무기소재 첨가에 따른 멀칭용지의 기능성 변화

Abstract

The biodegradable mulching paper could be applied for the environmental friendly agriculture as an alternativeto the current vinyl mulching. In order to increase the usability of the mulching paper, the effectsof the addition of various inorganic materials on the functionality of the mulching paper were evaluatedin terms of practical benefits. The blend of carbonized rice husk powder and perlite resulted in the highervalue in the air permeability of the mulching paper, which would be important for the health of plant root. The heat conservative of the mulching paper could be improved by adding the bottom ash or the fly ashbecause of the pore structure of the ashes. The pH of acidic soil could be neutralized by using the mulchingpaper containing paper-mill sludge ash or fly ash. The various results showed the addition of the inorganicmaterials could improve the functional properties of the mulching paper.
