Description
本発明は、弱酸性乃至酸性である木質熱処理物に有用微生物を保持してなる緑化資材並びにその製造方法及び使用方法に関する。 The present invention relates to a greening material obtained by holding useful microorganisms in a slightly acidic or acidic woody heat-treated product, and a method for producing and using the same.
木炭、竹炭などの植物炭化物は、園芸及び農業分野では古くから利用されているが、有用微生物、特に外生菌根菌、ＶＡ菌根菌、エリコイド菌根菌などと組み合わせた利用例は数少なく、これらの有用微生物を作物の栽培に利用した代表的な例としては、ダイズの栽培に木炭とマメ科植物固有の根粒菌（リゾビウム(Rhizobium)属）を利用した栽培例がみられる（例えば、特許文献１参照。）。また、植物炭化物が土壌中における有用微生物の保持及び増殖に適切な素材であることは知られているが（例えば、特許文献２、特許文献３、非特許文献１及び非特許文献２など参照。）、微生物に応じた適切な特性を有する植物炭化物と上記の有用微生物とを組み合わせて、予め有用微生物を増殖させた製品については知られていない。すなわち、植物炭化物を有用微生物の保持ではなく、増殖のための素材として利用した例は見当たらない。 Plant charcoal such as charcoal and bamboo charcoal has been used for a long time in the horticulture and agriculture fields, but there are few examples of use in combination with useful microorganisms, especially ectomycorrhizal fungi, VA mycorrhizal fungi, ericoidal mycorrhizal fungi, Typical examples of the use of these useful microorganisms for cultivation of crops include the cultivation of soybeans using charcoal and legume-specific rhizobia (genus Rhizobium) (for example, patents). Reference 1). In addition, it is known that plant carbide is a material suitable for the retention and growth of useful microorganisms in soil (see, for example, Patent Document 2, Patent Document 3, Non-Patent Document 1, and Non-Patent Document 2). ), A product obtained by proliferating useful microorganisms in advance by combining plant charcoal having appropriate characteristics according to microorganisms and the above-mentioned useful microorganisms is not known. In other words, there is no example of using plant charcoal as a material for growth, not for holding useful microorganisms.
有用微生物の働きを利用した緑化資材及び園芸資材は既に開発され、商品化されているが（例えば、特許文献４、特許文献５及び特許文献６など参照。）、特に外生菌根菌やＶＡ菌根菌のような共生微生物を用いた共生微生物資材では、土壌に施用した場合、安定した効果が得られていない。これは、施用した土壌中にもともと存在する土壌微生物の影響や土壌そのものの特性によって、施用した共生微生物が十分に作用できる環境が整わないためである（例えば、非特許文献３など参照。）。すなわち、これらの共生微生物が土壌中で植物と共生関係を結ぶためには、ある程度以上の菌密度が必要であるが、土壌中では他の微生物の菌密度の方が遙かに高く、施用した有用微生物が上手く機能しないためである。 Greening materials and horticultural materials utilizing the action of useful microorganisms have already been developed and commercialized (see, for example, Patent Document 4, Patent Document 5, and Patent Document 6), but especially ectomycorrhizal fungi and VA. A symbiotic microorganism material using a symbiotic microorganism such as a mycorrhizal fungus does not provide a stable effect when applied to soil. This is because the environment in which the applied symbiotic microorganisms can sufficiently act is not prepared due to the influence of the soil microorganisms originally present in the applied soil and the characteristics of the soil itself (see, for example, Non-Patent Document 3). In other words, in order for these symbiotic microorganisms to establish a symbiotic relationship with plants in the soil, the density of bacteria above a certain level is necessary, but the density of other microorganisms in the soil is much higher, and it was applied. This is because useful microorganisms do not function well.
