In the next post, we will discuss the type of multi-tunnel greenhouse, how water is managed, in addition to the numerous advantages of using these systems and finally when the choice of a multitunnel or multilevel greenhouse is appropriate.
For a long time greenhouses have been used as a tool to increase the yield of production in different regions, mainly where the soil is not suitable for food, as these are characterized by establishing the appropriate climatic conditions for each type of cultivation and to facilitate the accommodation of a greater number of plants; They are also reusable and do not harm the environment.
Currently in the market there are a wide variety of greenhouses, which are intended to meet different needs depending on the type of crop and the available resources. An example of these is the multi-tunnel greenhouse, a structure designed for plants that require certain special care , as well as certain environmental conditions.
It is formed by a straight metallic structure that ends in curved semicircular arches, which is joined by staples, screws and nuts which is covered by a plastic film of high durability because it is added with UV protection that gives greater Usefull lifetime.
There are very different types of irrigation systems in greenhouses.
-Microaspersion: Some of the best known are the micro sprinklers, which have a range of approximately 2 meters, depending on the pressure of the type of nozzle used. You also have to pay attention to the emergent micro sprinklers, which remain hidden until the pressure of the water causes them to rise from the ground, and the closing of the water back to hide. Another type of sprinklers are the mobiles, which from the end of the hose, water the ground in which they are placed.
On the other hand, the system of irrigation in greenhouses by micro sprinklers is preferable for the sandy textures since they cover more surface and it is ideal for the irrigation of rose bushes, small flowers and small areas. – Underground irrigation and with diffusers. The system of irrigation in greenhouses of underground type is one of the most used methods at present. One of the advantages of this irrigation system is that not being exposed to air is much more aesthetic and also produces less water loss.
It is important to mention that, thanks to these characteristics it is possible to increase or decrease their size and height to adapt to different sites. Besides being a simple structure it allows to incorporate different elements of low, medium and high technology, for example, different types of ventilation , fertirrigation systems, fans, heaters and tutors for certain types of vegetables, among other tools, which allow to improve and increase the yield in the production in any scale. The management of the greenhouse brings different benefits for the producers due to its easy adaptation , This allows to withstand abrupt changes of temperature, also has the ability to resist temperatures below zero or greater than 50 degrees; being able to be in places with strong winds and dry climates without harming the plants. Multitunnel or multi-level greenhouses are characterized by having a totally metallic structure and a curved cover that can be semicircular or ogival. Its use is very widespread in technified farms, especially in those intended for horticultural production and the cultivation of flowers and ornamental plants, for its greater capacity for the control of micro climate variables. These greenhouses have natural ventilation, both lateral and frontal and overhead. -Ventilaciones lateral and frontal. -Zenital ventilation: fixed or with the possibility of controlling its opening and closing manually or with the use of engines. How is water management done in a greenhouse?
But what advantages do we find in this type of greenhouse?
It is a structure that has an important level of ventilation, with high tightness against rainwater and good distribution of light. 100% land use.
They adapt to any type of surface.
Great structural solidity High tightness to rain and air, which makes it possible to use different methods of active climate control, such as heating, ventilation, cooling or carbon enrichment systems.
It allows the complete automation of irrigation and climate control systems. Its high height facilitates air circulation and, therefore, ventilation.
The curved shape of its roof facilitates an adequate distribution of the luminosity in the interior and helps to evacuate the condensates preventing dripping on the plants.
The high strength of the structure allows, if necessary, the replacement of plastic covers with other materials (polycarbonate plates, metal sheets, sandwich panels).
Finally … when to choose multi-tunnel greenhouses?
They are designed for small areas and small-sized crops such as horticultural creeping or low-lying entutorados.Resultan be economical greenhouses, as its structure is simple and strong and makes it possible to move.
