Abstract:

By analyzing the distribution and utilization characteristics of nutrient elements in apple trees, the variation of nutrient content in roots, branches, leaves and fruits of apple trees at different growth stages and the existing fertilization technology of apple trees, the demand range of different nutrient elements in different parts of apple trees at different growth stages and the technical basis of formula fertilization of apple trees were clarified in this study. It was suggested that the nutrient content and proportion of different parts of fruit trees should be combined with the development of fertilizer formula to develop special formula fertilizer more suitable for apple trees, and more efficient fertilization technology should be used to apply fertilizer reasonably and accurately, reduce fertilizer loss, and improve fruit quality and yield and fertilizer utilization efficiency.

Key words: apple tree, nutrient element, annual cycle change, formula fertilization technology, research progress
