摘　　要：为建设杉木丰产林基地,引进浙江开化林场12个杉木无性系扦插苗在Ⅲ类地上分2片进行造林试验.结果表明:13年生时各无性系间在树高、胸径、冠幅、单株平均材积生长量上存在极显著或显著差异;其中38号表现最好,13年生树高达13.02 m,胸径达16.82 cm,单株平均材积0.147 0 m3;与实生苗对照比,57号、28号可作为采穗、繁育材料;110号、3号、38号可在进一步试验后推广.Two patches of planting experiments were implemented on category Ⅲ forest land with 12 clones of Cunninghamia lanceolata saplings introduced from Kaihua Forest Farm, Zhejiang Province in order to establish bumper timber production base. The saplings used in the experiments were bred by cuttage method. It was showed by the results that there were extremely significant or simply significant differences among different clones in plant height, DBH, crown diameter and standing volume 13 years after the experimental planting was done. Among the 8 clones, Clone No. 38 did the best, whose average plant height reached 13.02 m, with 16.82 cm in DBH, and the standing volume per plant was 0. 1470m^3. Compared to seedlings bred from seeds as control, Clone No. 57 and Clone No. 28 were better for producing cuttings for future propagation, Clones No. 110, No. 3 and No. 38 were recommended for extended planting after further experiment.
