June apple topdressing technology method

July 12 01:01:58, 2024

Fertilizer is the guarantee of high quality, high yield and stable yield of apple trees. All technical measures for efficient cultivation of orchards must be based on sufficient nutrition. In the middle and the middle of June, the flower bud differentiation of apples is the peak period of the first flower. It is also the first time that the young fruit is developing rapidly. The production practice proves that the fruit trees are topdressed and given the appropriate amount of water in June every year. The fruit is obviously watered without fertilization. It is much larger, and the quality of the fruit will be greatly improved. It can also significantly change the size of the fruit trees, especially the red Fuji varieties with large results. At present, there are still few fruit farmers who are topdressing fruit trees during this period. It is a measure to increase production, increase quality and increase efficiency.


Topdressing method: Topdressing includes rhizosphere topdressing and root dressing. It should be emphasized that although foliar spray fertilizer has many advantages and is increasingly valued, it is not a substitute for soil topdressing. Because the absorption and utilization of fertilizer by leaves is limited, most of the nutrients needed for the tree still need to be supplied by soil fertilization. If the soil moisture is suitable during the topdressing of the rhizosphere, the strip application or the annular fertilization method may be adopted, and the orchard with difficulty in water supply to the drought and flood should be promoted.


The types used in top dressing are mainly phosphorus and potassium fertilizers, supplemented by nitrogen fertilizer. The amount of top dressing is the same as conventional top dressing.
