Description
【０００１】[0001]
本考案は、例えば屋上等に投入される屋上植栽用土壌として好適な人工組合せ 土壌に関する。詳細には軽量であると共に、高い保水性及び通気性と豊富な肥料 成分を有する人工組合せ土壌に関する。 INDUSTRIAL APPLICABILITY The present invention is an artificial combination suitable as a soil for rooftop planting to be put on a rooftop, for example. Regarding soil. In particular, it is lightweight, highly water-retaining and breathable, and abundant fertilizer. It relates to an artificial combined soil with components.
【０００２】[0002]
近年、世界的に地球環境の保全が叫ばれる中、特には地球温暖化について、そ の根源とされる二酸化炭素の吸収源として、また生物多様性保全上も重要な役割 を担う森林。この森林吸収源対策の推進が重要な課題として検討されている。 In recent years, there has been a worldwide call for conservation of the global environment. As an absorption source of carbon dioxide, which is the root of the forest, and an important role in biodiversity conservation Forest that bears. Promotion of measures for forest sinks is being considered as an important issue.
【０００３】 森林吸収源対策として、奥山、里山の森林の保全、整備を進める一方で、都市 緑化、都市周辺における森林再生が実施されている。特に都市緑化に着目したと き、その具体例としては、道路脇や中央分離帯あるいは公園への植樹、建築物の 屋上やベランダ、バルコニー等への植樹がある。[0003] While promoting the conservation and maintenance of forests in Okuyama and Satoyama as measures to absorb forests, Greening and reforestation around the city are being implemented. Especially when focusing on urban greening The specific examples are tree planting on roadsides, medians or parks, Trees are planted on the rooftop, verandas, balconies, etc.
【０００４】 建築物の屋上やベランダ、バルコニー等への植樹（以下、屋上緑化という）は 、森林吸収源対策という役割だけではなく、建築物内外部の断熱効果、大気浄化 、建築物の美観向上という効果が期待でき、しかも屋上緑化は国や地方公共団体 に限らず、民間企業や一般家庭でも実施することができる。[0004] Tree planting on the rooftops of buildings, balconies, balconies, etc. , Not only the role of measures for forest sinks, but also the heat insulation effect inside and outside the building, air purification , The effect of improving the aesthetics of the building can be expected, and the rooftop greening is a national or local public entity. It can be implemented not only by private companies but also by ordinary households.
【０００５】 このような事情から、屋上緑化は実施されつつあるが、その実施に際しては、 様々な障害があり、未だ広く普及していないのが現状である。例えば建築物の屋 上やベランダ、バルコニー等へ植樹して屋上緑化を実施する場合、建築物への載 荷荷重が１８０ｋｇ／ｍ2を越えてはならないという建築基準法上に定められた 制限がある。Under these circumstances, rooftop greening is being implemented, but there are various obstacles to its implementation, and the current situation is that it has not yet become widespread. For example, when a tree is planted on the rooftop of a building, a balcony, a balcony, etc. to carry out greening on the rooftop, there is a limit set by the Building Standard Law that the load on the building must not exceed 180 kg / m 2 .
【０００６】 ところが、従来、山砂などの天然土材を屋上等に投入して盛土し、これに植栽 を施した場合、山砂などの天然土材の比重が大きいため、山砂などの天然土材だ けで施工ができなかった。一方、載荷荷重の制限を考慮して盛土を小さくした場 合には、浅根性樹種や低木類など植栽できる植物の種類が制限された。[0006] However, in the past, natural earth materials such as mountain sand were put on the rooftop to embank and planted on this. When applied, since the specific gravity of natural earth materials such as mountain sand is large, it is a natural earth material such as mountain sand. The construction was not possible due to the injury. On the other hand, if the embankment is made small in consideration of the load limit. In this case, the types of plants that can be planted such as shallow root species and shrubs were limited.
【０００７】 そこで、バーミキュライトなどの軽量で保水性に富む無機性多孔質体を用いた 人工土壌も提案されるに至っているが、この土壌の場合には、山砂などの天然土 材に比べてｐＨが弱アルカリ性ないし中性であり、植物根の伸長に最適な土壌物 理条件を保てないという不具合があった。[0007] Therefore, we used an inorganic porous material such as vermiculite that is lightweight and rich in water retention. Artificial soil has also been proposed, but in the case of this soil, natural soil such as mountain sand is used. Soil material that has a slightly alkaline or neutral pH compared to wood and is ideal for growing plant roots There was a problem that we could not keep the logical conditions.
【０００８】 本考案は、このような事情に鑑みなされたものであり、軽量であり、屋上等に 投入して盛土した場合でも、建築基準法上に定められた建築物への載荷荷重の制 限をクリアすることができ、しかも高い保水性及び通気性と豊富な肥料成分を有 する人工組合せ土壌を提供することを目的とするものである。[0008] The present invention has been made in view of such circumstances, is lightweight, and is suitable for rooftops and the like. Even if the material is thrown in and embankd, it is possible to control the load applied to the building specified by the Building Standards Act. It has a high water retention and breathability and abundant fertilizer components. The purpose of the present invention is to provide an artificial combined soil.
【０００９】[0009]
上記目的を達成するため、本考案は、天然土材と木材チップと無機多孔質体の 物品の組合せからなり、前記天然土材と木材チップと無機多孔質体が、容積比で １：２：２〜１：２：３の割合で組み合わされており、比重が０．７〜０．９で あることを特徴とする人工組合せ土壌をその要旨とした。 In order to achieve the above object, the present invention provides a natural soil material, wood chips, and an inorganic porous material. Composed of a combination of articles, the natural soil material, wood chips and inorganic porous material in volume ratio They are combined at a ratio of 1: 2: 2 to 1: 2: 3 and have a specific gravity of 0.7 to 0.9. The feature is an artificial combination soil which is characterized.
