<p><P>PROBLEM TO BE SOLVED: To provide a sheet usable for plant culture, or the like, produced in order to develop new use of vegetable-fiber products, in particular, as a preservation package material for fresh food through negative ionization. <P>SOLUTION: The sheet usable for plant culture is obtained by imparting negative ion-radiating properties to vegetable fiber cloth comprising polylactic acid fiber so as to be effective as the preservation package material for fresh food or a protection sheet for plant culture. The vegetable fiber cloth is preferably soaked in supernatant liquid (or filtrate) obtained by mixing water with a negative ion-radiating mineral ore. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
