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