उत्तर
A greenhouse is a closed facility used to grow fruits and vegetables. Its framework supports a translucent outer shell made of glass or plastic. It is a sheltered area where environmental conditions can be controlled to promote optimal plant development.
Farmers are increasingly using the greenhouse approach because it allows them to quickly harvest fruits and vegetables without worrying about unpredictable weather conditions.
The main advantages of the greenhouse to the farmers are:
- The greenhouse coverings have the ability to modify the direction of the sun's rays, resulting in an even. distribution throughout the entire surface, benefiting the entire greenhouse and avoiding direct solar rays falling on the plants.
- Farmers can manage and establish the ideal cultivation environment in a greenhouse. This enhances productivity.
- Greenhouses help protect crops from pests, vermin, and illnesses, lowering the risk of crop failure.
