摘　　要：通过田间试验,研究了不同地膜覆盖对谷子生理特性及产量的影响。结果表明,黑色地膜、白色地膜覆盖处理对谷子出苗率、株高、株质量、穗质量、穗粒质量均有不同程度的提高;与白色地膜和平地裸播相比,黑色地膜覆盖处理在叶绿素含量、水分利用效率、氮元素含量以及产量上具有优势;经济效益方面,黑色地膜、白色地膜的产投比值高于平地裸播。Through field experiment, we studied the influence of different plastic film mulching on physiological characteristics and yield of millet. The results showed that the black film and white film mulching treatment had some increase on corn seedling emergence,plant height, plant weight, spike weight, spike grain weight. Comparing with white film mulching and ground bare sowing, the black film mulching had advantages on the chlorophyll content, water use efficiency, nitrogen content and yield. On the economic efficiency aspect,the input-output ratio of black film and white film were higher than the ground bare sowing.
