RO125496A2 - Modular textile coverings for protecting and mulching plants - Google Patents

Abstract

The invention relates to a covering used for protecting agricultural crops and soil against excessive insolation, insects, birds, hail stones, rain showers, wind gusts, cold and for protecting the soil in the cultured area against weeds and evaporation loss of water. According to the invention, the covering is a modular textile confection made of textile material and/or textile composite made of polyethylene stabilized to the action of ultraviolet radiations.

The present invention relates to textile coverings for the protection of agricultural crops against excessive insolation, insects, birds, hail, rain showers, gusts of wind, cold and for the protection of the soil in the cultivated area (or mulching) against weeding and dehydration by evaporation.

It is known that the protection of agricultural crops against the mentioned bioclimatic factors is achieved worldwide with the help of knitted or woven fabrics of shading, with varying degrees of coverage, between 30-95%, made of monofilament yarns of polyester, high density polyethylene or polypropylene, supported on metal skeletons in the field or inside greenhouses.

Among the patents recently developed worldwide are: WO 9525424; WO 9726419; KR20040072192; JP 2007089558; US 5497537 showing technical solutions and accessories for attaching shading-anti-hail textiles on metal profile skeletons or on cables, in the form of pieces of fabric, without being made; for soil protection or mulching (JP 2007089558) a nonwoven provided with perforations was used for planting rhizomes and other plants. The OSIM database does not include textile coverings, nor shading, anti-hail, anti-insect fabrics.

The technical problems solved by the invention consist in the design of technical textile garments in the form of low (or high) tunnels, supported on specially designed metal arches, to protect agricultural crops from excessive insolation, insects, birds, hail, rain showers, gusts of wind, cold, depending on the type of textile material from which they are made; the joints of the cut pieces can be made optionally through different variants: sewing with polyester technical thread, thermal welding, ultrasonic welding, with high frequency or induction currents, etc.

The plant protection covers consist of the cover itself, which also includes a part called the steering wheel, with a width of 200-300 mm, which is covered with earth, to prevent the penetration of insects or animals from the outside, together with the two end caps. , which close the cover over the agricultural crop, forming a textile enclosure in which the plants can

0—21) 0 8 - 0 0 8 8 6 - 1 4 -11- 2008 develop well, sheltered from the unfavorable factors mentioned; the dimensions of the supporting arches determine the dimensions of the textile covers, which can be incorporated or attached to the arches. Optionally, the roofs are provided with access openings for maintenance work.

For mulching the soil in the cultivated area, in order to protect it from weeding and dehydration by natural evaporation, flat technical textile garments have been designed, consisting of three strips, through which the combination with velcro zipper, staples, tridents, buttons, etc., at intervals with a determined length, except for some parts around the plant stems, the cultivated surface is covered on two rows of plants, physically preventing the development of weeds, without preventing the transfer of water and air to the soil. The central strip has the corresponding dimensional width with the distance between the rows, to which 5 cm is added bilaterally.

The modular character of the textile covers refers (non-exclusively) to their length, as a multiple of 5 m.

Example:

Modular cover for plant projection supported on built-in metal arches with dimensions 900x900x1100 mm, distance between arches 900 mm, made of fabric made of monofilament polyethylene yarn stabilized by UV radiation, with 45% coverage, which corresponds dimensionally to protect potato crops , peppers, etc.

Claims (2)

^ -2008-00886-1 4 -11- 2008 CLAIMS: 1. Modular textile coverings for the protection of plants supported by attachment or incorporation on specially crafted metal arches, which are technical textile garments in the form of low or high tunnels to protect crops from excessive sunlight, insects, birds, hail, rain showers, gusts of wind, cold, depending on the type of textile material from which they are made, namely fabrics, knitwear, textile composites, consisting of the cover itself, which includes a part called the steering wheel that is covered with earth, two terminal covers, optional access openings for carrying out the maintenance works and joints of the cut parts made by sewing with polyester technical thread, thermal welding by contact with a heated / hot air surface, ultrasonic welding, with high frequency currents, induction, etc. 2. Modular textile coverings for mulching the soil in the cultivated area, in order to protect it from weeding and dehydration by natural evaporation, which are flat technical textile garments, consisting of three strips, through which the combination of velcro zipper, staples, tridents, buttons, etc., at intervals of a certain length, except for parts around the plant stems, cover the cultivated area on two rows of plants, physically preventing the development of weeds, without impeding the transfer of water and air to the soil, noting that the central strip is wide corresponding dimensional with the distance between the rows, to which 5 cm are added bilaterally.
