摘　　要：[Objective] The aim was to explore application effects of truly biodegradable mulch in farmlands and provide data support for large area spreading on southern potato fields. [Method] The field plot experiments were conducted to investigate mulch film＇s weight loss and the effects of using truly biodegradable mulch film on potato yield and agronomic characters. [Result] The emergence rates of truly biodegradable mulch film and black plastic mulch film kept 9.71% and9.27% higher compared with the open field, and yield increased by 30.84% and36.81%. In the potato harvest period, the truly biodegradable mulch films already broke, and mulch film＇s weight loss rate was 58.62%. It can be completely degraded in the field after some time, and following crops would not be affected. [Conclusion] Truly biodegradable mulch performs significantly in increasing yield and keeps higher in weight-loss rate, so that it has a promising future.[目的]研究全生物降解膜的田间应用效果,为其在南方马铃薯种植上大面积推广提供数据支持。[方法]通过田间小区试验,研究了地膜的降解失重率以及使用全生物降解膜对马铃薯产量及农艺性状的影响。[结果]马铃薯种植使用全生物降解地膜、普通黑膜的出苗率分别比露地种植高出9.71和9.27个百分点;产量分别增加30.84%和36.81%,增产效果明显。同时,在马铃薯收获期,全生物降解地膜已基本破碎,降解失重率达到58.62%,在田间一段时间后可完全降解,不影响下茬作物的生长。[结论]全生物降解地膜增产效果显著,降解失重率高,综合效益好,具有广泛的应用前景。
