With the arrival of summer, many fruit trees begin to enter the vigorous growing season. Some fruit farmers have found that their planted plums show signs of withered leaves at noon, which not only affects the growth of plums but also reduces the quality of the fruit. This article will analyze the phenomenon of withered plum leaves at noon and provide corresponding care suggestions.
Reasons for the Withering of Plum Leaves at Noon1. Insufficient Water
Plums are fruit trees that prefer a humid environment. Insufficient water can cause leaves to wilt. In the summer, high temperatures and high evaporation rates can lead to a lack of water in the soil. If the plum's roots cannot absorb enough water, the leaves will wilt due to dehydration.
2. Excessive Sunlight
Intense sunlight in the summer can cause excessive evaporation of water from plum leaves, leading to withered leaves.
3. Improper Fertilization
Improper fertilization can also cause plum leaves to wilt. Overuse of nitrogenous fertilizer can promote excessive leaf growth, while a lack of phosphorus and potassium fertilizer can lead to poor leaf growth, resulting in withered leaves.
4. Pest and Disease Attacks
Pest and disease attacks are also one of the reasons for the withering of plum leaves. Insects like aphids and red spiders can absorb nutrients from the leaves, causing them to wilt.
Care Suggestions for the Withering of Plum Leaves at Noon1. Timely Watering
In the summer, plums require a large amount of water and should be watered timely to keep the soil moist. It's best to water in the morning or evening to avoid doing so during the high temperatures of noon.
2. Rational Fertilization
Based on the growth needs of plums, apply nitrogen, phosphorus, and potassium fertilizers appropriately. During the period of vigorous growth, the amount of nitrogen fertilizer can be increased to promote leaf growth. In the fruit maturation stage, the application of phosphorus and potassium fertilizers should be increased to improve fruit quality.
3. Shading and Cooling
During the high-temperature periods of summer, it is advisable to provide shade for plums to reduce light intensity and minimize water evaporation. Methods such as spraying water can be used to lower the temperature of the tree.
4. Pest and Disease Control
Regularly inspect plum plants and control pests and diseases in a timely manner. High-efficiency and low-toxicity pesticides can be used for spraying. It's important to alternate the use of pesticides to prevent pests and diseases from developing resistance.
5. Pruning Branches and Leaves
Timely pruning of plum branches and leaves helps maintain a ventilated and well-lit tree shape, which is beneficial for reducing the occurrence of pests and diseases and improving fruit quality.
The withering of plum leaves at noon is a common phenomenon in summer. Understanding the reasons and taking appropriate care measures can help improve the yield and quality of plums. It is hoped that this article can provide some reference value for fruit farmers.
