Anonymous users2024-02-15Nitrogen fertilizer refers to a unit fertilizer that uses nitrogen as the main component and is applied to the soil to provide plant nitrogen nutrients.
Nitrogen fertilizer is the most produced and used fertilizer variety in the world; Appropriate nitrogen fertilizer dosage plays an important role in increasing crop yield and improving the quality of agricultural products.
There are three commonly used nitrogen fertilizers: ammonium nitrogen, nitrate nitrogen and amide nitrogen, each of which has the following effects:
1. Ammonium nitrogen, ammonium nitrogen has a large solubility, so it can be quickly absorbed and utilized by plants, so it is used more in chemical fertilizers, but it should be noted that the soil acidity and alkalinity should be paid attention to when applying, if it is alkaline soil, ammonium-containing nitrogen fertilizer can not be used, because ammonium nitrogen exists in the form of ammonium ions, which is acidic, and if applied in alkaline soil, acid-alkaline neutralization will occur, resulting in the loss of fertilizer effect.
2. Nitrate nitrogen, nitrate nitrogen fertilizer is mainly used in alkaline fertilizer, soluble in water and absorbed by plants, because it itself belongs to physiological alkaline fertilizer, but there is a disadvantage that it is easy to wet and agglomerate, so we should pay attention to moisture-proof and rain-proof in preservation.
3. Amide nitrogen, the most common amide nitrogen fertilizer in fertilizers is urea.

Nitrogen is the main component of proteins. 3. Promote growth: Nitrogen fertilizer can increase the content of chlorophyll in plants, accelerate their nutrient absorption, and thus promote growth.
1. Promote photosynthesis
Nitrogen fertilizer contains more nitrogen, which is an important component of chlorophyll and biological enzymes, and the application of nitrogen fertilizer can increase the content of chlorophyll and biological enzymes in plants, so as to promote its photosynthesis and synthesize the nutrients required for plant growth.
2. Promote protein synthesis
Sufficient nitrogen can form protein, and protein is the material basis of life activities, in the process of cultivating plants, providing them with nitrogen-rich fertilizers can maintain the growth of plants and promote their vigorous growth.
3. Promote growth
Nitrogen fertilizer has the effect of promoting growth, the use of nitrogen fertilizer when planting trees, can increase the content of chlorophyll, promote the growth of new leaves, and the use of nitrogen fertilizer as foliar fertilizer or liquid fertilizer, can allow roots and leaves to absorb sufficient nitrogen, grow more vigorous and lush.

Anonymous users2024-02-12The main role of nitrogen fertilizer is to promote the growth of plant stems and leaves, improve the nutritional value of agricultural products and increase yield.
There are many types of nitrogen fertilizers, among which urea is the fertilizer with the highest ammonia content among solid ammonia. When using urea, you should not use too much at one time, which will cause fertilizer damage and cause plant growth. For the use of ammonia fertilizer, it is recommended to test the 10 soils in advance.
Nitrogen fertilizer is generally divided into two types, inorganic nitrogen fertilizer, organic nitrogen fertilizer, organic nitrogen fertilizer, plant nitrogen fertilizer, animal nitrogen fertilizer, and plant nitrogen fertilizer.
We usually have the most common oil cake, bean dregs, etc., animal nitrogen fertilizer is the manure of livestock, etc., all belong to this animal nitrogen fertilizer, inorganic nitrogen fertilizer includes, is a chemical fertilizer, is what we often call chemical fertilizer, such as nitroamine, ammonia and so on.
Introduction to nitrogen fertilizer hubback
Nitrogen fertilizer refers to a unit fertilizer with nitrogen n as the main component, with n marked amount, and can provide plant nitrogen and nutrient when applied to the soil. Nitrogen fertilizer is the most produced and used fertilizer variety in the world; Appropriate nitrogen fertilizer dosage plays an important role in increasing crop yield and improving the quality of agricultural products.
Nitrogen fertilizer can be divided into ammonia nitrogen fertilizer, ammonium nitrogen fertilizer, nitrate nitrogen fertilizer, ammonium nitrate nitrogen fertilizer, cyanide nitrogen fertilizer and amide nitrogen fertilizer according to the nitrogen-containing group.
In the forties and fifties of the 20th century, ammonium sulfate was the most important nitrogen fertilizer variety, and in the sixties, ammonium nitrate was added. Since the 70s, urea has become the dominant nitrogen fertilizer variety.

Nitrogen fertilizer allows trees to flourish and thrive. 3. Synthesis of protein: Nitrogen is the main component of protein in crops, which needs to be supplemented with nitrogen fertilizer.
4. Increase yield: Nitrogen fertilizer as base fertilizer can increase the yield of crops.
1. Function
The main function of nitrogen fertilizer is to promote the growth of plant stems and leaves, make the leaves of plants more green, improve the protein content of seeds, improve the nutritional value of agricultural products, and nitrogen fertilizer also has an obvious yield increase effect, which is better than phosphorus and potassium fertilizer.
2. Types of nitrogen fertilizers
There are many types of nitrogen fertilizers, mainly ammonium nitrogen fertilizers, nitrate nitrogen fertilizers, ammonium nitrate nitrogen fertilizers, and amide nitrogen fertilizers. Amide nitrogen fertilizer is also known as urea, which is the fertilizer with the highest nitrogen content among solid nitrogen.
3. Precautions
In the process of using nitrogen fertilizer, we should first pay attention not to use too much at one time, the effect of nitrogen fertilizer is very prominent, but the damage to the plant is also the greatest due to excessive one-time use, it is easy to burn the roots of the plant, and it is easy to lead to the occurrence of plant growth.
4. Tips for using nitrogen fertilizer
The amount of nitrogen fertilizer is related to the amount of nitrogen supply of the soil, the ability to retain fertilizer and the nitrogen absorption of crops.
The nutrients needed for plant growth can be prepared with the corresponding inorganic salts, rather than relying only on the soil; This is a fact that has long been scientifically confirmed, and it is also an important theoretical basis for modern agriculture, soilless cultivation and tissue culture. However, when preparing such chemical fertilizers, it is necessary to prepare and apply according to the acceptance of fertilizer concentration of specific plants (% bamboo bamboo can be lower, pineapple is the lowest) and physiological state (foliage plants or leaf germination stage, the proportion of nitrogen required is high, and the proportion of phosphorus and potassium at the flower and fruit stage is high).
Urea and nitrogen fertilizer as a common fertilizer for fertilizing fruits and vegetables in rural areas, both are different in the definition of appearance and applicability, from the effect of fertilization, the effect of nitrogen fertilizer is better, nitrogen as a necessary element in plant growth, can promote the transformation of nutrients in fruits and vegetables. >>>More
Reasons why plant ash and ammonium nitrogen fertilizer cannot be mixed:After the mixing of plant ash and ammonium nitrogen fertilizer, the double hydrolysis reaction will occur, and the ammonia gas will easily escape, resulting in the equilibrium shifting to the right, and the concentration of ammonium ions in the soil will decrease, and then the fertilizer efficiency will decrease. >>>More
1. Raise military spending.
In times of war, military expenditures were enormous, and in the absence of other means of financing, they were raised through the issuance of war bonds. The issuance of war treasury bonds is a common method used by all countries in wartime, and it is also the first origin of treasury bonds. >>>More
