摘　　要：通过观察毛竹笋期过程，调查毛竹出笋规律，研究其增粗生长规律。结果表明：毛竹竹笋的出笋历期持续16 d左右，其出笋的高峰期在出笋后的第6～11 d，出笋量占全期出笋的56%。毛竹的增粗生长分为3个时期：快速生长期、缓慢生长期和停止期，毛竹茎秆直径的增加主要集中在快速生长期。By observing the process of Phyllostachys edulis shoots, investigating the shooting law and studying diameter growth law of Ph. edulis. The results showed that：the Ph. edulis shoots continuous about 16 d, its shoots peak was in the first 6 ~ 11 d after the shoots and the shooting in this period accounted for 56% of all shoots. The diameter growth of Ph. edulis was classified into three stages： fast growing stage, slow growing stage and ceasing stage, and the increase of the culm diameter was mainly in the fast growing stage.
