Abstract

<P>PROBLEM TO BE SOLVED: To provide a device capable of being easily applied from the early phase of plant growth without damaging stems, and for preventing farm products from vermin such as an armyworm without damaging growth, which vermin moves from the ground along the stem and eats leaves away. <P>SOLUTION: The device is formed of an elastic soft material, has a structure formed with a cut (3) directing from the periphery to the center, having length overcoming the center and not reaching at the opposite side edge, can be easily attached from the early phase of plant growth without injuring stems by inserting to the center part a farm product stem near the ground surface from the cut (3) to be near the center part, and closing the beginning of the cut (3), and prevents farm product damages caused by a vermin such as the armyworm from the ground, without damaging stem growth. And a structure having a center part (1) formed of an elastic soft material and a peripheral part (2) formed of a foldable, lowly retractile and hard material decreases distortion of the elastic soft material, caused by stem growth of farm products. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、ヨトウムシなどの土中に潜む害虫からキャベツや白菜などの農作物を防護する用具に関するものである。 The present invention relates to a tool for protecting crops such as cabbage and Chinese cabbage from pests lurking in soil such as weevil.

ヨトウムシは夜に土中からキャベツや白菜などの農作物の茎を伝って葉を食い荒らす代表的な害虫である。 Caterpillars are a typical pest that eats and eats leaves from the soil through the stalks of cabbage, Chinese cabbage and other crops at night.

ヨトウムシなどの土中に潜む害虫から農作物を守る手段としては、農薬散布や夜の活動時に取除くことや茎周辺の土中を掘り返して取除くなどがあるが、農薬を使いたくない場合や一匹ずつ探し出す手間などの問題を抱えている。 There are several ways to protect crops from pests such as weevil, such as spraying pesticides, removing them during night activities, or digging the soil around the stems. It has problems such as the trouble of finding each animal.

また、特許公開平０８−２３８６４では用具の取り付け穴の内径が樹木の直径より大きくした構造であるため、あらかじめ開けられている穴に農作物の成長初期の茎を隙間無く密着させる構造とはなっていない。また、害虫の移動阻止用具と樹木保護材とは同一構造体ではないので設置には樹木保護材を巻いてから害虫の移動阻止用具を取り付けるため設置が容易ではない。そして、キャベツや白菜などでは、苗から収穫期までに茎が１０倍近くも太くなる農作物においては利用し難い。さらに、樹木取り巻き部材と薬剤収容部部材とカバー部材とによる立体構造においては切れ目を容易に十分開くことは困難である。 Further, in Japanese Patent Application Laid-Open No. 08-23864, since the inner diameter of the attachment hole of the tool is larger than the diameter of the tree, the structure is such that the stalk in the early growth stage of the crop is in close contact with the hole that has been opened beforehand. Absent. In addition, since the pest movement prevention tool and the tree protection material are not the same structure, the installation is not easy because the pest movement prevention tool is attached after the tree protection material is wrapped. And cabbage, Chinese cabbage, etc., are difficult to use in crops whose stems are almost 10 times thicker from seedling to harvest. Furthermore, it is difficult to easily open the cut sufficiently in the three-dimensional structure including the tree winding member, the medicine container member, and the cover member.

キャベツや白菜などを無農薬または低農薬で栽培する場合、飛んでくる害虫は防虫シートなどによるトンネル敷設で防護できるが、ヨトウムシなど土中から出てくる害虫を農薬を用いずに効果的に防護するのは困難であり被害が少なくない。 When growing cabbage, Chinese cabbage, etc. with pesticide-free or low pesticides, flying pests can be protected by tunnel laying with insect repellent sheets, but pests such as weevil are effectively protected without using pesticides. It is difficult to do and damage is not a little.

そこで、本発明は、キャベツや白菜などのように成長初期から収穫期までに茎が１０倍近くも太くなる農作物においても成長初期から容易に装着でき、収穫期まで装着し続ける間の農作物の成長を阻害することなく、ヨトウムシなどの土中からの害虫から農作物の被害を回避できる軽量かつ装着が容易な用具の提供を課題とした。 Therefore, the present invention can be easily attached from the initial growth stage to crops such as cabbage and Chinese cabbage that grow about 10 times thicker from the initial growth stage to the harvesting period. It was an object to provide a light-weight and easy-to-wear tool that can avoid damage to crops from pests from the ground such as weevil without hindering the damage.

本発明は、中心部（１）がウレタンフォームなどの弾力性のある柔らかく軽量な素材で、装着する農作物の収穫期の茎の直径よりも十分大きく形成し、辺縁部（２）はポリエチレンや厚紙などの折り曲げができる伸縮性が低く硬い軽量な素材で形成し、外側縁より中心に向かい中心を越える長さでありかつ中心部（１）の反対側の縁まで達しない長さの切れ目（３）の入った構造とした。 In the present invention, the central part (1) is made of a flexible and lightweight material such as urethane foam, and is formed to be sufficiently larger than the diameter of the stalk at the harvesting time of the crop to be attached. It is made of a hard, lightweight material that can be folded, such as cardboard, and has a length that extends from the outer edge toward the center and beyond the center and does not reach the edge opposite to the center (1) ( It was set as the structure containing 3).

