Can borax and urea be mixed as foliar fertilizer?

Borax is mainly applied during the flowering period of fruit trees or crops and can improve fruit set. Apply a concentration of 300 500 times the liquid and spray it evenly.

1. Boron fertilizer should not be mixed with compound fertilizer. 2. Boron fertilizer is mainly foliar spraying, and compound fertilizer is mainly ground fertilization. 3. Boron fertilizer is mixed with compound fertilizer, which has a large cost, no fertilizer effect, and no calculation.

4. Crops need an appropriate amount of boron and excessive, the scope of poisoning is very narrow, and boron fertilizer has an after-effect, the dosage should be strictly controlled, evenly applied, and the fertilizer effect can last for 3-5 years to prevent excessive application of poison. 5. The fertilization method is mainly foliar spraying. The borax or boric acid solution used is sprayed about 50 kg per mu and sprayed 2-3 times.

Among them, rape was sprayed in the late seedling stage, the budding stage, and the early flowering stage. Fruit trees are sprayed at the budding stage, flowering stage, and young fruit stage. Boron fertilizer has the effect on crop flowering and fruiting, accelerating carbohydrate transport in the body, enhancing photosynthesis, and forming nodules of leguminous crops, which can improve the drought and cold resistance of crops, and is conducive to preventing physiological diseases of crops.

The application of boron fertilizer has a significant effect on the prevention and control of the symptoms of "buds but not flowers" of cotton, "flowers but not fruits" of rapeseed, and "falling flowers and fruits" of fruit trees. Boron-sensitive crops are mainly leguminous and cruciferous crops (e.g., rapeseed, peanuts, soybeans, etc.), followed by fruit trees, vegetables and cotton. Cereal crops such as rice, wheat, and corn are less sensitive to boron.

Borax varieties include borax and boric acid, and borax is commonly used.

Boron fertilizer is best used as a base fertilizer and cannot be used during flowering; Zinc fertilizer can be sprayed as a base fertilizer top dressing, but it needs to be used every other year because it has a long residue in the soil; These two can be mixed with urea alone, but the ratio of use should be accurately mastered, and it can be tested in advance to avoid fertilizer damage.

Boron fertilizer can be mixed with urea and compound fertilizer. Boron fertilizer and urea can be used together, boron fertilizer and urea do not have a chemical reaction, they can be used together, and the fertilizer effect is the same. Rational application of boron fertilizer.

Basal application: Borax can be used as basal fertilizer for heavy boron deficient soils to prolong the time of soil boron supply. Boron fertilizer is mixed with human and animal manure or chemical fertilizer liquid in watering, and the effect is more significant than that of dry application when watering holes as base fertilizer or top dressing at seedling stage when sowing.

Extended information: 1. What is the effect of boron fertilizer on crop growth and development?

Boron can promote root growth and photosynthesis.

of the product - carbohydrates.

The synthesis and transport play an important role, and have a special role in the normal progress of the fertilization process. Therefore, the control of rape"Flowers but not fruits", cotton"Buds but not flowers"and fruit trees"Falling buds, falling flowers, falling fruits", wheat"No, no"and other symptoms. If leguminous crops are deficient in boron, the nodules are underdeveloped and even lose their ability to fix nitrogen.

2. Are chemical fertilizers harmful to the human body?

Fertilizers are harmful to humans. The nitric acid in chemical fertilizers is reduced to nitrite by human bacteria, and nitrite is a carcinogen that can cause cancer. There are too few "green foods" in the three meals of Chinese, and chemical fertilizers have become the biggest potential killer in our food structure, and it is difficult for us to get rid of it, and long-term accumulation in the body will form toxins.

3. What raw material is urea produced?

The raw materials for the production of urea are mainly liquid ammonia and carbon dioxide.

Gas, liquid ammonia is the main product of the ammonia plant, and carbon dioxide gas is a by-product of the purification of the ammonia feedstock. Liquid ammonia used in the synthesis of urea requires higher purity, oil content less than 10ppm, water and inert gas.

It is less than and does not contain solid impurities such as catalyst powder and rust. The purity of carbon dioxide is required to be greater than 15mg nm3 of sulfide.

4. Is urea an organic substance?

It's organic. Urea is an organic compound composed of carbon, nitrogen, oxygen, and hydrogen. Organic compounds in the narrow sense mainly refer to the element carbon.

Hydrogen elemental composition, which must be carbon-containing compounds, but does not include carbon oxides and sulfides, carbonic acid, carbonates, and cyanides.

Thiocyanide, cyanate, carbide, carborane, carbonyl**, m-c-bond-free metal-organic ligand complexes.

5. Is urea nitrogen fertilizer?

Yes, urea is a nitrogen fertilizer, urea, also known as carbonamide, is an organic compound composed of carbon, nitrogen, oxygen, and hydrogen is a white crystal. One of the simplest organic compounds is mammals.

and the main nitrogen-containing end product of protein metabolism in some fish. It is also the nitrogen fertilizer with the highest nitrogen content at present. As a neutral fertilizer, urea is suitable for a wide range of soils and plants.