【００１０】 この人工組合せ土壌において、天然土材としては、真砂土または黒ボク土のい ずれか１種を好ましい例として挙げることができる。これらの天然土材には植物 の生育に必要な肥料成分が豊富に含まれており、特に黒ボク土は、赤黄色土など の他の天然土材に比べて比重が軽いという利点があり、真砂土については安価で あるという利点がある。また、本考案の天然土材としては、前記真砂土と黒ボク 土の混和物という形態で用いることもできる。[0010] In this artificial combination soil, the natural soil material is sand sand or black soil. One of them may be mentioned as a preferable example. These natural soils are plants It contains abundant fertilizer components necessary for plant growth. Compared with other natural soil materials, it has the advantage of being lighter in specific gravity, and it is cheaper for sand sand. There is an advantage. The natural soil material of the present invention includes the sand sand and the black sand It can also be used in the form of a mixture of soil.
【００１１】 木材チップは、該人工組合せ土壌に有機質分を付与する成分である。木材チッ プとしては、樹木の枝や幹をチップ状に破砕した木質チップ、樹皮チップ、樹皮 付き木質チップなどが挙げられる。好ましくは剪定時に生じる木屑や朽ち木や枯 れ木（廃材）をチップ状に破砕した破砕物である。木材チップの大きさとしては 、直径が８．０〜１０．０ｍｍであって、長さが８．０〜１０．０ｍｍの大きさ に破砕したものが望ましい。木材チップの大きさは基本的には自由であるが、直 径及び長さを上記範囲とした場合には、取り扱い性が良好となるというメリット がある。[0011] Wood chips are components that impart organic matter to the artificial combined soil. Wood chip The wood chips, bark chips, and bark obtained by crushing the branches and trunks of trees into chips. Such as wood chips with attached. Preference is given to wood chips, decayed trees and withering that occur during pruning It is a crushed material obtained by crushing wood (waste wood) into chips. As for the size of wood chips , The diameter is 8.0 to 10.0 mm and the length is 8.0 to 10.0 mm It is desirable to crush it into pieces. The size of wood chips is basically free, but When the diameter and length are in the above range, the merit of good handling There is.
【００１２】 木材チップとして木屑の破砕物を用いる場合、木屑の破砕物をそのまま他の成 分と配合しても良いが、発酵した木屑の破砕物を用いることもできる。発酵した 木屑の破砕物としては、自然発酵したものの他に、例えば鶏糞や油かすなどの窒 素源を加えて好気性発酵させるなど従来公知の発酵方法により発酵処理したもの も使用できる。発酵処理した木屑の破砕物を用いた場合、発酵処理に使用する窒 素源がそのまま窒素肥料成分として破砕物中に残存するという利点がある。[0012] When using crushed wood chips as wood chips, the crushed wood chips are used as is for other processes. Although it may be mixed with the minced meat, it is also possible to use a crushed product of fermented wood chips. Fermented In addition to naturally fermented wood chips, for example, debris such as chicken manure and oil dregs Fermented by a conventionally known fermentation method such as aerobic fermentation by adding a source Can also be used. If crushed material of fermented wood chips is used, There is an advantage that the elemental source remains as it is as a nitrogen fertilizer component in the crushed material.
【００１３】 尚、発酵の程度としては、木屑の破砕物がその原形を留める程度にしたものが 望ましい。また、発酵した木屑の破砕物を用いる場合、これに乾留処理を行って 、破砕物中の水分及びタール分を除去することで、該木屑の破砕物の軽量化を計 ることもできる。[0013] As for the degree of fermentation, crushed wood chips retain their original shape. desirable. Also, when using crushed material of fermented wood chips, dry distillation treatment is applied to this. By removing the water and tar content from the crushed material, the weight of the crushed wood waste can be reduced. You can also do it.
【００１４】 無機多孔質体としては、パーライトまたはバーミキュライトのいずれか、また はこれらの混和物が好ましい。パーライトとしては、真珠岩を８００〜１０００ ℃で焼成発泡させたものや、黒曜石を８００〜１０００℃で焼成発泡させたもの であって、比重が０．２５〜０．５のものが好ましい。このパーライトは高温処 理のため、無毒、無臭、無菌であり、このパーライトを含ませることで、該人工 組合せ土壌に優れた保水性と通気性が付与されることになる。[0014] As the inorganic porous material, either perlite or vermiculite, Are preferably mixtures of these. Pearlite is 800-1000 as perlite Those that have been fired and foamed at ℃ or those that have had obsidian fired and foamed at 800 to 1000 ℃ It is preferable that the specific gravity is 0.25 to 0.5. This perlite is high temperature Therefore, it is nontoxic, odorless, and sterile, and by including this perlite, the artificial Excellent water retention and air permeability will be imparted to the combined soil.
【００１５】 バーミキュライトは、片磨岩や結晶片岩等の中に含まれる蛭石を８００〜１０ ００℃の高熱で焼成加工し、薄片の層の間にある微量の結晶水・構造水を水蒸気 として膨張させた多孔質体であり、その比重は０．１〜０．５のものが好ましい 。[0015] Vermiculite is a vermiculite contained in schist and crystal schist. It is baked at a high temperature of 00 ° C and a small amount of crystal water / structure water between the layers of flakes is steamed. It is a porous body that is expanded as, and its specific gravity is preferably 0.1 to 0.5 .
【００１６】 このバーミキュライトは高熱処理により製造されているため、有害な菌や雑草 の種子を含まず、多孔質のため吸水力が極めて強く、空気の流通を良好とし、肥 料成分であるカリを含有し、窒素の吸着性をも持っている。[0016] This vermiculite is manufactured by high heat treatment, so harmful bacteria and weeds It does not contain seeds, and because it is porous, it has a very strong water absorption, which improves the air circulation and fertilizer. It contains potassium, which is a raw material, and also has a nitrogen adsorption property.
