How to manage pomegranate in summer? Latest technical method tutorial
Pomegranate is a fruit with relatively large market demand, and it also has a relatively large planting area in our country. When growing pomegranates, management work is very important. Among this, we need to reasonably adjust management methods according to seasonal changes. Among them, summer management is especially important and has a significant impact on pomegranate yield. So how should pomegranates be managed in summer? Below, the editor will briefly introduce it for everyone. Let's take a look together!
1. Scientific fertilization
Fertilizing young pomegranate trees in summer is very important. Generally, when about 1/3 of the pomegranate flowers are still retained, and about one month before the fruit matures, fertilization should be applied once. For adult trees that have already borne fruit, in addition to the two fertilizations for young trees, fertilization should also be applied once during their bud break stage and early bud stage. In the early planting stage, fertilizer should mainly be nitrogen and phosphorus fertilizer, and later reduce the proportion of nitrogen and phosphorus and increase the proportion of potassium fertilizer. When fertilizing, we should control the amount of fertilizer according to factors such as tree age and fruiting rate. If the amount of fruit set is not large, then the amount of fertilizer should be appropriately reduced.
2. Pruning and shaping
Pomegranate trees have a relatively large demand for light during growth, so in summer we also need to do a good job of pruning and shaping pomegranate trees. The canopy of pomegranate trees should be pruned according to the principle of sparse at the top and dense at the bottom. Improve the permeability of pomegranate trees, ensure normal ventilation and light transmission inside and outside the pomegranate tree, and improve the fruiting rate of pomegranate trees. Then appropriately pinch the tips, shorten excessively vigorous shoots, or remove the tender tips of the shoots. Finally, pay attention to doing a good job of bud removal. There should not be too many sprouts, so as to avoid competing for the nutrients needed for pomegranate fruiting.
3. Flower and fruit protection
Pomegranate flowers are bisexual flowers, and the phenomenon of female flower abortion is relatively common, among which the proportion of complete flowers is only about 15%-20%, so under normal circumstances, the fruit setting rate of pomegranates is not very high. The flowering period of pomegranate trees is generally about 1 month. If you want to improve the yield and quality of pomegranate fruit, then pay attention to doing a good job in the management of the first and second batches of pomegranate flowers. During pomegranate flower bud differentiation, appropriately spray flower-promoting agent to promote nutrient return, concentrate nutrients on flowers and fruits, and also prevent excessive vegetative growth of branches. After fruit setting, pay attention to spraying fruit-strengthening pedicel agent to enhance the water and fertilizer absorption capacity of pomegranate trees and reduce fruit drop and fruit cracking.
4. Pest and disease control
The high-temperature environment in summer very easily triggers pests and diseases, so in summer we also need to do a good job in pest and disease control. Common pests and diseases of pomegranate in summer include dry rot and peach fruit borer, etc. Pests and diseases will cause different damage to pomegranate trees, affect pomegranate flowering and fruiting, and reduce planting benefits. Therefore, in summer, if we find that a disease has occurred, then we should use corresponding agents and new high-fat film for control according to the specific disease. Peach fruit borer can be controlled by trapping and killing methods to protect the normal growth of pomegranates.
The above is a brief introduction to summer management techniques for pomegranates. Summer management work for pomegranates is something we cannot ignore, as it directly affects pomegranate yield, so everyone must pay more attention. That is all for today's introduction.
