摘　　要：该文以不同水分处理玉米模拟土柱试验结果为根据,既定性又定量地阐述了叶面积、株高、体积及密度与土壤湿度的关系及各自的时间动态;相对生物产量、相对经济产量与无量纲土壤湿度的关系;经济产量、水分生产效率与耗水量的关系。According to soil column simulation experiment growing with spring corn under different water Content,the rela-tionship between soil water concentration and corn leaf area, height,root dencity was studied seperately qualitativelyand quantitatively. And also,that between nondimensinal soil humidity and both ralative biomass and yield as well asbetween water efficiency and its consumption was disscussed in the paper.
