Description

  The present invention relates to a method for laying agricultural multi-films, especially multi-films used for straw cultivation, and a laying tool.

  In cocoon cultivation, in general, in order to provide the convenience of water level management and harvesting work, a cultivation method is performed in which cocoons having a height of about 30 to 50 cm are made and two seedlings are planted. Further, there is a method of planting 4 seedlings with a cocoon height of about 10 to 20 cm. In any of the methods, a multi-film is laid on the entire surface of the ridge or the passage to keep the ground moist and keep warm, prevent weeds, and prevent actual pollution.

  For crops other than grapes, a film covering the farmland is laid before planting seedlings, so a film with holes of a size suitable for the crops can be used at predetermined intervals. After planting, after growing to some extent, the work of covering the soil surface of the seedling with a film, a film with a hole in advance can not be used, use a black wide film without a hole, I was drilling to match the position of the seedlings. However, it is difficult to specify the location of the seedlings in this work, and the work for providing the holes one by one and pulling the seedlings from the holes is heavy labor. It was done. According to this invention, the perforations are formed by perforating slit holes at predetermined intervals in the multi-film, and the multi-film can be easily formed in the seedlings by tearing the perforation at a position above the seedlings. Can now be laid.

  However, even if the multi-film is laid by the above method, the film is in contact with the upper surface of the irrigation tube that is laid in the longitudinal direction near the center of the strip. However, the water supply pressure fluctuates depending on the location because the irrigation tube is long, and sufficient irrigation cannot be performed, or the pin for preventing meandering is too deep and obstructs the flow of water in the tube. There is a case.

  Also, when the harvesting work is completed and the residue and multi-film of the straw stock are removed, the strain and multi-film are cut between the stock and the multi-film with a sickle for harvesting rice or a shoulder mower, and the residue is taken out of the field. The work was to peel off the multi-film, but the work of pulling out about 2,000 strains per 100 tsubo due to the strong grass force and the hindrance of the stems was a heavy labor, and the multi-film was the rotation of the mower. The removal of the multi-film was a difficult task because it was entangled with the parts and the juice of the cocoon was scattered to the workers. Moreover, in order to carry out the residue from the field, it was necessary to collect the scattered residue in the house, which required a lot of labor. In addition, when disposing of multi-films, if the soil and residues are not separated, they cannot be picked up by the processing company, and the disposal cost is determined by the volume to be picked up. I had to buy a take-off machine.

  Accordingly, an object of the present invention is to provide a multi-film laying method and a laying tool in order to uniformly irrigate the cocoon and dramatically streamline the film removal operation at the end of the cocoon harvesting.

  In the laying work of agricultural multi-film, a space should be provided between the multi-film with slit holes perforated and the ground in the center of the fence, and the multi-film in the central part of the fence should be loosened and installed. The above-mentioned problem is solved by providing an agricultural multi-film laying method characterized by the above.

  By placing the laying tools at equal intervals so as to straddle the irrigation tube provided in the center of the fence and covering the laying tool with a multi-film, a space is provided between the ground in the center of the fence and the multi-film. The above-mentioned problems are solved by providing a method for laying agricultural multi-film, which is characterized by the above.

  Furthermore, the laying tool has a rope holding part for connecting the laying tool to the upper part thereof, and the rope holding part is disposed below the top of the laying tool, thereby providing the laying tool. Solve the problem.

  By laying the multi-film using the agricultural multi-film laying method of the present invention, the slit hole provided in the perforation can be easily torn, so the removal work of the multi-film covered with the reed Becomes easy.

  By using a pin as a laying tool in the agricultural multi-film laying method of the present invention, a space can be provided between the irrigation tube and the multi-film, so that the tube can come into contact with the multi-film during irrigation. And sufficient and uniform irrigation. Furthermore, since the multi-film can be laid and laid, there is less resistance when tearing the multi-film along the slit hole compared to the case of laying the multi-film without loosing, and it can be removed easily. The

  Further, since the irrigation tube can be guided by using a pin as a laying tool, the tube does not meander to obstruct irrigation, and the tube can be arranged without damaging the seedling. And, by connecting these pins at regular intervals, the pins can be arranged at regular intervals on the ridge, and the removal work of the pins becomes easy, and the pins are connected at regular intervals. By keeping it, it can be used continuously in the cultivation of the next year.

