Choosing an appropriate site environment to avoid the construction of a site with high PH value, soil viscosity, easy to build, high groundwater level, and salty alkali, and create a good ecological environment conducive to the growth of apple trees, but also pay attention to choose Anti-yellowing rootstock is good.

The application of organic fertilizers to improve soil physical and chemical properties of soil organic matter has a significant role in promoting the activation of iron, the amount of organic matter directly affects the content of available iron. Increasing organic fertilizer can also improve soil structure, prevent soil compaction, and increase the content of available iron. Therefore, the application of organic fertilizer is an important measure to improve ferric nutrition, and it is also the fundamental method for controlling iron deficiency in apple trees.

There are many ways to apply iron fertilizer to iron fertilizers. What methods should be used not only to consider differences in site conditions, but also to see the results of apple trees and the age of trees. 1 Application of iron fertilizer: combined with autumn basal fertilizer, 0.15 kg to 0.2 kg of ferrous sulfate is mixed in each organic fertilizer. This method is best not used in alkaline heavy orchards so that the iron element is not cured and cannot be absorbed by the root system. 2 Foliar application of iron fertilizer: During the growth of fruit trees, the leaves are sprayed with 0.3% to 0.5% of ferrous sulfate and iron citrate. Generally, they are sprayed once every 10 to 15 days and sprayed continuously for 2 to 3 times. If foliar iron fertilizer is used on the result tree, organic iron fertilizer should be selected as far as possible to avoid unclean fruit surface. Three dry injections: The opponent’s lack of iron results in a heavy tree. The most commonly used and most effective one is the injection of 0.15% to 0.1% ferrous sulfate solution to the stem.
