  • the very fine meshes furthermore serve to prevent the egress of vegetation (epicormic shoots) between the meshes, which could weaken the net 4.
  • the black color reduces or eliminates the effect of UV rays on this first band 21 which, with the net 4 in the extended position, is arranged horizontally and thus is the one most exposed to UV rays.
  • the black color of this first band 21 also makes the apparatus less visible from above, thus reducing its environmental impact.
  • the second band 22 is preferably white.
  • the function of this second band 22 is to provide the plants with light, but, with its fine meshes, obstruct the passage of new vegetation.
  • the third band 23 is preferably also white.
  • This third band 23 coarser than the previous one, extends, with the net 4 in the extended position, substantially parallel to the side of the plants. For this reason, this third band 23 does not have problems for the insertion of new vegetation and it is affected by degradation from UV rays to a lesser extent, since one side will always be in the shade over the course of the day.
  • the size of the meshes of this third band 23 depends on the plants cultivated, and the phytophagous insects and the diseases from which one wants to protect the plants.
  • the fourth band 24 is preferably black.
  • the function of the color and fine meshes of this fourth band 24 is to combat the growth of weeds with an effect similar to that of mulching.
  • the fourth band 24 terminates in an edge or selvedge region 24a.
  • These bands 21, 22, 23 and 24 can vary depending on the species of plant to be protected and on the goal of protecting and controlling the growth of the plants, which will be better detailed below.

  • the anchoring means 105 comprise through holes 115 which are defined in the net 104 and which are mutually spaced apart so as to correspond to the spacing of the poles 102 so that the net 104 can be fitted, by means of these holes 115, over the poles 102 so that the upper end of the net 104 rests on the top wire 103 which, in this embodiment, passes through the poles 102 in a region that is spaced downward from the tip of the poles 102.
  • the retention means 106 comprise a plate 116 which can be fixed to one side of the pole 102, for example by means of a U-shaped clamp 108 which, together with the plate 116, surrounds the pole 102 and which is fastened by way of a pair of nuts 109 so that the plate 116 is stably fixed to pole 102 above the top wire 103 and thus above the net 104.
  • the plate 116 defines first engagement regions 113a and 113b and second engagement regions 114a and 114b, mutually spaced apart vertically, for the ends of the retention elements 112a and 112b.
  • the plate 116 is provided with two lower hooks 117a and 117b, and each one of these engages an end of a retention element 112a and 112b, constituted by a chain.
  • the plate 116 is arranged above the upper end of the net 104 and the retention elements 112a and 112b, in the rest position, are hung up with their upper end on the plate 116 and descend by gravity, passing, through the hole 115 of the net 104 fitted over the pole 102, between the net 104 and the pole 102, as illustrated in particular in Figure 11.
  • the same plate 116 is provided with two upper hooks 118a and 118b, each one of which can engage the other end of the corresponding retention element 112a and 112b, after the latter has been wrapped, from the inside outward, around the corresponding flap 104a and 104b of the net 104 in the gathered position so as to retain it in such gathered position, as illustrated in particular in Figure 12.
  • the hooks 117a, 117b, 118a and 118b for hooking the two ends of the retention elements 112a and 112b can be provided on two separate plates which are fixed to the pole 102 at mutually different heights.
  • other retention means such as for example belts, chains or ties for keeping the net 4 in the gathered position during winter.
  • the net 104 can be provided substantially like the net 4 of the apparatus in the first embodiment, with the difference that, in the intermediate band 21 of the net 104, conveniently reinforced, the holes 115 are defined which make it possible to fit the net over the poles 102.
  • the net 104 for the apparatus according to the invention in the second embodiment is illustrated in Figure 13.
  • the elements of the net 104 that correspond to the elements of the net 4 described previously with reference to the first embodiment of the apparatus have been marked with the same reference numerals.
  • detachable means are provided for fastening the lower end of the net 104 proximate to the ground. These means are not shown since they are very similar to those previously illustrated and described with reference to the first embodiment.
