Types and application methods of foliar fertilizer

Foliar fertilizer is one of the commonly used fertilizers in crop planting, which can not only strengthen crop nutrition and prevent nutrient deficiency, but also has the advantages of fast fertilizer efficiency, high fertilizer use efficiency and small amount, which attracts many farmers to use it. So what kinds of foliar fertilizer are there? How should I use it? Come and have a look with the editor.

I. types of foliar fertilizers

1. Nutritious foliar fertilizer. In this way, the content of nitrogen, phosphorus, potassium and trace elements in foliar fertilizer is higher, mainly in order to provide a variety of nutrient elements for crops and improve crop nutrition, especially in the later stage of crop growth.

2. Regulated foliar fertilizer. This foliar fertilizer contains positions that regulate crop growth, such as auxin and hormones, mainly to regulate crop growth and development, comparing the early and middle stages of tetranuclear growth.

3. Biological foliar fertilizer. This foliar fertilizer contains microorganisms and metabolites, which can stimulate crop growth, promote crop metabolism, reduce and prevent the harm of diseases and insect pests.

4. Compound foliar fertilizer. This kind of foliar fertilizer has many kinds and functions, which can not only provide nutrition, but also stimulate growth.

2. Application method of foliar fertilizer

1. Pay attention to the spraying concentration

Different foliar fertilizers have different concentrations, and too high or too low concentrations will have different adverse effects on crops. First of all, the concentration should be prepared according to the product instructions, and then applied in a small area to ensure that the concentration is appropriate. In addition, the sprayer should be cleaned before preparation. Some foliar fertilizers can be mixed with pesticides, but some are not.

2. Rational use of foliar fertilizer

Foliar fertilizer should be reasonably selected for different crops and different growth periods, such as cotton, sweet potato, potato, rape, etc., the cuticle is thin, the fertilizer liquid is easy to permeate, and the effect of using foliar fertilizer is better, while wheat and corn, the foliar surface is smaller, the horny layer is thicker, the penetration of fertilizer liquid is more difficult, and the yield-increasing effect of foliar fertilizer is slightly worse.

3. Foliar fertilizer should be fully dissolved.

Foliar fertilizer should be fully dissolved in spraying, but some solid powdered foliar fertilizer dissolves slowly, so it should be fully stirred after adding water, and then sprayed after it is completely dissolved. If the solution is incomplete, the effect is poor when the concentration is low, and sometimes the seedlings will be burned when the concentration is high.

4. Pay attention to spraying evenly

In foliar fertilizer spraying, we should pay attention to spraying both the positive and negative sides of the leaves, spraying evenly, this is because the stomata of the leaves are distributed on both sides of the leaves, and the number of stomata on the back of some crops is more than that on the front, so it can be absorbed better.

5. Collocation

Foliar fertilizer should be combined with soil fertilization and used in combination with nitrogen, phosphorus and potassium fertilizer, which is more conducive to meet the nutritional needs of crops during the whole growth period.
