▎ 摘　　要

NOVELTY - A degradable mulching film comprises 30-60 pts. wt. ethylene acrylic acid, 20-40 pts. wt. modified starch, 10-20 pts. wt. sodium alginate, 0.5-5 pts. wt. photosensitizer, 0.5-1.5 pts. wt. plasticizer, 0.5-1.5 pts. wt. heat stabilizer and 0.5-1 pt. wt. graphene. USE - Degradable mulching film used for saline-alkali soil cultivation. ADVANTAGE - The film has fast degrading speed and high intensity, does not pollute land without affecting structure of saline-alkali soil and prevents aggravating damage to saline-alkali soil structure, which is good for plant growth.
