Abstract: 【Objective】 To select suitable whole biodegradable film for Inner Mongolia Ulanqab area climate condition and cultivation mode,to explore the degradation situation of different whole biodegradable film and its influence on potato yield trait. 【Methods】 6 kinds of whole biodegradable membrane were used as material,with an ordinary film (CK1) and bare land without membrane (CK2) for comparison. The experiment was carried out by setting up eight treatmeats. 【Results】 All the 6 kinds of whole biodegradable membranes have different degrees of degradation,and T2 and T4 have the best degradation effect,followed by T1 and T3. In the early period of potato growth,the soil temperature of each film mulching treatment was significantly higher than that of the bare land film-free (CK2) treatment (P<0.05). The insulation effect of whole biodegradable film was not significantly different from that of the ordinary plastic film. The number of large potato,the average potato weight,yield,and the commercial potato rate of each mulching treatment were significantly higher than that of the open-field film-free (CK2) treatment (P<0.05). With the exception of T2 treatment,the average potato weight and yield of other total biodegradable film mulching treatments were significantly higher than that of the ordinary plastic film (CK1) treatment (P<0.05). 【Conclusion】 The whole biodegradable film has the production potential to replace the ordinary plastic film. Based on the current experimental results,it is recommended to use T4 degradation film in potato production in Ulanqab region.
