摘　　要：[目的]分析不同覆盖方式处理对谷子农艺性状及光合生理指标的影响。[方法]对不同覆盖处理和平地裸播谷子进行出苗率、株高、生物产量、经济产量、叶片叶绿素含量、叶片氮含量、光合生理指标测定,并进行分析比较。[结果]不同覆盖方式均能在不同程度提高旱作谷子农艺性状和光合生理指标;覆盖白色地膜可明显加快谷子发育进程,缩短生育期;覆盖黑色地膜可以最大幅度提升谷子产量、水分利用效率和产投比。[结论]该研究可以为谷子不同覆盖方式的效果评价提供科学依据。[ Objective ] To analyze the effects of mulching models on the agronomic traits and photosynthetic physiological indexes of millet. [ Method] The germination rate, growth period, plant height, biological yield, grain yield, leaf chlorophyll content, leaf N content, photosynthetic physiological index were detected in different mulching treatments and bare ground millet. [ Result] Different mulching methods could enhance the agronomic traits and photosynthetic physiological indexes of dryland millet. White film mulching significantly accelerated the development process of millet, and shortened the growth period. Black film mulching enhanced the millet yield, water use efficiency and input- output ratio to the maximum degree. [ Conclusion] This research provides scientific basis for the evaluation of the effects of different mulching methods of millet.
