Key Points and Detailed Methods of Pomegranate Tree Fertilization Techniques
The pomegranate was originally a fruit tree from Central Asia, and now it is gradually being cultivated in various provinces across our country. Pomegranate fruit is rich in nutrients and has a large market in our country. The pomegranate planting area is also constantly 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 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, usually applied after autumn harvest. When applying base fertilizer, attention should be paid to combining it with intertillage, fully mixing the fertilizer with the soil to improve the fertilizer utilization and conversion rate. 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 the recovery of pomegranate tree vigor. 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. Pomegranate trees mainly grow in spring, and sufficient nutrition is the foundation for ensuring that year's growth. Therefore, fertilization in spring should be mainly nitrogen fertilizer. In the early stage, pomegranate trees consume excessive tree nutrients in order to successfully overwinter. So in order to ensure sufficient nutrition, application should be done as early as possible in spring to promote the sprouting of new shoots and enhance the tree vigor of pomegranate trees.
3. Summer fertilization
Summer is the season when pomegranate trees bloom and bear fruit. During this period, the growth focus of pomegranates is mainly fruit setting. Therefore, when fertilizing in summer, we should base it on compound fertilizers such as nitrogen, phosphorus, and potassium used in spring. It depends on the tree vigor and tree age of the pomegranate tree. For example, strong-growing trees 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 supplement. Summer fertilization is to improve the flower and fruit rate of pomegranate trees, promote the growth of young fruits, and help later flower bud differentiation.
4. Autumn fertilization
After entering autumn, pomegranate fruits have 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 should be combined with pest and disease control work, and then intertillage should be 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. Therefore, 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 amount of fertilizer to prevent fertilizer damage. In particular, do not over-apply nitrogen fertilizer, which can cause excessive vegetative growth of pomegranate trees and instead reduce the fruit-setting rate of pomegranate trees. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
