What are the role of potassium fertilizers?

one,The role of Potassium fertilizer

Applying Potassium fertilizer can promote the photosynthesis of crops, promote the results of crops and improve the ability of crops to resist cold and disease, thereby improving agricultural output.Potassium exists in the form of free potassium ions in the plant, which can promote the metabolism of carbohydrates and nitrogen; control and regulate the activity of various mineral nutrients; activate the activity of various enzymes; control nutrients and water transportation; maintain the cells of cells; maintain the cells of cellsInternal pressure to prevent the plant from withering.

1. Promote the activation of enzymes

The activation of enzymes is one of the most important functions in potassium in plant growth. It has been found that potassium is the activator of more than 60 enzymes.therefore.Many of the metabolism processes in potassium and plants are closely related, such as: photosynthesis, breathing, and carbohydrates, fat, protein synthesis, etc.

2. Promote the transportation of photosynthesis and optical products

Improve photosynthetic efficiency; regulate the opening and closing of the gas holes, control the entry and exit of Co and water; Promote the synthesis of carbohydrates and accelerate the flow of photosynthesis products.

3. Promote protein synthesis

The intake and operation of the key ingredients of protein synthesis; is closely related to the synthesis process of protein.

4. Enhance the anti -reverse nature of plants

Potassium can reduce the soluble amino acids and monosaccharides in the body, increase cellulose, and thick cell walls; potassium accumulates the accumulation of crop root system to produce permeable pressure gradients to enhance water absorption; potassium can cause the crop blade air to close the air pores to prevent water from water prevention loss when drought and water deficiency.EssenceTherefore, potassium can enhance the ability of disease resistance, cold, drought resistance, anti -falling and salt resistance of crops.

5. Improve the quality of crop products

increase the protein content of grain crops, the crude fat and palm acid content of oil crops, the content of starch and sugar content of potato and sugar crops; increase the length, strength, and fineness of the fiber crops and cotton fiber;The content of vitamin C; improving the shape, size, color and flavor of fruit vegetables, and enhance their storage resistance.

2. agricultural application of potassium Fertilizers

When crops lack Potassium fertilizer, they will get "cartilage disease" and easily fall down. They are often called "quality elements" by germs of pests.Its role in the quality of crop products is: can promote the use of nitrogen better, increase the content of protein, and promote the production of sugar and starch;Beautiful color; increase the oil content of oil crops and increase the content of vitamin C in fruits; Accelerate the maturity of fruits, vegetables and other crops to make the maturity period consistent;storage and transportation period; Add the strength, length, and fineness of cotton and hemp crops, and the purity of the color.

What are the types of potassium Fertilizers?

Potassium fertilizer can be divided into two categories: industrial Potassium fertilizer and other potassium Fertilizers.Among them, Potassium fertilizer of industrial industrial is: potassium sulfate, potassium chloride, potassium nitrate, potassium phosphate, potassium magnesium Fertilizer, potassium and calcium Fertilizer.Other potassium Fertilizers include plant ash, kiln ash Potassium fertilizer, organic Potassium fertilizer, etc.

1. Potater sulfate Fertilizer

Potater sulfate Fertilizer generally refers to potassium sulfate magnesium Fertilizer.Contains K2O 50%to 52%, easy to dissolve in water, physiological acidic Fertilizers.After the soil is applied, the potassium is ionic, and part of the plants are directly absorbed and utilized, and part of it is exchanged with the cation on the soil gum, and calcium sulfate and sulfuric acid are generated.Therefore, after a large amount of potassium sulfate is applied to prevent soil plate knots, on the one hand, Organic fertilizer can be applied. On the one hand, lime can be applied to neutralize acidity.

The role of potassium sulfate Fertilizers is based on base Fertilizer and topdressing.Because potassium moves in the soil, it is more suitable for basic Fertilizer.When topdressing, we must apply the dense layer of the crop system.Potassium sulfate is particularly effective for sulfur crops such as the family. Due to its high price, farmers can choose potassium chloride as much as possible in addition to avoiding chlorine crops.

2. Potassium chlorine

Contains K2O 50%~ 60%, easy to dissolve in water, fast Fertilizer, physiological acid Fertilizer.Calcium chloride will be generated in a neutral soil, causing calcium loss; calcium carbonate in lime soil reacts with potassium chloride, which can neutralize and release effective calcium; hydrochloric acid will be generated in acidic soil.Enhance the soil acidity, increase acid and aluminum poisoning, and use lime and Organic fertilizer.

Potassium chloride can be used as base Fertilizer, topdressing, not suitable for planting, and should not be applied to avoid chlorine -alkali -alkali land.Cotton -and -linen fiber crops can improve products and quality.

3. Potassium

It contains 13.5%nitrogen nitrogen and 46%of potassium containing potassium. It is a chemical neutral and physiological neutral Fertilizer. It has good water -soluble and is applied for a long time to cause soil acidification.It is suitable for the expansion of vegetables and fruit trees to the early stages of coloring, which can promote the expansion of pulp cells.Because it contains nitrate nitrogen, it is not recommended to use it in the later stages of coloring, which is easy to cause returning to green.

4, grass and gray

It contains a variety of plant gray elements, including: potassium, calcium, phosphorus, magnesium, sulfur, iron, silicon and other plant nutrient elements.Among them, potassium exists in the form of potassium carbonate, potassium sulfate, and potassium chloride, and phosphorus exists in the form of weak acid -soluble phosphorus.It belongs to alkaline Fertilizers.Do not mix with ammonium nitrogen Fertilizers.It should not be mixed with organic Fertilizers such as Fertilizer, fecal urine, and can easily cause volatilization of nitrogen.Sodium and chloride ions in the plant ash in saline -alkali land are easy to increase soil salt as Fertilizer.

Herbal ash can be used as base Fertilizer, topdressing, and planting Fertilizer.The amount of Fertilizer Fertilizer is 50 ~ 100 kg/mu, as the amount of Fertilizer is 50 kg/mu. It can be mixed with 2 to 3 times before application.Nutrition solution is sprayed with leaf surface.

5. Phosphorus and Potassium fertilizer

The potassium ore containing (phosphorus) is broken to about 100 mesh, and the balance of the sieve is less than 15%.It is an auxiliary material, and its proportion is mineral powder: auxiliary materials = 85 95: 2.2 5; the biochemical reaction is performed in the reactor after the ingredients.After the reaction is completed, the granules can be made according to the distribution ratio.

6, potassium dihydrogen phosphate

After the potassium dihydrogen phosphate melts, it is a transparent liquid, and it is opaque glass -shaped after curing.Potassium dihydrogen phosphate is an efficient phosphorus and potassium Compound fertilizer, which contains about 52%of phosphorus and about 34%of potassium.Potassium dihydrogen phosphate is suitable for various types of economic crops, including food, fruits, vegetables, etc., which can generally be used before and after flowering, color period, and fruit picking.After the use of potassium dihydrogen phosphate, it has a significant increase in crop yield, improvement of crop quality, and improving crop resistance and disease -resistant pests.
