Definitions
- the present invention is related to agriculture in general, in particular it relates to the irrigation methods and systems of the different agricultural crops. More specifically, it refers to a new system of rolled or gravity irrigation by channel with plastic film that aims to make water consumption more efficient and reduce water loss by filtration.
- the water moves by gravity, that is, the water slides along the slope of the grooves and does not require extra energy to give it movement.
- the quality of the irrigation depends on the principle of the systematization of the land and that is why it is very important to make a good slope in the lot to be irrigated, as well as a correct design of the grooves especially in orientation and length.
- the most traditional system of the irrigation system rolled or by gravity consists of conducting water through channels that lead the water to the cultivation plots, the water is subsequently dosed to channels perpendicular to the grooves that distribute the water in the headwaters of the plot From where water is dosed to the grooves, the water runs by gravity following the slope of the land until it reaches the end of the groove, wetting the ridges of the groove.
- a conduit pipe (hoses, PVC pipe, aluminum, etc.) is used that is located in the head of the grooves, and nozzles, valves or windows to pour the water into the furrows, which aims to prevent water loss while driving to the plots.
- Another of the disadvantages of the mentioned system is that it does not incite the growth of the plant by light reflection and does not prevent the attack of organisms harmful to the crops.
- water is applied to the soil in the form of rain using water emission devices, called sprinklers, that generate a stream of water sprayed in drops.
- the water flows through the sprinklers with pressure and reaches them through a network of pipes whose complexity and length depends on the size and configuration of the plot to be irrigated.
- One of the fundamental characteristics of this system is that it is necessary to provide the water with a high pressure upon entering the irrigation plot by means of a pumping system.
- the soil temperature does not retain moisture for the plants, does not incite the growth of the plant by light reflection and does not frighten aphids, or other organisms harmful to the plants.
- the drip irrigation system consists of applying water to a specific area of the soil, not in its entirety.
- water circulates under pressure through an extended pipe system on the surface of the ground or buried in it, finally coming out of the irrigation emitters integrated in the pipes with little or no pressure through some holes, usually of very small size.
- the present invention has as its main objective, to make available a novel irrigation system shot by channel with plastic film, which makes efficient the use and management of water in the optimum quantities in the irrigations of the different agricultural crops, without loss by evaporation and filtration , and make it easy to install.
- Another objective of the invention is to allow said irrigation system shot by channel with plastic film, which is also economical in its production, sale and installation.
- a further objective of the invention is to make available said irrigation system shot by channel with plastic film, which also allows the increase of the productivity of plants and fruits per hectare in agricultural crops.
- Another objective is to allow said irrigation system shot by channel with plastic film, which also allows the reduction of water consumption for irrigation of up to a third, compared to the traditional form of irrigation by rolling.
- Another objective of the invention is to allow said irrigation system rolled by channel with plastic film, which allows to maintain the moisture in the soil for a prolonged time that provides an environment more conducive to the growth and development of the plants.
- Another objective of the invention is to make said irrigation system rolled by channel with plastic film available, which also allows modifying the soil temperature that does more you favor the conditions for the development of the plants.
- Another objective of the irrigation system by channel with plastic film is to prevent soil erosion, also preventing its degradation and conserving healthier soils.
- Still another objective of the invention is to provide said irrigation system rolled by channel with plastic film, which also allows the control of the growth of weeds, avoiding the passage of sunlight on the surface where the film is placed, which prevents the birth and growth of weeds, and leaving all soil nutrients to crop plants.
- Still another objective of the invention is to make said irrigation system rolled by channel with plastic film available, which also allows the application and dosage of fertilizers and herbicides diluted in the water that is passed through said channel with the plastic film, which implies a significant cost savings and making it more effective.
- Still another objective of the invention is to allow said irrigation system rolled by channel with plastic film, which also incites the light fertilization of the plants and prevents the attack of harmful organisms (such as aphids) by the effect of reflective colors of the plastic film that they repel them, in case the film has reflective colors.
- Still another objective of the invention is to make said irrigation system rolled by channel with plastic film available, which also implies significant savings in fertilizers, herbicides, water, energy and labor.
- the irrigation system rolled by channel with plastic film in accordance with the present invention, consists of a plastic film with the necessary width to form a conduit channel for rolled irrigation water and with sufficient length to cover part or The entire length of the grooves in cultivation plots; said film comprising along its entire longitudinal section, distributed equidistant or not, a plurality of perforations and / or frangible sections delimited by thinning lines or by a succession of small perforations or cuts that define different shapes, which are detached to generate successive, alternate or discontinuous perforations where the water is dosed to the crop root system, depending on the type of crop and the required volumes of water; said plastic film is installed in the valleys between the groove and the groove, generating an irrigation water conduit channel and its lateral edges being buried in the sides or ribs of the groove covering all the valleys and part of the groove ribs, being crop plants in the loin of the groove.
