摘要: 【目的】为筛选出适宜内蒙古乌兰察布市气候条件和种植模式的全生物降解膜,探究不同全生物降解膜的降解情况及其对马铃薯产量性状的影响。【方法】 以6种全生物降解膜为供试材料,以普通地膜(CK1)和裸地无膜(CK2)为对照,共设置8个处理,进行了不同全生物降解膜的比较试验。【结果】 6种全生物降解膜均有不同程度的降解,以T2和T4处理降解效果最好,T1和T3处理次之;在马铃薯生育前期,各覆膜处理的土壤温度均显著高于裸地无膜(CK2)处理(P<0.05),全生物降解膜的保温效果与普通地膜相比差异不大;各覆膜处理的大薯个数、平均大薯重、产量和商品薯率均显著高于裸地无膜(CK2)处理(P<0.05);除T2处理外,其他全生物降解膜覆盖处理的平均大薯重和产量均显著高于普通地膜(CK1)处理(P<0.05)。【结论】 全生物降解膜具有代替普通地膜的生产潜力,就目前试验结果来说,建议在乌兰察布市马铃薯生产中使用T4降解膜。

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.
