The best four stages of fertilizing fruit trees Young fruit trees of young age are mainly the development of tree crowns and the expansion of the root system in order to fully accumulate tree nutrients. There was not much growth during this period and the amount of fertilizer needed was not much, but it was very sensitive to fertilizer. If malnutrition occurs at this stage, it will be difficult to make up for it even if it is applied later. Phosphorus fertilization and proper application of nitrogen and potassium fertilizers are one of the key measures for early fruit and early high yield.
The results of the initial period of no results or enter the initial result period, due to the continuous expansion of the root cap, to maintain more vigorous vegetative growth, nitrogen fertilizer should account for a larger proportion. During this period, we must continue to expand the canopy and promote flower bud differentiation. Therefore, phosphorus and potassium should be added on the basis of nitrogen fertilizer application.
Results The adult trees in the early stage of fruiting, the main purpose of fertilization is high-quality and high-yield, and increase the value of commodities. As the results of multiple and successive flower bud differentiation, should increase the proportion of phosphorus, potassium, calcium fertilizer, so fertilization should pay attention to nitrogen, phosphorus, potassium and calcium fertilizer, especially to increase the proportion of potassium fertilizer.
After the fruit period of full fruit period, the tree is gradually senescent. In the old age, more nitrogen fertilizer should be applied. The proportion of nitrogen fertilizer should be the same as that of saplings in order to promote rejuvenation and maintain fruitful growth.
In the above four stages, we must rationally formulate chemical fertilizers so that scientific fertilization can make fruit trees grow stronger. In order to achieve the goal of high yield, we hope everyone can understand the four stages.

Another benefit of vitamins for the human body is that it can help the growth and development of the human body to operate normally, especially for teenagers, vitamins are one of the essential nutrients in the growth process. For example, vitamin D can well adjust the metabolism of some trace elements in the human body, and can also promote the absorption of calcium by the human body, maintain bone health, and maintain a balance between the blood phosphorus level and the blood calcium level in the human body.
