Description

本発明は、農作物を栽培する畝やビニールトンネルに被せるシート、果樹の下に敷くシートなどの農業用被覆シートに関するものである。 TECHNICAL FIELD The present invention relates to agricultural covering sheets such as sheets for covering ridges and vinyl tunnels for cultivating crops, and sheets for laying under fruit trees.

農業用被覆シートには、保温や雑草防止を目的とした黒い不透明のマルチシート、ビニールトンネルに被せる透明シートや不織布シート、果樹の下に敷く反射シートなどがある。
Covering sheets for agriculture include opaque black mulch sheets for heat retention and weed control, transparent sheets and non-woven fabric sheets for covering vinyl tunnels, and reflective sheets for laying under fruit trees.

実開昭５２－０５９４３Japanese Utility Model Laid-Open Showa 52-05943 特許３８６２７２７Patent 3862727

畑に畝を作り農作物を栽培する場合、保温ないし雑草防止を目的として、マルチシートと呼ばれる黒い農業用のシートを畝の表面に被せることがある。 一般的には、長方形の黒いシートを畝に沿って被せ、このシートの両端部の上から土を盛り付け畝に固定していた。
また、保温ないし促成栽培を目的として、透明または半透明のシートを半円形の支柱に被せてビニールトンネルを作り、このシートの両端部の上から土を盛り付け畝に固定していた。
しかし、このシートの固定方法は土の盛り付け作業に手間が掛り、土を十分に盛り付けていないと風により捲れ上がって外れることがあり、シートを安全かつ確実に固定し難かった。 When ridges are made in a field to cultivate crops, the surface of the ridges is sometimes covered with a black agricultural sheet called a mulch sheet for the purpose of heat retention or weed control. In general, a rectangular black sheet was placed along the ridges, and soil was piled up on both ends of the sheet and fixed to the ridges.
In addition, for the purpose of heat retention or forcing cultivation, a transparent or semi-transparent sheet was covered on a semicircular support to make a vinyl tunnel, and soil was piled up from both ends of this sheet and fixed to the ridge.
However, in this method of fixing the sheet, it takes time and effort to pile up the soil, and if the soil is not piled up sufficiently, it may be blown up by the wind and come off, making it difficult to fix the sheet safely and reliably.

この解決策として、特許文献１ではシートの両端部のシートを折り返して一定間隔で接合して接縁部に沿ってポケットを形成し、このポケットに土砂などを詰めてその重みでシートを地面に固定している。
特許文献２ではシートの両端部のシートを折り返して、その内側を一定間隔で交互に接合してポケットを形成し、このポケットに土壌などを詰めてその重みでシートを地面に固定している。
前記のいずれの方法においても、シートの両端部にポケットを形成し、シートの取付け前にポケットに土壌を詰めているので、ポケット内に十分な重りとなる量の土壌を詰めるのは単純にシートの上に土を盛付けるよりも手間が掛るし、シートを回収する前には一度詰めたポケット内の土壌をポケットから取り出さなければならず、回収にも相当手間が掛るし雨天後には泥塗れになるので、これを避けるには雨天後に日数を経ないと直ぐには回収できないなどの不具合がある。

本発明は上記に鑑みて、シートの取付け作業が極めて簡単で回収も容易な、安全かつ確実に固定できる農業用被覆シートを提供するものである。 As a solution to this, in Patent Document 1, the sheets at both ends of the sheet are folded back and joined at regular intervals to form a pocket along the contact edge, and the pocket is filled with earth and sand, and the weight of the pocket pushes the sheet to the ground. Fixed.
In Patent Document 2, the sheets at both ends of the sheet are folded back, and the insides of the sheets are alternately joined at regular intervals to form pockets.
In any of the above methods, pockets are formed at both ends of the sheet, and the pockets are filled with soil before the sheet is attached. It takes more time than piling soil on top, and before collecting the sheet, the soil in the pocket that has been packed once must be taken out from the pocket, which takes considerable time and effort to collect, and it will be covered with mud after rain. Therefore, in order to avoid this, there is a problem such as not being able to collect immediately after a rainy day.

