With the increasing pursuit of the quality of jasmine tea by people, the health status of jasmine leaves has also become a focus of attention for tea farmers and consumers. During the planting process, the phenomenon of hardening of jasmine leaves occurs from time to time, which not only affects the growth of jasmine but may also affect the quality of tea. This article will delve into the reasons for the hardening of jasmine leaves and provide corresponding prevention methods.
Reasons for the hardening of jasmine leaves1. Insufficient water
The primary reason for the hardening of jasmine leaves is insufficient water. Jasmine prefers a humid environment. If the soil is dry or watering is not timely, the leaves of jasmine will lose water, leading to hardening of the leaves.
2. Insufficient sunlight
Jasmine leaves require ample sunlight for photosynthesis. If sunlight is insufficient, jasmine leaves cannot grow normally and are prone to hardening.
3. Soil problems
Poor soil, poor drainage, or high soil salinity can all lead to the hardening of jasmine leaves.
4. Pest and disease attacks
Pests and diseases such as red spiders and aphids will absorb the nutrients from jasmine leaves, leading to leaf hardening.
5. Improper application of fertilizers
Overuse of chemical fertilizers or uneven application of fertilizers can lead to the hardening of jasmine leaves.
Prevention methods for the hardening of jasmine leaves1. Timely watering
Jasmine prefers a humid environment, so it is necessary to keep the soil moist. In dry seasons, timely watering should be done to maintain soil moisture.
2. Appropriate fertilization
Reasonable fertilization, avoiding excessive use of chemical fertilizers, can involve using organic fertilizers such as chicken manure or cow dung to improve soil structure and enhance soil fertility.
3. Proper shading
In hot summers, proper shading can reduce the direct sunlight on jasmine leaves and minimize water evaporation.
4. Pest and disease control
Regularly inspect jasmine plants. Once pests and diseases are detected, take timely measures for prevention and control. You can use biological pesticides or physical control methods, such as insect nets or yellow boards.
5. Improving soil
For soil with poor drainage or high salinity, it is necessary to improve it promptly. This can be achieved through deep soil turning and adding organic fertilizers to improve soil structure.
The hardening of jasmine leaves is a common issue in the jasmine planting process. Understanding the reasons and taking corresponding preventive measures is crucial for improving the growth quality of jasmine and the quality of tea. Tea farmers should pay close attention to the growth status of jasmine leaves, promptly detect and resolve issues to ensure the healthy growth of jasmine.
