Advantages of greenhouse cultivation
Today, according to the conditions such as climate and weather changes, lack of rainfall and reduction of water reserves, many people have turned to the construction of greenhouses and agricultural lands are turning into industrial greenhouses. But why have people become interested in greenhouses? In this article, we will learn about the benefits of greenhouse cultivation and detailed statistics from the National Statistics Organization about greenhouses. In the following, we will discuss the disadvantages of greenhouse cultivation.
1- Use of minimal land to produce more products and create more jobs
In greenhouse crops, it is possible to produce crops with minimal land and high investment. This type of cultivation creates more employment compared to agricultural crops. Each hectare of greenhouse creates employment for twelve people on average. This is despite the fact that for a family’s livelihood in non-intensive crops, at least two hectares of land is needed. Considering the lack of land and the increase in population, greenhouse cultivation is introduced as a dense and economical solution in agriculture.
2- Production of maximum product per unit area
In greenhouse cultivation, precise control over all environmental factors causes maximum photosynthesis, growth, and yield of plants. In other words, creating suitable conditions in the greenhouse can increase productivity and reduce waste. For example, the yield of cucumber and tomato in the greenhouse can be up to 10 times the yield of the same vegetables in the open air conditions. Therefore, more crop production is another advantage of greenhouse cultivation. Cutting cactus with a principled and correct method
3- Off-season product production
In areas where it is not possible to grow tropical crops in winter, greenhouses seem like a suitable solution. This possibility causes the production of out-of-season products. Products such as summer fruits and tropical fruits such as bananas are available by cultivation in the greenhouse. These products are usually sold at a higher price due to their scarcity in other seasons. This action also compensates the additional costs of production and increases the income for the greenhouse owner, which is considered one of the most important merits of greenhouse cultivation in Iran.
4- Product delivery
Advancement means providing environmental conditions for plants so that the products reach the consumer market earlier than the products of open space. These products, due to their novelty, are usually sold at a higher price. For example, the cultivation of spring strawberries in short tunnels in Mazandaran province, by pre-ripening this product, makes it possible to supply it to the market 2-3 weeks earlier. Also, in Jiroft city, by growing hermaphrodite cucumbers in plastic tunnels without heating the greenhouse, these products will reach consumers sooner.
5- Adjusting the cultivation program according to market needs
Detailed planning for the cultivation of flowers and ornamental plants according to market needs can have a very effective performance. Some flowers and ornamental plants need to bloom on special days such as national holidays, during which demand and sales increase greatly. By controlling the environmental factors, the flowering time of these plants can be adjusted.
For example, azalea, which under normal conditions flowers after Nowruz Eid, by creating the right conditions, its flowering time can be adjusted in such a way that it is ready for sale on Nowruz Eid. Also, short-day plants such as chrysanthemum can be accelerated or delayed by controlling the length of day in the greenhouse. It is impossible or very difficult to set up a cultivation program in a non-greenhouse environment and it is possible at a high cost. Gardening ideas
The possibility of gardening in all seasons
One of the common problems that many gardeners face is that they cannot have the growing season whenever they want due to the season, time of year and weather changes. As a result, their production and profit will decrease.
For example, a person who wants to grow cucumbers in non-greenhouse spaces should do so in certain seasons. If one of the advantages of greenhouse cultivation is that you don’t have to worry about any of these things! With a greenhouse, you can not only control the temperature of your garden, but you can also start your growing season at any time of the year.
Increase your productivity
When you can garden in a greenhouse in all seasons, it means you can increase your plant production. As a result, your products will be more and of higher quality. On the other hand, the appropriate temperature inside the greenhouse, which is one of the advantages of greenhouse cultivation, can encourage or accelerate the growth of plants. In fact, you are free to create the perfect growing environment for any plant you want to maximize your harvest.
The possibility of choosing a place for gardening
Another benefit of growing in a greenhouse is that you can have a designated area for your gardening and growing. This allows you to grow anything from flowers to vegetables and other plants in its own suitable environment. You can also keep your gardening tools and equipment in one place and you will not need to move them constantly.
You can have multipurpose use
One of the advantages of greenhouse cultivation is that you can use it for different purposes. Thanks to the warmer and more humid environment that a greenhouse provides, you can grow fresh and organic vegetables, flowers, succulents like onions and peppers, houseplants, exotics, and more!
As long as you understand the conditions your plants or seedlings need to survive, you can plant different plants at the same time or change what you plant each year. Based on this, you can set the right time for your ideal harvest. This means that with a greenhouse, you have the freedom to choose and grow any plants you want.
Minimize production risks
Placing plants, especially sensitive plants, in a closed space prevents crops from being damaged by extreme weather-related events such as a sudden increase or decrease in temperature. It can also keep the products away from birds and other animals that may damage the products. In general, greenhouse cultivation increases the final health of crops.
Profit maximization
Studies show that one of the advantages of greenhouse cultivation is that the profit of cultivation, per product per square meter in the greenhouse can be two to three times more than planting the same product in the field. Again, when combining this method with other methods, the profit is even higher.
Plus, by using resources more efficiently in a greenhouse, you create less waste, which can turn into more profit. As another example, considering that you can create a layered mode for the greenhouse, you will be able to multiply the surface area of the cultivation and as a result grow more plants in a smaller area.
Increased stability and security
The changes in different farm conditions can have a negative effect on the plants and even the gardener and farmer and cause a lot of disruption in the cultivation process, but one of the advantages of greenhouse cultivation is that the protected environment of the greenhouse provides safe and stable conditions and the gardener’s concerns in every way Like climate changes, temperature, humidity, irrigation, etc. will decrease.
On the other hand, due to the good conditions inside the greenhouse in terms of humidity and temperature, gardeners and workers can also take care of their daily work for plants in this environment, especially in very hot or very cold seasons.
Greenhouse technology
The technology required to create climate-controlled environments inside greenhouses is also one of the advantages of greenhouse cultivation. The presence of different technologies in the greenhouse creates ideal environmental conditions for plants or different agricultural products by performing automation.
While greenhouses are primarily used to protect plants from adverse weather conditions, many large-area greenhouses offer increased yields and reduced labor and resource costs by using sensors to monitor conditions and automation to perform tasks. Simply evolved based on data. Commercial greenhouse manufacturers now have a wide range of technologies to ensure the highest level of productivity with minimum labor.
