What are the types of foliar fertilizers and how to use them correctly?

From the traditional nitrogen, phosphorus and potassium compound fertilizer, to the current development of foliar fertilizer, water-soluble fertilizer, drip irrigation fertilizer, etc., agriculture has also developed from traditional cultivation to modern ecological agriculture, and agriculture has been continuously surpassed by modern science and technology.

Foliar fertilizer, literally understood as the fertilizer applied by crop foliar fertilizer, from a scientific point of view, it is divided into four categories: inorganic nutrient foliar fertilizer, plant growth regulator foliar fertilizer, biological foliar fertilizer, compound foliar fertilizer, etc., and the four types of foliar fertilizer are divided into special foliar fertilizers according to the growth characteristics of various crops, such as vegetable foliar fertilizer, melon and fruit foliar fertilizer, medicinal foliar fertilizer, wheat foliar fertilizer, corn foliar fertilizer and so on.

The nitrogen, phosphorus and potassium elements contained in the inorganic nutrient foliar fertilizer can quickly supplement the nutrients required in the middle and late stages of crop growth, and improve the yield and quality of fruits. The foliar surface of plant growth regulator can regulate crop growth and enhance crop stress resistance. Biological foliar fertilizer can promote crop metabolism and reduce the occurrence of pests and diseases. Compound foliar fertilizer is a general-purpose fertilizer for crops and is suitable for most crop growth needs.

When planting crops such as wheat, corn, soybeans, peanuts, fruit trees, etc., adequate fertilizer should be applied first so that nutrients can be absorbed during the growth of the crop. Foliar fertilizer, its role is in the middle of crop growth, root nutrition away from the roots of crops and do, acting on crop roots, and affect production, foliar fertilizer is the best way to solve this problem, it is liquid fertilizer sprayed directly on the leaves, under the action of light and tree respiration, directly convert foliar nutrition into the components required by plants, in order to achieve the nutrients directly delivered to the parts required by the plant, if the person is sick, the method of hanging needle will be directly transported to the lesion through the blood vessels, in order to achieve the effect of keratinization treatment.

Foliar fertilizer plays an important role in the cultivation process, and its biggest feature is the rapid absorption of nutrients, which are directly absorbed into the plant through the leaves. Of course, foliar fertilizers are highly targeted and can meet many of the special needs of crops. In the planting process, the yield and quality can be improved, and the fertilizer utilization rate can be improved.

All kinds of foliar fertilizers have their own characteristics and functions.

Today, we will mainly talk about the characteristics of the use of foliar fertilizers. Foliar fertilizer, fast nutrient absorption, good fertilizer efficiency. After the soil is fertilized, various elements in the soil are easily absorbed by the soil.

After the soil decomposes, nutrients are absorbed by the roots and transferred to the leaves through vascular bundles. The shipping speed is too slow. Foliar fertilizers spray nutrients directly onto the leaves.

Various nutrients can be quickly absorbed by the leaves, directly enter the plant, and participate in the metabolism of the plant and the synthesis of organic substances. The biggest feature of foliar fertilizer is that the fertilization time is relatively short, which can allow plants to absorb nutrients in the shortest time and ensure the growth of plants. During the planting process, both root fertilization and foliar fertilization are targeted.

Because soil fertilization takes a certain amount of time to transform nutrients before they can be absorbed by plants, it cannot alleviate the lack and demand of plants for nutrients in time. At this time, foliar fertilizer can provide nutrients and various trace elements according to the growth of the plant. Foliar sprays can be effective in improving the condition when plants are deficient in nutrients.

Foliar spraying, which has the irreplaceable advantage of root fertilization, can solve many special problems in plant growth.

It is conducive to promoting the nutrient absorption of crops, ensuring the amount of fertilizer, improving the yield of crops, and ensuring that the particles of the soil will not affect the growth of crops. According to the growth of crops, reasonable use should be carried out, the amount of foliar fertilizer should be controlled, and the use of foliar fertilizer should be paid attention to.

