摘　　要：春玉米与生姜间作是根据二者空间生态位、时间生态位与营养生态位相协调而设计的。本试验以行比为处理，研究了间作后春玉米与生姜的生理特性变化及互补与竞争关系。结果表明：间作的春玉米叶绿素含量、根系活力、光合速率较单作都有提高；而生姜的生理特性则随配置方式及生育期的不同而不同。运用灰色关联分析法对不同配置方式的综合效益进行评价，得出1：2式为春玉米与生姜间作的最优模式。Intercropping of spring maize and ginger was designed on the basis of spacial,time and nutrient coordination between them. The research was conducted by using row proportion as treatment, and studied the changes of physiological characters, the relationship of competetion and mutual benefit between sping maize and ginger after intercropping. The results indicated that chlorophyll content, root activity and photosynthetic rate of intercropped maize were higher than that of maize sole cropping, while ginger's physiological characters were various in different intercropping patterns and growing stages. The synthetical benefits of different treatments were evaluated with the method of grey relational grade analysis, showing that the pattern of 1: 2 row ratio was the best.
