Definitions

  • the present invention refers to a net for protecting fruit orchards from atmospheric events, such as hailstorms, rain, wind and insect pests, a support system for rows of fruit-bearing plants comprising said net, and a method for protection of said plants against hail and pests.
  • the invention consists of a novel anti-hail and anti-insect apparatus for rows of grapevines, provided with a structure specifically designed to improve and facilitate its use with minimal encumbrance, especially for the farm machines used to operate between the rows.
  • Anti-hail and anti pest insect systems applied in farming and especially in fruit orchards and grape-growing have been known for a long time and are increasingly used, on account of changing climate conditions which lead to more frequent events such as hailstorms and invasions of aggressive pests, even in times of the year when in the past they were very rare.
  • Prior-art systems of this type consist of various arrangements, starting from the simplest ones that involve the spreading of covering nets over the plants with or without support frames on which the nets are alternatively rolled or unrolled during the periods of dormancy of the plant or when the fruit is being harvested, or when plants are being pruned.
  • frames In the case in which frames are arranged in place, they can be of two types.
  • the first type consists of vertical poles driven into the ground and crosspieces connected to the free ends of said poles to create a framework on which the nets can be spread out.
  • the nets are rolled manually above the crosspieces and tied thereto with appropriate strings or other reversible restraining means.
  • the second type consists of different structures that make it possible to lift the nets to the top of said poles, for example by means of arms jointed to a central support adapted to rotate toward the end of the pole, rolling the nets, that are tied there with said restraining means.
  • the nets can be wound around longitudinal bars that extend horizontally along the length of the rows of plants, said bars being rotated by rotatable handles connected to an end of said bars and rotated manually.
  • each net is gathered tightly in a position corresponding to the top of the support poles by the actuation of a cable running in slots or on pulleys, wherein said cable is provided along its longitudinal extension with a series of drawstrings girdled around the net.
  • This system is also provided in the vertical direction, that is on two sides of a row of fruit-bearing plants.
  • An objective of the present invention is therefore to provide a system for protection of orchards against atmospheric agents, like hail, rain, wind, sun and insect pests, which system is structurally simple and easy to manage.
  • one purpose of the present invention is therefore to provide a hail and pest protection net for orchards without the use of frame or bar supports.
  • a second purpose is a net provided with actuating mechanisms that can be operated manually or by means of farming equipment.
  • a third purpose is a net that does not require supports and cumbersome actuating mechanisms for the farm machines that till the ground and manage the plants at any height above the ground.
  • a further purpose is an apparatus for supporting rows of fruit-bearing plants comprising said net.
  • One still further purpose is a method for protection of fruit-bearing plants that comprises the above apparatus.
  • FIG. 1 is a schematic and axonometric view of a portion of a row of grapevines in a vineyard having an anti-hail and anti-pest apparatus in accordance with the invention, in a first configuration;
  • figure 2 is a schematic and axonometric view of the portion of the row of figure 1 , in a second configuration
  • figure 3 is a schematic and axonometric view of the portion of the row of figure 1 , in a third configuration

  • figure 5A is an axonometric and enlarged view of a detail of the apparatus of figure 1 in one configuration
  • figure 5B is an axonometric and enlarged view of the detail of figure 5A in a further configuration.
  • an apparatus in particular in the viticultural field as shown in figures 1-4, it is a common practice to arrange plant support structures or systems consisting of rows of poles driven into the ground so as to form rows provided with various devices for managing the growth of the plants.
  • an apparatus is indicated with letter I and has a longitudinal extension X-X.
  • poles arranged aligned with each other, driven vertically into the ground G and spaced from each other along said extension X-X.
  • the poles can consist of suitable wooden elements, or can also be concrete, metal or plastic poles having cross sections of different shapes and often provided with elements and/or devices for reversibly connecting/tensioning wire elements on the same.
  • the poles at the end of the row are shown with the reference PE (only one is shown in the figures), and the intermediate ones are indicated with the reference PI (only one is shown in the figures).
  • the head poles PE are connected with a further reinforcing pole PR through a crosspiece TR.
  • a fixed wire F called “carrying wire”
  • the head poles are appropriately braced by suitable bracing wires shown with reference FC.
  • the carrying wire F is then stretched horizontally along the length of the apparatus I and reversibly connected to support poles T supporting the vertical trunk V of the fruit-bearing plants by means of a clip C.
  • each spring compensation device 100 mounted slidably through a pair of rollers 110.
  • a pair of mobile wires FM which are placed on both sides of the intermediate poles PI, that is, on both sides defined by the apparatus. Thanks to the elasticity of the compensation devices 100, the mobile wires FM can be fixed with simple hooking operations to conventional hooking elements H, formed or applied on the relative intermediate poles PI so as to be positioned at different heights above the ground.
  • the mobile wires are also called holding wires for the growing vegetation, because the growing vegetation is held and supported in the space defined between them.
  • a single wire to be tensioned can be associated to each spring compensation device so as to have individual wires independently moved apart from each other.
  • the apparatus I just now described comprises an anti-hail and anti-pest net generally indicated with the reference numeral 1 .
  • the net 1 is a conventional net with strands interwoven so as to have openings of such a diameter as to prevent the passage of the most common pests of fruit-bearing plants.
  • the strands in the net are made with materials that can withstand weather agents and especially hail, and possibly are also capable of being at least partially a sun screen.
  • such strands are made from plastic or metal.
  • the net also has, preferably, a longitudinal extension adapted to substantially cover said extension X-X of the apparatus I; additionally, this extension is usually larger than its transversal extension Y-Y, orthogonal to the longitudinal extension of the apparatus, to cover the sides of the rows of fruit-bearing plants in both height and length.
