る。[Detailed Description of the Invention] Industrial field of application The present invention relates to a fertilizing needle for a multi-film, and when fertilizing the soil surface on which the multi-film is laid, insert a needle blade from the upper surface of the multi-film into the soil surface. Then, this needle body is related to a fertilizer application needle for injecting fertilizer from the injection hole.
従来の技術、および考案が解決しようとする問題点 マルチフイルムで被覆された土壌面に対する施肥におい
て、施肥針を用いる場合、この施肥針の針身先端部に形

針から噴入する肥料に方向性を持たせて、できるだけ広
域に亘って施肥させるものである。Problems to be solved by the conventional technology and the invention When fertilizing a fertilizer on a soil surface coated with multi-film, when a fertilizer needle is used, the fertilizer is applied depending on the direction of the nozzle hole formed at the tip of the needle body of the fertilizer needle. However, the fertilizer ejected from the injection hole is immediately diffused to the surroundings, and the directionality to the long distance is small. In this invention, the fertilizer injected from the fertilizer application needle is directed so that the fertilizer is applied over a wide area as much as possible.

マルチフィルム用の施肥針の構成とする。Means for Solving the Problems This invention has a mulch film 2 having a nozzle hole 1 at the tip.
The pressing board 7 is provided below the needle 4 which pierces the soil surface 3 into the soil surface 3 and injects the fertilizer. The pressing board 7 has a lower surface and a contact surface portion 6 in contact with the upper surface of the mulch film 2 and above. Non-contact surface portion 5 located at the position not contacting the mulch film 2
The fertilizer needle for mulch film is characterized in that and are provided along the radial direction.
考案の作用、および効果 施肥しようとする個所のマルチフィルム２上面から土壌
面３に向けて施肥針を刺込むと、この針身４に一体の押
え盤７の接触面部６の下面がマルチフィルム２の上面に
押当てられて、隣接する非接触面部５ではマルチフィル
ム２面に対する押圧力が無いか、又軽く押えるが、接触
面部６ではマルチフィルム２を土壌面３に対して強く押
圧する。When the fertilizer application needle is inserted from the upper surface of the mulch film 2 at the portion to be fertilized toward the soil surface 3, the lower surface of the contact surface portion 6 of the presser board 7 integrated with the needle body 4 becomes mulch film 2 The adjacent non-contact surface portion 5 is pressed against the upper surface of No. 2 or has no pressing force against the surface of the mulch film 2 or can be lightly pressed, but the contact surface portion 6 strongly presses the mulch film 2 against the soil surface 3.
このため、針身４内から噴孔１を経て土壌中へ噴込まれ
る肥料は、この押え盤７により押圧力の小さい非接触面
部５の空間部に沿って噴流されて、放射方向へ集中的に
流れ、この結果、噴吹拡散される施肥領域を広くするこ
とができる。Therefore, the fertilizer injected from the inside of the needle body 4 into the soil through the injection hole 1 is jetted by the holding plate 7 along the space of the non-contact surface portion 5 with a small pressing force, and is concentrated in the radial direction. As a result, it is possible to widen the fertilization area to be sprayed and diffused.

沿って交互に設けられている。Example In the illustrated example, the fertilizer application needle is made of a pipe, and a passage hole (8) for passing fertilizer is provided along the center of the needle body (4), the tip is formed in a pyramidal shape, and a position above the tip is provided. In, the injection hole (1) is arranged on the outer circumference. The presser plate (7) is made of a circular sheet metal, rubber or the like, and the lower surface is recessed into a conical shape, and the needle body (4) is inserted into the central portion of the presser plate (7).
The tip portion of the is set to an appropriate length and is projected below the holding plate (7). On the lower surface of the presser board 7, contact surface portions 6 contacting the upper surface of the mulch film 2 and non-contact surface portions 5 positioned above the mulch film 2 that do not contact the mulch film 2 are provided alternately along the radial direction. .
