Top dressing of jujube trees is very important, which is directly related to the formation of yield and quality, but fertilizing jujube trees also requires know-how, and improper use can easily cause unnecessary losses. So, how to top fertilize jujube trees? Two fertilization methods to tell you!
Top dressing of roots
Root topdressing is mainly used to supplement a large number of elements, and it is also the main source of nutrients absorbed by jujube trees. After the fertilizer is dissolved, it is applied to the soil and absorbed by the root system, supplementing the nutrients required for the growth of jujube trees, and promoting the formation of growth and yield.

The nutrients required by jujube trees are different due to different growth periods, and the top dressing of jujube trees should be carried out according to different growth periods, such as before flowering, high-nitrogen water-soluble fertilizer should be used as the main fertilizer to promote the growth of vegetative branches and fruiting branches, and improve the quality of flower buds; In the fruit expansion stage, the demand for nutrients of jujube trees increases, and an appropriate amount of high-potassium water-soluble fertilizer + root burst rooting agent is applied to promote root growth, fruit expansion, increase nutrient absorption capacity, and reduce physiological fruit drop. After harvesting, balanced water-soluble fertilizer is applied to quickly restore the tree's strength, enhance cold resistance, and store nutrients for the next year's growth.
Top dressing outside the roots
Extra-root topdressing, also known as foliar spraying, to make up for the lack of nutrients absorbed by the roots, and the majority of trace elements are supplemented, which cannot completely replace the root topdressing, and the two play different effects.
It is also according to the different growth periods, different foliar fertilizers are selected for top dressing of jujube trees, such as before flowering, foliar spraying with amino acid-containing foliar fertilizers to quickly supplement nutrition and enhance stress resistance; During the flowering period, foliar spraying of potassium dihydrogen phosphate + chelated boron fertilizer increased the quantity and quality of flowering; During the fruit expansion stage, potassium dihydrogen phosphate + chelated calcium fertilizer was sprayed to promote fruit expansion, reduce physiological fruit splitting, and improve yield.
Whether it is root topdressing or extra-root topdressing, it has certain advantages for jujube trees, but it also has certain limitations. If you want the jujube tree to grow better, the two fertilization methods can be used together to achieve better results. At the same time, it should be noted that the concentration of fertilizer should be controlled for top dressing of jujube trees, and a small amount of fertilizer should be supplemented many times to give full play to the greater efficiency of fertilizer.
