BIODEGRADABLE NONWOVEN FABRIC SHEET AND WEED-PROOF GREENING METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide a biodegradable nonwoven fabric sheet on which plant seeds and calcium aluminate-containing substance are sprayed, or water or an aqueous polymer emulsion liquid is added thereon, and provide a weed-proof greening method using the sheet to inhibit the growth of weeds.SOLUTION: A biodegradable nonwoven fabric sheet is formed by dispersion of plant seeds and a calcium aluminate-containing substance with a CaO/AlOmole ratio of 1.3 to 3.0 in an amount of 50 to 1000 g per 1 m. The biodegradable nonwoven fabric sheet is formed by spraying water or an aqueous polymer emulsion liquid from above. In the weed-greening method for inhibiting the growth of weeds by propagating dispersed plant seeds, the biodegradable nonwoven fabric sheet is placed on the ground after weeding, the biodegradable nonwoven fabric sheet including 250 to 800 parts by mass of water or aqueous polymer emulsion liquid with respect to 100 parts by mass of a calcium aluminate-containing substance per 1 mafter being dispersed on a sheet.SELECTED DRAWING: None
【課題】植物の種子と、カルシウムアルミネート含有物質、あるいは、さらに水又は水性ポリマーエマルジョン液を散布した生分解性不織布シート、およびそれを用いた雑草の生育を防止する緑化防草工法を提供する。【解決手段】植物の種子と、ＣａＯ／Ａｌ２Ｏ３モル比が１．３〜３．０のカルシウムアルミネート含有物質を１ｍ２あたり５０〜１０００ｇを分散してなる生分解性不織布シートであり、さらに、水又は水性ポリマーエマルジョン液を上から散布してなる前記生分解性不織布シートであり、水又は水性ポリマーエマルジョン液が、シートに分散した１ｍ２あたり１００質量部のカルシウムアルミネート含有物質に対して、２５０〜８００質量部である前記生分解性不織布シートであり、除草後の地面に前記生分解性不織布シートを敷くことを特徴とする、分散させた植物の種子を繁殖させることで雑草の生育を防止する緑化防草工法、である。【選択図】なし
