| 摘 要： | 以“西玉3号”玉米为试验材料，作了覆膜与露地两种方式的对比种植，研究了其生态小气候效应、植株生长特点及其对玉米产量的影响。结果表明：采用地膜覆盖在生育前期能提高土壤温度，保持土壤湿度，生育后期特别是旺盛生长期能降低土壤温度，有效改善土壤的物理性状，从而显著改善玉米生育期内的生态小气候效应，最终能够提高玉米子粒产量。

| Abstract: | The experiment was conducted in two different planting patterns (film-covering and non film-covering) with West-3 maize.Its ecosystem microclimatic effect, the characteristics of plant growth, and its influence on corn yield were studied.The results showed:film-covering could increase soil temperature,keep the soil humidity in earlier growing stage, and could drop soil temperature during the full growing stage.In addition, film-covering could remarkably improve the soil's physical character and improve ecosystem microclimatic effect in maize growing period.Finally it could increase corn yield. |
