In this article, you will be given some basic information regarding the construction of a greenhouse

A- Greenhouse structure

The width of the greenhouse is 8 meters and the length of the greenhouse is 45 meters. For this purpose, 14 openings of the greenhouse are needed. Columns should be selected from 2 galvanized pipes, 1.5 pipe bows, 1.5 pipes under the arches, 1 pipe inside the arches and 2 longitudinal pipes. The concrete foundation is a 40x40x40 cm cube.

Covering the greenhouse with three layers of plastic and the roof window should have an automatic transmission. The side windows can be folded. The entrance doors should be made of solid aluminum. The height of the longitudinal gutter should be 4 meters from the ground and the full height of the greenhouse should be 5.80 meters. The distance between the two arches is 2.5 meters and the material of the gutter should be galvanized sheet 2.5, the plastic holding parts should also be made of galvanized sheet. Long galvanized wires should be steel and 3 mm.

B- Hot air furnace

In this greenhouse, 10 hot air furnaces with a power of 170 thousand kilocalories are needed, each of which can heat 500 meters of the greenhouse area.

C- Cooling system

The cooling system must be of the type of cellulosic foam with a height of 2 meters and a width of 8 meters, with a cage holding the cellulose foam and with all the necessary equipment, with a fan of 35,000 cubic meters per hour, and the diameter of the steel impeller should be 1,200 cm. The power of the fan should be 1.5 horsepower. 5 of this cooling device is reserved.

T- Irrigation system

Irrigation of this greenhouse is drip irrigation and it needs main and secondary polyethylene pipes along with injector connections, fertilizer injection, irrigation tapes, gas valves, pressure gauge and fertilizer tank.

D- Air circulation system or circulation

For air circulation, a 60 x 60 cm fan should be installed every 25 meters, and its ventilation should be 3500 cubic meters per hour.

C. Emergency power generator

For emergency power, one kilowatt of electricity is needed for every 184 square meters of greenhouse floor. So, your generator should be between 25 and 35 KW.

C- Work supplies

To work in the greenhouse, all kinds of tools, including gloves, boots, shovels, shovels, pots, pots, scissors, buckets, work clothes, scales, and any other tools that have already been prepared, should be provided.

H- Sprayer

To spray the greenhouse, you need a Farguni sprayer, for example, a Honda engine and a Japanese or similar pump.

K- Computer and printer

A computer with a printer is also necessary for the greenhouse.

D- Office supplies

Office supplies such as desks, chairs and cupboards are needed.

Z- Machinery, wall construction and other equipment

In addition, a van and a garden tractor are needed to do greenhouse work. Also, a labor building with an area of 100 square meters with brick wall, beam roof, iron door and window, water and electricity plumbing, carpentry, service, warehouse and office will be needed. In this greenhouse, 400 meters of brick walls with a height of 2 meters are needed.

Before starting the work, one should gather the necessary information about the supply of product packaging materials, fertilizers and poisons and plant nutritional needs, fuel cost, electricity cost and water cost and prepare the necessary amount of consumables. This greenhouse needs a manager, 4 simple workers, a driver and a guard, who should have the necessary information about their rights and skills.

It is very important to visit other greenhouses and gather technical information, government and environmental laws and regulations, banking facilities, market conditions and suitable product type. It is very important to use expert, skilled and experienced staff, accurate accounting services, constant study to improve the activity and correct errors, full attention to safety, such as issues related to electrical technical devices, poisons, etc. Here, it is appropriate to say about the progress of greenhouse activity that nowadays greenhouses prepare suitable growing conditions for plants 24 hours a day and 365 days a year and can be used in different weather conditions of the countries of the world. Today, with advanced technologies and computerized and automatic systems, water, fertilizer, light, heat and humidity are provided to the plant whenever the plant needs it.

In the greenhouse, plants can be grown in pots on the ground or on platforms. Cucumbers, tomatoes, peppers, eggplants, strawberries, lettuce and other vegetables can be grown on the ground in a greenhouse. Of course, in the method of cultivation without soil or hydroponics, the plant is grown in containers in which there is water along with fertilizer and plant nutrients. In this way, the root of the plant is in the liquid. This method can be used especially for areas that do not have suitable soil, such as Kish Island.

It may be more expensive to use new systems in the initial investment, but due to the creation of very suitable and better conditions, it is economically more suitable in the long term.
