How to prevent and control mango sunburn? A detailed guide to practical methods

Mango is a fruit that everyone loves very much. It is distributed across various tropical regions and is a typical tropical fruit. It is rich in nutrients and has the title of “king of fruits”. However, because it is a tropical fruit, some problems related to high-temperature damage also tend to appear along with it, and sunburn is one of them. Sunburn mainly occurs on the fruit and bark, causing cracking and falling off. It seriously affects yield, so how can sunburn be effectively prevented and controlled? Let's take a look below!

1. Fertilization

The fruit trees can be fertilized appropriately to enhance the tree's resistance. After harvesting the fruit, prune the fruit trees reasonably and apply sufficient fertilizer. Strengthen soil fertility and promote the growth and development of the fruit tree roots so that the roots can extend deeper and longer. This can not only prevent high-temperature damage, but also effectively resist winter freeze damage.

2. Watering

In high-temperature weather, the orchard should be watered reasonably to improve the orchard conditions. When summer is about to begin or before high-temperature weather arrives, the fruit trees should be watered appropriately. Lowering the orchard temperature and increasing moisture can effectively strengthen transpiration in the fruit trees. When the temperature is too high, water can be sprayed directly on the tree body, using artificial cooling methods.

3. Pruning

Prune the fruit trees appropriately so that they can naturally provide shade for the fruit. Pruning in the high-temperature season is different from winter pruning. The factor of shade must be taken into account. Overly long branches and leaves are themselves a very good shading tool. Therefore, reasonable pruning of fruit trees and maintaining a reasonable balance of flowers and fruit can effectively shade the fruit and reduce sunburn.

4. Planting grass

Planting green grass or Asteraceae plants in the orchard can effectively improve the soil environment and strengthen the soil's moisture-holding capacity. Green grass can also effectively lower the temperature inside the orchard and increase the relative humidity in the orchard air, which is very beneficial for cooling the fruit. It is also very easy and has almost no cost. It can also reduce sunburn.

5. Bagging

Different fruit bags can be selected for bagging treatment according to fruit size and growth conditions. The fruit bags need to be high-quality bags with strong light-blocking and water-repellent properties, and preferably ones that can refract sunlight. Otherwise, not only will the fruit be unable to set properly, but future growth and development will also be greatly affected. The bagging time should not be chosen on a sunny day; it should be done in cool weather. If the temperature inside the bag is too high, it will instead have the opposite effect.

6. Whitewashing

Whitewashing the trunk of the fruit tree is very important. Whitewashing can not only effectively prevent and control the occurrence of pests and diseases, but also reduce the incidence of sunburn. Whitewash available on the market can be mixed with substances such as quicklime water to whitewash the trunk. There are also different whitewashing methods; please refer to previous articles for details. Because white does not absorb heat and reflects light, it can greatly reduce burning.

7. Shade net

Some shading devices can be made manually by hand. For example, white cardboard can be made into a shade board at trunk height and placed around it, which can protect the trunk from sunlight and reflect it away. A layer of shade net can also be set up above the orchard and used to cover it when the sun is strongest, then removed once the sun gradually weakens.

The above seven points are the methods for how to prevent and control sunburn. Preventing and controlling sunburn is something that all tropical fruits need to pay attention to, otherwise the fruit trees may easily suffer relatively serious damage. Therefore, everyone must do a good job of strengthening orchard management in order to increase yield and enhance quality. This article is for reference only, and I hope it is helpful to everyone.
