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.
Urea and nitrogen fertilizer are common fertilization fertilizers in rural areas, but there are still certain differences between the two, first of all, in the definition, nitrogen fertilizer refers to the stone as the main component, after fertilization can provide nitrogen for plants. Urea refers to a neutral fertilizer composed of organic compounds such as carbon, nitrogen, oxygen, hydrogen, etc. The two are also different nitrogen fertilizers in appearance, in addition to ammonia, liquid, ammonia, there are also crystalline appearances.
Urea, on the other hand, is a white crystalline in appearance. In terms of applicability, there are relatively many types of nitrogen fertilizers, including urea. Urea is relatively easy to preserve, suitable for a variety of soils and plants, and relatively less destructive to the soil.
Nitrogen is one of the important fertilizers for the growth of fruit trees, and farmers often use nitrogen fertilizer to fertilize orchards in the process of planting trees, in order to allow fruit trees to absorb enough nutrients to promote their germination and growth. Fertilization of orchards in spring must be supplemented with nitrogen fertilizer for fruit trees, especially after a winter of hibernation, in order to promote the differentiation of flower buds of fruit trees into the growth period, at this time, timely nitrogen fertilizer for them can help fruit trees promote photosynthesis, lay a solid foundation for the subsequent growth and fruiting of fruit trees, and improve the yield of fruit trees.
In fertilizing fruit trees, urea can be used, but try not to sprinkle it, on the one hand, throwing urea will lead to excessive use of urea, resulting in soil acidification and soil compaction. Curtains will have a serious impact on the soil quality, and it is also not good for the growth of fruits and vegetables. In addition, the application of urea will also cause the cost of fertilizer to rise, and a large area of urea heaped in the orchard may cause weeds and fruit trees to grab fertilizer, which is not conducive to the germination and differentiation of fruit trees.
Therefore, in the fertilization method, ditching fertilization is generally used to cover the soil to avoid the waste of urea fertility.
Farmers pay great attention to the combination of nitrogen, phosphorus and potassium fertilizers in the process of fertilizing fruit trees. In order for fruit trees to grow healthily and strongly, it is not advisable to use a large number of chemical fertilizers, but to use organic fertilizers, the demand for nitrogen fertilizer in the early stage will be greater, and phosphate fertilizer and potassium fertilizer should be added in the later stage.
All in all, urea and nitrogen fertilizer are both important fertilizers in fruit tree fertilization, and the effect of nitrogen fertilizer application is better in terms of the fertilizer demand of fruit trees and the impact on the soil around fruit trees. Urea can be used in combination, but try not to use it in a throwing way. According to the growth cycle of fruit trees, apply different fertilizers as reasonably as possible, pay attention to the proportion of nitrogen fertilizer, so as to promote the growth of fruit trees more vigorously.
-
Nitrogenous fertilizer. Because fat is important. I believe that friends who are engaged in agricultural production and planting know that in the growth process of plants, the three elements of nitrogen, phosphorus and potassium are the most important, of which nitrogen is the most important.
When spring comes after hibernation of fruit trees, fertilizer should be supplemented in time to make fruit trees obtain sufficient nutrients, promote the differentiation of fruit tree flower buds, and enter the growth period as soon as possible.
-
Ammonium carbonate and urea belong to nitrogen fertilizers, both can be used as top dressing, because both have strong water solubility and volatility, so they need to be used in soil covering, not on the surface. In addition, the two are easy to volatilize ammonia in the decomposition process, and it is easy to burn seeds when used as seed fertilizer, and if it is used on crop leaves, it is easy to burn the leaves.
-
Urea can be applied to fruit trees to help them photosynthesize, thereby increasing the nutrients of the tree, which can make the branches grow robustly, and the leaves are hypertrophied and colorful.
At the same time, it can improve the photosynthetic efficiency of leaves, increase the accumulation of organic nutrients, promote the formation of flower buds, have a high flowering and fruit setting rate, increase the yield and quality of the fruit, and it does not leave any harmful substances in the soil, and there is no adverse effect on fruit trees after long-term application.
Urea is an organic nitrogen fertilizer, which can be absorbed and utilized by crops after being hydrolyzed into ammonium carbonate or ammonium bicarbonate by urease in the soil.
For low apple trees, the nitrogen content of the root system is low during the budding period, so it should be paid attention to the topdressing of urea in the early growth stage to supplement the lack of nitrogen absorption by the root system, which is of great help to the growth of fruit trees. Foliar application of urea during the flowering period of apple trees had a good effect on improving the fruit setting rate of fruit trees. Foliar spraying of high concentrations of urea in late autumn can increase the stored nutrients and benefit the growth and development of fruit trees in the second year.
