为揭示油莎豆块茎的形成规律，采用自然种植、定期采样观察等方法对三种不同油莎豆品系块茎的形成过程进行详细观测，结果表明：这三种油莎豆的分蘖数、匍匐茎形成时间、匍匐茎长度及直径、块茎开始膨大形成时间、每株形成块茎数量、块茎大小及形态、块茎在土壤中分布格局等性状存在显著差异，说明不同品系油莎豆的块茎形成特性不同，可为油莎豆的栽培和开发利用提供参考。

The paper focused on the tuber formation of Cyperus esculentus. The development and growth of tubers in three strains (Puyuan No.5, Puyuan No.6 and Puyuan No.3 ) were observed and compared by means of natural plant method and sampling method. The preliminary results showed that there were evident differences in tillering number, the initial time of stolons formation, the stolon length and diameter, the initial time of tuber swelling, the tuber number per plant, tuber size and shape and the distribution of tubers in soil aˉ mong three chufa strains. It provided the scientific basis for further study on tuber formationg, development and utilization of Cyperus es-culentus.
