Rural producers are aware of the importance of protected cultivation in their crops, after all, they tend to face problems every day, such as climatic factors and pests that infest their plantations. However, many are not sure how to protect them or, even, what types of agricultural greenhouse exist on the market.
To deal with the matter, we prepared a mini-guide that brings the main structures used today, in order to maintain the quality of the harvests and, consequently, offer the final consumer excellent products.
What is an agricultural greenhouse?
For some time now, producers have felt the need to protect their plants from the most adverse weather conditions, such as: frosts, snowfalls, storms, hailstorms and excessive heat or cold. Because of this, they developed agricultural greenhouses, which are structures responsible for the adjustments of light and temperature that affect various crops – vegetables, fruits, flowers, etc.
What is the importance of agricultural greenhouse?
As we said above, protected cultivation is necessary to prevent the climate and insects from devastating entire plantations and causing damage to farmers. In addition, photosynthesis processes and oxygen production are accelerated in an agricultural greenhouse. Which promotes an increase in productivity and, consequently, more excellence in planting quality.
How to set up agricultural greenhouses?
Regardless of the type of greenhouse that the producer intends to use, some precautions must be taken into account when designing the structure. See below:
In order for the cover to be perfectly firm and to support wind and weather conditions, it is recommended that the structure be reinforced. In general, the materials used to build it are galvanized steel, aluminum, or wood. It makes the system more solid.
The cover of an agricultural greenhouse is, without a doubt, the most important aspect of the structure. Although there are covers made of glass. Many producers usually opt for those made of canvas or agricultural film, which offer great results and are more affordable.
In addition to the reinforced structure and adequate coverage, it is necessary for the farmer to pay attention to the floor that he will place in his greenhouse. In general, those made of wood veneers are used. However, those produced on pressed earth are also widely used.
In order for the agricultural greenhouse to generate better results, some types of automated processes are often implemented – such as heating and irrigation systems – that aim to optimize crop production.
Agricultural greenhouses in Amherst NY usually have ventilation areas in high places, located on the sidewalls of their structures. In the case of the producer who chooses to have windows. It is advisable that they are equipped with protection screens or, even, with anti-trip meshes.
What are the types of an organic greenhouse?
There are several models of greenhouses. They all differ from each other at some point, whether in value, size, variation of sunlight, etc. In short, there are several parameters for choosing greenhouses, depending on the type of cultivation desired. Here, we will present the main types of agricultural greenhouse used in planting areas across the country. See the characteristics of each one and choose the most useful model for you:
Known for being a simple and economical model, the turbo arch agricultural greenhouse is ideal for planting low crops, such as strawberries and lettuce.
Among the types of agricultural greenhouse in Williamsville NY on the market, these are the ones with the best cost-benefit ratio. Usually, they are indicated for the horticultural sector. Because they have a greater internal spacing and high resistance to wind.
The sawtooth arch stove has upper openings along its length, which are adjustable through windows. This fact provides greater ventilation in the environment and a reduction in internal temperature. The result is savings in cooling and ventilation systems.
The chapel model resembles the construction of a church and, therefore, bears that name. The structure is ideal for places where there are many thermal contrasts. As the sloping roof has the power to prevent condensation from falling on plants. However, it is important to cover the windows with anti-trip screens or meshes in order to avoid flies and other flying insects.
The London-style agricultural greenhouse is very popular in southern Brazil. It is often used for growing various types of grapes. The ceiling is practically straight, formed by a double wire mesh that supports the plastic. In addition, the cover may have slight undulations to facilitate the flow of water.
This type of greenhouse is characterized by having a wooden structure and galvanized wire. It has a basic and very cheap structure made of vertical wooden posts connected by wires and covered by non-rigid plastic. Unfortunately, it has the disadvantage of having poor climate control as well as a ventilation system.
It has width dimensions ranging from 14 to 18 m. Due to the material, they are made of, they are unsuitable for rainy regions. This type of greenhouse also makes mechanization difficult in the interior. Parral greenhouses are more common in areas such as Almeria (Spain), West, and Algarve (Portugal).
These are typical Dutch greenhouses. They have a glass cover and windows of 2-3 panels in each 4. Their maximum opening angle of the windows is 22º (40%) and the roof width of 2 flaps is 3.2 or 4.0 m (dimensions standard ).
This type of greenhouse has straight walls as well as a Gothic arch roof. Still, on its roof, its arched structure consists of steel tubes. It should be noted that the Gothic arches have the advantage of the fact that the water from the condensation can flow better internally. Descending more easily to the sidewalls and not “spilling” on the cultures. However, the mechanical strength of the gothic arch structure is less due to its discontinuous curvature.
It is important to note that in order to maintain temperature uniformity for this type of greenhouses, the multinave presents greater difficulties, requiring good forms of heating or ventilation to maintain the same temperatures in all points of the greenhouse.
What are the advantages of agricultural greenhouses?
As you may have seen, investing in an agricultural greenhouse is essential to optimize the harvest and production of different types of crops. Among the main advantages, we can mention the following:
- products that reach consumers are better, so they end up having more competitive prices.
- control over diseases and pests is more effective, as plants grow stronger and more protected.
- harvests are guaranteed throughout the year, as the crops are not subject to changes in the climate. In addition, they can be made early, which increases the sale value of farmers.
- plants sweat less and the sun and water don’t dry out the foliage as much. As a result, the producer has significant water savings.
- the soil remains more conserved since the problems caused by the corrosion of the earth are avoided.
- the planting of seedlings can be more selective. Certain types of plants require special care that only the protection of greenhouses can guarantee.
By investing in protected cultivation, the farmer optimizes the production of his plants and increases his profits, since it ensures the quality of his products. Therefore, knowing the types of agricultural greenhouses on the market and knowing how to adapt them on your farms is something that must be done by the producer who wants to achieve excellence in his business.
