摘　　要：针对９０年代种植制度变革的新特点，分析了间套作、复种及复种指数的意义，讨论了区别间套作的共生期标准、作物标准熟期与熟数系数以及面积系数等概念，提出了多样化的多元多熟种植条件下复种指数的计算规则和方法。In accordance with the new characteristics of the cropping system in 1990s,the significance of intercropping,relay cropping,multiple cropping and cropping index was analyzed in this paper.The standard of distinguishing intercropping from relay cropping,which includes crop intergrowth period,crop maturing time,crop harvest time and coefficient,was discussed.Finally,some rules and a method of calculating cropping index of diversified multiple cropping systems were proposed.