In view of the above, it is an object of the present invention to provide an agricultural cover sheet that can be fixed safely and reliably, which is extremely easy to install and easy to collect.

本発明の農業用被覆シートは略長方形のシートであって、その長辺側の両端を折り返し、折り返しの中央部より内側をシートの長辺に沿って接合して両端に筒状部を構成し、筒状部の長手方向に所定間隔で複数個の貫通孔を設けたことを特徴とする。
本発明の農業用被覆シートの筒状部に棒やパイプ等を通してこれを重りとして活用すると、風でシートが捲れ難く、取り付け作業も極めて容易となる。シートが長い場合は貫通孔から他の棒などをシートの長さ方向に必要本数通すことができる。複数個の貫通孔を設けているので任意の箇所で任意の棒を挿入できる。必要により、前記貫通孔に所定間隔で固定具を通して地面に差し込めば、より強固な固定ができる。 The covering sheet for agriculture of the present invention is a substantially rectangular sheet, and both ends of the long side are folded back, and the inside of the folded back is joined along the long side of the sheet to form cylindrical portions at both ends. A plurality of through holes are provided at predetermined intervals in the longitudinal direction of the cylindrical portion.
If rods, pipes, or the like are passed through the cylindrical portion of the covering sheet for agricultural use of the present invention, and this is used as a weight, the sheet will not be easily blown up by the wind, and the installation work will be extremely easy. If the sheet is long, a necessary number of other rods can be passed through the through holes in the length direction of the sheet. Since a plurality of through holes are provided, arbitrary rods can be inserted at arbitrary positions. If necessary, fixing tools can be passed through the through holes at predetermined intervals and inserted into the ground for stronger fixation.

第２の発明は、前記農業用被覆シートにおいて折り返しと接合により構成された筒状部の一方に、あるいは両方の筒状部に紐を通したことを特徴とする。この紐は柔軟性があり丈夫な紐を使用する。
第２の発明の農業用被覆シートの筒状部に設けた貫通孔に所定間隔で固定具を通し、紐が外側になるように地面に差し込んで紐とシートを大地に固定する。固定具と固定具の間で紐が大地にしっかりと固定されるとともに、筒状部に紐を通しているのでシートも同時に固定され、風で農業用被覆シートが捲れ難く取り付け作業も極めて容易できれいである。 A second aspect of the invention is characterized in that a string is passed through one or both of the cylindrical portions formed by folding and joining the agricultural covering sheet. This string uses a flexible and strong string.
Fixing tools are passed through the through-holes provided in the cylindrical portion of the covering sheet for agriculture of the second invention at predetermined intervals, and are inserted into the ground so that the string faces outward to fix the string and the sheet to the ground. The string is firmly fixed to the ground between the fixtures, and since the string is passed through the tubular part, the sheet is also fixed at the same time. be.

第３の発明の農業用被覆シートは、略長方形のシートのその長辺側の両端を複数回折り返して少なくともシートの重なり枚数を３枚以上とし、前記シートが３枚以上重なった箇所の中央部より内側と外側をシートの長辺に沿ってそれぞれ接合して帯状部を構成し、前記帯状部の長手方向に所定間隔で複数個の貫通孔を設けたことを特徴とする。前記貫通孔は２列の接合部の間に設けるのが望ましい。
第３の発明の農業用被覆シートの帯状部の貫通孔に、所定間隔で固定具を通し地面に差し込んで帯状部を大地に固定する。帯状部は３枚以上のシートが重なり接合されて丈夫な帯状となっているので、固定具と固定具の間も帯状部が大地にしっかりと固定され、風で農業用被覆シートが捲れ難く取り付け作業も極めて容易できれいである。
なお、本発明の農業用被覆シートは、畝に被せる黒色や不織布などのマルチシートや 、地上に支柱を設置しその上に透明や不織布などのビニールシートを被せるビニールトンネルの覆いや、支柱を交差させて支柱間に網を張りエンドウ豆などを栽培する方式の防寒対策用シートとしても用いることができる。
The covering sheet for agriculture according to the third aspect of the present invention is a substantially rectangular sheet whose both ends on the long side are folded back several times so that at least three sheets are overlapped, and the central part of the place where the three or more sheets are overlapped. A belt-like portion is formed by joining the inner side and the outer side along the long side of the sheet, and a plurality of through holes are provided at predetermined intervals in the longitudinal direction of the belt-like portion. Preferably, the through holes are provided between two rows of joints.
Fasteners are passed through the through-holes of the belt-shaped portion of the agricultural covering sheet of the third invention at predetermined intervals and inserted into the ground to fix the belt-shaped portion to the ground. Since the belt-shaped part is formed by overlapping and joining three or more sheets to form a strong belt-shaped part, the belt-shaped part is firmly fixed to the ground even between the fixtures, making it difficult for the agricultural covering sheet to be rolled up by the wind. The work is extremely easy and clean.
In addition, the agricultural covering sheet of the present invention is a mulch sheet such as black or non-woven fabric that covers ridges, a vinyl tunnel cover in which a support is installed on the ground and a vinyl sheet such as transparent or non-woven fabric is placed on it, and a support is crossed. It can also be used as a cold protection sheet for cultivating peas and the like by laying nets between the pillars.