【００１７】 上記パーライト及びバーミキュライトは、Ｎａ，Ｋ，Ｃａ，Ｍｇ等の塩基性陽 イオンを吸着し易く（ＣＥＣ値が高い）、かつ、ＮＨ4 イオンを保持して、Ｎ， Ｐ，Ｋ等の肥効率も向上させると共にＮＨ3 ガスの揮散を抑制する性質を持つ。[0017] The above-mentioned perlite and vermiculite are basic cations such as Na, K, Ca and Mg. It is easy to adsorb ions (high CEC value) and retains NH4 ions, It has the property of improving the fertilizing efficiency of P, K, etc. and suppressing the volatilization of NH3 gas.
【００１８】 本考案の人工組合せ土壌は、上記天然土材と木材チップと無機多孔質体が、容 積比で１：２：２〜１：２：３の割合で組み合わされ、その比重が０．７〜０． ９となっている。上記範囲よりも天然土材量が多い場合、該人工組合せ土壌の比 重が大きくなり、少ない場合には植物の生育に適切な土壌物理条件や最適ｐＨが 保持できなくなる。[0018] In the artificial combined soil of the present invention, the natural soil material, wood chips and inorganic porous material are They are combined at a ratio of 1: 2: 2 to 1: 2: 3 and have a specific gravity of 0.7 to 0. It is 9. When the amount of natural soil material is larger than the above range, the ratio of the artificial combined soil When the weight is large and the weight is small, the soil physical conditions and optimum pH suitable for plant growth are It becomes impossible to hold.
【００１９】 一方、木材チップ量が上記範囲よりも多い場合には、該人工組合せ土壌の軽量 化は進むが、保水性が低下し、ＣＥＣ値も小さくなるというデメリットがある。 また木材チップ量が上記範囲よりも少ない場合には有機質分が少なくなる。また 、無機多孔質体量が上記範囲よりも多い場合、保水性が高くなり、ＣＥＣ値も高 くなる反面、軽量化に伴う飛散の恐れや、植物の生育に必要な土壌物理条件が保 持できなくなる。[0019] On the other hand, when the amount of wood chips is larger than the above range, the weight of the artificial combination soil is light. However, there is a demerit that the water retention is reduced and the CEC value is also reduced. When the amount of wood chips is less than the above range, the organic matter content is small. Also If the amount of the inorganic porous material is larger than the above range, the water retention becomes high and the CEC value becomes high. On the other hand, there is a risk of scattering due to weight reduction, and soil physical conditions necessary for plant growth are maintained. I can't hold it.
【００２０】 本考案の人工組合せ土壌は、ＣＥＣが５．０〜６．０ｍｅ／１００ｇの範囲と なっている。前述の如くその範囲は、天然土材と木材チップと無機多孔質体の物 品の組合せの割合で決まる。ＣＥＣ値を５．０〜６．０ｍｅ／１００ｇの範囲と することで、植物の生育に必要な肥料成分が確保されることになる。[0020] The artificial combined soil of the present invention has a CEC of 5.0 to 6.0 me / 100 g. Has become. As mentioned above, the range is made of natural earth materials, wood chips and inorganic porous materials. Determined by the ratio of product combinations. CEC value in the range of 5.0-6.0me / 100g By doing so, the fertilizer components necessary for plant growth can be secured.
【００２１】 本考案の人工組合せ土壌は、比重が０．７〜０．９であることから、例えば建 築物の屋上、ベランダ、バルコニー等に投入される屋上植栽用土壌として好適な 土壌である。またこの人工組合せ土壌は、橋やダムなどの土木構造物に造成され る道路脇などに植樹するときに用いることもできる。また、大型客船や洋上フロ ート上へ植樹する際にも、植栽用土壌として適用することができる。[0021] Since the artificial combined soil of the present invention has a specific gravity of 0.7 to 0.9, Suitable as a soil for rooftop planting that is put on the roof of a structure, veranda, balcony, etc. It is soil. In addition, this artificial combination soil was constructed in civil engineering structures such as bridges and dams. It can also be used when planting trees on the side of a road. Also, large passenger ships and offshore flores It can be applied as a soil for planting even when planting trees on a tree.
【００２２】 本考案の人工組合せ土壌は、天然土材と木材チップと無機多孔質体の物品を組 合せただけの形態の他に、ブロック状や板状などの形状に成形することもできる 。この場合、該人工組合せ土壌は、ブロックや板として取り扱うことができ、運 搬など取り扱い性が頗る良い。この人工組合せ土壌をブロック状や板状とする場 合、例えば図２０に示すように、ブロック状または板状をなすプラスチック製の 袋体２０に天然土材と木材チップと無機多孔質体の物品を組合せた人工組合せ土 壌１０を詰め込んで成形することができる。[0022] The artificial combination soil of the present invention is a combination of natural soil material, wood chips, and inorganic porous material. In addition to the combined shape, it can be molded into a block shape, a plate shape, or the like. . In this case, the artificial combined soil can be handled as a block or plate, Good handling such as carrying. If you want to make this artificial combined soil into blocks or plates For example, as shown in FIG. 20, for example, a block-shaped or plate-shaped plastic Artificial combination soil in which bag 20 is combined with natural soil material, wood chips, and inorganic porous article The loam 10 can be packed and molded.
【００２３】 図２１に示すものは、両端に取っ手孔２１を設けたブロック状の袋体２０内に 人工組合せ土壌１０を詰め込んで、人工組合せ土壌１０をブロック状に成形した ものである。この形態の場合、人工組合せ土壌１０は袋体２０の取っ手２１を掴 んで持ち運びができ、取り扱い性がさらによい。[0023] The one shown in FIG. 21 is a block-shaped bag body 20 having handle holes 21 at both ends. The artificial combined soil 10 was packed, and the artificial combined soil 10 was formed into a block shape. It is a thing. In the case of this form, the artificial combined soil 10 holds the handle 21 of the bag body 20. It is portable and easy to handle.