-
Urea watering fruit trees is very good and the fertilizer effect is long.
However, there are disadvantages: the cost is high, and it is easy to burn seedlings, so it should be watered more.
If it is a large area of fruit trees is possible, if there are not many fruit trees, it is recommended to directly apply human manure, the fertilizer efficiency is better than urea, and cheaper.

Let's start with urea. Urea, also known as carbaamide, is a white crystalline organic compound composed of carbon, nitrogen, oxygen, and hydrogen. 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. In addition, urea has little destructive effect on the soil, and is a chemical nitrogen fertilizer that is currently used in large quantities. Ammonia and carbon dioxide are used in industry to synthesize urea under certain conditions.
Manure. Urea is a single fast-acting nitrogen fertilizer with high content, suitable for various crops and various soils, and is the first fertilizer to supplement nitrogen fertilizer in production. The compound fertilizer is generally a fertilizer containing two or more elements, compared with a single fertilizer type, the nutrients are comprehensive, a fertilization can supplement a variety of nutrients, fertilization is convenient, high efficiency, in addition to the use of a large number of base fertilizers, the production is also carried out top dressing, especially in the middle and late growth of fruits and vegetables when the amount of fertilizer is large.
Manure. Next, let's talk about compound fertilizers. Compound fertilizer refers to the chemical fertilizer containing two or more nutrients, compound fertilizer has the advantages of high nutrient content, few side components and good physical properties, etc., which plays a very important role in balancing fertilization, improving fertilizer utilization rate, and promoting high and stable yield of crops.
But it also has some disadvantages, such as its nutrient ratio is always fixed, while the types, quantities and proportions of nutrients required by different soils and different crops are diverse. Therefore, it can be applied in combination with single-element fertilizer to get better results.
Manure. Urea is a chemically neutral fertilizer based on nitrogen. Urea is often used as a base fertilizer in compound fertilizers. Therefore, urea and compound fertilizer can not be said to be good and bad, according to different crops, different soils, different periods of choice and use.
Each fertilizer has its own suitable use period, compound fertilizer is mainly used as base fertilizer, applied before planting crops, its nitrogen, phosphorus and potassium and other components, not easy to do root topdressing! Urea is a high-nitrogen elemental fertilizer, which is generally used in the vegetative growth period of crops, such as the long leaf stage of crops, and the later recovery period of tree potential, which can be used as topdressing outside the roots and foliar spraying.
Manure. Fertilization should be done with compound fertilizer, because compound fertilizer contains nitrogen, phosphorus, potassium, nitrogen is needed for plant leaves, phosphorus is needed for plant roots, potassium is needed for plant flowering and fruiting, so compound fertilizer can supplement the nutrients needed for plant growth. Nitrogen fertilizer can be synthesized in the air by lightning on rainy days, and this is the reason why plant leaves grow green after rain.

We all know that the fruits we usually eat come from the hard work of the farmer's uncle, they need to constantly take care of the fruit tree, continuous watering and fertilization to be able to grow delicious fruits, for the nutrition that the fruit tree needs, we sometimes hear about urea from the farmer's uncle's mouthSo for fruits and vegetables, is watering urea good for fruit trees? How can we ensure the nutrition of fruit trees? So let's take a brief look at it together.
Through the above understanding, we can know that fruit trees can be watered with urea, and urea is also an indispensable organic fertilizer in agriculture, which has a certain effect and role in many agricultural activities, so I think it is okay to use urea to water fruit trees.
-
Urea is a single nitrogen fertilizer with high content, and the nitrogen of urea can accelerate the growth of fruit trees, but the use of urea for a long time will affect the taste of the fruit and reduce the taste. Therefore, it is necessary to use it together with compound fertilizer to achieve better results.
-
The use of such fertilizers is really very good, as it promotes the growth of fruit trees and prevents the occurrence of various diseases over a period of time.
-
Urea is good for watering fruit trees, urea is an organic fertilizer, which can add certain nutrients to fruit trees and promote the growth of fruit trees.
-
The vast majority of fruit trees can be fertilized, such as apple trees, pear trees, etc., however, the choice of fruit tree fertilization is generally mixed with urea, organic fertilizer, soil miscellaneous fertilizer and other fertilizers, and in the process of fertilizing fruit trees, it is necessary to cooperate with the corresponding top dressing, so as to have an immediate effect.
