Detailed Explanation of Key Techniques for Summer Management of Pomegranate
Pomegranate is a fruit with relatively high market demand, and it is also grown on a relatively large area in China. When growing pomegranates, management work is very important. Among this, we need to reasonably adjust management methods according to seasonal changes. 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 give everyone a brief introduction. Let's take a look together!
1. Scientific Fertilization
Fertilizing young pomegranate trees in summer is very important. Generally, fertilization should be carried out once when about 1/3 of the pomegranate flowers remain and once about one month before the fruit ripens. For adult trees that have already borne fruit, in addition to the two fertilizations for young trees, fertilization should also be carried out once during the bud break stage and once during the early bud stage. In the early stage of planting, fertilizers should be mainly nitrogen and phosphorus fertilizers, and in the later stage, the proportion of nitrogen and phosphorus should be reduced while the proportion of potassium fertilizer should be increased. 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 applied should be appropriately reduced.
2. Pruning and Training
Pomegranate trees have a relatively high demand for light during growth, so in summer we must also do a good job in pruning and training pomegranate trees. Pomegranate trees should be pruned according to the principle of sparse on top and dense below in the canopy. Improve the ventilation and light penetration of the pomegranate tree, ensure normal ventilation and light transmission both inside and outside the pomegranate tree, and increase the fruiting rate of the pomegranate tree. Then, proper pinching should be carried out, shortening excessively vigorous branches and shoots, or removing the tender tips of the shoots. Finally, attention should be paid to bud removal. There should not be too many sprouts, so as to avoid competing for the nutrients needed for the pomegranate tree to bear fruit.
3. Flower and Fruit Protection
Pomegranate flowers are bisexual flowers, and there are relatively many cases of female flower abortion. Among them, 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 attention should be paid to the management of the first flush and second flush flowers of pomegranates. When pomegranate flower buds are differentiating, an appropriate spray of flower-promoting agent can be applied to promote nutrient reflux, concentrate nutrients on flowers and fruits, and also prevent excessive vegetative growth of branches. After fruit set, attention should be paid to spraying fruit-strengthening agent to enhance the water and fertilizer absorption capacity of the pomegranate tree and reduce fruit drop and fruit cracking.
4. Pest and Disease Control
The high-temperature environment in summer is very likely to trigger pests and diseases, so in summer we must also do a good job in pest and disease control. Common pests and diseases of pomegranates in summer include dry rot and peach fruit borer, etc. Pests and diseases can cause different kinds of damage to pomegranate trees, affect the flowering and fruiting of pomegranates, and reduce planting benefits. Therefore, in summer, if we find that disease has occurred, then we should use the 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 pomegranate. Summer management work for pomegranates is something we cannot ignore, as it directly affects pomegranate yield, so everyone must pay close attention to it. That is all for today's introduction.
