What is the Fertilizer of slow release Fertilizer

Slow -efficient Fertilizer is also called long -acting Fertilizer and slow -release Fertilizer. The compounds or physical states presented by these Fertilizers can be slowly released for a period of time to continuously absorb and use the plant.The dissolution of soil solution must be dissolved after a short -term transformation before it can be seen. However, Fertilizer effects are relatively long. The release of nutrients in Fertilizers is completely determined by natural factors and has not been manually controlled.

The role of slow release Fertilizer

Slow -efficient Fertilizer is often used as base Fertilizer, and the main function is to supplement the nitrogen element required during the growth of plant.

How to use slow release Fertilizer

To avoid the root system, just sprinkle around the crops (plants).There are mainly the following methods:

1. Soil mixed: Slow -release Fertilizer can be mixed directly with the soil.Mix the appropriate amount of mild release Fertilizer and potted soil and plant it.

2. Dig pits and Fertilizer: mix the mixed -release Fertilizer into a small amount of potted soil, and then cover it with soil.

3. Large -scale application: block fertilization, put the sustained -release Fertilizer into pieces into a Flower pot.

4. Light burial: Buried on the surface of the soil, although the fertilization method is more troublesome, it is a better fertilization method that can make the fertilization efficiency more uniform without losing the fertilization efficiency.

Is the slow release of Fertilizer on the surface?

Generally speaking, most people now sprinkle the sustained -release Fertilizer on the surface of the matrix when using the mild release Fertilizer. This method is more convenient and fast, which can create a gradual infiltration nutrition transmission system for plants in the Flower pot.However, there are also disadvantages of this method. When the wind is blowing the Flower pot, the Fertilizer will be split, or the Fertilizer may overflow from the Flower pot when it rains, causing losses.The editor recommends that it is best to use a shallow method to fertilize, that is, digging a few small holes without damaging the root system to bury the slow -release Fertilizer.

Will slow release Fertilizer burn the root?

Basically, there will be no roots. The release time of slow release Fertilizer is very long. The shorter may be about three months, and the long one can be up to one year.Essence

The difference between slow release Fertilizer and Compound fertilizer

Compound fertilizer refers to Fertilizer containing two or more nutrient elements, mainly contain nitrogen, phosphorus, potassium, and other medium and trace elements. The nutrient content is high and the side components are small, which can meet most of the nutrients needed for crops.

Slow -release Fertilizer is a slowly released Fertilizer. It contains only the element of nitrogen. The ingredient is single. The main role is to supplement the nitrogen element required during the growth of the plant.

The difference between slow release Fertilizer and control release Fertilizer

1. Release and Fertilizer effect

Slow -release Fertilizer is the effect of slowing nutrient release rates in the Fertilizer through chemical and biological factors. During release, it is affected by many external factors such as soil pH, microbial activity, water content in soil, soil type, and irrigation water volume.

Controlled Fertilizer is to wrap the water -soluble Fertilizer in the form of an outer envelope to slowly release the nutrients in the membrane. When the Fertilizer particles of the envelope are exposed to the humid soil, the water in the soil penetrates into the interior through the envelope, so that some Fertilizers can dissolve some Fertilizers.Essence

2. Nutritional ingredients

Most of the mild release hypertrophy is single Fertilizer. The main varieties are slow -effective nitrogen Fertilizers, also called long -acting nitrogen fertilizer, which is small in solubility in water.After the soil is applied, under the influence of chemical and biological factors, Fertilizer is gradually decomposed, and nitrogen is slowly released to meet the requirements of nitrogen during the entire growth period of the crop.

Most of the n-P-K-K Compound fertilizer or the full nutrients with trace elements are mostly controlled. After the soil is applied, its release speed is only affected by the soil temperature.

3. The release speed of nutrients

Slow -release Fertilizer releases uneven nutrients, and the speed of nutrient release is not necessarily completely synchronized with the nutritional needs of crops.

The speed of controlling Fertilizers to release nutrients is more consistent with the speed of the plant's nutrients, which can meet the nutrients of plants in different growth stages of nutrients.

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.

1. What are the inorganic Fertilizers

Inorganic Fertilizer is also known as "Chemical Fertilizer".Fertilizers composed of inorganic matter.It mainly includes single -quality Fertilizers and composite Fertilizers such as nitrogen fertilizer, phosphorus Fertilizer, Potassium fertilizer, and trace element Fertilizers.

1. nitrogen fertilizer

Inorganic Fertilizer contains nitrogen fertilizer, of which nitrogen Fertilizers contain ammonia, ammonium bicarbonate, ammonium chloride, ammonium sulfate and other Fertilizers. Ammonia water has a strong smell and has strong corrosiveness in the soil.The production of vegetables is increased, and ammonium chloride can inhibit the nitrification of rice fields and can make rice form fiber.