The common fruit trees in our lives can be fertilized, but there are differences in the time of fertilization and the choice of fertilizer to be fertilized. Apple trees are generally fertilized during the flowering period, mainly through foliar spraying, mainly with top fertilizer, and soil fertilization is usually not implemented during the flowering period. A small amount of fertilization can help fruit trees grow, increase their leaf area, improve high photocompatibility with sunlight, and extend the life of the tree's organs.
Through fertilization, the length of the flower buds to the new shoots of the fruit tree can grow quickly, so that the nitrogen absorption value of the fruit tree can reach the peak, and then the fruit tree can be successfully helped to flower and bear fruit.
In the fertilization of fruit trees, the choice of fertilizer is mostly urea, of which nitrogen fertilizer is the main, but not too much, if too much, it will be easy to appear fruit trees over-nutrition, occupancy, incomplete main branches, etc. In severe cases, it may also cause difficulties in forming flower buds of fruit trees, and flower and fruit dropping will be serious, so that it will affect the fruit tree results. Urea is usually chosen in the choice of fertilizer, because the nitrogen contained in urea is fully absorbed by fruits and vegetables, and when the nitrogen fertilizer is damp, it can make the fruit trees grow vigorously, improve the fruit setting rate in advance, and also achieve the purpose of pressing the crown.
At the same time of fertilizing fruit trees, we will choose a combination of organic fertilizer and soil miscellaneous fertilizer, through organic fertilizer as the main fertilizer and soil miscellaneous fertilizer as rot can be used for top dressing, the purpose is to fertilize fruit trees in the critical period of fruit tree growth, which can have an immediate effect. Of course, in the process of fertilizing fruit trees, it is necessary to judge whether it needs topdressing according to the symptoms of nutrient deficiency in fruit trees, and the number of topdressing should be determined according to the changes in the growth cycle of fruit trees, usually 3 to 5 times is the best. As the main fertilizing fertilizer for fruit trees, urea has a much better effect than compound fertilizer, and it is also of great help to the nutrient supplement of fruit trees.
The time of fertilization of fruit trees should generally be placed before flowering and fruiting, which can be carried out by spraying or blowing, and when fertilizing fruit trees, it should be as little as possible and fine, and it can be carried out many times, pay attention to the fact that in rainy days, there is no need to fertilize fruit trees, because of rain and thunder and lightning, additional fertilizer can be applied to fruit trees. Try to fertilize fruit trees in the spring and autumn water shortage season, and also ensure the water supply of fruits and vegetables, so that fruit trees can be supplemented with sufficient fertilizer in the process of growth and grow strongly.
In general, most of the fruit trees are in need of fertilization, but in the appropriate time and fertilization methods are different, we are best to choose urea as the main fertilizer in the choice of fertilizer, compound fertilizer can be used as additional fertilizer, chemical fertilizer to the fruit tree to bring more nutrients than urea, so on a certain basis to choose urea as the main fertilizer is the most suitable choice.
-
Fruit trees generally apply urea, diammonium phosphate, superphosphate, potassium sulfate and other compound fertilizers are better, but compound fertilizer can only play the role of supplementing nutrients, can not improve the structure of the soil, long-term simple use of compound fertilizer will cause the phenomenon of soil compaction, so when using compound fertilizer, it is necessary to apply together with organic fertilizer, that is, soil miscellaneous fertilizer is the main fertilizer, supplemented by compound fertilizer.
-
I think any kind of fruit tree can be fertilized, and it is best to choose compound fertilizer for fertilization, because this fertilizer is nutritionally balanced.
-
Apple trees, pear trees can be fertilized, urea is better, compound fertilizer is generally for crops.
-
<> fruit trees can be applied urea. Application method: dig some ditches or soil holes at a distance of 50-100 cm from the trunk of the fruit tree, and then apply urea granules directly into it, and then cover it with soil; Or you can directly dilute urea with water and spray it on the leaves and roots of fruit trees, but when diluting, you should pay attention to rather light than thick, so as to prevent root burning due to excessive concentration.
Fruit tree diseases and insect pests are more concentrated in the wintering sites of the dormant period and the early spring period, and the insect age is the same, which is convenient for concentrated annihilation, and it is the weakest period of the year, which is convenient for complete elimination. The deciduous fruit trees are all defoliated, with strong pesticide resistance, easy to spray evenly and thoughtfully, which is both pesticide saving and good. Therefore, taking advantage of the favorable opportunities in winter and early spring, combined with cultivation measures, to prevent and eliminate pests and diseases has the best effect. >>>More
