| 摘 要： | 可降解地膜是解决常规塑料地膜引起的白色污染的有效途径。通过试验研究了生物降解膜自然降解过程及其对玉米生长的影响。研究结果表明：（1）生物降解膜降解60和100d后的降解率分别为1.26%和1.91%,而且降解率随着时间的延长而增加;（2）生物地膜在降解前与普通地膜在提高土壤温度方面有着一致的效果,其增温效应与普通膜没有明显的差异;（3）较CK处理,覆盖生物膜时玉米穗上叶、穗位叶和穗下叶叶面积分别增加了10.83%,9.38%和7.94%,可以促进玉米的生长发育进程;（4）生物膜具有极显著的增产作用,比CK处理增产18.7%,但增产效果与普通膜之间差异不显著。 |

| Abstract: | Using biodegradable films are an efficient approach to reduce the white pollution by traditional plastic film which could remain in soils for hundred years.The degradation characteristics of biodegradable mulch films and its effect on the growth of maize were analyzed and tested.The results indicated that:(1) The degradation percentage of biodegradable mulch films was 1.26% within 60 days and 1.91% within 100 days respectively,and the remained film degraded greatly afterward.(2) No obvious difference has be... |
| Keywords: | biodegradable mulch film maize soil temperature yield |
