Description

  The present invention relates to a pipe strut used together with a fiber net for preventing the fall of a stem when cultivating cut flowers such as small chrysanthemum and carnations and vegetables such as asparagus, and a lodging prevention set including the pipe strut and the net.

  In the cultivation of cut flowers such as Kogiku and carnation, there is a troublesome task of pulling up the fallen fiber nets installed along with the support pipes one by one as the stems of the flowers do not bend. In addition, even in vegetable cultivation such as asparagus, if the stem falls, contact with the storage root will be lost, leading to a decrease in the yield of the next year, so we are taking measures to prevent lodging using props and fiber nets, As with cut flower cultivation, various measures have been taken on how to prevent the fiber net from falling.

  In cut flower cultivation, as shown in FIG. 1, a fiber net (for example, a mesh of 100 to 200 mm square) having a cocoon width of 600 to 1000 mm and a length of 30 to 50 m is conventionally attached to both ends simultaneously with planting a seedling (multi-sheet construction). The pipe struts are cut into a piece of wood, a fiber net is inserted, and the wood frames at both ends are pulled up as the crop grows.

  The pipe struts may be driven vertically, but rather, they are driven diagonally into a reverse eight-letter shape, for example, with a depth of 0.3 to 0.5 m across the crop. In order to prevent the crops from bending the stem in the 100-200 mm mesh of the net, the net is tensioned so as not to loosen.

  The pipe struts have an outer diameter of 15 to 25 mm and an intermediate length of around 1.5 m at a pitch of about 1.5 to 4 m (depending on the land pattern and environment) so that the fiber net does not slide off at both ends. Although struts are generally used, the length of the kite is as long as 30 to 50 m, so that the fiber net often slides down during strong winds and typhoons. If the fiber net slips, the mesh will be deformed and the stem will grow diagonally, reducing the value of the product by half. Vegetables such as asparagus are especially serious because the fall of the stem will have a big impact on next year's harvest.

  At present, as a countermeasure against nets at each production site, a pillar (called wart bamboo) with a projection of about 1 mm on the surface of a colored steel pipe as shown in Fig. 2 is often used. Since it is a protrusion, it is completely lifted by strong winds. Producers tie pipe struts and fiber nets with stopper bands and mica wires (see Fig. 3), and sandwich pipe struts and fiber nets with jigs called packers (see Fig. 4). Ingenuity is given.

  However, the producer has to perform a difficult task of raising the fiber net one by one with respect to a large number of installed columns as the crop grows. At that time, in order to prevent the fiber net from slipping, it is necessary to tie the support and the fiber net together, and the cost of the auxiliary materials such as the stopper band, the packer, and the miker line is enormous.

  Furthermore, after the crop is harvested, it is also necessary to remove the pillars and fiber nets and remove the mica wires and packers tied to the fiber nets. These are also hard work. And next spring, the farmers are plowing the fields with fertilizers and planting seedlings, placing struts, and hanging fiber nets as usual.

  The present invention was devised in view of the current state of the prior art, and its purpose is in a pipe strut for use with a fiber net to prevent stem collapse during cultivation of cut flowers and vegetables as described above. The object is to provide a simple structure that does not impose much labor and high costs on the producer.

  As a result of intensive studies to achieve the above object, the present inventor has determined that the notch portion for hooking the fiber net on the side surface of the pipe strut forming the above-ground portion has a certain height at the cut portion shape of the specific upper end and lower end. It has been found that by providing a pitch, it is possible to easily fix and remove the net while reliably preventing the net from slipping without using a special separate part, and the present invention has been completed.

That is, the present invention has the following configurations (1) to (3).
(1) Pipe struts used with fiber nets to prevent stem collapse when cultivating cut flowers and vegetables. The pipe strut consists of an underground insertion part and a ground part. The notch for hooking the net is provided at a constant height pitch, and the cut portion at the upper end of the notch is formed by being cut obliquely downward when viewed from the front of the notch. A pipe characterized in that the cut portion at the lower end of the portion is formed by cutting in a horizontal direction when viewed from the front of the notch, or formed by being obliquely cut downward when viewed from the front Prop.
(2) The pipe strut has an overall length of 1000 to 2500 mm, an underground insertion portion length of 200 to 500 mm, a width of 10 to 30 mm, and a notch pitch in the height direction of 100 to 400 mm. The pipe support according to (1).
(3) It comprises four or more pipe struts according to (1) or (2), and a fiber net that is hooked on a notch portion of these pipe struts and stretched between the pipe struts. Set to prevent the fall of cut flowers and vegetable stems.

