Types and maintenance of greenhouses and Nethouses
Greenhouses are glass, FRP (fiberglass) Rainforced) or Ultra Violet (UV) Stabilized Transparent / Covered with Plastic Film Cover Has a translucent framed structure which is controlled Cultivation is done in respect and environment
Generally production vidha, acre of hectare The production is based on greenhouse Calculated as square feet. For this very reason Greenhouses can be given industry status today. India is a tropical country located in the arid region Datman 200 sec. Crop requirement due to increasing Depending on the standard, 20 to 30 degree. Respect in the same way Controlled while zero in Euro 2 countries Since there is less respect than there is, there is more respect 20 to 30 degree.

A greenhouse is a specific type of structure (framed). Which is covered with a transparent or translucent coating Temperature, humidity, light, carbon dioxide and ethylene Etc. Gas is regulated. Under the greenhouse Season 5 without extension as well as facilities Valuable crops can be taken. According to a research Maintaining the right amount of carbon dioxide is 28 to 30 Percentage overproduction can be obtained.
Ordinary farmer cultivates in 5 greenhouses Can start. Not necessarily that huge high Can be farmed in class greenhouses, you can take normal- Starting from the coast to the middle class small greenhouse Can. From time to time income is generated from it Increased area under greenhouse as well as facilities Can and successfully facilitate irrigation, moisture Control, control of light, control of light as well 6 to 7 times production by controlling carbon dioxide Can get.
(1) As per shape :
(A) Lean to type greenhouse :
one wall of any lined construction space is selected in such a way as tp provide adequate ventilation and reduce constuction cost.
(B) Even span type greenhouse :
this type of greenhouse is built on a fairly flat ground with a small size of the same pitch and a wide slope. Single spans are kept at a width of 3 to 5 meters, length of 3 meters and height of 2.5 to 3.5 meters.
(C) Reeds and Farrow type greenhouse :
In this type of design, two or more famed structures are attached and the rainwater slopes are disposed between the intersection.
(D) Show touch type Greenhouse :
This type of greenhouse is designed to have natural ventilation, except for ride and fur type.
(E) Corvansat type greenhouse (interlocking ridge and furrow type) :
This type of greenhouse is simpler and less expensive to construct. Pipe aching/truss and verilison are supported and polyethylene seat is used as covering.
(2) By Usage (By Indoor Environment) :
- Active heating type greenhouse
- Convection tube cooling system
horizontal air flow system: The air temperature in the greenhouse drops during the night. To protect the plants from cold, a little warm air flow is provided in greenhouse so that the effect of freezing is avoided and the growth of the unit and plants is good. Unit heaters, central heaters, radiant heaters or solar heating systems are used for heating.
Active filling type system :
- Fanpad cooling system
- Fog filling system
The temperature of the greenhouse is brought below the outside temperature for rapid growth of plants in summer. Evaporative cooling pad or fog cooling systems are used to maintain proper temperature. up to 40% of this type of greenhouse is kept open.
(3) As a creation :
- Iron structure (GI pipe)
- wood structure
- tra frame structure
