摘  要:
以4年生红皮云杉为砧木,年生长量超过10cm的蓝云杉1年枝条为接穗,分不同时期在大棚温室内进行单芽劈接试验。结果表明,4月5日嫁接成活率平均达到89.5%,嫁接时期越早,平均干质量越大。较早嫁接可提高蓝云杉生长期干物质积累量。

摘  要:
Taking shoots of Picea koraiensis as rootstocks,adopting branches of Picea pungens with annual growth of more than 10 cm,the single-shoot splitting tests were conducted in the greenhouses in different periods.Result shows that the average grafting survival rate reached 89.5% on April 5;the earlier the grafting period,the higher the average dry weight.Earlier grafting increased the dry matter accumulation during the growth of Picea pungens.
