The Latest Fertilization Techniques and Methods Tutorial for Pomegranate Trees
The pomegranate was originally a fruit tree from Central Asia, and now it is gradually being planted in various provinces across our country. Pomegranate fruit is rich in nutrients and has a large market in our country. Now the pomegranate planting area is also continuously expanding. When we grow pomegranates, fertilization is essential work, and topdressing is needed once every season. So how should fertilization be done? Below, the editor brings you the fertilization techniques for pomegranate trees. Let's take a look!
1. Base fertilizer
Base fertilizer is the most important fertilization application in pomegranate fertilization work. Sufficient base fertilizer is the key to ensuring healthy growth of pomegranates and improving the fruit-setting rate. Base fertilizer is generally mainly farmyard manure and compound fertilizer, and is usually applied after harvest in autumn. When applying base fertilizer, attention should be paid to combining it with intertillage, fully mixing the fertilizer with the soil, and improving the utilization and conversion rate of the fertilizer. The amount of base fertilizer directly determines the growth vigor of pomegranate trees and is closely related to pomegranate yield. Therefore, when planting, we must pay attention to doing a good job in applying base fertilizer.
2. Spring fertilization
Spring is the key season for restoring the tree vigor of pomegranate trees. In spring, the root activity of pomegranate trees increases. It is also an important period for new shoot sprouting, leaf expansion, and flower bud differentiation. In spring, pomegranate trees are mainly growing vegetatively, and sufficient nutrition is the foundation for ensuring that year's growth. Therefore, spring fertilization should mainly use nitrogen fertilizer. In the early stage, pomegranate trees consume excessive tree nutrients in order to successfully overwinter. So to ensure sufficient nutrition, fertilization should be applied as early as possible in spring to promote new shoot sprouting of pomegranate trees and enhance their tree vigor.
3. Summer fertilization
Summer is the season when pomegranate trees bloom and bear fruit. During this period, the focus of pomegranate growth is fruit setting. Therefore, when fertilizing in summer, we should base it on spring's nitrogen, phosphorus, potassium and other compound fertilizers. It depends on the tree vigor and tree age of the pomegranate tree. For example, trees with strong growth should be given less or no fertilizer, while weak trees should be given more. Summer fertilization should be carried out before the initial flowering stage, and then boron fertilizer should be appropriately applied as a foliar topdressing. Summer fertilization is to improve the flowering and fruiting rate of pomegranate trees, promote the growth of young fruit, and help later flower bud differentiation.
4. Autumn fertilization
After entering autumn, pomegranate fruit has gradually matured, but pomegranate trees are still continuing flower bud differentiation. Therefore, the nutrient consumption of pomegranate trees in autumn is very large. In autumn, fertilization is generally carried out by foliar topdressing before harvest. It is combined with pest and disease control work, and then intertillage is carried out. The fertilizer is mainly organic fertilizer, mixed with a small amount of nitrogen fertilizer. Autumn sunlight is relatively warm, and the temperature difference fluctuates greatly. So when fertilizing, we should also combine it with pruning work to enhance photosynthetic capacity, improve nutrient accumulation in the tree, help pomegranate trees overwinter, and prepare for flowering and fruiting the next year.
The above is a brief introduction to pomegranate tree fertilization techniques. When fertilizing, we must pay attention to the fertilizer amount to prevent fertilizer damage. In particular, do not over-apply nitrogen fertilizer, which can cause excessive growth of pomegranate trees and instead reduce the fruiting rate of pomegranate trees. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
