedlings.

The base fertilizer of garlic is mainly organic fertilizer, including chicken manure, duck manure, manure, compost, cake fertilizer, etc.; Generally, half of the organic fertilizer is input before the cultivated land, evenly sprinkled on the soil surface combined with the cultivation of Yuzhou land, the fertilizer is turned into the ground, and the other half is destroyed and concentrated for furrow application when sowing the seed, and the fertilizer is mixed and then sown.

First of all, let's understand the need for fertilizer for garlic, the amount of fertilizer required for garlic is very large, and the necessary level of organic fertilizer for different growth periods is different, and the farmers must carry out fertilizer scientifically and reasonably. The amount of nutrients used by garlic in the germination period is not too large, and the key at this moment is to give nutrients with the help of garlic mother, but until the garlic enters the seedling stage, the effect of garlic mother is getting smaller and smaller, and finally the nutrients disappear. In order for garlic to grow, it must absorb nutrients from the soil layer.

At this moment, it is necessary for the planters to do a good job of fertilizing immediately. After that, the growth of garlic has entered the scaly bud differentiation stage, which is also a critical period for the growth and development of garlic, and the digestion and absorption of organic fertilizers are also particularly large. In the middle and late stages, the reproductive growth and vegetative growth of garlic are carried out simultaneously, and the amount of fertilizer required at this time should be a link in the case of garlic growth and development, and after the completion of this link, it will enter the middle and late stages of garlic growth and development, and the fertilizer demand in the middle and late stages is small, and farmers only need a little fertilizer.

How do I start fattening?

Bottom fertilizer: the key to organic fertilizer is dominated by organic fertilizer, according to the soil organic matter of each place before garlic planting, generally 1 mu can be fermented with 3500kg of organic fertilizer, and the other is matched with the application of some organic fertilizer, which can be 1 mu with 50kg of calcium dihydrogen phosphate and 30kg of garlic special fertilizer.

Fertilization seedling fertilization: seedling fertilization is generally carried out two weeks after garlic germination, at this time, fertilization can promote the rapid growth of garlic roots, promote garlic to improve the level of winter, but for some soil organic matter is relatively high, garlic growth and development of good land can reduce the fertilization or do not carry out the fertilization work. At this moment, the key to the growth and development of garlic must be base fertilizer, and fertilization can be done with high-nitrogen compound fertilizer, and the dose of one mu is about 6 kg.

Back to green fertilizer: After the temperature slowly rises in spring, but the harm of good luck temperature standards across the country, there are some differences in the top dressing time of green fertilizer, and fertilization is generally carried out around the beginning of spring every year. Fertilization in this link is also usually basal fertilizer, which can be about 8 kg of compound fertilizer for 1 mu of top dressing.

Fertilization at the budding stage: garlic into this link is the most abundant link for chemical fertilizer digestion and absorption, and this fertilization has a vital direct impact on the growth of garlic in the middle and late stages. Generally, in the case of garlic seedlings gradually revealing tassels, fertilization is gradually carried out, 1 mu of topdressing urea solution is about 10 kg, and then with the application of ammonium sulfate compound fertilizer within 30 kg.

Fertilization in the middle and late stages: The fertilization is generally carried out after the garlic seedlings are picked, at this time the garlic seedlings have already been picked to more than 50%, at this time, ammonium sulfate compound fertilizer can be used to carry out top dressing, and the dose of one mu is about 20kg. The above is related to the garlic growth process on the fertilizer, naturally want to make the garlic production good, in addition to the fertilizer problem should be paid attention to, but also scientific and reasonable seedling, effective ploughing, prevention of diseases, and need to pay attention to scientific and reasonable watering and other problems.

Garlic is a fertilizer-loving plant, and it needs to be fertilized in time during the growth period, but it also needs to be fertilized according to the law of fertilizer needs for garlic growth, so as to give the best play to the role of fertilizer. The nutrients contained in organic fertilizer are relatively comprehensive, which plays an irreplaceable role in the cultivation and growth of garlic, which is conducive to the development and formation of bulbs, and can also increase the loose air permeability of the soil, creating a good soil environment for root growth and bulb expansion.

I recommend ternary compound fertilizer because the soluble fertilizer has a balanced content of nitrogen, phosphorus and potassium, which allows garlic to have sufficient nutrients to grow.

I recommend using urea because this fertilizer is high in nitrogen and is most helpful for rhizome growth.

1. The top dressing of garlic is generally based on nitrogen fertilizer, and nitrogen, phosphorus, potassium fertilizer and various elements should be applied together when needed, which is conducive to the normal growth and development of garlic, and is conducive to promoting the absorption and utilization of nutrients and improving quality. Nitrogen fertilizer had a significant effect on garlic yield.

When topdressing garlic with nitrogen fertilizer, attention should be paid to the possible adverse effects. In addition, according to the experiment, the effect of nitrogen fertilizer topdressing is closely related to the size of garlic cloves, and the smaller the garlic cloves, the greater the yield increase of nitrogen application. Therefore, when using small cloves of garlic for seed garlic, the application rate of nitrogen fertilizer should be appropriately increased.

2. Topdressing of phosphorus fertilizer and potassium fertilizer in garlic can improve the balanced absorption and utilization of nitrogen fertilizer, promote the growth and development of garlic, and increase the yield of garlic sprouts and garlic heads. In the later stage of garlic, not only nitrogen fertilizer should be applied, but also phosphorus and potassium fertilizer should be applied, and nitrogen, phosphorus and potassium fertilizer should be combined according to 2:1:

1 proportional application, or compound fertilizer application. This study is beneficial to prevent premature leaf senescence and promote the transport of leaf nutrients to bulbs in the later stage of garlic, and can significantly increase the yield of garlic sprouts and garlic heads.

3. The topdressing period can generally be divided into topdressing before wintering, topdressing during the regreening period, topdressing during the long-term extension of garlic sprouts and topdressing during the growth period of garlic.

Of course, you can apply farm fertilizer, but farm fertilizer must be fermented at high temperature to rot before it can be yo, not rotten farm fertilizer will cause damage to garlic, slightly will make the garlic root system with a trillion to absorb the nutrients, serious will cause burn rhizomes, rotten Zen sell roots, so that the growth of garlic is weakened, and even the seedlings will wither. ”

I think of course it is, because farmhouse fertilizer is not only nutritionally balanced, but also mild in fertility, and it is not easy to burn seedlings.

In the process of planting garlic early, applying farm fertilizer to garlic helps garlic grow. This can make the garlic grow more powerful, and it is a natural pollution-free cultivation method.