2. Phosphorus Fertilizer

Inorganic Fertilizer mainly includes phosphorus Fertilizer. Among them, the more common ones are calcium phosphate, phosphate powder, calcium and magnesium phosphate Fertilizer, etc. The phosphorus Fertilizer developed after using sulfate to decompose phosphate mines.There are two types of colors: gray and brown, which is suitable for use in acidic soil as base Fertilizers.

3. Potassium fertilizer

Inorganic Fertilizer mainly includes potassium Fertilizers, mainly including potassium chloride, potassium sulfate, plant ash, potassium diarrhea salt, and perple phosphate (potassium dihydrogen phosphate).Most of them can be dissolved in water, and the Fertilizer effect is fast.It can be absorbed by the soil and is not easy to lose.When applying an appropriate amount of potassium Fertilizers, the stems of the crop can grow strong, prevent falling, promote blooming and strong, and enhance the ability of drought resistance, cold, and disease -resistant pests.

4. Compound fertilizer

Inorganic Fertilizer contains compound Fertilizers, which are common potassium dihydrogen phosphate, ammonium phosphate, ammonium ammonium, potassium nitrate, etc. Potassium dihydrogen phosphate is often used as high -efficiency nitrogen phosphate Compound fertilizer.The shape is granules or powder, which is suitable for soil with a pH of 7.5.

5. Trace element Fertilizer

Inorganic Fertilizers include trace element Fertilizers, and more common ones are copper Fertilizer, boron Fertilizer, molybdenum Fertilizer, zinc Fertilizer, manganese Fertilizer, etc. The trace element Fertilizer plays an important role in the growth and development of plants.At the same time, the growth of crops is accelerated.

2. The difference between Organic fertilizer and inorganic Fertilizers

1. Different sources

Organic fertilizerThe raw materials are rotten animal and plant corpses, animal feces, and animal hair, etc.Including human dung, Fertilizer, compost, green Fertilizer, cake Fertilizer, biogas Fertilizer, etc.People also call it "green Fertilizer" or "farmhouse Fertilizer". Its source is relatively wide, which is relatively easy to collect.

Increasing Fertilizer refers to Fertilizers produced by chemical synthesis, including nitrogen, phosphorus, potassium, and Compound fertilizer.

2. Different effects

The ingredients of Organic fertilizer are relatively complicated, and it is not easy to master its dosage. It often leads to excess nutrition in some places, and there are some places to remove Fertilizer.After the use of organic Fertilizers, its decomposition speed is relatively slow, so it is relatively late, but the fertility is eased and lasting.The amount of Organic fertilizer is large and the operation is tedious, which is why many farmers' friends are unwilling to use it.

Inorganic Fertilizer, its visibility is relatively fast, the ingredients are pure, easy to grasp the amount, it saves effort and time, and it is very convenient for transportation and storage. However, its cost is not comprehensive.Excessive dosage will pollute water resources.

3. The impact on the land is different

The nutritional elements contained in organic Fertilizers are mostly organic. It is difficult to use crops directly. It must slowly release a variety of nutrient elements through microorganisms in order to supply nutrients.

When using inorganic Fertilizer, be sure not to do too much, because too much use of inorganic Fertilizer will imbalance the nutritional components of the soil, make the phenomenon of the land of the land more serious, and the minerals containing will also be accelerated, so that the soil will be even moreBarren, resulting in low productivity of the land.It is best to cooperate with each other, mainly Organic fertilizer, and inorganic Fertilizer as aid. This can not only improve the growth rate of crops and improve the growth environment.

[Calcium, magnesium phosphorus Fertilizer] The role and purpose of calcium magnesium phosphorus Fertilizer chemical calcium, magnesium phosphate Fertilizer

Calcium and magnesium phosphate Fertilizer is a raw material prepared by phosphate and magnesium silicate minerals. It is melted at 1350 ~ 1500 c in electric furnaces, blast furnaces or flat furnaces.After becoming a product.Calcium and magnesium phosphorus Fertilizer, also known as melting magnesium phosphate Fertilizer Fused Calcium-Magnesium Phosphat (Fertilizer), is a silicon aluminate vitreous containing PO4 3-).The main ingredients include CA3 (PO4) 2. Casio3, MGSIO3.It is a variety of Fertilizers. The aqueous solution is alkaline. It can improve the acidic soil. When cultivating large seedlings, it can be used as a base Fertilizer. The plant can slowly absorb the required nutrients.

Calcium, magnesium phosphorus Fertilizer chemical formula

Calcium magnesium phosphate Fertilizer is a mixture, a variety of Fertilizers. The aqueous solution is alkaline and can improve the acidic soil.GB20412-2006 Calcium Magnesium Phosphorus Fertilizer

The role and purpose of calcium magnesium phosphorus Fertilizer

Calcium and magnesium phosphorus Fertilizer is gray-green or gray-brown powder, with a phosphorus content of 12%to 18%. The main component is that it can dissolve citric acid -CA3 (PO4) 2, and also contain elements such as magnesium and small silicon.Magnesium is beneficial to the formation of chlorophyll (the important component of chlorophyll molecules is C55H72O5N4MG and C55H70O6N4mg), and silicon can promote the growth of crop fiber tissue, so that plants have better ability to prevent inverted and pests.When cultivating large seedlings, it is effective as a base Fertilizer, and plants can slowly absorb the required nutrients.

