本文作者在七十年中期,曾先后提出杉木采用无性系繁殖,生产优良无性系苗木,利用一代优势直接投入生产,并提出采用叶(芽)插等方法,加速无性系苗的生产(见本刊1975年第1期P31—32,35;1977年第1期P28—30),和杉木无性系测定方法(见本刊1978年第4期)。最近作者先后到广东省怀集县林科所和湖南省零陵地区林科所考察,认为大量生产杉木优良无性系苗木,技术问题基本解决,只要有组织的,系统地去做,就能加速实现,故提出本文,以供参考。
In the middle of the seventy years, the author proposed the clonal propagation of Cunninghamia lanceolata to produce excellent clones of seedlings and put them into production with the advantage of one generation. He proposed that the production of clonal seedlings should be speeded up by using leaves (buds) No. 1, 1975, P31-32, 35; No. 1, 1977, P28-30), and the determination of Chinese fir clones (see No. 4 of 1978). Recently, the author visited the Forestry Branch of Huaiji County in Guangdong Province and the Linke Institute in Lingling District of Hunan Province for a long time. He believed that mass production of fine clonal seedlings of Chinese fir would basically solve the technical problems. As long as organized and systematically done, Therefore, this article is presented for reference.