本発明のいずれの農業用被覆シートにおいても、シートを固定するのに土を盛り付けておらず、また、特許文献１や２のようにシートの両端にポケットを設けて、設置時にポケットに土壌を詰めたり、回収前に詰めた土壌を取り出したりする作業がないので、土壌による汚れが少なく、シートの設置作業が簡単で、また、回収するのも容易で、汚れが少ないので回収したシートを再使用することができる。
In any of the agricultural covering sheets of the present invention, soil is not piled to fix the sheet, and pockets are provided at both ends of the sheet as in Patent Documents 1 and 2, and soil is filled in the pockets at the time of installation. Since there is no work to pack the sheets or take out the packed soil before collection, there is little soil contamination, the installation work of the sheets is easy, and it is easy to collect, and since there is little dirt, the collected sheets can be reused. can be used.

本発明の実施形態の例について、図面を参照しながら説明する。 Examples of embodiments of the present invention will be described with reference to the drawings.

本発明にかかわるシートには、材質、厚さ、幅、長さ、透明、不透明、色付き等により色々な種類があり、用途、畝幅、長さなどに合わせて選定される。例えば、寸法では、厚さは０．０２～０．１ｍｍ、幅は９５～６００ｃｍ、長さは５０ｍ，１００ｍ等がある。
畝に直接被せる黒いマルチングフィルムの場合、シートの幅９５ｃｍ、厚さ０．０３ｍｍのポリエチレンフィルムが、ビニールトンネル用の透明フィルムの場合、シート幅は１８０ｃｍ、厚さ０．０３ｍｍのポリエチレンフィルムがよく使用されている。
図１は、本発明に係る農業用被覆シート１０で、シート１の両端部の約１０ｃｍ程度を折り返し、折り返したシート１の端部に近い個所でシート１同士を融着接合した接合部３を設けて筒状部４を形成し、前記筒状部４の長さ方向に所定間隔で５ｃｍ程度の貫通孔５を開けて農業用被覆シート１０は完成する。 完成した農業用被覆シート１０はロール状に巻き取って保管する。 There are various types of sheets according to the material, thickness, width, length, transparency, opacity, coloration, etc., of the sheet according to the present invention. For example, it has a thickness of 0.02 to 0.1 mm, a width of 95 to 600 cm, and a length of 50 m, 100 m, and the like.
For the black mulching film directly covering the ridges, a polyethylene film with a sheet width of 95 cm and a thickness of 0.03 mm is often used, and for a transparent film for vinyl tunnels, a sheet width of 180 cm and a thickness of 0.03 mm is often used. It is
FIG. 1 shows an agricultural covering sheet 10 according to the present invention, in which about 10 cm of both ends of the sheet 1 are folded back, and the sheets 1 are fused and joined near the ends of the folded sheet 1 to form a joint 3. A tubular portion 4 is formed by forming a tubular portion 4, and through holes 5 of about 5 cm are formed at predetermined intervals in the longitudinal direction of the tubular portion 4 to complete the agricultural covering sheet 10. As shown in FIG. The completed agricultural covering sheet 10 is rolled up and stored.