【００２４】 図２２に示すものは、中央に袋の表裏に貫通する孔２２を設けたブロック状袋 体２０内に人工組合せ土壌１０を詰め込んで、人工組合せ土壌１０を中央に貫通 孔１１を有するブロック状に成形したものである。この形態の場合、運搬時や取 り扱い時にはこの孔１１または２１に手をかけて取り扱うことができ、より便利 である。また、この形態の場合には、人工組合せ土壌１０は袋体２０と共に中央 に貫通孔１１を有するブロック状に成形されるので、保管時には袋体２０の孔２ ２を合わせて多数上下に積み重ね、連通した孔に棒体を挿入するなどすることで 、荷崩れを防止することができるというメリットがある。[0024] The one shown in FIG. 22 is a block-shaped bag having a hole 22 penetrating the front and back of the bag in the center. Pack the artificial combined soil 10 in the body 20 and penetrate the artificial combined soil 10 in the center. It is formed in a block shape having holes 11. In the case of this form, When handling it, you can handle it by putting your hand into this hole 11 or 21. Is. Moreover, in the case of this form, the artificial combined soil 10 is centered with the bag body 20. Since it is formed into a block shape having a through hole 11 in its inside, the hole 2 of the bag body 20 is stored during storage. By stacking 2 together and stacking them up and down, and inserting rods into the communicating holes, There is a merit that it is possible to prevent the collapse of the load.

本考案は、例えば屋上等に投入される屋上植栽用土壌として好適な人工組合せ 土壌をブロック状の袋体に詰め込んで成形したブロック状土壌に関する。This invention relates to a block-like soil molded packed suitable artificial combinations soil block-type body as roof planting soil is introduced, for example, the roof or the like.
近年、世界的に地球環境の保全が叫ばれる中、特には地球温暖化について、そ の根源とされる二酸化炭素の吸収源として、また生物多様性保全上も重要な役割 を担う森林。この森林吸収源対策の推進が重要な課題として検討されている。 森林吸収源対策として、奥山、里山の森林の保全、整備を進める一方で、都市 緑化、都市周辺における森林再生が実施されている。特に都市緑化に着目したと き、その具体例としては、道路脇や中央分離帯あるいは公園への植樹、建築物の 屋上やベランダ、バルコニー等への植樹がある。 建築物の屋上やベランダ、バルコニー等への植樹（以下、屋上緑化という）は 、森林吸収源対策という役割だけではなく、建築物内外部の断熱効果、大気浄化 、建築物の美観向上という効果が期待でき、しかも屋上緑化は国や地方公共団体 に限らず、民間企業や一般家庭でも実施することができる。 このような事情から、屋上緑化は実施されつつあるが、その実施に際しては、 様々な障害があり、未だ広く普及していないのが現状である。例えば建築物の屋 上やベランダ、バルコニー等へ植樹して屋上緑化を実施する場合、建築物への載 荷荷重が１８０ｋｇ／ｍ2を越えてはならないという建築基準法上に定められた 制限がある。 ところが、従来、山砂などの天然土材を屋上等に投入して盛土し、これに植栽 を施した場合、山砂などの天然土材の比重が大きいため、山砂などの天然土材だ けで施工ができなかった。一方、載荷荷重の制限を考慮して盛土を小さくした場 合には、浅根性樹種や低木類など植栽できる植物の種類が制限された。 そこで、バーミキュライトなどの軽量で保水性に富む無機性多孔質体を用いた 人工土壌も提案されるに至っているが、この土壌の場合には、山砂などの天然土 材に比べてｐＨが弱アルカリ性ないし中性であり、植物根の伸長に最適な土壌物 理条件を保てないという不具合があった。 本考案は、このような事情に鑑みなされたものであり、軽量であり、屋上等に 投入して盛土した場合でも、建築基準法上に定められた建築物への載荷荷重の制 限をクリアすることができ、しかも高い保水性及び通気性と豊富な肥料成分を有 する人工組合せ土壌をブロック状の袋体に詰め込んで成形したブロック状土壌を 提供することを目的とするものである。In recent years, as global environmental protection has been called for, forests play an important role in the conservation of biodiversity, especially as an absorption source of carbon dioxide, which is the source of global warming. Promotion of measures for forest sinks is being considered as an important issue. As measures to absorb forests, while promoting the conservation and development of forests in Okuyama and Satoyama, urban greening and reforestation around the cities are being implemented. In particular, when focusing on urban greening, specific examples include tree planting on roadsides, medians or parks, rooftops of buildings, balconies, balconies, etc. Tree planting on the rooftop, veranda, balcony, etc. of buildings (hereinafter referred to as rooftop greening) not only plays a role as a forest absorption source measure, but also has the effect of heat insulation inside and outside the building, air purification, and improving the aesthetics of the building. It can be expected, and rooftop greening can be implemented not only by national and local governments but also by private companies and ordinary households. Under these circumstances, rooftop greening is being implemented, but there are various obstacles to its implementation, and it is not widespread yet. For example, when a tree is planted on the roof of a building, a veranda, a balcony, etc. to carry out greening on the roof, there is a limit set by the Building Standard Law that the load on the building should not exceed 180 kg / m 2 . However, conventionally, when natural soil material such as mountain sand was put on the rooftop and the like and the soil was planted, the natural gravity of natural sand material such as mountain sand was large. The construction could not be done by itself. On the other hand, when the embankment was made smaller in consideration of the limitation of the loading load, the types of plants that could be planted such as shallow root tree species and shrubs were limited. Therefore, artificial soil using lightweight and highly water-retaining inorganic porous material such as vermiculite has also been proposed, but this soil has a weaker pH than natural soil materials such as mountain sand. Since it is alkaline or neutral, there is a problem that it is not possible to maintain the optimum soil physical conditions for plant root elongation. The present invention has been made in view of the above circumstances, is lightweight, and even when it is thrown into a rooftop or the like to embank, it clears the limit of the load applied to a building specified in the Building Standards Act. It is an object of the present invention to provide a block-shaped soil obtained by packing a synthetic bag-like soil having high water retention and air permeability and abundant fertilizer components into a block-shaped bag body, and molding .
