Abstract：The application effects of 10 kinds of biodegradable mulch films in spring peanut planting were compared for three consecutive years,and their temperature-increasing,moisture-preserving capabilities,mechanical properties,degradation characteristics,and effects on the growth and development of spring peanuts were systematically evaluated,with the aim of screening out the suitable biodegradable mulch for spring peanuts in the southern Shandong area.The research results showed that the functional period required for spring peanuts in southern Shandong was approximately 70 days.The induction periods of the tested biodegradable mulch films ranged from 30 to 62 days,with an average of about 40 days.Compared to the no-mulch treatment,all tested mulch films could increase the maximum temperature,minimum temperature,and accumulated temperature of the soil 10 cm below the film to varying degrees.The temperature-increasing and moisture-preserving performance of the tested fully biodegradable mulch films was lower than that of standard PE mulch films,but it could basically meet the requirements of water and heat conditions for the growth and development of spring peanuts.This study could guide the scientific use of biodegradable mulch film and solve the problem of residual mulch pollution in farmland.