It can improve nutrients, better help crops grow, can have the effect of preventing insect pests, can prevent diseases, and can also improve the immunity of crops. The method of use is to mix foliar fertilizer and water in the same proportion, and then spray it on the surface of the crop through some instruments.

It can allow plants to absorb nutrients very quickly, avoid the loss of nutrients, reduce costs, and use very little. Dilute the foliar fertilizer first, then spray evenly on the front and back of the foliage, but not too much.

In salinized soils, soil fertilizer is likely to increase the concentration of soil substances and aggravate soil salinization.

1. Fill the root topdressing is not enough.

When it is inconvenient to fertilize the roots of crops, such as in the middle and late stages of crop growth and development, the charm of rhizomes declines, and the ability to absorb fertilizer decreases. Or when the soil natural environment is poor for crop growth and development, such as too much water, drought, soil acidity, too alkaline, resulting in crop rhizome digestion and absorption blocked, and crops must quickly resume normal growth and development, if the root application method can not immediately achieve the crop must, only the use of leaf spray fertilizer, can quickly supplement vitamins, to achieve the need for crop growth and development.

2. Quickly replenish vitamins.

In the process of crop growth and development, crops have shown some symptoms of inattention of trace elements, because the selection of soil fertilizer must take a certain amount of time for nutrients to be digested and absorbed by crops, and can not immediately alleviate the symptoms of crop deficiency. At this time, foliar fertilization can make nutrients quickly enter the plant cells according to the foliar surface and deal with the problem of nutrient deficiency.

3. Make full use of fertility.

Some chemical fertilizers such as phosphorus, iron, manganese, copper, zinc fertilizer, etc., if applied as roots, are easy to be fixed by the soil, which endangers the actual effect of use, and the selection of leaf spraying fertilizer is not easy to be limited by soil standards. For example, some fruit trees and other deep root crops have a relatively small intake of some trace elements, if the traditional fertilizer application method cannot be applied to the rhizome digestion and absorption position, and can not exert its fertility, while leaf fertilizer spraying can obtain good practical results.

4. Appropriate economic development.

A variety of nutrients are indispensable nutrients in the growth and development of crops, but the application amount is very small, such as molybdenum fertilizer, the application amount of 1 mu is only a few tens of grams, if the root application method is not easy to apply evenly. Only by using leaf spraying fertilizer can we achieve reasonable economic development. According to the analysis and calculation, the use rate of boron fertilizer on the leaves of general crops is times that of basal application.

From the perspective of economic benefits, leaf fertilizer spraying is more suitable than root application.

5. Alleviate environmental pollution to the soil.

The use of base fertilizer for soil is very easy to lead to the accumulation of phosphate in surface water and vegetables and fruits, which has adverse effects on health. About 75% of the phosphate digested and absorbed by people is in vegetables and fruits, if the method of foliar fertilization is used to moderately reduce the amount of soil fertilizer, it can reduce the phosphate composition in the body of green plants and the residual mineral nitrogen in the soil.

In salinized soils, soil fertilizer is likely to increase the concentration of soil substances and aggravate soil salinization. The use of foliar fertilization countermeasures not only reduces the amount of fertilizer application, but also reduces the environmental pollution of soil and water resources, which is a reasonable fertilizer technology that kills two birds with one stone.

Foliar fertilizer can supplement nutrients to the foliar surface of plants, while root fertilizer can ensure the healthy growth of the root system and avoid insect pests.

The efficacy of the two and the method of use are very different. Root fertilizer is mainly sprayed on the roots of plants, and foliar fertilizer is mainly sprayed on the foliage, this fertilizer can make the leaves grow well.

I think the role of leaf fertilizer is that the main function is to make the leaves grow fuller, mainly for some vegetable crops, and the role of root fertilizer is mainly to make the root system grow more developed, mainly for some fruit trees.