従来の緑化技術では、施工場所の土壌養水分条件が劣悪であったり、施工場所が急斜面である場合には、植物の生長が遅く、土壌も流亡しやすいため、植物の定着が難しく、そのような場所での植物の生育には肥料分の補給が不可欠であるが、緑化の場合には、特に施肥管理を行うことが難しく、園芸や造園の場合でも、その効果は長くても１年以内であった。また、肥料を大量に施用することは、雨水の流出により周辺水源の汚染にもつながるため、周囲の環境に対して負荷の少ない栽培管理方法が望まれている。さらに、施肥時に窒素成分が多いと雑草が繁茂するため、除草などの管理が必要以上に増えるばかりか、土壌中の硝化細菌などの土壌微生物相が攪乱され、生態系の早期回復も遅れる要因となる。また、窒素成分は、特に流亡し、分解されやすく、何らかの方法による継続的な補給が不可欠である。 With conventional tree planting technology, if the soil moisture condition at the construction site is poor or the construction site is a steep slope, the plant growth is slow and the soil is likely to be washed away. However, in the case of greening, it is difficult to manage fertilization, especially in the case of horticulture and landscaping. Met. Moreover, since applying fertilizer in large quantities also leads to contamination of surrounding water sources due to the outflow of rainwater, a cultivation management method with a low load on the surrounding environment is desired. Furthermore, weeds grow when there are many nitrogen components at the time of fertilization, which not only increases the management of weeding more than necessary, but also disturbs the soil microflora such as nitrifying bacteria in the soil and delays the early recovery of the ecosystem. Become. In addition, the nitrogen component is particularly easily washed away and decomposed, and it is indispensable to continuously replenish it by some method.
通常、植物炭化物は含まれる灰分によって化学的特性が弱アルカリ性〜アルカリ性となるため、有用微生物の中でも弱酸性〜酸性の条件を好む外生菌根菌、ＶＡ菌根菌、エリコイド菌根菌などの共生微生物にとって、増殖素材としての適性は低く、土壌中に植物炭化物を少量施用することにより、雨水によって中和されることにより、有用微生物の効果が得られることを期待して使用していたが、土壌中にもともと生息する土壌微生物の影響や土壌そのものの特性によって、安定した効果を得ることが難しかった。従って、外生菌根菌、ＶＡ菌根菌、エリコイド菌根菌などの共生微生物の増殖が容易な素材を見出し、これらの菌を高密度に保持した資材を作出することが緑化資材の開発にとっての課題であった。 Usually, plant charcoal has chemical properties that are weakly alkaline to alkaline depending on the ash contained in it. Therefore, among useful microorganisms, ectomycorrhizal fungi, VA mycorrhizal fungi, ericoidal mycorrhizal fungi that prefer weakly acidic to acidic conditions, etc. For symbiotic microorganisms, the suitability as a propagation material is low, and it was used with the expectation that the effects of useful microorganisms could be obtained by neutralizing with rainwater by applying a small amount of plant carbide to the soil. It was difficult to obtain a stable effect due to the influence of soil microorganisms originally inhabiting in the soil and the characteristics of the soil itself. Therefore, finding materials that allow easy growth of symbiotic microorganisms such as ectomycorrhizal fungi, VA mycorrhizal fungi, and ericoidal mycorrhizal fungi, and creating materials that retain these fungi at a high density is essential for the development of greening materials. It was an issue.
本発明者らは、上記課題を解決するために種々の検討を行った結果、弱酸性乃至酸性である炭化物すなわち木質熱処理物に共生微生物を高密度に保持することを見出し、本発明を提供するに至った。 As a result of various studies to solve the above-mentioned problems, the present inventors have found that symbiotic microorganisms are retained at a high density in a weakly acidic or acidic carbide, that is, a wood heat treatment, and provide the present invention.

Half the volume of PDB medium (Difco) is added to a wood heat-treated product (manufactured by Takeuchi Wood Industry Co., Ltd., Misono Nare TM ), and the temperature is 121 ° C., 11.8 × 10 4 Pa (1. High-pressure sterilization treatment was performed for 15 minutes under the condition of 2 kgf / cm 2 ). On the other hand, four colonies of Oidiodendron sp. Previously plated in PDA medium (manufactured by Difco) were cut into 5 mm squares and inoculated on the surface of the heat-treated wood containing PDB medium that had been sterilized. And cultured at 28 ° C. After culturing for about 1 month and the woody heat-treated product was sufficiently covered with black-gray mycelium, it was used as a greening material for retaining ericoidal mycorrhizal fungi. The results of measuring the bacterial cell content in the greening material are shown in FIG. On the other hand, as a comparative example, the ectomycorrhizal fungi wood Cook instead charcoal (Nara carbide Industry Co., Ltd. Green carbon TM) in place of the bacterial content and wood heat-treated product in the case of greening materials by using a FIG. 4 also shows the bacterial cell content when using Kanuma soil (manufactured by Toyo Horticulture) as a greening material. As a result, when the greening material is made using charcoal, the bacterial cells hardly grow, and the dry weight of the bacterial cells contained in the greening material is about 2 than when the greening material is made using Kanuma soil. It was confirmed that the increase was doubled.
