以下に、客土層６に配合される腐朽チップの製造方法について説明する。
まず、剪定材等の木材を直径４〜１５ｍｍ、長さ３０〜１００ｍｍのチップ状となるように破砕する。
破砕して得られた木材チップを幅５ｍ、長さ１０ｍ、高さ２ｍの小山状に堆積させる。この小山にした木材チップ１００質量部に対し、水分調整剤としての米ぬかを１０〜３５質量部、分解促進剤としての窒素肥料を１０〜３５質量部の割合で混合するのが好ましく、米ぬかを１５〜２０質量部、窒素肥料を１５〜２０質量部混合するのがさらに好ましい。窒素肥料としては石灰窒素を用いるのが好ましく、目標ＣＮ比を３０とする。
ここで、米ぬかの割合が１０質量部未満であり、窒素肥料の割合が１０質量部未満である場合、短期間に腐朽チップを得ることが出来ない。また、米ぬかの割合が３５質量部を超え、窒素肥料の割合が３０質量部を超える場合、発酵が進みすぎ、良好な保水性を有する腐朽チップが得られない。 Below, the manufacturing method of the decayed chip | tip mix | blended with the customer soil layer 6 is demonstrated.
First, a wood such as a pruning material is crushed so as to have a chip shape with a diameter of 4 to 15 mm and a length of 30 to 100 mm.
The wood chips obtained by crushing are deposited in a small mountain shape having a width of 5 m, a length of 10 m, and a height of 2 m. It is preferable to mix 10 to 35 parts by mass of rice bran as a moisture adjusting agent and 10 to 35 parts by mass of nitrogen fertilizer as a decomposition accelerator with respect to 100 parts by mass of the wood chips made into a small mountain. More preferably, -20 parts by mass and 15-20 parts by mass of nitrogen fertilizer are mixed. Lime nitrogen is preferably used as the nitrogen fertilizer, and the target CN ratio is 30.
Here, when the ratio of rice bran is less than 10 parts by mass and the ratio of nitrogen fertilizer is less than 10 parts by mass, it is not possible to obtain decayed chips in a short time. Moreover, when the ratio of rice bran exceeds 35 mass parts and the ratio of nitrogen fertilizer exceeds 30 mass parts, fermentation progresses too much and the decayed chip | tip which has favorable water retention cannot be obtained.

この混合に用いる木材チップは乾燥過多のものは使用しない。使用する場合は、湿潤状態の木材チップと混合して使用する。木材チップの水分は５０〜５５％位に調整するのが好ましい。乾燥した木材チップを用いた場合、発酵促進剤の機能低下が起こり、腐朽期間にバラツキが生じたり、発酵不良による腐敗菌の繁殖を誘発して発酵障害が生じる。水分が多い場合、嫌気性細菌が増えて腐る可能性がある。   Wood chips used for this mixing should not be overdried. When used, it is used by mixing with wet wood chips. The moisture of the wood chip is preferably adjusted to about 50 to 55%. When dry wood chips are used, the function of the fermentation promoter is reduced, causing variations during the decay period, or causing the growth of spoilage bacteria due to poor fermentation, resulting in fermentation failure. When there is a lot of water, anaerobic bacteria increase and it may rot.

発酵期間中は酸素を十分与えることが必要であるが、微生物の分解に伴う発酵熱を備蓄するため、空気を適度に遮断する必要がある。従って、５〜７日に一度の割合で、空気を入れるためにかき回すのが好ましい。   It is necessary to supply oxygen sufficiently during the fermentation period, but it is necessary to appropriately shut off air in order to store the heat of fermentation accompanying the decomposition of microorganisms. Therefore, it is preferable to stir to inject air once every 5 to 7 days.

発酵菌が繁殖するとき、熱が生じる。このとき温度は６０〜７０度程度になり、病原菌及び寄生虫の卵、雑草の種子等が死滅する。このように温度が上昇しない場合、「うじ」等が発生する。
発酵熱を生じさせるためには、適度に材料が多い必要がある。材料が少ない場合、周囲から熱が奪われ、中心の温度が下がる。発酵菌を効率よく増殖させるためには、必要に応じて米ぬか、窒素等を追加して混合する。
熱が上昇した時点で、材料をかき回す、「切り返し」を行う。これにより、酸素の供給と水分の調節とがなされて発酵分解が促進し、材料が均一化する。「切り返し」を行った後、急激な熱の上昇がない場合、腐朽が完成したことになる。 When fermenting bacteria propagate, heat is generated. At this time, the temperature is about 60 to 70 ° C., and pathogens and parasite eggs, weed seeds and the like are killed. If the temperature does not rise in this way, “flying” or the like occurs.
In order to generate fermentation heat, it is necessary to have a moderate amount of materials. When there is little material, heat is taken away from the surroundings, and the temperature of the center decreases. In order to efficiently proliferate the fermenting bacteria, rice bran, nitrogen or the like is added and mixed as necessary.
When the heat rises, the material is stirred and “turned back” is performed. Thereby, supply of oxygen and adjustment of moisture are performed, fermentation decomposition is promoted, and the material becomes uniform. If there is no sudden rise in heat after “turning back”, then the decay is complete.

