Description

本発明は、植林用のブロックに関するものである。 The present invention relates to a plantation block.

植林のため原野や伐採跡地に植えた小さな苗木は、植林後数年間は、その周囲の雑草を刈り払う必要がある。雑草の刈り払いにはエンジンを具えた草刈機が用いられており、苗木が小さい場合、雑草と苗木を判別して、雑草のみを刈り払う方法がとられている。
一方、草刈りの手間を省くために、植林の際に苗木の回りにシートやフィルムを張る方法なども知られている（例えば、特許公開２０００−９３０１２など）。 Small seedlings planted in the wilderness or logging sites for planting need to mow the surrounding weeds for several years after planting. A mowing machine equipped with an engine is used to trim the weeds. When the seedlings are small, the weeds and seedlings are discriminated and only the weeds are trimmed.
On the other hand, in order to save the labor of mowing, a method of stretching a sheet or film around a seedling at the time of planting is also known (for example, Patent Publication 2000-93012).

しかしながら、苗木が小さい場合、苗木が雑草の中に紛れて判別がし難く、エンジンを具えた草刈機で誤って苗木まで切断する危険性があった。
一方、シートやフィルムを安定的に設置するためには、多数の杭でしっかり止める必要があり、この杭打ち作業に相当の労力が必要になるという課題があった。
特開平５−２１９８０４号公報特開２０００−９３０１２号公報実開平５−９１３６５号公報 However, when the seedlings are small, the seedlings are difficult to distinguish because they are mixed in the weeds, and there is a risk of accidentally cutting the seedlings with a mower equipped with an engine.
On the other hand, in order to stably install a sheet or a film, it is necessary to firmly secure it with a large number of piles, and there has been a problem that considerable labor is required for this pile driving work.

解決しようとする問題点は、苗木の成長の妨げとなる雑草が生える点と、その雑草を刈り払う際に苗木まで切除してしまう恐れがある点である。 The problem to be solved is that weeds that hinder the growth of the seedlings grow and that the seedlings may be cut off when the weeds are cut off.

本発明は、植林された苗木の位置を目視で確認しやすくすると共に、雑草を生えにくくするために、苗木の周囲を複数個のブロック部材からなるブロックで囲むようにすることを最も主要な特徴とする。 The main feature of the present invention is to surround the seedling with a block made up of a plurality of block members in order to make it easy to visually confirm the position of the planted seedling and to make it difficult to grow weeds. And

本発明の植林用ブロックは、複数のブロック部材を植林した苗木の周囲に置くだけで、雑草の抑制が可能であり、万一ブロック周囲の雑草が苗木周囲までつたっても、ブロック自体が目視で容易に見つかるので、エンジンを具えた草刈機での雑草の刈り払いでも苗木を誤って切ってしまうことがほとんどないという利点がある。 The block for afforestation of the present invention can suppress weeds by simply placing a plurality of block members around the planted seedling, and even if the weed around the block reaches the periphery of the seedling, the block itself cannot be visually observed. Since it is easily found, there is an advantage that the seedlings are hardly cut by mistake even when the weeds are cut off with a mower equipped with an engine.

雑草を抑制し苗木の位置を確認しやすくするという目的を、複数のブロックを組合せることにより実現した。 The purpose of controlling weeds and making it easier to confirm the position of seedlings was realized by combining multiple blocks.

図１は、本発明植林用ブロックの平面図である。符号１０は、第１のブロック部材で、２０は、第２のブロック部材である。なお、本実施例では、ブロック部材を半ドーナツ形として２つ示しているが、これに限らず、形状は多角形を分割した形であってもよいし、個数は３つ以上の複数個であってもよい。 FIG. 1 is a plan view of the afforestation block of the present invention. Reference numeral 10 is a first block member, and 20 is a second block member. In this embodiment, two block members are shown as half donuts. However, the shape is not limited to this, and the shape may be a polygonal shape, and the number may be three or more. There may be.

第１のブロック部材１０は、例えばコンクリートからなり、厚さは１〜５ｃｍが、重さは１〜５ｋｇが好ましい。厚さと重さは、耐久性、運搬性及び強風に対する安定性の点を考慮して定められる。厚さ１ｃｍ未満又は重さ１ｋｇ未満では雑草を押さえる力や強風時の安定性が不足するし、厚さ５ｃｍ超又は重さ５ｋｇ超では運搬性が低下するため好ましくない。 The first block member 10 is made of, for example, concrete, and preferably has a thickness of 1 to 5 cm and a weight of 1 to 5 kg. The thickness and weight are determined in consideration of durability, transportability and stability against strong winds. If the thickness is less than 1 cm or the weight is less than 1 kg, the force to suppress weeds and the stability at the time of strong wind are insufficient, and if the thickness exceeds 5 cm or the weight exceeds 5 kg, the transportability is lowered, which is not preferable.

第１のブロック部材１０は、半ドーナツ状であり、第１の辺（または弦）１２の略中央部には、第１の切欠１４が設けられている。この第１の切欠１４の周囲には、雨水を集めるための段差１６と１つ以上の通水孔１８（孔の内径１ｃｍ程度）が設けられている。第１の辺１２の長さ、即ち本発明ブロックの外径は２０〜４０ｃｍが好適であり、３０ｃｍ程度が視認性、運搬性の点から最適である。外径が２０ｃｍ未満では雑草の中での視認性が不足し、外径が４０ｃｍを超えると大きくて、重くて運搬性が低下するため好ましくない。またブロック部材の色は、視認性の点から白色系、黄色系、赤色系、青色系などが好適である。 The first block member 10 has a half donut shape, and a first notch 14 is provided at a substantially central portion of the first side (or string) 12. Around the first cutout 14, there are provided a step 16 for collecting rainwater and one or more water holes 18 (inner diameter of the hole is about 1 cm). The length of the first side 12, that is, the outer diameter of the block of the present invention is preferably 20 to 40 cm, and about 30 cm is optimal from the viewpoint of visibility and transportability. If the outer diameter is less than 20 cm, the visibility in the weeds is insufficient, and if the outer diameter exceeds 40 cm, it is large and heavy, and the transportability is lowered. Further, the color of the block member is preferably white, yellow, red or blue from the viewpoint of visibility.

