【摘要】 针对普通地膜残膜污染土壤现状,开展了甘薯[Dioscorea esculenta(Lour.)Burkill]覆盖降解膜试验。结果表明,试验所采用的氧化生物双降解生态地膜在试验过程中发生降解且降解持续进行,减轻对农田环境影响的同时,铺膜方式与普通地膜一致,且对甘薯长势和产量无不良影响,可以满足甘薯覆膜栽培需要。更多还原

【Abstract】 For the present situation of soil polluted by plastic film residue,the field experiment of sweet potato [Dioscorea esculenta(Lour.) Burkill] with degradation film was carried out.The results showed that,the oxidative biological degradation film used in this experiment occurred degradation and this degradation was continuous,it could reduce the impact on farmland environment of the plastic film,at the same time the film spreading mode was consistent with ordinary plastic film,and it had the same effects on the growth and yield of sweet potato,it could meet the needs of film mulching cultivation of sweet potato.更多还原
