Description

  The present invention relates to a broken stem repair clip for holding, reinforcing, and activating stems and vines when they are broken or torn at the time of attracting vine fruit vegetables such as tomatoes, cucumbers and melons.

  Vine fruit vegetables such as tomatoes, cucumbers, and melons cannot stand by their own weight when the stems grow. Therefore, in vinyl house (facility horticulture) cultivation, as shown in FIG. 8, an attracting string 31 for hanging a stem is attached to an attracting line 30 stretched horizontally on the ceiling of the vinyl house, and details are shown in FIG. As shown in Fig. 2, the suspended attracting cord 31 is sandwiched by the attracting cord pinching portion 41 near the fulcrum portion of the citation clip 40, and at the same time, a stem 50 such as tomato is put in the stem holding portion 42, and the stem is suspended upright. An attraction method has been implemented.

  As another method, as shown in FIG. 10, support columns 60 are set up at regular intervals on the ridges in the vinyl house, and several stages are attached in the lateral direction while winding the attracting cord 61 around the support columns 60, as shown in detail in FIG. In addition, the attracting cord 61 stretched in the lateral direction is sandwiched by the attracting cord pinching portion 41 near the fulcrum portion of the citation clip 40 and at the same time the stem 50 such as tomato is sandwiched in the stem holding portion 42 and the stem 50 is lifted diagonally. The horizontal string attraction method is widely used in gardening.

  Tomato horticulture has many long-term cultivation, and since it grows for almost a year, the position where the stem is fastened is moved according to the growth of the stem, and it is produced and harvested while the stem is fastened with a quotation clip. .

  As shown in FIGS. 8 and 10, the tomatoes have fruit bunches 51, 52, 53 in order from the part close to the base of the stem 50 (lower part) to the middle part and the upper part, so that the fruit in the lower part close to the base of the stem is obtained. Harvesting is started in sequence from the tuft 51, and the portion of the stem 50 after harvesting is shifted downward as shown in FIGS. The tip 55 of the growing part of the stem 50 continues to grow upward, and the fruit tress 54 also grows from the stretched stem part. To go.

  At the time of the operation of lowering the stem 50, work is performed over a long period of time so as not to break or twist the bent portion of the stem 50, but this is heavy labor, and an operator who is not accustomed to the attraction work May twist and tear.

  In tomato horticulture, long-term cultivation (long-running) is often carried out, planting around August, starting harvesting from October, and harvesting until June of the following year to harvest about 20 stages of fruit bunches from one stem. At the time of attracting work, if the part that bends the stem breaks, the growing part of the stem will stop growing or die from the broken part of the stem, making it impossible to harvest.

  When the tomato stem is attracted, for example, as shown in FIGS. 14 and 15, if the stem is broken at the lower part of the fourth-stage fruit bunch 54, if the stem is left as it is, the upper part will wither from the broken part 56. End up. Therefore, in the case of long-term cultivation, fruit bunches can be harvested for about 20 stages, but only the third stage fruit bunches 53 can be harvested.

  Also, as shown in FIGS. 16 and 17, when the stem 50 is twisted and torn, a part of the conduit or the like passing through the inside of the stem 50 is damaged, and the growth of the upper part from the torn portion 58 is delayed. Sometimes.

  For this reason, in the case of the majority of tomato producers, the skilled person repairs the broken portion 56 or the torn portion 58.

  One of the repair methods is a commercially available vinyl as shown in FIG. 19 with the broken portion 56 of the tomato stem 50 as shown in FIGS. The tape 70 is wound around and fixed to the stem 50 before and after the broken portion 56, and the broken portion 56 is repaired. However, in this repair method, the vinyl tape 70 has to be wound several times, and at this time, extreme care must be taken so that the leaves and fruits around the broken portion 56 of the stem are not caught in the vinyl tape 70. It takes time and effort to repair one place.

  Further, in order to repair and fix the broken stem portion 56 and the torn portion 58 so as not to bend or shift, the vinyl tape 70 is overlapped with the chopsticks and the bar-like splint 71 as shown in FIG. In some cases, it can be repaired by getting involved, and it takes a lot of work.

  As another repair method, as shown in FIG. 21, there is a method of using a commercially available strut citation clip 80 that sandwiches a strut at the tip of the clip 80 and attracts a stem. As shown in FIG. 22, the clip 80 originally has a stalk 50 attached to a support 60 standing on a heel, and the stalk 50 is sandwiched between stalk holders 81 of the clip 80, followed by a support squeezing part at the tip of the clip 80. This is an invitation clip that sandwiches the support 60 at 82. The stem holding portion 81 and the support pinching portion 82 can be opened and closed by picking the knob 83 and are pressed by the C-shaped spring 84 so as to hold the closed state.

  Some producers may use the clip 80 as a substitute and repair the broken portion 56 or the torn portion 58 with the support pinching portion 82 as shown in FIG. However, in this supporting column invitation clip 80, the diameter of the supporting pin sandwich portion 82 is about 16 mm, the thickness of the tomato stem 50 is less than 16 mm in diameter, and the growing stem 50 portion has a diameter of around 12 mm. Since there are many, the majority of stems cannot be pinched, and the pinching force is also weak, so it is unsuitable as a repair clip for the broken portion 56 or the torn portion 58, and the cut surface of the broken stem is not well worn. .

  In addition, in plants such as tomato, eggplant, and cucumber, plant reinforcements attached to stems to prevent stem breakage are proposed in Patent Documents 1 and 2, but for the purpose of repairing broken stems and torn stems. Not suitable for use.
