Final answer:
Flexible plastic films are advantageous in greenhouse agriculture as they trap essential solar radiation for warmth and offer a prevalent solution for regulating the internal environment, including maintaining essential gases for plant photosynthesis.
Step-by-step explanation:
Using flexible plastic films as a covering for greenhouses has several advantages, particularly for plant growth and agricultural productivity. Two notable advantages include:
- Flexible plastic films are very effective at trapping solar radiation, which is essential for maximizing plant growth. The trapped heat ensures a stable and warm environment within the greenhouse, mirroring the effects of the glass that is traditionally used. This warmth is crucial for plants, as it facilitates photosynthesis and other growth-related processes.
- Another advantage of flexible plastic films is their prevalence in greenhouse construction. These materials are commonly used because they are versatile and can create a controlled environment that is conducive to plant growth. The ability to control the internal climate of the greenhouse allows for the optimization of growing conditions for various plant species.
Moreover, these flexible plastic films play a vital role in maintaining the ideal amount of essential gases, like carbon dioxide, which plants need for photosynthesis. The ability to control the level of these gases further contributes to the growth and health of greenhouse plants.
