Abstract: 【Objective】 The degradation performance, soil moisture content, maize growth and development, yield of biodegradable film were discussed. 【Methods】 Tianye (Whole Biodegradable Film) and Hongrui (Whole Biodegradable Film), PED (Polyethylene Blown Agricultural Ground Cover Film) were applied and recorded as TZ, TY, HR and CK film to perform maize comparative experiments. 【Results】 The results showed that HR degradable film had advantages over other two kinds of degradable film in terms of explaining intensity. HR degradable film and TY degraded film entered the second degradable stage 10 days earlier than TZ treatment and eventually entered the disintegration stage in the maize harvest period. Compared with CK treatment, the yields of TY and TZ treatment were significantly reduced by 7.1% and 12.44%. There was no significant difference in yield between HR treatment and CK treatment. 【Conclusion】 HR degradable plastic film is more suitable for maize growth characteristics in northern Xinjiang.
