Greenhouse structures, construction and design

Abstract

Greenhouse is a frame structure that covers transparent materials such as glass, polyethylene and polycarbonate, etc. It consists of two parts frame and covering material. The greenhouse covering material acts as a barrier to the passage of air and traps energy inside the greenhouse, which heats both the plants and the soil within it. This wall, like the air near the ground, raises the temperature within the greenhouse. Greenhouses may be used for the cultivation of high-quality fruits, flowers, various crop nurseries, ornamental and medicinal plants. The benefits of greenhouses are high production per unit area because the genetic potential of the crop can be completely exploited, vegetables and nurseries can be grown off-season that obtain high market prices, good quality products and it is easy to protect the crops from pests, diseases and extreme climatic conditions. Greenhouse farming is a highly intensive industry that needs considerable labour and capital inputs. Because of this, all factors important for a successful enterprisers should be carefully considered by potential growers. Greenhouse vegetable processing is a 24-hour commitment in several respects. Constant vigilance is required for the maintenance, crop production and handling of emergencies.
