| Abstract: |
| The application and development,as well as the problem in producing and utilizing biodegradable mulch film are presented. A new principle and technology named of wet mulching is developed. The effect on modeling mechanism and film properties of mulch film is studied. By using this new technology,the manufacture periods and the requirement on the film strength can be greatly reduced. It will be advantageous to use the biological material in film production. |
| Key words: mulch film covering,biological material,degrade |