  The pipe strut of the present invention is simply provided with notches at a constant height pitch in the ground part of the pipe strut as a hooking part for fixing the fiber net. The net can be easily fixed and removed by the structure. Moreover, since the pipe support | pillar of this invention makes the cutting part of the upper end and lower end of a notch part for hooking a fiber net into a specific shape, it moves to the notch part above a fiber net, and below a fiber net. Prevention of sliding down is easily achieved.

FIG. 1 is a photograph showing a conventional method for preventing the fall of stems during cut flower cultivation. FIG. 2 is a photograph showing an example in which a conventional pipe column called a wart bamboo is used. FIG. 3 is a photograph showing an example in which a pipe strut and a net are bundled using a conventional miker line. FIG. 4 is a photograph showing an example in which a pipe support and a net are sandwiched using a conventional packer. FIG. 5: shows the schematic of the pipe support | pillar of this invention, (a) is the figure which looked at the notch part from the front, (b) is the figure which looked at the notch part from the side. FIG. 6 is a photograph showing a state in which the pipe support of the present invention is inserted into the ground and a fiber net is hooked on the notch. FIG. 7 is another photograph showing a state in which the pipe support of the present invention is inserted into the ground and a fiber net is hooked on the notch.

  The pipe strut of the present invention is used to fix a fiber net that is supported to prevent the stem from falling or bending when growing cut flowers such as small chrysanthemums and carnations and vegetables such as asparagus.

  A typical example of the pipe strut of the present invention is shown in FIG. As can be seen from FIG. 5, the pipe strut 1 of the present invention includes an underground insertion portion 2 that is inserted into the ground to stabilize the pipe strut, and a ground portion 3 that is engaged with the fiber net on the ground. . The overall length of the pipe support 1 is preferably 1000 to 2500 mm, the length of the underground insertion portion 2 is preferably 200 to 500 mm, and the width is preferably 10 to 30 mm. What is necessary is just to change suitably the whole length of the pipe support | pillar 1, and the length of the above-ground part 3 with the growth height of the crop to grow.

  In the pipe strut 1 of the present invention, the notches 4 for hooking the net on the side of the pipe strut of the ground portion 3 are provided at a constant height pitch, and the notches 4 have a specific shape. Is a feature. As shown in FIG. 5, the cutout portion 4 is composed of a cut portion 5 at the upper end and a cut portion 6 at the lower end, and the cut portion 5 at the upper end is obliquely downward when viewed from the front of the cutout portion 4. The cut portion 6 at the lower end is formed by cutting in the horizontal direction when viewed from the front of the cutout portion 4 or formed by being cut obliquely downward when viewed from the front. Has been. Here, the oblique direction is not necessarily a straight line, and may be bent. About 5 to 15 notches 4 are preferably provided at a pitch of 100 to 400 mm in the height direction from a position 250 to 450 mm from the tip of the underground insertion portion 2 of the pipe column 1. Moreover, although the depth of the cut of the notch part 4 is based also on the width | variety of a pipe support | pillar, about 5-12 mm is common.

  The reason why the cut portion 5 at the upper end of the cutout portion 4 is formed as described above is to make it easy to raise the net to the cutout portion 4 at the upper height. The reason is that the net is reliably prevented from sliding down while facilitating the hooking of the net.

  As the pipe strut of the present invention, a conventionally known metal or wooden one can be appropriately employed, but in consideration of corrosion resistance and durability, the surface of the metal pipe is thickly galvanized. It is preferable to use a thing or a thing which gave baking painting thickly. The pipe struts of the present invention are not only those having a circular cross section but also those having a C-shaped cross section.

  In the present invention, four or more, preferably several dozen or more, pipe struts are prepared, and a fiber net is provided to be hooked between the pipe struts and stretched between the pipe struts. And a vegetable stem preventive set. As the fiber net, those conventionally used for preventing the fall of the stem can be used as they are, and for example, it is preferable to use a synthetic fiber net having a mesh of 50 to 250 mm square, preferably 100 to 200 mm square. .

  The pipe struts and lodging prevention set of the present invention greatly reduce the labor involved in preventing the fall of cut flowers and vegetable stems, and the structure is simple and inexpensive, so cut flowers and vegetables It is extremely useful for producers.
