What are the 5 effects of greenhouse warming agents? Greenhouse warming agents have a significant impact on agricultural practices, offering both economic and environmental benefits. Here are the five main effects: 1. **Effective Warming and Heat Retention**: One of the most noticeable effects is the increase in temperature within greenhouses. The soil temperature at 20 centimeters deep can rise by 4–6 degrees Celsius, while the average air temperature increases by 2–3 degrees. This allows for earlier planting of crops in early spring, with some crops being sown 10–15 days ahead of schedule. Fruit trees can also experience earlier germination, flowering, and fruiting, sometimes up to 10–20 days earlier. Additionally, late-season crops can have their growing season extended by over 30 days. 2. **Increased Carbon Dioxide Levels**: Greenhouse warming agents help boost carbon dioxide concentrations inside the greenhouse by 4–6 times. This not only enhances photosynthesis but also improves water use efficiency by 80%–150%. As a result, plants grow faster and more efficiently, leading to higher yields. 3. **Improved Disease Resistance and Pest Control**: Using these agents has been shown to reduce pesticide use by more than 70%, and in some cases, pesticides can be completely avoided. Instead, biological control methods are often used, which are safer for the environment and promote healthier crop growth without chemical residues. 4. **Enhanced Soil Fertility**: Greenhouse warming agents contribute to better soil health by increasing organic matter and humus content. They also promote the growth of beneficial microorganisms in the soil, improving its physical and chemical properties such as structure, aeration, water retention, and nutrient availability. This leads to stronger root systems and increased root biomass. 5. **High Economic Returns**: The use of greenhouse warming agents significantly boosts the return on investment. On average, crop yield per mu (a Chinese unit of area) can increase by 50%–60%. The input-output ratio can reach 1:20 or even higher, making it a highly profitable agricultural practice. It also encourages waste recycling and creates a sustainable cycle that supports long-term farming. These benefits make greenhouse warming agents an essential tool for modern agriculture, helping farmers improve productivity while protecting the environment.