なお、融着接合は通常連続的に接合するが、接合部と非接合部を交互に設ける場合は、接合部の長さが非接合部の長さよりも長い方が好ましい。また、接合方法は融着接合するのが簡便である。
図１の農業用被覆シート１０の筒状部４に長さ２～３ｍの棒を通し、これを農業用被覆シート１０の両側の重りとして機能させる。長い農業用被覆シート１０に対しては、筒状部４に設けた貫通孔５から次の棒を容易に差し込むことができるので、長い農業用被覆シート１０にも対処できる。必要により、前記貫通孔５の所々に固定具１３を通して畝に突き刺せば農業用被覆シート１０をより強固に大地に固定できる。
棒として農業現場でよく使用されている鉄パイプを使う場合、重量があるので鉄パイプと鉄パイプの間隔を大きくして貫通孔５に固定具１３を通して畝に突き刺してもよい。 In addition, fusion bonding is usually performed continuously, but in the case of alternately providing a bonded portion and a non-bonded portion, it is preferable that the length of the bonded portion is longer than the length of the non-bonded portion. Also, as a joining method, it is convenient to use fusion joining.
A rod having a length of 2 to 3 m is passed through the cylindrical portion 4 of the agricultural covering sheet 10 of FIG. Since the next rod can be easily inserted into the long agricultural covering sheet 10 from the through hole 5 provided in the tubular portion 4, the long agricultural covering sheet 10 can also be dealt with. If necessary, the agricultural covering sheet 10 can be more firmly fixed to the ground by inserting the fasteners 13 through the through holes 5 and piercing the ridges.
When iron pipes, which are often used in agricultural fields, are used as the rods, since they are heavy, the distance between the iron pipes may be increased, and the fasteners 13 may be passed through the through holes 5 and pierced into the ridges.

図２は第２の本発明に係る農業用被覆シート１１で、第１の発明の農業用被覆シート１０の筒状部４の中に柔軟で丈夫な紐６を通した構成としている。紐６は農業用被覆シート１１と同等以上の長さを有している。農業用被覆シート１１を長さ方向に引っ張って、筒状部４に開けられた貫通孔５を通して所定間隔で固定具１３を大地に差し込んでシート１と紐６を固定する。筒状部４に紐６を通しているので、固定具１３と固定具１３の間も紐６で農業用被覆シート１１が大地にしっかりと固定され、風でシートが捲れ難く取り付け作業も極めて容易である。 FIG. 2 shows an agricultural covering sheet 11 according to the second invention, which has a configuration in which a flexible and strong cord 6 is passed through the cylindrical portion 4 of the agricultural covering sheet 10 according to the first invention. The string 6 has a length equal to or greater than that of the agricultural covering sheet 11. - 特許庁The covering sheet 11 for agriculture is pulled in the longitudinal direction, and the sheet 1 and the string 6 are fixed by inserting the fixtures 13 into the ground at predetermined intervals through the through holes 5 formed in the tubular part 4. - 特許庁Since the string 6 is passed through the cylindrical part 4, the covering sheet 11 for agriculture is firmly fixed to the ground by the string 6 also between the fixtures 13 and the fixtures 13, and the sheet is hardly turned up by the wind, and the mounting work is extremely easy. .

For a long agricultural covering sheet 10, the next raw bamboo 16 can be easily inserted through the through hole 5 provided in the cylindrical portion 4, so that the long agricultural covering sheet 10 can also be handled. If necessary, the fasteners 13 can be passed through the through holes 5 and inserted into the ridges 15 for stronger fixation. The weight effect can be further improved by using iron pipes commonly used in farms instead of raw bamboo 16 .
In the case of collecting the raw bamboo 16, it is only necessary to pull out the raw bamboo 16 from the cylindrical part 4 and pull out the fixture 13. Since there is no need to put soil into the pocket or scrape it out, the work is clean and simple without being soiled with mud. The cover sheet 10 for use can be reused because it is less soiled.

