摘　　要：2007~2009年在普洱景谷进行了不同类型思茅松苗木造林对比试验,通过调查思茅松扦插苗与实生苗山地栽培的生长情况,分析了扦插苗留圃时间长短对造林初期思茅松生长的影响及不同育苗基质培育的扦插苗对造林初期生长的影响情况。结果表明,思茅松扦插苗与实生苗山地栽培2年3个月后,在树高生长方面差异显著,而地径生长差异不显著,林木生长量是扦插苗好于实生苗;思茅松扦插苗在生根良好的前提下,扦插留圃时间长短对幼树生长无明显影响;林下表土与树皮碎片（1？1）混合的育苗基质所培育的扦插苗,造林后其地径、树高生长明显好于育苗基质为林下土的扦插苗。Using afforestation comparison method to study the rules of growth of cuttage and seedling planting of Pinus kesiya var.langbianensis,the survey was taken 2 years later（duration of April,2007-April,2009）.The impacts of duration of cuttage conserved in nursery and different types of culture on early seedling growth were studied.It showed that both types of planting were significant divergence in tree height,while not so in DAB（diameter at base） in 2 years.And cuttage planting was better than seedling planting in mass growth of the tree.Under the condition of well-developed rooting,the effect of duration of cuttage conserved in nursery was not significant.The culture with mixed superficial forest soil and bark chip（1︰1） for cuttage planting were better in DAB and height increment than that of sole superficial forest soil.
