How to apply nitrogen fertilizer to fruits?

How to apply nitrogen fertilizer to fruits? The sweetness of fruit is determined by the amount of sugar in its cells, while the accumulation of sugar is closely related to nitrogen fertilizer. Therefore, the sweetness of fruit is related to nitrogen fertilizer. Within 28 days after flowering, the cells of young fruits are in a state of division, and the cells are full of cytoplasm with protein as the main component. After that, the cell division stopped and began to absorb water and expand rapidly, and the cell wall extended outward. At this time, the cytoplasm gradually adheres to the periphery of the cell membrane, and a large vacuole is formed in the center, which is the main place for fruits to store starch, organic acids and other substances. In the early stage of fruit ripening, the vacuole is almost full of starch and is gradually decomposed into fructose, glucose and sucrose, thus increasing the sweetness of the fruit. So, is the application of nitrogen fertilizer sweet if more fruit is used? Not exactly. If too much nitrogen fertilizer is applied, although it is beneficial to the formation of protein, it will increase the cytoplasm in the cell, delay the mononuclear phase of the cytoplasm and reduce the vacuole volume, which directly hinders the storage of starch. At the same time, too much nitrogen fertilizer will make the new shoots of fruit trees grow vigorously, consume a lot of sugars produced by leaves in the growth, thus reducing the transport to the fruit, and the sweetness of the fruit will decrease. Therefore, to improve the quality of fruit, especially the sweetness quality of fruit is not as much as people think, the more the better, the most important thing is to pay attention to moderation.
