JP 2001-302407 A (Abstract, FIGS. 1 and 2)

  In the case of the spraying method disclosed in Patent Document 1, a drug can be supplied to the outer surface of a crop or the like. However, when this spraying method is applied to trees where leaves, branches or fruits are present, spraying the drug only from the outside of the tree is sufficient to apply the drug to the backside of the leaves, branches or fruits and to the inner area of the tree. Difficult to supply to. Moreover, when this spraying method is applied not only to chemicals but also to fertilizer, air, or water, it is difficult to sufficiently supply the fertilizer, air, or water to the inner region of the tree.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a spraying method capable of reliably supplying chemicals, fertilizers, air or water to leaves, branches or fruits of trees. It is what.

  In order to solve the above problems, the present invention is a spraying method for spraying a drug, fertilizer, air or water to leaves, branches or fruits of a tree, and spraying the drug, fertilizer, air or water from the outside of the tree. A flexible tube with a plurality of tube spray nozzles in the tube length direction at least in the tube side direction is placed over the trunk and branches of the tree, and medicine, fertilizer, air or water is placed in the flexible tube. It is pumped and sprayed with chemicals, fertilizer, air or water from the inside of the tree through the tube spray nozzle.

  When such a method is adopted, chemicals, fertilizer, air or water is sprayed from the outer jet tube arranged outside the tree, and a flexible tube having a plurality of tube spray nozzles is spread over the tree. Since the medicine, fertilizer, air, or water is sprayed from the inside of the tree, the medicine, fertilizer, air, or water can be sprayed to the tree from both the outside and inside of the tree. In particular, chemicals, fertilizer, air, or water sprayed from the inside to the outside of the tree falls from the outside to the inside due to gravity. Therefore, it is possible to spray chemicals, fertilizer, air or water even on portions where the chemicals, fertilizer, air or water are difficult to reach in the backside of the tree. As a result, it is possible to reliably supply chemicals, fertilizers, air or water to the leaves, branches or fruits of the tree.

  Further, in addition to the above-described invention, another invention is such that the tube spray nozzle is provided so as to be rotatable in the circumferential direction of the flexible tube, and the spray direction of the medicine, fertilizer, air or water can be adjusted. To do. When such a method is adopted, it becomes possible to more reliably spray the chemical, fertilizer, air or water to the portion where the chemical, fertilizer, air or water is difficult to flow in the backside of the tree.

  Further, in addition to the above-described invention, another invention is configured such that the head of the spray nozzle for tubes can be swung with respect to the spray nozzle for tubes, and the spray direction of the medicine, fertilizer, air or water can be adjusted. To do. When such a method is adopted, it is possible to spray chemicals, fertilizers, air or water on a desired part of the tree. Therefore, it is possible to more reliably spray the chemicals, fertilizer, air or water to the part where the chemicals, fertilizer, air or water do not reach the backside of the tree.

  According to the present invention, chemicals, fertilizer, air or water can be reliably supplied to the leaves, branches or fruits of trees.

  Hereinafter, a spraying method according to an embodiment of the present invention will be described with reference to the drawings. Moreover, in embodiment of this invention, the case where the spraying method of a chemical | medical agent, a fertilizer, air, or water is applied to the mango tree 10 planted in the pot 12 is demonstrated as an example.

  FIG. 1 is a side view of a mango tree 10 to which a spraying method according to an embodiment of the present invention is applied.

  As shown in FIG. 1, mango trees 10 are planted in pots 12 one by one. The pot 12 may be made of earthenware or plastic. The bowl 12 is used to make it portable. In the pot 12, soil for trees such as Kanuma soil is placed.

  The mango tree 10 has a trunk 14 and a plurality of branches 16 separated from the trunk 14. During the fruit season, the branch 16 has many fruits 18. The branch 16 has a large number of leaves 20. In order to protect the mango tree 10 from diseases and pests, it is necessary to spray the mango tree 10 with a drug suitable for preventing the disease and controlling the pests. In addition, when it is appropriate to absorb the fertilizer from the leaf veins 20 of the mango tree 10, it is necessary to spray the fertilizer on the mango tree 10. Further, when the pollen of mango flowers is scattered for pollination, it is necessary to blow air on the mango tree 10. Furthermore, when the relative humidity of the outside air is in the range of 30% or more and 50% or less, mites, insects, and molds are unlikely to be generated.

