目前,由于杉木优树种条不足,严重影响种子园的建设速度。实践证明,利用芽接法建立种条园,能够在短期内为种子园营建提供大量接穗,以满足种子园建设的需要。我场于一九七六年春建立杉木优树采穗圃95亩,定植砧木16,622株,当年嫁接6980株,其中芽接5741株。年终调查,芽接的成活率及保存率达95％以上,最大高生长量有82cm,平均高生长量33.1cm,平均茎粗0.8cm。一九七七年春嫁接9900株,其中芽接8316株,现 At present, due to lack of fir tree species, seriously affecting the construction speed of the seed orchard. Practice has proved that the use of budding method to establish a seed garden, seedlings in the short term construction can provide a large number of scion, to meet the needs of seed orchard construction. In the spring of 1976, we established 95 mu of fir-tree-picking sprouts and planted 16,622 rootstocks. In that year, there were 6980 grafts, of which 5741 were buds. Year-end investigation, budding survival rate and preservation rate of 95% or more, the maximum high growth of 82cm, the average growth of 33.1cm, the average stem diameter of 0.8cm. In the spring of 1977, there were 9900 grafts, of which 8316 were buds
