Abstract: In recent years, degradable plastic film, as one of the main means to control white pollution, has enlarged its popularization area year by year, but the performance of various types of degradable plastic film is uneven. The systematic study of degradable plastic film on crop growth, development and residues is rare. The comparative experiments of different types of degradable plastic film on peanut were carried out by means of comparative test and whole growth period monitoring. The effects of different degradable plastic film on the growth and development of spring peanut and the residual situation of plastic film were preliminarily grasped. The results showed that the performance of ordinary plastic film and oxidized biodegradable plastic film was better than that of ordinary plastic film in soil moisture conservation. The thermal insulation effect of degradable plastic film was slightly better than that of ordinary plastic film in the induction period. The yield of degradable plastic film was increased in varying degrees and the residue rate was obviously lower, but the degradation characteristics were different, the induction period was different, the degradation rate of oxidized biodegradable plastic film was unstable, the rate was different, and individual total degradation was different. The induction period of plastic film was shorter and the effect was not obvious. The four degradable plastic films showed that the longer the induction period, the higher the peanut yield, the faster the degradation of the border part, and the slower the degradation of the covering part.
