摘要
引进12个杉木无性系扦插苗作2片造林对比试验,8年生时无性系间的高生长、胸径生长存在显著差异,高生长9个超过对照,胸径生长4个超过对照。本省12个优良家系无性繁殖造林对比试验,6年生树高间差异显著,高生长7个超过对照。可提供采穗圃或良种选育材料。
The cutting plants of 12 Cunninghamia lanceolata clones were introduced to make a comparative experiment on two tracts of forests through planting.The differences of height growth and dbh growth were notable among 8 year old clonal saplings.The height growth of 9 clones surpassed that of the control and the dbh growth of 4 clones surpassed that of the control.The comparative experiment on the asexual propagation planting of 12 excellent families in our province was also conducted.The difference of height growth among 6 year old saplings was also significant and the height growth of 7 families surpassed that of the control.They could provide the materials for scion plucking nurseries or for fine variety breeding.