  The present invention will be described with reference to the drawings. FIG. 1 shows a cross-sectional view when a multi-film is laid by the multi-film laying method according to the present invention. FIG. 2 shows a state in which a space is provided between the multi-film and the ground using pins as laying tools. FIG. 3 is a view in which the central portion of the multi-film is torn from both end portions along the slit holes provided in the perforated form during the removal operation of the multi-film.

  As shown in FIG. 1, an irrigation tube 2 is arranged between each strip (1 </ b> A, 1 </ b> B) of the seedling 1, and pins 6 are arranged at equal intervals so as to straddle the irrigation tube 2. I will stab you.

  As shown in FIG. 2, the pin 6 as a laying tool has a rope holding portion at the top, and preferably has a rope holding portion below the top. For example, the loop 6A is provided in the upper part, and the rope 6 is inserted into the loop 6A, and the knot 7A is made, so that the pins 6 can be pierced on the ridge 4 at equal intervals. In addition, it is preferable that this pin 6 is provided with a loop 6 </ b> A downward on the top of the U-shaped or U-shaped pin. Of course, other shapes may be used, and a loop may be provided on the top of a single leg pin. It is desirable to have a structure in which these pins can be connected at equal intervals. The pin 6 can be provided so as not to be too deeply inserted into the ground without contacting the irrigation tube 2 so as not to hinder the water passing through the irrigation tube 2. In addition, when using the pin which provided the loop on the upper part of the pin of one leg, it is desirable to provide so that a pin may be staggered and guided so that it may straddle an irrigation tube.

  The interval between the pins 6 is preferably 5 to 6 meters. If the ropes 7 are connected together, the pins 6 can be easily recovered when removed. Furthermore, if knot 7A etc. are made and rope 7 and pin 6 are fixed, it can be used also for cultivation of the next fiscal year and is convenient. The rope 7 and the pin 6 can be fixed by means other than the knot 7A. For example, a member such as a clip can be used. Furthermore, it is not necessary to fix the pin 6 to the rope 7, and it is sufficient that a mark is provided on the rope 7 so that the pin 6 is inserted into the hook 4 at equal intervals.

  Next, it arrange | positions so that the multifilm 3 by which the slit 8 was perforated by the multifilm punching apparatus which is not shown in figure may be covered with the seedling 1. The multi-film perforating apparatus is configured such that the position where the slit hole 8 is perforated is variable according to the number of streaks and the spacing. When the slit hole 8 is drilled using the apparatus, the punching means provided in the apparatus so as to be wider than the width of each strip of the seedling so that the multi-film 3 is loosened and laid. It is better to set the width of.

  Then, since the seedling 1 is directly below, the slit hole 8 provided in the raised portion of the multi-film 3 is torn, the seedling 1 is pulled out from the hole, and the multi-film 3 is laid on the base 4. At that time, by laying the pins 6 so as to cover the multi-film 3, a space 5 is generated between the ground and the multi-film 3, and the multi-film 3 is loosened and laid. By providing the space 5, the irrigation tube 2 does not join the multi-film 3, so that irrigation is not hindered.

  As shown in FIG. 3, in the removal operation, the multi-film 3 is laid at the center of the ridge 4 and has a slack portion 3 </ b> A and is torn along a slit hole 8 provided in a perforated shape. Go. While walking alongside the heel 4, the torn multi-film 3 </ b> A is brought together according to the walking speed and torn to the end of the heel 4. Thereafter, the multi-film 3B remaining on the slopes and passages of the ridge 4 is removed. In addition, since the edge part of the multifilm 3 laid in the adjacent fence is also laid in the passage, it is reasonable to remove it together.

  When the multi-film 3 is laid in a slack state and the space 5 is provided, it is much easier to tear the multi-film 3 along the perforation because there is less resistance than when the multi-film 3 is laid without a slack. This makes the multi-film removal work easier.

  As shown in FIG. 4, a recess 6B can be provided on the top of the pin 6 as a laying tool, and a rope can be inserted and held in the recess. According to this pin, when the end portions are brought close to each other, the opening of the concave portion 6B on the upper side widens, so that the concave portion 6B of the pin can be opened according to the thickness of the rope. Then, compared to the case of the loop shape, inserting the rope into the recess facilitates the work for fixing the rope and the pin, so that the pin can be laid more easily.

  Moreover, since the width | variety of the edge part of the pin 6 can be adjusted by approaching the edge part of the pin 6 mutually, it can change freely in the shape matched with the width | variety of the irrigation tube 2. FIG. Thereby, the irrigation tube can be accurately guided. In addition, about the laying method of the multi film using the said pin, since it is the same as the method mentioned above, it abbreviate | omits.