上記目的を達成するため、本考案は、天然土材と木材チップと無機多孔質体の 物品の組合せからなり、前記天然土材と木材チップと無機多孔質体が、容積比で １：２：２〜１：２：３の割合で組み合わされており、比重が０．７〜０．９で あることを特徴とする人工組合せ土壌を両端に耳部を有するブロック状の袋体に 詰め込んで成形したことを特徴とするブロック状土壌を その要旨とした。 本考案のブロック状土壌における人工組合せ土壌において、天然土材としては 、真砂土または黒ボク土のいずれか１種を好ましい例として挙げることができる 。これらの天然土材には植物の生育に必要な肥料成分が豊富に含まれており、特 に黒ボク土は、赤黄色土などの他の天然土材に比べて比重が軽いという利点があ り、真砂土については安価であるという利点がある。また、本考案の天然土材と しては、前記真砂土と黒ボク土の混和物という形態で用いることもできる。 木材チップは、該人工組合せ土壌に有機質分を付与する成分である。木材チッ プとしては、樹木の枝や幹をチップ状に破砕した木質チップ、樹皮チップ、樹皮 付き木質チップなどが挙げられる。好ましくは剪定時に生じる木屑や朽ち木や枯 れ木（廃材）をチップ状に破砕した破砕物である。木材チップの大きさとしては 、直径が８．０〜１０．０ｍｍであって、長さが８．０〜１０．０ｍｍの大きさ に破砕したものが望ましい。木材チップの大きさは基本的には自由であるが、直 径及び長さを上記範囲とした場合には、取り扱い性が良好となるというメリット がある。 木材チップとして木屑の破砕物を用いる場合、木屑の破砕物をそのまま他の成 分と配合しても良いが、発酵した木屑の破砕物を用いることもできる。発酵した 木屑の破砕物としては、自然発酵したものの他に、例えば鶏糞や油かすなどの窒 素源を加えて好気性発酵させるなど従来公知の発酵方法により発酵処理したもの も使用できる。発酵処理した木屑の破砕物を用いた場合、発酵処理に使用する窒 素源がそのまま窒素肥料成分として破砕物中に残存するという利点がある。 尚、発酵の程度としては、木屑の破砕物がその原形を留める程度にしたものが 望ましい。また、発酵した木屑の破砕物を用いる場合、これに乾留処理を行って 、破砕物中の水分及びタール分を除去することで、該木屑の破砕物の軽量化を計 ることもできる。 無機多孔質体としては、パーライトまたはバーミキュライトのいずれか、また はこれらの混和物が好ましい。パーライトとしては、真珠岩を８００〜１０００ ℃で焼成発泡させたものや、黒曜石を８００〜１０００℃で焼成発泡させたもの であって、比重が０．２５〜０．５のものが好ましい。このパーライトは高温処 理のため、無毒、無臭、無菌であり、このパーライトを含ませることで、該人工 組合せ土壌に優れた保水性と通気性が付与されることになる。 バーミキュライトは、片磨岩や結晶片岩等の中に含まれる蛭石を８００〜１０ ００℃の高熱で焼成加工し、薄片の層の間にある微量の結晶水・構造水を水蒸気 として膨張させた多孔質体であり、その比重は０．１〜０．５のものが好ましい 。 このバーミキュライトは高熱処理により製造されているため、有害な菌や雑草 の種子を含まず、多孔質のため吸水力が極めて強く、空気の流通を良好とし、肥 料成分であるカリを含有し、窒素の吸着性をも持っている。 上記パーライト及びバーミキュライトは、Ｎａ，Ｋ，Ｃａ，Ｍｇ等の塩基性陽 イオンを吸着し易く（ＣＥＣ値が高い）、かつ、ＮＨ4 イオンを保持して、Ｎ， Ｐ，Ｋ等の肥効率も向上させると共にＮＨ3 ガスの揮散を抑制する性質を持つ。 本考案のブロック状土壌における人工組合せ土壌は、上記天然土材と木材チッ プと無機多孔質体が、容積比で１：２：２〜１：２：３の割合で組み合わされ、 その比重が０．７〜０．９となっている。上記範囲よりも天然土材量が多い場合 、該人工組合せ土壌の比重が大きくなり、少ない場合には植物の生育に適切な土 壌物理条件や最適ｐＨが保持できなくなる。 一方、木材チップ量が上記範囲よりも多い場合には、該人工組合せ土壌の軽量 化は進むが、保水性が低下し、ＣＥＣ値も小さくなるというデメリットがある。 また木材チップ量が上記範囲よりも少ない場合には有機質分が少なくなる。また 、無機多孔質体量が上記範囲よりも多い場合、保水性が高くなり、ＣＥＣ値も高 くなる反面、軽量化に伴う飛散の恐れや、植物の生育に必要な土壌物理条件が保 持できなくなる。 本考案のブロック状土壌における人工組合せ土壌は、ＣＥＣが５．０〜６．０ ｍｅ／１００ｇの範囲となっている。前述の如くその範囲は、天然土材と木材チ ップと無機多孔質体の物品の組合せの割合で決まる。ＣＥＣ値を５．０〜６．０ ｍｅ／１００ｇの範囲とすることで、植物の生育に必要な肥料成分が確保される ことになる。 本考案のブロック状土壌における人工組合せ土壌は、比重が０．７〜０．９で あることから、例えば建築物の屋上、ベランダ、バルコニー等に投入される屋上 植栽用土壌として好適な土壌である。またこの人工組合せ土壌は、橋やダムなど の土木構造物に造成される道路脇などに植樹するときに用いることもできる。ま た、大型客船や洋上フロート上へ植樹する際にも、植栽用土壌として適用するこ とができる。 本考案のブロック状土壌は、上記人工組合せ土壌が両端に耳部を有するブロッ ク状の袋体に詰め込まれて成形されていて、 ブロックとして取り扱うことができ 、運搬など取り扱い性が頗る良い。例えば図２０に示すように、両端に耳部を有 するブロック状の プラスチック製の袋体２０に天然土材と木材チップと無機多孔 質体の物品を組合せた人工組合せ土壌１０を詰め込んで成形することができる。 図２１に示すものは、両端の耳部に取っ手孔２１を設けたブロック状の袋体２ ０内に人工組合せ土壌１０を詰め込んで、人工組合せ土壌１０をブロック状に成 形したものである。この形態の場合、人工組合せ土壌１０は袋体２０の取っ手２ １を掴んで持ち運びができ、取り扱い性がさらによい。 図２２に示すものは、中央に袋の表裏に貫通する孔２２を設けたブロック状袋 体２０内に人工組合せ土壌１０を詰め込んで、人工組合せ土壌１０を中央に貫通 孔１１を有するブロック状に成形したものである。この形態の場合、運搬時や取 り扱い時にはこの孔１１または２１に手をかけて取り扱うことができ、より便利 である。また、この形態の場合には、人工組合せ土壌１０は袋体２０と共に中央 に貫通孔１１を有するブロック状に成形されるので、保管時には袋体２０の孔２ ２を合わせて多数上下に積み重ね、連通した孔に棒体を挿入するなどすることで 、荷崩れを防止することができるというメリットがある。To achieve the above object, the present invention comprises a combination of natural soil material, wood chips and an inorganic porous material, wherein the natural soil material, the wood chips and the inorganic porous material are in a volume ratio of 1: 2 :. It is combined at a ratio of 2 to 1: 2: 3 and has a specific gravity of 0.7 to 0.9. It is formed by packing artificial synthetic soil in a block-shaped bag having ears at both ends. The feature is the block-shaped soil which is characterized by the above. In the artificial soil combination of the block-shaped soil of the present invention , as the natural soil material, one of sand sand soil and black soil can be mentioned as a preferable example. These natural soil materials contain abundant fertilizer components necessary for plant growth, and in particular, Kuroboku soil has the advantage that its specific gravity is lighter than other natural soil materials such as red-yellow soil, There is an advantage that it is cheap for Masago soil. In addition, the natural soil material of the present invention can be used in the form of a mixture of the above-mentioned sand sand soil and Kuroboku soil. Wood chips are components that impart organic matter to the artificial combined soil. Examples of the wood chips include wood chips obtained by crushing the branches and trunks of trees into chips, bark chips, and wood chips with bark. Preferably, it is a crushed product obtained by crushing wood chips, decayed wood, or