  • each hole 115 can be edged by way of a ring plate, not shown, fixed to the net 104.
  • the installation of the apparatus according to the invention is very simple. First the poles 2 and 102 are erected, or pre-existing poles are used if these protrude sufficiently above the row of plants to be protected. Subsequently, the top wire 3 and 103 is placed under tension and is spaced downward, for example at a distance of 20-30 cm from the tip of the poles 2, 102. At this point, the net 4 is impaled between the spikes 2a and the second wing 7b of the plates 7 that cover the upper end of the body 2b of the poles 2 (first embodiment), or the net 104 is fitted, with the holes 115, on the poles 102 (second embodiment) and laid on the top wire 3 and 103.
  • the net 4 and 104 When the net 4 and 104 has to perform its task of protecting the row, it is arranged in the extended position along the sides of the row and fastened, with its lower end, to the fastening means 30, as shown in Figures 1, 3 and 11. When, on the other hand, it is necessary to gain access to the plants and/or when the protective function of the net 4 and 104 is not required, the latter can be brought to the gathered position and held in this position by way of the retention means 6 and 106, as shown in Figures 2, 4 and 12. It should be noted that, with the apparatus according to the invention, the net 4 and 104 can be gathered on one side only of the row, as illustrated in particular in Figure 5.
  • the net 4 and 104 by way of the spikes 2a or by way of the holes 115, is stably anchored to the poles 2 and 102, an excellent strength is obtained in supporting the net 4 and 104 under any meteorological conditions, for example in hail, high winds, snow and ice, without the need for installing pole covers or for stitching the net 4 and 104 to the top wire 3, 103 since it is the poles 2 and 102 themselves that keep the net 4 and 104 centered and in place.
  • the average time required for the operation of opening and closing the net is indicatively approximately 2-3 hours per hectare, against the 50-100 hours required by conventional apparatuses. These reduced times make it even more convenient to apply the apparatus to crops that require multiple harvesting passes or multiple manual thinning passes, such as for example drupaceous plants and some types of pomaceous plants. Furthermore, in some cases, it is possible to halve the time by uncovering only one side of the rows.
  • the apparatus according to the invention also offers an effective anti-insect action by interposing a physical barrier between the plant and the outside world which impedes the biological cycle of all phytophagous insects with a wing size greater than 3-4 mm, such as for example cydia, pandemis, capua, eulia, orgyia, wood leopard moth, fruit fly, and others.
  • the apparatus in question also has an effective anti-fungal action since the spores that originate from the outside, when the net is in the extended position, are for the most part electrostatically attracted by the net itself and thus cannot reach the fruits or vegetation of the plants.
  • the apparatus in question also limits the excessive growth of new vegetation (epicormic shoots) which, by consuming most of the nutrients, would penalize the growth of the fruits.
  • a further function of the apparatus in question is that of being capable of being used to control the number of fruits grown by the plants so as to obtain larger fruits, particularly in apple growing.
  • the apparatus in question, during the pollination of the flowers by insects, which takes place over several days, it is sufficient to keep the nets gathered in (closed) for a preset number of days and then to proceed to extend (open) them so as to prevent the protraction of the pollination, thus limiting the number of flowers pollinated and thus the number of fruits.
  • the apparatus according to the invention represents a true integrated production system with advantages that include higher productivity, making it possible to control the growth of the plants, increasing the production of fruit buds, and reducing interventions with plant protection products.
  • Another advantage of the apparatus according to the invention is that it requires fewer passes, between the rows, of works vehicles, resulting in a higher fertility of the soil, since with fewer passes of heavy machinery there is less compaction of the soil, less consumption of fuel, and the use of fewer machines for the same achievable results.
  • the apparatus according to the invention also ensures an effect against spring frosts in that the net in the extended position hinders the dispersion, at night, of the heat accumulated during the day.
