| Abstract: |
| It is very important to seek some substitutes for plastic film because continuous plastic film mulching cultivation often causes serious soil and environmental contamination．A plant fiber film mulching experiment was carried out to evaluate its applied effect in this study．The results showed that soil temperature and soil moisture significantly increased under the fiber film mulching in seedling stage which is beneficial to improve rate of seedling accelerate growth and improve yield and water use efficiency as well．Compared to open cultivation soil temperature and soil moisture under mulching plant fiber film in different corn growth stages were increased by 0．5℃～1．7℃ and 1．4％～6．1％ respectively as well as 10．8％ of yield．The tensile strength loss ratio of plant fiber film reached over90％ and there was basically no residues on the field in mulching120d which suggests that the plant fiber film could be fully degraded within the plant growing stage. |