Foliar fertilizer, as the name suggests, is a fertilizer sprayed on the foliar surface to promote plant absorption, according to the different product names and effects, Kunlun biological foliar fertilizer, can be divided into these types:

1. Nutritional and disease-resistant foliar fertilizer: Kunlun Feng "Disease Resistance and Yield Increase"**, Challenge King Humic Acid Nutritional Regulator, mainly using biological factors to promote photosynthesis, enhance immunity, disease resistance and stress resistance nutrition to regulate production and disease resistance.

2. Fruit and vegetable fruit yield increase foliar fertilizer: Jin Tailiang, colorist, 12 elements, using organic chelated titanium, using multi-element chelating technology to produce a variety of medium and trace elements, which can comprehensively supplement a variety of nutrients. Improve the stress resistance of fruit trees, prevent diseases and prevent sunburn.

Foliar fertilizer is different according to the formula, there are many types, there are single effects, there are also compound effects, the core raw materials of the product are different, and the effect is not the same. At present, there are about 10,000 brands of foliar fertilizer on the market in China, and in recent years, farmers have reported that the effect is better than that of black essence, pure humic acid foliar fertilizer, and the effect is very good.

Foliar fertilizer has a large number of elemental fertilizers, such as nitrogen fertilizer urea, ammonium sulfate, ammonium nitrate, etc., phosphate fertilizer superphosphate, heavy superphosphate, etc., potassium fertilizer potassium sulfate, potassium chloride and binary compound fertilizer potassium dihydrogen phosphate, potassium nitrate, etc.; Medium elements, such as calcium fertilizer, calcium nitrate, magnesium fertilizer, magnesium sulfate, trace elements, such as zinc sulfate, ferrous sulfate, manganese sulfate, copper sulfate, ammonium molybdate, boric acid and borax, etc., as well as various amino acids. In recent years, a large number of new foliar fertilizers have been developed and developed, mostly compound foliar fertilizers, some are based on macroelements, some are based on trace elements, some are based on amino acids, some are organic and inorganic compounds, and there are also nutrients plus plant growth regulators.

Hello: First: It is a nutrient liquid foliar fertilizer, which contains a variety of nutrients needed for plant growth;

Second, it is a hormonal liquid foliar fertilizer, which contains hormones that can regulate plant growth;

Third: it is a mixed liquid foliar fertilizer, which contains a variety of nutrients and some plant growth hormones.

1. Foliar fertilizer is roughly divided into three types: vegetative, functional and mixed according to function.

The vegetative type is that it can supplement nutrients for crops, such as macro-element foliar fertilizer, aminomycin foliar fertilizer, medium and trace element foliar fertilizer, single element foliar fertilizer, etc.;

Functional foliar fertilizer, also known as hormone foliar fertilizer, is mainly used to regulate plant growth and achieve the purpose of increasing yield, such as etc.;

A hybrid is a mixture of foliar fertilizers that contain nutrients, have a regulating effect, or have other effects.

Second, whether the effect of foliar fertilizer is good.

Foliar fertilizer works well!

The difference between foliar fertilizer and root fertilization is that foliar fertilization is firstly convenient, secondly fast-absorbing, and thirdly, it can quickly replenish nutrients for crops when the roots are degraded or their activity is reduced.

Therefore, the rational use of foliar fertilizer can have a good effect on crop yields!

There are many types of foliar fertilizers, including foliar fertilizers with multiple elements, and foliar fertilizers with high phosphorus and high potassium.

Types of foliar fertilizers: amino acids, humic acid. Trace element. Luofeng Wang medicinal fertilizer. Yiyou liquid fertilizer.

Rare earth foliar fertilizer quality***.

Foliar fertilizer is sprayed.

Personally, I feel that foliar fertilizer is a kind of Liu, which is similar to the same, mainly for the absorption of crop leaves, and the composition is not much different.

<> foliar fertilizer can be generally divided into four categories according to its function and function, namely vegetative foliar fertilizer, adjusted foliar fertilizer, biological foliar fertilizer, and compound foliar fertilizer. Foliar fertilizer is different from plant growth regulators, it is a nutrient made by combining nitrogen, phosphorus, potassium, iron, zinc, manganese and other elements, which can not only supplement nutrients for crops, but also make crops grow rapidly.
