Abstract: Effects of three different substrates on growth of Piper kadsura cutting seedlings were studied.The growing regularity of Piper kadsura cutting seedling was analyzed by sequential sample cluster analysis method according to the net growth of seedling,and the management technology for different growing stages were investigated.The results showed that the whole growing process of Piper kadsura could divide into five stages,i.e.,rooting,early-growth,medium-growth,fast-growth,and late-growth stages.The best growing condition of 1-year old cutting seedlings was observed when planted in the substrate consist of 80% peat soil and 20% vermiculite;the seedling rate reached 95% when shading,the seedling height could be 60.6 cm in the same year,and the seedling amount reached 120 thousand plants per 667 m²,which could be transplanted in the same year.Then,based on the growing characteristics of every stage,the management measures were correspondingly proposed.
