The best 4 stages of fertilization of fruit trees

The young fruit trees in young age are mainly to develop crowns and enlarge roots to fully accumulate tree nutrients. During this period, the amount of growth was not large, and the amount of fertilizer needed was not much, but it was very sensitive to fertilizer. If malnutrition is at this stage, it will be difficult to make up even if it is doubled in the future. Applying enough phosphate fertilizer, proper application of nitrogen fertilizer and potassium fertilizer is one of the key measures for early fruiting and early yielding of fruit trees.

The results did not result in the initial stage or entered the initial stage. As the root crown continued to expand, it was necessary to maintain a relatively strong vegetative growth, and nitrogen fertilizer should account for a large proportion. During this period, it is necessary to continue to expand the canopy and promote flower bud differentiation. Therefore, phosphorus and potassium fertilizer should be added on the basis of nitrogen fertilizer application.

As a result, the adult tree in the early stage of the initial results, the main purpose of fertilization is high quality and high yield, and enhance the value of the commodity. Because the results are more and the flower bud differentiation in successive years, the proportion of phosphorus, potassium and calcium fertilizer should be increased. Therefore, fertilization should pay attention to the combination of nitrogen, phosphorus, potassium and calcium fertilizer, especially the proportion of potassium fertilizer.

After the fruit-bearing period, the tree gradually ages. In the old age, nitrogen fertilizer should be applied. The proportion of nitrogen fertilizer should be the same as that of the young tree to promote renewal and rejuvenation.

In the above four stages, it is necessary to formulate chemical fertilizers reasonably, so that scientific fertilization can make the fruit trees grow stronger, so that high-yield can be achieved, so I hope everyone can understand these four stages.