弾力性のある柔らかい素材で形成し、外側縁より中心に向かい中心を越えない長さの切れ目では、茎の成長により本発明の構造体は切れ目（３）の延長上の延長方向にずれてしまうが、外側縁より中心に向かい中心を越える長さでありかつ反対側の縁まで達しない長さの切れ目（３）を形成することにより、茎の成長によっても本発明の構造体にずれが生じなくなった。 In the case of a cut line that is formed of an elastic soft material and has a length that extends from the outer edge toward the center and does not exceed the center, the structure of the present invention shifts in the extending direction on the extension of the cut line (3) due to the growth of the stem. However, by forming a cut (3) having a length that extends from the outer edge toward the center and exceeds the center and does not reach the opposite edge, the structure of the present invention is also displaced by the growth of the stem. lost.

また、中心部（１）は弾力性のある柔らかい素材で形成し、辺縁部（２）は折り曲げができて伸縮性が低く硬い素材で形成した構造により、農作物の茎の成長によって生じる弾力性のある柔らかい素材の歪みを軽減できた。 In addition, the central part (1) is made of an elastic soft material, and the edge part (2) is made of a hard material that can be bent and has low elasticity. We were able to reduce distortion of soft material with.

ウレタンフォームなどの弾力性のある柔らかく軽量な素材で装着する農作物の収穫期の茎の直径よりも十分大きく形成した中心部（１）により、本発明を装着したキャベツや白菜などの茎の直径は収穫期までに成長を阻害されることなく成長初期の１０倍近くになったが、茎は中心部（１）に隙間無く収まっていた。 The diameter of the stems of cabbage, Chinese cabbage, etc. equipped with the present invention is due to the central part (1) formed sufficiently larger than the diameter of the harvesting stems of the crops to be mounted with a flexible, soft and lightweight material such as urethane foam. The growth was nearly 10 times that of the initial growth without being hindered by the harvesting period, but the stems were stored in the center (1) without any gaps.

本発明の構造により、本発明を装着したキャベツや白菜は成長初期から収穫期までにヨトウムシなどの土中から茎（４）を伝わってくる害虫による被害がほとんど無くなった。 According to the structure of the present invention, cabbage and Chinese cabbage equipped with the present invention are almost free from damage caused by insect pests transmitted from the soil such as weevil to the stem (4) from the early growth stage to the harvesting period.

図１と図２とで示す形態を最良の形態とする。すなわち、中心部（１）はウレタンフォームなどの弾力性のある柔らかく軽量な素材で、装着する農作物の収穫期の茎の直径よりも十分大きく形成し、辺縁部（２）はポリエチレンや厚紙などの折り曲げができて伸縮性
低く硬い軽量な素材で形成し、外側縁より中心に向かい中心を越える長さでありかつ中心部（１）の切れ目（３）の反対側の縁まで達しない長さの切れ目（３）の入った構造とした。The form shown in FIGS. 1 and 2 is the best form. That is, the central part (1) is made of a flexible, soft and lightweight material such as urethane foam and is formed to be sufficiently larger than the diameter of the stalks of the crops to be mounted, and the marginal part (2) is made of polyethylene or cardboard. It is made of a lightweight material that can be bent, stretched and hard, and has a length that extends from the outer edge toward the center and beyond the center, and does not reach the opposite edge of the center (1) cut (3) It was set as the structure where the cut | interruption (3) entered.

切れ目（３）は、閉じた状態では辺縁部（２）には隙間があるが中心部（１）には隙間はない。 In the closed state (3), the edge (2) has a gap in the closed state, but the center (1) has no gap.

本発明を茎（４）に装着するには、切れ目（３）を両手で開きながらキャベツや白菜などの成長初期の茎（４）の地面に近い部分に切れ目（３）を差し入れて、中心部（１）の中央付近に茎（４）が来たところで開いた切れ目（３）を閉じ、辺縁部（２）の切れ目（３）を粘着テープやホチキスなどで固定して切れ目が開かないようにする。 To attach the present invention to the stem (4), open the cut (3) with both hands and insert the cut (3) into the portion of the early growth stem (4) such as cabbage or Chinese cabbage close to the ground. Close the cut (3) when the stem (4) comes near the center of (1), and fix the cut (3) at the edge (2) with adhesive tape or staples so that the cut does not open To.

図３は、図１と図２に示す最良の形態を茎（４）に装着した例である。 FIG. 3 shows an example in which the best mode shown in FIGS. 1 and 2 is attached to the stem (4).

農作物の栽培管理において、土中から出てくる害虫の防護に有用である。 It is useful for the protection of pests emerging from the soil in the cultivation management of agricultural crops.