- the film must be buried at its ends on the sides of the grooves and the width that is buried is a function of the type of soil; although preferably it goes between 2 cm. 5 cm and preferably 3 cm. of acho on each side, which ensures that the plastic is not unearthed and in the same way is easy to remove at the end of the crop cycle.
- the plurality of perforations and / or frangible sections that come off to generate the perforations dose the water in the soil directly to the root system of the cultivated plants, so that the soil is moistened evenly.
- the plurality of perforations and / or frangible sections that are detached to generate the perforations may have infinity of forms, from circular, polygonal, irregular, oval, or other diverse forms.
- the perforations and / or frangible sections that are detached to generate the perforations have a circular shape with a diameter ranging from 1 to 3.5 inches and preferably 2 inches;
- the separation distance in this mode ranges from 20cm. at 50 cm With an optimal distance between perforations of 30 cm .; in the case of the frangible sections that are detached to generate the perforations, the farmer defines the separation distance between perforations.
- the indicated dimensions are only one modality that the plastic film can present, so that the dimensions may vary depending on the amount of water that is desired to pass that depends on the type of soil, the type of crop and its water requirements.
- the width of the plastic film is a function of the measure that exists between furrows of each plot, with a sufficient clearance to create the shape of a channel that allows the passage of water on the plastic film.
- the thickness of the film also depends on the terrain on which it is applied, ranging from a thickness of 50 gauges (12.5 microns) to 125 gauges (31.25 microns). Having an optimal thickness of 80 gauges (20 microns). Although the thickness can vary depending on the type of texture and structure of the soil and the volume of water to be conducted, to avoid tearing. So that a plastic film is obtained with sufficient strength and durability in different types of terrain or provide different films depending on the type of terrain where it will be applied.
- the farmers once the film is installed, the they can detach continuously, discontinuously or alternately depending on the irrigation needs and the type of crop that is treated in such a way that the amount of water that is required can be regulated.
- the plurality of perforations and / or frangible sections that are detached to generate the perforations throughout the length of the plastic film can be practiced at the center of the transverse section of the film, in areas close to the sides, alternately between said positions or randomly.
- the perforations are carried out at the center of the cross section to allow the distribution of water in equal parts between attached grooves to reach the root system of the attached furrow plants.
- Said plastic film is preferably made of linear low density polyethylene with pigments of different colors, depending on the type of application required; although other diverse materials and compositions can be used to generate the plastic film, which can be biodegradable in the long term; but preferably it should be resistant to sunlight, chemical fertilizers, herbicides and other chemicals for agricultural use, for a prolonged period of time.
- the plastic film comprises a white or aluminum color or any other color that may reflect the light on the exposed outer face that will be against the floor and the opposite face that will be against the floor is black that prevents the passage from the solar rays to the ground to avoid the birth and growth of weeds and favors the increase of the soil temperature; at the same time it allows the reflection of light that is maintained in a range of the light spectrum which frightens organisms harmful to crops, also encourages the light fertilization of plants.
- the wavelength frequency of the even light is in the range of 400 at 700 nanometers (nm.) of the solar spectrum, which stimulates the growth of the plant and in turn helps in the control of aphids, reducing the problem of virosis.
- the plastic film is preferably installed throughout the agricultural crop cycle, so as to allow several risks and is removed manually or with recycling machinery.
- the land is prepared by making grooves with a proper inclination that allows the rolling of water by gravity along the entire channel or valley of the groove, dosing the water through the highest end of the groove.
- Water can be made to the furrows from rivers, streams, lakes, deep wells, dams or any other body of water available, using indentations, open channels, pipes and / or hoses.
- Fertilizers and chemicals can be applied at the same time, dissolved in the irrigation water.
- the humidity is maintained in the soil for a long time since the film maintains it in this way.
- the dosage of water to the root system of the crops is adequate and safe so that the perforations are never blocked and the water reaches all the plants.
- fertilizers, herbicides, etc. to the crop is much smaller because it is uniform for all plants and goes directly to the root zone of the root. Fertilizers, herbicides and other chemicals can be dissolved in water and applied through the same channel that is formed with the plastic film. The saving in this case is considerable, since the application is much more effective, the amount is reduced and can save from 40% to 50%.
- the plastic maintains the soil temperature creating an environment conducive to the optimal development of plants.
- the plastic is reflective in color, by means of the same irrigation system: it reflects sunlight at a certain wavelength to scare aphids and other organisms harmful to plants; With the reflection that the plastic has, it helps the light fertilization of the plants.
