摘要: The main challenges for the development of agricultural bio-degradable mulching film concern degradation during lifetime cultivated crops. A set rice by-product (rice-hull and rice-bran) based films was developed tested, following measurement standard bio-degradability rate adaptability in a large scale field experiment. bio-film passed KS (Korea standard) regulation. result mechanical analysis presented higher strength elongation compared with polyethylene film. In addition, could be degraded into fragments within 4 months under condition several upland Bio-degradable indicated great potential as new source material.
