[Chemical Fertilizer] What are the main components of chemical Fertilizers in Chemical Fertilizer?

What are the main components of chemical Fertilizers

1 , nitrogen fertilizer: Chemical Fertilizer with nitrogen nutrition elements as the main ingredient, including ammonium bicarbonate, Urea, ammonium sales, ammonia, ammonium chloride, ammonium sulfate, etc. Essence

2 , Phosphate Fertilizer: Chemical Fertilizer with phosphate nutrition elements as the main ingredient, including ordinary excess calcium phosphate, calcium magnesium phosphate Fertilizer, etc. Essence

3 , Potassium fertilizer: Chemical Fertilizer with potassium nutrition elements as the main ingredient. At present, there are not many. The main varieties are potassium chloride, potassium sulfate, potassium nitrate, etc.

4 , Repeated and mixed Fertilizer: That is, Fertilizer contains two Fertilizer three elements (nitrogen, phosphorus, potassium) binary compound, mixed Fertilizer, and trigly compound, mixed Fertilizer containing nitrogen, phosphorus, and potassium. Among them, mixed Fertilizer promoted quickly throughout the country.

5 , Trace element Fertilizer and certain medium -sized element Fertilizers: The former is Fertilizer with trace elements such as boron, zinc, iron, molybdenum, manganese, copper, and the latter such as calcium, magnesium, sulfur and other Fertilizers.

6 Followed by some crops: such as steel slag silicon Fertilizer applied on rice, cobalt Fertilizer applied to the bean crops, as well as agricultural rare earths used on sugarcane and fruits.

What are the harmful components in chemical Fertilizers?

1 Damage to crops

Fertilizers are composed of various salt, so these Fertilizers composed of salt categories have been applied for a long time. When Fertilizers enter the soil, they will increase the concentration of soil solutionDo not absorb water from the soil solution, but the water in the cytoplasm is inflated into the soil solution, causing crops to be harmed.Typical examples are crops"Burning seedlings"

After a large amount of pesticides is applied, pesticide residues or deep groundwater are caused, which also causes pollution to water.In recent years, the low price of garlic is because pesticide residues have exceeded standards. Foreign acquirers have canceled acquisitions and caused.We may also be unqualified by what we eat, but the awareness of the domestic people is not so high, and the cost of the test is too high.Ordinary people cannot afford it.

2 Pollution to the environment

Rich nutrition of rivers, lakes, and inland sea.The cause of richer nutritional in the waters is mainly to increase the content of nitrogen and phosphorus in water, so that the algae and other aquatic plants grow too much.

The soil is polluted and the physical properties of the soil deteriorate.Long -term excessive and simply applying chemical Fertilizers can acidify the soil.The ammonia ion of organic and inorganic complexes in the soil solution increased and the ammonia ion increased by organic and inorganic complexes. CA2 As well as MG2 Wait, scattered soil collagen, damage to the soil structure, the landing of the land, and directly affect the cost and quality of agricultural production and crops.

Increased toxic ingredients in food, feed and drinking water.Nitrite biological toxicity is larger than nitrite 5 ~ 10 Double, a combination of nitrite and amine N -Nitukin compound is a strong carcinogen (see N -Nitogen compounds and cancer).The content of nitride in the well or river water in areas with chemical Fertilizers will increase, or even exceed the standard of drinking water.Too much soil with chemical Fertilizers will increase the nitrate content in crops such as vegetables and pastures.The nitrite content in food and feed is too high, which has caused children and livestock poisoning accidents.Chemical Fertilizer also contains other impurities, such as cadmium in phosphorus ore 10 ~ 100ppm , Lead 5 ~ 10ppm These impurities can also cause environmental pollution.

Increased nitrogen oxide content in the atmosphere.The nitrogen fertilizer applied to farmland has a considerable amount of volatilization from the surface of the soil into a gas and entering the atmosphere.A considerable part of the form of organic or inorganic nitrogen enters the soil. Under the action of soil microorganisms, it will be converted into nitrogen and nitrogen oxides from the pumpkin, adsorption state, and water -soluble.To prevent environmental pollution, control and manage chemical Fertilizers used.

rice vinegar

When fertilizing the flowers, pay attention to the proper drop of rice vinegar in the appropriate liquid Fertilizer, which can eliminate the odor of liquid Fertilizer, because rice vinegar is weak acidic, which can neutralize the smell produced by some corrupt substances in liquid Fertilizers.

Orange peel

In the fermented Fertilizer, you can put some orange peel((Fresh or air -drying can be availableCure, Make orange Skin and Fertilizer.The use of a large amount of aromatherapy oil contained in orange Skin can reduce the smell of liquid Fertilizer, and the orange Skin is also a good Fertilizer after fermentation.

Liquor

Flower farmers often say"The taste of the potted water is strong, and the smell of liquor is extinguished."It makes sense.Adding some liquor in Fertilizer during fertilization can clearly remove the odor.In addition, flower friends can also make some Fertilizers without odor at home.

Use broken Bone Fertilizer

Many people who raise flowers at home use the shattered bones of chickens and ducks as flower Fertilizers.The specific method is to remove the bones for a day or two to remove the salt.

