How should jujube trees be fertilized? Please explain the methodsIn recent years, farmyard manure has greatly decreased, and most jujube growers have not applied organic fertilizer to their jujube trees for many years, applying only inorganic fertilizers such as nitrogen fertilizer and phosphorus fertilizer. This has led to a decrease in soil organic matter, imbalanced soil nutrients, changes in soil aggregate structure, soil compaction, and the inability of jujube tree roots to fully absorb nutrients and water, so that they cannot meet normal growth needs during the growing season. The jujube trees become outwardly strong but inwardly weak, their own disease resistance decreases, and ultimately the quality of the jujube fruit declines and profits fall. At the same time, due to changes in soil structure, the applied nitrogen, phosphorus and other elements are also adsorbed and fixed by the soil, cannot be absorbed and used by the jujube trees, and are largely wasted.
Fertilization of jujube trees should be based mainly on organic fertilizer, supplemented by inorganic fertilizer, with balanced fertilization. It is best to use soil-testing formula fertilization, which both saves costs and increases economic returns. Pay attention to the application of organic fertilizer. If farmyard manure is not available, bio-organic fertilizer can be used. In addition to containing organic matter and various other nutrient elements, bio-organic fertilizer also contains microbial strains; beneficial bacteria can activate the soil, making it loose and permeable, and improve the utilization rate of chemical fertilizers.
When farmyard manure or bio-organic fertilizer is applied as a base fertilizer, it must be applied deeply. Farmyard manure should be used together with a certain proportion of nitrogen, phosphorus and potassium fertilizers for a better effect. Later, according to the growth of the jujube trees and the fruit load, choose topdressing in a targeted way. Topdressing should be based mainly on phosphorus and potassium fertilizers and should be applied near the root system to facilitate absorption. After the jujube fruit enters the swelling stage, foliar spraying of potassium fertilizer and calcium fertilizer has a certain effect on fruit swelling and improving quality.
