不同郁闭度杉木林下套种的草珊瑚生长差异

摘要

The growth differences of Sarcandra glabra interplanted in the Cunninghamia lanceolata forests were in-vestigated .The results showed that there were significant effects on growth performance of S .glabraby thinning in-tensity method and keeping different canopy density .The ground diameter ,plant height and material product under the canopy density of 0 .7 were significantly higher than those under other treatments ,which was conducive to the growth of S .glabra .%在不同郁闭度杉木人工林下套种草珊瑚，对不同套种时间草珊瑚的生长数据进行调查，结果表明，杉木林通过不同间伐强度抚育措施，杉木人工林保持不同郁闭度，对其下套种的草珊瑚生长表现有显著影响，郁闭度为0.7的处理，草珊瑚的地径、株高和物质产出均显著高于其他处理，有利于草珊瑚的生长。
