摘　　要：为选择优良种源和播种育苗方法,对千金鹅耳枥(Carpinus cordata)进行了不同种子来源、不同覆土措施、不同播种条件的播种试验,结果显示:不同来源种子出苗率及苗高、地径存在显著差异,以吉林市小区HB63L1个体最好,出苗率达88.5%,树高达48.7 cm,地径达4.7 mm;不同覆盖措施对苗高影响显著,对出苗率、地径的影响不显著,苗高以先覆一层沙子再盖一层土效果较好,苗高达42.0 cm;播种条件以温室优于露天,室内出苗率、苗高、地径分别是露天的129%、143%和133%。In order to select excellent provenance and methods of seeding and seedling nursing methods,seeding experiments were carried out on Carpinus cordata with different seed sources and soil coverings under different seeding condition.The results showed that there were significant differences in seedling emergence rate,seedling height and ground diameter among different seed sources.One of them HB63#L1 in Jilin City had the best individual which emergence rate was 88.5%,height of tree was 48.7 cm,diameter of ground was 4.7 mm.The difference of mulching measures on seedling height was significant,but were not obvious on the emergence rate and ground diameter.Seedling height was better,up to 42.0 cm,by covering method that cover a layer of sand before a layer of soil.Seeding condition in greenhouse was better than that in the open air,and the greenhouse seedling emergence rate,seedling height and ground diameter were 129%,143%and 133%,respectively.