  For the above reason, the outer jet tube 21 is disposed above the mango tree 10, and the flexible tube 24 that can be bent is wound around the mango tree 10. The outer jet tube 21 is arranged on the head of the mango tree 10 arranged in a plurality of rows so as to correspond to each row. At least a side surface of the outer jet tube 21 is provided with a plurality of tube spray nozzles 22 in the length direction of the outer jet tube 21. The tube spray nozzle 22 can swing in the circumferential direction of the outer injection tube 21. By adjusting the angle of the tube spray nozzle 22, the mango tree 10 can be supplied with chemicals, fertilizer, air or water (hereinafter referred to as “medicine etc.” as appropriate).

  The flexible tube 24 is wound from the trunk 14 of the mango tree 10 to the tip of each branch 16 (see FIG. 1). Note that placing the flexible tube 24 over the mango tree 10 includes arranging the flexible tube 24 along the branches 16 in addition to winding the flexible tube 24 around the mango tree 10. At least a side surface of the flexible tube 24 is provided with a plurality of tube spray nozzles 48 in the length direction of the flexible tube 24. However, the tube spray nozzle 48 may be provided not only on the side surface of the flexible tube 24 but also at one end.

  FIG. 2 is a schematic view of a system for spraying medicines and the like on a plurality of mango trees 10.

  This system is connected to a tank 44 containing medicine, a pressurizing pump 40 connected to the tank 44, a plurality of solenoid valves 36 connected to the pressurizing pump 40, and the solenoid valves 36, respectively. A main tube 34, a flexible tube 24 branched from the main body tube 34 for each pot 12, and an outer jet tube 21 arranged on the head of the mango tree 10 for each row of mango trees 10 arranged in parallel. ing. The electromagnetic valve 36 and the main body tube 34 are provided by the number of rows in which the plurality of bowls 12 are arranged. The tank 44 and the pressure pump 40 are connected by a pipe 42. The pressurizing pump 40 and the electromagnetic valve 36 are connected by a pipe 38. A portion branched from the pipe 38 to each electromagnetic valve 36 and a portion branched from the main body tube 34 to the flexible tube 24 are branched by a joint pipe 37. The outer jet tube 21 and the tube 38 are connected by a tube (not shown). The tank 44 is filled with a medicine or the like. By opening and closing the electromagnetic valve 36, a drug or the like can be sent to the main body tube 34 under pressure. The pressurizing pump 40 is a pump for applying a predetermined pressure to the medicine or the like and sending the medicine or the like to the main body tube 34, the flexible tube 24, or the outer jet tube 21. The solenoid valve 36 is connected to a control device (control panel) (not shown), and the solenoid valve 36 is opened and closed by an operation in the control device. However, instead of the electromagnetic valve 36, an air valve or a manual valve may be used. Alternatively, at least one of the tube 42, the tube 38, and the main body tube 34 may be a flexible tube that can be bent.

  Next, the configuration of the flexible tube 24 and the tube spray nozzle 48 will be described.

  FIG. 3 is a view for explaining the configuration of the flexible tube 24 in FIG. 1.

  As shown in FIG. 3, the flexible tube 24 branches from the main body tube 34 into a plurality. The main body tube 34 and the flexible tube 24 are, for example, flexible tubes having a circular cross section. The main body tube 34 and the flexible tube 24 are connected by a joint pipe 39. The joint pipe 39 is a tubular joint that branches in three directions. The distal end 25 of the flexible tube 24 is closed without opening. Further, a plurality of tube spray nozzles 48 for spraying a medicine or the like are provided in the side surface direction of the flexible tube 24 in the length direction thereof. The plurality of tube spray nozzles 48 can be provided, for example, at intervals of 60 cm, but the intervals are not limited to the dimensions. Further, a tube spray nozzle 48 may also be provided at the tip 25 of the flexible tube 24. As a material for the flexible tube 24, a general-purpose resin such as polypropylene resin or nylon resin can be suitably used. The tube spray nozzle 48 is provided in a straight joint 49. The straight joint 49 is connected via a tube 47. That is, the flexible tube 24 is configured by the straight joint 49 and the tube 47. The tube spray nozzle 48 has a head 52 at a position protruding in a direction substantially perpendicular to the longitudinal direction of the flexible tube 24. The head 52 is provided with a discharge port 50 for spraying medicine or the like. The tube spray nozzle 48 is rotatable in the circumferential direction of the flexible tube 24 by rotating a straight joint 49 in the circumferential direction of the flexible tube 24. A cap nut 49 a is provided at both ends of the straight joint 49, and the straight joint 49 and the tube 47 can be connected by tightening the cap nut 49 a. After loosening the cap nut 49a and rotating the straight joint 49, the head 52 can be freely adjusted by tightening the cap nut 49a again.