Then use the high -pressure cooker to add water and stuffy, stir it into a paste, and then add 20 % of the fine sand or ceda ash in it. After mixing it, a layer of dry soil is covered on the costumes and sprinkled some pesticides.

Then stamped and keep it loose and humid. After two or three months, the Fertilizer was fully rotten, and the Flower pots were effective and there was no odor.

Use yogurt, eggshell Fertilizer

Rinse the yogurt bottle with rice water((boxCureWashing water and shattered eggshells, then put it together7Day10God can become a kind of nutrients and Fertilizers, with high -ending of flower Fertilizer and no odor.

flowers who do not have time to make Fertilizers, when using ordinary liquid Fertilizers, can take the following methods to reduce the odor:

Qiaoli

Before fertilizing, reduce the amount of watering, dry the pot soil, and then irrigate the Fertilizer outdoors in the evening.Because the soil is dry, it will speed up the speed of the absorption of Fertilizer and reduce the exposure of Fertilizer.

Therefore, after the Fertilizer is penetrated into the pot soil, a small amount of water can be poured and the surface residual Fertilizer can be washed to the lower soil. This can eliminate the odor of the Fertilizer.It can also greatly reduce the odor.

Cover the soil after application

Place some Fertilizers with a strong smell in the container and sealed. After fermentation and rotten, dilute it with water10Use about it.After applying, cover the surface of the pot on the surface of the pot, which prevents the odor from volatile, but also maintains Fertilizer.

What does it mean to control the Fertilizer?

Controlling Fertilizer is a high -form form of slow -release Fertilizer. It mainly controls the release of nutrients through envelope technology to achieve the purpose of safe, long -term and efficient. It is the main direction of modern Fertilizer development. It is suitable for mechanized production. The broadcast needs to wait.

What are the characteristics of controlling Fertilizer

The first is to increase the utilization rate of chemical Fertilizers and reduce the amount of Fertilizer.

Because controlling and release of Fertilizer has a slow -release effect, it can reduce the gaseous and leaching loss of chemical Fertilizers, thereby improving the efficiency of the utilization of chemical Fertilizers.The test data shows that the controlling Fertilizer can increase the utilization rate of Fertilizers from about 35%, and the loss rate of nitrogen fertilizer is significantly reduced, which can save 30%-50%of nitrogen fertilizer.

The second is to reduce the number of Fertilizers and save labor.

Due to the lack of labor in rural areas or due to lack of water and inadequate water supply, crop fertilization is becoming increasingly simplified, and one -time fertilization of crops is quite common.At present, the one -time Fertilizer sold on the market is basically fast -acting high -nitrogen -type Compound fertilizer, and there is a risk of long -term seedling or later Fertilizer.The release of the release of Fertilizer can be scheduled to design the release mode of the Fertilizer in the growth season of the crop, so that the law of the nutrient release of the Fertilizer is consistent with the absorption of crop nutrition, and one -time fertilization meets the needs of the entire growth season of crops.

Controlling Fertilizer can also be used for cultivation of farming and soil -free cultivation. seeds and Fertilizers can be sowed, and irrigation is sufficient, which is very convenient.Many soil -free cultivation of irrigation nutrient solution.Sometimes the nutrient solution is not well matched, and the Miao Changshi is not good. It solves this problem with controlling Fertilizer.

The third is to reduce crop disease and improve the quality of agricultural products.

Crop disease and product quality are related to the amount of nitrogen fertilizer. Applying controlling and release Fertilizer can prevent crops from absorbing excessive absorption of nitrogen, thereby suppressing diseases and improving quality.

How to use release Fertilizer

When using, Fertilizer isolates and covers soil after application. For example, when planting corn and cotton crops, the distance between the seeds and Fertilizers is about 7-10 cm, the depth of fertilization and sowing is about 10 cm.

Note:

1. When the use of controlling Fertilizer is used, the amount can generally be applied according to 80%of the Fertilizer in previous years. At the same time, it is necessary to increase or decrease appropriately according to different crops, target yield, and soil conditions.

2. Not suitable for the use of drought land and sandy land.In the absence of moisture, nutrients cannot be effectively released, which may cause crops to affect the growth due to the inability to absorb effective nutrients and cause crop production to reduce production.

The difference between control release Fertilizer and slow release Fertilizer

Control and release Fertilizer: It mainly controls the release of nutrients by performing envelope on the Fertilizer. The Fertilizer has a longer Fertilizer and more nutrients, but it is only suitable for use in the peak of the crop. , Roots and mountain spray irrigation.

Smooth -release Fertilizer: The Fertilizer effect is relatively slow, and its composition is relatively single. The main elements contained in are nitrogen elements, and the water solution itself is relatively low.

The difference between controlling and Compound fertilizer

Control and release Fertilizer: It mainly controls the release of nutrients through envelope technology. The Fertilizer effect is longer, and the nutrients containing are relatively comprehensive, but it is only suitable for crops to use it at the peak of the need for Fertilizer. Roots, mountain spray irrigation, etc.

Compound fertilizer: It mainly contains nitrogen, phosphorus, potassium and other elements. It is generally appropriate to fertilize (gap, acupuncture, etc.) when fertilizing, and it is usually used as base Fertilizer.
