(1) IX. Description of the invention [Technical field to which the invention pertains] " The present invention relates to a strut, particularly to an agricultural pole, - for use in the cultivation of vines, such as tomatoes, grapes, Fruit and vegetable crops such as green beans. [Prior Art] Φ In the cultivation of vines, a part of bamboo, metal or wood rods is generally inserted into the soil, allowing the vines to naturally climb up the rod. However, the surfaces of these rods are smooth and do not allow the growth of the long-leaf stalks to climb upwards (as shown in the first image). Moreover, these rods are easily corroded and destroyed under the long-term sun and rain. Furthermore, when there is a strong wind, the structure of the part buried under the soil (as shown in the first figure), and the stalk that climbs on the rod are subjected to the oncoming wind, the rod The part buried under the soil will not be able to withstand the Φ stress component of the wind in the horizontal direction, so the rod will collapse quickly. The shortcomings of the above-mentioned conventional rods often cause losses on crops, which affect the income of farmers. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an agricultural struts which have low manufacturing cost, high flexural strength, and are steadily erected in soil and are not easily corroded. The agricultural struts according to the present invention include: one rod The body 'includes a rod portion -4 - (2) 1312271 and a plurality of ribs extending along the length of the rod body on the outer surface of the rod portion; and a pile body having at least one pair symmetrical to the rod The axial wing of the body. The ribs on the body enhance the bending strength of the shaft to withstand the stress of the wind relative to the shaft. The pair of mutually perpendicular wings on the pile provide horizontal resistance in the soil to allow the agricultural struts to stand firmly in the soil. Preferably, the ribs have a plurality of outwardly extending projections to allow the stalks of the long φ to adhere thereto and climb upward. Preferably, the cross section of the rod portion of the rod body is circular or equilateral polygon so that the rod body has the same bending strength in different horizontal directions. Preferably, each of the at least one pair of wings of the pile has a sharp edge around it so that the pile can be easily inserted and pulled out of the soil. Preferably, the agricultural struts further comprise an elongated rod body attached to the shank of the struts. Preferably, the agricultural pole is integrally formed of a plastic material. [Embodiment] - The agricultural struts of the present invention will be described in detail in the following embodiments in conjunction with the drawings. However, the invention is not limited to such embodiments. As shown in the second and third figures, the agricultural struts according to an embodiment of the present invention comprise a rod 1 and a pile 2. As shown in the third figure, the rod body 1 includes an elongated cylindrical rod portion 1 1 and four ribs extending along the longitudinal direction of the rod body 1 on the outer surface of the rod portion 11 and spaced apart from each other by a 90 degree angle. Department 12. The upper end of the rod portion 11 has an engaging hole 111, and -5-(3) 1312271 is used to accommodate the engaging portion 3 3 of the other elongated rod body 3 (as opposed to two of the four ribs 12 in the fourth figure) The ribs I2 are formed with a plurality of protruding protrusions 1 2 1 for allowing the leaf stalks of the plants to climb up the protrusions 1 2 1 to grow upwards (as shown in the second figure). As shown in the third figure, The pile body 2 includes a pair of wing members at its lower end, and the wing members 22 are perpendicularly disposed with respect to the central axis of the pile body 2 with sharp edges 221 around them to facilitate easy insertion and extraction of the pile body 2. The shape of the member 22 is an elongated hexagon in the present embodiment. The present invention is not limited to this shape. The agricultural struts are integrally molded by a plastic material or by adding a chemical component such as a fiber. When the pole is poled, the pile body 2 is perpendicular to the soil, and the seedlings can be planted around the pole as shown in the second figure, so that the growing leaf stems are attached to the ribs of the shaft 1 121, and then climbed up around the shaft 1. The fourth figure is an exploded view of the agricultural struts shown in the third figure, and the fifth The agricultural pole diagram shown in the fourth figure, and the sixth diagram shows a sectional view of the section line 6-6 in the fifth diagram of the shaft of the agricultural pole of the present invention. It is shown that when it is necessary to increase the length of the rod body 1, one or several elongated rod bodies 3 are attached to the upper end of the rod body 1, and the elongated shaft has substantially the same structure as the rod body 1. The rod body 3 includes an elongated cylinder 31. And four ribs 32 extending along the longitudinal direction of the rod 3 on the rod portion 31 and spaced apart from each other by an angle of 90 degrees. The upper end of the rod portion 31 has an indication). Wrap around the extension 22 . The ground is placed out of the soil, but the other strong inserts or the protruding rods on the plant are viewed along the first time. The outer surface of the body 3 is engaged with the hole -6-(4) 1312271 311. To accommodate the joint portion 33 of the other elongated rod body 3. The two opposite ribs 32 of the four ribs 32 are formed with a plurality of outwardly extending protrusions 321 ' for allowing the leaf stalk of the plant to climb over the protrusion 321 and continue to grow upward around the rod 3 As shown in the seventh embodiment, according to another embodiment, the rod portion 11 of the rod body 1 and the rod portion 31 of the elongated rod body 3 have a square shape in a cross section, wherein the rod portions 11, 31 also include a plurality of The ribs 12, 32 of the protrusions 121, 321 . Instead of φ, the shape of the rod portion 1 1 of the rod body 1 and the rod portion 31 of the elongated rod body 3 in the cross section may be an equilateral polygon. Although the above embodiments have explained in detail the structure, features and functions of the present invention. Modifications and alterations of the structure may be made by those skilled in the art after reading the above description. However, such modifications and variations are still within the scope of the invention. [Simple description of the diagram] The first figure shows a schematic diagram of climbing of vines in which the conventional rods are fixed in the soil. The second figure shows a schematic diagram of the climbing of the climbing vines in which the agricultural struts of the present invention are fixed in the soil. Figure 3 is a perspective view of an agricultural struts according to an embodiment of the present invention. The fourth figure is an exploded view of the agricultural struts shown in the third figure attached to an elongated rod. The fifth figure is a top view of the agricultural pole shown in the fourth figure. (5) 1312271 Fig. 6 is a cross-sectional view showing the rod body of the agricultural struts of the present invention taken along the section line 6-6 in the fifth figure.
