1、Usage and Dosage of Potassium Fulvic in Jujube Trees

The results showed that the application of potassium fertilizer improved water use efficiency of jujube trees, significantly promoted their growth, and increased transpiration rate and production efficiency with higher potassium application amount.

2、Optimization of Irrigation and Potassium Application for Improved

The results showed that the application of potassium fertilizer improved water use efficiency of jujube trees, significantly promoted their growth, and increased transpiration rate and production efficiency with higher potassium application amount.

3、Effects of Irrigation and Potassium Fertilizer Applications on Jujube

Application of potassium fertilizer can alleviate the effect of water deficit on fruit trees. Reasonable ratio of water and fertilizer is helpful to improve economic benefits.

4、Jujube Fertilizer: How and When to Apply

As trees mature and focus shifts to fruit, a fertilizer with higher phosphorus and potassium, such as 5-10-10 or 6-12-12, is beneficial. These ratios encourage flowering and fruit development, not excessive leafy growth.

5、Organic Fertilizers to Boost Jujube Tree Yield

Apply most organic fertilizers during early spring when trees break dormancy to support vigorous vegetative growth. Supplement with additional nutrients at critical phenological stages such as flowering and early fruit development to boost yield.

The results showed that different jujube tree varieties were adapted to different fertilization treatments, and the combination of N, P, and K could significantly improve the fruit setting rate, leaf growth, and fruit production of jujube.

Influence of Different Application Amounts of Potassium Fertilizer on

With regard to the different organs of jujubes at different growth stages, applying potassium fertilizer appropriately can effectively promote the nitrogen absorption of jujube plants, while applying potassium fertilizer excessively will curb the nitrogen absorption of jujube plants.

Optimization of Irrigation and Potassium Application for Improved

An empirical formula relating the transpiration rate and production of jujube trees to irrigation volume and potassium application amount under drip irrigation conditions were established in this study, offering guidance for irrigation and potassium application strategies in arid regions.

The combined effect of water and potassium on physiological traits of

This study examined the combined effect of irrigation and potassium fertilization on physiological traits of jujube leaves and fruit yield to determine the optimal irrigation and fertilisation strategy for its sustainable production in this region.

The Best Foliar Fertilizers for Late

In this guide, we will discuss the importance of fertilizing your jujube plant, the best fertilizers to use, when and how to apply them, and common mistakes to avoid.

Spring is a critical period for the growth of jujube trees. Applying high-potassium fertilizer during this time is essential for promoting tree growth and improving fruit quality. The following sections provide detailed guidance on how to properly apply high-potassium fertilizer in spring:

I. Selecting the Right High-Potassium Fertilizer

1. Understand Soil Conditions: Before fertilization, test the soil around the jujube trees to determine potassium levels and pH. This helps assess whether additional potassium supplementation is needed.
2. Choose Suitable Fertilizers: Various high-potassium fertilizers are available, such as potassium sulfate (K₂SO₄) and potassium nitrate (KNO₃). Select the most appropriate type based on soil test results and the specific needs of the trees.
3. Consider Slow-Release Formulations: High-potassium fertilizers often have extended release periods. Opting for slow-release or controlled-release formulations ensures a steady supply of potassium throughout the growing season, preventing soil salinty from excessive one-time applications.

II. Timing and Methods of Application

1. Optimal Timing in Spring: The best time to fertilize is around budbreak, when the trees’ nutrient demands peak. Fertilizing during this phase helps revitalize growth and lays the foundation for flowering and fruiting.
2. Application Techniques:
   • Dissolve the fertilizer in water and evenly distribute it within the tree’s canopy perimeter.
   • Alternatively, spread the fertilizer directly under the tree and irrigate to aid absorption.
3. Dosage Control: Adjust the application rate (typically 5–10 kg per tree) based on soil fertility and tree condition. Excessive use wastes resources and risks soil salinization, which can harm roots.

III. Post-Fertilization Management

1. Monitor Tree Response: Observe the trees for signs of root burning or stress. If symptoms arise, irrigate promptly and adjust future fertilization strategies.
2. Proper Irrigation: Increase irrigation after fertilization to facilitate nutrient uptake, but avoid overwatering to prevent soil compaction or root diseases.
3. Disease and Pest Control: High-potassium fertilization may influence pest/disease dynamics. Enhance monitoring and adopt preventive measures to safeguard tree health.

IV. Key Precautions

1. Prevent Fertilizer Burn: Avoid direct contact between fertilizer and tree trunks or leaves to prevent tissue damage.
2. Avoid Mixing with Pesticides: Do not combine high-potassium fertilizers with pesticides, as chemical interactions may reduce effectiveness or harm the trees.
3. Follow Product Guidelines: Always read and adhere to the manufacturer’s instructions regarding usage, dosage, and safety precautions.

spring application of high-potassium fertilizer significantly benefits jujube tree growth and fruit quality. By selecting appropriate fertilizers, timing applications correctly, managing post-fertilization care, and adhering to precautions, jujube trees can thrive with optimal nutrition, leading to healthy development and superior fruit production.
