Introduction
1. Background of Standard Formulation
With the increasingly serious global environmental problems, especially the white pollution caused by the residual film on farmland, the formulation of standards for fully biodegradable agricultural ground covering films is particularly important. The introduction of GB/T 35795-2017 "Fully Biodegradable Agricultural Ground Covering Film" aims to regulate the market, promote the sustainable development of agriculture, and reduce the negative impact on the environment.
2. Comparison of standard frameworks
| Standard dimensions | GB/T 35795—2017 | Comparison standards |
|---|---|---|
| Scope of application | Fully biodegradable agricultural mulch film | Traditional plastic mulch film |
| Material requirements | Degradable materials such as aliphatic polyester | Non-renewable polymer materials |
| Testing indicators | Biodegradation performance, mechanical properties, water vapor transmission rate | Basic physical properties such as tensile strength and thickness |
3. Analysis of Technological Evolution
Fully biodegradable materials have evolved from simple starch addition to fully degradable resins. GB/T 35795-2017 uses advanced aliphatic polyester and carbon dioxide copolymer technology to significantly improve the weather resistance and decomposition efficiency of the film.
Actual application case:A farm in Xinjiang uses the mulch produced using this standard, which not only effectively inhibits weed growth, but also significantly reduces soil compaction problems, and does not cause any negative impact on crops after degradation.
4. Implementation Recommendations
Promotion strategy:The government should increase policy support, encourage companies to adopt new materials and processes, and at the same time carry out farmer training to improve environmental awareness.
Quality monitoring:Strengthen market sampling to ensure that products meet standard requirements and prevent counterfeit and shoddy products from entering the market.