  • the net 1 comprises at least one constant-load spring 2. This spring is fastened to the net 1 in a transversal direction, that is, along the transversal extension Y-Y of the same net.
  • the constant load spring 2 consists of a metal band or strip which, as shown in figure 5A, when it is not loaded it is rolled up on itself and comprises two ends 20, each provided with reversible means 21 for hooking onto a mobile wire FM.
  • these hooking means are folds or bends of the end of the metal strip like a hook to hang said metal strip on a mobile wire FM.
  • the hooking means can be elastic tongues formed by partially shearing said ends and folded to form a help to engage with said mobile wire FM.
  • the hooking means 21 are placed on the net 1 at each of a first 11 and a second edge 12 of the net 1 , preferably formed like a selvage.
  • the net 1 When the net 1 is mounted on a system like the one previously described, said two ends 20 of the spring 2 are each hooked to a mobile wire FM on the same side of the row. Therefore, the net 1 has a first longitudinal edge 11 , or upper edge, fixed to a first mobile wire FM1 and a second edge 12, or lower edge, fastened to a second mobile wire FM2.
  • said first 11 and second 12 edges are folded upon themselves to form a pocket (not shown in the figures) inside of which the mobile wires FM are received.
  • the two mobile wires, first FM1 and second FM2 are spaced vertically and in parallel with each other (figure 1).
  • the folding upon itself is reversibly fixed by means of securing elements (not shown) such as for example pins.
  • the net 1 can be fixed to the spring 2 even at more points along its transversal extension Y-Y.
  • the net 1 preferably includes a pocket 13 that is transversal with respect to the longitudinal extension X-X so as to reversibly receive said spring. It should be considered that the hooking means 21 project from said second transversal pocket 13 of the net 1 , so that they can be hooked freely to the above-mentioned mobile wires first FM1 and second FM2.
  • the net 1 according to the present invention is thus mounted for example in an apparatus I like the one described earlier.
  • the net 1 is illustrated in a first condition on one side of the apparatus I, wherein the second edge 12 is fastened to a second mobile wire FM2 near the ground G.
  • the second mobile wire FM2 is preferably stretched along the row by means of said elastic compensation means 100, which means are slidable on the reinforcing pole PR.
  • the first edge 11 of the net 1 is also fixed, by means of its own elastic compensation means, to a first mobile wire FM1 , above the second mobile wire, but still near the ground.
  • This condition is generally adopted when the fruit-bearing plants, and in the case in point the grapevines, are in the dormant state, and therefore in the autumn/winter season.
  • the net 1 is then gathered toward the ground so as to leave the plants free for the necessary autumn/winter managing operations, such as pruning, binding of the fruiting shoots, etc.
  • first FM1 and second FM2 are very near each other. Therefore, the net 1 , thanks to the arrangement of said at least one constant load spring 2 spaced transversally with respect to its length, is rolled up upon itself thanks to the above-mentioned relaxed condition of the net. In other words, when the spring is coiled, the net rolls up around the coils of the spring, with the effect of becoming compressed, pleating itself neatly and automatically without requiring any manual or mechanical procedure.
  • the two mobile wires, first FM1 and second FM2 are also hooked to the intermediate poles PI on the hooking means H, so as to further facilitate the pleating and the well-ordered arrangement of the net. [0036].
  • the second mobile wires FM2 are lifted from the ground G to a position just below the spur from where the fruit-bearing shoot sprouts, in the specific example of grapevines.
  • the first mobile wires FM1 are also lifted so that they cover at least the base of the sprouts. This movement is facilitated by the wheels 110 of the elastic compensation means 100 and allows the net 1 to be unrolled following the unrolling of the constant load spring 2 caused, in turn, by the increased distance between the first mobile wire FM1 and the second mobile wire FM2.
  • the first mobile wire FM1 is gradually moved upward so as to keep up with the growing vegetation and is hooked at different heights on the intermediate poles PI, while the second mobile wire FM2 remains in the position described earlier, that is, just below the spur of the fruiting shoot.
  • this repositioning causes a further, gradual and periodically controllable, unrolling of the net 1 until the top of the head pole PE and of the corresponding intermediate poles PI is reached.
  • the spring 2 allows an automatic rolling of the net 1 upon itself to obtain the smallest possible bulk.
  • the object of the present invention is not only an anti-hail and anti-pest net for fruit-bearing plants, but also an apparatus for supporting rows of fruit-bearing plants, as well as a protection method for fruiting plants against atmospheric events and pests.
  • the inventive apparatus I comprises a pair of head poles PE driven into the ground G, a plurality of intermediate poles PI driven into the ground and aligned between said pair of head poles, two first mobile wires FM1 and two second mobile wires FM2, each of which is stretched horizontally along said apparatus on each of the two sides, a pair of nets 1 extensible to cover said sides of the apparatus, wherein each net comprises a first edge 11 connected to one of said first mobile wires FM1 and a second edge 12 connected to one of said second mobile wires FM2, each of said mobile wires being moveable vertically by means of tensioning means, preferably with elastic compensation 100, slidable on said head pole, said net also comprising at least one constant load spring 2 spaced transversally with respect to the longitudinal extension of the apparatus so as to roll said net upon itself and unroll it in any vertical position along the height of said head poles and said intermediate poles.
  • the spring 2 can be spaced along all the net 1 of the row at intervals from 1 .5
  • the apparatus also comprises a fixed wire F stretched between said head poles and reversibly connected to plant support poles T by means of clips C, especially when the apparatus is used in a vineyard.
  • the elastic compensation means 100 are the ones described earlier and are mounted on a reinforcing pole PR of the head pole PE.
