🔷 Greenhouse cultivation 🔷
Sufficient light, air temperature during the day and night, soil moisture level and air humidity are effective in the growth of a plant and plant growth depends on these factors. Unfavorable environmental factors such as wind, storm, cold and frost prevent the growth of the plant, so in order to produce quality plants, we need an environment that protects the plant from these unfavorable conditions. Cultivation of quality plants is called greenhouse, and its products are called greenhouse cultivation. Greenhouse production requires a lot of capital, but instead, it has become one of the most profitable sectors among agricultural sectors. And in terms of the production of flowers, ornamental plants, vegetable and summer plants, they have been very successful. Also, the use of greenhouse cultivation method leads to the production of flowers and ornamental plants, as well as the production of fruits and vegetables in their off-season. find and meet the needs of people and factories, etc.
This type of cultivation in general provides the possibility to produce products that do not have the conditions for production and growth in the open space in a closed space, i.e. a greenhouse environment.

این The benefits of greenhouse cultivation 🔷
A) In greenhouse cultivation, we will have an increase in production per unit area:
The suitable environmental conditions in the greenhouse space, which is a controlled space, increase the production per unit area compared to indoor cultivation. Again, the yield will be increased up to 10 times, for example, if a product such as cucumber that is grown in the open air and in an agricultural land of the size of one square meter, has about 2 kg of cucumber as a product, while in a greenhouse of the same size It means that one square meter will have the ability and capacity of 20 kg of cucumber. Also, in greenhouse cultivation, a product like cucumber will produce three times a year, and in the case of tomatoes, it will produce twice a year. >
B) The quality of products produced in a greenhouse increases:
In greenhouse cultivation, the use of pesticides for agricultural products is reduced as much as possible, and also that products with pests and diseases are carefully investigated and controlled, and biological control methods are also used, all of which will help to increase the quality of the products, and by observing all these points, a quality product is produced. br>Production of a quality product increases exports and the product finds many fans and buyers, the environment and the earth's soil, which are very important, are also preserved.
c) Water consumption in greenhouse cultivation is significantly reduced:
In greenhouse cultivation, water consumption is reduced as much as possible for several reasons, firstly, because the space is a The space is closed, water is not wasted due to evaporation, etc., and mechanized methods such as irrigation canvas, irrigation tape, etc. are used for irrigation, which has also reduced water consumption. To better understand this concept, we will give you an example. To produce one kilo of lettuce in a greenhouse, we need 9 kilos of water, but in the open air, we need 150 liters of water to produce the same amount of lettuce.
t) In greenhouse cultivation using the hydroponic system, it is possible to plant in non-cultivable lands:
Some lands have salinity, diseases, lack of materials. There are food in the soil that has turned them into uncultivable land, but in greenhouse cultivation, with the help of hydroponic cultivation, it is possible to plant crops and consume all these crops. For example, there are greenhouses for growing vegetables in Kish.
c) In greenhouse cultivation, production does not depend on environmental conditions and it provides the possibility without air in the space. Open air and environmental and atmospheric changes provide suitable environmental conditions for plant growth and this makes us produce any product we want at any time and that we can control environmental factors and conditions and a suitable condition for Plant growth is provided, so we can produce crops in all seasons. Switching to greenhouse cultivation provides suitable employment conditions for skilled and educated people in agricultural fields, and the level of unemployment is also reduced.
