摘　　要：2018年2月上旬,抽样调查了平坝和威宁国家华山松良种基地2015年~2017年不同培育方式培育的华山松苗木,调查数据统计分析结果表明:华山松营养袋苗的地径和苗高随着苗龄的增长而变大,不同育苗地点变化有差异,威宁育苗点的苗木生长表现显著低于平坝育苗点;华山松不同种类苗木生长表现差异达到极显著水平,平坝3年营养钵苗的平均地径17.23mm、苗高74.3cm,营养袋苗地径10.59mm、苗高69.4cm,裸根苗地径8.37mm、苗高37.0cm;平坝和威宁两地营养袋苗的生长表现差异达到极显著水平。不宜采用苗木生长表现绝对数值来比较不同地点的苗木生长水平及育苗技术水平;贵州高寒山区困难立地造林建议使用2~3年营养袋苗造林,立地条件相对较好的使用3年营养钵苗。In early February of 2018,pinus armandii seedlings cultivated in different ways in Pingba and Weining National Pinus armandii Seed Base from 2015 to 2017 were sampled and investigated.The results showed that the diameter and seedling height of Pinus armandii nutrition bag seedlings increased with the increase of seedling age,and there were differences among different seedling-raising sites.The seedling growth of Weining seedling-raising site was significantly lower than that of Pingba seedling-raising site.The Pinus armandii seedlings growth of different ways varies greatly.The average ground diameter and seedling height of three years’nutritional bowl seedlings in Pingba were 17.23 mm and 74.3 cm respectively,the ground diameter and the seedling height of nutrition bag seedlings were 10.59 mm and 69.4 cm,the ground diameter and the seedling height of bare-root seedlings were 8.37 mm and 37.0 cm.The growth difference of nutrition bag seedlings between Pingba and Weining reached a very significant level.The absolute value of seedling growth should not be used to compare the seedling growth level and seedling raising technology in different locations.It was suggested to use 2-3 years nutrition bag seedlings for afforestation on difficult sites in Guizhou Alpine mountainous areas,and 3 years nutritional bowl seedlings on relatively good site conditions.