dead wood (waste wood) generated during pruning into chips. As the size of the wood chips, it is desirable that the wood chips have a diameter of 8.0 to 10.0 mm and a length of 8.0 to 10.0 mm. The size of the wood chips is basically free, but when the diameter and the length are within the above ranges, there is an advantage that the handleability becomes good. When the crushed wood chips are used as the wood chips, the crushed wood chips may be blended with other components as they are, but the crushed wood chips may also be used. As the crushed material of fermented wood chips, in addition to naturally fermented materials, those fermented by a conventionally known fermentation method such as aerobic fermentation by adding a nitrogen source such as chicken manure or oil dregs can also be used. When the crushed material of the wood chips subjected to the fermentation treatment is used, there is an advantage that the nitrogen source used for the fermentation treatment remains as it is as a nitrogen fertilizer component in the crushed material. It is desirable that the degree of fermentation is such that the crushed wood waste retains its original shape. Further, when a crushed product of fermented wood chips is used, it is possible to reduce the weight of the crushed product of wood chips by subjecting the crushed product to dry distillation to remove water and tar content in the crushed product. As the inorganic porous material, either perlite or vermiculite, or a mixture thereof is preferable. As pearlite, pearlite fired and foamed at 800 to 1000 ° C. or obsidian fired and foamed at 800 to 1000 ° C. and specific gravity of 0.25 to 0.5 are preferable. This perlite is non-toxic, odorless, and aseptic because it is treated at high temperature, and the inclusion of this perlite imparts excellent water retention and air permeability to the artificial combined soil. Vermiculite was obtained by calcining vermiculite contained in schist or crystal schist at high heat of 800 to 1000 ° C., and expanding a small amount of crystallization water / structured water between thin flakes as water vapor. A porous body having a specific gravity of 0.1 to 0.5 is preferable. Since this vermiculite is produced by high heat treatment, it does not contain harmful fungi or weed seeds, has a very strong water absorption due to its porous property, makes air circulation good, contains potassium as a fertilizer component, and contains nitrogen. It also has the adsorptivity of. The above-mentioned perlite and vermiculite easily adsorb basic cations such as Na, K, Ca, and Mg (high CEC value), and retain NH4 ions to improve fertilization efficiency of N, P, K, etc. It also has the property of suppressing the volatilization of NH3 gas. The artificial soil combination of the block soil of the present invention is a combination of the natural soil material, the wood chips and the inorganic porous material in a volume ratio of 1: 2: 2 to 1: 2: 3, and the specific gravity is 0. It is 7 to 0.9. When the amount of natural soil material is larger than the above range, the specific gravity of the artificial combined soil becomes large, and when the amount is small, it becomes impossible to maintain the soil physical conditions and optimum pH suitable for plant growth. On the other hand, when the amount of wood chips is larger than the above range, there is a demerit that although the weight of the artificial combined soil is reduced, the water retention is lowered and the CEC value is also reduced. When the amount of wood chips is less than the above range, the organic matter content is small. Further, when the amount of the inorganic porous material is larger than the above range, the water retention becomes high and the CEC value becomes high, but on the other hand, there is a fear of scattering due to weight reduction, and it becomes impossible to maintain the soil physical conditions necessary for plant growth. . The artificial soil combination of the block soil of the present invention has a CEC in the range of 5.0 to 6.0 me / 100 g. As described above, the range is determined by the ratio of the combination of the natural soil material, the wood chips, and the inorganic porous article. By setting the CEC value in the range of 5.0 to 6.0 me / 100 g, the fertilizer components necessary for plant growth