How the pomegranate tree is managed has important implications for pomegranate production. Pomegranate is a long-lived and adaptable tree species, and the fruiting period can reach more than 100 years. It is necessary to select excellent varieties and carry out reasonable cultivation management according to the requirements of the environmental conditions of pomegranate species. Let's take a look at some of the key steps in the management of a pomegranate tree.
1. Master the time to apply basal fertilizer
It should be carried out after fruit picking in autumn. The application of base fertilizer in autumn is conducive to the supply, accumulation and storage of nutrients before falling leaves, and is also conducive to the continued differentiation of flower buds and the improvement of the ratio of normal flowers, thereby improving high yield. The amount of fertilization was determined according to the results of soil and leaf analysis, as well as the topography and topography of the orchard.
2. Pull the pomegranate in time
Pulling branches is mainly for young trees, early-fruiting trees and trees and branches that are slow to release in winter. There are two main purposes of pulling branches during flowering: one is to ease the overall growth, expand the leaf area, and achieve early fruit; the other is to solve the local illumination contradiction in the crown (garden), increase the effective leaf area, enhance tree vigor, and increase yield.
3. How to gird or gird a pomegranate
Mainly for middle and old trees and trees in the full fruit period, and trees with too long stems and bare belts, techniques such as girdling, girdling, and incision are performed on the part where they want to sprout, and the purpose is to stimulate the germination of new shoots under the wound. , instead of filling the inner chamber, contributing to the three-dimensional effect. During operation, the wound should not be too wide. Generally, the width of the peeled skin should not exceed 1/15 of the diameter of the cross section of the branch. When you are not sure, try to use the method of nicking or girding.
Pomegranate pruning during flowering is also very important. It is the main measure to improve yield and quality, balance tree vigor, and enhance comprehensive resistance of the tree.
Fourth, pomegranate irrigation and drainage
Pomegranate irrigation and drainage not only affect the growth and fruiting of pomegranate, but also affect the life of the tree. Pomegranates have different requirements for water in different phenological periods. Guaranteeing the water supply in the early stage of the growth period is conducive to growth and results; in the later stage, the water should be controlled to make the pomegranate go dormant in time. There are 4 important periods when pomegranates need water: frozen water, germination water, post-flowering water and fruit-promoting water. The pomegranate tree likes drought and is afraid of waterlogging. It is necessary to do a good job in the drainage of the pomegranate garden, so that the pomegranate garden can be under the conditions of drought, irrigation and waterlogging, and can produce high-quality fruit.
5. Pomegranate bagging technology
1) Select the bag. Since the pomegranate branches are stabbed, it is necessary to choose a paper bag with high density, strong tensile force and good light protection.
2) Time. The flowering time of pomegranate is inconsistent, so bagging should be carried out in stages and batches. The better bagging time should be when the pomegranate fruit grows to the size of a walnut.
3) Method. Before bagging, spray the whole tree with a fungicide that kills peach small heartworm, then place the young fruit in the center of the bag, and then tie the bag tightly. For varieties with short stems, fasten the bag to the sprig.
4) Remove the bag. It should be carried out 1 week before the pomegranate is harvested. In order to avoid the burn of the fruit surface, the bag should be removed in the morning or evening.
