Fertilization techniques of pomegranate trees

Pomegranate was originally a kind of fruit tree in Central Asia, but now it has been gradually planted in various provinces of our country. Pomegranate fruit is rich in nutrients and has a big market in our country. Now the planting area of pomegranate is also expanding, when we plant pomegranate, fertilization is necessary, we need to top fertilize once every season. So how to apply fertilizer? The following editor has brought you the fertilization technology of pomegranate trees, let's have a look!

1. Base fertilizer

Base fertilizer is the most important fertilization in pomegranate fertilization. Adequate base fertilizer is the key to ensure the healthy growth of pomegranate and improve the rate of fruit setting. The base fertilizer is generally farm manure and compound fertilizer, which is generally applied after harvest in autumn. When applying base fertilizer, attention should be paid to the combination of ploughing and ploughing, and the fertilizer should be fully mixed with soil to improve the utilization conversion rate of fertilizer. The amount of base fertilizer directly determines the growth of pomegranate trees and is closely related to the yield of pomegranate. Therefore, we must pay attention to the application of base fertilizer when planting.

2. Fertilization in spring

Spring is the key season for pomegranate tree potential recovery. in spring, the root vitality of pomegranate tree is improved. It is also an important period for new shoot germination, leaf expansion and flower bud differentiation. Pomegranate trees grow mainly in English in spring, and adequate nutrition is the basis to ensure the growth of the same year. Therefore, nitrogen fertilizer should be the main fertilizer in spring. In the early days, pomegranate trees consumed too much nutrients in order to survive the winter successfully. Therefore, in order to ensure adequate nutrition, it should be applied as early as possible in spring to promote the sprouting of new shoots and enhance the tree potential of pomegranate trees.

3. Fertilization in summer

Summer is the season for pomegranate trees to blossom and bear fruit. During this period, the focus of pomegranate growth is mainly fruit setting. Therefore, when we apply fertilizer in summer, we should be based on compound fertilizers such as nitrogen, phosphorus and potassium in spring. According to the power and age of the pomegranate tree. For example, there is little or no application for strong trees, and more for weak trees. Fertilization in summer should be carried out before the first flowering stage, and then boron fertilizer should be applied outside the root. Summer fertilization is to improve the flower and fruit rate of pomegranate trees, promote the growth of young fruits, and help flower bud differentiation in the later stage.

4. Fertilization in autumn

After entering autumn, the pomegranate fruit has gradually matured, but the pomegranate tree continues to differentiate into flower buds. Therefore, the nutrition consumption of pomegranate trees in autumn is very large. Fertilization in autumn is usually carried out by the method of topdressing outside the root before harvest. It is combined with the prevention and control of diseases and insect pests, and then the work of intertillage is carried out. Fertilizer is mainly organic fertilizer, mixed with a small amount of nitrogen fertilizer. The sunshine in autumn is relatively warm, and the temperature difference is also relatively large. Therefore, when we fertilize, we have to combine with pruning work to enhance photosynthetic capacity, improve the nutrient accumulation of trees, help pomegranate trees survive the winter and prepare for flowering and fruiting in the second year.

The above is a brief introduction of pomegranate tree fertilization technology, we must pay attention to the amount of fertilizer when fertilizing to prevent fertilizer damage. In particular, the application of nitrogen fertilizer can not only lead to the growth of pomegranate trees, but also reduce the fruit rate of pomegranate trees. That's all for today's introduction.