can be secured. Since the artificial soil in the block-shaped soil of the present invention has a specific gravity of 0.7 to 0.9, it is suitable as a soil for rooftop planting that is put on, for example, the rooftop of a building, a balcony, or a balcony. is there. Further, this artificial combined soil can also be used when planting trees on the side of a road formed in a civil engineering structure such as a bridge or a dam. It can also be used as planting soil when planting trees on large passenger ships and offshore floats. Blocky soil of the present invention, said artificial combination soil have been molded packed block-type body having ears at both ends, can be handled as a block, handling properties such as transportation is extremely good. For example, as shown in FIG. 20, forming packed artificial combination soil 10 that combines the articles of natural soil material and the wood chips and the inorganic porous material in a block-shaped plastic bag 20 to have the ears at both ends be able to. In FIG. 21, the artificial combined soil 10 is packed in a block-shaped bag body 20 having handle holes 21 at both ends to form the artificial combined soil 10 in a block shape. In the case of this form, the artificial combined soil 10 can be carried by grasping the handle 21 of the bag body 20, and the handleability is further improved. As shown in FIG. 22, the artificial combined soil 10 is packed in a block-shaped bag body 20 having a hole 22 penetrating the front and back of the bag in the center, and the artificial combined soil 10 is formed into a block shape having a through hole 11 in the center. It is molded. In the case of this form, the hole 11 or 21 can be handled by hand during transportation or handling, which is more convenient. In addition, in the case of this embodiment, the artificial combined soil 10 is formed into a block shape having the through hole 11 in the center together with the bag body 20, so that a large number of holes 22 of the bag body 20 are piled up and down in a stack during storage. There is an advantage that it is possible to prevent the load from collapsing by inserting a rod into the communicating hole.
以下、本考案のブロック状土壌における人工組合せ土壌の好ましい実施例を示 す。図１は、本考案の人工組合せ土壌を用いてビルの屋上に造成された屋上庭園 を示し、この庭園１には様々な種類の高木２、中木３、及び低木４が植栽されて いる。 屋外実験１ 表１に示す３種類の土壌に関し、植物生育への影響を調べた。その結果を表３ 並びに図２〜図６に示した。 表１ （容積比） 表１中、木材チップは、剪定後に樹木の幹、枝を長さ８〜１０ｍｍに寸断した ものを用いた。また、パーライトとしては、日本セメント株式会社製のアサノパ ーライト（Ｐ−３）を用い、真砂土としては、岡田建材株式会社製の細粒分混礫 質砂（土性分類ＳＧ−Ｆ）を用いた。 尚、表１中の実施例１の比重並びにＣＥＣを測定したところ、比重は０．８８ 、ＣＥＣは５．４me/100gであった。 実験は、まず、ヨコ１２０ｃｍ×タテ９０ｃｍ×深さ８０ｃｍのコンテナの底 １５ｃｍに砂利を敷き、この上に上記実施例１、比較例１及び２の各土壌を投入 するとともに、下記表２に示すレッドロビン、サツキツツジ、ボックスウッド、 ゴールドクレスト、ヒペリカムカリシナムの５樹種の植物をそれぞれの鉢に植樹 し、２ヶ月間生育させて、実験開始前と実験終了後における各土壌に植樹した植 物の生育状態、具体的には 樹高、葉張及び根鉢の大きさ（高さm×幅m）を測定 した。その結果を表３並びに図２〜図６に示した。尚、実験に使用した植物には 、いずれも３年生の苗を用いた。 表２ 表３ 表３並びに図２〜図６から、木材チップとパーライトのみからなる比較例１は 、真砂土のみからなる比較例２と同等、若しくはやや劣る結果となった。これに 対し、実施例１のものは、いずれも比較例１及び２以上の生育結果が確認された 。特にレッドロビンやゴールドクレスト等の中高木種については、比較例１及び ２の樹高がいずれも約１１２％（実験終了時の樹高／実験開始時の樹高）である のに対し、実施例１の樹高は約１３０％と高い成長率が確認された。 また、通常、樹木の移植に際し、堀り上げられる根系を含んだ土のまとまりを 示す根鉢の大きさについても、比較例１及び２と比べて実施例１のものは大きく 、実施例１の土壌が根の成長に有効であることが確認された。 屋内実験 底面の直径が１５ｃｍ、開口の直径が２１ｃｍ、深さが２１ｃｍの円柱状ポッ トを用い、このポット内に砂利を敷き、この上に上述の実施例１及び比較例２、 さらにパーライトのみからなる比較例３の土壌を加えた３種類の土壌３６００ｃ ｍ3を投入した。 そして、それぞれのポットに、下記表６に示すキンマサキ、パイナップルミン ト、レッドロビンの３樹種の植物を植樹し、３ヶ月間生育させて、各土壌に植樹 した植物の伸長率（伸長量／初期樹高）と根の伸長状態（根の伸長ｃｍ）を測定 した。その結果を図８〜図１３、並びに図１４〜図１９に示した。尚、実験に使 用した植物には、いずれも３年生の苗を用いた。本実験は図７に示すように、気 候に左右されにくいハウス内で実験した。 図８〜図１３から、実施例１の土壌は、比較例２及び３に劣らない植物に高い 成長率をもたらす土壌であることが確認された。 また本実験の各実施例１、並びに比較例２及び３では、施肥を行ったもの（図 ８、図１０、図１２）と施肥を行っていないもの（図９、図１１、図１３）につ いても対比し、各例における植物の生育状態を観察した。 この結果から、施肥を行った植物、特には図１０に示すパイナップルミントの 例において、ＣＥＣ値が大きな比較例３よりも実施例１の土壌で成長がよく、こ れにより、該実施例１の土壌が、根の伸長により適した土壌物理条件を保持して いることが確認された。 また、上記屋内実験で生育した各植物について、根の状態を観察したところ、 図１４〜図１９に示すとおり、実施例１の土壌で育てたものが最も根の伸張がよ いことが確認された。この結果から、有機質分を有する木材チップとＣＥＣの高 いパーライトを含む実施例１の土壌は、施肥の有無によらず、樹木を安定的に生 育させることができると考えられる。