It is easy to preserve, easy to use, and has little damage to the soil, and is a chemical nitrogen fertilizer that is currently used in large quantities.

Boron fertilizer can not be mixed with urea, compound fertilizer and other fertilizers, easy to chemical reaction, boron fertilizer and urea are easy to deliquescent after mixing, and boron fertilizer and compound fertilizer mix not only increase the cost, but also have no fertilizer effect, boron fertilizer is mainly sprayed foliage, and compound fertilizer is fertilized on the ground, together with the use of will affect the growth of crops.

1. Boron fertilizer cannot be mixed with anything.

1. Boron fertilizer generally cannot be used with compound fertilizer, urea and other fertilizers to avoid chemical reactions. If it must be mixed with compound fertilizer, urea, etc., it is necessary to consider whether it will cause the lack of crop nutrients after mixing, whether it can help improve fertilizer efficiency after mixing, and whether it will improve the physical properties of the soil after mixing.

2. Boron fertilizer is mainly sprayed on the foliage, while compound fertilizer is ground fertilization, and the mixture of the two increases the cost and reduces the fertilizer efficiency.

3. Boron fertilizer is a trace element required for plant growth, and the appropriate application of boron fertilizer (Trim boron fertilizer) can enhance the drought resistance and disease resistance of crops, and can appropriately promote the early maturity of crops.

Boron fertilizer can be mixed with urinary disorders, and these two fertilizers do not contradict each other, and mixed use will not cause harm.

This can be mixed with urea and poured.

Summary. 1. Agricultural borax generally cannot be mixed with compound fertilizer, because boron fertilizer is mainly foliar spraying, while compound fertilizer is mainly ground fertilization.

2. In addition to being unable to mix borax (boron fertilizer) with compound fertilizer, it should not be mixed with urea and other fertilizers. If boron fertilizer needs to be mixed, it is necessary to consider whether the fertilizer efficiency can be improved after mixing, whether the physical properties of the soil can be improved after mixing, and whether it will cause the lack of crop nutrients after mixing.

3. Boron fertilizer is weakly acidic, usually can not be mixed with calcium fertilizer, alkaline fertilizer, easy to antagonistic reaction, but generally can be mixed with potassium dihydrogen phosphate spraying or flushing. Note: Do not apply too high boron fertilizer to avoid poisoning.

Can compound fertilizer be combined with borax?

1. Agricultural borax can not be mixed with compound fertilizer as a wear-resistant, because boron fertilizer Changzhen bucket is mainly foliar spraying, and compound fertilizer is mainly ground fertilization, if it is mixed, it may not be able to play the original fertilizer effect, so it is not recommended to mix. Travel.

2. In addition to being unable to mix borax (boron fertilizer) with compound fertilizer, it should not be mixed with fertilizers such as urin. If boron fertilizer needs to be mixed, it is necessary to consider whether the fertilizer efficiency can be improved after mixing, whether the physical properties of the soil can be improved after mixing, and whether it will cause the lack of crop nutrients after mixing.

3. Boron fertilizer has weak acidity or nature, usually can not be mixed with calcium fertilizer, alkaline fertilizer, easy to antagonistic reaction, but generally can be mixed with dihydrogen potassium phosphate spraying or flushing. Note: Do not apply too high boron fertilizer to avoid poisoning.

Abstract Dear, hello, glad to answer for you, phosphate fertilizer and urea can be mixed. Urea is a fast-acting nitrogen fertilizer with high nitrogen content, while phosphate fertilizer is a fertilizer-based phosphorus, which can meet the nitrogen and phosphorus needs of crops after mixing, and in addition, potassium fertilizer can also be added to apply together.

Can a mixture of phosphate fertilizer and urea be used as a base fertilizer for wheat?

Hello dear, I am glad to answer for you, phosphate fertilizer and urea can be mixed. Urea is a fast-acting nitrogen fertilizer with high nitrogen content, while phosphate fertilizer is a fertilizer-based phosphorus, which can meet the nitrogen and phosphorus needs of crops after mixing, and in addition, potassium fertilizer can also be added to apply together.

However, if you plant wheat as a base fertilizer, you don't need to add urea, just use compound fertilizer, wheat likes phosphorus fertilizer, you should use a higher phosphorus content to have a better effect, or use 15-15-15 general fertilizer, but don't use high nitrogen, high potassium and low phosphorus, that kind of fertilizer is suitable for fruit trees and vegetables. Generally, 70-100 kg of compound fertilizer per mu is used for wheat base fertilizer, and 50-60 kg of urea can be applied in spring. The soil fertility is different in different places, and the dosage varies slightly.

Boron fertilizer can not be mixed with urea, trace slow song compound fertilizer and other fertilizers, easy to chemical reaction, boron fertilizer and urea are easy to deliquescent after mixing, and boron fertilizer which bench and compound fertilizer mix not only increase the cost, but also has no fertilizer effect, boron fertilizer is mainly sprayed foliage, and compound fertilizer is fertilized on the ground, together with the application will affect the growth of crops.