  Next, a method of spraying a medicine or the like on the mango tree 10 using this system will be described.

  First, the flexible tube 24 is wound around the mango tree 10 planted in each pot 12. The flexible tube 24 is preferably wound so as to reach the tip from the base portion of each branch 16. Next, the tube spray nozzle 22 is rotated in the circumferential direction of the outer jet tube 21 and the tube spray nozzle 48 is rotated in the circumferential direction of the flexible tube 24 to adjust the direction in which the medicine or the like is discharged. As a result, it is possible to disperse medicines and the like from the outside of the mango tree 10 and to disperse medicines and the like from the inside of the mango tree 10 to a desired portion.

  Next, a controller (not shown) is operated to drive the pressurizing pump 40, and then the electromagnetic valves 36 in a predetermined row are opened. When the electromagnetic valve 36 is opened, the medicine in the tank 44 is pumped to the main body tube 34. Further, the medicine or the like in the tank 44 is also pumped to the outer jet tube 21. The drug or the like that is pumped to the main body tube 34 passes through the flexible tube 24 from the main body tube 34 and exits from the head 52 of the tube spray nozzle 48. On the other hand, the medicine or the like sent from the tube 38 to the tube (not shown) passes through the outer jet tube 21 and exits from the tube spray nozzle 22. It is preferable to spray the medicine or the like every predetermined time by changing the pressure of the pressurizing pump 40 or switching the opening and closing of the electromagnetic valve 36 every predetermined time. On the other hand, while the electromagnetic valve 36 is open, the medicine or the like may be continuously sprayed on the mango tree 10 under a constant pressure by the pressurizing pump 40. In that case, a predetermined amount of medicine or the like corresponding to the length of the period during which each electromagnetic valve 36 is open is sprayed on the plurality of mango trees 10 in each row. The drugs herein include those for the purpose of controlling and controlling insect pests as well as those for preventing and treating tree diseases.

  In the above-described method for spraying medicines and the like, a flexible tube having a plurality of tube spray nozzles 48 while spraying medicines and the like from the outer jet tube provided with the tube spray nozzles 22 arranged outside the mango tree 10. Since 24 is wound around the mango tree 10 to spread the medicine and the like, the medicine and the like can be spread from both the outside and the inside of the mango tree 10. In particular, since the medicine can be sprayed also from the inside of the mango tree 10, the medicine etc. can be reliably applied to a portion of the mango tree 10 where the medicine etc. are difficult to travel such as the fruit 18, the branch 16 or the back side of the leaf 20. Supply is possible. Further, since the flexible tube 24 is wound so as to extend from the root portion of the branch 16 of the mango tree 10 to the tip, it becomes possible to supply medicine or the like to the entire mango tree 10.

  Moreover, in this Embodiment, the spray nozzle 48 for tubes is provided in the flexible tube 24 at substantially equal intervals along the length direction. For this reason, it becomes possible to supply a medicine etc. to mango tree 10 uniformly and certainly. Further, since the tube spray nozzle 48 is rotatable in the circumferential direction of the flexible tube 24, it is possible to spray a medicine or the like on a desired portion of the mango tree 10. Therefore, it is possible to sufficiently supply the drug or the like to a portion hidden from the surface of the mango tree 10 and difficult to reach the drug or the like.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and can be implemented in various modifications.

  Although the above-described embodiment is applied to the mango tree 10, the embodiment can be applied to a tree made of another fruit 18 such as peach or pear or a seedling such as tomato other than the mango tree 10. The method of the present invention may also be adopted when a plurality of mango trees 10 are planted in a large pot or when mango trees 10 are planted directly on the ground without being potted.

