The invention discloses a special ultra-thin degradable mulch film for sugar beet, which is prepared from the following raw materials in parts by mass: 100 parts of degradable polymers, 0.5-3.5 parts of hydrophobic blocking agent, 2-5 parts of antibacterial slow-release agent, and light-resistant degradation agent 2-5 parts, tear-resistant agent 0.5-2 parts. The thickness of the mulch film is less than 6μm, which not only has mechanical properties comparable to traditional PE mulch film, but also increases sugar beet yield and sugar content. It is degradable, low in cost, and has great application value, good economic benefits and social benefits benefit. |
