The impact of high temperatures in summer on plants, strategies for coping with high temperatures in summer, authoritative data and third-party comments.
With the arrival of summer, high temperatures are gradually becoming the norm. Many plants wilt under high temperatures, which not only affects their growth but also brings certain troubles to our daily lives. This article will analyze the impact of high summer temperatures on plants and propose corresponding coping strategies.
1. Leaf wilt
High temperatures in summer can cause excessive evaporation of water from plant leaves. If plants cannot replenish water in time, their leaves will wilt. This not only affects the aesthetics of the plants but may also severely impact their growth and development.
2. Slow plant growth
In a high-temperature environment, the metabolism of plants is affected, leading to slower growth rates. Plants that are exposed to high temperatures for extended periods will have their root and stem growth restricted.
3. Increased plant diseases and pests
High temperatures and humidity in summer favor the breeding of diseases and pests. Plants become more susceptible to diseases and pests due to reduced resistance in a high-temperature environment.
1. Choose heat-tolerant plants
When purchasing plants, heat-tolerant plants that adapt to high temperatures should be selected, such as cacti, desert roses, and agave. These plants have strong drought and heat resistance.
2. Reasonable watering
In high summer temperatures, plants require more water, but watering should be moderate. Watering too early or too late will affect plant growth. Early morning and evening are the best times for watering when the temperature is lower, and water evaporation is slower.
3. Sun shading and cooling
Setting up sun shading nets or umbrellas around plants can effectively reduce the temperature around them, decrease water evaporation, and prevent direct sunlight on plant leaves, thus lowering leaf temperature.
4. Spraying foliar fertilizer
In the hot season, plants have a higher demand for nutrients.Foliar fertilizers can be sprayed appropriately to supplement the nutrients needed by plants and enhance their stress resistance.
5. Regular pruning
In high summer temperatures, plants grow faster and should be pruned regularly to maintain good ventilation and light penetration, reducing the occurrence of diseases and pests.
According to the data from the "China Climate Change Blue Book," there has been a significant increase in high-temperature weather in recent summers in our country. It is reported that in 2019, high-temperature weather affected an area of over 5 million square kilometers in China, severely impacting agricultural production and the ecological environment.
Third-party comments suggest that to address the impact of high summer temperatures on plants, the following aspects should be considered: first, strengthening the breeding of plant varieties to enhance their stress resistance; second, optimizing irrigation technology to improve water resource utilization efficiency; third, promoting sun shading and cooling techniques to reduce the temperature of the plant growth environment.
The impact of high temperatures on plants should not be overlooked. Leaf wilt is just one manifestation. Understanding the impact of high temperatures on plants and adopting effective coping strategies are essential to ensure healthy plant growth. When selecting plants, watering, and applying sun shading and cooling, we should flexibly use various methods based on actual conditions to ensure that plants can grow robustly even in the hot season.
