墓地や公園や中央分離帯などにおける雑草の繁殖は除去に人手を要し、作業は多労働で経費がかかる問題がある。そこで除草剤が使用されるが、除草剤は特に環境に対して種々の薬害の原因となるので安心して使用できない問題がある。   The breeding of weeds in cemeteries, parks and median strips requires manual labor to remove them, and the work is labor intensive and expensive. Therefore, herbicides are used. However, herbicides cause various phytotoxicity especially to the environment, so there is a problem that they cannot be used with confidence.

酸化マグネシウムと増量材を含み酸化マグネシウムが水と反応して硬化するようにして地面に硬化層を形成して雑草の繁殖を防止する雑草繁殖防止材(特許文献1参照)が提案されているが、酸化マグネシウムは水溶性であり雨水によって溶解して散逸してしまい、効果の持続性に問題があるとともに、酸化マグネシウムおよびその水溶液はアルカリ性が高く人や環境に対して悪影響を及ぼす恐れがある他に、硬化層が冬場に凍ってヒビ割れが発生し雑草が繁茂する問題がある。又、緑石、巻き石など時間経過と共に、膨張収縮率の違いにより、隙間が出来てそこに雑草が繁茂する問題がある。   A weed growth prevention material (see Patent Document 1) that includes magnesium oxide and an extender and prevents the growth of weeds by forming a hardened layer on the ground so that the magnesium oxide reacts with water and hardens is proposed. Magnesium oxide is water-soluble and dissolves and dissipates due to rainwater, and there is a problem with the sustainability of the effect. Magnesium oxide and its aqueous solution are highly alkaline and may adversely affect people and the environment. In addition, the hardened layer freezes in the winter and cracks occur and weeds grow. In addition, there is a problem that weeds grow over there due to differences in expansion and contraction rates with time, such as green stones and rolling stones.

真砂土、砂、セメントや石灰などの粉体固化材を含む舗装材を敷設してローラなどで転圧し、転圧した舗装面に散水しローラなどで転圧して固化して舗装道とする自然舗装道用舗装材(特許文献2参照)が提案されているが、苔やかびの発生を防止できず、苔やかびが発生すれば外観が悪くなる他に、冬場に凍ってヒビ割れが発生し雑草が繁茂する問題もある。又、緑石、巻き石など時間経過と共に、膨張収縮率の違いにより、隙間が出来てそこに雑草が繁茂する問題がある。
表面で光を反射させて視認性を高めるための貝殻粉粒体と硬化させるためのセメントを含む硬化材を地面に敷き散水してセメントを硬化させて通水性除草舗装で被覆して道路の緑地帯に雑草が生えるのを防止する表面処理方法(特許文献3参照)が提案されているが、苔やかびの発生を防止できず、苔やかびが発生すれば外観が悪くなる他に、冬場に凍ってヒビ割れが発生し雑草が繁茂する問題もある。又、緑石、巻き石など時間経過と共に、膨張収縮率の違いにより、隙間が出来てそこに雑草が繁茂する問題がある。

表1から本発明の防草材および防草固化材は施工性および防草、防苔、防かび効果に優れていることが判る。それに対して、コレマナイトを配合していない比較例1は防草効果に劣り、コレマナイトを配合しているが難溶性アルミニウム化合物粉粒体(蝋石)を用いず珪砂を用いた比較例2は施工性および防草効果に劣り、難水溶性アルミニウム化合物粉粒体(蝋石)を配合しているが難水溶性硼素化合物粉粒体(コレマナイト)を用いず水溶性の硼砂を用いた比較例3は硼素の溶出がおおきく溶出試験後の硼素濃度が高く×と評価され、消石灰を用いた比較例4は6ケ月後の防草効果に劣り、コレマナイトを配合していない固化タイプの比較例5は防草、防苔、防かび効果に劣り、草刈りを行っただけの比較例6は防草効果に劣ることが判る。   It can be seen from Table 1 that the herbicidal material and the herbicidal solidifying material of the present invention are excellent in workability and the herbicidal, mossy and fungicidal effects. In contrast, Comparative Example 1 containing no colemanite is inferior in herbicidal effect and contains colemanite, but comparative example 2 using silica sand without using a hardly soluble aluminum compound granule (waxite) is workability. In Comparative Example 3, which was inferior in herbicidal effect and contained poorly water-soluble aluminum compound granules (waxite) but did not use poorly water-soluble boron compound granules (Colemanite), but used water-soluble borax. The comparative example 4 using slaked lime is inferior in herbicidal effect after 6 months, and the solidified type comparative example 5 containing no colemanite is herbicidal. It can be seen that Comparative Example 6, which is poor in moss-proofing and anti-fungal effects and only mowing, is inferior in the herbicidal effect.

本発明の防草材や防草固化材は、粉粒体の状態で地面に容易に施工することができ、風が吹いても粉塵が発生し難く、冬場に凍ってヒビ割れが発生することがなく、しかも難溶性硼素化合物粉粒体と難溶性アルミニウム化合物粉粒体とは難溶性であるので防草有効成分を徐放することができ、例えばアルミニウムが徐放されると土壌中のリン酸を不溶化するので植物に重要な養分を欠乏させることができ、また硼素が徐放されると防草効果がおおきいので、雑草の生育を防止するとともに、苔やかびの発生を防止でき、効果の持続性に優れるので、墓地や霊園の防草、公園や中央分離帯やガーデンアプローチや犬走りの防草、鉄塔下、高架下、交差点、路側帯の防草などに有効に使用することができる上、安価で環境に対して優しいという顕著な効果を奏し、
本発明の防草材の施工方法により、墓地や霊園、公園や中央分離帯やガーデンアプローチや犬走り、鉄塔下、高架下、交差点、路側帯などの地面に容易に施工することができるなどの顕著な効果を奏するので、産業上の利用価値が高い。
The herbicidal material and the herbicidal solidifying material of the present invention can be easily applied to the ground in the form of a granular material, dust is hardly generated even if the wind blows, and it is frozen in the winter and cracks occur. In addition, since the hardly soluble boron compound particles and the hardly soluble aluminum compound particles are hardly soluble, the herbicidal active ingredient can be released slowly. For example, when aluminum is released slowly, phosphorus in the soil Since it makes the acid insoluble, it can deplete important nutrients in the plant, and when the boron is released slowly, the herbicidal effect is great, thus preventing the growth of weeds and preventing the occurrence of moss and mold. Because it has excellent sustainability, it can be used effectively for cemetery and cemetery weeds, parks and median strips, garden approaches and dog-running weeds, under steel towers, underpasses, intersections, and roadside weeds. It can be made cheap and environmentally friendly Exhibit the effect,
The construction method of the herbicidal material of the present invention can be easily constructed on the ground such as a cemetery, a cemetery, a park, a median strip, a garden approach, a dog run, a steel tower, an underpass, an intersection, a roadside belt, etc. Since it has a remarkable effect, it has high industrial utility value.
