Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a multi-film holding pile for preventing the multi-film that completely covers the ridges and furrows from lifting up.

BACKGROUND ART In recent years, full-scale mulch cultivation, in which the ridges and furrows are completely covered with a mulch film, has become widespread when cultivating vegetables and the like. In such fully mulched cultivation, soil is generally placed intermittently on top of the mulch film that covers the furrows in order to prevent the mulch film from lifting due to wind, etc. The work is very hard work.

Therefore, as described in Japanese Utility Model Publication No. 63-29395, a substantially T-shaped multi-film holding pile consisting of a holding plate and a pile body is used, and the multi-film holding pile is inserted from above the multi-film covering the ridges. Multi-film is prevented from floating by sticking it into the field.

Problems that the invention aims to solve Although ridges for growing vegetables and the like are generally formed along contour lines, ridges and furrows still often have some slope. here,
If soil is intermittently placed on top of the mulch film that covers the ridges to prevent the mulch film from lifting up, this soil will act as a dam for the flow of rainwater and sprayed chemical solutions, causing damage to the vegetables, etc. being cultivated. Enough water and chemical solutions can be supplied.

On the other hand, the multi-film holding pile as described in Japanese Utility Model Publication No. 63-29395 does not have the effect of damming rainwater etc. flowing along diagonal lines on the multi-film covering the ridges. For this reason, the supply of water and chemical solutions to cultivated vegetables, etc. is insufficient, and the quality and yield of vegetables, etc. are reduced.

Means for Solving the Problem A stake body is provided on the upper end of the piercing portion that penetrates the multi-film that completely covers the ridges and furrows and penetrates into the field, to which a holding plate for holding down the multi-film is fixed, and the holding plate is A substantially trapezoidal protrusion that conforms to the cross-sectional shape of the ridge is provided on the upper surface.

Function: When the piercing part of the pile body is inserted into the field through the mulch film covering the furrows, the mulch film is held down by the holding plate and prevented from lifting up. In addition, by keeping the protrusion facing perpendicular to the ridge when inserting it into the field,
Rainwater, chemical solutions, etc. flowing along the slope on the multi-film covering the ridges are dammed by the protrusions.

Embodiment An embodiment of the present invention will be described based on the drawings.
First, a substantially T-shaped plastic pile main body 3 is provided, which is composed of a piercing part 1 having a wedge-shaped tip and a presser plate 2 integrally formed at the upper end of the piercing part 1. Wave-shaped unevenness 4 is formed on the side surface of the piercing portion 1, and the pressing plate 2
A protrusion 5 that protrudes downward is formed in a straight line on the lower surface of the holder.

Next, a substantially trapezoidal plate-shaped protrusion 7 having a cross-sectional shape of the ridges 6 is integrally formed on the upper surface of the presser plate 2 .

In such a configuration, the ridges 8 and the ridges 6 are completely covered with the multi-film 9, and the piercing part 1 of the pile body 3 is penetrated through the multi-film 9 covering the ridges 6 and pierced into the field. As a result, the holding plate 2 presses the multi-film 9 against the field, and the pile bodies 3 are installed intermittently at regular intervals, thereby preventing the multi-film 9 from lifting up. In addition, a protrusion 5 formed on the lower surface of the presser plate 2
This causes the multi-film 9 to dig into the field, helping to prevent the multi-film 9 from lifting up. Furthermore, since the wave-shaped unevenness 4 is formed on the side surface of the piercing portion 1, the pile body 3 is difficult to come off, and the multi-film 9 is further prevented from floating.

Next, by orienting the protrusion 7 in a direction perpendicular to the ridges 6 when stabbing the stabbing part 1 into the field, the third
As shown in the figure, the protrusion 7 is in a state of blocking the bottom of the ridge 6. Therefore, even if the ridges 8 and the ridges and grooves 6 are inclined, the rainwater and sprayed chemical solution flowing on the multi-film 9 that covers the ridges and grooves 6 are blocked by the protrusions 7 as shown in Fig. 4. It will be done. Projection 7
The rainwater and chemical solutions dammed up by the dam permeate into the field through the holes formed in the multi-film 9 when the piercing part 1 is pierced, and the holes 10 formed in advance in the multi-film 9 covering the ridges 6. , water and chemical solutions are sufficiently supplied to the crops 11 planted in the rows 8.

Effects of the invention As mentioned above, the present invention has a substantially trapezoidal protrusion that follows the cross-sectional shape of the ridges on the upper surface of the retaining plate of the pile body, which prevents the multi-film that completely covers the ridges and ridges from lifting up. With this provision, the bottom of the furrow can be blocked by the protrusion by piercing the mulch film covering the furrow with the piercing part of the pile main body and sticking it into the field. The protrusions can dam up rainwater and chemical solutions that flow along the slope on the film, and therefore prevent rainwater and chemical solutions from penetrating into the field through holes pre-formed in the multi-film and overlapping parts of the multi-film. This has the effect of making it possible to sufficiently supply water and chemical solutions to crops.
