When is the best time to fertilize fruit trees? Matters needing attention in fertilization

When planting fruit trees, fertilization is an essential step to improve yield and quality. But at what time fertilization is fastidious, only the right medicine, in order to harvest more fruit in the harvest season. When is the best time to fertilize fruit trees? Do you know all three important periods?

First, fertilization at the young stage in spring

In the process of planting fruit trees, spring is an important period for sprouting, leaf spreading and flowering. This period includes the energy of all the life activities of fruit trees and the growth of various parts, which is in great need of a large amount of nutrition supply, which is related to the healthy growth and development of fruit trees in the later stage. So in spring, it is the first important period for fruit trees to apply fertilizer.

II. Fertilization in the early fruit stage in summer

Summer is an important period to promote flower bud differentiation, improve fruit yield and fruit appearance quality, so summer topdressing is also very necessary. According to a large number of practices, it is proved that the fertilizer time of high potassium, low nitrogen and low phosphorus is the most suitable for topdressing in summer. And the earlier the time of topdressing, the better, which is most beneficial to the growth of fruit trees.

Third, fertilization in the full fruit period in autumn

Autumn is an important period for fruit trees to store nutrients, and fertilization plays a very important role in the transition of fruit trees. Because if the fruit trees bear too much fruit or too many insect pests during the growing period, they may cause overnutrition; as a result, the nutrients stored in the trees are not enough to support the continued germination, flowering and leaf expansion in the coming year, then the overall yield and quality of the fruit trees will be affected. Therefore, 0.5% urea and potassium dihydrogen phosphate are the most suitable during the period from fruit harvest to defoliation. Spraying the whole tree once in about 10 days and operating repeatedly for 3 to 4 times can help fruit trees store nutrients and promote flowering and fruiting in the coming year.

IV. matters needing attention in fertilization

In the process of fertilization, the different characteristics of fruit trees also determine the slight differences in fertilization methods. Fruit trees with dense roots should be applied deeply, with a depth of about 40 to 60 centimeters; fruit trees with sparse roots need shallow application, and a depth of 30 to 40 centimeters is enough. When fertilizing, the fertilization area should be dominated by the projection edge and slightly distant area of the crown as far as possible, so as to maximize the effectiveness of fertilizer.

Generally speaking, when applying fertilizer to fruit trees, only when applying fertilizer at the right time can we improve the fertilizer use efficiency and increase the yield of fruit trees.