図７は本発明の農業用被覆シート１１を畝１５のマルチングに適用した例を示す。シート１は黒で不透明のものを使用する。４は筒状部、５は筒状部に設けた貫通孔、６は紐、１３はT字状の固定具であり紐６と農業用被覆シート１１を大地に固定する。固定具１３は紐６が外側になるように差し込む。筒状部４に紐６を通しているので、固定具１３と固定具１３の間の筒状部４は紐６で大地にしっかりと固定されるので、風で農業用被覆シート１１が捲れ難く、取り付け作業も極めて容易である。
回収する場合も、固定具１３を引き抜くだけでよく、ポケットへの土壌投入や掻き出しもないので泥で汚れることもなく、作業がきれいで紐６は柔軟性があるので回収作業が簡単で、回収した農業用被覆シート１１は汚れが少ないので再使用することができる。 FIG. 7 shows an example of applying the agricultural covering sheet 11 of the present invention to mulching of ridges 15 . Sheet 1 is black and opaque. 4 is a tubular portion, 5 is a through hole provided in the tubular portion, 6 is a string, and 13 is a T-shaped fixture for fixing the string 6 and the agricultural covering sheet 11 to the ground. The fixture 13 is inserted so that the string 6 is on the outside. Since the string 6 is passed through the tubular part 4, the tubular part 4 between the fixtures 13 is firmly fixed to the ground by the string 6, so that the covering sheet 11 for agricultural use is not easily rolled up by the wind. Work is also extremely easy.
In the case of collecting, it is only necessary to pull out the fixing tool 13, and since there is no need to throw soil into the pocket or scrape it out, there is no soiling with mud. The agricultural covering sheet 11 which has been cleaned can be reused because it is less soiled.

図８は本発明の農業用被覆シート１２を畝１５のマルチングに適用した例を示す。農業用被覆シート１２も他の農業用被覆シート１０、１１と同様な使用方法ができる。帯状部７は複数枚のシート１を重ねて融着接合され、丈夫な帯となっているので、T字状の固定具１３を貫通孔５に通して畝１５に差し込むことにより、固定具１３と固定具１３の間も帯状部７が大地にしっかりと固定されるので、風で農業用被覆シート１２が捲れ難く、取り付け作業も極めて容易である。
回収する場合も、固定具１３を引き抜くだけでよく、特許文献１や２のようにポケットへの土壌投入や掻き出しもないので泥で汚れることもなく、回収した農業用被覆シート１２は汚れが少ないので再使用することができる。 FIG. 8 shows an example of applying the agricultural covering sheet 12 of the present invention to mulching of ridges 15 . The agricultural covering sheet 12 can also be used in the same manner as the other agricultural covering sheets 10 and 11 . Since the band-shaped portion 7 is formed by stacking a plurality of sheets 1 and fusion-bonding them to form a strong band, the fixing member 13 can be secured by inserting the T-shaped fixing member 13 through the through hole 5 into the ridge 15. Since the band-shaped part 7 is firmly fixed to the ground also between the fixing member 13 and the cover sheet 12 for agriculture, it is difficult for the wind to turn over the covering sheet 12, and the installation work is extremely easy.
In the case of collecting, it is only necessary to pull out the fixture 13, and unlike Patent Documents 1 and 2, the soil is not put into the pocket or scraped out, so the collected agricultural covering sheet 12 is less soiled. so it can be reused.

本発明に係る農業用被覆シート１０，１１，１２は、固定するのにシートのポケットに土壌を詰めたり、回収する前に詰めた土壌を掻き出したりする作業がなく、筒状部４に棒の出し入れや固定具１３の大地への差し込み引き抜きだけでよく、設置作業や回収作業が簡単で土壌による汚れが少なく、また、回収したシートは汚れが少ないので再使用することができる。
The agricultural covering sheets 10, 11, and 12 according to the present invention do not need to be filled with soil in the pockets of the sheets for fixing, and the work of raking out the filled soil before collection is not required. It is only necessary to insert and remove the fixture 13 from the ground, and the installation work and collection work are simple, and the collected sheet is less soiled and can be reused.