１４日以上の処理日数を経た本実施の形態の木材チップは、従来の牛糞・おが屑堆肥と同程度の発芽・生育状態を示す。   The wood chip of the present embodiment that has been treated for 14 days or more shows a germination and growth state similar to that of conventional cow dung and sawdust compost.

石灰窒素の投入により木材チップ全体のＰＨは上昇するが、長期的に見た場合、石灰窒素の投入時よりＰＨは下がり、７日以降はＰＨも安定し、発酵状態が落ち着く。
この製造方法によれば、ＰＨが低く、ＣＮ比が高くなり、良好な発酵状態が保持されるので、従来と比較して短期間に腐朽チップが得られる。従って、道路の植え込み等で剪定された樹木を早急に処理して客土層６に用いることが出来るので、剪定樹木の有効利用が図られる。
そして、水分調整材として米ぬかを用いるので、客土層６の保水性が良好になり、客土層６の湿度が良好に保持され、水分調整材としておが屑を用いた場合と異なり、得られた腐朽チップを含む客土層に植えられた植物に発芽障害及び生育障害が生じず、植物が良好に成長する。従って、植物の管理も容易である。 Although the pH of the whole wood chip increases due to the introduction of lime nitrogen, when viewed over the long term, the PH is lower than when lime nitrogen is added, the pH is stabilized after 7 days, and the fermentation state is settled.
According to this production method, the PH is low, the CN ratio is high, and a good fermentation state is maintained, so that a decayed chip can be obtained in a short period of time compared to the conventional method. Therefore, since the tree pruned by road planting or the like can be quickly processed and used for the customer soil layer 6, effective use of the pruned tree is achieved.
And since rice bran is used as the moisture adjusting material, the water retention of the soil layer 6 is good, the humidity of the soil layer 6 is well maintained, and unlike the case where sawdust is used as the moisture adjusting material, it was obtained. The plant planted in the soil layer containing decayed chips does not cause germination and growth problems, and the plant grows well. Therefore, plant management is also easy.

上述したように、本実施の形態の雨水貯留システム１には、パレット４を備え、雨水貯留槽３の側面には補強リブ３２が設けられているので、荷重に対する強度が強く、客土層６をバランスよく支持することが出来る。
従って、防災ゾーン、各種公園・広場、住宅地の庭等の広範囲の領域に、雨水貯留型緑化装置１０を複数設置して雨水貯留システム１を構成した場合においても、強度的に問題がなく、また、地中に埋設して使用することも可能である。
そして、本実施の形態においては、雨水貯留槽３からパレット４を介し、蒸発又は湿度差により水分が客土層６へ供給されるので、客土層６に植えられた植物に必要な水分が自然に供給されるとともに、客土層６の湿度が一定に保持されるので、地表面の温度上昇も抑制することが出来る。従って、本発明の雨水貯留システム１は、地球温暖化対策にも適用され得る。 As described above, the rainwater storage system 1 according to the present embodiment includes the pallet 4 and the reinforcement ribs 32 are provided on the side surfaces of the rainwater storage tank 3. Can be supported in a balanced manner.
Therefore, even when the rainwater storage system 1 is configured by installing a plurality of rainwater storage type greening devices 10 in a wide area such as a disaster prevention zone, various parks / open spaces, and gardens in residential areas, there is no problem in strength. It is also possible to embed it in the ground.
And in this Embodiment, since water | moisture content is supplied to the customer soil layer 6 by the evaporation or a humidity difference from the rainwater storage tank 3 via the pallet 4, the water | moisture content required for the plant planted in the customer soil layer 6 is sufficient. While being supplied naturally, the humidity of the soil layer 6 is kept constant, the temperature rise of the ground surface can be suppressed. Therefore, the rainwater storage system 1 of the present invention can also be applied to global warming countermeasures.

本実施の形態においては、雨水貯留型緑化装置１０が複数連結して設置されており、降雨時には、客土層６を浸透した雨水が雨水貯留槽３に貯留されるので、特に強雨時には第２排水ホース１３からの排水を制御することで、河川等へ急激に雨水が流れ込むのを防止することが出来、水害が防止され得る。
そして、地震等の災害が生じた場合には、第２排水ホース１３からの排水を生活水として利用することが出来る。 In the present embodiment, a plurality of rainwater storage type greening devices 10 are connected and installed, and rainwater penetrating the soil layer 6 is stored in the rainwater storage tank 3 at the time of rain. 2 By controlling the drainage from the drainage hose 13, it is possible to prevent rainwater from abruptly flowing into rivers and the like, and flood damage can be prevented.
And when disasters, such as an earthquake, arise, the waste_water | drain from the 2nd drainage hose 13 can be utilized as domestic water.