  In the above-described embodiment, the head 52 is provided only in one direction in the tube spray nozzle 48 (see FIG. 3). However, the head 52 is not provided in one direction, but in two directions or three directions. It may be provided in multiple directions.

  In the above-described embodiment, the head 52 is fixed to the tube spray nozzle 48. However, as shown in FIG. 4, the head 52 of the tube spray nozzle 48 may be swingable. The tube spray nozzle 48 shown in FIG. 4 includes a head 52 and a support portion 53. The head 52 has a substantially cylindrical shape, and a substantially spherical hollow portion 54 that is recessed toward the inside is provided on the back side of the head 52. The discharge port 50 formed in the vertical direction in FIG. 4 communicates with the hollow portion 54. The discharge port 50 is provided at a substantially circular center when the head 52 is viewed in plan. The hollow portion 54 is provided with a sliding portion 56 that protrudes inward over the circumferential direction 360 °. As shown in FIG. 4, the sliding portion 56 is provided in the hollow portion 54 in a circular arc shape. The sliding part 56 can be formed from elastic bodies, such as rubber | gum, for example. The tip of the support part 53 has a spherical shape. The support portion 53 is provided with a tubular tube portion 55 that communicates with the flexible tube 24. The tube part 55 is opened at the upper end of the support part 53. For this reason, a chemical | medical agent etc. are sent to the pipe part 55, the upper end of the support part 53, and the discharge outlet 50, and are discharged outside.

  The tip of the support portion 53 is accommodated in the hollow portion 54. Specifically, a portion of about 2/3 from the front end side of the support portion 53 is accommodated in the hollow portion 54. That is, the tip side 2/3 of the support portion 53 is covered by the head 52. In this state, a space 57 is formed in the upper region of the discharge port 50 and the hollow portion 54. Further, the inner peripheral surface 56a of the sliding portion 56 and the outer peripheral surface 53a of the support portion 53 are in contact with each other without a gap. For this reason, when the head 52 is tilted, the inner peripheral surface 56 a slides with respect to the outer peripheral surface 53 a of the support portion 53. And the state which the head 52 inclined can be maintained. The head 52 is slidable in the vertical direction (in the direction of arrows AA in FIG. 4) in the circumferential direction 360 ° along the spherical surface of the support portion 53. The head 52 is inclined in the vertical direction as long as the sliding portion 56 does not block the upper end of the tube portion 55. For this reason, even if the head 52 is tilted, the pipe portion 55 always communicates with the space 57. Therefore, even when the head 52 is tilted, the medicine and the like are discharged to the space 57 through the tube portion 55, and the medicine and the like are discharged from the discharge port 50 through the space 57. For this reason, the user can adjust the discharge direction of the medicine or the like by tilting the head 52 of the flexible tube 24 wound around the mango tree 10. Therefore, it is possible to spray a medicine or the like in an arbitrary direction.

  In the above-described modification, the tube spray nozzle 48 is configured by the head 52 and the support portion 53 so as to be able to swing. However, the present invention is not limited to such a configuration. The support portion 53 may be integrally provided, the base portion of the support portion 53 may be formed of a bendable member, and the head 52 may swing around the root portion as a fulcrum. Moreover, the form of the head 52 may not be a columnar shape, but may be a bowl shape or a cap shape that covers the surface of the support portion 53 in a curved shape.

  Further, in the above-described embodiment, the bowl 12 and the flexible tube 24 are provided in a one-to-one correspondence, but are not limited to a one-to-one correspondence. A flexible tube 24 may be provided.

  In the above-described embodiment, each tube spray nozzle 48 has only one discharge port 50. However, the number of discharge ports 50 is not limited to one, and two or more discharge ports 50 are provided. You may do it. For example, the discharge port 50 can be provided in a honeycomb shape like the discharge port of a shower head.

  In the above-described embodiment, the outer jet tube 21 is arranged above the mango tree 10. However, if the outer jet tube 21 is located outside the mango tree 10, the mango tree 10 is arranged. For example, the outer jet tube 21 may be disposed on the side of the mango tree 10. Further, the supply of the medicine or the like from the outside of the mango tree 10 may be performed by a method that does not use the outer jet tube 21. For example, a medicine or the like may be supplied from the outside of the mango tree 10 in a shower form.

  The spraying method of the present invention can be used in the cultivation of trees made of fruits such as mango or seedlings such as tomatoes.