Hereinafter, a preferred embodiment of the artificial combination soil in the block soil of the present invention will be shown. FIG. 1 shows a rooftop garden constructed on the rooftop of a building using the artificial soil mix of the present invention, in which various types of trees 2, 3 and 4 are planted. . Outdoor Experiment 1 With respect to the three types of soils shown in Table 1, the effects on plant growth were examined. The results are shown in Table 3 and FIGS. Table 1 (volume ratio) In Table 1, as the wood chips, tree trunks and branches were cut into pieces each having a length of 8 to 10 mm after pruning. As perlite, Asano perlite (P-3) manufactured by Nippon Cement Co., Ltd. is used, and as sand sand, fine-grained gravel sand (soil classification SG-F) manufactured by Okada Kenzai Co., Ltd. is used. I was there. When the specific gravity and CEC of Example 1 in Table 1 were measured, the specific gravity was 0.88 and the CEC was 5.4 me / 100 g. In the experiment, first, gravel is laid on the bottom 15 cm of a container of 120 cm in width × 90 cm in length × 80 cm in depth, and the soils of Example 1 and Comparative Examples 1 and 2 are put on the container, and the results are shown in Table 2 below. Plants of 5 tree species, Red Robin, Satsuki Azalea, Boxwood, Goldcrest, and Hypericum calicinum, were planted in their respective pots and allowed to grow for 2 months, and then planted in each soil before and after the experiment. The state, specifically, the tree height, the leaf tension, and the size of the root pot (height m × width m) were measured. The results are shown in Table 3 and FIGS. As the plants used in the experiment, seedlings of the 3rd grade were used. Table 2 Table 3 From Table 3 and FIGS. 2 to 6, Comparative Example 1 including only wood chips and perlite resulted in a result equal to or slightly inferior to Comparative Example 2 including only sand sand. On the other hand, in the case of Example 1, the growth results of Comparative Examples 1 and 2 or more were confirmed. In particular, for medium- and high-tree species such as red robin and gold crest, the tree heights of Comparative Examples 1 and 2 were both about 112% (tree height at the end of the experiment / tree height at the start of the experiment), while A high growth rate was confirmed with a tree height of about 130%. In addition, normally, in the case of transplanting trees, the size of the root pot showing the mass of soil including the root system dug up is larger in Example 1 than in Comparative Examples 1 and 2, and It was confirmed that the soil was effective for root growth. Indoor experiment A cylindrical pot having a bottom diameter of 15 cm, an opening diameter of 21 cm, and a depth of 21 cm was used, gravel was laid in the pot, and the above-mentioned Example 1 and Comparative Example 2 were used, and only perlite was used. Then, 3600 cm 3 of three types of soil including the soil of Comparative Example 3 were added. Then, in each pot, plants of tree species of Kimasaki, pineapple mint, and red robin shown in Table 6 below were planted, allowed to grow for 3 months, and the elongation rate (extension amount / initial tree height) of the planted plant in each soil. ) And the extension state of the root (extension cm of the root) were measured. The results are shown in FIGS. 8 to 13 and 14 to 19. As the plants used in the experiment, seedlings of the 3rd grade were used. As shown in FIG. 7, this experiment was conducted in a house that is not easily affected by climate. From FIG. 8 to FIG. 13, it was confirmed that the soil of Example 1 is a soil that brings a high growth rate to plants that are not inferior to Comparative Examples 2 and 3. In addition, in each Example 1 and Comparative Examples 2 and 3 of this experiment, the fertilizer applied (FIG. 8, FIG. 10, FIG. 12) and the fertilizer not applied (FIG. 9, FIG. 11, FIG. 13) The growth state of the plant in each case was also observed in comparison. From these results, in the fertilized plants, particularly in the example of pineapple mint shown in FIG. 10, the soil of Example 1 grew better than the soil of Comparative Example 3 having a large CEC value, whereby the soil of Example 1 was obtained. However, it was confirmed that the soil had more suitable soil physical conditions due to root elongation. Moreover, when the root condition of each plant grown in the indoor experiment was observed, it was confirmed that the root growth was best in the plant grown in the soil of Example 1, as shown in FIGS. 14 to 19. . From this result, it is considered that the soil of Example 1 containing wood chips having organic matter and perlite having a high CEC can stably grow trees regardless of the presence or absence of fertilization.
