摘　　要：地膜覆盖具有提高地温、保持水分、促早熟、增加产量的作用,而普通地膜不环保。现针对"白色污染"情况,进行了可降解地膜、普通地膜和露地栽培玉米的对比试验,探讨可降解地膜的降解性能及对土壤水分、温度和玉米生长发育的影响。结果表明:可降解地膜的土壤温度明显高于露地对照,使玉米出苗率提高,生育进程加快,产量也相应增加。研究认为,可降解地膜在功能上可替代普通地膜。Plastic film mulching could improve the soil temperature, moisture, promote earlyincrease the yield, while the ordinary plastic film is not environmental protection. According to situation of the ＇ white pollution＇, the contrast was tested by the degradable plastic film, ordinary plastic film and open field cultivation of maize, degradation property of degradable mulch film and its effects on soil moisture, temperature and the growth of maize were discussed. The results showed that soil temperature of degradable plastic film was higher than that the control, the emergence rate of maize was increased, the process was accelerated, yield was increased, degradable plastic film could replace the ordinary film in function.
