生物材料地膜田间成型湿铺工艺的试验研究

Buried-in Site Technology of Wet Mulch Film

介绍了可降解地膜的应用和发展，分析了可降解地膜制造和使用中的问题，提出了一种新的生物材料地膜成型原理──田间成型湿铺。研究了各种成膜材料对成膜工艺及膜性能的影响，并进行了相应的成膜工艺和模拟失效试验。田间成型湿铺工艺减少了成膜周转环节，降低了对膜强度的要求，有利于生物材料在地膜生产中的应用。

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.