第２のブロック部材２０は、半ドーナツ状であり、第２の辺（または弦）２２の略中央部には、第２の切欠２４が設けられている。この第２の切欠２４の周囲には、雨水を集めるための段差２６と１つ以上の通水孔２８（孔の内径１ｃｍ程度）が設けられている。なお、本実施例では第２のブロック部材２０と第１のブロック部材１０は、１８０度回転しているが、同一の形状である。 The second block member 20 has a half donut shape, and a second notch 24 is provided at a substantially central portion of the second side (or string) 22. Around the second cutout 24, there are provided a step 26 for collecting rainwater and one or more water passage holes 28 (the inner diameter of the hole is about 1 cm). In the present embodiment, the second block member 20 and the first block member 10 are rotated 180 degrees, but have the same shape.

第１および第２の切欠１４，２４によって、苗木用孔（内径３〜６ｃｍ程度が好適）が形成され、この苗木用孔に苗木の根元が入るように、第１および第２のブロック部材１０，２０を配置して、植林用ブロックを構成する。第１および第２のブロック部材１０，２０は平板状に限らず、苗木根元の土の盛り上がりにすり合わせ易いように、苗木用孔側を上方に膨らませたが好適である。また、ブロック部材の組み合わせ部分に隙間が生じないように、辺１２と辺２２の部分には段差を設けて上下に重なる部分を設けたが好適である。 The first and second cutouts 14 and 24 form a seedling hole (an inner diameter of about 3 to 6 cm is preferable), and the first and second block members 10 so that the roots of the seedlings enter the hole for the seedling. , 20 are arranged to constitute a tree planting block. The first and second block members 10 and 20 are not limited to a flat plate shape, but it is preferable that the seedling hole side is inflated upward so that it can be easily rubbed with the soil at the root of the seedling. Further, it is preferable to provide a portion overlapping the top and bottom by providing a step in the side 12 and side 22 parts so that no gap is generated in the combination part of the block members.

本発明の植林用ブロックは、植林した苗木の周囲に置くだけで、雑草の抑制が可能となる。万一、ブロック周囲の雑草が苗木周囲までつたっても、ブロック自体が目視で容易に確認できるので、エンジンを具えた草刈機での雑草刈り払いに際して、苗木を誤切断することはほとんどなくなるという効果がある。 The block for planting of the present invention can suppress weeds only by placing it around the planted seedling. Even if weeds around the block reach the seedlings, the block itself can be easily confirmed visually, so there is almost no mistakenly cutting the seedlings when weeding with a mower equipped with an engine. There is.

本発明の植林用ブロック部材の材質は、特に限られることはないが、コンクリート、レンガ、石膏、陶磁器、木、紙、合成樹脂などを用いることができる。要は、遮光性があって、目視による確認が容易なものであれば良い。繰り返して利用をする場合の材質は、コンクリートやレンガ、陶磁器が好適である。いわゆる使い捨ての１回だけ使用の場合は、溶解性のある石膏や生分解性を有する木、紙、生分解性プラスチックなどが好ましい。 Although the material of the block member for tree planting of this invention is not specifically limited, Concrete, brick, gypsum, ceramics, wood, paper, a synthetic resin, etc. can be used. In short, any material that has light shielding properties and can be easily visually confirmed is acceptable. Concrete, bricks, and ceramics are suitable as materials for repeated use. In the case of so-called disposable one-time use, soluble plaster, biodegradable wood, paper, biodegradable plastic, and the like are preferable.

本発明の植林用ブロックをコンクリートや石膏などで、外径３０ｃｍ程度の大きさ、１個の重量１〜５ｋｇ程度で作成すれば、原野や伐採跡地などへ容易に搬入でき、植林に際して簡単に設置できる。
設置したブロックの直下部分は雑草が抑制され、ブロックの周囲の雑草が伸びても植林した苗木と雑草の判別はブロックの存在により容易になるため草刈作業の能率が高くなる。また、杉やヒノキなどの伝統的な植林は傾斜が大きい土地でもなされるが、そのような場合は通水孔に生分解性のある杭（割り箸など）を打ち込めばブロックを地面に固定することができる。このようにして植林用ブロックを使用することにより、傾斜や雑草など阻害要因が多い原野や伐採跡地における植林事業を容易かつ効率的にし、植林した木によって森を作るという林業に役立てることができる。 If the block for afforestation of the present invention is made of concrete, plaster, etc. with an outer diameter of about 30 cm and a weight of about 1 to 5 kg, it can be easily carried into the wilderness or logging site, and installed easily at the time of afforestation it can.
Weeds are suppressed immediately below the installed block, and even if weeds around the block grow, discrimination of planted seedlings and weeds becomes easy due to the presence of the block, so the efficiency of mowing work increases. In addition, traditional plantations such as cedar and hinoki are made even on land with a large slope. In such cases, a block can be fixed to the ground by placing a biodegradable pile (such as disposable chopsticks) in the water passage. Can do. By using afforestation blocks in this way, afforestation projects can be made easier and more efficient in fields and logging sites where there are many obstruction factors such as slopes and weeds, and this can be used for forestry where forests are created from planted trees.
