摘要： 为进一步研究验证不同类型环保地膜的田间应用效果，在大田条件下以露地栽培为对照，进行了普通地膜、可降解地膜和液态地膜覆盖玉米栽培试验，对不同地膜覆盖下玉米的生长发育状况、产量及构成因子进行了测定分析。结果表明，可降解地膜覆盖能够明显提高玉米出苗率，比露地对照高5.0%，差异显著；增加地上部干物质积累，使株高、茎粗、叶面积增加，促进穗的生长发育，使秃尖缩短，增加穗粒数和千粒重，产量比露地对照提高40%，差异显著；可降解地膜覆盖效果与普通地膜相似。而液态地膜覆盖对玉米出苗、干物质积累及株高、茎粗、叶面积变化的影响作用较小，虽然在一定程度上提高了玉米产量，但仅比露地对照高0.5%，差异不显著。

Abstract: To further study the effect of different environmental protection films, cultivation experiment of maize with common plastic film, degradable mulch film and liquid film covering were done under fieldconditions with open field cultivation as control. The effect of different films on maize growth and development, yield and component factors were determined. Results showed that the degradable mulching film significantly improved the seedling emergence rate of maize, which was 5.0% higher than that of open field control (0.05 difference); increased dry matter accumulation, the plant height, stem diameter and leaf area, promoted the ear growth, shortened bald tip, increased kernel number per ear, 1000 grain weight, and the yield was 40% higher than that of control (0.05 difference); the effect of the degradable mulch film was similar to that of the common plastic film. However, the liquid film had little effects on maize seedling, dry matter accumulation, plant height, stem diameter, and leaf area, although to a certain extent increased maize yield, which was only 0.5% higher than that of open field control, and the difference did not reach significant level.
