全降解生态地膜在宿州甘薯生产上的应用效果研究

Study on Application Effect of Bio-degradable Ecological Plastic Film on Ipomoea Batatas in Suzhou

目的:初步探讨了全降解生态地膜在甘薯生产上的应用效果,探索解决普通聚乙烯地膜导致农田白色污染的途径。方法:通过安排3种不同配方降解地膜与普通聚乙烯地膜在甘薯上进行覆膜对比试验,不同覆膜时间各处理降解情况以及对甘薯农艺性状及产量影响,以研究不同配方全降解生态地膜降解效果和应用效果。结果:全降解生态地膜降解效果明显,且降解具有可控性。合理设定诱导期的降解地膜对红薯的生长发育及产量影响与普通地膜相当,为全降解生态地膜在生产上进一步推广应用提供科学依据。

[Objective]In this study,the application effect of bio-degradable ecological plastic film on Ipomoea batatas was discussed,our purpose was to explore the way to solve the white pollution of farmland caused by ordinary polyethylene film.[Methods]In order to study the degradation and application effect of different formulations of biodegradable ecological plastic film compared with ordinary plastic film on Ipomoea batatas,the comparative experiment of three different formulations of degradable plastic film was arranged to investigate and detect the degradation at different film covering time,as well as the impact on the agronomic traits and yield of Ipomoea batatas.[Results]The results showed that bio-degradable ecological plastic film was controllable that the degradation effect was also obvious.There was no significantly different on the growth and yield of Ipomoea batatas compared with ordinary plastic film by setting a reasonable induction period.Our research provides a scientific basis for the further application of bio-degradable ecological plastic film in production.
