采集不同年份采穗圃穗条进行嫁接育苗，试验结果表明：穗条的花芽比例越高，接穗的生长量越少；根据釆穗母树的树体结构不同，在树体的不同部位采穗。长林4号和长林40号采集穗条应以上中部为主；长林53号采集穗条应以中下部为主；釆穗圃营建时间长短对嫁接苗质量有显著的影响。随着采穗圃营建时间的增加，苗木根梢的生长呈下降趋势，并且各采穗圃的穗条在苗木根梢生长中表现出显著差异性。

Grafted seedlings were grown with scions collected from different-years scion orchards ,the re-sults showed that:1) The higher proportion of flower buds ,the less biomass of scion growth;2) Scions should be collected at differet positions of the cullting tree according to the frame of the cutting tree;scions should be collected in the middle and top of Changlin 4 and Changlin 40 and in the lower part of Changlin 53;3) The construction time of cutting orchard significantly affected seedling growth .With the increase of construction time of cutting orchard ,the growth of the shoot and root of the seedling declined ,the root shoots of scions collected from different scion-plucking nursery showed significant difference in their growth and shoot growth of the seedling .
