新型地膜覆盖对玉米增产效应试验研究初报

以玉米为试验对象，研究采用不同地膜覆盖对农作物生长及产量的影响。结果表明：覆盖常规地膜、中达转蓝光膜、中达转红光膜均可明显改善玉米生育性状，使成熟期提前10 d，增产效果显著。其中以中达转蓝光膜增产效果最好，667 m2增产达65.57 kg，增产率为10.03%。

Preliminary Report on the Test Study on the Effect of New Plastic Film Mulching on Maize Yield

Using corn as the test object, we studied the different effects of plastic film mulching on the growth and yield of crops. The results show that the coverage of conventional film, blue film, and red film could significantly improve the reproductive traits in maize, reducing the mature time by 10 d, with obvious yield increasing effect. Of these, blue membrane achieved the best effect of increasing the yield of up to 65.57 kg/667 m2, or a yield-increasing rate of 10.03%.
