| 摘 要： | 对普通膜与光-生双降解膜覆盖下的夏玉米试验结果进行了分析。结果表明,在诱导期之前降解膜与普通膜在增温和保墒方面无明显差异,但在诱导期之后,降解膜的增温和保墒效应明显下降;同时试验表明,覆盖降解膜对解决农田生态环境的“白色污染”具有重要意义。

| Abstract: | An experimental study dealing with summer corn covered by photo-biodegradable polyethylene film was evaluated with control. The results showed that no difference was clearly observed between the degradable polyethylene film and ordinary polyethylene film in terms of soil temperature and soil water content before the abduction period. However, the ability of increasing temperature and reserving water content for the degradable polyethylene were sharply dropped.In addition, it was showed that covering the degradable polyethylene was crucial to resolving so-called "White Pollution" of agriculture ecological environments. |

| Keywords: | photo-biodegradable polyethylene film abduction-period temperature and water content |
