Importance of greenhouse site selection and construction :-
A specific type of structure that regulates the indoor environment by covering it with a transparent or translucent lid. The scientific approach of preparing vegetables, flowers and dharu in a single season is called a greenhouse. In a tropical country like India, there is often no conducive environment for crop production throughout the year. The greenhouse is a blessing in disguise for controlling adverse weather conditions such as extreme cold, extreme heat, intense light, excessive rainfall or water shortages, snowfall, strong winds as well as severe pest infestations. In this greenhouse, carbon dioxide, oxygen and ethylene gas are regulated as required. This method is initially costly} meaning only expensive crops.
A greenhouse is a specific type of structure with a frame covered with a transparent or translucent covering of plastic, polyethylene or glass in which the indoor environment can be modified according to the needs of the crop The main advantage of this is that more flowers or ornamental plants as well as vegetables can be produced from a small area for many months. Also good quality flowers can be grown. At present, greenhouse is considered as a very important organ for floriculture in Gujarat. In our state, high temperature, erratic rainfall, excessive intense sunlight as well as fluctuations in the percentage of humidity in the air have adverse effects on the crop production of flowers. In such a heterogeneous situation, good quality pathogen free flowers can be obtained by controlling the indoor environmental factors through the greenhouse. The price of flowers in winter season is much lower than in summer season. So’that inthe summer season, by
cultivating the flowers of cutiiowers through thegreenhouse, the price can be obtained and more foreign exchange can be obtained by exporting abroad.
