[Objective]Effect of container seedling densities on the quality of Melia azedarach seedlings was studied.[Method]In this experi-ment,we used mixed medium(loess :turf :perlite =1.0 :1.0 :0.2),setted different densities (36,64,100 bags/m2) and determined the morphological and physiological indexes of the seedlings to study the effect of container seedling densities on the quality of M.azedarach seed-lings.[ Result] The results showed that the seedling uniformity and quality were significantly affected by container seedling densities,the seed-lings at the density of 64 bags/m2 grew best in the whole period,which were most suitable for afforestation.[Conclusion]We must adopt ration-al container seedling densities, so as to ensure the quality of seedlings and output.%[目的]研究容器苗密度对苦楝苗木质量的影响.[方法]采用黄心土:泥炭:珍珠岩(1.0:1.0:0.2)混合基质,设置不同容器苗密度处理(36、64、100袋/m2),测定苗木的形态指标和生理指标等,研究容器苗密度对苦楝苗木质量的影响.[结果]容器苗密度对苗木的整齐度及苗木质量的影响很大,64袋/m2的摆放密度下所育苗木整体表现最好,宜于造林.[结论]容器苗育苗时必须采取合理的密度,从而保证苗木质量和产出.
