| Abstract: | 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. |