How to apply calcium, magnesium phosphorus Fertilizer

(1) Most suitable for base Fertilizer.After calcium and magnesium phosphorus Fertilizer is applied to the soil, the phosphorus can only be dissolved by weak acids. It must be used through a certain transformation process to be used by crops.Generally, we must combine deep cultivation, and the Fertilizer is evenly applied to the soil to mix it with the soil layer to facilitate soil acid dissolving and the absorption of crops.

(2) High -quality Organic fertilizer mixed with high -quality Organic fertilizer with more than 10 times or more. The prepared Fertilizer can be used as base Fertilizer, planting Fertilizer, or dipped in seedlings.

What are the effects of trace element Fertilizers

When a trace element is lacking, the growth and development of crops are significantly affected, the output decreases, and the quality decreases.On the other hand, excessive trace elements can poison crops, which affects production and quality lightly, and even endangers health.

What are the trace element Fertilizers

Those trace nutritional elements that are indispensable for normal growth and development of plants are agricultural as chemical products for Fertilizer. Like boron Fertilizer, zinc Fertilizer, manganese Fertilizer, molybdenum Fertilizer, copper Fertilizer, iron Fertilizer, cobalt Fertilizer, they are micro Fertilizers.These trace elements account for roughly: 0.05%manganese, 0.02%iron, zinc 0.01%, boron 0.005%, copper 0.001%, molybdenum 0.0001%.

1. Divided by nutrients:

(1) Single quality slightly fat.This type of Fertilizer generally contains only one trace element required for crops, such as zinc sulfate and iron sulfate.Most of these Fertilizers are easily soluble in water.Therefore, it is convenient to apply, can be used as base Fertilizer, Fertilizer, and topdressing.

(2) Compound micro -Fertilizer.Most of this type of Fertilizer is made of one or more trace elements when making Fertilizers. It includes a large amount of elements and trace elements and the composite between trace elements and trace elements.For example, ammonium phosphate zinc, ammonium phosphate manganese, etc.This type of Fertilizer, one time is applied to several kinds of nutrients at the same time, which is more labor -saved, but it is difficult to achieve local conditions.

(3) Mixed micro -Fertilizer.This type of Fertilizer is made of various single -quality Fertilizers when manufacturing or applied.

2. According to the type of micro -Fertilizer compounds:

(1) Easy -soluble inorganic salt.Most of these Fertilizers are sulfate.

(2) Unsaccharide inorganic salt.Most of them are phosphate and carbonate, and some are oxides and sulfur.For example, ammonium phosphate zinc, zinc chloride, etc.Suitable for base Fertilizer.

(3) glass Fertilizer.Most of the silicate powder containing trace elements, sintering or dissolving through high temperature

For glass -like substances, such as the stabs of the smelter, can generally only make bottom Fertilizer.

(4) Cheese Fertilizer.It is a compound of natural or artificial synthesis, chelated with trace elements, such as chelating zinc.

(5) Industrial waste with trace elements.

How to use trace element Fertilizers

1. Soil fertilization

In addition to chemical Fertilizers (such as borax, zinc sulfate, manganese sulfate, etc.), commonly used, as well as integrating Fertilizer, glass Fertilizer, slag, or lower foot material, they are usually used as base Fertilizers and planting Fertilizers.The application method is to be applied to the soil before sowing, or mixed with nitrogen, phosphorus, potassium and other chemical Fertilizers.For rice, zinc sulfate is applied for 1 kg per acre, and borax generally uses 0.5 kg to 1 kg per mu. It must be mixed with Organic fertilizer such as Fertilizer Fertilizer to prevent concentrated application of local hazards.

2. Follow the roots

The soluble micro -Fertilizer is distributed into a certain concentration of water solution, and the stems and leaves of the crop are sprayed.The advantage of this method is to avoid the harm caused by uneven Fertilizer in the soil. At the same time, it can also be sprayed multiple times according to specific needs in the different stages of the crops to improve Fertilizer effects.Conditional areas can use mechanical operations or aircraft spraying when applying large areas, and generally spray concentrations from 0.01%to 0.05%.

3. seed treatment

Wain the seeds or seedlings with trace elements before sowing. This is the most economical and effective method, which can greatly save Fertilizer.The concentration of soaking species of boric acid or borax is 0.01%to 0.03%.Only a solution of 5 liters per 500 kg of seeds.Soybean is mixed with ammonium molybdenonate and only 10 grams to 20 grams per acre.
